Abstract

Background: The burden of osteoporosis in the Asia-Pacific region is not well characterized. The Medication Use Patterns, Treatment Satisfaction, and Inadequate Control of Osteoporosis Study in the Asia-Pacific Region (MUSIC OS-AP) was designed to better understand the association of gastrointestinal events with patient-reported outcomes in postmenopausal women of this region. Methods: MUSIC OS-AP is a prospective, multinational, observational cohort study of postmenopausal women ≥. 50. years of age diagnosed with osteoporosis. The study was conducted in five Asia-Pacific countries: Australia, New Zealand, Taiwan, Korea, and India. MUSIC OS-AP has three components: a physician questionnaire, a retrospective chart review, and a prospective cohort study. The physician questionnaire investigated the role of gastrointestinal events in physicians' pharmacologic management of osteoporosis. The retrospective chart review, also completed by physicians, recorded rate of osteoporosis treatment and the types of osteoporosis medications prescribed to osteoporosis patients. The prospective cohort study investigated the associations between gastrointestinal events and patient-reported outcomes among patients taking oral medications for osteoporosis as well as reasons for non-treatment in patients who remained untreated.The prospective cohort study enrolled two groups of patients: untreated, and treated with oral osteoporosis medications. Untreated patients completed only the baseline surveys, providing information on gastrointestinal event rates, quality of life, health care resource use, and reasons for non-treatment. Treated patients, who were either new to osteoporosis medication or continuing an ongoing medication course, completed surveys at baseline and 3, 6, and 12. months post-baseline. The evaluations recorded patient characteristics, gastrointestinal events, health-related and osteoporosis-specific quality of life, health care resource use, medication adherence, and satisfaction with treatment. Results: Physicians at 59 sites completed the physician questionnaire, and data for 300 patients from 26 sites were abstracted for the retrospective chart review. Enrollment and baseline data collection for the prospective cohort study were conducted between July 2013 and August 2014 for 301 untreated and 3287 treated patients, of whom 1416 were new users and 1871 were experienced users of oral osteoporosis medications. Conclusions: The results of MUSIC OS-AP will highlight the association of gastrointestinal events with patient-reported outcomes among postmenopausal women with osteoporosis and elucidate physicians' management of gastrointestinal events among this patient population in the Asia-Pacific region.
