AB092. SOH22ABS033. The effect of coronavirus disease 2019 (COVID-19) on 30-day mortality rates amongst Irish fragility hip fracture patients

Background: Fragility hip fracture patients are vulnerable to high rates of short-term mortality, which may have been exacerbated by the coronavirus disease 2019 (COVID-19) pandemic. This study will assess the effect of COVID-19 on 30-day mortality rates amongst a group of Irish hip fracture patients. Additionally, patient demographics, length of stay, admission haematological parameters, fracture type and surgical procedure will be assessed. Methods: A multicentre, observational, retrospective study of hip fracture patients (n=1,017) admitted to six Dublin teaching hospitals during the COVID-19 pandemic was performed. For comparative purposes, equivalent data was retrospectively collected relating to hip fracture patients admitted to the same teaching hospitals in 2019. Results: There were 481 patients admitted during the 2020 study period, compared with 536 patients in 2019. Approximately sixty-six percent of patients were female and the mean patient age was 77.6 years. Recorded 30-day mortality rates were 5.4% in 2020 and 4.3% in 2019 (P=0.338). There was an insignificant decrease in patients’ mean length of stay (17.85 days in 2020 vs. 18.82 days in 2019; P=0.106). Advancing age (P=0.021), male gender (P=0.019), low admission haemoglobin (P=0.024) and high admission white cell count (P=0.019) were all associated with 30-day mortality. Conclusions: We found no significant difference in 30-day mortality rates amongst our cohort of hip fracture patients during the COVID-19 pandemic. Advancing age, male gender, anaemia at admission and leucocytosis at admission were associated with increased 30-day mortality. The continuation of COVID-19 related safety protocols in the treatment of hip fracture patients is essential in maintaining a safe hip fracture service.
