Audit on follow-up of patients with primary Osteoporosis

Abstract

Aim: To document the frequency of Dual-energy X- ray absorptiometry (DEXA) scanning and Rheumatology clinic follow-up visits of patients with primary osteoporosis, and compare these with recommended guidelines. Method: Medical notes of all primary osteoporotic patients attending a hospital Rheumatology clinic were reviewed over a period of four months. Data was collected on age, gender, frequency of follow up visits, frequency of DEXA scanning, osteoporosis treatment, any changes in such treatment during the last visit, and comparison of the last two DEXA scan results. Frequency of follow up DEXA scans was compared to Group Health Osteoporosis Screening Diagnosis and Treatment guidelines.1 Results: Eighty-two patients were included, 6 males (7.3%) and 76 females (92.7%). The age range was 35-87 years (mean age was 68.6 years). In total, 42.7% of all the patients were on combined calcium and vitamin D, with added Bisphosphonates, Strontium ranelate, or Denosumab. During their last clinic visit, 61% showed improvement in T score since their previous result, and 64.6% of patients had no change in treatment. In this audit, 29.3% were being followed up on a 13 monthly basis, and 72% had annual bone mineral density scans or more frequently Conclusion: According to the guidelines, none of the patients included in this audit should have had a repeat DEXA scan within less than two years. Patients attending the clinic have too frequent DEXA scans and therefore, too frequent follow up appointments.
