This case study examines the trends in new Medicaid and SCHIP enrollment in California from 2000 through 2004. In particular, the authors were interested in examining the potential links between new enrollment trends and major outreach strategies or policy changes that took place in California at the state and local level, especially those associated with the Covering Kids & Families® (CKF) grants.
Ideally, they would examine such links through a formal impact analysis that estimates the effect of individual policy changes or outreach efforts on the number of children enrolling in Medicaid or SCHIP. This type of analysis was not possible, however, because many of the outreach efforts and policy changes occurred at the same time. In addition, no state or other geographic area is a defensible comparison group for a more rigorous analysis.
The case study approach, which combines exploratory data analysis with in-depth key informant interviews, allowed the authors to assess the potential influence that major outreach efforts or policy changes have had on new enrollments.
