Clinical characteristics and prognostic factors among hospitalized patients with substance use disorders: Findings from a retrospective cohort study of a Canadian inpatient addiction medicine service.

INTRODUCTION: Inpatient addiction medicine services (AMS) were developed in response to the growing needs of hospitalized individuals with substance use disorders (SUDs). AMS aim to enable timely initiation of pharmacologic treatment, build hospital capacity to support patients who use substances, and facilitate transition to community services. As an emerging service being adopted in hospitals across North America, the model of care, populations served, substance use trends, and clinical trajectory has not been widely described. This work aims to characterize patients accessing care through the AMS, establishing predictors for clinical trajectories in hospital including patient-initiated discharge (PID) and hospital re-admission. METHODS: Using a retrospective cohort design, we describe all patients seen by the AMS between 2018 and 2022 across four hospitals in Hamilton, Ontario. Patients seen by AMS were hospitalized and qualified for a SUD based on DSM-V criteria. The study used descriptive statistics to describe the cohort, where appropriate adjusted time-to-event survival models were constructed to identify predictors for hospital re-admission. RESULTS: Patients seen by the AMS (n = 695) frequently lacked access to primary care (47.0 %) and less than half (44.3 %) were receiving community addiction services on admission. The majority met criteria for opioid use disorder (OUD), with injecting being the primary consumption route (54.8 %). Patients exhibited high acuity, with 34.2 % requiring critical care measures. Provision of OAT substantially increased to 77.9 % of patients (29 % on admission). PID occurred in 17.8 % of patients and was significantly associated with an admitting diagnosis of suicidal ideation, infection, heart failure, and distinct substance use profiles including methamphetamine, fentanyl, and heroin use (p < 0.05). PID conferred a 66 % increased risk for re-admission (Hazard-Ratio: 1.66; 95 % CI: 1.08, 2.54; p = 0.02). CONCLUSION: Patients served by AMS primarily include individuals with OUD presenting with the associated medical complications and substantial deficits in the social determinants of health (e.g., high housing insecurity, poverty, and disability). PID occurs among 1 in 5 people and is associated with higher rates of re-admission. By identifying individuals at higher risk of adverse outcomes, these results provide an opportunity to improve outcomes in this high-risk, high-vulnerability population.

Parental Leave Policies in Canadian Residency Education.

BACKGROUND: In recent decades, the gender makeup of Canadian medical residents has approached parity. As residency training years coincide closely with childbearing years and paid parental leave is associated with numerous benefits for both parents and children, it is important for there to be clarity about parental leave benefits. OBJECTIVES: We aimed to conduct a comprehensive review of maternity and parental leave policies in all residency education programs in Canada, to highlight gaps that might be improved or areas in which Canadian programs excel. METHODS: We searched websites of the 8 provincial housestaff organizations (PHOs) for information regarding pregnancy workload accommodations, maternity leave, and parental leave policies in each province in effect as of January 2020. We summarized the policies and analyzed their readability using the Flesch Reading Ease. RESULTS: All Canadian PHOs provide specific accommodations around maternity and parental leave for medical residents. All organizations offer at least 35 weeks of total leave, while only 3 PHOs offer extended leave of about 63 weeks, in line with federal regulations. All but 2 PHOs offer supplemental income to their residents, although not for the full duration of offered leave. All PHOs offer workplace accommodations for pregnant residents in their second and/or third trimester. CONCLUSIONS: Although all provinces had some form of leave, significant variability was found in the accommodations, duration of leave, and financial benefits provided to medical residents on maternity and parental leave across Canada. There is a lack of clarity in policy documents, which may be a barrier to optimal uptake.

Converting to Connect: A Rapid RE-AIM Evaluation of the Digital Conversion of a Clerkship Curriculum in the Age of COVID-19.

BACKGROUND: With the advent of the 2019 coronavirus pandemic, a decision was made to remove medical students from clinical rotations for their own safety. This forced students on a core emergency medicine (EM) rotation at McMaster University to immediately cease all in-person activities. An urgent need for a virtual curriculum emerged. METHODS: A virtual curriculum consisting of asynchronous case-based learning on Slack, ask-me-anything webinars, and online e-modules was created to fill the need. We describe a program evaluation using the RE-AIM framework and a social networking analysis of participants. RESULTS: Medical students (n = 23) and 11 facilitators (five residents, six faculty members) participated in this pilot study. Faculty members sent a mean (±SD) of 115 (±117) messages (n = 6), and mean (±SD) message counts for students and residents were 49.96 (±25; n = 23) and 39 (±38; n = 5), respectively. A total of 62,237 words were written by the participants, with a mean of 1,831 per person. Each message consisted of a mean (±SD) of 25 words (±29). Students rapidly acquitted themselves to digital technology. Using the RE-AIM framework we highlight the feasibility of a virtual curriculum, discuss demands on faculty time, and reflect on strategies to engage learners. CONCLUSIONS: The use of asynchronous digital curricula creates opportunities for faculty-resident interaction and engagement. We report the successful deployment of a viable model for undergraduate EM training for senior medical students in the COVID-19 era of physical distancing.
