COVID-19 and Proximal Femur Fracture in Older Adults—A Lethal Combination? An Analysis of the Registry for Geriatric Trauma (ATR-DGU)

OBJECTIVES: COVID-19 can be a life-threatening illness, especially for older patients. The COVID-19 outbreak created a dramatic organizational challenge in treating infected patients requiring surgical treatment, like those suffering a proximal femur fracture, in a pandemic setting. We investigate the impact of a COVID-19 infection in patients with a proximal femur fracture not only on mortality but also on quality of life (QoL), length of stay, and discharge target. DESIGN: Retrospective cohort analysis from July 1, 2020, to December 31, 2020. The Registry for Geriatric Trauma collected the data prospectively. Patient groups with and without COVID-19 infection were compared using linear and logistic regression models. SETTING AND PARTICIPANTS: Retrospective multicenter registry study including patients aged ≥70 years with proximal femur fracture requiring surgery from 107 certified Centers for Geriatric Trauma in Germany, Austria, and Switzerland. MEASURES: The occurrence and impact of COVID-19 infection in patients suffering a proximal femur fracture were measured regarding in-house mortality, length of stay, and discharge location. Moreover, QoL was measured by the validated EQ-5D-3L questionnaire. RESULTS: A total of 3733 patients were included in our study. Of them, 123 patients tested COVID-19 positive at admission. A COVID-19 infection resulted in a 5.95-fold higher mortality risk (odds ratio 5.95, P < .001], a length of stay prolonged by 4.21 days [regression coefficient (β) 4.21, P < .001], a reduced QoL (β −0.13, P = .001), and a change in discharge target, more likely to their home instead of another inpatient facility like a rehabilitation clinic (P = .013). CONCLUSIONS AND IMPLICATIONS: The impact of a COVID-19 infection in patients suffering a proximal femur fracture is tremendous. The infected patients presented a dramatic rise in mortality rate, were significantly less likely to be discharged to a rehabilitation facility, had a longer in-hospital stay, and a reduced QoL.
