Bottom-up analysis of the case costs of stem cell transplantation and selected chemotherapies

Abstract

Up to now, reliable data has not been available on the actual costs of treating oncological patients. However, such data material is urgently required in view of the institution of the health service reform with the concomitant introduction of the G-DRG remuneration system. The medical services and their costs for 66 patients comprising several stays in hospital, part-time hospitalization and outpatient visits to the clinic categorized "establishment of the diagnosis", "stem cell therapy (SCT)" and "chemotherapy" were recorded in parallel to treatment over a time period of three months. It was thus possible to relate a cost volume of 2.7 million euro to more than 2800 nursing days (full and partial hospitalization) and more than 500 outpatient visits. All pertinent costs were collated with the various stays/movements of the patients over 100 calendar days. This was very largely possible thanks to a sophisticated costing and setting off of payments within the hospital on the part of the service providers in the hospital in direct allocation to patients and the third-party payers. Additionally, partial and full surveys as well as questionnaires enabling allocation to the individual case as far as possible, especially the staff requirement, were used. A breakdown of the costs in terms of the patient nursing days was only effected in marginal areas such as the "hotel function" or the general administrative costs. A further subdivision of the stays and movements as well as the phases of the stays applied to the service or the treatment progress above and beyond the areas of treatment. In the case of chemotherapy, a distinction was therefore made between "protocol blocks" and "stays due to complications" and in the case of SCT inter alia even individual phases such as "conditioning". It is problematical to represent these patients within an DRG case flat rate system because of frequent and very divergent residence periods with regard to services and costs. The multiplicity of treatment sessions is manifested in the compact "establishment of the diagnosis" to determine a therapy protocol which entails very elaborate inpatient measures under hospitalization, in the expensive and individual "stays due to complications" which usually take place between the "chemotherapy blocks", and the expensive long-term care of the SCT patients after the end of the residence limit (GVD). Owing to the small and divergent numbers of cases in Germany (2000 new patients in 50 centers and 330 SCT per year) and per center, this problem cannot be dealt with by means of a quantity compensation argumentation, as is doubtless justified elsewhere. The actual individual case costs of oncological patients would be 166,72 euro; per outpatient contact and covered by 459,30 euro; per day of hospital care and 808,20 euro; per inpatient treatment day (admission plus discharge day calculated separately and comprised stem cell transplantation patients beyond the residence limit) is covered. The level of the currently applicable case flat rate payments for stem cell transplantations and heterologous donors, mismatched heterologous donors and family donors appear appropriate in relation to the GVD. (The true costs of all oncological patients would indeed be even higher if the GOA payment of the ILV did not only relate to a house-internal low pricing of the GOA scoring value, but would also relate to HLA typing, unpaid physician overtime and the costs of the study centers to the individual cases. From 2002, there will be changes consequent on the judgment of the European Court that stand-by is working time, so that more physicians must be employed and there are expensive changes in the infrastructure owing to the need for a GMP clean area laboratory to process stem cells according to the medical products law.) The indeterminate bound-aries between the three treatment categories place in question the dual financing by the Panel Doctor's Association and the health insurance funds and indicate that a total-sum remuneration appears appropriate.
