2. A pre-post study to determine the impact of the Navigators Program on service patterns and estimated costs (1 year prior and 1 post). 1. To identify and calculate the differences in total visits and costs from pre-Navigator service to post-Navigator service by type of service for the treatment group. 2. To identify and calculate the differences in total visits and costs from first year to second year by type of service for the comparison group. 3. To compare differences between the two groups by type of service and cost to determine the impact of the program. Study

4. CHIP UNIVERSE Referral Criteria by groups before June 2007: a) No referrals. b) Visited ED during office hours multiple times or had multiple siblings visited ED. c) Inappropriate use of ED. d) All members who’s enrollment was to expire. Navigator population

6. NAVIGATOR GROUP: 1. Have been continuously enrolled with the Medicaid/CHIP program from April 2005 through March 2008.

Served by a Navigator between April 2006 and March 2007; and 3. Be a resident of Harris County throughout the study period (preferred), if can be determined. STUDY INCLUSSION CRITERIA

7. CHIP UNIVERSE Matched to Navigator group by: a) Age b) Gender c) Race/Ethnicity d) ED visits e) Non-chronic conditions. f) Same inclusion criteria as treatment group (not served by navigators) Control group
