Retrospective 517 hip fracture patients in the UK with vitamin D levels measured during COVID-19 admission, not showing significant differences in mortality for supplementation in unadjusted analysis with no group details and subject to confounding by indication. There was also no significant effect based on deficiency.
This is the 63rd of 115 COVID-19 controlled studies for vitamin D, which collectively show efficacy with p<0.0000000001 (1 in 30 sextillion). 27 studies are RCTs, which show efficacy with p=0.00002. This study is excluded in the after exclusion results of meta analysis: unadjusted results with no group details; substantial unadjusted confounding by indication likely.
risk of death, 9.4% lower, RR 0.91, p = 0.67, treatment 34 of 138 (24.6%), control 31 of 114 (27.2%), NNT 39, prescribed by GP.
risk of death, 30.5% lower, RR 0.70, p = 0.10, treatment 45 of 238 (18.9%), control 31 of 114 (27.2%), NNT 12, started after admission, late treatment result.
risk of death, 12.5% lower, RR 0.87, p = 0.51, high D levels (≥25nmol/L) 70 of 346 (20.2%), low D levels (<25nmol/L) 40 of 144 (27.8%), adjusted per study, inverted to make RR<1 favor high D levels (≥25nmol/L), odds ratio converted to relative risk, outcome based on serum levels.

Coronavirus in HIP Fractures CHIP 2: Is Vitamin D Deficiency Associated with Increased Mortality from COVID-19 Infections in A Hip Fracture Population?

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 30day 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 31 st 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.
