Details and patient eligibility

About

Compare two care management support program models on medical costs and utilization.

Enrollment: 174,120 patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• All employees, dependents and retirees in one of seven large employer groups, including a state university system, a state employee group, two manufacturing companies, a natural resource extraction company, a public educational service agency, and a nonprofit multiple employer association for independent colleges were eligible for inclusion.

Exclusion criteria

• no financial information was available from their facility and professional claims;
• they were in an employer sub-group ineligible for care support services;
• they asked not be to contacted or were deceased;
• gender information was missing from their eligibility files;
• their claims data from the year prior to the start of the study indicated diagnoses of HIV, AIDS, end-stage renal disease (ESRD), organ transplants, or necrotizing fasciitis (intended to improve the likelihood of a balanced distribution of costs and conditions); OR
• they were in an employer sub-group with less than four months of enrollment prior to the study start date (resulting in too little information for stratification).

Trial design

174,120 participants in 2 patient groups

Usual Support Group

Active Comparator group

Description:

Predictive models in the Usual-Support Group were aimed at identifying individuals through medical claims and administrative data (such as hospitalization notification). The output of the predictive models is a rank-ordered, or stratified, list of individuals who have support needs. These lists were then used to generate outbound mail, interactive voice response (IVR) calls or calls by health coaches.

Treatment:

Behavioral: Usual-Support

Enhanced Support Group

Experimental group

Description:

The Enhanced-Support Group intervention used more sophisticated predictive models, more extensive outreach to engage individuals, and provided tighter feedback loops to inform the care support process.

Treatment:

Behavioral: Enhanced Support
