RESUMEN
BACKGROUND: Access to safe, high-quality surgical care in sub-Saharan Africa is a critical gap. Interventions to improve surgical quality have been developed, but research on their implementation is still at a nascent stage. We retrospectively applied the Exploration, Preparation, Implementation, Sustainment framework to characterize the implementation of Safe Surgery 2020, a multicomponent intervention to improve surgical quality. METHODS: We used a longitudinal, qualitative research design to examine Safe Surgery 2020 in 10 health facilities in Tanzania's Lake Zone. We used documentation analysis with confirmatory key informant interviews (n = 6) to describe the exploration and preparation phases. We conducted interviews with health facility leaders and surgical team members at 1, 6, and 12 months (n = 101) post initiation to characterize the implementation phase. Data were analyzed using the constant comparison method. RESULTS: In the exploration phase, research, expert consultation, and scoping activities revealed the need for a multicomponent intervention to improve surgical quality. In the preparation phase, onsite visits identified priorities and barriers to implementation to adapt the intervention components and curriculum. In the active implementation phase, 4 themes related to the inner organizational context-vision for safe surgery, existing surgical practices, leadership support, and resilience-and 3 themes related to the intervention-innovation-value fit, holistic approach, and buy-in-facilitated or hindered implementation. Interviewees perceived improvements in teamwork and communication and intra- and inter-facility learning, and their need to deliver safe surgery evolved during the implementation period. CONCLUSIONS: Examining implementation through the exploration, preparation, implementation, and sustainment phases offers insights into the implementation of interventions to improve surgical quality and promote sustainability.
