Summary
The aim of this study was to determine whether feedback by pharmacists to prescribers of patients eligible for glucocorticoid-induced osteoporosis prophylaxis would stimulate the prescribing of osteoporosis prophylaxis. The intervention did not significantly increase the prescribing of bisphosphonates in the total study population, but a significant increase was seen in men and in the elderly. However, the proportion of bisphosphonate-treated patients remained low.
Introduction
The aim of this study was to determine whether feedback by pharmacists to prescribers of patients eligible for glucocorticoid-induced osteoporosis prophylaxis (GIOP) would stimulate the implementation of the Dutch GIOP guideline.
Methods
This randomised controlled trial included 695 patients who were dispensed ≥675 mg prednisone equivalents without a concomitant bisphosphonate prescription within 6 months before baseline. Pharmacists were asked to contact the physicians of GIOP-eligible patients in the intervention group to suggest osteoporosis prophylaxis. The primary endpoint was a bisphosphonate prescription. Secondary endpoints were a prescription of calcium supplements, vitamin D or any prophylactic osteoporosis drug (bisphosphonate, calcium supplements, vitamin D).
Results
The group assigned to the intervention was slightly younger than the control group (68.7 ± 15.4 vs. 65.9 ± 16.9 years, p = 0.02) and used hydrocortisone more often (7.0 % vs. 3.1 %, p = 0.02). Within 6 months, the intervention did not significantly increase the prescribing of bisphosphonates (11.4 % after intervention vs. 8.0 % for controls; hazard ratio [HR] 1.47, 95 % confidence interval [CI] 0.91–2.39). However, subgroup analyses showed a significant increase for the primary endpoint in men (12.8 % vs. 5.1 %, HR 2.53, 95 % CI 1.11–5.74) and patients ≥70 years (13.4 % vs. 4.9 %, HR 2.88, 95 % CI 1.33–6.23). The prescribing of calcium and vitamin D was not significantly altered.
Conclusion
This study showed that active identification of patients eligible for GIOP by pharmacists did not significantly increase the prescribing of bisphosphonates in the total study population, but there was an increase in men and the elderly. However, the proportion of GIOP-treated patients remained low.
