Introduction: There are suggestions that elective surgery performed during the incubation period of COVID-19 infection may cause an immediate impairment of cell-mediated immunity, leading to high morbidity and mortality. However is contrasting data about the associated mortality. Since the outbreak, our unit has maintained a prospective database recording Trauma and Orthopaedic surgical activity. Our aim was to share our experience of the first 3 months with prospective data on outcome of essential surgery during the covid-19 peak. Our focus in this report was on the mortality rate as services begin to open. Methods: We prospectively collected data during the peak of the pandemic in the UK, for fracture neck of femur patients (NOF) the most commonly performed surgical procedure and the most vulnerable during this period. We compared this Covid-19 cohort of NOFs against a cohort of NOF's during the same time in 2019 and another cohort of NOF's in 2020 outside the lockdown period to compare mortality rates and give a broader perspective.
Results: During the period March 1, 2020 to May 31, 2020, total of 206 patients were operated. Ninety-four fracture NOF and another one hundred twelve essential surgical procedures were performed. In the NOF cohort, there were nine patients that died. Three of them were covid-19 positive, one was not tested and the rest five were covid-19 negative. There was no mortality reported in the non NOF group. Conclusion: In our unit, during the lock down period, mortality rate in patients undergoing fracture NOF was not significantly different from a similar cohort earlier in the year and similar period last year. We have not observed any mortality, to date in the Non NOF procedures carried out.
