Correlates of observing and willingness to report stigma towards HIV clients by (TB) health workers in Africa.

Abstract

Health care facilities in Kenya, Tanzania and Namibia. To study the factors associated with the observation of and willingness to report stigmatising behaviour towards persons living with the human immunodeficiency virus (HIV) among health care workers (HCWs). Mixed-effect logistic regression analyses of 9516 HCW interviews, including those of 4062 (43%) TB workers carried out as part of the Service Provision Assessments (SPAs) between 2006 and 2010. Discrimination (i.e., enacted stigma) was observed by respectively 1042 (60%), 384 (40%) and 907 (69%) TB workers in Kenya, Namibia and Tanzania, similar to the trend observed among all HCWs. Observations of discrimination were clustered at facility level in Kenya, and mapping of facility-level discrimination suggested geographic clustering. HCWs were more likely to observe discrimination in facilities without regular supportive supervision (adjusted OR [aOR] 2.33, 95%CI 1.09-4.96). No HCW characteristics were found to predict intention to report. Training in patients' rights and in confidentiality predisposed HCWs to recognise discrimination (aOR 2.51, 95%CI 1.19-5.28) and the willingness to report it (aOR 2.23, 95%CI 1.11-4.47). Exposure to training in TB infection control (IC) was associated with greater willingness to report discrimination (aOR 2.13, 95%CI 1.03-4.39). Supervision and exposure to training in patient's rights and confidentiality improved HCWs' understanding and advocacy of dignified and respectful TB-HIV care. All HCWs are equally likely to be allies, agents of change and amplifiers of an anti-stigma message, and broad engagement is required. Innovative approaches to reduce discrimination-while ensuring proper IC-should be explored.
