Intervention for Increasing Vitamin D Supplementation in a Deficient Rehabilitation Population: Outcomes of a Quality Improvement Initiative.

Abstract

Vitamin D deficiency (VDD) is highly prevalent and increases the risk of osteoporosis, falls, and fractures. Patients in acute inpatient rehabilitation have several risk factors for VDD, the adverse effects of which may hinder long-term functional gain. To evaluate the prevalence of and risk factors for VDD in patients admitted to acute inpatient rehabilitation and to evaluate the efficacy of a standardized vitamin D screening and supplementation protocol. Prospective cohort study as part of a quality improvement initiative. An academic, freestanding acute inpatient rehabilitation hospital. Patients consecutively admitted over a 4-month period between November 2014 and February 2015 (n=128 pre-intervention and n=129 post-intervention). Universal screening of vitamin D level on admission followed by utilization of a standard supplementation protocol. Vitamin D insufficiency (VDI) and VDD prevalence along with screening, and supplementation rates. Preintervention, 10.2% of patients were screened for VDD, with 23.1% VDI and 46.2% VDD. Postintervention, 89.9% were screened, with 31.9% VDI and 47.4% VDD. 6.3% of all patients were supplemented on vitamin D preintervention compared to 53.5% postintervention. In multivariate analyses, the odds of VDD was significantly associated with African American race (OR 7.30, 95% CI, 1.56-34.20, P = .12) and age younger than 65 (OR 13.62 95% CI, 2.51-73.83, P = .002). Diagnoses in the "other neurologic" category were associated with decreased odds of VDD (OR 0.01, 95% CI, 0.001-0.193, P = .002). Given the high prevalence of VDD in an acute inpatient rehabilitation hospital, a routine screening and standardized supplementation protocol may improve quality of care. III.
