Health-related quality of life among patients with postmenopausal osteoporosis treated with weekly and monthly bisphosphonates.

OBJECTIVE

The present study was designed to assess the effect of monthly ibandronate on health-related quality of life (HR-QoL) in patients with postmenopausal osteoporosis previously treated with weekly bisphosphonates.

METHODS

HR-QoL was assessed by Euroqol (EQ-5D) and Osteoporosis Targeted Quality of Life (OPTQoL) questionnaires.

RESULTS

The EQ-5D questionnaire showed significant improvement associated with ibandronate treatment, occurring in mobility (p < 0.01), usual activity (p < 0.01), pain/discomfort (p < 0.05), and anxiety/depression (p < 0.05). In addition, ibandronate treatment considerably improved patients' perceived health on a visual analog scale (p < 0.001). For the OPTQoL questionnaire, patients reported less physical difficulty (p < 0.001), fewer adaptations in their lives (p < 0.001), and less fear (p < 0.001) with ibandronate than with weekly bisphosphonates.

CONCLUSION

The study demonstrated that patients who were transferred from weekly bisphosphonates to a monthly ibandronate experienced improved HR-QoL.
