Primary Care Clinical Volumes, Cholesterol Testing, and Cardiovascular Outcomes.

BACKGROUND: It is unknown whether the annual number of primary care physician (PCP) unique outpatient assessments, which we refer to as clinical volume, translates into better cardiovascular preventive care. We examined the relationship between PCP outpatient clinical volumes and cholesterol testing and major adverse cardiovascular event rates among guideline-recommended eligible patients. METHODS: This was a retrospective cohort study conducted as part of the Cardiovascular Health in Ambulatory Care Research Team (CANHEART) cohort, a population-based cohort of almost all adult residents of Ontario, Canada, followed from 2008 to 2012. For each clinical volume quintile, we compared cholesterol testing and major adverse cardiovascular events, defined as time to first event of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. RESULTS: The 10,037 PCPs evaluated had an annualized median volume of 2303 clinical encounters (IQR 1292-3680). Among 4,740,380 patients, 84% underwent guideline-concordant cholesterol testing at least once over 5 years, ranging from 73% with the lowest clinical volume quintile physicians to 86% with the highest. After multivariable adjustment, there was a 10.5% relative increase in the probability of cholesterol testing for every doubling of clinical volumes (95% CI 9.7-11.4; P < 0.001). Patients treated by the lowest volume quintile physicians had the highest rate of major adverse cardiovascular outcomes (compared with the highest volume quintile physicians: adjusted HR 1.15, 95% CI 1.10-1.21; P < 0.001). CONCLUSIONS: Patients of physicians with the lowest clinical volumes received less frequent cholesterol testing and had the highest rate of incident cardiovascular events. Further research investigating the drivers of this relationship is warranted.

Preparing for Surgery Observerships During Medical School: A Cross-Sectional Study.

OBJECTIVE: Observerships are self-organized experiences for medical students to accompany a university affiliated physician in a clinical setting. Our study's objective was to evaluate year 1 and 2 medical students' experience with and preparation methods for surgery observerships at a Canadian medical school. DESIGN: A cross-sectional online survey of preclerkship students, capturing resources used to prepare for observerships, types of observerships completed, and reasons for participating. Descriptive statistics were used to report demographics, observership types, and preparation methods. Gender differences in observership types were analyzed using two-way analysis of variance. SETTING: Queen's University. PARTICIPANTS: All preclerkship medical students (years 1 and 2) were invited to participate. RESULTS: Of the 64 respondents (64/202), 46 (71.9%) were female and 53 (82.8%) participated in at least 1 surgery observership. The most common observerships were General Surgery (53.8%, 28/53), Obstetrics and Gynecology (50.1%), and Orthopedic Surgery (37.7%). There was no significant difference between genders in the number of surgery versus nonsurgery observerships. Common reasons for participating in surgery observerships included: "may not have opportunities in the future" (52.8%) and "rule in surgery as a career" (50.9%). Majority (64.2%) of students prepared for observerships and spent on average 1.3 ± 0.6 hours preparing. Commonly used resources included class notes (82.4%), and online videos (73.5%). Most respondents (91.0%) who prepared noted preparation was associated with a positive learning experience. Most respondents (67.1%) reported a lack of resources provided on how to prepare. CONCLUSIONS: Preparing for observerships was associated with a positive experience and most students used class notes and online videos. There was a lack of instructions and resources on how to prepare. Developing appropriate resources for pre-clerkship medical students to prepare may improve overall experiences and increase interest in surgery.
