Compliance of osteoporotic patients with different treatment regimens
Abstract
BACKGROUND: The treatment of osteoporosis among postmenopausal women represents a major public health challenge since long-term therapy is needed to prevent fractures and chronic disability.
OBJECTIVES: To assess compliance with osteoporosis drug therapy among Israeli postmenopausal women treated with either a bisphosphonate (alendronate) or a selective estrogen receptor modulator (raloxifene); to identify factors affecting compliance among these patients; and to compare adherence to the treatment in these two groups.
METHODS: Our study included 178 consecutive patients aged 67.41 +/- 8.52 years who were treated for osteoporosis with alendronate or raloxifene in the Metabolic Bone Diseases Unit. All the patients received supplementation with calcium carbonate 1,500 mg and 600 IU vitamin D daily. Compliance was assessed at a clinic visit 6 months after starting therapy.
RESULTS: The dropout rate was 23% (41 patients): 20 patients (31%) in the raloxifene group and 21 (18%) in the alendronate group (P = 0.0041). The main reasons for dropout were side effects and/or noncompliance, 16 and 24 patients (39% and 58.53%) respectively. The most frequent side effect was abdominal pain in 9 patients (42.8%) who discontinued alendronate use. The reasons for non-compliance were a fear of side effects and high drug price in 6 (30%) and 4 (20%) patients respectively in the raloxifene group, and inconvenience caused by medication use in 3 patients (14.3%) in the alendronate group.

How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 178 participants or records.
