Preeclampsia in Switzerland: a cost analysis in two hospitals

Aim: Preeclampsia is a serious complication of pregnancy that occurs in approximately 2.3% of all pregnancies in Switzerland. The aim of this study was to determine inpatient costs based on actual services in suspected and confirmed cases of preeclampsia in two Swiss hospitals (University Hospital Basel, Lucerne Cantonal Hospital) for the year 2016.Methods: Costs for patients with suspected or diagnosed preeclampsia were determined based on the databases of the finance and controlling departments. The cases were identified according to ICD-10 codes and were divided into three main categories: (1) patients with suspected preeclampsia who were discharged without delivering; (2) patients with diagnosed preeclampsia followed by vaginal induction; (3) patients with diagnosed preeclampsia followed by cesarean delivery.Results: A total of 301 cases were included in the analysis, of which 36 (12%) were hospitalized with suspected preeclampsia and discharged after a few days without delivering. Costs for cases of suspected preeclampsia were the lowest, averaging CHF 7,159/EUR 6,658 (95% CI: CHF 5,361/EUR 4,986; CHF 8,958/EUR 8,331), followed by CHF 12,124/EUR 11,275 (95% CI: CHF 10,401/EUR 9,673; CHF 13,950/EUR 12,974) for cases of preeclampsia with vaginal delivery, and CHF 19,352/EUR 17,997 (95% CI: CHF 17,342/EUR 16,128; CHF 21,507/EUR 20,002) for preeclampsia with cesarean section. Overall medical costs were CHF 4.7 (EUR 4.4) million. In all patient groups, the actual patient costs exceeded the DRG revenue that inpatient care providers receive from payers for providing services. The budget deficit was seen in both hospitals, although the magnitude of the deficit was different.Limitation and conclusion: This is the first study to analyze costs for preeclampsia in Switzerland. It would be desirable if this cost analysis was to be performed in other hospitals in order to achieve greater representativity for Switzerland.
