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.

Clinical presentation and in-hospital outcomes of older patients hospitalized with COVID-19 in Montreal, Canada: a retrospective review (preprint)

ABSTRACT Background Older adults are more vulnerable to severe infection and mortality due to COVID-19. They often have atypical presentations of the disease without respiratory symptoms, which makes early diagnosis clinically challenging. We aimed to compare the baseline characteristics, presentation, and disease course of older and younger patients hospitalized with COVID-19. Methods The charts of 429 consecutive patients hospitalized in Montreal, Canada, with PCR-confirmed COVID-19 were retrospectively reviewed. Baseline health, presentation, in-hospital complications, and outcomes were recorded. Desegregation by age was performed to compare older (≥70) versus younger (<70) individuals. Results Older patients presented with more comorbidities compared to younger patients as captured by the Charlson Comorbidity Index (mean 6 vs 2), including higher rates of cardiovascular, cerebrovascular, chronic obstructive pulmonary, and chronic kidney disease. Older patients were less likely than younger patients to present with cough (27% vs 47%) or dyspnea (33% vs 48%). Fifty-two (52%) had no respiratory symptoms on presentation compared to 32% in the younger group (p<0.001); however, they were more likely to present with geriatric syndromes such as delirium (29% vs 7%), functional decline (14% vs 0.6%), or falls (15% vs 5%). Twelve (12%) of older patients presented with a geriatric syndrome as their sole symptom compared to 3% in the younger group (p=0.002). Older adults were more likely to develop acute kidney injury (35% vs 22%), malnutrition (9% vs 4%), delirium (29% vs 17%) and hypernatremia (32% vs 17%). They had higher in-hospital mortality (33% vs 13%, p<0.001). Discussion Older adults presenting to hospital with COVID-19 commonly have no respiratory symptoms and can present with only a geriatric syndrome. A new geriatric syndrome in an older person should trigger isolation and evaluation for COVID-19. Furthermore, older adults are particularly vulnerable to complications related to dehydration, warranting early initiation of multidisciplinary care.
