Effectiveness of pharmaceutical care on treatment outcomes for patients with first-time pulmonary tuberculosis in China.

Abstract

In this study, the effectiveness of pharmaceutical care on treatment outcomes for patients with first-time pulmonary tuberculosis in China was assessed. In this study, patients were randomized either to the usual care (UC) group (n=72) where patients received routine medical and nursing care or to the pharmaceutical care (PC) group (n=59) where patients were simultaneously provided with pharmaceutical care. The primary objectives were to evaluate whether treatment outcomes and patient adherence improved more in the PC group than in the UC group. In addition, in PC group, outcomes included the number of patient-reported pharmaceutical care issues and pharmacists' interventions. As compared to the UC group, treatment success rate was improved in the PC group, but the difference was not statistically significant (71% vs 54%; P=0.137). However, as compared to the UC group, the number of patients who attended all of the scheduled visits was higher in the PC group; the difference was statistically significant (81% vs 60%, P=0.018). Furthermore, the number of patients who had positive test results for all of the isoniazid tests was higher in the PC group than in the UC group; the difference was also statistically significant (80% vs 50%, P=0.002). The consumed medication rate was improved in the PC group, but no significant difference was found between the two groups. The patient-reported pharmaceutical care issues mainly included dermatological, gastrointestinal, hepatic, metabolic, sensory, central nervous system and haematological problems. On the basis of clinical examination, laboratory parameters and drug information database, the pharmacists addressed most of these pharmaceutical care issues. Pharmaceutical care might improve patient adherence for patients with first-time pulmonary tuberculosis in China, and further, rigorously controlled trials are required.
