Abstract

Summary: While adherence to osteoporosis treatment is low, patients’ preference for osteoporosis treatment is unknown in Chinese patients. Chinese patients are willing to receive treatments with higher clinical efficacy and lower out-of-pocket cost. In addition, annual intravenous infusion and 6-month subcutaneous injection are preferred over weekly oral tablets. Purpose: This study was performed to elicit Chinese patients’ preferences for osteoporosis medication treatment and to investigate the heterogeneities of the preferences in subgroups. Methods: A discrete choice experiment comprising 15 choice sets with 4 important attributes was conducted in a Chinese population at risk of osteoporotic fracture. The four attributes were treatment efficacy in reducing the risk of fracture, out-of-pocket cost per year, adverse effects of treatment, and mode of administration. The patients were asked to choose between two hypothetical treatments; they could also choose no treatment. Mixed logit models were used, and any observed heterogeneity in the patients’ preferences was further assessed in subgroup analyses. Results: In total, 267 patients were analysed. On average, the patients preferred to receive treatment rather than no treatment. The patients preferred treatment with higher efficacy in preventing fracture and lower out-of-pocket cost. The least preferred adverse effect of medication was gastrointestinal disorders, followed by flu-like symptoms and finally skin reactions. The most preferred mode of administration was annual intravenous infusion, followed by 6-month subcutaneous injection, a weekly oral tablet, and daily nasal spray; daily oral tablets ranked as the least preferred mode of administration. The differences in the patients’ preferences among all attributes were statistically significant (p < 0.05). Patients’ age was found to contribute to the observed preference heterogeneity in most of the included attributes. Conclusions: This study revealed Chinese patients’ preferences for osteoporosis treatments. Annual intravenous infusion and 6-month subcutaneous injection were significantly preferred over weekly oral tablets in this Chinese population.
