Retrospective analysis of the use of osteoporosis medication at the presentation of non-vertebral fragility fractures in a predominantly Hispanic population.

Abstract

Background: Despite the high incidence of osteoporosis, many patients at risk of fragility fractures may not initiate treatment due to concerns about side effects, cost or under-diagnosis, such as the case of vertebral fractures. We aimed to identify whether the patient population with non-vertebral fragility fractures where already receiving prophylactic treatment for osteoporosis at presentation within a regional hospital in the southernmost region of the United States. This region is characterized by a high number of patients from Hispanic/Latino heritage (80%) and reduced access to healthcare services. Methods: We conducted a three-year, retrospective cohort study of patients presenting with low impact fractures of the humerus or the shoulder griddle, lower end of radius or ulna and forearm, hip fractures (femoral neck, intertrochanteric/ subtrochanteric), and ankle fractures. Male and female subjects of 50 years or older were included. Demographic data and information on medications reported at fracture presentation were extracted from electronic medical records. Results: We found that 42% of the patients were taking at least one medication to prevent osteoporosis. The predominant combination was vitamin D plus calcium and bisphosphonates. If patients taking only vitamin D plus calcium are excluded, 16.7% of the sample took osteoporosis medications at the fragility fracture presentation. The likelihood of taking osteoporosis medication was increased by age and type of health insurance (Medicare/private insurance), and concomitant diagnosis of impaired gait and mobility. The percentage of the patients taking prophylactic medications for osteoporosis at the time of a fragility fracture was comparable to reported national standards and associated with increased age and health insurance coverage. Conclusion: In a predominantly Hispanic/Latino patient population living in a medically underserved region, there is substantial recognition and prevention strategies for osteoporosis.
