Comparing Prevalence Estimates From Population-Based Surveys to Inform Surveillance Using Electronic Health Records

The two one-sided t test (TOST), commonly used by the pharmaceutical industry to test whether one drug works as well as another, also has important applications in epidemiology. Electronic health record (EHR) systems provide a new opportunity to use health care data for population health surveillance. Population health estimates from EHR data are most commonly validated against estimates from surveys using statistical tests of whether estimates are different (such as the t-test), but these tests can produce meaningless results when sample sizes are large. We explored a novel application of a method to assess equivalence, the TOST, to determine whether estimates from two population-based surveys were statistically equivalent. This work will guide the use of equivalence testing for validating EHR-based population health estimates.

Factors Associated With Parents’ Intent to Vaccinate Adolescents for Human Papillomavirus: Findings From the 2014 National Immunization Survey–Teen

Among parents of US adolescents ages 13 to 17 years, maternal education emerged as the strongest predictor of parental intent to obtain human papillomavirus vaccination for their children. Researchers analyzed data on 10,354 adolescents ages 13 to 17 years from the 2014 National Immunization Survey–Teen. Among unvaccinated adolescents, mothers with less than a high school diploma, Hispanic ethnicity, and having a health care provider recommend the vaccine were significantly associated with parents’ intention to have their adolescent child vaccinated within the next 12 months. In addition, non-Hispanic black race was a significant predictor of parents’ intent to vaccinate for boys.
