2199 The prevalence of pre-admission vitamin D levels in the management and outcomes of proximal femur fractures

Abstract Introduction The aim of this study was to examine the prevalence of vitamin D deficiency in elderly patients with fragility fractures of the hip by estimating 25-hydroxyvitamin D levels, whether low levels of Vitamin D at the time of admission affects the functional outcomes and mortality at 28 day and one year. Methods A retrospective study of all the patients admitted with a fracture neck of femur from Jan 2018 to March 2021 was carried out. The data was obtained from NHFD (National Hip Fracture Database) and Medway software. A total of 1221 patients were admitted during this period. Patient demographics including age, sex, fracture pattern, Vitamin D levels at the time of admission, function at 120 days, mortality at one month and one year were calculated. Results Of the 1221 patients, 106 patients did not have the Vit D levels checked at the time of admission. The average age was 81.91 (range-60 to 108). There were 845 (70%) females and 376 (30%) males. The serum Vit D levels were low in 611 (55.3%) patients. The mobility in patients with Vit D deficiency 261 (40.9%) has dropped significantly in the 3 months after surgery for fractures of proximal femurs. The 28 day and one year mortality was 6.74% and 30.3% compared to 4.7% and 27.3% for those with low and normal levels of vitamin D respectively. Patients with low Vit D levels at the time of admission with proximal femur fractures has got higher 28 day and one year mortality rates compared to those with normal levels. Conclusion Our study showed that low levels of Vitamin D at the time of admission with proximal femur fractures are associated with poor functional mobility, higher perioperative and one year mortality.
