Adult immunization rates remain low, failing to meet national targets. The study found the Adult Immunization Status (AIS) measure feasible for healthcare organizations to improve vaccination rates, especially for underserved populations.
Area of Science:
- Public Health
- Health Services Research
- Quality Improvement
Background:
- Adult immunization rates in the U.S. are suboptimal and have been impacted by the COVID-19 pandemic.
- Existing national targets for adult vaccination coverage are not being met.
- Routine healthcare services, including vaccinations, were disrupted during the pandemic.
Purpose of the Study:
- To evaluate the feasibility of the National Committee for Quality Assurance's Adult Immunization Status (AIS) measure for use by healthcare organizations (HCOs).
- To determine if the AIS measure can be leveraged as a strategy to enhance adult immunization rates.
- To identify opportunities and barriers for implementing the AIS measure within HCOs.
Main Methods:
- Quantitative analysis of deidentified electronic health record (EHR) data from three HCOs.
- Qualitative interviews with stakeholders to explore implementation factors.
- Assessment of data availability within HCOs for AIS measure calculation.
Main Results:
- Data required for the AIS measure are available within HCOs.
- Measure performance can be improved with supplemental data from external sources like immunization registries.
- Adult immunization rates are low, with significant disparities observed among Black/African American patients, Medicaid enrollees, and uninsured individuals.
Conclusions:
- The AIS measure is feasible for implementation in medical groups.
- Leveraging the AIS measure has the potential to drive quality improvements in adult immunization rates.
- Implementation requires careful consideration, especially regarding provider accountability for measure performance.
