Emergency department utilization and hospitalizations for ambulatory care sensitive conditions among unattached people actively seeking a primary care provider during the COVID-19 pandemic: a retrospective cohort study (preprint)

Background: Primary care (PC) attachment improves healthcare access and prevention and management of chronic conditions. Yet, growing proportions of Canadians are unattached, signing-up on provincial waitlists. Understanding variations in healthcare utilization during COVID-19, and among potentially vulnerable unattached patients, is needed. This study compares emergency department (ED) utilization and hospitalization among those on and off a provincial PC waitlist, during the first two waves of COVID-19. Methods: Waitlist and administrative health data were linked to describe persons ever/never on the waitlist between January 1, 2017, and December 24, 2020. ED utilization and ambulatory care sensitive conditions (ACSC) hospitalization rates by current waitlist status were quantified from physician claims and hospitalization data. Relative differences during COVID-19 first and second waves were compared with the previous year. Results: During the study period, 100,867 Nova Scotians (10.1%) were on the waitlist. Those on the waitlist had higher ED utilization and ACSC hospitalizations. ED utilization was higher overall for individuals [≥]65 years and females; lowest during first two COVID-19 waves; and differed more by waitlist status for those <65 years. ED contacts and ACSC hospitalizations decreased during COVID-19 relative to the previous year, and for ED utilization this difference was more pronounced for those on the waitlist. Interpretation: Nova Scotians seeking PC attachment utilize hospital-based services more frequently than those not on the waitlist. Both groups had lower utilization during the COVID-19 pandemic than the year before. The degree to which forgone services produces downstream health burden remains to be seen.

COVID-19 – An Opportunity to Improve Access to Primary Care Through Organizational Innovations? (preprint)

Background: COVID-19 catalyzed a rapid and substantial reorganization of primary care, accelerating the spread of existing strategies and fostering a proliferation of innovations. Access to primary care is an essential component of a health care system, particularly during a pandemic. We describe organizational innovations aiming to improve access to primary care and related contextual changes, during the first year of the COVID-19 pandemic in two Canadian provinces, Quebec and Nova Scotia. Methods: We conducted a multiple case studies, based on 63 semi-structured interviews (n=33 in Quebec, n=30 in Nova Scotia) conducted between October 2020 and May 2021 and a review of related internal documents from both jurisdictions. We recruited a diverse range of provincial and regional stakeholders (e.g., policymakers, decision-makers, family physicians, nurses) involved in reorganizing primary care during COVID-19 using purposeful sampling (e.g., based on role, region). Interviews were transcribed verbatim and thematic analysis was conducted in NVivo12. Emerging results were discussed by team members to identify salient themes and organized into logic models. Results: We identified and analyzed six organizational innovations. Four of these - centralized public online booking systems, centralized access centers for unattached patients, and interim primary care clinics for unattached patients and community connector to health and social services for older adults – pre-dated COVID-19 but were accelerated by the pandemic context. The remaining two innovations were created to specifically address pandemic-related needs: COVID-19 hotlines and COVID dedicated primary healthcare clinics. Innovation spread and proliferation was influenced by several factors such as a strengthened sense of community amongst providers, decreased patient demand at the beginning of the first wave, renewed policy and provider interest in population-wide access (versus attachment of patients only), suspended performance targets (e.g., continuity ≥80%) in Quebec, in modality of care delivery, modified fee codes, and greater regional flexibility to implement tailored innovations. Conclusion: COVID-19 accelerated the uptake and creation of organizational innovations to potentially improve access to primary healthcare, removing, at least temporarily, certain longstanding barriers. Many stakeholders believed this reorganization would have positive impacts on access to primary care after COVID-19. Further studies should analyze the effectiveness and sustainability of innovations adapted, developed, and implemented during the COVID-19 pandemic.
