Abstract
Background
Many women with osteoporosis do not initiate osteoporosis treatment.
Objective
To examine patients’ reasons for not initiating osteoporosis treatment among women with osteoporosis.
Methods
Survey recipients were identified from a national US claims database and included women ≥55 years with an osteoporosis diagnosis from January 1, 2010 to March 31, 2012 as defined by: 1) osteoporosis diagnosis coupled with bone mineral density test within 183 days of diagnosis and/or 2) osteoporosis-related fracture. Eligibility required no claims for osteoporosis medication 1) at least 12 months and up to 5 years prior to osteoporosis diagnosis and 2) at least 6 months after osteoporosis diagnosis. Continuous enrollment for 18 months (6 months pre-osteoporosis and 12 months post-osteoporosis diagnosis) was also required. A total of 2,000 patients with the most recent osteoporosis diagnosis were mailed a survey. Respondents reporting that they did not initiate physician-recommended osteoporosis medication, after either their physician told them they had osteoporosis or they experienced a fracture since age 45 years, were asked for reasons why they did not initiate treatment.
Results
There were 430 patients who returned a complete survey; mean age was 61% and 21.6% had a fracture. A total of 197 (45.8%) patients reported their physician diagnosed osteoporosis and 117 (59.3%) of those were recommended osteoporosis medication; 44 of the 117 patients (37.6%) did not initiate recommended osteoporosis medication by the time of survey. The primary reasons for not initiating osteoporosis medication were concern over side effects (77.3%), medication costs (34.1%), and pre-existing gastrointestinal concerns (25.0%).
Conclusion
Among respondents, 41% of patients whose physician diagnosed osteoporosis were not recommended osteoporosis treatment and 38% of patients who were recommended osteoporosis treatment did not initiate treatment within approximately 2 years of diagnosis. Concerns with side effects of osteoporosis treatment, medication costs, and pre-existing gastrointestinal concerns were the most common reasons for not initiating recommended treatment.
