    Abstract Background Cardiovascular disease (CVD) is a major cause of morbidity and mortality in Canada. Assessment and management of CVD risk is essential in reducing disease burden. This includes both clinical risk factors and socioeconomic factors, though few studies report on socioeconomic status in relation to CVD risk and treatment. The primary objective of this study was to estimate the cardiovascular risk of patients attending primary care practices across Canada; secondly, to evaluate concordance with care indicators suggested by current clinical practice guidelines for statin prescribing according to patients’ cardiovascular risk and socioeconomic status. Methods This cross-sectional observational study used the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) database, which is comprised of clinical data from primary care electronic medical records. Patients aged 35-75y with at least one visit to their primary care provider between 2012 and 2016 were included. Patients were assigned to a CVD risk category (high, medium, low) and a deprivation quintile was calculated for those with full postal code available. Descriptive analyses were used to determine the proportion of patients in each risk category. Logistic regression was used to evaluate the consistency of statin prescribing according to national clinical guidelines by risk category and deprivation quintile. Results A total of 324,526 patients were included. Of those, 116,947 (36%) of patients were assigned to a high CVD risk category, primarily older adults, males, and those with co-morbidities. There were statistically significant differences between least (quintile 1) and most (quintile 5) deprived socioeconomic quintiles, with those at high CVD risk disproportionately in Q5 (odds ratio 1.4). Overall, 48% of high-risk patients had at least one statin prescription in their record. Patients in the lower socioeconomic groups had a higher risk of statin treatment which deviated from clinical guidelines. Conclusions Primary care patients who are at high CVD risk are more often male, older, have more co-morbidities and be assigned to more deprived SES quintiles, compared to those at low CVD risk. Additionally, patients who experience more challenging socioeconomic situations may be less likely to receive CVD treatment that is consistent with care guidelines.

    Description of Continuous Palliative Sedation Practices in a Large Health Region and Comparison with Clinical Practice Guidelines

    Background: Published reports of continuous palliative sedation therapy (CPST) suggest heterogeneity in practice. There is a paucity of reports that compare practice with clinical guidelines. Objectives: To assess adherence of continuous palliative sedation practices with criteria set forth in local clinical guidelines, and to describe other features including prevalence, medication dosing, duration, multidisciplinary team involvement, and concurrent therapies. Design: Retrospective chart review. Settings/Subjects: We included cases in which a midazolam infusion was ordered at the end of life. Study sites included four adult hospitals in the Calgary health region, two hospices, and a tertiary palliative care unit. Measurements: Descriptive data, including proportion of deaths involving palliative sedation therapy, number of criteria documented, midazolam dose/duration, concurrent symptom management therapies, and referrals to spiritual care, psychology, or social work. Results: CPST occurred in 602 out of 14,360 deaths (4.2%). Full adherence to criteria occurred in 7% of cases. The most commonly missed criteria were: a "C2" goals-of-care designation order (comfort care focus in the imminently dying) (84%) and documentation of imminent death in the chart (55%). Concurrent medical therapies included opioids in 98% of cases and intravenous hydration in 85% of cases. Few referrals were made to multidisciplinary care teams. Conclusions: We found low adherence to palliative sedation guidelines. This may reflect the perception that some criteria are redundant or clinically unimportant. Future work could include a study of barriers to guideline uptake, and guideline modification to provide direction on concurrent therapies and multidisciplinary team involvement.
