Methodological Evaluation of Off-Grid Communities Systems in Ethiopia Using Difference-in-Differences for Clinical Outcome Measurement

The digital divide persists in off-grid communities across Africa, where access to reliable electricity is limited, impacting healthcare outcomes. We employed a DiD approach to assess changes in health indicators before and after the implementation of off-grid energy solutions, comparing pre-intervention with post-intervention periods within treatment and control groups. An analysis revealed an increase in vaccination coverage by 25% among children under five years old in treated communities compared to controls, indicating a significant positive impact on health metrics. The DiD model demonstrated the potential of off-grid systems to improve healthcare delivery in resource-limited settings. Further research should explore long-term impacts and scalability of these interventions.
