Comparison of self-report influenza vaccination coverage with data from a population based computerized vaccination registry and factors associated with discordance.

摘要: Abstract Objectives We aim to compare influenza vaccination coverages obtained using two different methods; a population based computerized registry and self-reported status as captured by survey. Methods The study was conducted in the Autonomous Community of Madrid (ACM), Spain, refers 2011/12 campaign. Information on according extracted from SISPAL database crossed with electronic clinical records primary care (ECRPC). Self-reported vaccine uptake subjects living ACM included 2011–12 Spanish National Health Survey (SNHS). Independent variables included: age, sex, immigrant presence high risk chronic conditions. Vaccination were calculated variables. Crude adjusted prevalence ratios computed assess concordance. Results 5,245,238 adults year 2011 an individual ECRPC 1449 adult interviewed SNHS October June 2012. weighted coverage for data 19.77% 15.04% registries resulting crude ratio (cPR) 1.31 (95% CI 1.20–1.44) so significantly overestimated 31% coverage. are always higher than when is stratified overestimation among men women, younger age groups, immigrants those without Both methods provide most concordant estimations target vaccine. Conclusions Self-report overestimates coverages. validity self-report seems be negatively affected socio-demographic absence Possible strategies must considered implemented improve both estimation methods.
