Background: Cardiovascular disease (CVD) is the leading cause of non‐cancer death in cancer survivors, but the risk of CVD varies between cancers. Objectives: To synthesise available evidence on patterns and magnitude of CVD mortality risk. Methods: A systematic search of Medline (OVID), CINAHL and Scopus databases from 01‐January‐2000 to 16‐July‐2023 of studies of people with cancer, reporting CVD mortality in cancer population compared with a reference population (e.g. general population) as standardised mortality ratios (SMR). Meta‐analysis of SMRs across cancer and CVD types were pooled using a random‐effects model to allow for heterogeneity of the true effect size across studies. Results: We identified 136 studies from 16 countries. Sample sizes ranged from 157 to 7,529,481. The majority (n = 98; 72%) were conducted in the United States, followed by Europe (n = 22; 16%). The most common cancers studied were gastrointestinal (n = 34 studies), haematological (n = 31) and breast (n = 29). A total of 876 CVD SMRs were extracted across diverse CVD conditions. Of those, the majority (535; 61%) indicated an increased risk of CVD death (SMR >1), 109 (12%) a lower risk of CVD death (SMR <1) and 232 (27%) an equivalent risk (95% CI of SMR included 1) compared to the general population. The meta‐analysis of all reported SMRs showed an increased risk of CVD death (SMR = 1.55, 95% CI = 1.40–1.72) in cancer survivors compared with the general population. The SMR varied between CVD conditions and ranged from 1.36 (95% CI = 1.29–1.44) for heart diseases to 1.56 (95% CI = 1.39–1.76) for cerebrovascular diseases. SMR varied across cancer types, ranging from 1.14 (95% CI = 1.04–1.25) for testicular/germ cell tumours to 2.82 (95% CI = 2.20–3.63) for brain/central nervous system tumours. Conclusions: Cancer survivors are at increased risk of premature CVD mortality compared to the general population, but the risk varies by cancer type and CVD. Future research should focus on understanding mechanisms behind the increased CVD risk to develop appropriate interventions. [ABSTRACT FROM AUTHOR]

Objectives: To investigate causes of death of people with cancer alive five years after diagnosis, and to compare mortality rates for this group with those of the general population. Design, setting, participants: Retrospective cohort study; analysis of South Australian Cancer Registry data for all people diagnosed with cancer during 1990–1999 and alive five years after diagnosis, with follow‐up to 31 December 2016. Main outcome measures: All‐cause and cancer cause‐specific mortality, by cancer diagnosis; standardised mortality ratios (study group v SA general population) by sex, age at diagnosis, follow‐up period, and index cancer. Results: Of 32 646 people with cancer alive five years after diagnosis, 30 309 were of European background (93%) and 16 400 were males (50%); the mean age at diagnosis was 60.3 years (SD, 15.7 years). The median follow‐up time was 17 years (IQR, 11–21 years); 17 268 deaths were recorded (53% of patients; mean age, 80.6 years; SD, 11.4 years): 7845 attributed to cancer (45% of deaths) and 9423 attributed to non‐cancer causes (55%). Ischaemic heart disease was the leading cause of death (2393 deaths), followed by prostate cancer (1424), cerebrovascular disease (1175), and breast cancer (1118). The overall standardised mortality ratio (adjusted for age, sex, and year of diagnosis) was 1.24 (95% CI, 1.22–1.25). The cumulative number of cardiovascular deaths exceeded that of cancer cause‐specific deaths from 13 years after cancer diagnosis. Conclusions: Mortality among people with cancer who are alive at least five years after diagnosis was higher than for the general population, particularly cardiovascular disease‐related mortality. Survivorship care should include early recognition and management of risk factors for cardiovascular disease. [ABSTRACT FROM AUTHOR]

One approach to manage people with behaviours of concern including agitated or aggressive behaviours in health care settings is through the use of fast‐acting medication, called chemical restraint. Such management often needs to be delivered in crisis situations to patients who are at risk of harm to themselves or others. This paper summarizes the available evidence on the effectiveness and safety of chemical restraint from 21 randomized controlled trials (RCTs) involving 3788 patients. The RCTs were of moderate to high quality and were conducted in pre‐hospital, hospital emergency department, or ward settings. Drugs used in chemical restraint included olanzapine, haloperidol, droperidol, risperidol, flunitrazepam, midazolam, promethazine, ziprasidone, sodium valproate, or lorazepam. There was limited comparability between studies in drug choice, combination, dose, method of administration (oral, intramuscular, or intravenous drip), or timing of repeat administrations. There were 31 outcome measures, which were inconsistently reported. They included subjective measures of behaviours, direct measures of treatment effect (time to calm; time to sleep), indirect measures of agitation (staff or patient injuries, duration of agitative or aggressive episodes, subsequent violent episodes), and adverse events. The most common were time to calm and adverse events. There was little clarity about the superiority of any chemical method of managing behaviours of concern exhibited by patients in Emergency Departments or acute mental health settings. Not only is more targeted research essential, but best practice recommendations for such situations requires integrating expert input into the current evidence base. [ABSTRACT FROM AUTHOR]

Context: The use of peer support as a faculty development technique to improve clinical teaching is uncommon in medical education, despite the benefits of situating learning in the workplace. The authors therefore conducted a broad search seeking theoretical and empirical literature describing peer support strategies for clinical teachers in health care workplaces. This included descriptive and non‐experimental studies that are often excluded from reviews. The review aimed to identify and assess existing initiatives and to synthesise key challenges and benefits. Methods: An integrative literature review was undertaken (2004–2017), based on searches of eight international electronic databases and targeted manual searches. Key concepts, elements and models were mapped using an iterative, constant comparative method. An evaluative framework, drawing on previous research, informed conclusions regarding the quality of evidence. Results: From a pool of 5735 papers, 34 met the inclusion criteria. The majority referred to studies conducted in the USA (59%) and in the medical profession (71%). Analysis revealed a trend towards using a collaborative model (56%), voluntary participation (59%), and direct workplace observation by a peer clinician (68%). Design features of the peer support strategy were commonly reported (65%), with half providing outcome measures (56%). Few papers reported on process evaluation (15%) or evidence of programme sustainability (15%). Despite logistical and time‐associated challenges, benefits accrued to individuals and the workplace, and included improved teaching practices. Embedding the peer support strategy into routine organisational practice proved effective. Conclusions: The results indicated that a workplace‐based peer support model is an acceptable and effective faculty development strategy for health care clinical teachers. Conceptualising workplace‐based peer support via a sociocultural model that acknowledges the significance of educational design, peers as collaborators and the importance of workplace context and culture is emphasised. Future research should focus on clarification studies informed by contemporary models of faculty development, in which factors impacting the health care workplace are considered. By reviewing the literature, Campbell et al. highlight how collaborative relationships and workplace connections with peers offer an under‐utilized resource for effectively improving teaching expertise.

Background: Searching for topics within large biomedical databases can be challenging, especially when topics are complex, diffuse, emerging or lack definitional clarity. Experimentally derived topic search filters offer a reliable solution to effective retrieval; however, their number and range of subject foci remain unknown. Objectives: This systematic scoping review aims to identify and describe available experimentally developed topic search filters. Methods: Reports on topic search filter development (1990‐) were sought using grey literature sources and 15 databases. Reports describing the conception and prospective development of a database‐specific topic search and including an objectively measured estimate of its performance ('sensitivity') were included. Results: Fifty‐four reports met inclusion criteria. Data were extracted and thematically synthesised to describe the characteristics of 58 topic search filters. Discussion: Topic search filters are proliferating and cover a wide range of subjects. Filter reports, however, often lack clear definitions of concepts and topic scope to guide users. Without standardised terminology, filters are challenging to find. Information specialists may benefit from a centralised topic filter repository and appraisal checklists to facilitate quality assessment. Conclusion: Findings will help information specialists identify existing topic search filters and assist filter developers to build on current knowledge in the field. [ABSTRACT FROM AUTHOR]

Objectives Health professionals must be able to search competently for evidence to support practice. We sought to understand how palliative care clinicians construct searches for palliative care literature in PubMed, to quantify search efficacy in retrieving a set of relevant articles and to compare performance against a Palliative CareSearch Filter ( PCSF). Methods Included studies from palliative care systematic reviews formed a test set. Palliative care clinicians ( n = 37) completed a search task using PubMed. Individual clinician searches were reconstructed in PubMed and combined with the test set to calculate retrieval sensitivity. PCSF performance in the test set was also determined. Results Many clinicians struggled to create useful searches. Twelve used a single search term, 17 narrowed the search inappropriately and 8 confused Boolean operators. The mean number of test set citations ( n = 663) retrieved was 166 ( SD = 188), or 25% although 76% of clinicians believed they would find more than 50% of the articles. Only 8 participants (22%) achieved this. Correlations between retrieval and PubMed confidence (r = 0.13) or frequency of use ( r = −0.18) were weak. Conclusions Many palliative care clinicians search PubMed ineffectively. Targeted skills training and PCSF promotion may improve evidence retrieval. [ABSTRACT FROM AUTHOR]

Background The evidence base developed by, and relevant to, primary health care (PHC) is rapidly increasing. With the wealth of literature available, searchers trying to find PHC-specific citations can feel overwhelmed. Objectives Flinders Filters and the Primary Health Care Research & Information Service collaborated to develop a search filter enabling efficient and effective retrieval of relevant PHC literature. Methods Stage 1 involved developing a PHC Search Filter in the OvidSP Medline platform using a rigorous experimental methodology. The search filter was then translated for Web-based 'one-click searching' in PubMed during Stage 2. Stage 3 involved planning and implementing a mixed-methods evaluation. Results The search filter sensitivity was 77.0% with a post hoc relevance assessment of 78.3%. Four months after its launch, a mixed-methods study evaluated the PHC Search Filter. With 90 respondents, analysis of data from the online survey demonstrated overarching benefits, a positive response to the tool and directions for further refinement of the PHC Search Filter. Discussion Designing the PHC Search Filter followed an established method that ensures the tool offers a validated search strategy. Evaluation results suggest that the PHC Search Filter is a useful tool that is easy to navigate. Challenges for the Filter relate to access to full text articles, while challenges for the evaluation relate to the small sample size. Conclusions The PHC Search Filter reduces the burden associated with literature searching, increases the value of the results that are received and provides a useful resource to improve the likelihood of incorporating relevant evidence into policy and practice.
