For more than a decade now Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH (former GTZ) has supported HIV/AIDS workplace programmes via public-private partnerships. One major objective has been to prevent new HIV infections. In order to close relevant evidence gaps, GIZ supported accompanying research projects in Namibia and Ghana.

Namibia: Evaluation of a HIV workplace programme
In the first quarter of 2011 in close cooperation with the University of Namibia (UNAM) more than 1.300 staff in the public and private sector working in the regions Windhoek, Hardcap, Erongo, Oshana and Caprivi were asked via KAPB-survey about their knowledge, attitudes, practices and behaviour with regard to HIV/AIDS. The cross sectional analysis shows, that staff from companies with an established HI/AIDS workplace programme are more likely to get tested for HIV as compared to  staff from companies with more recent workplace programmes. No significant differences could be observed regarding knowledge, attitudes and behaviour with regard to HIV. The data collection provides important baseline information for future evaluations.

Ghana: Cost-benefit analysis
The results from Ghana prove the hypothesis, that investments in expanded HIV workplace programmes pay off from the perspective of the companies! In the long term the interventions increase the productivity of the staff, which again results in higher productivity for the companies.
