Primary care insights on the management of diabetes: results from a mixed method study of care changes and impacts during the COVID-19 pandemic.

BACKGROUND

In Canada, primary care manages most diabetes care. The COVID-19 pandemic disrupted primary care, reducing access to care and monitoring.

OBJECTIVES

We aim to describe changes in diabetes monitoring during the first 21 months of the pandemic, patients' experiences with these changes, and impact on HbA1c and blood pressure (BP) control.

METHODS

We conducted a two-phase mixed methods study: (i) A retrospective pre-post cohort study using de-identified electronic medical record data to compare HbA1c and BP measurement frequency and results in diabetic patients prepandemic (22 June 2018 to 12 March 2020) and during the pandemic (13 March 2020 to 3 December 2021); (ii) A qualitative descriptive analysis using semistructured interviews to understand patient experiences navigating diabetes care during the pandemic.

RESULTS

The cohort included 84 617 patients with validated diabetes case definition. Proportion of patients with <1 HbA1c test increased by 10% during the pandemic. For those with ≥1 test, mean HbA1c remained unchanged [mean (SD) HbA1cPre: 7.2 (1.3); HbA1cDuring: 7.2 (1.3); P = .51]. Proportion of patients with <1 BP measurement increased by 23%. For those with ≥1 measurement, mean BP remained clinically similar [mean (SD) sBPPre: 131.8 (13.7); sBPDuring: 132.9 (15.2); P < .01. Mean dBPPre: 74.9 (8.6); dBPDuring: 75.1 (9.1); P = .63]. Nineteen participants were interviewed, discussing virtual care, challenges with self-monitoring, and self-management strategies.

CONCLUSIONS

Mean HbA1c and BP values remained clinically stable during the pandemic despite reductions in monitoring frequency, likely due to continuity of care and patient self-management. Future research should evaluate a de-intensified frequency of diabetes monitoring and address care gaps.
