Knowledge and Practice on Prevention and Control of Tuberculosis Among Nurses Working in a Regional Hospital, Nepal.

Introduction: Tuberculosis (TB) is a highly prevalent communicable disease in Nepal. All health personnel who care for such patients are at high risk of developing tuberculosis. It is very necessary for all healthcare providers, especially nurses, who spend a lot of time with such patients, to have adequate knowledge and correct practice on the occupational safety measures to maintain health and prevent transmission of the disease. This study was carried out to assess the knowledge and practice of nurses in the prevention and control of TB infection.

Method: This study was a cross-sectional study conducted on nurses working in all wards and Outpatient Departments (OPDs) of Western Regional Hospital, Pokhara, Nepal. A complete enumeration of the respondents was performed, and data were collected consecutively, using a semi-structured self-administered questionnaire, from all nurses working in all the wards and OPDs of the hospital. The predictors of knowledge of TB infection prevention and control (TBIPC) were assessed using binary logistic regression.

Results: The study findings showed that a majority of nurses had an inadequate level of knowledge and poor practice of prevention and control of TB. Regarding practice, none of the nurses reported the use of an N95 mask or a respirator during care of the patients with TB and all the nurses reported that they used chemical disinfectant (virex) to clean the room and the surfaces. However, none of them reported the use of fumigation or ultraviolet irradiation for disinfection. Nurses who were 40 years and older ( = 0.001, adjusted odds ratio (A) = 5.965, = 2.083-17.457) and who were currently working in the wards with isolation rooms demonstrated higher odds for knowledge on TBIPC ( = 0.010, A = 2.686, = 1.264-5.710).

Conclusions: This study showed that a majority of nurses had an inadequate level of knowledge and implemented poor safety measures for the prevention and control of tuberculosis. This increases their risk of being infected with TB infection and cross-transmission. It is recommended that the hospital plan and conduct the necessary education/training for nurses to update their knowledge, develop the organizational structure and policies, and establish a system to support and monitor the practice of health workers on the prevention and control of TB, and maintain the health and safety of nurses caring for patients with TB.
