OBJECTIVE: Findings from the Viborg Vascular (VIVA) trial show a mortality benefit of multi-faceted vascular screening which was mainly ascribed to the initiation of prophylactic medication. However, the pharmacological preventive potential, which exists when individuals have a positive screening test result and do not already use statins and anti-platelet agents, has not been analysed. The aim of this study was to investigate factors associated with a pharmacological preventive potential of statins and anti-platelet agents among attenders vascular screening for abdominal aortic aneurysm (AAA) and peripheral arterial disease (PAD).

METHODS: This cross-sectional study used data from the VIVA trial screening arm including 25 074 men aged 64-75 years recruited between October 2008 and January 2011. Explanatory variables comprised socio-demographic- and socio-economic characteristics, comorbidities, medication use, and travel distance derived from nationwide registries. Outcomes included a positive screening test result, a pharmacological preventive potential, and attendance. Associations between the explanatory variables and the outcomes were investigated using the chi-square test and multivariate logistic regression.

RESULTS: The factors most likely to be associated with a pharmacological preventive potential for positive AAA screening comprised age >70 years (odds ratio (OR) 1.23, 95% confidence interval 1.00-1.51), existing chronic obstructive pulmonary disease (COPD) (OR 2.22, 95% CI 1.38-3.57), and use of anti-hypertensives (OR 1.37, 95% CI 1.09-1.71). For positive PAD screening age >70 years (OR 1.41, 95% CI 1.25-1.60), living alone (OR 1.34, 95% CI 1.14-1.56), low income, COPD (OR 2.13, 95% CI 159-283), use of anti-hypertensives (OR 1.14, 95% CI 1.00-1.29) or anti-diabetics (OR 1.12, 95% CI 1.01-1.28), and short travel distance were associated with a pharmacological preventive potential. For combined vascular screening, age >70 years, living alone, low income, COPD, and use of anti-hypertensives were associated with a pharmacological preventive potential. Among these subgroups, lower attendance was associated with age >70 years, living alone, low income, COPD, and use of anti-diabetics.

CONCLUSION: Future vascular screening programmes might benefit from tailoring information to subgroups who are more likely to benefit from screening but less likely to accept an offer.
