As part of the trial, 16 primary care units (PCUs) in Chiang Mai and Lamphun provinces will be randomly selected to receive a learning health system intervention to support quality improvement for care of HTN, T2DM and CKD. Performance will be compared between intervention PCUs and all other PCUs in the region. Participants of the realist evaluation will include clinical and other professional staff involved in the development and implementation of the LHS. This realist evaluation will use both quantitative and qualitative data, including semi-structured interviews, surveys and documents from participating sites. Quantitative and qualitative findings will be systematically integrated to test, refine and validate context-mechanism-outcomes to identify consistencies, contradictions and explanatory mechanisms as part of a final programme theory for the successful implementation of the LHS.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Ethical approval has been granted by all collaborating university Research Ethics Committees (ref: 1090, 0321, 32540).
