BACKGROUND:
Ohio’s immunization registry, ImpactSIIS, began accepting data from the private sector in February 2002. Over eight million immunization histories have been loaded into the system. Ohio’s Immunization Program conducts AFIXs in private provider offices by pulling charts and manually entering data into CASA.

OBJECTIVE:
Determine the method(s) to use for conducting assessments using ImpactSIIS data.

METHOD:
The methods researched were: using ImpactSIIS’s existing CASA Report function; using an electronic list of names and dates of birth and electronically matching them with data in ImpactSIIS; and randomly selecting 100 names from each age range, searching in ImpactSIIS, then manually entering the data into CASA.
Two private provider sites were selected. Site A began using ImpactSIIS in January 2003 with historical immunization information pre-loaded. Site B began in March 2003 without pre-loaded historical information. Site B enters historical information when current shots are entered.

RESULT:
The strengths and weaknesses of each method were identified. Not all methods will work for all provider sites. Each site needs to be evaluated to determine the best method to use. Additional follow-up will be needed to refine the methods of data extraction.
After the data from ImpactSIIS was entered into CASA, a missing immunizations report was created. Staff visited each site and entered missing chart data. After including the missing chart data, immunization rates at both provider sites increased, by 6.67% at Site A and 26.38% at Site B.

CONCLUSION:
Flexibility in the choice of available methods of data extraction is crucial. How sites are set up and utilize the registry can impact the ability to use certain methods. The limitations of the data being reviewed must be taken into consideration. Having electronic data may not completely eliminate the need to pull charts.

LEARNING OBJECTIVES:
Participants will be able to describe different options for using registry data in conducting CASA assessments.
