Hip Fracture Surgery Volumes Among Individuals 65 Years and Older During the COVID-19 Pandemic.

Hip fractures in individuals 65 years or older are common (>250 000 per year in the US) and consequential (1-year mortality rate, 12%-37%). Prior studies of orthopedic trauma (ie, fractures) in the general population documented a decline at the beginning of the COVID-19 pandemic in March-April 2020, followed by a return to baseline by summer 2020 once shelter-in-place orders were lifted. We assessed hip fracture surgery volumes among older individuals during the pandemic. This study was approved by the Kaiser Permanente (KP) Institutional Review Board with exemption of informed consent. We used data from the KP Hip Fracture Registry (a surveillance tool with 100% coverage) along with membership data and administrative claims. Patients aged 65 years or older who underwent hip fracture surgery between January 1, 2018, and September 26, 2021, in a California KP hospital (n = 31) were included. Patients (n = 18 288;mean age, 82 years;70.0% female;7.9% Asian, 5.1% Black, 12.4% Hispanic, 0.7% Native American, 74.0% White;83% with =3 comorbidities) had similar characteristics in the pandemic and historical comparison periods.
