Conclusions
Four years after the end of research-related support, overall facility performance had declined as expected because of the interrupted supplies and a decline in regular supervision. However, both service availability and readiness and quality of HT/DM care were surprisingly well preserved.Sustainability of an NCD intervention in similar settings may remain achievable despite the funding instability following a trial’s end but organisational measures to prepare for the post-trial phase should be taken early on in the intervention process.
