An exploration of health workers risks of contracting tuberculosis in the workplace: a qualitative study

To explore the perceptions of health workers on the risks of contracting tuberculosis at Namwala District Hospital. Tuberculosis literature indicates that health workers are at risk of contracting tuberculosis while conducting their daily duties in the workplace. This is mainly attributed to low tuberculosis awareness. It is with this empirical evidence that this study was conducted to further explore health workers risky behavior, attitude and practices that expose them to tuberculosis infection when on duty and eventually generate effective health promotion and public health interventions.

Semi-structured interviews lasting between 35 to 45 min were conducted to all the participants. A purposive sampling technique was used to recruit ten participants for this study. All the ten interviews were audio recorded in order to enhance consistency during data analysis process. Interview materials were transcribed verbatim, coded and themes generated to form thematic networks. Data analysis was conducted using thematic analysis strategy.

Four themes were identified; 1. Health workers personal safety: participants reported wearing uniforms and gloves but they were not putting-on face masks hence, exposing themselves to tuberculosis infection. 2. Tuberculosis infection prevention practices: hand washing was described by many participants as a universal method of protecting health staff from the risks of contracting tuberculosis at the hospital however, few health workers frequently washed their hands after attending to tuberculosis patients. 3. Health workers working environment: the working environment at the hospital was not conducive for both health workers and patients due to poor ventilation, unhygienic conditions, overcrowding and the lack of an isolation ward. 4. Health promotion: awareness on tuberculosis was reported to be low with no refresher training being conducted for health workers at the hospital.

The risks of contracting tuberculosis by health workers at Namwala District Hospital did exist hence, a need of advocating for tuberculosis awareness for health workers through appropriate health promotion interventions. Health policy should focus on continuous health promotion activities on prevention and control of tuberculosis in health facilities and communities.
