Doel van het onderzoek is om te bepalen of patiënten met pijn op de borst die naar een cardioloog worden verwezen vanuit een organisatie met poortwachter verschillen van patiënten die bij een organisatie zonder poortwachter vandaan komen

OBJECTIVE: To determine whether patients with chest pain referred to a cardiologist from a gatekeeper managed care organization differ from those referred from an open-access managed care organization. STUDY DESIGN: Retrospective study using clinical and claims data from a cardiac network database. PATIENTS AND METHODS: We reviewed data from 1414 patients with chest pain or angina who were referred to a cardiologist between January 1, 1995, and June 30, 1996. We examined baseline clinical characteristics and subsequent physician practice patterns for these patients, who were referred from either a primary care gatekeeper model (n = 490) or an open-access model (n = 924). RESULTS: Although twice as many open-access patients were referred to a cardiologist, there were no differences in patient demographics or clinical characteristics at the time of referral. Cardiologists ordered similar diagnostic tests for patients from both types of managed care plans, and gatekeeper patients did not have a higher rate of abnormal tests. Rates of cardiac catheterization, coronary angioplasty, myocardial infarction, and hospitalization were similar in both groups. A significantly higher percentage of gatekeeper patients received a cardiac catheterization on the day of referral (7% versus 1%; P = .05). Open-access patients were significantly more likely to continue to be seen by a cardiologist (44% versus 28%; P < .01). Cardiology professional charges per patient were lower among gatekeeper patients ($972 +/- 1398 versus $1187 +/- 1897; P = .06), and total cardiology professional charges were significantly lower for the gatekeeper group because of the smaller number of patients seen. CONCLUSIONS: The type of cardiology services provided to patients with chest pain was not affected by the primary care administrative structure of the managed care organization, but the higher volume of patient referrals from the open-access plan may be an important consideration for cardiology practices participating in capitated contracts. The lower volume of referrals and coordination of care suggest potential cost advantages for the gatekeeper model
