Abstract


A cross sectional study will be undertaken whereby risk assessments will be undertaken in PHCs in the Durban South Region of the eThekwini Municipality. During this period, medical interviews and examinations will be conducted amongst health care workers. The collected data will then be cleaned and collated and entered onto an Excel Spreadsheet. This data will then be analysed using Stata Version 10.

The outcome to be investigated will be TB in health care workers which will be a binary variable. Initially these factors will be analysed using univariate and bivariate analysis. Multivariate analysis, using binary logistic models, will used to describe the relationship between the TB outcome and the variables in question. These exposure variables will be categorised as being either work related or individual related i.e.:

Work related factors include the prevalence of TB in the workplace; times exposed to suspected TB patients and possible environmental factors like air changes per hour.

Individual factors to be considered will include number of years worked in the PHC, immunosuppressive disorders and history of TB contacts.

Possible confounding factors like exposure to other working environments that may predispose an individual to TB will also be considered.
