Abstract

Introduction: National reports suggest that Hispanic patients may underutilize influenza and pneumococcal vaccination, although studies sometimes conflict on this point. A clearer picture of adult immunization utilization in older Hispanic patients is necessary to ensure equity in adult vaccinations. Methods: Using electronic health records from 648 community health centers (CHCs) across 21 states, we compared English-preferring Hispanic patients, Spanish-preferring Hispanic patients, and Non-Hispanic White (NHW) adults aged ≥50 years across five outcomes between 2012–2017: (1) Odds of ever receiving pneumococcal vaccination after age 65, (2) Odds of ever receiving ≥2 pneumococcal vaccinations for those ≥65, (3) odds of vaccination between the ages of 50 and 64 for those with diabetes or heart disease, (4) odds of influenza vaccine, and (5) annual rate of influenza vaccination. Results: Of our total study sample (N = 143,869), 85,562 were age 50–64 during the entire study period, and 65,977 were ≥65 at some point during the study period. In patients aged 50–64, Spanish-preferring Hispanic patients were more likely to have ever had an influenza vaccination (covariate-adjusted odds ratio [aOR] = 1.33, 95% CI = 1.29–1.37), had higher rates of annual influenza vaccination (covariate-adjusted rate ratio [aRR] = 1.41, 95% CI = 1.38–1.44), and higher odds of pneumococcal vaccination (aOR = 1.87, 95% CI = 1.76–1.98) than NHW patients. These findings were similar in Spanish-preferring Hispanic patients ≥65. English-preferring Hispanics ≥65 were less likely than NHW patients to ever have an influenza vaccination (aOR = 0.91, 95% CI = 0.85–0.98) and to have ever received at least one (aOR = 0.92, 95% CI = 0.86–0.99) or two (aOR = 0.86, 95% CI = 0.77–0.95) pneumococcal vaccine doses. Conclusions: In a multistate CHC network, Spanish-preferring Hispanic patients were more likely to receive influenza and pneumococcal vaccinations than NHW patients; older English-preferring Hispanic patients were often less likely than NHW patients to receive these vaccinations. In vaccine initiatives, English-preferring Hispanic patients may be at higher risk of vaccination inequity.
