To determine the incidence of laparoscopic cholecystectomy (LC) and open cholecystectomy (OC) and some of their possible outcomes (complications, mortality, 30-day readmission) in the general population of senior citizens, we examined Medicare claims data for beneficiaries 65 years and older in eight states. Billing data for all cholecystectomies (ICD9-CM 51.22, 51.23) performed on an inpatient basis in those states on Medicare beneficiaries age 65 and older during fiscal year 1992 were examined. The incidence of LC in each state ranged from 2.1 to 3.2/1,000, whereas the incidence of OC ranged from 2.2 to 3.5/1,000. ⋯ Patients who underwent OC were more likely (9.2%) to be readmitted within 30 days than were LC patients (7.0%). LC seems to be at least as safe as OC in the elderly population. Analyzing Medicare claims data can be useful in uncovering geographic variations in cholecystectomy practice.

The effect of a triage and care system, which employs continued patient education, alternatives to emergency department (ED) care for nonemergent problems, and close cooperation between ED staff and the primary care physician on inappropriate ED use, was analyzed for three groups of patients: (a) Medicaid patients, all of whom had unrestricted access to the ED; (b) group A patients who required prior physician approval and copayments for all ED services; and (c) patients enrolled in group B who were responsible for copayments only and did not require prior physician approval for ED use. Two hundred ninety-nine (299) charts were prospectively reviewed for age, payer status, date, time of visit, diagnosis, outcome of visit, and severity of illness. ⋯ Medicaid patients were significantly younger than group A or B patients (P < 0.001) and had lower severity scores (P = 0.04). Our triage and care system failed to alter patterns of ED utilization for Medicaid patients.
