Effect of the COVID-19 lockdown on disease recognition and utilisation of healthcare services in the older population in Germany: a cross-sectional study

BACKGROUND: There is little evidence about the utilisation of healthcare services and disease recognition in the older population, which was urged to self-isolate during the COVID-19 lockdown. OBJECTIVES: We aimed to describe the utilisation of physician consultations, specialist referrals, hospital admissions and the recognition of incident diseases in Germany for this age group during the COVID-19 lockdown. DESIGN: Cross-sectional observational study. SETTING: 1,095 general practitioners (GPs) and 960 specialist practices in Germany. SUBJECTS: 2.45 million older patients aged 65 or older. METHODS: The number of documented physician consultations, specialist referrals, hospital admissions and incident diagnoses during the imposed lockdown in 2020 was descriptively analysed and compared to 2019. RESULTS: Physician consultations decrease slightly in February (−2%), increase before the imposed lockdown in March (+9%) and decline in April (−18%) and May (−14%) 2020 compared to the same periods in 2019. Volumes of hospital admissions decrease earlier and more intensely than physician consultations (−39 versus −6%, respectively). Overall, 15, 16 and 18% fewer incident diagnoses were documented by GPs, neurologists and diabetologists, respectively, in 2020. Diabetes, dementia, depression, cancer and stroke were diagnosed less frequently during the lockdown (−17 to −26%), meaning that the decrease in the recognition of diseases was greater than the decrease in physician consultations. CONCLUSION: The data suggest that organisational changes were adopted quickly by practice management but also raise concerns about the maintenance of routine care. Prospective studies should evaluate the long-term effects of lockdowns on patient-related outcomes.
