Variability in opioid prescribing practices among cardiac surgeons and trainees.

BACKGROUND AND AIM: The opioid epidemic has become a major public health crisis in recent years. Discharge opioid prescription following cardiac surgery has been associated with opioid use disorder; however, ideal practices remain unclear. Our aim was to examine current practices in discharge opioid prescription among cardiac surgeons and trainees. METHODS: A survey instrument with open- and closed-ended questions, developed through a 3-round Delphi method, was circulated to cardiac surgeons and trainees via the Canadian Society of Cardiac Surgeons. Survey questions focused on routine prescription practices including type, dosage and duration. Respondents were also asked about their perceptions of current education and guidelines surrounding opioid medication. RESULTS: Eighty-one percent of respondents reported prescribing opioids at discharge following routine sternotomy-based procedures, however, there remained significant variability in the type and dose of medication prescribed. The median (interquartile range) number of pills prescribed was 30 (20-30) with a median total dose of 135 (113-200) Morphine Milligram Equivalents. Informal teaching was the most commonly reported primary influence on prescribing habits and a lack of formal education regarding opioid prescription was associated with a higher number of pills prescribed. A majority of respondents (91%) felt that there would be value in establishing practice guidelines for opioid prescription following cardiac surgery. CONCLUSIONS: Significant variability exists with respect to routine opioid prescription at discharge following cardiac surgery. Education has come predominantly from informal sources and there is a desire for guidelines. Standardization in this area may have a role in combatting the opioid epidemic.

Expression of the Frizzled receptors and their co-receptors in calcified human aortic valves.

The cellular mechanisms that induce calcific aortic stenosis are yet to be unraveled. Wnt signaling is increasingly being considered as a major player in the disease process. However, the presence of Wnt Frizzled (Fzd) receptors and co-receptors LRP5 and 6 in normal and diseased human aortic valves remains to be elucidated. Immunohistochemistry and quantitative polymerase chain reaction were used to determine Fzd receptor expression in normal and calcified human aortic valve tissue, as well as human aortic valve interstitial cells (HAVICs) isolated from calcified and normal human aortic valves. There was significantly higher mRNA expression of 4 out of the 10 Fzd receptors in calcified aortic valve tissues and 8 out of the 10 in HAVICs, and both LRP5/6 co-receptors in calcified aortic valves (P < 0.05). These results were confirmed by immunohistochemistry, which revealed abundant increase in immunoreactivity for Fzd3, 7, and 8, mainly in areas of lipid core and calcified nodules of diseased aortic valves. The findings of abundant expression of Fzd and LRP5/6 receptors in diseased aortic valves suggests a potential role for both canonical and noncanonical Wnt signaling in the pathogenesis of human aortic valve calcification. Future investigations aimed at targeting these molecules may provide potential therapies for aortic valve stenosis.

Virtual Care With Digital Technologies for Rural Canadians Living With Cardiovascular Disease.

Canada is a wealthy nation with a geographically diverse population, seeking health innovations to better serve patients in accordance with the Canada Health Act. In this country, population and geography converge with social determinants, policy, procurement regulations, and technological advances with the goal to achieve equity in the management and distribution of health care. Rural and remote patients are a vulnerable population; when managing chronic conditions like cardiovascular disease, there is currently inequity to accessing specialist physicians at the recommended frequency-increasing the likelihood of poor health outcomes. Ensuring equitable care for this population is an unrealized priority of several provincial and federal government mandates. Virtual care technology might provide practical, economical, and innovative solutions to remedy this discrepancy. We conducted a scoping review of the literature pertaining to the use of virtual care technologies to monitor patients living in rural areas of Canada with cardiovascular disease. A search strategy was developed to identify the literature specific to this context across 3 bibliographic databases. Two hundred thirty-two unique citations were ultimately assessed for eligibility, of which 37 met the inclusion criteria. In our assessment of these articles, we provide a summary of the interventions studied, their reported effectiveness in reducing adverse events and mortality, the challenges to implementation, and the receptivity of these technologies among patients, providers, and policy-makers. Furthermore, we glean insight into the barriers and opportunities to ensure equitable care for rural patients and conclude that there is an ongoing need for clinical trials on virtual care technologies in this context.

Le Canada, pays riche dont la population est répartie dans des régions géographiquement diversifiées, reste à l'affût des innovations en matière de santé pour mieux servir les patients conformément à la Loi canadienne sur la santé. Dans ce pays, la population et la géographie ainsi que les déterminants sociaux, les politiques, la réglementation des marchés publics et les progrès technologiques convergent vers un objectif d'équité dans la gestion et la distribution des soins de santé. Les patients des régions rurales et éloignées constituent une population vulnérable; la prise en charge de maladies chroniques comme les maladies cardiovasculaires est marquée par des inégalités en ce qui concerne l'accès aux médecins spécialistes à la fréquence recommandée ­ ce qui augmente le risque de problèmes de santé. La garantie d'un accès équitable aux soins de santé pour cette population constitue une priorité non concrétisée pour plusieurs gouvernements provinciaux et fédéraux. Les technologies des soins virtuels pourraient offrir des solutions pratiques, économiques et novatrices afin de remédier à la disparité qui persiste. Nous avons effectué une revue exploratoire de la littérature relative à l'utilisation des technologies des soins virtuels pour le suivi des patients atteints de maladies cardiovasculaires vivant dans les régions rurales du Canada. Une stratégie de recherche a été élaborée pour recenser les articles visant spécifiquement ce contexte dans trois bases de données bibliographiques. Au terme de la recherche, 232 références uniques ont été évaluées en fonction des critères d'admissibilité; 37 y répondaient. Dans notre évaluation des articles, nous résumons les interventions étudiées, leur efficacité rapportée quant à la réduction des événements indésirables et de la mortalité, les difficultés de mise en œuvre et la réceptivité des patients, des fournisseurs de soins et des décideurs politiques aux technologies utilisées. En outre, nous offrons un aperçu des obstacles à surmonter et des occasions à saisir pour garantir un accès équitable aux soins de santé dans les régions rurales et nous concluons que des études cliniques sur les technologies des soins virtuels demeurent nécessaires dans ce contexte.
