The OASIS study is a federally funded project that evaluates the use of features of the New York State Immunization Information System (NYSIIS), by various types of primary care practices.
The use of immunization information systems (IIS) has expanded rapidly over the past decade. These systems are not only repositories of individual children’s immunization data, but generally have a number of features that can assist primary care practices in achieving high immunization levels. Little is known about the extent to which these features are currently used in primary care. Additionally, in the last several years, practices have increasingly switched from paper patient records to electronic health records and, as a result, it is likely their patterns of IIS use have changed as well.
To determine how practices currently use the New York State Immunization Information System (NYSIIS) in their immunization efforts and to learn about preferences for expanding those efforts.
- Evaluate the use of features of NYSIIS by primary care practices
- Discern factors that impact how NYSIIS is used in settings with and without electronic health records
- Determine how best to promote the use of IIS features and functionality
Phase 1: Survey
- Invitation sent to Pediatric and Family Medicine practices registered with NYSIIS
- Content included questions related to:
- Demographic features of the practice
- Features of immunization delivery within the practice
- Electronic health record use (current and anticipated)
- NYSIIS use
- Current and contemplated quality improvement activities related to childhood and adolescent immunization
Phase 2: Key Informant Interview (current)
- Telephone interview with practices' NYSIIS administrator
- Explore in more depth the survey responses and gauge perspectives about use of NYSIIS for immunization quality improvement
- Practices will be selected from a broadly representative sample
- Practices from urban, suburban, and rural settings
- Practices that use and do not use EHRs
- Pediatric and family medicine practices
Phase 3: Intervention
- Design, implement and evaluate strategies to routinely use NYSIIS to:
- Immunization coverage in the office setting
- Efficiency in routine office practices
- Missed opportunities for vaccination in the office setting
- Administration of extra immunizations in the office setting
