Background: People with severe mental illnesses (SMI), including schizophrenia, are at increased risk of cardiovascular disease (CVD). Guidelines recommend regular CVD screening and in the United Kingdom, since 2004, General Practitioners are remunerated for annual reviews.
Objectives: To compare annual rates of CVD screening provision in people with and without SMI between 2000 and 2008.
Method: We identified 18,696 people with SMI and 95,512 people without SMI in the UK The Health Improvement Network (THIN) primary care database. We compared the rates of measurement of blood pressure (BP), glucose, cholesterol and body mass index (BMI).
Results: Prior to 2004, all people with SMI, were significantly less likely to receive each measurement, (including people above and below 60 years of age). In 2003; adjusted incidence rate ratios (95% CI) for screening in people with SMI under 60 years compared to people without SMI were: BMI: 0.62 (0.58-0.65); BP: 0.59 (0.56-0.62); glucose: 0.66 (0.61-0.70) and cholesterol: 0.54 (0.49-0.59). By 2007 people with SMI under 60 were equally likely receive a measurement of BMI: 1.00 (0.96-1.04), glucose: 1.00 (0.96-1.05) and cholesterol: 0.95 (0.90-1.0); the gap in screening for BP had narrowed 0.87 (0.83-0.90). However people with SMI over 60 years of age remained significantly less likely to be screened. There was little difference in screening according to social deprivation.
Conclusions: In UK primary care, people with SMI over 60 years of age remain less likely than the general population to receive annual CVD screening despite higher risk of developing CVD.
