Financial impact of coronary stenting in emergency for acute coronary syndromes.

BACKGROUND Since the prospective payment system, health institutions have only specific payments for the emergency care in the emergency room. The direct urgent admissions in coronary care units for acute coronary syndrome (ACS) do not collect this complementary refund. For the patient's stay, hospital is remunerated with fixed national prices which are similar even in case of emergent or planed coronary revascularization when realized. AIMS To analyze and compare the financial impact between emergent and planed coronary stenting in the setting of ACS. PATIENTS AND METHODS This retrospective study was based on patients suffering from ACS who experienced emergent coronary stenting during the year 2005. On 154 patients, 127 were age-, sex- and diagnosis-related group (called "groupe homogène de malades" in the French Health Care system)-matched with 127 suffering from same ACS but with planed "ad hoc" coronary stenting. The overall charges (medical and paramedical team, pharmacy, biology, implantable coronary devices, radiology) were compared between the two groups. RESULTS Mean stay duration was 6.7 days and did not differ between the two groups. Mean financial retributions were significantly higher in the emergent group (7338 euro [6831-7846] IC95 vs 6509 euro [5994-7023]; p=0,02) but with a much more raised consumption (6810 euro [6283-7336] vs 5223 euro [4632-5814]; p=0,001). This overcost was due especially to drugs and biological expenses. The hospitalization payments did not cover the overall expenses for 25% of the patients' stays (N=64) among whom 39 have had emergent coronary stenting (30.7%, p=0.04). Among the different GHM, the most important difference was observed in non-STEMI without complication with a negative receipts/costs ratio for 37.8% of the stay with coronary stenting in emergency. CONCLUSION The application of the recent guidelines for coronary revascularization in the management of ACS represents a financial venture for hospital institutions. The engaged charges for emergent coronary stenting are covered with difficulties contrary to planed revascularization.
