[Translated article] Has the COVID-19 lockdown influenced the mortality of hip fracture? Analysis of one-year mortality

INTRODUCTION AND OBJECTIVES: The main objective of this study is to analyse the one-year mortality in patients with intracapsular hip fracture who were admitted during severe social confinement in the first months of the COVID-19 lockdown and compare it with previous years. MATERIAL AND METHODS: Retrospective observational study in which a cohort from March 14 to June 21, 2020 (pandemic group, n = 62) was compared with a control cohort on the same dates in the years 2017, 2018 and 2019 (control group, n = 172). Thirty-day-mortality and one-year-mortality, orthopaedic complications, ASA grade, comorbidities, diagnosis and treatment, time to surgery and mean stay were measured. RESULTS: No significant differences were found in 30-day mortality (p = 0.156; 9.7% compared to 4.7%) or in one-year mortality (p = 0.47) between the pandemic group (21%) and the control one (16.9%). A decrease in surgical delay and mean stay was observed in the pandemic group, although without statistical significance. CONCLUSION: The State of Alarm modified the distribution of the type of hip fracture with a predominance of intracapsular fracture. Maintaining the same hospital management as prior to the pandemic period made it possible not to increase 30-day mortality and one-year mortality in patients with intracapsular hip fracture.
