Hip fracture care during Covid-19: a regional trauma centre's experience.

Introduction: The Covid-19 pandemic has caused worldwide upheaval from early 2020. Trauma and orthopaedic services are no different. A fundamentally important and significant portion of trauma services is the treatment of fragility fractures of the proximal femur, otherwise known as hip fractures. The hip fracture "Blue book Standards", the key performance indicators (KPIs) associated with appropriate hip fracture care are challenging during non-crisis times. We aim to review Blue Book compliance during the Covid-19 crisis and review outcomes of hip fractures, including Covid-19 infection rates.

Methods: We retrospectively reviewed IHFD data to collection demographic data, IHFD standards of care, 30-day mortality rates and complications between 23rd March and 20th May 2020 and 2019. Covid-19 rates in 2020 were also recorded.

Results: A total of 36 hip fractures were recorded in 2020, compared with 45 in 2019, resulting in a 20% reduction in presentations. Thirty-day mortality in hip fractures during the Covid-19 crisis was 8.3% compared with 2.2% in 2020. Covid-19 infection was statistically associated with 30-day mortality in the 2020 cohort. Statistically significant improvements in time-dependent KPIs (time to ward and time to surgery) were noted in the 2020 cohort.

Conclusions: Despite improvements in hip fracture care KPIs, the Covid-19 crisis was associated with increased 30-day mortality in hip fracture patients. A positive Covid-19 swab was associated with higher mortality. These observations are of paramount importance to ensure adequate service planning and provision in the face of a potential "second wave" of Covid-19 infections leading into the winter months of 2020.
