Scientific titleHigh blood pressure control and lipid lowering in patients at high cardiovascular risk: a cluster randomised factorial comparison of educational and protocol-based interventions to help primary care teams improve control of patients with poor risk factor control
Study acronymHiLo
Study objectivesThis is a 2 x 2 factorial design complex health services intervention research trial which examines the influence of none, either or both of two interventions designed to help primary care clinicians improve the blood pressure and cholesterol control of patients at high risk of cardiovascular events over 12 months. One intervention explores expertise sharing whilst the other explores protocol adherence by clinicians.
