Validity of self-reported pneumococcal vaccination status in the elderly in Spain.
ABSTRACT The objective of this study was to evaluate the validity of information reported by the elderly on 23-valent pneumococcal polysaccharide vaccine (23vPPV) vaccination status. A cross-sectional, observational study was carried out in patients aged >or=65 years admitted to five Spanish hospitals. Data on 23vPPV vaccination history were obtained through interview of the patient or close relative and review of written medical information. The validity of the patient self-report was compared to the written medical information by calculation of the sensitivity, specificity, concordance, positive predictive value (PPV) and negative predictive value (NPV). A total of 2484 patients were initially included of whom 1814 patients (73%) responded about their vaccination status. The global sensitivity of the patient self-report was 0.74 and the specificity 0.95. The PPV was 0.92, the NPV 0.84 and the concordance 87. Vaccination cards and centralized vaccination registries in primary health care centres and hospitals should be potentiated in order to ensure that neither more nor less vaccinations are administered than are necessary.

ABSTRACT: Otitis media is one of the most worldwide prevalent diseases that affects children. The socioeconomic costs may exceed 3.5 billion dollars a year in the United States alone in direct and indirect costs. If a vaccine can be developed that will decrease 1% of the illness this would be significant in this country and probably even more valuable in less developed countries.The Pediatric Infectious Disease Journal 02/1989; 8(1 Suppl):S11-4. · 3.57 Impact Factor

ABSTRACT: Behavioral risk factor surveillance system (BRFSS) is the primary surveillance tool for the ongoing measurement of state-specific delivery of pneumococcal polysaccharide vaccine. This study is the first validity assessment of self-reported pneumococcal vaccination status in a population-wide BRFSS survey. A subset of respondents to the sickness prevention achieved through regional collaboration (SPARC) BRFSS survey, which was conducted from June to September 1997 in a four-county area were assessed. Self-reporting of pneumococcal vaccination status was validated either by matching to Medicare claims or by reviewing of medical records. Self-reporting of pneumococcal vaccination had a sensitivity of 75% and a specificity of 83%. We conclude that self-reporting of pneumococcal immunization is a moderately sensitive and specific measure and that population-based surveys in the community can be validated when undertaken in collaboration with a local health care agency.Vaccine 02/2005; 23(8):1015-20. · 3.49 Impact Factor

ABSTRACT: Self-report of polysaccharide pneumococcal vaccination is not thought reliable because of the increased risk of adverse events from inadvertent re-vaccination in elderly people. Some studies suggest a high sensitivity of self-report and hence a low risk of adverse events if vaccination is administered when medical records are unavailable. Self-report of pneumococcal and influenza vaccination in a sample of >64-year-olds in the United Kingdom was compared with information in their medical records. Self-report of pneumococcal vaccination, in contrast to some of the other studies had a low sensitivity. The findings here support the need for accurate knowledge of prior vaccine status before offering the polysaccharide pneumococcal vaccine. The study also confirms that self-report of influenza vaccination could be relied upon if rapid knowledge of uptake is required.Epidemiology and Infection 01/2007; 135(1):139-43. · 2.87 Impact Factor
