Zusammenfassung:Background Hypertension is a serious public health problem in Singapore and is associated with significant morbidity and mortality from cardiovascular disease (CVD) with considerable implications for health-care resources. The goal of the trial is to compare a multicomponent intervention (MCI) to usual care to evaluate the effectiveness and cost-effectiveness of the MCI for lowering blood pressure (BP) among adults with uncontrolled hypertension in Singapore primary-care clinics. Methods/design The study is a cluster randomized trial in eight polyclinics in Singapore: four deliver a structured MCI and four deliver usual care. The components of the MCI are: (1) an algorithm-driven antihypertensive treatment for all hypertensive individuals using single-pill combination (SPC) and lipid-lowering medication for high-risk hypertensive individuals, (2) a motivational conversation for high-risk hypertensive individuals, (3) telephone-based follow-ups of all hypertensive individuals by polyclinic nurses, and (4) discounts on SPC antihypertensive medications. The trial will be conducted with 1000 individuals aged [greater than or equai to] 40 years with uncontrolled hypertension (systolic BP [greater than or equai to] 140 mmHg or diastolic BP [greater than or equai to] 90 mmHg, based on the mean of the last two of three measurements) in eight polyclinics in Singapore. The primary outcome is change in systolic BP from baseline to follow-up at 24 months post-randomization. The incremental cost of MCI per CVD disability adjusted life years (DALY) averted and quality adjusted life years (QALY) saved will be computed. Discussion The demonstration of an effective and cost-effective hypertension control program that is implementable in busy polyclinics would provide compelling evidence for upscaling the program across all primary-care centers in Singapore, and possibly other regional countries with a similar health-care structure.
