[Economic Analysis of Treatment Courses for Patients Over the Age of 80 Years at a Surgical Maximum Care Centre]. / Ökonomische Analyse des Behandlungsverlaufs bei über 80-jährigen Patienten an einer Klinik der chirurgischen Maximalversorgung.

BACKGROUND: The demographic change in Germany with an aging population and the resulting necessity of adequate surgical care for older patients was lately discussed with concern. One major aspect is the estimated higher treatment costs in the care of the elderly. MATERIALS AND METHODS: InEK data from all cases of patients over the age of 80, who were treated and discharged from 2008 to 2012 as inpatients at the Department of General, Visceral, Vascular and Thoracic Surgery at the Charité - Universitätsmedizin Berlin, Campus Mitte, were analysed. Of a total of 13,612 patients 626 patients were over the age of 80. Their lengths of stay, mode of discharge and discharge management as well as costs and reimbursements according to the relevant diagnosis-related groups were analysed. RESULTS: Cases of elderly patients amounted to a stable 5 % of all cases from 2008 until 2012. Their mean length of stay was 14 (median, 9), range, 1-129 days. 80 % of patients could be regularly discharged, 9 % died, 8 % were transferred to another hospital, 2 % discharged into a nursing home and 1 % into a rehabilitation centre. The elderly patients had a patient clinical complexity level of mean 2.84. Costs per day amounted to a mean 778 (median: 627) €, range: 306-7740 €, total costs to 10,686 (median: 5140) €, range: 368-186,059 €. The mean deficit was 491 (median: 176) € per patient, range: - 30,470-75,144 €. The discharge management was significantly different in comparison to patients under the age of 80 with respect to avoidance of discharge at the weekend. CONCLUSION: Patients over the age of 80 are a relevant group in surgery. They have an increased perioperative risk, but patients should not be denied surgery solely because of their age. The perioperative management of the elderly has to be of maximum standardised quality. From an economic perspective it can be stated that elderly patients currently pose no exceptional financial risk to a surgical department, but contribute relevantly to the turnover, whereby special attention has to be paid to an early structured discharge management.

[Hyperthermic intraperitoneal chemotherapy in the German DRG system. Analysis of case cost calculations of a maximum care university]. / Hypertherme intraperitoneale Chemotherapie im G-DRG-System. Analyse der Fallkostenkalkulationen eines universitären Maximalversorgers.

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) offers patients with peritoneal cancer of various origins the chance of a relevant increase in life expectancy. These cases are very complex from a medical viewpoint and very expensive from an economical aspect. An analysis of case cost calculations was performed to find out whether this procedure can on average be carried out cost-effectively by a maximum care university. MATERIALS AND METHODS: All cases from 2008 in which HIPEC was carried out were analyzed. The types of main diagnosis, secondary diagnoses, procedures, times from incision to suture and hospital stay were analyzed. On the basis of the case costs the proceeds and marginal returns were calculated from the diagnosis-related groups (DRGs) and additional remuneration when applicable. The causes of positive and negative marginal returns were explained using the InEK cost matrix. RESULTS: In 18 patients there were 9 different main diagnoses and 7 different "main procedures" (from a surgical perspective the most resource intensive procedures) and a total of 10 different DRGs were identified in the grouping algorithm. With an average of 2 operations (range 1-7) per patient the summed incision-to-suture time was 423 min (170-962 min). The patients stayed on average 6.4 days (1.3-17.6 days) in intensive care. The average case cost was 21,072€ (range 8,657-55,904€) and the proceeds 20,474€ (6,333-37,497€). Each case had on average a debit balance of 598€ (range from 11,843€ profit balance to 18,407€ debit balance) with an assumed base rate of 2,786€. The causes for positive or negative marginal profits were mostly operating times, incision-to-suture times and duration of intensive care. CONCLUSIONS: The proceeds showed on average a deficit of only 3% compared to the costs. The operating times must be decreased by optimization particularly of the preoperative approach. Interventions should be carried out in one stage only and the intraoperative connecting and waiting times should be reduced in order to reduce the incision-to-suture times.
