Aim: We studied the association between neighbourhood material deprivation, a metric estimating inability to attain basic material needs, with outcomes and processes of care among incident heart failure patients in a universal healthcare system. Methods and results: In a population‐based retrospective study (2007–2019), we examined the association of material deprivation with 1‐year all‐cause mortality, cause‐specific hospitalization, and 90‐day processes of care. Using cause‐specific hazards regression, we quantified the relative rate of events after multiple covariate adjustment, stratifying by age ≤65 or ≥66 years. Among 395 763 patients (median age 76 [interquartile range 66–84] years, 47% women), there was significant interaction between age and deprivation quintile for mortality/hospitalization outcomes (p ≤ 0.001). Younger residents (age ≤65 years) of the most versus least deprived neighbourhoods had higher hazards of all‐cause death (hazard ratio [HR] 1.19, 95% confidence interval [CI] 1.10–1.29]) and cardiovascular hospitalization (HR 1.29 [95% CI 1.19–1.39]). Older individuals (≥66 years) in the most deprived neighbourhoods had significantly higher hazard of death (HR 1.11 [95% CI 1.08–1.14]) and cardiovascular hospitalization (HR 1.13 [95% CI 1.09–1.18]) compared to the least deprived. The magnitude of the association between deprivation and outcomes was amplified in the younger compared to the older age group. More deprived individuals in both age groups had a lower hazard of cardiology visits and advanced cardiac imaging (all p < 0.001), while the most deprived of younger ages were less likely to undergo implantable cardioverter‐defibrillator/cardiac resynchronization therapy‐pacemaker implantation (p = 0.023), compared to the least deprived. Conclusion: Patients with newly‐diagnosed heart failure residing in the most deprived neighbourhoods had worse outcomes and reduced access to care than those less deprived. [ABSTRACT FROM AUTHOR]

Background: Virtual care quickly became of crucial importance to health systems around the world during the COVID-19 pandemic. Despite the potential of virtual care to enhance access for some communities, the scale and pace at which services were virtualized did not leave many organizations with sufficient time and resources to ensure optimal and equitable delivery of care for everyone. The objective of this paper is to outline the experiences of health care organizations rapidly implementing virtual care during the first wave of the COVID-19 pandemic and examine whether and how health equity was considered. Methods: We used an exploratory, multiple case study approach involving four health and social service organizations providing virtual care services to structurally marginalized communities in the province of Ontario, Canada. We conducted semi-structured qualitative interviews with providers, managers, and patients to understand the challenges experienced by organizations and the strategies put in place to support health equity during the rapid virtualization of care. Thirty-eight interviews were thematically analyzed using rapid analytic techniques. Results: Organizations experienced challenges related to infrastructure availability, digital health literacy, culturally appropriate approaches, capacity for health equity, and virtual care suitability. Strategies to support health equity included the provision of blended models of care, creation of volunteer and staff support teams, participation in community engagement and outreach, and securement of infrastructure for clients. We put our findings into the context of an existing framework conceptualizing access to health care and expand on what this means for equitable access to virtual care for structurally marginalized communities. Conclusion: This paper highlights the need to pay greater attention to the role of health equity in virtual care delivery and situate that conversation around existing inequitable structures in the health care system that are perpetuated when delivering care virtually. An equitable and sustainable approach to virtual care delivery will require applying an intersectionality lens on the strategies and solutions needed to address existing inequities in the system.

Purpose: The purpose of this study is to understand virtual care use (e.g. telephone and video visits) during the COVID-19 pandemic across three hospital-based ambulatory clinics (i.e. mental health, renal and respiratory care) and to describe associated patient and provider experiences. Design/methodology/approach: A mixed-methods convergent study was conducted including quantitative electronic medical records data on virtual care use, electronic surveys assessing domains of experience (e.g. satisfaction, acceptance and technology use) among patient and providers and semi-structured interviews exploring the associated barriers and facilitators of virtual care adoption. Findings: Virtual care adoption rates and relative modality use (telephone vs video) varied across specialty clinics. Mental health clinics) showed the greatest use of virtual care and greater use of video over telephone, as compared to renal and respiratory care, where telephone was used almost exclusively. Patients and providers reported an overall good satisfaction and acceptance of virtual care (60–72%) across clinics, but commonly observed barriers (technical problems, behavioral adaptations needed and inequity) persisted. Good value propositions, tech support and the presence of early adopters who can support others in workflow re-design and highlight value propositions of virtual care were listed as adoption facilitators. Originality/value: The study provides a unique opportunity to compare the rate of virtual care adoption before and during the COVID-19 pandemic across distinct specialties that operate within the same organizational and political setting. This study showed that the nature of the condition (e.g. mental health conditions) and the characteristics of the users (e.g. younger patients) may drive models of care with higher rate of video use. Focusing on removing common barriers, like providing tech support and ensuring equitable access to patients, continues to be important even in the context of high virtual care adoption rates during the pandemic.

- Abstract
Objective: We sought to understand and synthesize review-level evidence on the challenges associated with accessibility of virtual care among underserved population groups and to identify strategies that can improve access to, uptake of, and engagement with virtual care for these populations.Materials and Methods: A scoping review of reviews was conducted (protocol available at doi: 10.2196/22847). A total of 14 028 records were retrieved from MEDLINE, EMBASE, CINAHL, Scopus, and Epistemonikos databases. Data were abstracted, and challenges and strategies were identified and summarized for each underserved population group and across population groups.Results: A total of 37 reviews were included. Commonly occurring challenges and strategies were grouped into 6 key thematic areas based on similarities across communities: (1) the person's orientation toward health-related needs, (2) the person's orientation toward health-related technology, (3) the person's digital literacy, (4) technology design, (5) health system structure and organization, and (6) social and structural determinants of access to technology-enabled care. We suggest 4 important directions for policy development: (1) investment in digital health literacy education and training, (2) inclusive digital health technology design, (3) incentivizing inclusive digital health care, and (4) investment in affordable and accessible infrastructure.Discussion and Conclusion: Challenges associated with accessibility of virtual care among underserved population groups can occur at the individual, technological, health system, and social/structural determinant levels. Although the policy approaches suggested by our review are likely to be difficult to achieve in a given policy context, they are essential to a more equitable future for virtual care.

Purpose: It is currently unclear how the shift towards virtual care during the 2019 novel coronavirus (COVID-19) pandemic may have impacted chronic disease management at a population level. The goals of our study were to provide a description of the levels of use of virtual care services relative to in-person care in patients with chronic disease across Ontario, Canada and to describe levels of healthcare utilization in low versus high virtual care users. Methods: We used linked health administrative data to conduct a population-based, repeated cross-sectional study of all ambulatory patient visits in Ontario, Canada (January 1, 2018 to January 16, 2021). Further stratifications were also completed to examine patients with COPD, heart failure, asthma, hypertension, diabetes, mental illness, and angina. Patients were classified as low (max 1 virtual care visit) vs. high virtual care users. A time-series analysis was done using interventional autoregressive integrated moving average (ARIMA) modelling on weekly hospitalizations, outpatient visits, and diagnostic tests. Results: The use of virtual care increased across all chronic disease patient populations. Virtual care constituted at least half of the total care in all conditions. Both low and high virtual care user groups experienced a statistically significant reduction in hospitalizations and laboratory testing at the start of the pandemic. Hospitalization volumes increased again only among the high users, while testing increased in both groups. Outpatient visits among high users remained unaffected by the pandemic but dropped in low users. Conclusion: The decrease of in-person care during the pandemic was accompanied by an increase in virtual care, which ultimately allowed patients with chronic disease to return to the same visit rate as they had before the onset of the pandemic. Virtual care was adopted across various chronic conditions, but the relative adoption of virtual care varied by condition with highest rates seen in mental health. [ABSTRACT FROM AUTHOR]

Denitrification is a potential strategy for nitrate removal from wastewater. This study reports the isolation of a novel bacterium Georgenia daeguensis ARB2 which has not been earlier reported for treatment of wastewater. ARB2 was isolated from pharmaceutical wastewater and optimized for growth and nitrate removal under conditions of 10 mM nitrate stress (140 mgL
−1 NO 3 - - N ). It can utilize nitrate as a sole source of nitrogen, exhibits highest growth and aerobic denitrification using glycogen + maltose as a carbon source at pH 7.0, carbon-to-nitrogen ratio of 34, temperature 30 °C, and shaking speed of 100 rpm. ARB2 removes 20% of the initial nitrate concentration of 10 mM in 56 h, and 40% of the initial nitrate concentration of 1 mM in 52 h. Further, the efficacy of strain ARB2 was tested on real contaminated waters and was found to successfully reduce nitrate levels in them. The findings suggest that Georgenia daeguensis ARB2 has a potential application for the alleviation of nitrate under aerobic conditions. [ABSTRACT FROM AUTHOR]- Published

Background: The COVID-19 pandemic led to a dramatic shift in the delivery of outpatient medicine with reduced in-person visits and a transition to predominantly virtual visits. We sought to understand trends in visit patterns for ambulatory care sensitive conditions (ACSCs) commonly seen in internal medicine clinics.Methods: We included adult outpatients seen for an ACSC between March 15th, 2017 and March 14th, 2021 at a single-centre in Ontario, Canada. Monthly visits were assessed by visit type (new consultation, follow-up), diagnosis, and clinic. Time series analyses compared visit volumes pre- and post-pandemic. Proportion of virtual visits were compared before and during the pandemic. Patient and visit factors were compared between in-person and virtual visits.Results: 8274 patients with 34,021 visits were included. Monthly visits increased by 15% during the pandemic (p < 0.0001). New consultations decreased by 10% (p = 0.0053) but follow-up visits increased by 21% (p < 0.0001). Monthly heart failure visits increased by 43% (p < 0.0001) whereas atrial fibrillation visits decreased. Pre- pandemic, < 1% of visits were virtual compared to 82% during the pandemic (p < 0.0001). Less than half of heart failure visits were virtual whereas > 95% of diabetes visits were virtual.Conclusions: We found a significant increase in overall visits to internal medicine clinics driven by increased volumes of follow-up visits, which more than offset decreased new consultations. There was variability in visit trends and uptake of virtual care by visit diagnosis, which may indicate challenges with delivery of virtual care for certain conditions.

Background Telemedicine adoption has grown significantly due to the coronavirus of 2019 pandemic; however, it remains unclear what the impact of widespread telemedicine use is on healthcare utilization among individuals with psychosis. Objectives To investigate the impact of telemedicine use on changes in healthcare utilization among patients with chronic psychotic disorders (CPDs). Study Design We conducted a population-based, retrospective propensity-matched cohort study using healthcare administrative data in Ontario, Canada. Patients were included if they had at least one ambulatory visit between March 14, 2020 and September 30, 2020 and a CPD diagnosis any time before March 14, 2020. Telemedicine users (2+ virtual visits after March 14, 2020) were propensity score-matched 1:1 with standard care users (minimum of 1 in-person or virtual ambulatory visit and maximum of 1 virtual visit after March 14, 2020) based on several baseline characteristics. Monthly use of various healthcare services was compared between the two groups from 12 months before to 3 months after their index in-person or virtual ambulatory visit after March 14, 2020 using generalized estimating equations (eg, hospitalizations, emergency department [ED] visits, and outpatient physician visits). The slope of change over the study period (ie, rate ratio) as well as a ratio of slopes, were calculated for both telemedicine and standard care groups for each outcome. Study Results A total of 18 333 pairs of telemedicine and standard care patients were identified after matching (60.8% male, mean [SD] age 45.4 [16.3] years). There was a significantly greater decline across time in the telemedicine group compared to the standard care group for ED visits due to any psychiatric conditions (ratio of slopes for telemedicine vs standard care (95% CI), 0.98 (0.98 to 0.99)). However, declines in primary care visit rates (ratio of slopes for telemedicine vs standard care (1.01 (1.01 to 1.02)), mental health outpatient visits with primary care (1.03 (1.03 to 1.04)), and all-cause outpatient visits with primary care (1.01 (1.01 to 1.02)), were steeper among the standard care group than telemedicine group. Conclusions Overall, patients with CPDs appeared to benefit from telemedicine as evidenced by increased outpatient healthcare utilization and reductions in ED visits due to psychiatric conditions. This suggests that telemedicine may have allowed this patient group to have better access and continuity of care during the initial waves of the pandemic. [ABSTRACT FROM AUTHOR]

Although a majority of tumors in the Cerebellopontine Angle (CPA) are vestibular schwannomas (VS), other masses can also be seen in the region and differentiation of various CPA tumors, particularly meningiomas can be difficult on imaging alone. Treatment options may vary based on specific pathology of the CPA tumor. In this study, the presence of microhemorrhage (MH) and other imaging features such as size of lesion, cystic features and pattern of IAC extension, were evaluated as a tool in distinguishing VS from other CPA masses. A review of CPA masses in the last 11 years at our institution was performed. All the pathology proven tumors with at least 1 pre-operative MRI were considered for analysis. A T2* GRE or SWI sequence was used to assess presence of MH within the lesion. Pattern of IAC extension ('centric' versus 'eccentric') of tumor was also evaluated. A total of 147 patients were reviewed out of which 102 patients (with T2* GRE or SWI) were included for analysis of MH. 57 patients (56%) had VS as the final histopathological diagnosis and 45 patients (44%) had other types of tumor. A sensitivity of 82% and a specificity of 98% was noted for the presence of MH favoring the diagnosis of VS from other tumors (p < 0.001). All meningiomas with IAC extension (25/31) showed an 'eccentric' pattern of extension into the canal. Visualization of MH and pattern of IAC extension is useful in the differentiation of schwannomas from other CPA masses, particularly meningiomas. [ABSTRACT FROM AUTHOR]

QUANTUM computing ,DATA encryption ,INTEGERS ,FACTORIZATION ,CONSTRAINT satisfaction - Abstract
Encryption is the process of securing confidential data that bars a third party's access to the information.RSA encryption utilises the property of complexity classes wherein the problem of prime integer factorization lies inside the Non-Polynomial time (NP-Hard) class, which makes it impervious to classical computers. Since it is so hard to break even for a computer, it becomes important to do encryption for all the secure transactions. Although it lies outside the capabilities of traditional computing, the recent developments in the field of quantum computing can be utilised to break RSA Encryption. The approach involves mapping of qubits used in a quantum machine to a constraint satisfaction problem (CSP) and then using them to check for factors. This consists of the use of a Multiplicative Boolean circuit in which the qubits utilised by the machine replaces the variables. These Qubits are then mapped as per the gates involved, and the factorization problem is thus transformed into a CSP problem, through which, the factors can be easily found. Once known, these factors can be used to calculate the public and private keys effectively breaking the encryption security. We provide a novel approach to highlight the importance of developing Post-Quantum cryptography techniques for providing a secure channel of communication. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Virtual care for patients with coronavirus disease 2019 (COVID-19) allows providers to monitor COVID-19-positive patients with variable trajectories while reducing the risk of transmission to others and ensuring health care capacity in acute care facilities. The objective of this descriptive analysis was to assess the initial adoption, feasibility and safety of a family medicine–led remote monitoring program, COVIDCare@Home, to manage the care of patients with COVID-19 in the community. Methods: COVIDCare@Home is a multifaceted, interprofessional team–based remote monitoring program developed at an ambulatory academic centre, the Women's College Hospital in Toronto. A descriptive analysis of the first cohort of patients admitted from Apr. 8 to May 11, 2020, was conducted. Lessons from the implementation of the program are described, focusing on measure of adoption (number of visits per patient total, with a physician or with a nurse; length of follow-up), feasibility (received an oximeter or thermometer; consultation with general internal medicine, social work or mental health, pharmacy or acute ambulatory care unit) and safety (hospitalizations, mortality and emergency department visits). Results: The COVIDCare@Home program cared for a first cohort of 97 patients (median age 41 yr, 67% female) with 415 recorded virtual visits. Patients had a median time from positive testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to first appointment of 3 (interquartile range [IQR] 2–4) days, with a median virtual follow-up time of 8 (IQR 5–10) days. A total of 4 (4%) had an emergency department visit, with no patients requiring hospitalization and no deaths; 16 (16%) of patients required support with mental and social health needs. Interpretation: A family medicine–led, team-based remote monitoring program can safely manage the care of outpatients diagnosed with COVID-19. Virtual care approaches, particularly those that support patients with more complex health and social needs, may be an important part of ongoing health system efforts to manage subsequent waves of COVID-19 and other diseases.

While there has been a rapid growth of digital health apps to support chronic diseases, clear standards on how to best evaluate the quality of these evolving tools are absent. This scoping review aims to synthesize the emerging field of mobile health app quality assessment by reviewing criteria used by previous studies to assess the quality of mobile apps for chronic disease management. A literature review was conducted in September 2017 for published studies that use a set of quality criteria to directly evaluate two or more patient-facing apps supporting promote chronic disease management. This resulted in 8182 citations which were reviewed by research team members, resulting in 65 articles for inclusion. An inductive coding schema to synthesize the quality criteria utilized by included articles was developed, with 40 unique quality criteria identified. Of the 43 (66%) articles that reported resources used to support criteria selection, 19 (29%) used clinical guidelines, and 10 (15%) used behavior change theory. The most commonly used criteria included the presence of user engagement or behavior change functions (97%, n = 63) and technical features of the app such as customizability (20%, n = 13, while Usability was assessed by 24 studies (36.9%). This study highlights the significant variation in quality criteria employed for the assessment of mobile health apps. Future methods for app evaluation will benefit from approaches that leverage the best evidence regarding the clinical impact and behavior change mechanisms while more directly reflecting patient needs when evaluating the quality of apps.

- Abstract
Background: The coronavirus disease 2019 (COVID-19) pandemic is thought to have increased use of virtual care, but population-based studies are lacking. We aimed to assess the uptake of virtual care during the COVID-19 pandemic using comprehensive population-based data from Ontario. Methods: This was a repeated cross-sectional study design. We used administrative data to evaluate changes in in-person and virtual visits among all residents of Ontario before (2012–2019) and during (January–August 2020) the COVID-19 pandemic. We included all patients who had an ambulatory care visit in Ontario. We excluded claims for patients who were not Ontario residents or had an invalid or missing health card number. We compared monthly or quarterly virtual care use across age groups, neighbourhood income quintiles and chronic disease subgroups. We also examined physician characteristics that may have been associated with virtual care use. Results: Among all residents of Ontario (population 14.6 million), virtual care increased from 1.6% of total ambulatory visits in the second quarter of 2019 to 70.6% in the second quarter of 2020. The proportion of physicians who provided 1 or more virtual visits per year increased from 7.0% in the second quarter of 2019 to 85.9% in the second quarter of 2020. The proportion of Ontarians who had a virtual visit increased from 1.3% in 2019 to 29.2% in 2020. Older patients were the highest users of virtual care. The proportion of total virtual visits that were provided to patients residing in rural areas (v. urban areas) declined significantly between 2012 and 2020, reflecting a shift in virtual care to a service increasingly used in urban centres. The rates of virtual care use increased similarly across all conditions and across all income quintiles. Interpretation: Our findings show that Ontario's approach to virtual care led to broad adoption across all provider groups, patient age, types of chronic diseases and neighborhood income. These findings have policy implications, including use of virtual care billing codes, for the ongoing use of virtual care during the second wave of the pandemic and beyond. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives To evaluate the uptake of a platform for virtual visits in primary care, examine patient and physician preferences for virtual communication methods and report on characteristics of visits and patients experience of care. Design A retrospective cohort study. Setting Primary care practices within five regions in Ontario, Canada after 18 months of access to virtual care services. Participants 326 primary care providers and 14 291 registered patients. Interventions Providers used a platform that allowed them to connect with their patients through synchronous (audio/video) and/or asynchronous (secure messaging) communication. Main outcome measures User-level data from the platforms including patient demographics, practice characteristics, communication modality used, visit characteristics and patients’ satisfaction. Results Among the participants, 44% of registered patients and 60% of registered providers used the platform at least once. Among patient users, 51% completed at least one virtual visit. The majority of virtual visits (94%) involved secure messaging. The most common patient requests were for medication prescriptions (24%) and follow-up from previous appointment (22%). The most common provider request was to follow-up on test results (59%). Providers indicated that 81% of virtual visits required no follow-up for that issue and 99% of patients reported that they would use virtual care services again. Conclusions While there are a growing number of primary care video visit services, our study found that both patients and providers in rostered practices prefer secure messaging over video. Despite fears that virtual visits would be overused by patients, when patients connected with their own primary care provider, many virtual visits appeared to replace in-person visits, and patients did not overwhelm physicians with requests. This approach may improve access and continuity in primary care. [ABSTRACT FROM AUTHOR]

Background: Although antibiotics have little or no benefit for most upper respiratory tract infections (URTIs), they continue to be prescribed frequently in primary care. Physicians perceive that patients' expectations influence their antibiotic prescribing practice; however, not all patients seek antibiotic treatment despite having similar symptoms. In this study, we explored patients' views about URTIs, and the ways patients manage them (including attendance in primary care and taking antibiotics). Methods: Using a qualitative descriptive design, adult English-speaking individuals at a Canadian health center were recruited through convenient sampling. The participants were interviewed using semi-structured interview guide based on the Common Sense-Self-Regulation Model (CS-SRM). The interviews were transcribed verbatim and coded according to CS-SRM dimensions (illness representations, coping strategies). Sampling continued until thematic saturation was achieved. Thematic analysis related to the dimensions of CS-SRM was applied. Results: Generally, participants had accurate perception about the symptoms of URTIs, as well as how to prevent and manage them. However, some participants revealed misconceptions about the causes of URTIs. Almost all participants mentioned that they only visited their doctor if their symptoms got progressively worse and they could no longer self-manage the symptoms. When visiting a doctor, most participants reported that they did not seek antibiotics. They expected to receive an examination and an explanation for their symptoms. Conclusion: Our participants reported good understanding regarding the likely lack of benefit from antibiotics for URTIs. Developing interventions that specifically help patients discuss their concerns with their physicians, instead of providing more education to public may help in reducing the use of unnecessary antibiotics.

Background: Heart failure patients often present with frailty and/or multi-morbidity, complicating care and service delivery. The Chronic Care Model (CCM) is a useful framework for designing care for complex patients. It assumes responsibility of several actors, including frontline providers and health-care administrators, in creating conditions for optimal chronic care management. This qualitative case study examines perceptions of care among providers and administrators in a large, urban health system in Canada, and how the CCM might inform redesign of care to improve health system functioning. Methods: Sixteen semi-structured interviews were conducted between August 2014 and January 2016. Interpretive analysis was conducted to identify how informants perceive care among this population and the extent to which the design of heart failure care aligns with elements of the CCM. Results: Current care approaches could better align with CCM elements. Key changes to improve health system functioning for complex heart failure patients that align with the CCM include closing knowledge gaps, standardizing treatment, improving interdisciplinary communication and improving patient care pathways following hospital discharge. Conclusions: The CCM can be used to guide health system design and interventions for frail and multi-morbid heart failure patients. Addressing care- and service-delivery barriers has important clinical, administrative and economic implications. [ABSTRACT FROM AUTHOR]

Background: Antibiotics are prescribed frequently for upper respiratory tract infections (URTIs) even though most URTIs do not require antibiotics. This over-prescription contributes to antibiotic resistance which is a major health problem globally. As physicians' prescribing behaviour is influenced by patients' expectations, there may be some opportunities to reduce antibiotic prescribing using patient-oriented interventions. We aimed to identify these interventions and to understand which ones are more effective in reducing unnecessary use of antibiotics for URTIs. Methods: We conducted a systematic review by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (OVID), EMBASE (OVID), CINAHL, and the Web of Science. We included English language randomized controlled trials (RCTs), quasi-RCTs, controlled before and after studies, and interrupted time series (ITS) studies. Two authors screened the abstract/titles and full texts, extracted data, and assessed study risk of bias. Where pooling was appropriate, a meta-analysis was performed by using a random-effects model. Where pooling of the data was not possible, a narrative synthesis of results was conducted. Results: We included 13 studies (one ITS, one cluster RCTs, and eleven RCTs). All interventions could be classified into two major categories: delayed prescriptions (seven studies) and patient/public information and education interventions (six studies). Our meta-analysis of delayed prescription studies observed significant reductions in the use of antibiotics for URTIs (OR = 0.09, CI 0.03 to 0.23; six studies). A subgroup analysis showed that prescriptions that were given at a later time and prescriptions that were given at the index consultation had similar effects. The studies in the patient/public information and education group varied according to their methods of delivery. Since only one or two studies were included for each method, we could not make a definite conclusion on their effectiveness. In general, booklets or pamphlets demonstrated promising effects on antibiotic prescription, if discussed by a practitioner. Conclusions: Patient-oriented interventions (especially delayed prescriptions) may be effective in reducing antibiotic prescription for URTIs. Further research is needed to investigate the costs and feasibility of implementing these interventions as part of routine clinical practice. Systematic review registration: PROSPERO CRD42016048007.

Choosing Wisely (CW) campaigns globally have focused attention on the need to reduce low-value care, which can represent up to 30% of the costs of healthcare. Despite early enthusiasm for the CW initiative, few large-scale changes in rates of low-value care have been reported since the launch of these campaigns. Recent commentaries suggest that the focus of the campaign should be on implementation of evidencebased strategies to effectively reduce low-value care. This paper describes the Choosing Wisely De-Implementation Framework (CWDIF), a novel framework that builds on previous work in the field of implementation science and proposes a comprehensive approach to systematically reduce low-value care in both hospital and community settings and advance the science of de-implementation. The CWDIF consists of five phases: Phase 0, identification of potential areas of low-value healthcare; Phase 1, identification of local priorities for implementation of CW recommendations; Phase 2, identification of barriers to implementing CW recommendations and potential interventions to overcome these; Phase 3, rigorous evaluations of CW implementation programmes; Phase 4, spread of effective CW implementation programmes. We provide a worked example of applying the CWDIF to develop and evaluate an implementation programme to reduce unnecessary preoperative testing in healthy patients undergoing low-risk surgeries and to further develop the evidence base to reduce low-value care.

Summary: With the increase in industrial and agricultural activities, a large amount of nitrogenous compounds are released into the environment, leading to nitrate pollution. The perilous effects of nitrate present in the environment pose a major threat to human and animal health. Bioremediation provides a cost‐effective and environmental friendly method to deal with this problem. The process of aerobic denitrification can reduce nitrate compounds to harmless dinitrogen gas. This review provides a brief view of the exhaustive role played by aerobic denitrifiers for tackling nitrate pollution under different ecological niches and their dependency on various environmental parameters. It also provides an understanding of the enzymes involved in aerobic denitrification. The role of aerobic denitrification to solve the issues faced by the conventional method (aerobic nitrification–anaerobic denitrification) in treating nitrogen‐polluted wastewaters is elaborated.

An innovative single-phase and three-phase H-bridge derived multilevel inverter topology is being proposed in this manuscript. The proposed topology makes use of relatively fewer switching devices compared to conventional Cascaded HBridge (CHB) multilevel inverter. In other words, the proposed inverter topology is capable of producing more number of levels in the voltage waveform with same number of switching devices. It is also established in this paper, that this proposed topology is superior in terms of requirement of lesser number of gate driving circuits and reduction in the harmonic content in the output voltage waveform. The proposed inverter topologies are driven by SPWM modulation technique. These converter topologies are not only beneficial for the power conditioning systems in the power system network but also for the other novel applications like in marine ships. In this manuscript, the performance comparisons of the proposed inverter topologies with that of conventional topology based on simulation results with MATLAB/SIMULINK have been presented.

Introduction: Integrated care is a goal of many health care systems. However, operationalizing and implementing integrated care remains challenging especially in continuously evolving policy environments. We report on a policy symposium held in 2017 focused on operationalizing a particular integrated care policy in the context of policy evolution in Ontario, Canada. Methodology: Forty-five participants attended the symposium including government employees, health care leaders, researchers, clinicians, and patient representatives. The symposium included presentations from representatives of each group and breakout sessions. Two trained observers recorded observational field notes. Results: We report four recommendations and fourteen sub-recommendations which arose regarding the implementation of the policy. We highlight four important tensions which characterize challenges regarding its implementation, and discuss the recommendations in the context of Collaborative Governance. Discussion: We outline how the recommendations could be strengthened by collaborative governance and identify where this framework could support governance and leadership challenges associated with implementing integrated care. We describe the unique challenges posed by working towards these goals in an evolving policy environment. Conclusion: We draw on collaborative governance to generate insights for leaders implementing integrated care and conclude by addressing the importance of maintaining collaborative governance initiatives under circumstances of unstable policy environments.

META-analysis ,WEB search engines - Abstract
Importance: Studies of interventions to reduce low-value care are increasingly common. However, little is known about how the effects of such interventions are measured.Objective: To characterize measures used to assess interventions to reduce low-value care.Evidence Review: We searched PubMed and Web of Science to identify studies published between 2010 and 2016 that examined the effects of interventions to reduce low-value care. We also searched ClinicalTrials.gov to identify ongoing studies. We extracted data on characteristics of studies, interventions, and measures. We then developed a framework to classify measures into the following categories: utilization (e.g., number of tests ordered), outcome (e.g., mortality), appropriateness (e.g., overuse of antibiotics), patient-reported (e.g., satisfaction), provider-reported (e.g., satisfaction), patient-provider interaction (e.g., informed decision-making elements), value, and cost. We also determined whether each measure was designed to assess unintended consequences.Findings: A total of 1805 studies were identified, of which 101 published and 16 ongoing studies were included. Of published studies (N = 101), 68% included at least one measure of utilization, 41% of an outcome, 52% of appropriateness, 36% of cost, 8% patient-reported, and 3% provider-reported. Funded studies were more likely to use patient-reported measures (17% vs 0%). Of ongoing studies (registered trials) (N = 16), 69% included at least one measure of utilization, 75% of an outcome, 50% of appropriateness, 19% of cost, 50% patient-reported, 13% provider-reported, and 6% patient-provider interaction. Of published studies, 34% included at least one measure of an unintended consequence as compared to 63% of ongoing studies.Conclusions and Relevance: Most published studies focused on reductions in utilization rather than on clinically meaningful measures (e.g., improvements in appropriateness, patient-reported outcomes) or unintended consequences. Investigators should systematically incorporate more clinically meaningful measures into their study designs, and sponsors should develop standardized guidance for the evaluation of interventions to reduce low-value care.

- Abstract
Objective To evaluate the utility of a novel discharge tool adapted for heart failure (HF) on patient experience. Design Semistructured interviews assessed the utility of a novel discharge tool adapted for HF; patient-oriented discharge summary (PODS-HF) at 72 hours and 30 days after leaving hospital. Interviews were recorded and transcribed verbatim. Three investigators used directed content analysis to determine themes and subthemes from the narrative data. Setting The cardiology ward of an urban academic institution in Canada. Participants 13 patients and caregivers completed 24 interviews. Eligible patients were >18 years and admitted with a diagnosis of HF. Results Analysis revealed six interconnected themes: (1) Utility of discharge instructions: how patients perceive and use written and verbal instructions. Patients receiving PODS-HF identified value in the patientcentred summarised content. (2) Adherence: strategies used by patients to enhance adherence to medications, diet and lifestyle changes. PODS-HF provides a strong visual reminder, particularly early postdischarge. (3) Adaptation: how patients incorporate changes into 'new norms'. This was more evident by 30 days, and those using PODS-HF had less unscheduled visits and readmissions. (4) Relationships with healthcare providers: patients' perceptions of the roles of family physicians and specialists in follow-up care. (5) Role of family and caregivers: the pivotal role of caregivers in supporting adherence and adaptation. (6) Follow-up phone calls: the utility of follow-up calls, particularly early after discharge as a means of providing clarification, reassurance and education. Conclusion PODS-HF is a useful tool that increases patients' confidence to self-manage and facilitates adherence by providing relevant written information to reference after discharge.

PRIMARY care ,LUMBAR pain ,LUMBAR vertebrae ,SYMPTOMS ,DIAGNOSTIC imaging ,FAMILY medicine - Abstract
Background: At any one time, one in every five Canadians has low back pain (LBP), and LBP is one of the most common health problems in primary care. Guidelines recommend that imaging not be routinely performed in patients presenting with LBP without signs or symptoms indicating a potential pathological cause. Yet imaging rates remain high for many patients who present without such indications. Inappropriate imaging can lead to inappropriate treatments, results in worse health outcomes and causes harm from unnecessary radiation. There is a need to understand the extent of, and factors contributing to, inappropriate imaging for LBP, and to develop effective strategies that target modifiable barriers and facilitators. The primary study objectives are to determine: 1) The rate of, and factors associated with, inappropriate lumbar spine imaging (x-ray, CT scan and MRI) for people with non-specific LBP presenting to primary care clinicians in Ontario; 2) The barriers and facilitators to reduce inappropriate imaging for LBP in primary care settings.Methods: The project will comprise an inception cohort study and a concurrent qualitative study. For the cohort study, we will recruit 175 primary care clinicians (50 each from physiotherapy and chiropractic; 75 from family medicine), and 3750 patients with a new episode of LBP who present to these clinicians. Clinicians will collect data in the clinic, and each participant will be tracked for 12 months using Ontario health administrative and self-reported data to measure diagnostic imaging use and other health outcomes. We will assess characteristics of the clinicians, patients and encounters to identify variables associated with inappropriate imaging. In the qualitative study we will conduct in-depth interviews with primary care clinicians and patients.Discussion: This will be the first Canadian study to accurately document the extent of the overuse of imaging for LBP, and the first worldwide to include data from the main healthcare professions offering primary care for people with LBP. This study will provide robust information about rates of inappropriate imaging for LBP, along with factors associated with, and an understanding of, potential reasons for inappropriate imaging.

Background: Web-based mental health applications may be beneficial, but adoption is often low leaving optimal implementation and payment models unclear. This study examined which users were interested in extended access to a web-based application beyond an initial 3-month trial period and evaluated if an additional 3 months of access was beneficial. Methods: This study was a concealed extension of a multi-center, pragmatic randomized controlled trial that assessed the benefit of 3 months of access to the Big White Wall (BWW), an anonymous web-based moderated, multi-component mental health application offering self-directed activities and peer support. Trial participants were 16 years of age or older, recruited from hospital-affiliated mental health programs. Participants who received access to the intervention in the main trial and completed 3-month outcome assessments were offered participation. We compared those who were and were not interested in an extension of the intervention, and re-randomized consenting participants 1:1 to receive extended access or not over the subsequent 3 months. Use of the intervention was monitored in the extension group and outcomes were measured at 3 months after re-randomization in both groups. The primary outcome was mental health recovery as assessed by total score on the Recovery Assessment Scale (RAS-r), as in the main trial. Linear mixed models were used to examine the time by group interaction to assess for differences in responses over the 3-month extension study. Results: Of 233 main trial participants who responded, 119 (51.1%) indicated an interest in receiving extended BWW access. Those who were interested had significantly higher baseline anxiety symptoms compared to those who were not interested. Of the 119, 112 were re-randomized (55 to extended access, 57 to discontinuation). Only 21 of the 55 extended access participants (38.2%) used the intervention during the extension period. Change in RAS-r scores over time was not significantly different between groups (time by group, F(1,77) = 1.02; P =.31). Conclusions: Only half of eligible participants were interested in extended access to the intervention with decreasing use over time, and no evidence of added benefit. These findings have implications for implementation and payment models for this type of web-based mental health intervention. Trial registration: Clinicaltrials.govNCT02896894.

- Abstract
Background: Although there is a growing body of literature on the outcomes and impacts of remote home management with peritoneal dialysis (PD) patients, less is understood how this virtual care solution impacts the quality and efficiency of the healthcare system care. In this context, a study was undertaken to understand the perceptions of patients and their caregivers, healthcare providers, health system decision makers, and vendors associated with a remote monitoring and tracking solution aimed at enhancing the outcomes and experiences of chronic kidney disease (CKD) patients receiving PD at home. Methods: A qualitative design using semi-structured interviews with 25 stakeholders was used in this study. Narrative data were analyzed by a thematic analysis approach. Results: The following two themes emerged from the data: (1) leveraging data to monitor and intervene to keep patients safe and (2) increasing efficiencies and having control over supplies. Discussion: Our study findings elucidated the ability of patients (and in some cases, caregivers) to monitor and trend their data and order and track directly on-line their dialysis supplies were key to their active participation in managing their CKD and keeping them safe at home. Their active participation and functionality of the virtual care solution also led to enhanced efficiencies (eg, process faster, easier, convenient, time savings) for both patients and healthcare providers. Conclusion: The virtual care solution showed promising signs of a patient-centric approach and may serve as a blueprint for other virtual care solutions for chronic disease management.

Background The development of new virtual care technologies (including telehealth and telemedicine) is growing rapidly, leading to a number of challenges related to health policy and planning for health systems around the world. Methods We brought together a diverse group of health system stakeholders, including patient representatives, to engage in policy dialogue to set health system priorities for the application of virtual care in the primary care sector in the Province of Ontario, Canada. We applied a nominal group technique (NGT) process to determine key priorities, and synthesized these priorities with group discussion to develop recommendations for virtual care policy. Methods included a structured priority ranking process, open-ended note-taking, and thematic analysis to identify priorities. Results Recommendations were summarized under the following themes: (a) identify clear health system leadership to embed virtual care strategies into all aspects of primary and community care; (b) make patients the focal point of health system decision-making; (c) leverage incentives to achieve meaningful health system improvements; and (d) building virtual care into streamlined workflows. Two key implications of our policy dialogue are especially relevant for an international audience. First, shifting the dialogue away from technology toward more meaningful patient engagement will enable policy planning for applications of technology that better meet patients' needs. Second, a strong conceptual framework on guiding the meaningful use of technology in health care settings is essential for intelligent planning of virtual care policy. Conclusions Policy planning for virtual care needs to shift toward a stronger focus on patient engagement to understand patients' needs. [ABSTRACT FROM AUTHOR]

Many virtual care initiatives focus heavily on video visits, essentially mimicking face-to-face visits. Meanwhile, clinicians in established settings continue to use the oldest modality, phone calls, and some use the most ubiquitous, asynchronous messaging. The latter, along with live chat and chatbots, could be transformative if workflows were redesigned to incorporate it. With multiple modalities now available for use in virtual care, the central problem is to direct patient-provider interactions to the channels generating the most value. Marketers call this channel management and use sophisticated approaches to implement it. We propose an adaptation of channel management to virtual care and discuss anticipated challenges to its implementation. [ABSTRACT FROM AUTHOR]

Objective: To quantitatively test the hypothesis that older patients have increased thyroarytenoid muscle atrophy by comparing thyroarytenoid muscle volumes across different age groups. Methods: A retrospective chart review was conducted. The study included 111 patients with no history of laryngeal pathology. Two investigators reviewed magnetic resonance imaging studies of these patients and manually traced the thyroarytenoid muscles on multiple slices bilaterally. Thyroarytenoid muscle volumes were then computed using imaging analysis software. Patients were stratified into three age groups (18–50 years, 51–64 years, and 65 years or older) for comparison. Results: Intra- and inter-rater reliabilities were excellent for all measurements (intraclass correlation co-efficient > 0.90). There was no statistically significant difference in the mean volumes of left and right thyroarytenoid muscles in all age and gender groups. Conclusion: Given the lack of statistically significant difference in thyroarytenoid muscle volume between age groups on magnetic resonance imaging, the prevailing assumption that age-related thyroarytenoid muscle atrophy contributes to presbyphonia should be re-examined.
