Video-Observed Therapy, pulmonary tuberculosis



Introduction: Pulmonary tuberculosis (TB) is still one of the major health problems in Thailand.  Knowledge and self-care behavior among these TB patients, especially in new cases, are important to help patients recover from the disease. And these can effectively prevent the spread of disease.  

Research objectives: This quasi-experimental study aimed to evaluate an effect of the information, motivation, and behavioral skills model with video-observed therapy (VOT) program in new patients with pulmonary TB.  Sixty-six patients were randomly assigned into an experimental group (n=33) and a comparison group (n = 33).) Inclusion criteria were patients: (a) aged 20 to 60 years old with Acid-Fast Bacilli (AFB) positive result; and (b) who registered in a TB clinic located in Nonthaburi province. The experimental group received a routine care combined with 8-week intervention educational session, including infection control, drug adherence, and side-effect management. Also, they were provided with VOT and weekly sending  info graphic message. The comparison group received only a routine care.  Data were collected using  a set of self-administered questionnaires such as individual knowledge of TB, self-care behavior, and sputum test result.  Data were analyzed using Chi-square test, Repeated Measure ANOVA, and independent t-test.

Results:  Findings revealed that among the participants in the experimental group, TB knowledge, and self-care behaviour were found to be significantly improved between baseline and follow-up (8- and 12-week) (p < .05). At follow-up, between-group significant differences were also found on TB knowledge, and self-care behaviour (p < .05).

At follow-up, the sputum test among the participants in the experimental group at   8- and 12-week were more significantly improved than those at baseline (p<.05). However, there was not significantly different on testing result between groups at the end of the study.

Conclusion: At follow-up, Information, motivation, and behavioral skills model with VOT program mutually increased more TB knowledge, and self-care behaviour of the experimental group than at baseline. When conducted between-group analyses with follow-up data, we found that the experimental group showed more significant improvements on TB knowledge, and self-care behaviour than the comparison group. At follow-up the experimental group also reported the better sputum test results than at baseline. Nonetheless, the sputum test results of the experimental group were not significantly different from the comparison group.

Implications for practice: Instead of using DOT, healthcare workers should use VOT in pulmonary TB patients during the COVID-19 outbreak. It can prevent the spread of COVID-19 and reduce the medical care cost of TB.
