Abstract

Background: Since 1960, the Advisory Committee on Immunization Practices has recommended influenza vaccination for adults with certain high-risk conditions because of increased risk for complications from influenza infection. We assessed national influenza vaccination among persons ages 18-64 years with high-risk conditions.

Methods: We analyzed data from the 2012 and 2013 National Health Interview Survey. The Kaplan-Meier survival analysis procedure was used to estimate the cumulative proportion of influenza vaccination among adults ages 18-64 years with high-risk conditions. Potential missed opportunities for influenza vaccination were also evaluated. Multivariable logistic regression and predictive marginal analyses were conducted to identify factors independently associated with vaccination.

Results: Overall, 39.9 million adults ages 18-64 years (18.9%) had at least one high-risk condition. For adults ages 18-64 years with high-risk conditions, overall influenza vaccination coverage was 49.5%. Coverage among adults 50-64 years of age was significantly higher compared with those ages 18-49 years (59.3% vs 39.0%; P <.05). Among adults ages 18-64 years, coverage was 46.2% for those with chronic lung diseases, 50.5% for those with heart disease, 58.0% for those with diabetes, 62.5% for those with renal disease, and 56.4% for those with cancer. Overall, 90.1% reported at least one visit to a health care setting where vaccination could have been provided. Among adults ages 18-64 years with high-risk conditions, older age, being female, Hispanic ethnicity or Asian race, having one or more physician visits, a regular physician for health care, health insurance, and having ever received pneumococcal vaccination were independently associated with a higher likelihood of influenza vaccination. Being widowed/divorced/separated or never married and not being employed were independently associated with a lower likelihood of influenza vaccination.

Conclusions: Influenza vaccination coverage varies substantially by age and high-risk conditions but remains low. Approximately 50% of those with high-risk conditions remain unvaccinated. Health care providers should ensure they routinely assess influenza vaccination status, and recommend and offer vaccines to those with high-risk conditions.
