Key result
Opportunistic health checks identified more patients with elevated cardiovascular risk (≥10%) than standard invitation letters (22.2% vs 17.0%; relative increment 28%, P<0.001).
Why the study?
Do opportunistic health checks identify a higher proportion of patients with elevated cardiovascular risk compared to postal invitations in a general practice population?

Do opportunistic health checks identify a higher proportion of patients with elevated cardiovascular risk compared to postal invitations in a general practice population?
Opportunistic health checks identify significantly more individuals with elevated cardiovascular risk compared to standard postal invitations, particularly in deprived populations.
Opportunistic checks were associated with higher CVD risk detection in primary care; hypothesis-generating and requires RCTs before practice change.
Background: A population-based programme of health checks has been established in England. Participants receive postal invitations through a population-based call-recall system but health check providers may also offer health checks opportunistically. We compared cardiovascular risk scores for 'invited' and 'opportunistic' health checks. Methods: Cohort study of all health checks completed at 18 general practices from July 2013 to June 2015. For each general practice, cardiovascular (CVD) risk scores were compared by source of check and pooled using meta-analysis. Effect estimates were compared by gender, age-group, ethnicity and fifths of deprivation. Results: There were 6184 health checks recorded (2280 invited and 3904 opportunistic) with CVD risk scores recorded for 5359 (87%) participants. There were 17.0% of invited checks and 22.2% of opportunistic health checks with CVD risk score ≥10%; a relative increment of 28% (95% confidence interval: 14-44%, P < 0.001). In the most deprived quintile, 15.3% of invited checks and 22.4% of opportunistic checks were associated with elevated CVD risk (adjusted odds ratio: 1.94, 1.37-2.74, P < 0.001). Conclusions: Respondents at health checks performed opportunistically are at higher risk of cardiovascular disease than those participating in response to a standard invitation letter, potentially reducing the effect of uptake inequalities.

Gulliford et al. (2017) conducted a cohort in Cardiovascular risk (n=6,184). Opportunistic health checks vs. Invited health checks was evaluated on CVD risk score ≥10% (Relative increment 28%, 95% CI 14-44, p=<0.001). Opportunistic health checks identified more patients with elevated cardiovascular risk (≥10%) than standard invitation letters (22.2% vs 17.0%; relative increment 28%, P<0.001).
