Time-dependent cost comparison and health economic impact analysis of second-line interventions for transplant-ineligible patients with relapsed or refractory diffuse large B cell lymphoma.

OBJECTIVES: Novel interventions (axicabtagene ciloleucel [axi-cel], lisocabtagene maraleucel [liso-cel], tafasitamab-lenalidomide [Tafa-L], polatuzumab-rituximab-bendamustine [pola-BR]) improve clinical outcomes in second-line (2 L) treatment of transplant-ineligible patients with early relapse or refractory (R/R) diffuse large B cell lymphoma (DLBCL). The costs vary depending on the respective treatment regimen and the treatment duration, difficult comparability in reimbursement decisions. The objective was to analyze the health economic impacts of novel 2 L interventions and conventional immunochemotherapies (bendamustine-rituximab [BR], rituximab-gemcitabine-oxaliplatin [R-GemOx]) from a German healthcare payer's perspective as a function of treatment duration. METHODS: An economic model was developed to compare treatment costs of 2 L interventions depending on the treatment duration. Treatment duration was measured by progression-free survival (PFS), identified based on a systematic review. Total and average costs were calculated over 5 years to evaluate incremental costs at median PFS for each intervention. RESULTS: Average costs per month at median PFS ranged from €2846 (95% CI: 5067-1641) to €40 535 (95% CI: 91180-N/A) for BR and liso-cel, respectively. Incremental costs at the lowest median PFS (R-GemOx: 5.3 months) revealed -€664, €5560, €11 817, €53 145, and €67 745 for BR, Tafa-L, pola-BR, axi-cel, and liso-cel as compared to R-GemOx, respectively. CONCLUSIONS: Analyses uncovered a variation of incremental costs of 2 L transplant-ineligible DLBCL interventions as a function of time leading to amortization of high-priced interventions.

Cost-benefit evaluation of advanced therapy lines in metastatic triple-negative breast cancer in Germany.

BACKGROUND: Triple-negative breast cancer (TNBC) is responsible for 10-20% cases of breast cancer and is resulting in rising healthcare costs. Thus, health-economic evaluations are needed to relate clinical outcomes and costs of treatment options and to provide recommendations of action from a health-economic perspective. METHODS: We investigated the cost-benefit-ratio of approved treatment options in metastatic TNBC in Germany by applying the efficiency frontier approach. These included sacituzumab-govitecan (SG), eribulin, vinorelbine, and capecitabine. Clinical benefit was measured as (i) median overall survival (mOS) and (ii) health-related quality of life (HRQoL) in terms of time to symptom worsening (TSW). To assess medical benefits, literature was systematically reviewed in PubMed for (i) and (ii), respectively. Treatment costs were calculated considering annual direct outpatient treatment costs from a statutory healthcare payer perspective. It was intended that both, (i) and (ii), yield an efficiency frontier. RESULTS: Annual direct outpatient treatment costs amounted to EUR 176,415.21 (SG), EUR 47,414.14 (eribulin), EUR 13,711.35 (vinorelbine), and EUR 3,718.84 (capecitabine). Systematic literature review of (i) and statistical analysis resulted in OS values of 14.3, 9.56, 9.44, and 7.46 months, respectively. Capecitabine, vinorelbine, and SG are part of the efficiency frontier including OS. The highest additional benefit per additional cost was determined for vinorelbine, followed by SG. Systematic review of (ii) revealed that no TSW data of TNBC patients receiving vinorelbine were available, preventing the presentation of an efficiency frontier including HRQoL. CONCLUSIONS: Vinorelbine is most cost-effective, followed by SG. Health-economic evaluations support decision-makers to assess treatment options within one indication area. In Germany, the efficiency frontier can provide decision support for the pricing of innovative interventions. Results of our analysis may thus guide reimbursement determination.

Cost-effectiveness analysis of transplant-ineligible relapsed or refractory diffuse large B-cell lymphoma treatment options-Experience of the efficiency frontier approach.

OBJECTIVES: The treatment of relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) changed remarkably since the European Medicines Agency-approved chimeric antigen receptor T-cell (CAR-T) therapies (axicabtagene ciloleucel [axi-cel], lisocabtagene maraleucel [liso-cel], tisagenlecleucel [tisa-cel]) for the third-line onwards (3+L), and targeted therapies (polatuzumab vedotin-bendamustine-rituximab [pola-BR], tafasitamab-lenalidomide [Tafa-L]) for the second-line (2L) onwards. As associated rising treatment costs represent an economic burden, the cost-effectiveness of transplant-ineligible R/R DLBCL interventions was assessed from a German healthcare payer's perspective, using the efficiency frontier (EF) approach. METHODS: A systematic literature review was performed to determine the clinical benefit concerning median overall survival (OS) of bendamustine-rituximab (BR), rituximab-gemcitabine-oxaliplatin (R-GemOx), axi-cel, liso-cel, tisa-cel, pola-BR, and Tafa-L. First-year treatment costs (drug and medical services costs) were calculated. Results were merged on two-dimensional graphs illustrating 2L and 3+L EFs. RESULTS: Second-line EF is formed by BR (median OS 11.49 months, €23 958) and Tafa-L (45.7, €104 541), 3+L EF is formed by R-GemOx (12.0, €29 080), Tafa-L (15.5, €104 541), and axi-cel (18.69, €308 516). These interventions build the respective cost-effectiveness thresholds for novel interventions. CONCLUSIONS: Using the EF approach, the currently most cost-effective interventions (based on cost-effectiveness ratios) in the indication of R/R DLBCL were identified to guide international reimbursement decisions.

Health economic analysis of patients treated with isavuconazole in a German comprehensive cancer centre.

BACKGROUND: Invasive fungal diseases (IFD) are life-threatening and demand timely and appropriate treatment. Research showed that isavuconazole treatment positively affects clinical outcome and length of hospital stay (LOS). OBJECTIVES: The aim of this study was to assess the hospital costs of patients diagnosed with IFD and treated with isavuconazole using real-world data from a German cancer centre. PATIENTS/METHODS: Data and LOS collected from Jan-2016 to Jun-2021 at Department I of Internal Medicine, University Hospital Cologne were retrieved. Case-related resources consumed during the hospital stay across isavuconazole routes of administration (oral, parenteral, and mixed administration) were identified, quantified, valued and compared via a cost analysis that adopted the healthcare payer perspective. RESULTS: In total, 101 cases with isavuconazole treatment were identified (oral: n = 22, 21.8%; parenteral: n = 59, 58.4%; mixed: n = 20, 19.8%). Median total LOS was greater in the mixed group (46.5 days; p = .009). Median ICU LOS and ventilation duration were both longest in the parenteral-only group (16 days, p = .008; 224 h, p = .003). Invasive aspergillosis was the most frequent isavuconazole indication (n = 86, 85.2%). Average hospital costs were highest in the mixed group (€ 101,226). The median overall costs of cases treated with isavuconazole was € 52,050. CONCLUSIONS: Treating IFD is resource intensive, often requires intensive care and implies high rates of in-hospital mortality. Our study emphasises the high hospital treatment costs and thus the need for reimbursement systems to enable live-saving costly treatments.

Retrospective modelling of hospital bed capacities associated with the administration of remdesivir during the first wave of COVID-19 in a German metropolitan city.

OBJECTIVES: Internationally, healthcare systems are confronted by an ever-increasing scarcity of medical resources due to the ongoing novel coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to investigate the impact of remdesivir on the demand of hospital bed capacities for hospitalized COVID-19 patients and to evaluate the potentially created capacities for treating additional COVID-19 patients or elective treatments at the hospital. METHODS: An epidemiological model was developed that utilized the population of Cologne (Germany) during the first COVID-19 wave (first hospitalized patient-30 September 2020) to compare two scenarios: no administration of remdesivir (A) and the administration of remdesivir according to the EMA label (B). The results of the Adaptive COVID-19 Treatment Trial were used to evaluate the potential impact of remdesivir on hospital capacity. RESULTS: With the first recorded patient on 2 March 2020, a total of 576 COVID-19 hospitalized patients were detected during the first wave in Cologne. Comparing both scenarios (A versus B) of the model, the administration of remdesivir increased the number of discharges from 259 to 293 (+5.8%) and fewer patients needed ICU admission [214 versus 178 (-6.3%)]. In addition, the model estimated 20 fewer deaths (scenario B). Based on a reduced length of stay, 31.4 hospital beds (57.0 versus 25.6) could have been freed by administering remdesivir to eligible patients. This would have allowed either the treatment of an additional 730 COVID-19 patients or 660 elective treatments. CONCLUSIONS: In our model, remdesivir administration profoundly contributed to free hospital capacities in the metropolitan city Cologne in Germany.

A cost of illness study of COVID-19 patients and retrospective modelling of potential cost savings when administering remdesivir during the pandemic "first wave" in a German tertiary care hospital.

PURPOSE: First detected in China in 2019, the novel coronavirus disease (COVID-19) has rapidly spread globally. Since then, healthcare systems are exposed to major challenges due to scarce personnel and financial resources. Therefore, this analysis intended to examine treatment costs of COVID-19 inpatients in a German single centre during the first pandemic wave in 2020 from a healthcare payer perspective. Potential cost savings were assessed considering the administration of remdesivir according to the European Medicines Agency label. METHODS: A retrospective medical-chart review was conducted on COVID-19 patients treated at University Hospital Cologne, Germany. Patients were clustered according to an eight-category ordinal scale reflecting different levels of supplemental oxygen. Potential cost savings due to the administration of remdesivir were retrospectively modelled based on a reduced length of stay, as shown in the Adaptive COVID-19 Treatment Trial. RESULTS: 105 COVID-19 patients were identified. There was wide variability in the service data with median treatment costs from EUR 900 to EUR 53,000 per patient, depending on major diagnosis categories and clinical severity. No supplemental oxygen was needed in 40 patients (38.1%). Forty-three (41.0%) patients were treated in intensive-care units, and 30 (69.8%) received invasive ventilation. In our model, in-label administration of remdesivir would have resulted in costs savings of EUR 2100 per COVID-19 inpatient (excluding acquisition costs). CONCLUSION: We found that COVID-19 inpatients suffer from heterogeneous disease patterns with a variety of incurred G-DRG tariffs and treatment costs. Theoretically shown in the model, financial resources can be saved by the administration of remdesivir in eligible inpatients.

Health economic analysis of third-line interventions in diffuse large B-cell lymphomas in Germany: applying the efficiency frontier.

BACKGROUND: In the past decades, highly innovative treatments in the field of diffuse large B-cell lymphoma (DLBCL) became available in clinical practice. The aim of this study was to assess the cost-benefit relation of third-line interventions in DLBCL from a German payer perspective. METHODS: Clinical benefit of allogeneic stem cell transplantation (alloSCT), chimeric antigen receptor T cells therapy (CAR T) [tisagenlecleucel (tisa-cel) and axicabtagene ciloleucel (axi-cel)] and best supportive care (BSC) was assessed in terms of median overall survival (median OS) derived from a systematic literature review in PubMed. Real-world treatment costs were retrieved from the university hospitals Cologne and Hamburg-Eppendorf. The cost-benefit relation was analysed using the efficiency frontier concept. RESULTS: Median OS varied from 6.3 months in BSC to 23.5 months in CAR T (axi-cel), while median real-world treatment costs ranged likewise widely from €26,918 in BSC to €340,458 in CAR T (axi-cel). Shown by the efficiency frontier, alloSCT and axi-cel were found as most efficient interventions. CONCLUSION: The efficiency frontier supports the pricing of innovative therapies, such as third-line interventions in DLBCL, in relation to appropriate comparators. Yet, studies with longer follow-up periods are needed to include studies with unreached median OS and to reflect experiences gained with CAR T in clinical practice.

Principal-agent theory-based cost and reimbursement structures of isavuconazole treatment in German hospitals.

BACKGROUND: Isavuconazole (ISA) is a frequently used antifungal agent for the treatment of invasive fungal diseases (IFDs). However, hospital reimbursement data for ISA is limited. OBJECTIVES: The primary objective of this study was to analyse the different perspectives of relevant stakeholders and the (dis)incentives for the administration of ISA in Germany. To that aim, the health economic effects of using ISA from a hospital management perspective were analysed. PATIENTS/METHODS: Based on principal-agent theory (PAT), the perspectives of (a) the patient (principal) as well as (b) physicians, (c) pharmacists and iv. hospital managers (all agents) were analysed. For the evaluation of the cost-containment and reimbursement strategies of ISA, the German diagnosis-related group (G-DRG) system was used. RESULTS: Hospitals individually negotiating additional payments for innovative treatment procedures (zusatzentgelte [ZE]) within the G-DRG system is a key element of hospital management for the reduction of total healthcare expenditure. Our analysis demonstrated the beneficial role of ISA in healthcare resource utilisation, primarily due to a shortened overall length of hospital stay. Depending on underlying disease, coded G-DRG and ISA formulation, large differences in total reimbursement and the amount of ZE was shown. The PAT demonstrated disincentives for hospital managers to use innovative drugs. CONCLUSIONS: Based on the PAT, beneficial, detrimental and indifferent perspectives of different stakeholders regarding the usage of ISA were shown. A reduction of bureaucratic hurdles is needed in Germany for the extension of effective and innovative antifungal treatment strategies with ISA.

Reimbursement of innovative pharmaceuticals in English and Spanish hospitals-The example of isavuconazole.

BACKGROUND: Kron et al (Mycoses, 64, 2021, 86) found cost savings for the use of the innovative pharmaceutical isavuconazole in the inpatient setting in Germany (Bismarck-based healthcare system). Little is known about the reimbursement of innovative pharmaceuticals in the inpatient setting of Beveridge-based healthcare systems. OBJECTIVES: The aim of this study was to evaluate the market access process and reimbursement of isavuconazole, exemplary for innovative pharmaceuticals, in England and Spain. PATIENTS/METHODS: Market access processes of both countries were described. Focussing on typical patient clusters for isavuconazole treatment, reimbursement data regarding inpatients with (i) allogeneic haematopoietic stem cell transplantation or (ii) acute myeloid leukaemia was considered. Data were publicly available and of high topicality (England 2020/2021, Spain 2018). Discounting and a currency conversion to Euro were applied. RESULTS: This study showed that market access processes of both countries are broadly similar. Further, full reimbursement of isavuconazole as an innovative pharmaceutical may lead to reduction in resource utilisation. Without medication costs, isavuconazole can thus result in cost savings for both patient clusters due to a reduction in length of stay. CONCLUSIONS: Expenses for innovative pharmaceuticals may be balanced or even lead to cost savings due to a reduction in length of stay. The latter contributes to a greater patient benefit. For both healthcare system, the analyses highlighted drugs' cost-effectiveness and assessing its added value into reimbursement decisions is highly relevant.

A budget impact analysis of bezlotoxumab versus standard of care antibiotics only in patients at high risk of CDI recurrence from a hospital management perspective in Germany.

BACKGROUND: Clostridioides difficile infection (CDI) is one of the leading nosocomial infections, resulting in increased hospital length of stay and additional treatment costs. Bezlotoxumab, the first monoclonal antibody against CDI, has an 1 A guideline recommendation for prevention of CDI, after randomized clinical trials demonstrated its superior efficacy vs. placebo. METHODS: The budget impact analysis at hand is focused on patients at high risk of CDI recurrence. Treatment with standard of care (SoC) + bezlotoxumab was compared with current SoC alone in the 10 most associated Diagnosis Related Groups to identify, analyze, and evaluate potential cost savings per case from the German hospital management perspective. Based on variation in days to rehospitalization, three different case consolidation scenarios were assessed: no case consolidation, case consolidation for the SoC + bezlotoxumab treatment arm only, and case consolidation for both treatment arms. RESULTS: On average, the budget impact amounted to € 508.56 [range: € 424.85 - € 642.19] for no case consolidation, € 470.50 [range: € 378.75 - € 601.77] for case consolidation in the SoC + bezlotoxumab treatment arm, and € 618.00 [range: € 557.40 - € 758.41] for case consolidation in both treatment arms. CONCLUSIONS: The study demonstrated administration of SoC + bezlotoxumab in patients at high risk of CDI recurrence is cost-saving from a hospital management perspective. Reduced length of stay in bezlotoxumab treated patients creates free spatial and personnel capacities for the treating hospital. Yet, a requirement for hospitals to administer bezlotoxumab is the previously made request for additional fees and a successful price negotiation.

Quantifying guideline adherence in mucormycosis management using the EQUAL score.

OBJECTIVES: Mucormycosis is a difficult-to-diagnose life-threatening disease with high morbidity and mortality. Adherence to guidelines that lead through complex management and support clinical decisions is however rarely reported. By applying the EQUAL Score, our study evaluates the management of mucormycosis at the University Hospital of Cologne, Germany. METHODS: We performed a retrospective chart review of patients with mucormycosis at the University Hospital of Cologne. Data collection comprised items for quality assessment in mucormycosis management according to the EQUAL Mucormycosis Score and economics. RESULTS: Of 29 patients identified, 27 were documented retrospectively. Eight patients of 18 with neutropenia (>10 days) or receiving allogeneic stem cell transplantation (44.4%) received mould active prophylaxis. Chest CT was done in 21 patients (77.8%), while BAL and direct microscopy of BAL fluid was performed in 22 patients (81.5%), culture in 22 (81.5%) and fungal PCR in 24 (88.9%). First-line treatment was liposomal amphotericin B in 19 patients (70.4%). Isavuconazole or posaconazole with therapeutic drug monitoring was used in four (14.8%) and in one patient (3.7%), respectively. In our cohort, crude mortality was 51.9% (n = 14) with a median survival time of 113 days. During the management of the 27 patients, 450 points (53.8%) of the maximum EQUAL Mucormycosis Score were achieved (median 15 points, range 6-30). CONCLUSIONS: We observed management of mucormycosis aligning with current guidelines and hope to encourage other groups to use the EQUAL Score in routine clinical settings. Future studies will evaluate whether guideline adherence in mucormycosis management improves patient outcome.

Infectious disease services: a survey from four university hospitals in Germany.

PURPOSE: Involvement of infectious disease (ID) specialists in the care of hospitalized patients with infections through consultation services improves the quality of care and the outcome of patients. This survey aimed to describe activities and utilization of ID consultations at four German tertiary care hospitals. METHODS: A 1-month (March 2016) retrospective cross-sectional study at four university hospitals (Freiburg, Jena, Cologne and Regensburg) was performed. Only ID consultations with written documentation and bedside patient evaluation were included. Consultations were analyzed with regard to requesting departments, infections, case severity, and diagnostic and therapeutic recommendations. RESULTS: In the study period, 638 ID consultations were performed in 479 patients-corresponding to 3-4 consultations per 100 inpatient cases. Patients were characterized by a high disease complexity-the mean case mix index in patients with consultation was 10.1 compared to 1.6 for all patients. ID consultations were requested by many different specialties, with approximately half of the requests coming from surgical disciplines. ID consultations resulted in revised diagnoses in 34% of the cases, provided recommendations for additional diagnostic procedures in 66%, and for modifications of antimicrobial regimens in 70% of the cases. CONCLUSIONS: Infectious disease consultations were requested for patients with severe and complicated diseases and resulted in recommendations that highly impacted the diagnostic work-up and therapeutic management of patients. The results of this survey may help to estimate requirements for establishment of such services in Germany.

Economic evaluation of chronic lymphocytic leukemia from a hospital management perspective.

OBJECTIVES: Treatment of chronic lymphocytic leukemia (CLL) is currently undergoing dramatic changes. We analyzed economic risks in hospitalized patients with CLL from a management perspective. METHODS: One hundred and twelve patients with CLL hospitalized in 2013 and 2014 at the University Hospital of Cologne were analyzed. To assess profit margins (PMs) per case, diagnosis-related group (DRG) reimbursement data were merged with an internal cost accounting scheme depending on age, prognostic factors, and DRG key performance indicators. RESULTS: In 112 patients, 284 cases coded by 19 different DRG with strongly fluctuating cost revenue ratios were found with an overall negative PM of €137 147. The DRG R61H was identified as the one most commonly coded (174 cases, 61.3%) with a deficit per case of €814. Subanalysis demonstrated that the payments were not cost covering due to excessive length of stay and staff costs. Significant differences in PM per case concerning age, length of stay and number of operation and procedure key (OPS) codes (P < 0.05) were found. CONCLUSION: In our research-driven tertiary care hospital, inpatient treatment of patients with CLL is not cost covering. This analysis demonstrates the need for novel care/reimbursement structures in CLL. From a hospital management perspective, cost revenue controlling is crucial to avoid major economic risks.

A cost and resource utilization analysis of micafungin bridging for hemato-oncological high-risk patients undergoing allogeneic stem cell transplantation.

BACKGROUND: Intravenous bridging strategies increase exposure of antifungal prophylaxis in high-risk hematological patients. The cost-effectiveness of such strategies has not been analyzed. METHODS: A recent study compared the impact of oral posaconazole (POS) and oral posaconazole with intravenous micafungin bridging (POS-MIC) as prophylactic antifungal regimens in patients undergoing allogeneic stem cell transplantation (aSCT). Based on data from the Cologne Cohort of Neutropenic Patients (CoCoNut), a health economic evaluation of direct treatment costs was performed to analyze the economic impact of micafungin bridging. Analysis was undertaken based on current guidelines for the German societal perspective with an annual discount rate of 5%, whereby indirect costs were disregarded due to the severity of the underlying disease. Sensitivity analysis of cost calculation with different discount rates was performed to improve robustness of our health economic evaluation. RESULTS: A retrospective case-control analysis of patients undergoing aSCT between 05/2006 and 07/2011 was performed; 106 patients each in the POS and POS-MIC group were included. In the POS and POS-MIC group, mean costs per patient for the treatment on bone marrow transplant ward were €27,228 (95% CI: €24,932-€29,525) vs. €27,894 (95% CI: €26,414-€29,375; P = 0.629), for diagnostic measures €2124 (95% CI: €1823-€2425) vs. €1269 (95% CI: €1168-€1370; P ≤ 0.001), for laboratory findings €10,612 (95% CI: €9681-€11,544) vs. €8836 (95% CI: €8198-€9475; P = 0.002), and for overall antifungal treatment €6105 (95% CI: €4703-€7508) vs. €6943 (95% CI: €5393-€8493; P = 0.428), resulting in mean overall costs per patient of €60,304 (95% CI: €53,969-€66,639) vs. €58,089 (95% CI: €51,736-64,442; P = 0.625). CONCLUSIONS: Our health economic evaluation shows micafungin bridging in aSCT patients did not result in excess cost. Higher acquisition costs of antifungal prophylaxis were balanced by a reduced incidence of possible IFD and lower costs for empirical, preemptive, and targeted antifungal therapy as well as lower costs for diagnostic measures and laboratory tests in the micafungin bridging group.

Economic effects of treating postpartum hemorrhage with vacuum-induced hemorrhage control devices - A budget impact analysis of the Jada® System in the German obstetrics setting.

OBJECTIVE: This study aimed to assess the budget impact of vacuum-induced hemorrhage control (VHC) devices for treating postpartum hemorrhage (PPH) from the perspective of the German statutory health insurance (SHI). STUDY DESIGN: Evidence shows that treating PPH with VHC instead of uterine balloon tamponade (UBT) can reduce resource consumption (e.g., reduced number of blood transfusions and length of stay). A budget impact model combining aggregated German real-world reimbursement data of PPH cases with the assumption of resource reduction due to VHC usage was developed. Diagnosis-related groups (DRG) of PPH cases and their frequencies were collected using a publicly available database. A "downgrading mechanism" was performed, leading to a less resource-intensive DRG, i.e., resulting in a lower flat fee to be paid by SHI. Four subgroups were differentiated based on coded diagnoses and procedures: 1) PPH (O72.-) as main diagnosis, 2) PPH as secondary diagnosis, 3) UBT procedure coded, and 4) UBT or standard tamponade coded. Weighted averages of cost savings per case were calculated. RESULTS: Data from 7,129 (subgroup 1), 49,523 (subgroup 2), 1,668 (subgroup 3), and 3,406 (subgroup 4) cases were retrieved. After applying the downgrading mechanism, cost savings (weighted average) resulted in 184.09 €, 210.50 €, 921.33 €, and 633.74 € for subgroups 1-4, respectively, CONCLUSION: This is the first German budget impact analysis of VHC for the treatment of PPH. Results showed the highest cost-saving potential for cases currently treated with UBT. Demonstrating not only clinical but also financial consequences of innovative treatments is crucial for the adoption into clinical practice.

A Retrospective Budget Impact Analysis of Fidaxomicin Treatment for Clostridioides difficile Infections (CDI) in Germany.

BACKGROUND: Clostridioides difficile is the most common cause of healthcare-associated diarrhea. Research suggests that treating C. difficile infections (CDI) with fidaxomicin (FDX) is more effective than vancomycin (VAN), with potential cost savings. The objective was to calculate the budget impact of FDX treatment compared to VAN from a German payer perspective. RESEARCH DESIGN AND METHODS: The analysis used real-world data of patients discharged from University Hospital Cologne between Jan-01-2018 and Dec-31-2019. We identified recurrent and non-recurrent CDI cases and calculated direct treatment costs based on G-DRG flat rates. To calculate average costs per treatment and the budget impact, recurrence probabilities for VAN and FDX were taken from published evidence (28-day and 90-day scenarios). RESULTS: Totally, 475 cases were analyzed, thereof 421 non-recurrent, causing mean costs of €32,901 per case (95% CI: 27.752-38.050). Thirty-two patients experienced a recurrence within 28 days, yielding mean costs of €10,952 (95% CI: 5.627-16.277) for their additional hospital stay. The resulting budget impact was €1,303 (95% CI: 670 - 1.937) in favor of FDX, ranging from €148.34 to €2,190.30 in scenario analyses. CONCLUSION: The analysis indicates FDX treatment can lead to cost savings compared to VAN. Future research should focus on specific patient groups, such as refractory CDI patients.

Attributable mortality of candidemia - Results from the ECMM Candida III multinational European Observational Cohort Study.

INTRODUCTION: Despite antifungal advancements, candidaemia still has a high mortality rate of up to 40%. The ECMM Candida III study in Europe investigated the changing epidemiology and outcomes of candidaemia for better understanding and management of these infections. METHODS: In this observational cohort study, participating hospitals enrolled the first ten consecutive adults with blood culture-proven candidemia. Collected data included patient demographics, risk factors, hospital stay duration (follow-up of 90 days), diagnostic procedures, causative Candida spp., management details, and outcome. Controls were included in a 1:1 fashion from the same hospitals. The matching process ensured similarity in age (10-year range), primary underlying disease, hospitalization in intensive care versus non-ICU ward, and major surgery within 2 weeks before candidemia between cases and controls. Overall and attributable mortality were described and a survival probability for cases and controls was performed. RESULTS: One hundred seventy-one pairs consisting of patients with candidemia and matched controls from 28 institutions were included. In those with candidemia, overall mortality was 40.4%. Attributable mortality was 18.1% overall but differed between causative Candida species (7.7% for Candida albicans, 23.7% for Candida glabrata/Nakaseomyces glabratus, 7.7% for Candida parapsilosis and 63.6% for Candida tropicalis). Regarding risk factors, presence of a central venous catheter, total parenteral nutrition and acute or chronic renal disease were significantly more common in cases versus controls. Duration of hospitalization, and especially that of ICU stay was significantly longer in candidemia cases (20 (IQR 10-33) vs 15 days (IQR 7-28); p=0.004). CONCLUSIONS: Although overall and attributable mortality in this subgroup analysis of matched case/control pairs remains high, the attributable mortality appears to have decreased in comparison to historical cohorts. This decrease may be driven by improved prognosis of Candida albicans and Candida parapsilosis candidemia; whereas candidemia due to other Candida spp. exhibits a much higher attributable mortality.

Health-economic modelling of cost savings due to the use of rezafungin based on a German cost-of-illness study of candidiasis.

Objective: Candida species are responsible for fungal diseases and the development of nosocomial bloodstream infections. Treatment is resource-intensive and economically challenging for healthcare systems. Cost analyses of drugs against candidiasis, such as rezafungin, are thus of great interest to healthcare payers. Methods: We conducted a cost-of-illness study of patients with Candida infections based on real-word data of the Department I of Internal Medicine, University Hospital Cologne (Germany) between 2016 and 2021. Health-economic parameters were analysed to describe the economic impact of Candida infections. Potential cost savings due to the administration of rezafungin were modelled for patients with invasive candidiasis or candidaemia based on a 5 day reduction of ICU length of stay (LOS) shown by the STRIVE study. Results: We found 724 cases (652 patients) with Candida infections, of which 61% received ICU treatment (n = 442) and 29% were mechanically ventilated (n = 207). Twenty-six percent died during hospitalization (n = 185). Median LOS was 25 and 15 days, on normal wards and ICU, respectively. Median total treatment costs per case accounted for €22 820. Based on the ICU LOS reduction, the retrospective model showed a median cost-saving potential of €7175 per hospital case with invasive candidiasis or candidaemia. Accumulated cost savings for 37 patients of €283 335 were found. Conclusions: Treatment of candidiasis is cost intensive due to increased hospital LOS. The ICU LOS reduction rezafungin showed in STRIVE would lead to sustainable cost savings.

Cost Comparison of Treatment Alternatives for Pleural Effusion and Ascites from a Payer Perspective: Are There Cost Savings from Indwelling Catheters?

Background: The presence of pleural effusions and ascites in patients is often considered a marker of illness severity and a poor prognostic indicator. This study aims to compare inpatient and outpatient costs of alternative invasive treatments for ascites and pleural effusions. Methods: The retrospective single-institution study included inpatient cases treated for pleural effusion (J90 and J91) or ascites (R18) at the University Hospital Cologne (UHC) in Germany between January 01, 2020, and December 31, 2021. Costs for punctures and indwelling catheter systems (ICSs) as well as pleurodesis were analyzed in different comparator treatment pathways. Real-world data from the UHC tertiary care center were based on diagnosis-related group fees from 2020 to 2021. A simulation of outpatient expenses was carried out to compare inpatient and outpatient costs for each pathway from a payer perspective. Results: A total of 4323 cases (3396 pleural effusions and 1302 ascites) were analyzed. For ascites, inpatient implantation with home care drainage was found to be the most expensive option, with total costs of €1,918.58 per procedure, whereas outpatient puncture was the least expensive option at €60.02. For pleural effusions, the most expensive treatment pathway was pleurodesis at €8,867.84 compared with the least costly option of outpatient puncture resulting in total costs per procedure of €70.03. A break-even analysis showed that outpatient puncture remains the most inexpensive treatment option, and the ICS comprises a cost-saving potential. Longevity of several months with the use of ICSs results in both enhanced quality of life for patients and increased cost savings.

Health Economic Aspects of Platelet Concentrates: Comparing Cost and Reimbursement of Pathogen Inactivated and Conventional Platelet Concentrates in a German Comprehensive Cancer Center.

INTRODUCTION: Pathogen inactivation (PI) utilizing amotosalen and UVA light (INTERCEPT® Blood System) is a well-established method for the production of safer platelet concentrates (PCs). While many studies describe clinical and logistical benefits of PI, the implications and potential challenges from a hospital management perspective have not yet been analyzed - health economic analyses considering reimbursement of PI are lacking. The objective of this analysis was to examine the real-life inpatient treatment costs from a hospital perspective and to assess the economic impact of PI-PC versus conventional PC (CONV-PC) administration in Germany. METHODS: Real-life cost data for inpatient cancer cases from 2020 of the University Hospital Cologne were identified by operating and procedure codes. The German diagnosis-related groups, extra fees, case mix index (CMI), length of stay (LOS), and average resource consumption of PC were evaluated from a micro-management perspective. The potential economic impact of implementing PI-treated PCs was modeled retrospectively. RESULTS: In total, 951 inpatient cases were analyzed (CMI [median 4.7-9.9], LOS [median 26 days], number of cases in intensive care units [38%]). The median DRG fee was between EUR 13,800 and EUR 26,400. According to our model, the use of PI-PC compared to CONV-PC would result in savings between EUR 184 and EUR 306 per case. CONCLUSION: From a hospital management perspective, oncological cases requiring PC transfusion are associated with a high CMI (reimbursement per DRG flat fee) and moderate costs with sufficient add-on payment for PI on a case level. Investment and process costs for PI implementation can be analyzed for site-specific scenarios.
