323. Fragility Fracture Risk in HIV: Awareness Among Primary Care Providers

Abstract Background Recommendations on screening HIV-infected (+) patients for bone disease exist. We sought to characterize awareness of and adherence to HIV-specific recommendations and assess risk factors for fracture in this population. Methods Primary care provider (PCP) and ID specialist awareness of screening recommendations was assessed using an anonymous electronic survey. We conducted interviews of 45 HIV+ patients and chart review. We calculated risk using the fracture risk assessment tool (FRAX). Email notifications were sent if an indication dual-energy x-ray absorptiometry (DXA) scans was identified. Chart review was repeated 12 months later to assess response. Statistical methods included chi-square and Fisher’s exact test for categorical data, and t-tests or Wilcoxon rank-sum tests for continuous data. A multivariate logistic regression examined the relationship between adult fragility fractures and covariates. Results No immunologic or virologic factors or exposure to specific antiretroviral therapies (ART) were associated with FFX (Table 1). FRAX score (hip, major osteoporotic fracture) successfully predicted FFX history (P = 0.002, P = 0.001, respectively). Overall, 35 (78%) patients qualified for DXA; 23 (66%) were men, only 8 (23%) had a previous DXA. Following provider notification, an additional 5 patients had DXA ordered. DXA was recommended for all patients with FFX, compared with 68% without a fracture (P = 0.02). In logistic regression modeling, increasing age, male sex, and months of ART therapy were associated with FFX (Table 2). Twenty-seven providers responded to the pre-intervention survey, of whom only 35% were aware of screening recommendations for HIV+ patients. Of the 18 providers who responded post-intervention, 63% were aware of these recommendations (Table 3). Conclusion A brief educational intervention resulted in increased awareness of HIV-specific screening recommendations, but this translated into adherence to a lesser extent. HIV+ men were more likely to have a history of fragility fracture compared with females. No specific ART or immunologic marker predicted fracture risk or history. Fostering a greater understanding of unique characteristics and risks in this population is crucial to ensure appropriate preventive care. Disclosures All authors: No reported disclosures.
