Mortality and Incidence Rate of SARS-CoV-2 (COVID-19) Infection in Patients Admitted and Operated for Hip Fracture during SARS-CoV-2 pandemic in a London Hospital

Objective We are doing a study on patients admitted with hip fractures to determine the impact of COVID-19 on a vulnerable patients group in the United Kingdom. This will help us in making informed decisions about restarting elective surgical services and expanding trauma surgical services. The objectives of the study are: 1) to find the incidence of COVID-19 in patients admitted with hip fractures; 2) To find the 30-day mortality in patients operated with hip fractures; 3) To find the 30-day mortality of patients with hip fracture and COVID 19; and 4) to compare this data with the mortality in hip fractures in previous years. Methods This is a single-center, observational, retrospective, cohort study involving 65 patients who were admitted in our trust with hip fractures. Besides epidemiological data, patient records were followed-up for 14 days to look for COVID positive polymerase chain reaction (PCR) swabs, and the patient records were followed-up for 30 days to look for mortality. Results A total of 64% of the patients had no significant comorbidity. The incidence of hospital-acquired COVID-19 infections in our trust was 9%. Overall, the 30-day mortality was of 15%. Mortality was much higher in COVID positive patients (40%) and in patients with “very high risk” (63%) operated during this period. Conclusion It should be safe to start elective surgery in patients with low, moderate and high risk without an appreciable rise in mortality. We will need more data to understand the impact of COVID-19 on very high risk patients.
