Patient preferences for palliative treatment of locally advanced or metastatic gastric cancer and adenocarcinoma of the gastroesophageal junction: a choice-based conjoint analysis study from Germany.

BACKGROUND: Decisions on palliative chemotherapy (CT) for locally advanced or metastatic gastric cancer (mGC) require trade-offs between potential benefits and risks for patients. Healthcare providers and payers agree that patient-preferences should be considered. We conducted a choice-based conjoint (CBC) analysis study in pre-treated patients from Germany with mGC or locally advanced or metastatic adenocarcinoma of the gastroesophageal junction (mGEJ-Ca), to evaluate their preferences when hypothetically selecting a CT regimen. METHODS: German oncologists and gastroenterologists were contacted to identify patients with mGC or mGEJ-Ca who had completed ≥2 cycles of palliative CT in first or later lines of therapy (CT ongoing or complete). The primary objective was to quantify patient preferences for palliative CT by CBC analysis. Six in-depth qualitative interviews identified 3 attributes: treatment tolerability, quality of life in terms of ability of self-care, and additional survival benefit. The CBC matrix was constructed with 4 factor levels per attribute and each participant was presented with 15 different iterations of these levels. A minimum of 50 participants was needed. Consenting patients completed the CBC survey, choosing systematically among profiles. CBC models were estimated by multinomial logistic regression (MLR) and hierarchical Bayesian (HB) analysis. Estimates of importance for each attribute and factor-level were calculated. RESULTS: Fifty-five patients participated in the CBC survey (78.2% male, median age 63 years, 81.8% currently receiving CT). Across this sample, low treatment toxicity was ranked highest (44.6% relative importance, MLR analysis), followed by ability to self-care (32.3%), and an additional survival benefit of up to 3 months (3 months 23.1%, 2 months 18.3%, 1 month 11.2%). The MLR analysis showed high validity (certainty 37.9%, chi square p < 0.01, root-likelihood 0.505). The HB analysis yielded similar results. CONCLUSIONS: Patients' preferences related to a new hypothetical palliative CT of mGC or mGEJ-Ca can be assessed by CBCanalysis. Although in real-life, patients initially need to decide on CT before they have any experience, and patients' varied experiences with CT will have impacted specific responses, low toxicity and self-care ability were considered as most important by this group of patients with mGC or mGEJ-Ca.

Burden of illness imposed by severe sepsis in Germany.

Sepsis is a systemic response to severe infection in critically ill patients and is among the most frequent causes of death in intensive care medicine. Every year between 44,000 and 95,000 persons suffer from this illness in Germany. With the help of a retrospective electronic chart analysis in three adult ICUs of three university hospitals we calculated by a bottom-up approach the direct costs of these patients yielding per patient costs of 23,297 euros on average. Linking the direct costs per patient with the incidence data, the total direct costs for severe sepsis in Germany per year were estimated to range from 1,025 to 2,214 million euros. Direct costs, however, were found to make up only about 28% of the burden of disease of severe sepsis. The indirect costs range between 2,622 and 5,660 million euros. Productivity loss due to premature death does account for the largest part of the indirect costs. In conclusion, severe sepsis imposes annual costs between 3,647 and 7,874 million euros to the German society.

Length of hospital stay and associated costs for olanzapine vs. haloperidol in the treatment of schizophrenia relapse in Germany.

We examined the number of days spent in hospital due to a relapse of schizophrenia and the associated costs for patients treated with olanzapine or haloperidol. Twenty-one German psychiatric hospitals participated in this retrospective study. Data on the last hospitalisation following a relapse of schizophrenia were documented for equal numbers of patients on olanzapine and haloperidol. Matching for time since diagnosis and severity of symptoms was performed. Data were collected on 136 matched pairs. Total length of time spent in hospital was the same on average for patients in both groups (median about 5 weeks), but olanzapine patients spent nearly 1 week less in the in-patient setting than haloperidol patients, resulting in a saving of Euro 411 per patient. Our findings are consistent with those of randomised clinical trials in concluding that olanzapine is preferable to haloperidol in terms of the direct cost of treating schizophrenia.
