Background: The Integrated Primary Care (IPC) rotation is undertaken over six weeks by final year medical students at the University of Witwatersrand. Students are placed in either rural or urban primary health care centres based in Gauteng or the North West Province. As part of the IPC rotation, students undertake short quality improvement (QI) projects. The purpose of this study is to evaluate the impact of the QI projects undertaken over the period stretching from 2006 to 2010. Methods: An observational study of QI reports done by students. Project reports assessed and compared to site marks, indicators of learning assessed and individual and group marks compared.Results: Of 274 projects undertaken, 223 (81.4%) were available for evaluation. Geographical placements and QI themes were categorised. Management issues were most frequently identified as being problematic followed by chronic illnesses. Understanding and applying the principles of QI was partially achieved and gaps were identified for future projects. The most common intervention was training of personnel and design and distribution of posters or pamphlets.Conclusions: Most QI projects were well thought out and relevant to the chosen setting. In the majority of cases, a great deal of effort and creativity went into the process and skills other than clinical skills were employed such as writing, presentation of data in graphs and tables. Integration of theory and practice was achieved only partially.
