[Effects of the COVID-19 pandemic on the course of geriatric trauma patients with proximal femoral fractures].

Background/objective: In 2020 the COVID-19 pandemic posed a major challenge to the healthcare system. The hypothesis is that the COVID-19 pandemic in 2020 had an impact on the care of older adults with proximal femoral fractures due to resource scarcity, regardless of whether or not the patient was infected.

Material And Methods: This study analyzed the data of 87 hospitals which entered 15,289 patients in the Geriatric Trauma Register ("AltersTraumaRegister DGU®", ATR-DGU) in Germany in 2019 and 2020. In this study we analyzed the influence of the COVID-19 pandemic on the inpatient treatment of hip fractures as well as the mid-term follow-up during the first 120 days. For the main analysis, we compared patients documented during the COVID-19 pandemic in 2020 (April-December) with a control group in 2019 (April-December). Additionally, we performed a subgroup analysis of the periods with high COVID-19 incidence rates.

Results: Between 2019 and 2020 a total of 11,669 patients (2020: n = 6002 patients vs. 2019: n = 5667 patients) were included in this study. Only minor differences were found between the patients treated during the pandemic; however, when the COVID-19 incidence in Germany was greater than 50/100,000 residents, significantly fewer patients (p < 0.001) were discharged to a geriatric rehabilitation ward (27.2% vs. 36.3%) and an increased mortality rate during inpatient treatment was determined (8.4% vs. 4.6%) (p < 0.001).

Discussion: The healthcare system was able to respond to the pandemic and patients' clinical courses were not impaired as long as the incidences were low. Nevertheless, the healthcare system reached its limits in times of higher incidence, which was also directly reflected in the patient outcome, mortality and place of discharge.
