This study evaluated the accuracy of data on vaccination rates and quantified the degree of under-estimation of influenza and pneumoccocal vaccination coverage levels for each Indian Health Services (IHS) Area. This allows the IHS and Area offices to more accurately measure influenza and pneumoccocal coverage. This in turn allows IHS to better identify possible barriers to immunization with influenza and pneumoccocal and develop strategies to improve coverage. Immunization is one of the most cost-effective public health measures, and results in dramatic reductions of morbidity and mortality associated with vaccine-preventable diseases. Because of this, increasing both influenza coverage and pneumoccocal coverage among adults age 65 years and older is a goal of Healthy People 2010. IHS researchers: (1) selected a random sample of patients from each Area, 65 or older who had at least one clinic visit between July, 2003 and June, 2004; reviewed available data to determine how many patients received influenza vaccination; and conducted chart reviews on patients with no recorded influenza and/or pneumoccocal vaccination to determine if influenza and pneumoccocal vaccination was documented in the chart.
Researchers found that there were data in charts that were missing from the Resource and Patient Management System data base. Researchers recommended that providers should be trained to properly enter information into the data base. Pneumoccocal vaccine coverage varied considerably facility from 67 to 92 percent. The IHS could increase vaccination rates by offering vaccines during every visit during the flu season.
