Exploring the efficacy of a case management model using DOTS in the adherence of patients with pulmonary tuberculosis

Abstract

Aim: To explore the efficacy of hospitals using case management with Directly Observed Treatment - Short course (DOTS) to monitor the adherence of patients with pulmonary tuberculosis in Taiwan.

Background: Non-adherence to anti-tuberculosis chemotherapy is the major problem in treating patients with tuberculosis. Community-based case management coupled with DOTS has been applied to patients with tuberculosis and has resulted in good results in some countries. Taiwan has a high incidence of tuberculosis, and although it has implemented DOTS, the expected increased efficacy has not yet been realized.

Design and methods: The study used a quasi-experimental design. Using age and gender as matching factors, 96 subjects were randomly assigned to one of three groups in 2002-2003. Experimental group I was to receive DOTS case management comprising in-hospital education, direct daily observation in the first two months and one home visit per week. Experimental group II received traditional case management comprising in-hospital education and one home visit per month. The control group did not receive any intervention.

Results: The adherence, the rate of completion, the treatment success, sputum conversion and chest X-ray improvement of experimental group I were significantly improved compared with experimental group II and the control group. The completion rate in experimental group I was higher than the general rate for Taiwan during the past six years and the treatment success rate met the standards of the World Health Organization.

Conclusion: Hospitals using case management with DOTS can improve the adherence of tuberculosis patients and the control of tuberculosis-epidemic situations. Relevance to clinical practice. In a rapidly changing healthcare environment, clinical nurses can make a significant contribution to healthcare delivery for tuberculosis patients. This study has provided further insight into the implementation of hospital-to-community level case management using DOTS by nurses.
