A new keyword search accurately identified patients eligible for pneumococcal vaccination. This method revealed only 63% of elderly patients received the vaccine, highlighting a significant gap in immunization coverage for this high-risk group.

Area of Science:

  • Public Health
  • Preventive Medicine
  • Geriatrics

Background:

  • Healthy People 2010 aimed for a 90% pneumococcal vaccination rate in elderly individuals.
  • Pneumococcal disease poses a significant health risk to the aging population.
  • Achieving high vaccination rates is crucial for public health in older adults.

Purpose of the Study:

  • To develop and validate a keyword search strategy for identifying patients eligible for pneumococcal vaccination.
  • To establish a computerized registry for pneumococcal immunizations.
  • To assess the current pneumococcal vaccination coverage in an elderly primary care population.

Main Methods:

  • A keyword search was designed using pharmacy orders for Pneumovax as the gold standard.
  • The search strategy was validated against a dataset to determine its accuracy in capturing vaccinations.

  • Eligible patients were identified and added to a computerized immunization registry.

    • Main Results:

    • The keyword search demonstrated high efficacy, capturing 98% of vaccinations in the validation dataset.
    • A total of 4,768 patients were identified and enrolled in the immunization registry.
    • The study found a pneumococcal vaccination rate of 63% among primary care patients over 65.

    Conclusions:

    • The developed keyword search is an effective tool for building pneumococcal vaccination registries.
    • A substantial gap exists in pneumococcal vaccination coverage, with 37% of the high-risk elderly population remaining unvaccinated.
    • Targeted interventions are needed to increase pneumococcal vaccine uptake in older adults.
