Length of hospital stay and mortality of hip fracture surgery in patients with Coronavirus disease 2019 (COVID-19) infection: A systematic review and meta-analysis

摘要

Background: Coronavirus disease 2019 (COVID-19) patients who undergo hip fracture surgery are expected to have worse outcomes because they are vulnerable to developing COVID-19-associated complications. The present review attempted to assess the in-hospital and 30-day mortality rates as well as the length of hospital stay in patients with COVID-19 infection who had hip fracture surgery. Methods: Two authors independently searched Google Scholar, PubMed, Web of Knowledge, SCOPUS, and Embase, based on the MeSH-matched scientific keywords. The nine-star Newcastle-Ottawa Scale (NOS) scoring system was employed to assess the methodological quality of all eligible studies. Results: Eleven cohort studies that included 336 patients comprised the study. Three studies reported in-hospital mortality. Eight studies reported 30-day postoperative mortality. The pooled in-hospital mortality rate was 29.8% (95% CI: 26.6%-35.6%). The pooled 30-day postoperative mortality rate was 35.0% (95% CI: 29.9%-40.5%). The mean hospital stay was 11.29 days (95% CI: 10.65 days-11.94 days). Conclusions: The rates of in-hospital and 30-day mortality in COVID-19 patients who undergo hip fracture surgery is high. These data suggest delaying hip fracture surgery until COVID-19 infection of the patients is controlled.
