Abstract
BACKGROUND: The COVID-19 pandemic led to a decrease in the provision and use of healthcare. Few studies reported reasons for these changes. We aimed to (i) describe the frequency of changes in healthcare utilization in those requiring ongoing treatment, and possible reasons thereof, and (ii) assess characteristics associated with change, during the second wave of the pandemic. METHODS: Participants from the Corona Immunitas e-cohort study (age ≥20 years) completed monthly questionnaires between September 2020 and February 2021. We used descriptive and bivariate statistics, to compare participants reporting a change in healthcare utilization with those who reported no change. We used negative binomial regression to explore characteristics associated with the number of changes. RESULTS: In total, 3190 adults from nine research sites participated in this study. One-fifth (N = 658, 21%) reported the need for regular treatment. About 14% of them reported a change in healthcare utilization, defined as events in which participants reported that they changed their ongoing treatment, irrespective of the reason. Reported reasons for change were medication changes and side-effects, specifically for hypertension, or pulmonary embolism treatment. Females were more likely to report changes in healthcare utilization (Incidence Rate Ratio (IRR)=1.69, p = 0.030), and those with hypertension were least likely to report changes (IRR=0.45, p = 0.092). CONCLUSIONS: Among those who needed regular treatment, few reported changes in healthcare utilization. The importance of continuity of care for females and chronic diseases other than hypertension must be emphasized. This calls for tailored measures considering gender disparities. KEY MESSAGES: • Changes in healthcare utilization were more pronounced in women than men during the Covid-19 pandemic. • Tailored disease surveillance is necessary considering gender disparities and chronic diseases other than hypertension.
