Cost of extracorporeal membrane oxygenation: evidence from the Rikshospitalet University Hospital, Oslo, Norway.

OBJECTIVE: The main objective is to describe and analyse hospital costs of the extracorporeal membrane oxygenation (ECMO) procedure. STUDY SAMPLE AND METHODOLOGY: Between January and December 2007, 14 ECMO patients were consecutively included in the study. Costs at the patient level were registered prospectively, while overhead costs were registered retrospectively. Patient costs were obtained from patient records and time-motion studies and included personnel resources, diagnostic and laboratory tests, radiology and operating room procedures, medication and blood products. Overhead costs were allocated to clinical departments and further to the individual patients by predefined keys. To achieve estimates of total costs, patient-specific costs and patient-specified overhead costs were summarised. RESULTS: The mean estimated cost for the ECMO procedure was 73,122 USD (SD 34,786) and median 62,545 USD (range: 34,121-154,817). The mean estimated total hospital costs, including pre- and post-ECMO procedures, was 213,246 USD (SD 12,265), median 191,436 USD (range: 59,871-405,497). On average, 82% of costs for the total hospital stay were related to personnel use, and blood products constituted 7%, lab and radiology 2.5%, disposable items 3% and medication 1.5%. The mean duration of an ECMO procedure was 9.5 days (range: 4-23 days) and the average total length of stay in hospital was 51.5 days (range: 6-123 days). The cost data were converted from Norwegian kroner (NOK) to US dollars (USD), with an exchange rate of 1 USD=5.5 NOK. CONCLUSION: ECMO procedure is a resource-demanding procedure.

[High-risk pregnancy, costs and DRG reimbursement]. / Risikofødende, kostnader og DRG-refusjon.

BACKGROUND: The aim of this study was to measure actual costs of delivery of women with high-risk pregnancies in Norway. We calculated the cost difference between Caesarean section delivery and vaginal delivery and compared costs and the reimbursement received by hospitals. The present Norwegian financial system for hospitals has two components: a government reimbursement based on diagnosis-related groups (DRG) covering, in principle, half of hospital costs, and a basic budget received as a block grant. MATERIAL AND METHOD: The study included 75 high-risk pregnant women. We used a prospective, individual bottom-up method based on: 1) hospital stay and the resources required, 2) operating theatre costs, 3) other major procedures, and 4) material and medication costs. Overhead costs (basic and general costs) were added on the basis on five key variables: 1) number of admittances (length of stay), 2) number of discharges, 3) number of employees, 4) floor space, and 5) number of PCs. The total cost for each patient was compared with the reimbursement received. RESULTS: We found that the reimbursement did not cover actual costs. Calculations were made for Caesarean and vaginal deliveries respectively: Mean cost of a Caesarean delivery was NOK 96,556, compared to a DRG reimbursement of NOK 47,137; mean cost of a vaginal delivery was NOK 62,136, with a DRG reimbursement of NOK 27,146.
