Assessing the level of institutionalization of donor-funded anti-retroviral therapy (ART) programs in health facilities in Uganda: implications for program sustainability

Abstract

Background: In the context of declining international assistance for ART scale-up in Sub- Saharan Africa, the institutionalization of ART programs through integrating them in the organizational routines of health facilities is gaining importance as a program sustainability strategy. Objective: The aims of this study were; (i) to compare the level of institutionalization of ART programs in health facilities in Uganda and (ii) to explore reasons for variations in the degree of program institutionalization. Methods: In Phase One, we utilized Level of Institutionalization Scales developed by Goodman (1993) to measure the degree of institutionalization of ART interventions in 195 health facilities across Uganda. The 45-item questionnaire measured institutionalization based on four sub-systems (production, maintenance, supportive, managerial) theorized to make up an organization assessed against two levels of institutionalization; routines (lowest) niche saturation (highest). In Phase Two, four health facilities were purposively selected (2 with the highest and 2 with the lowest institutionalization scores) for a multiple case-study involving semi-structured interviews with ART clinic managers(n = 32), on-site observations and document review. Results: The two highest scoring health facilities had a longer HIV intervention implementation history of between 8 and 11 years. The highest scoring cases associated intervention institutionalization with sustained workforce trainings in ART management, the retention of ART-trained personnel and generating in-house ART manuals. The turnover of ART-proficient staff was identified as a barrier to intervention institutionalization in the lowest-ranked cases. Significant differences in organizational contexts were identified. The two highest-ranked health facilities were well-established, higher-tier hospitals while the lowest scoring health facilities were lower-level health facilities. Conclusions: The level of institutionalization of ART interventions appeared to be differentiated by level of care in the Ugandan health system. Interventions aimed at strengthening program institutionalization in lower-level health centers at the level of human resources for health could enhance ART scale-up sustainability.
