District hospitals in Rwanda face challenges in implementing new healthcare systems efficiently. A systematic review was conducted to identify and analyse randomized field trial methodologies used in assessing the adoption rates of healthcare innovations in Rwandan district hospitals. Studies were included if they utilised a random allocation design and reported data on adoption rates. In one study, a logistic regression model estimated that 45% (95% CI: 38-52%) of district hospitals adopted a new infection prevention protocol within the first year. Randomized field trials provided robust evidence for measuring adoption rates in Rwandan district hospitals, although variability existed across studies. Further research should explore longitudinal data to assess long-term sustainability and effectiveness of implemented healthcare innovations. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
