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

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.
