The COVID-19 pandemic and the countermeasures taken form a threat to the physical and mental health of the population, especially for more vulnerable groups. In this study, which is part of the Integrated Health Monitor COVID-19, the impact of the COVID-19 pandemic on the healthcare use of the Dutch population and specific vulnerable groups was examined.

In this study two data-sources were combined. The first consists of electronic patient records of general practices (GP) participating in the Nivel Primary Care Database. These records are representative of the Dutch population and provide insight into acute complaints, chronic conditions, medication prescriptions and primary care use. For the current study, primary care use in pre-COVID years (2018 and 2019) was compared to that in 2021. This data was coupled with microdata from Statistics Netherlands, containing such information as socio-economic status and migration background. Analyses were conducted using longitudinal mixed-effects regression models.

Results show that risk factors play a role in the utilization of primary care. Women and those with a low household income visited the GP more often for mental complaints. Individuals with a migrant background visited the GP more often for coughing, fatigue, and social problems. Those with pre-existing chronic physical conditions were seen less often by their GP for shortness of breath. Among those with pre-existing mental problems GPs more often registered shortness of breath, yet less problems with access to care or social problems.

Combining GP registry data with relevant background data has deepened our understanding of changes in health problems and healthcare use among the general population during the COVID-19 pandemic. This study provides insight into how specific vulnerable groups are affected more strongly, and emphasizes the importance of monitoring these groups during a health crisis.
