IPCS patients reported greater satisfaction with their care experience and providers' communication, had fewer ICU admissions on readmission, and lower total health care costs following hospital discharge.

The CHCC model resulted in fewer hospitalizations and emergency visits, increased patient satisfaction, and self-efficacy, but no effect on outpatient use, health, or functional status.

Group visits for chronically ill patients reduce repeat hospital admissions and emergency care use, reduce cost of care, deliver certain preventive services more effectively, and increase patient and physician satisfaction.

A mailed questionnaire achieved a high response rate, and the information collected produced an effective model predictive of hospitalization in the short term. Four easily ascertained pieces of information identify those patients older than age 81 at increased risk.
