Background: Severe traumatic brain injury often leads to death from withdrawal of life-sustaining therapy, although prognosis is difficult to determine.Methods: To evaluate variation in mortality following the withdrawal of life-sustaining therapy and hospital mortality in patients with critical illness and severe traumatic brain injury, we conducted a two-year multicentre retrospective cohort study in six Canadian level-one trauma centres. The effect of centre on hospital mortality and withdrawal of life-sustaining therapy was evaluated using multivariable logistic regression adjusted for baseline patient-level covariates (sex, age, pupillary reactivity and score on the Glasgow coma scale).Results: We randomly selected 720 patients with traumatic brain injury for our study. The overall hospital mortality among these patients was 228/720 (31.7%, 95% confidence interval [CI] 28.4%-35.2%) and ranged from 10.8% to 44.2% across centres (χ(2) test for overall difference, p < 0.001). Most deaths (70.2% [160/228], 95% CI 63.9%-75.7%) were associated with withdrawal of life-sustaining therapy, ranging from 45.0% (18/40) to 86.8% (46/53) (χ(2) test for overall difference, p < 0.001) across centres. Adjusted odd ratios (ORs) for the effect of centre on hospital mortality ranged from 0.61 to 1.55 (p < 0.001). The incidence of withdrawal of life-sustaining therapy varied by centre, with ORs ranging from 0.42 to 2.40 (p = 0.001). About one half of deaths that occurred following the withdrawal of life-sustaining therapies happened within the first three days of care.Interpretation: We observed significant variation in mortality across centres. This may be explained in part by regional variations in physician, family or community approaches to the withdrawal of life-sustaining therapy. Considering the high proportion of early deaths associated with the withdrawal of life-sustaining therapy and the limited accuracy of current prognostic indicators, caution should be used regarding early withdrawal of life-sustaining therapy following severe traumatic brain injury.

Interaction with a lay referral system (informal networks that provide health advice during illness) influences the treatment-seeking decisions of individuals with perceived healthcare needs. We examined how this occurred in urban slums in Nigeria with scarce formal healthcare and unstable social networks. Using existing theories of social networks and lay referral, we examined the use of these systems for treatment-seeking decisions in slums, including the use of digital technologies. We interviewed 30 adults (aged 18-64) of diverse age, gender, network size and use of digital technologies for health advice in two Nigerian slums. We analysed the data using a thematic inductive-deductive approach. Lay referral was multidimensional: discussion of illness during daily bonding, social demonstration of self and purposeful exchange of support. People limited lay referrals to a few family members and friends, avoiding wider interactions due to mistrust. Use of online sources was scarce due to limited access to smart devices and low digital health literacy. Lay referral motivated timely care seeking but also facilitated unhelpful advice. Slum residents were agentic in their use of their lay referral system. The effectiveness of their agency may be improved if trusted and reliable health advice sources are available in addition to their social network., (© 2024 The Author(s).

Background: The Recommended Summary Plan for Emergency Care and Treatment (ReSPECT) is designed to facilitate meaningful discussions between healthcare professionals, patients, and their family about preferences for treatment in future medical emergencies. People with a learning disability may face particular barriers in completing health care plans and receiving emergency treatment, however little is known about their preferences towards emergency care treatment planning. This study explores the views of people with a learning disability, and family carers about ReSPECT., Methods: A reference group of 5 people with a learning disability contributed to the design of the workshops and evaluation of outputs. Online, arts-based interactive workshops were held with 2 groups of 6 people with a learning disability to explore how they felt about emergency care treatment planning, and to co-produce materials to support ReSPECT conversations. Carers of people with a learning disability participated in focus groups or interviews. Data from workshops, focus groups and interviews were analysed thematically., Results: Themes were; Getting the Process Right, Lack of trust a barrier to ReSPECT planning, and Person-Centred Care. All groups supported the ReSPECT process feeling that ReSPECT plans could support person-centred care, enhancing the autonomy of a person with a learning disability and supporting the advocacy of carers. However, drawing on their previous experiences of the health care system some expressed doubt that their wishes would be carried out. Suggestions were made for improving the ReSPECT process and used to develop resources to support ReSPECT planning., Conclusions: Emergency care planning and ReSPECT are viewed positively by people with a learning disability and family carers. To ensure this works well for people with a learning disability attention should be given to reasonable, personalised adjustments to support their participation in planning conversations. There is a wider challenge of fostering trust in the health care system., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Russell AM et al.)

Background: Emergency care treatment plans provide recommendations about treatment, including cardiopulmonary resuscitation, to be considered in emergency medical situations. In 2016, the Resuscitation Council United Kingdom developed a standardised emergency care treatment plan, the recommended summary plan for emergency care and treatment, known as ReSPECT. There are advantages and potential difficulties in initiating the ReSPECT process in primary care. Hospital doctors and general practitioners may use the process differently and recommendations do not always translate between settings. There are no large studies of the use of ReSPECT in the community., Study Aim: To evaluate how, when and why ReSPECT is used in primary care and what effect it has on patient treatment and care., Design: A mixed-methods approach using interviews, focus groups, surveys and evaluation of ReSPECT forms within an analytical framework of normalisation process theory., Setting: A total of 13 general practices and 13 care homes across 3 areas of England., Participants: General practitioners, senior primary care nurses, senior care home staff, patients and their relatives, community and emergency department clinicians and home care workers, people with learning disability and their carers. National surveys of (1) the public and (2) general practitioners., Results: Members of the public are supportive of emergency care treatment plans. Respondents recognised benefits of plans but also potential risks if the recommendations become out of date. The ReSPECT plans were used by 345/842 (41%) of general practitioner survey respondents. Those who used ReSPECT were more likely to be comfortable having emergency care treatment conversations than respondents who used standalone 'do not attempt cardiopulmonary resuscitation' forms. The recommended summary plan for emergency care and treatment was conceptualised by all participants as person centred, enabling patients to have some say over future treatment decisions. Including families in the discussion is seen as important so they know the patient's wishes, which facilitates decision-making in an emergency. Writing recommendations is challenging because of uncertainty around future clinical events and treatment options. Care home staff described conflict over treatment decisions with clinicians attending in an emergency, with treatment decisions not always reflecting recommendations. People with a ReSPECT plan and their relatives trusted that recommendations would be followed in an emergency, but carers of people with a learning disability had less confidence that this would be the case. The ReSPECT form evaluation showed 87% (122/141) recorded free-text treatment recommendations other than cardiopulmonary resuscitation. Patient preferences were recorded in 57% (81/141). Where a patient lacked capacity the presence of a relative or lasting power of attorney was recorded in two-thirds of forms., Limitations: Recruitment for patient/relative interviews was less than anticipated so caution is required in interpreting these data. Minority ethnic groups were under-represented across our studies., Conclusions: The aims of ReSPECT are supported by health and social care professionals, patients, and the public. Uncertainty around illness trajectory and treatment options for a patient in a community setting cannot be easily translated into specific recommendations. This can lead to conflict and variation in how recommendations are interpreted., Future Work: Future research should explore how best to integrate patient values into treatment decision-making in an emergency., Study Registration: This study is registered as NCT05046197., Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme (NIHR award ref: NIHR131316) and is published in full in Health and Social Care Delivery Research; Vol. 12, No. 42.

Objectives: To measure community attitudes to emergency care and treatment plans (ECTPs)., Design: Population survey., Setting: Great Britain., Participants: As part of the British Social Attitudes Survey, sent to randomly selected addresses in Great Britain, 1135 adults completed a module on ECTPs. The sample was nationally representative in terms of age and location, 619 (55%) were female and 1005 (89%) were of white origin., Outcome Measures: People's attitudes having an ECTP for themselves now, and in the future; how comfortable they might be having a discussion about an ECTP and how they thought such a plan might impact on their future care., Results: Predominantly, respondents were in favour of people being able to have an ECTP, with 908/1135 (80%) being at least somewhat in favour. People in good health were less likely than those with activity-limiting chronic disease to want a plan at present (52% vs 64%, OR 1.78 (95% CI 1.30 to 2.45) p<0.001). Developing a long-term condition or becoming disabled would lead 42% (467/1112) and 43% (481/1112) of individuals, respectively, to want an ECTP. More, 634/1112 (57%) would want an ECTP if they developed a life-threatening condition. Predominantly, 938/1135 (83%) respondents agreed that an ECTP would help avoid their family needing to make difficult decisions on their behalf, and 939/1135 (83%) that it would ensure doctors and nurses knew their wishes. Nevertheless, a small majority-628/1135 (55%)-agreed that there was a serious risk of the plan being out of date when needed. A substantial minority-330/1135 (29%)-agreed that an ECTP might result in them not receiving life-saving treatment., Conclusions: There is general support for the use of ECTPs by people of all ages. Nevertheless, many respondents felt these might be out of date when needed and prevent people receiving life-saving treatment., Competing Interests: Competing interests: MU is chief investigator or co-investigator on multiple previous and current research grants from the UK National Institute for Health Research (NIHR), and is a co-investigator on grants funded by the Australian NHMRC and Norwegian MRC.

Background: The Recommended Summary Plan for Emergency Care and Treatment (ReSPECT) includes agreed clinical recommendations for a person's care in a future emergency which have been informed by discussion of the person's preferences. Previous evaluation of ReSPECT plans in acute NHS hospitals found inconsistencies in recording patient's preferences and involvement in the plan, and infrequent justification for recommendations., Aim: To explore to what extent ReSPECT recommendations reflect individual preferences, as documented in the plan., Methods: ReSPECT plans of adults were collected from 11 General Practices in England. We adapted an evaluation tool used previously to analyse ReSPECT plans in acute settings. Free text sections for individual values/preferences and clinical recommendations were examined for clarity, consistency and congruency between them., Results: We retrieved 141 ReSPECT plans. Patients or those close to the patient were recorded as being consulted in most plans (94%). Individual preferences were completed in 57% of plans. Clinical recommendations reflected individual preferences by directly referencing the person and their preferences (31%), by being consistent with the documented preferences (30%), or by using the same wording as the preferences (6%)., Conclusion: While many clinical recommendations reflect individual preferences, the preferences themselves are only recorded in just over half of ReSPECT plans. This is problematic, because the recording of individual preferences facilitates person-centred care, both directly by informing recommendations and indirectly when used to guide decision-making in situations not anticipated in the plan. Future training for clinicians should emphasize the need to document the personal values section of the plan., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: GDP is a Vice President and a member of the ReSPECT subcommittee of the Resuscitation Council UK, a volunteer Director for the European Resuscitation Council and co-chair for the International Liaison Committee on Resuscitation, Editor for Resuscitation and Resuscitation Plus.

Background The Recommended Summary Plan for Emergency Care and Treatment (ReSPECT) has been implemented in many areas of the UK. It is unclear how ReSPECT is used in primary and community care settings. Aim To investigate how the ReSPECT process is understood and experienced in the community by clinicians, social care staff, patients, their relatives, and identify obstacles and enablers to its implementation. Design and setting. A qualitative interview and focus group study across 13 general practices in three areas in England. Method We interviewed GPs, specialist nurses, patients and relatives, and senior care home staff. Focus groups were conducted with community-nurses, paramedics, and home-care workers. Questions focused on understanding experiences of and engagements with ReSPECT. We analysed data using thematic analysis and a coding framework drawn from Normalisation Process Theory. Results Participants included 21 GPs, five specialist nurses, nine patients, seven relatives, 31 care home staff, nine community nurses, seven home-care workers and two paramedics. Participants supported ReSPECT regarding it as a tool to facilitate person-centred care. GPs faced challenges in timing introduction of ReSPECT and ensuring sufficient time to complete plans with patients. ReSPECT conversations worked best when there was a trusting relationship between clinician and patient (and their family). Anticipating future illness trajectories was difficult yet plans were rarely reviewed. Interpreting recommendations in emergencies was challenging. Conclusion The ReSPECT process has not translated as well as expected in the community setting. A revised approach is needed to address the challenges of implementation in this context., (Copyright © 2024, The Authors.)

Background: In England, voluntary sector specialist (VSS) services are central to supporting victim-survivors of sexual violence (SV). However, empirical evidence is lacking about the scope, range and effectiveness of VSS provision for SV in England., Objectives: To undertake national surveys to map SV VSS service provision and describe arrangements for funding and commissioning., Design: Cross-sectional surveys., Setting: VSS services for SV and commissioners from multiple organisations across England (January-June 2021)., Methods: Senior staff working in VSS services and commissioners from multiple organisations were surveyed electronically. Surveys explored SV service commissioning, funding and delivery, partnerships between organisations, perceived unmet need for services, and views about facilitators and challenges. Data were analysed descriptively to characterise VSS service provision for SV and commissioning across England., Results: 54 responses were received from VSS providers and 34 from commissioners. Data demonstrated a complex and evolving funding and commissioning landscape in which providers typically secured funding from multiple sources, impacting consistency and scope of service provision. It was common for multiple organisations to co-commission services, demonstrating trends towards larger contracts that may disadvantage smaller specialist providers. Numerous examples of partnership working between organisations were identified, although developing partnerships was noted as challenging, particularly between VSS organisations. There was clear evidence of unmet need for services, with some groups of victim-survivors such as those from black and minority ethnic groups, often underserved by specialist services. However, there was also evidence of innovative service development and commissioning approaches to meet the needs of victim-survivors who face challenges accessing services., Conclusions: This study provides novel insights into SV service provision and commissioning in England, including unmet needs among victim-survivors., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: The amount of same-day surgery has increased markedly worldwide in recent decades, but there remains limited evidence on chronic postsurgical pain in this setting., Methods: This study assessed pain 90 days after ambulatory surgery in an international, multicenter prospective cohort study of patients at least 45 yr old with comorbidities or at least 65 yr old. Pain was assessed using the Brief Pain Inventory. Chronic postsurgical pain was defined as a change of more than 1 point in self-rated average pain at the surgical site between baseline and 90 days, and moderate to severe chronic postsurgical pain was defined as a score greater than 4 in self-rated average pain at the surgical site at 90 days. Risk factors for chronic postsurgical pain were identified using multivariable logistic regression., Results: Between November 2021 and January 2023, a total of 2,054 participants were included, and chronic postsurgical pain occurred in 12% of participants, of whom 93.1% had new chronic pain at the surgical site (i.e., participants without pain before surgery). Moderate to severe chronic postsurgical pain occurred in 9% of overall participants. Factors associated with chronic postsurgical pain were active smoking (odds ratio, 1.82; 95% CI, 1.20 to 2.76), orthopedic surgery (odds ratio, 4.7; 95% CI, 2.24 to 9.7), plastic surgery (odds ratio, 4.3; 95% CI, 1.97 to 9.2), breast surgery (odds ratio, 2.74; 95% CI, 1.29 to 5.8), vascular surgery (odds ratio, 2.71; 95% CI, 1.09 to 6.7), and ethnicity (i.e., for Hispanic/Latino ethnicity, odds ratio, 3.41; 95% CI, 1.68 to 6.9 and for First Nations/native persons, odds ratio, 4.0; 95% CI, 1.05 to 15.4)., Conclusions: Persistent postsurgical pain after same-day surgery is common, is usually moderate to severe in nature, and occurs mostly in patients without chronic pain before surgery., (Copyright © 2024 American Society of Anesthesiologists.

Background: A holistic approach to emergency care treatment planning is needed to ensure that patients' preferences are considered should their clinical condition deteriorate. To address this, emergency care and treatment plans (ECTPs) have been introduced. Little is known about their use in general practice., Aim: To find out GPs' experiences of, and views on, using ECTPs., Design & Setting: Online survey of GPs practising in England., Method: A total of 841 GPs were surveyed using the monthly online survey provided by medeConnect, a market research company., Results: Forty-one per cent of responders' practices used Recommended Summary Plan for Emergency Care and Treatment (ReSPECT) plans for ECTP, 8% used other ECTPs, and 51% used Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) forms. GPs were the predominant professional group completing ECTPs in the community. There was broad support for a wider range of community-based health and social care professionals being able to complete ECTPs. There was no system for reviewing ECTPs in 20% of responders' practices. When compared with using a DNACPR form, GPs using a ReSPECT form for ECTP were more comfortable having conversations about emergency care treatment with patients (odds ratio [OR] = 1.72, 95% confidence interval [CI] = 1.1 to 2.69) and family members (OR =1.85, 95% CI = 1.19 to 2.87)., Conclusion: The potential benefits and challenges of widening the pool of health and social care professionals initiating and/or completing the ECTP process needs consideration. ReSPECT plans appear to make GPs more comfortable with ECTP discussions, supporting their implementation. Practice-based systems for reviewing ECTP decisions should be strengthened., (Copyright © 2024, The Authors.)

The specialist voluntary sector plays a crucial role in supporting survivors of sexual violence. However, in England, short-term funding underpins the sector's financial stability. This article examines sector leaders' ways of coping, resisting and being affected by funding practices. Using the concept of edgework, we show how funding and commissioning dynamics push individuals to the edge of service sustainability, job satisfaction, and emotional well-being. We examine how these edges are "worked," for example, by circumventing and remolding the edge. We offer an original way to theorize participants, make visible the emotional toll of service precarity and offer suggestions for support., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The Recommended Summary Plan for Emergency Care and Treatment (ReSPECT) was launched in the UK in 2016. ReSPECT is designed to facilitate meaningful discussions between healthcare professionals, patients, and their relatives about preferences for treatment in future emergencies; however, no study has investigated patients' and relatives' experiences of ReSPECT in the community., Objectives: To explore how patients and relatives in community settings experience the ReSPECT process and engage with the completed form., Methods: Patients who had a ReSPECT form were identified through general practice surgeries in three areas in England; either patients or their relatives (where patients lacked capacity) were recruited. Semi-structured interviews were conducted, focusing on the participants' understandings and experiences of the ReSPECT process and form. Data were analysed using inductive thematic analysis., Results: Thirteen interviews took place (six with patients, four with relatives, three with patient and relative pairs). Four themes were developed: (1) ReSPECT records a patient's wishes, but is entangled in wider relationships; (2) healthcare professionals' framings of ReSPECT influence patients' and relatives' experiences; (3) patients and relatives perceive ReSPECT as a do-not-resuscitate or end-of-life form; (4) patients' and relatives' relationships with the ReSPECT form as a material object vary widely. Patients valued the opportunity to express their wishes and conceptualised ReSPECT as a process of caring for themselves and for their family members' emotional wellbeing. Participants who described their ReSPECT experiences positively said healthcare professionals clearly explained the ReSPECT process and form, allocated sufficient time for an open discussion of patients' preferences, and provided empathetic explanations of treatment recommendations. In cases where participants said healthcare professionals did not provide clear explanations or did not engage them in a conversation, experiences ranged from confusion about the form and how it would be used to lingering feelings of worry, upset, or being burdened with responsibility., Conclusions: When ReSPECT conversations involved an open discussion of patients' preferences, clear information about the ReSPECT process, and empathetic explanations of treatment recommendations, working with a healthcare professional to co-develop a record of treatment preferences and recommendations could be an empowering experience, providing patients and relatives with peace of mind., (© 2024.

Objectives: Despite significant investment in social prescribing in England over the last decade, we still do not know if it works, or how models of social prescribing fit within wider health and care policy and practice. This study explores current service delivery structures and assesses the feasibility of a national evaluation of the link worker model., Methods: Semi-structured interviews were conducted between May and September 2020, with 25 key informants from across social prescribing services in England. Participants included link workers, voluntary, community and social enterprise staff, and those involved in policy and decision-making for social prescribing services. Interview and workshop transcripts were analysed thematically, adopting a framework approach., Results: We found differences in how services are provided, including by individual link workers, and between organisations and regions. Standards, referral pathways, reporting, and monitoring structures differ or are lacking in voluntary services as compared to clinical services. People can self-refer to a link worker or be referred by a third party, but the lack of standardised processes generated confusion in both public and professional perceptions of the link worker model. We identified challenges in determining the appropriate outcomes and outcome measures needed to assess the impact of the link worker model., Conclusions: The current varied service delivery structures in England poses major challenges for a national impact evaluation. Any future rigorous evaluation needs to be underpinned with national standardised outcomes and process measures which promote uniform data collection., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Patients undergoing vascular procedures are prone to developing postoperative complications affecting their short‑term mortality. Prospective reports describing the incidence of long‑term complications after vascular surgery are lacking., Objectives: We aimed to describe the incidence of complications 1 year after vascular surgery and to evaluate an association between myocardial injury after noncardiac surgery (MINS) and 1‑year mortality., Patients and Methods: This is a substudy of a large prospective cohort study Vascular Events in Noncardiac Surgery Patients Cohort Evaluation (VISION). Recruitment took place in 28 centers across 14 countries from August 2007 to November 2013. We enrolled patients aged 45 years or older undergoing vascular surgery, receiving general or regional anesthesia, and hospitalized for at least 1 night postoperatively. Plasma cardiac troponin T concentration was measured before the surgery and on the first, second, and third postoperative day. The patients or their relatives were contacted 1 year after the procedure to assess the incidence of major postoperative complications., Results: We enrolled 2641 patients who underwent vascular surgery, 2534 (95.9%) of whom completed 1‑year follow‑up. Their mean (SD) age was 68.2 (9.8) years, and the cohort was predominantly male (77.5%). The most frequent 1‑year complications were myocardial infarction (224/2534, 8.8%), amputation (187/2534, 7.4%), and congestive heart failure (67/2534, 2.6%). The 1‑year mortality rate was 8.8% (223/2534). MINS occurred in 633 patients (24%) and was associated with an increased 1‑year mortality (hazard ratio, 2.82; 95% CI, 2.14-3.72; P <0.001)., Conclusions: The incidence of major postoperative complications after vascular surgery is high. The occurrence of MINS is associated with a nearly 3‑fold increase in 1‑year mortality.

A woman in her 50s developed iron deficiency anaemia. Her medical history included hypertension, asthma and remote postpartum pulmonary embolism. There was a strong family history of atherosclerosis. After receiving intravenous iron sucrose (500 mg), she developed vomiting and large-volume diarrhoea, followed by diaphoresis, back pain, haemoconcentration (haematocrit increase, 0.242 to 0.326), leucocytosis and platelet count decline. Myocardial infarction was ruled out and the truncal pain subsided. However, 2 days postdischarge, she was diagnosed with aortic intraluminal thrombus (ILT) with embolisation into the lower extremities. The limbs were salvaged by emergency embolectomies and fasciotomies. Acute aortic ILT is a rare disorder that has not been previously reported as a complication of parenteral iron therapy. We postulate that acute intravascular volume losses (vomiting and diarrhoea) with resulting haemoconcentration and catecholamine-associated platelet activation and consumption, in a patient with subclinical aortic atherosclerosis, triggered acute aortic ILT presenting as lower-limb ischaemia., Competing Interests: Competing interests: Competing interests: IO, MP and JAH have no conflicts to declare.

Objectives: To describe the use, characteristics and influence of lay consultants on treatment-seeking decisions of adults in slums of Nigeria., Design: Cross-sectional survey using a pre-piloted questionnaire., Settings: Two slum communities in Ibadan city, Nigeria., Participants: 480 adults within the working age group (18-64)., Results: Most respondents (400/480, 83.7%) spoke to at least one lay consultant during their last illness/health concern. In total, 683 lay consultants were contacted; all from personal networks such as family and friends. No respondent listed online network members or platforms. About nine in 10 persons spoke to a lay consultant about an illness/health concern without intending to seek any particular support. However, almost all (680/683, 97%) lay consultants who were contacted provided some form of support. Marital status (OR=1.92, 95% CI: 1.10 to 3.33) and perceiving that an illness or health concern had some effects on their daily activities (OR=3.25, 95% CI: 1.94 to 5.46) had a significant independent association with speaking to at least one lay consultant. Age had a significant independent association with having lay consultation networks comprising non-family members only (OR=0.95, 95% CI: 0.92 to 0.99) or mixed networks (family and non-family members) (OR=0.97, 95% CI: 0.95 to 0.99), rather than family-only networks. Network characteristics influenced individual treatment decisions as participants who contacted networks comprising non-family members only (OR=0.23, 95% CI: 0.08 to 0.67) and dispersed networks (combination of household, neighbourhood and distant network members) (OR=2.04, 95% CI: 1.02 to 4.09) were significantly more likely to use informal than formal healthcare, while controlling for individual characteristics., Conclusions: Health programmes in urban slums should consider engaging community members so, when consulted within their networks, they are able to deliver reliable information about health and treatment-seeking., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objectives: Heavy cannabis use has been associated with the development of acute myocardial infarction and stroke. The objective of this study was to determine if heavy, chronic cannabis use is associated with the development of acute limb ischemia (ALI) or critical limb ischemia (CLI)., Methods: We conducted a retrospective cohort study within the National Inpatient Sample (2006-2015). Patients without cannabis use disorder (CUD) were matched to patients with CUD in a 2:1 ratio using propensity scores. Our primary outcomes were incidence of ALI and CLI. Secondary outcomes included incidence of acute mesenteric ischemia (AMI), chronic mesenteric ischemia (CMI), frequency of open or endovascular interventions, length of stay, and total costs. Sensitivity analyses were performed with alternative models, including in the entire unmatched cohort with regression models utilizing survey weights to account for sampling methodology., Results: We identified a cohort of 46,297 857 unmatched patients. Patients with CUD in the unmatched cohort were younger, with less cardiovascular risk factors, but higher rates of smoking and substance abuse. The matched cohort included 824,856 patients with CUD and 1,610,497 controls. Those with CUD had a higher incidence of ALI (OR 1.20 95% CI: 1.04-1.38 P =.016). Following multiple sensitivity analyses, there was no robust association between CLI and CUD. We observed no robust association of CUD with AMI, CMI, procedures performed, frequency of amputation, costs, or total length of stay., Conclusions: Cannabis use disorder was associated with a significantly higher incidence of admission for acute limb ischemia. CUD was not associated with an increased risk of critical limb ischemia following sensitivity analysis. Given CUD is often seen in younger, less co-morbid patients it provides an important target for intervention in this population.

Objectives: Lay consultation is the process of discussing a symptom or an illness with lay social network members. This can have positive or negative consequences on health-seeking behaviours. Understanding how consultation with lay social networks works in informal urban settlements of low-income and middle-income countries (LMICs) is important to enable health and policy-makers to maximise its potential to aid healthcare delivery and minimise its negative impacts. This study explored the composition, content and consequences of lay consultation in informal urban settlements of LMICs., Design: Mixed-method systematic review., Data Sources: Six key public health and social science databases, Google Scholar and reference lists of included studies were searched for potential articles., Eligibility Criteria: Papers that described discussions with lay informal social network members during symptoms or illness experiences., Data Analysis and Synthesis: Quality assessment was done using the Mixed Methods Appraisal Tool. Data were analysed and synthesised using a stepwise thematic synthesis approach involving two steps: identifying themes within individual studies and synthesising themes across studies., Results: 13 studies were included in the synthesis. Across the studies, three main categories of networks consulted during illness: kin, non-kin associates and significant community groups. Of these, kin networks were the most commonly consulted. The content of lay consultations were: asking for suggestions, negotiating care-seeking decisions, seeking resources and non-disclosure due to personal or social reasons. Lay consultations positively and negatively impacted access to formal healthcare and adherence to medical advice., Conclusion: Lay consultation is mainly sought from social networks in immediate environments in informal urban settlements of LMICs. Policy-makers and practitioners need to utilise these networks as mediators of healthcare-seeking behaviours., Prospero Registration Number: CRD42020205196., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objective: To determine if virtual care with remote automated monitoring (RAM) technology versus standard care increases days alive at home among adults discharged after non-elective surgery during the covid-19 pandemic., Design: Multicentre randomised controlled trial., Setting: 8 acute care hospitals in Canada., Participants: 905 adults (≥40 years) who resided in areas with mobile phone coverage and were to be discharged from hospital after non-elective surgery were randomised either to virtual care and RAM (n=451) or to standard care (n=454). 903 participants (99.8%) completed the 31 day follow-up., Intervention: Participants in the experimental group received a tablet computer and RAM technology that measured blood pressure, heart rate, respiratory rate, oxygen saturation, temperature, and body weight. For 30 days the participants took daily biophysical measurements and photographs of their wound and interacted with nurses virtually. Participants in the standard care group received post-hospital discharge management according to the centre's usual care. Patients, healthcare providers, and data collectors were aware of patients' group allocations. Outcome adjudicators were blinded to group allocation., Main Outcome Measures: The primary outcome was days alive at home during 31 days of follow-up. The 12 secondary outcomes included acute hospital care, detection and correction of drug errors, and pain at 7, 15, and 30 days after randomisation., Results: All 905 participants (mean age 63.1 years) were analysed in the groups to which they were randomised. Days alive at home during 31 days of follow-up were 29.7 in the virtual care group and 29.5 in the standard care group: relative risk 1.01 (95% confidence interval 0.99 to 1.02); absolute difference 0.2% (95% confidence interval -0.5% to 0.9%). 99 participants (22.0%) in the virtual care group and 124 (27.3%) in the standard care group required acute hospital care: relative risk 0.80 (0.64 to 1.01); absolute difference 5.3% (-0.3% to 10.9%). More participants in the virtual care group than standard care group had a drug error detected (134 (29.7%) v 25 (5.5%); absolute difference 24.2%, 19.5% to 28.9%) and a drug error corrected (absolute difference 24.4%, 19.9% to 28.9%). Fewer participants in the virtual care group than standard care group reported pain at 7, 15, and 30 days after randomisation: absolute differences 13.9% (7.4% to 20.4%), 11.9% (5.1% to 18.7%), and 9.6% (2.9% to 16.3%), respectively. Beneficial effects proved substantially larger in centres with a higher rate of care escalation., Conclusion: Virtual care with RAM shows promise in improving outcomes important to patients and to optimal health system function., Trial Registration: ClinicalTrials.gov NCT04344665., Competing Interests: Competing interests: All authors have completed the ICMJE uniform disclosure form at http://www.icmje.org/disclosure-of-interest/ and declare: support from Roche, McMaster University, the Research Institute of St Joseph’s Healthcare Hamilton, Ottawa Hospital Academic Medical Association, Queen’s University, Hamilton Health Sciences, Kingston Health Sciences, London Health Sciences, St Joseph’s Healthcare Hamilton, the Ottawa Hospital, and the University of Alberta Hospital for the submitted work; a financial relationship with Cloud Diagnostics Canada for purchase of devices and data plans used in this trial; and a relationship with Cloud Diagnostics Canada, which undertook training sessions for virtual nurses and perioperative doctors and surgeons on how to use their technology., (© Author(s) (or their employer(s)) 2019.

Background: Most studies describing the outcomes after endovascular abdominal aortic aneurysm repair (EVAR) explantation have been from single, high-volume, centers. We performed a multicenter cross-Canadian study of outcomes after EVAR stent graft explantation. Our objectives were to describe the outcomes after late open conversion and EVAR graft explantation at various Canadian centers and the techniques and outcomes stratified by the indication for explant., Methods: The Canadian Vascular Surgery Research Group performed a retrospective multicenter study of all cases of EVAR graft explantation at participating centers from 2003 to 2018. Data were collected using a standardized, secure, online platform (RedCap [Research Electronic Data Capture]). Univariate statistical analysis was used to compare the techniques and outcomes stratified the indication for graft explantation., Results: Patient data from 111 EVAR explants collected from 13 participating centers were analyzed. The mean age at explantation was 74 years, the average aneurysm size was 7.5 cm, and 28% had had at least one instructions for use violation at EVAR. The average time between EVAR and explantation was 42.5 months. The most common indication for explantation was endoleak (n = 66; type Ia, 46; type Ib, 2; type II, 9; type III, 2; type V, 7), followed by infection in 20 patients; rupture in 18 patients (due to type Ia endoleak in 10 patients, type Ib in 1, type II in 1, type III in 2, and type V in 1), and graft thrombosis in 7 patients. The overall 30-day mortality was 11%, and 45% of the patients had experienced at least one major perioperative complication. Mortality was significantly greater for patients with rupture (33.3%) and those with infection (15%) compared with patients undergoing elective explantation for endoleak (4.5%; P = .003). The average center volume during the previous 15 years was 8 cases with a wide range (2-19 cases). A trend was seen toward greater mortality for patients treated at centers with fewer than eight cases compared with those with eight or more cases (19% vs 9%). However, the difference did not reach statistical significance (P = .23). Overall, 41% of patients had undergone at least one attempt at endovascular salvage before explantation, with the highest proportion among patients who had undergone EVAR explantation for endoleak (51%). Only 22% of patients with rupture had undergone an attempt at endovascular salvage before explantation., Conclusions: The performance of EVAR graft explantation has increasing in Canada. Patients who had undergone elective explantation for endoleak had lower mortality than those treated for either infection or rupture. Thus, patients with an indication for explanation should be offered surgery before symptoms or rupture has occurred. A trend was seen toward greater mortality for patients treated at centers with lower volumes., (Copyright © 2021 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

N-terminal pro B-type natriuretic peptide (NT-proBNP), a cardiac disease biomarker, has been demonstrated to be a strong independent predictor of cardiovascular events in patients without heart failure. Patients with peripheral arterial disease (PAD) are at high risk of cardiovascular events and death. In this study, we investigated levels of NT-proBNP in patients with PAD compared to non-PAD controls. A total of 355 patients were recruited from outpatient clinics at a tertiary care hospital network. Plasma NT-proBNP levels were quantified using protein multiplex. There were 279 patients with both clinical and diagnostic features of PAD and 76 control patients without PAD (non-PAD cohort). Compared with non-PAD patients, median (IQR) NT-proBNP levels in PAD patients were significantly higher (225 ng/L (120-363) vs 285 ng/L (188-425), p- value = 0.001, respectively). Regression analysis demonstrated that NT-proBNP remained significantly higher in patients with PAD relative to non-PAD despite adjusting for age, sex, hypercholesterolemia, smoking and hypertension [odds ratio = 1.28 (1.07-1.54), p-value <0.05]. Subgroup analysis showed elevated NT-proBNP levels in patients with PAD regardless of prior history of CHF, CAD, diabetes and hypercholesteremia (p-value <0.05). Finally, spearmen's correlation analysis demonstrated a negative correlation between NT-proBNP and ABI (ρ = -0.242; p-value < 0.001). In conclusion, our data shows that patients with PAD in an ambulatory care setting have elevated levels of NT-proBNP compared to non-PAD patients in the absence of cardiac symptoms., Competing Interests: Lastly, Dr. John Eikelboom reports consulting fees/honoraria and/or grant support from Astra-Zeneca, Bayer Boehringer-Ingelheim, Bristol-Myer-Squibb/Pfizer, Daiichi-Sankyo, Eli-Lilly, Glaxo-Smith-Kline, Pfizer, Janssen, Sanofi-Aventis, Servier.

Background: Following severe limb ischemia requiring urgent/emergent revascularization, peripheral arterial disease patients suffer a high risk of recurrent atherothrombosis., Methods: Patients discharged from Hamilton General Hospital (Hamilton, Ontario) between April 2016 and September 2017 following severe limb ischemia requiring urgent/emergent revascularization were identified via the Local Health Integration Network CorHealth database, with supplemental information from chart review., Results: A total of 158 patients admitted for urgent/emergent revascularization were identified (148 alive at discharge). Among patients without a pre-existing indication for anticoagulation, 38.8% ( n  = 47) were discharged on single-antiplatelet therapy, 27.3% ( n  = 33) on dual-antiplatelet therapy, 19.8% ( n  = 24) on anticoagulants plus antiplatelet therapy, 6.6% ( n  = 8) on anticoagulants alone, and 2.6% ( n  = 3) on unknown therapy. Patients who received angioplasty with stenting were more likely be discharged on dual-antiplatelet therapy (hazard ratio [HR]: 7.14; 95% confidence interval [CI]: 2.87-17.76; P < 0.01); patients who received an embolectomy/thrombectomy were more likely be discharged on an anticoagulant alone (HR: 2.61; 95% CI: 1.00-6.81; P  = 0.049); and patients who received peripheral bypass grafting were more likely be discharged on single-antiplatelet therapy (HR: 2.28; 95% CI: 1.11-4.69; P  = 0.024). Neither statins (60.8% vs 56.3%; P  = 0.23) nor renin-angiotensin-aldosterone system inhibitors (48.7% vs 50.6%; P  = 0.58) were prescribed at higher rates at discharge, compared with the rate at admission., Conclusions: Substantial heterogeneity exists in antithrombotic prescription following urgent/emergent revascularization. No intensification of non-antithrombotic vascular protective medications occurred during hospitalization. Clinical trials and health system interventions to optimize medical therapy in peripheral arterial disease patients are urgently needed., (© 2021 The Authors.)

Plasma levels of fatty acid binding protein 3 (pFABP3) are elevated in patients with peripheral artery disease (PAD). Since the kidney filters FABP3 from circulation, we investigated whether urinary fatty acid binding protein 3 (uFABP3) is associated with PAD, and also explored its potential as a diagnostic biomarker for this disease state. A total of 130 patients were recruited from outpatient clinics at St. Michael's Hospital, comprising of 65 patients with PAD and 65 patients without PAD (non-PAD). Levels of uFABP3 normalized for urine creatinine (uFABP3/uCr) were 1.7-folds higher in patients with PAD [median (IQR) 4.41 (2.79-8.08)] compared with non-PAD controls [median (IQR) 2.49 (1.78-3.12), p-value = 0.001]. Subgroup analysis demonstrated no significant effect of cardiovascular risk factors (age, sex, hypertension, hypercholesteremia, diabetes and smoking) on uFABP3/uCr in both PAD and non-PAD patients. Spearmen correlation studies demonstrated a significant negative correlation between uFABP3/uCr and ABI (ρ = - 0.436; p-value = 0.001). Regression analysis demonstrated that uFABP3/Cr levels were associated with PAD independently of age, sex, hypercholesterolemia, smoking, prior history of coronary arterial disease and Estimated Glomerular Filtration rate (eGFR) [odds ratio: 2.34 (95% confidence interval: 1.47-3.75) p-value < 0.001]. Lastly, receiver operator curve (ROC) analysis demonstrated unadjusted area under the curve (AUC) for uFABP3/Cr of 0.79, which improved to 0.86 after adjusting for eGFR, age, hypercholesteremia, smoking and diabetes. In conclusion, our results demonstrate a strong association between uFABP3/Cr and PAD and suggest the potential of uFABP3/Cr in identifying patients with PAD.

Background: After nonelective (i.e., semiurgent, urgent and emergent) surgeries, patients discharged from hospitals are at risk of readmissions, emergency department visits or death. During the coronavirus disease 2019 (COVID-19) pandemic, we are undertaking the Post Discharge after Surgery Virtual Care with Remote Automated Monitoring Technology (PVC-RAM) trial to determine if virtual care with remote automated monitoring (RAM) compared with standard care will increase the number of days adult patients remain alive at home after being discharged following nonelective surgery., Methods: We are conducting a randomized controlled trial in which 900 adults who are being discharged after nonelective surgery from 8 Canadian hospitals are randomly assigned to receive virtual care with RAM or standard care. Outcome adjudicators are masked to group allocations. Patients in the experimental group learn how to use the study's tablet computer and RAM technology, which will measure their vital signs. For 30 days, patients take daily biophysical measurements and complete a recovery survey. Patients interact with nurses via the cellular modem-enabled tablet, who escalate care to preassigned and available physicians if RAM measurements exceed predetermined thresholds, patients report symptoms, a medication error is identified or the nurses have concerns they cannot resolve. The primary outcome is number of days alive at home during the 30 days after randomization., Interpretation: This trial will inform management of patients after discharge following surgery in the COVID-19 pandemic and offer insights for management of patients who undergo nonelective surgery in a nonpandemic setting. Knowledge dissemination will be supported through an online multimedia resource centre, policy briefs, presentations, peer-reviewed journal publications and media engagement., Trial Registration: ClinicalTrials.gov, no.

Patients with peripheral artery disease who undergo urgent or emergent lower extremity revascularization have the highest risk of major adverse cardiac and limb events. Although available evidence suggests that antithrombotic therapy reduces this risk, optimal antithrombotic therapy is unclear. In this report, we aim to describe current practice patterns for use of antithrombotic therapies after urgent/emergent peripheral artery revascularization. A self-administered online survey was distributed to all active vascular surgeons registered through the Canadian Society of Vascular Surgery (n = 149) between March 19 and April 29, 2019. The overall response rate was 53% (79/149). More than half of the respondents use a medical specialist service in aiding decision-making (52% (95% confidence interval [CI], 40.9%-63.0%). When concerned for high rethrombosis risk, respondents most commonly favoured initiation of either aspirin plus full dose anticoagulation (60% [95% CI, 49.2%-70.8%]) or dual antiplatelet therapy (58% (95% CI, 47.1%-68.9%]). Intraoperative findings and patient characteristics prompting concern for high rethrombosis risk include residual proximal/distal occlusive disease (75% [95% CI, 65.5%-84.5%]), poor-quality venous conduit (76% [95% CI, 66.6%-85.4%]), distal/infrapopliteal synthetic conduit (77% [95% CI, 67.7%-86.3%]), and history of multiple previous failed vascular interventions (98% [95% CI, 94.9%-100%]). More than 90% of respondents believe significant uncertainty exists in antithrombotic decision-making after urgent/emergent peripheral revascularization. Substantial uncertainty exists regarding antithrombotic therapy after urgent/emergent revascularization. In patients at high perceived rethrombosis risk, vascular surgeons preferentially choose aspirin with full-dose anticoagulation or dual antiplatelet therapy. Because of the clinical uncertainty in this domain, trials to determine optimal antithrombotic therapy in this high-risk population are required., (Copyright © 2020 Canadian Cardiovascular Society.

The decommissioning of a health-care service is invariably a highly complex and contentious process which faces many implementation challenges. There has been little specific theorisation of this phenomena, although insights can be transferred from wider literatures on policy implementation and change processes. In this paper, we present findings from empirical case studies of three decommissioning processes initiated in the English National Health Service. We apply Levine's (1979, Public Administration Review, 39(2), 179-183) typology of decommissioning drivers and insights from the empirical literature on pluralistic health-care contexts, complex change processes and institutional constraints. Data include interviews, non-participant observation and documents analysis. Alongside familiar patterns of pluralism and political partisanship, our results suggest the important role played by institutional factors in determining the outcome of decommissioning processes and in particular the prior requirement of political vulnerability for services to be successfully closed. Factors linked to the extent of such vulnerability include the scale of the proposed changes and extent to which they are supported at the macrolevel., (© 2021 Foundation for the Sociology of Health & Illness.)

Objective: Diabetic foot ulcer, which often leads to lower limb amputation, is a devastating complication of diabetes that is a major burden on patients and the healthcare system. The main objective of this study is to determine the economic burden of diabetic foot ulcer-related care., Methods: We conducted a multicenter study of all diabetic foot ulcer patients admitted to general internal medicine wards at seven hospitals in the Greater Toronto Area, Canada from 2010 to 2015, using the GEMINI database. We compared the mean costs of care per patient for diabetic foot ulcer-related admissions, admissions for other diabetes-related complications, and admissions for the top five most costly general internal medicine conditions, using the Ontario Case Costing Initiative. Regression models were used to determine adjusted estimates of cost per patient. Propensity-score matched analyses were performed as sensitivity analyses., Results: Our study cohort comprised of 557 diabetic foot ulcer patients; 2939 non-diabetic foot ulcer diabetes patients; and 23,656 patients with the top 5 most costly general internal medicine conditions. Diabetic foot ulcer admissions incurred the highest mean cost per patient ($22,754) when compared to admissions with non-diabetic foot ulcer diabetes ($8,350) and the top five most costly conditions ($10,169). Using adjusted linear regression, diabetic foot ulcer admissions demonstrated a 49.6% greater mean cost of care than non-diabetic foot ulcer-related diabetes admissions (95% CI 1.14-1.58), and a 25.6% greater mean cost than the top five most costly conditions (95% CI 1.17-1.34). Propensity-scored matched analyses confirmed these results., Conclusion: Diabetic foot ulcer patients incur significantly higher costs of care when compared to admissions with non-diabetic foot ulcer-related diabetes patients, and the top five most costly general internal medicine conditions.

Objective: In vascular and cardiac surgery, the ability to maintain haemostasis and seal haemorrhagic tissues is key. Fibrin and thrombin based sealants were introduced as a means to prevent or halt bleeding during surgery. Whether fibrin and thrombin sealants affect surgical outcomes is poorly established. A systematic review and meta-analysis was performed to examine the impact of fibrin or thrombin sealants on patient outcomes in vascular and cardiac surgery., Data Sources: Cochrane CENTRAL, Embase, and MEDLINE, as well as trial registries, conference abstracts, and reference lists of included articles were searched from inception to December 2019., Review Methods: Studies comparing the use of fibrin or thrombin sealant with either an active (other haemostatic methods) or standard surgical haemostatic control in vascular and cardiac surgery were searched for. The Cochrane risk of bias tool and the ROBINS-I tool (Risk Of Bias In Non-randomised Studies - of Interventions) were used to assess the risk of bias of the included randomised and non-randomised studies; quality of evidence was assessed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Two reviewers screened studies, assessed risk of bias, and extracted data independently and in duplicate. Data from included trials were pooled using a random effects model., Results: Twenty-one studies (n = 7 622 patients) were included: 13 randomised controlled trials (RCTs), five retrospective, and three prospective cohort studies. Meta-analysis of the RCTs showed a statistically significant decrease in the volume of blood lost (mean difference 120.7 mL, in favour of sealant use [95% confidence interval {CI} -150.6 - -90.7; p < .001], moderate quality). Time to haemostasis was also shown to be reduced in patients receiving sealant (mean difference -2.5 minutes [95% CI -4.0 - -1.1; p < .001], low quality). Post-operative blood transfusions, re-operation due to bleeding, and 30 day mortality were not significantly different for either RCTs or observational data., Conclusion: The use of fibrin and thrombin sealants confers a statistically significant but clinically small reduction in blood loss and time to haemostasis; it does not reduce blood transfusion. These Results may support selective rather than routine use of fibrin and thrombin sealants in vascular and cardiac surgery., Competing Interests: Conflicts of interest None., (Copyright © 2020 European Society for Vascular Surgery.

Background: With increasing healthcare costs and the emergence of new technologies in vascular surgery, economic evaluations play a critical role in informing decision-making that optimizes patient outcomes while minimizing per capita costs. The objective of this systematic review is to describe all English published economic evaluations in vascular surgery and to identify any significant gaps in the literature., Methods: We conducted a comprehensive English literature review of EMBASE, MEDLINE, The Cochrane Library, Ovid Health Star, and Business Source Complete from inception until December 1, 2018. Two independent reviewers screened articles for eligibility using predetermined inclusion criteria and subsequently extracted data. Articles were included if they compared 2 or more vascular surgery interventions using either a partial economic evaluation (cost analysis) or full economic evaluation (cost-utility, cost-benefit, and/or cost-effectiveness analysis). Data extracted included publishing journal, date of publication, country of origin of authors, type of economic evaluation, and domain of vascular surgery., Results: A total of 234 papers were included in the analysis. The majority of the papers included only a cost analysis (183, 78%), and there were only 51 papers that conducted a full economic analysis (22%). The 51 papers conducted a total of 69 economic analyses. This consisted of 32 cost-effectiveness analyses, 29 cost-utility analyses, and 8 cost-benefit analyses. The most common domains studied were aneurysmal disease (89, 38%) and peripheral vascular disease (50, 21%). Economic evaluations were commonly published in the Journal of Vascular Surgery (83, 35%) and Annals of Vascular Surgery (32, 14%), with most study authors located in the United States (127, 54%). There was a trend of economic evaluations being published more frequently in recent years., Conclusions: The majority of vascular surgery economic evaluations used only a cost analysis, rather than a full economic evaluation, which may not be ideal in pursuing interventions that simultaneously optimize cost and patient outcomes. The literature is lacking in full economic evaluations-a trend persistent in other surgical specialties-and there is a need for full economic evaluations to be conducted in the field of vascular surgery., (Crown Copyright © 2020.

Background: Integrated care has the potential to ease the increasing pressures faced by health and social care systems, however, challenges around measuring the benefits for providers, patients, and service users remain. This paper explores stakeholders' views on the benefits of integrated care and approaches to measuring the integration of health and social care., Methods: Twenty-five semi-structured qualitative interviews were conducted with professional stakeholders (n = 19) and patient representatives (n = 6). Interviews focused on the benefits of integrated care and how it should be evaluated. Data was analysed using framework analysis., Results: Three overarching themes emerged from the data: (1) integrated care and its benefits, with stakeholders defining it primarily from the patient's perspective; (2) potential measures for assessing the benefits of integration in terms of system effects, patient experiences, and patient outcomes; and (3) broader considerations around the assessment of integrated care, including the use of qualitative methods., Conclusions: There was consensus among stakeholders that patient experiences and outcomes are the best measures of integration, and that the main measures currently used to assess integration do not directly assess patient benefits. Validated health status measures are readily available, however, a substantial shift in practices is required before their use becomes commonplace.

Background: As people are living longer with higher incidences of long-term health conditions, there is a move towards greater integration of care, including integration of health and social care services. Integrated care needs to be comprehensively and systematically evaluated if it is to be implemented widely. We performed a systematic review of reviews to identify measures which have been used to assess integrated care across health and social care services for people living with long-term health conditions., Methods: Four electronic databases (PUBMED; MEDLINE; EMBASE; Cochrane library of systematic reviews) were searched in August 2018 for relevant reviews evaluating the integration of health and social care between 1998 and 2018. Articles were assessed according to apriori eligibility criteria. A data extraction form was utilised to collate the identified measures into five categories., Results: Of the 18 articles included, system outcomes and process measures were most frequently identified (15 articles each). Patient or carer reported outcomes were identified in 13 articles while health outcomes were reported in 12 articles. Structural measures were reported in nine articles. Challenges to measuring integration included the identification of a wide range of potential impacts of integration, difficulties in comparing findings due to differences in study design and heterogeneity of types of outcomes, and a need for appropriate, robust measurement tools., Conclusions: Our review revealed no shortage of measures for assessing the structures, processes and outcomes of integrated care. The very large number of available measures and infrequent use of any common set make comparisons between schemes more difficult. The promotion of core measurement sets and stakeholder consultation would advance measurement in this area.

Objective: Patients are increasingly referring to the Internet after a diagnosis of vascular disease. This study was performed to quantitatively define the accuracy and reliability of information on YouTube regarding abdominal aortic aneurysms (AAA)., Methods: A systematic search of YouTube was conducted using multiple AAA-specific keywords. The default YouTube search setting of "relevance" was used to replicate an average search attempt, and the first 50 results from each keyword search were reviewed and analyzed by two independent reviewers. Descriptive characteristics, Journal of the American Medical Association Score, modified DISCERN score, Video Power Index, and a novel scoring system for the management of AAAs, the AAA-Specific Score (AAASS), were used to record data. Inter-rater agreement was analyzed using intraclass correlation coefficient estimates and the Kruskal-Wallis test was used for intergroup comparisons., Results: Fifty-one videos were included for analysis. The mean Journal of the American Medical Association Score, DISCERN, and AAASS values among videos were 1.74/4.00 (standard deviation [SD], 0.84), 2.37/5.00 (SD, 0.97), and 6.63/20.00 (SD, 3.23), respectively. Of all the included videos, 78% were educational in nature, 14% were patient testimonials, and 8% were news programs. Based on the AAASS, the majority of analyzed videos fell into the poor category (41%), followed next by the very poor (31%), moderately useful (25%), very useful (2%), and exceptional (0%) categories. Videos by nonphysicians were significantly more popular (P < .05) than vascular surgeon sources., Conclusions: Although variable in source and content, the completeness and reliability of information offered on YouTube for AAA diagnosis and treatment is poor. Patients watching YouTube for information on their AAA diagnosis are receiving an incomplete and perhaps misleading picture of available diagnostic and treatment options. Given that vascular surgeons are likely to be affected by unrealistic treatment expectations from patients accessing online materials regarding AAA, it is important to acknowledge the nature of content on these platforms., (Copyright © 2019 Society for Vascular Surgery.

Introduction: The voluntary sector provides a range of specialist services to survivors of sexual violence, many of which have evolved from grass roots organisations responding to unmet local needs. However, the evidence base is poor in terms of what services are provided to which groups of survivors, how voluntary sector specialist (VSS) services are organised and delivered and how they are commissioned. This will be the first national study on the role of the voluntary sector in supporting survivors in England., Methods and Analysis: This study uses an explanatory sequential naturalistic mixed-methods design with two stages. For stage 1, two national surveys of providers' and commissioners' views on designing and delivering VSS services will facilitate detailed mapping of service provision and commissioning in order to create a taxonomy of VSS services. Variations in the national picture will then be explored in stage 2 through four in-depth, qualitative case studies using the critical incident technique to explain the observed variations and understand the key contextual factors which influence service provision. Drawing on theory about the distinctive service contribution of the voluntary sector, survivors will be involved as co-researchers and will play a central role in data collection and interpretation., Ethics and Dissemination: Ethical approval has been granted by the University of Birmingham research ethics committee for stage 1 of the project. In line with the sequential and co-produced study design, further applications for ethical review will be made in due course. Dissemination activities will include case study and end-of-project workshops; good practice guides; a policy briefing; project report; bitesize findings; webinars; academic articles and conference presentations. The project will generate evidence about what survivors want from and value about services and new understanding about how VSS services should be commissioned and provided to support survivors to thrive in the long term., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Objective: The Society for Vascular Surgery's Annual Meeting acts as a means of disseminating research findings among vascular surgeons through the presentation of research abstracts. Following presentation at the meeting, research is often compiled into a full-text manuscript and submitted to a peer-reviewed journal. However, not all abstracts accepted to the Vascular Annual Meeting (VAM) eventually have a corresponding full-text publication. The objectives of this study were to establish the publication rate of abstracts presented between 2012 and 2015 to the VAM and to identify factors correlating with publication status., Methods: Abstracts presented at the VAM were available through the Journal of Vascular Surgery. Data extracted from eligible abstracts included level of evidence according to the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence scheme, type of study (prognostic, therapeutic/harm, diagnostic), sample size, and status of outcome (positive, negative, or descriptive findings). Publication status of the abstracts was determined through a comprehensive literature review of PubMed (MEDLINE), Ovid (MEDLINE), and Embase. A multivariable logistic regression was conducted to determine factors correlating with publication status., Results: The publication rate during the study period was 43.0% with a median time to publication of 9 months, with 412 of the 958 abstracts having a corresponding full-text publication in 48 journals with weighted mean impact factor of 3.40. Eleven journals collectively published 372 (90.3%) of the articles, with the Journal of Vascular Surgery publishing 280 (68.0%) of the manuscripts. Our logistic regression model demonstrated that factors positively affecting publication status were a positive status of outcome (odds ratio, 2.59; 95% confidence interval, 1.56-4.28) and a logarithmic increase in the sample size of the study (odds ratio, 1.35; 95% confidence interval, 1.13-1.60). In addition, studies with a corresponding full-text publication had a greater median sample size (250) compared with those without one (143; P < .001)., Conclusions: From 2012 to 2015, 43.0% of VAM abstracts had a corresponding full-text publication, with greater sample size and a positive status of outcome positively correlating with likelihood of publication. Studies with negative findings made up a small proportion of conference abstracts (9.6%) and were the least likely to be published. Given the relatively small size of the specialty of vascular surgery, it may be particularly important to be mindful of publication bias. It may be worthwhile to give additional consideration to acceptance of abstracts or publication of studies with negative results that meaningfully contribute to the literature., (Crown Copyright © 2018.
