Hong Kong has now paired more than 200,000 citizens with a family doctor through the Chronic Disease Co-Care Scheme, wrapped multidisciplinary support around them through the District Health Centres, and in March 2026 made the scheme permanent inside a new Primary Healthcare Co-care Network that aims to reach 700,000 people. It is the largest change to Hong Kong primary care in a generation. But we still do not know whether the people inside it receive measurably better care than comparable people outside it, because no study has ever compared the two. The author proposes a prospective cohort study: to recruit adults newly found to have hypertension, diabetes, prediabetes or dyslipidaemia — one group managed within Co-Care, one group managed in usual care outside it — assess both at baseline and at twelve months and compare the quality of care they receive and the control they achieve.
