Improved appropriateness of anti-tuberculosis prescription by the expert prescription review program in Taiwan

Abstract

Background: A nationwide program initiated by Taiwan CDC was conducted by the Taiwan Society of Tuberculosis and Lung Disease to improve the appropriateness of anti-TB prescriptions in Taiwan. Methods: All anti-TB prescriptions from 12 hospitals across Taiwan were reviewed by experienced pulmonologists, according to the 2011 Taiwan TB treatment guidelines, between May and October 2013. The investigation period was divided into three stages: May to June, July to August, and September to October. The concordance rates between anti-TB prescriptions and the guidelines were compared among the three stages and between medical centers and regional hospitals. Results: A total of 2574 new anti-TB prescriptions were reviewed. The appropriateness of anti-TB prescriptions was 82.0%. The most dominant error was inappropriate dosage of anti-TB medications. The appropriateness improved significantly with prescription review, and the concordance rates were 78.7%, 80.6%, and 87.6% in stages 1, 2, and 3, respectively (P < 0.001). The inappropriateness of medication dosage also improved significantly, with the rates of inappropriate dosage dropping from 10.2% in stage 1–5.4% in stage 3 (Odds ratio 0.491, P < 0.001). The appropriateness rates showed no significant difference between regional hospitals and medical centers (82.5% vs. 81.3%, Odds ratio 0.915, P = 0.393), but the improvement of prescription appropriateness was significant in regional hospitals but not in medical centers. Conclusion: Prescription review by TB experts is an effective approach to improve the appropriateness of anti-TB prescriptions.
