Off-grid communities in Senegal face significant energy challenges, necessitating robust systems for clinical outcomes measurement. A scoping review was conducted to assess the use of quasi-experimental designs in evaluating off-grid communities' energy systems, focusing on Senegal's environmental context. Quasi-experimental designs showed a moderate improvement (35%) in clinical outcomes when implemented correctly, with some variability across different community settings. Findings suggest that the use of quasi-experimental designs can be effective for measuring clinical outcomes in off-grid communities but requires tailored implementation strategies. Communities should adopt a standardised approach to ensure consistent application of quasi-experimental designs, alongside ongoing monitoring and evaluation. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
