Evaluating the clinical effectiveness of the NHS Health Check programme: a prospective analysis in the Genetics and Vascular Health Check (GENVASC) study

OBJECTIVE: The aim of the study was to assess the clinical effectiveness of the national cardiovascular disease (CVD) prevention programme—National Health Service Health Check (NHSHC) in reduction of CVD risk. DESIGN: Prospective cohort study. SETTING: 147 primary care practices in Leicestershire and Northamptonshire in England, UK. PARTICIPANTS: 27 888 individuals undergoing NHSHC with a minimum of 18 months of follow-up data. OUTCOME MEASURES: The primary outcomes were NHSHC attributed detection of CVD risk factors, prescription of medications, changes in values of individual risk factors and frequency of follow-up. RESULTS: At recruitment, 18% of participants had high CVD risk (10%–20% 10-year risk) and 4% very high CVD risk (>20% 10-year risk). New diagnoses or hypertension (HTN) was made in 2.3% participants, hypercholesterolaemia in 0.25% and diabetes mellitus in 0.9%. New prescription of stains and antihypertensive medications was observed in 5.4% and 5.4% of participants, respectively. Total cholesterol was decreased on average by 0.38 mmol/L (95% CI −0.34 to −0.41) and 1.71 mmol/L (−1.48 to −1.94) in patients with initial cholesterol >5 mmol/L and >7.5 mmol/L, respectively. Systolic blood pressure was decreased on average by 2.9 mm Hg (−2.3 to −3.7), 15.7 mm Hg (−14.1 to −17.5) and 33.4 mm Hg (−29.4 to −37.7), in patients with grade 1, 2 and 3 HTN, respectively. About one out of three patients with increased CVD risk had no record of follow-up or treatment. CONCLUSIONS: Majority of patients identified with increased CVD risk through the NHSHC were followed up and received effective clinical interventions. However, one-third of high CVD risk patients had no follow-up and therefore did not receive any treatment. Our study highlights areas of focus which could improve the effectiveness of the programme.
