Table 8 Study findings on the impact of practice and specific practice-level factors on NHSHC uptake. AOR = adjusted odds ratio. OR = odds ratio. CI = confidence intervals. UR = uptake rate

From: A systematic review of factors influencing NHS health check uptake: invitation methods, patient characteristics, and the impact of interventions

StudyFindings
Artac et al., 2013 [20]Practice List Size Year 2 (all eligible patients)
> 10,000 vs. < 6000 (baseline): AOR = 6.05, 95% CI = 0.84–43.3, p < .010
Unexplained variance in models was interpreted as attributable to unmeasured practice factors
Year 1 unexplained variance = 19.4, 95% CI = 15.2–24.4%
Year 2 unexplained variance = 37.3, 95% CI = 30.6–44.6%
Attwood et al., 2016 [19]Significant variance in uptake by practice
X22 = 74.61, p < .005
Adjusting analyses for GP Practice had a substantial effect on the strength and direction of associations between socio-demographic variables (specifically gender and IMD quintile; see relevant sections above) and uptake.
Cochrane et al., 2013 [23]Practice Size
AOR = 1.03, 95% CI = 0.88–1.20, p > .100
Variance accounted for by individual practices = 12.7%, p < .001
Dalton et al., 2011 [24]Practice List Size
< 3000 vs. 3000–5999 (baseline): AOR = 2.53, 95% CI = 1.09–5.84, p = .030
≥ 6000 vs. 3000–5999 (baseline): AOR = 0.79, 95% CI = 0.33–1.88, p = .599
Variance in models accounted for by practice = 28% (VPC = 0.28)
Gidlow et al., 2014 [9]Variation in uptake by practice
X2 = 336.9, p < .001
Variation in uptake by distance to practice
X2 = 0.478, p = .924
Sallis et al., 2016 [21]Of the five practices studied, one (used as baseline in analyses) had significantly higher uptake rates than all others (all p < .010).
