Purpose: There is controversy as to whether vitamin D deficiency is associated with increased mortality from coronavirus infection. The aim of the study was to assess the relationship between vitamin D levels and 30-day mortality in hip fracture patients co-infected with COVID-19.

Methods: This was a national observational audit conducted between 23 March 2020 (start of UK lockdown) and 31st December 2020. The cohort consisted of patients aged >60 years presenting with a hip fracture. Patients were included if they had a vitamin D level done during the admission episode, diagnosis of COVID-19 infection via a viral reverse transcriptase PCR swab, and a hip fracture. There were 517 patients included in the study from 43 different hospital trusts. The primary outcome measure was 30-day mortality. Secondary outcomes were the percentage of patients who had vitamin D deficiency, the percentage of patients who were prescribed Vitamin D, and the impact of vitamin D prescribing on mortality

Results: Vitamin D deficiency was not associated with a higher 30-day mortality. Low serum vitamin D was observed in 56% of the patients on admission. Vitamin D was prescribed prior to admission in 28% and during admission in a further 49%. Pre-hospital vitamin D therapy reduced the chance of vitamin D deficiency. Starting vitamin D before or on admission did not affect the mortality rates.

Conclusion: Vitamin D deficiency was common, but not associated with a higher 30-day mortality in the hip fracture population co-infected with COVID-19.
