Table 3 Processes for ensuring rigour in case-study analysis adapted from Gilson et al. (2012) [30]
PRINCIPLE | |
|---|---|
Prolonged engagement | Multiple on-site visits were made to the case-study facilities. Investigators engaged in informal discussions with clinicians and HIV clinic managers as well as conducting formal, face-to-face interviews with multiple informants per health facility. |
Use of theory | This study draws upon the analytical framework by Shediac-Rizkallah & Bone (1998). |
Case selection | Sixteen health facilities which run a stand-alone HIV clinic were purposefully selected from a nationally-representative sample of 195 health facilities across Uganda participated in the pilot national ART roll-out phase. |
Sampling | We aimed to have a sample that had appropriate representation of health facility demographics in Uganda with respect to a) setting(rural/urban), b) ownership-type(public, for-profit, not-for-profit) c) Level of care(tertiary, secondary, primary). |
Multiple methods | Multiple methods were used including face-to-face interviews, a structured questionnaire and informal engagements with clinicians and the head of the ART Clinic |
Triangulation | Case descriptions were constructed based on triangulation across multiple data sources (Questionnaire data and, interviewee data). |
Peer debriefing and support | Data analysis involved a team-based process involving at least three authors. |
Respondent validation | A data validation workshop was conducted with involving the head of the HIV clinic in 14 of the participating health facilities. |
