Blood Product Supply in Germany: The Impact of Apheresis and Pooled Platelet Concentrates.

BACKGROUND: In Germany, about 60% of all produced platelet concentrates (PCs) are apheresis PCs (APCs). Ongoing discussions on APC reimbursement and costs might lead to a potential shift in pooled PC (PPC)/APC production. Objective of this analysis was to build a comprehensive model from the societal perspective to evaluate consequences associated with shifts in platelet supply and demand. METHODS: Literature search, desktop researches on platelet supply and demand. Model calculations, time horizon one year: model input from the Paul-Ehrlich-Institute, data 2013. Base case: 19.2% of annual whole blood donations (WBDs) were used for production of 38.5% PPCs, decay of 46,218 PCs (8.0%). Scenarios calculated: variation in PPC proportion of 10-100%. RESULTS: Base case: during PPC production 41,957-83,913 red blood cell concentrates (RBCCs) are estimated to be lost, which corresponds to 1-2% of annual RBCCs in Germany. Scenarios were calculated for a production of 60-100% PPCs: loss is estimated to be 1.5-5.0% of annual RBCCs (65,430-218,099), decay 54,189-69,022 PCs (9.4-12.0%). CONCLUSION: Production of different blood components is interlinked and sensitive to unidimensional decisions. Increasing PPC proportion has negative impact on the RBCC production and on the antigen-matched APC donor pool. Completion of the model calculations to predict the optimal PPC/APC proportion would require evidence on the number of refractory patients, donor pool sizes, and incidences of diseases requiring platelet transfusions.

Economic and clinical aspects of intravenous versus oral busulfan in adult patients for conditioning prior to HSCT.

PURPOSE: Busulfan (BU) used as cytoreductive conditioning prior to hematopoietic stem cell transplantation (HSCT) is available as intravenous (IV) and oral (O) preparation. IV-BU has clinical advantages associated with relevant incremental costs. The aim was to determine the economic impact of IV-BU versus O-BU in adult HSCT recipients from a German health care providers' perspective. METHODS: A budget-impact model (BIM) including costs and risks for oral mucositis (OM), infection with OM, and hepatic sinusoidal obstruction syndrome (SOS) was developed. Model inputs are literature data comparing clinical effects of IV-BU versus O-BU and German cost data (conditioning therapy, treatment of OM, infections, SOS without/with multiorgan failure) from literature and tariff lists. RESULTS: Base case calculations resulted the following: total costs of adverse events were €86,434 with O-BU and €44,376 with IV-BU for ten patients each. Considering costs of adverse events and drugs, about €5840 for ten patients receiving IV-BU are saved. Sensitivity analyses were conducted in several ways. Cost savings range between €4910 and €12,640 per ten patients for all adverse events and €2070 or €1140 per ten patients considering SOS only. Drug treatment of SOS and treatment of multiorgan failure during severe SOS are major cost drivers. Worst case scenario calculations (assuming -25% risk of all adverse events for O-BU and +25% for IV-BU) yield up to €27,570 per ten patients with IV-BU. CONCLUSIONS: Considering costs of adverse events and drugs, IV-BU is the dominant alternative from a German providers' perspective. For more comprehensive economic evaluations, additional epidemiological data, evidence on clinical outcomes, patient-reported outcomes, and treatment patterns are needed.

Model calculations to quantify clinical and economic effects of pathogen inactivation in platelet concentrates.

BACKGROUND: Future shortages in platelet supply are expected in Germany due to demographic changes. A rising cancer incidence will lead to an increasing demand for platelet concentrates (PCs) while the number of potential donors will decrease. Pathogen inactivation (PI) aims to inactivate various infectious agents including emerging pathogens to extend the shelf-life of PCs and reduce the frequency of acute transfusion reactions (ATRs). In this context, the clinical and economic impact of PI on platelet transfusion was evaluated. MATERIAL AND METHODS: Model calculations were conducted for 2 scenarios considering different production settings. Frequencies of ATRs were based on literature analyses, platelet and ATR costs on cost analyses. RESULTS: The estimated average costs for ATRs of grade 1 and 2, irrespective of origin, and grade 3 (allergic) were € 104, € 238, and € 1,200, respectively. Approximately 400 PC-related ATRs per 10(5) transfusions can be avoided, with estimated savings amounting to € 77,000. The total cost increase was calculated to approximately € 30-50 per PI-treated PC. CONCLUSION: PI potentially saves plasma, prolongs shelf-life, decreases donor deferral, and reduces ATRs. Model calculations considering clinical and safety benefits of PI show a rational cost increase. The impact of PI should be further evaluated from a societal perspective regarding future blood supply and infectious disease globalization.

A retrospective observational single-centre study on the burden of immune thrombocytopenia (ITP).

BACKGROUND: German data on economic consequences of immune thrombocytopenia (ITP) are limited. PATIENTS AND METHODS: A retrospective, observational study based on chart review of adult patients with a confirmed diagnosis of ITP was conducted at a German university hospital. Costs are presented from the hospital perspective. RESULTS: Of 50 eligible patients, 45 could be classified by disease duration: 19 patients < 3 months (38%, newly diagnosed ITP), 12 patients ≥ 3 to < 12 months (24%, persistent ITP), 19 patients ≥ 12 months (38%, chronic ITP). Complications included 85 bleeding events in 43 patients, including 3 intracranial haemorrhages. Documented were 955 outpatient visits in 43 patients (86%) and 92 inpatient hospital admissions in 45 patients (90%). Of the 46 patients (92%) treated, all received corticosteroids, 25 (50%) intravenous immunoglobulin, and 7 (14%) further therapies. 12 patients (24%) underwent splenectomy. Average total direct medical costs (mean (standard deviation)) were 17,091 (18,859) per patient, 12,749 (11,663) in 17 newly diagnosed ITP patients with a 0.88-month (0.65 months) average disease duration, and 29,868 (29,397) in 13 chronic ITP patients with a 33.5-month (16.8 months) average disease duration. Inpatient stays were the main cost drivers. CONCLUSION: These data concerning current healthcare provision for ITP patients in Germany indicate considerable resource consumption and the need for more effective treatment options in individual patients.

Burden of Oral Mucositis: A Systematic Review and Implications for Future Research.

BACKGROUND: Surprisingly little is known about the burden of oral mucositis (OM). We provide a systematic review of studies on the burden of OM (incidence, economic impact, health-related quality of life (HRQoL)). METHODS: Systematic literature searches were made in BIOSIS, EMBASE, and MEDLINE. Inclusion criteria were studies on OM in hematology/oncology patients of ≥ 18 years, journal articles, English language, and published between 2000 and 2016; OM treatment studies were excluded. Quality assessment was performed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We screened 4,996 hits, and identified 68 studies of which 13 were without transparency on OM grading. The evidence level of 65 studies was rated 'low' or 'very low' in 58.5%, 'moderate' in 20% and 'high' in 21.5%. Mean value of incidence (7 studies) was 83.5% for all grades of OM with hematopoietic stem cell transplantation. OM incidence for all grades in head and neck cancer patients was 59.4-100%. Considering the economic impact, 16 studies showed highly variable numbers. HRQoL was measured in 16 studies using 13 different instruments. Statistically significant changes in HRQoL scores were demonstrated. CONCLUSION: OM is common, burdensome, costly and imposes major reductions in HRQoL. However, from a quality standpoint, the level of current evidence in OM is disappointing. The field needs continued attention to address methodological challenges.

Wishes and worries of haemophilia patients. A patient survey from Bavaria.

Haemophilia care in Germany has achieved a high level and enables the majority of patients to lead a largely normal life. The Bluter Betreuung Bayern e.V. (BBB) aims to improve health care and support for haemophilia patients. A questionnaire has been developed by BBB representatives to evaluate unmet medical needs from the patient perspective. It was sent to 290 haemophilia patients and/or their parents in Bavaria in November 2015. The response rate was 51.4 %: 66 children aged < 15 years (66.7 % severe), 30 patients 15-24 years (66.7 % severe), 26 patients 25-44 years (80.8 % severe), 24 patients > 44 years (95.8 % severe). Prophylactic therapy in patients with severe haemophilia aged < 25 and ≥ 25 years is given "always" in ≥ 80 % and > 60 %, respectively. Substitution therapy is mostly uncomplicated. Satisfaction with medical care is high. Chronic pain is a problem with increasing age. Patients aged 25-44 years worry least regarding future health, safety and availability of factor products, patients > 44 years most. Overall, 80-100 % of the patients from all age groups are interested in information on the current state of science. Offers of the BBB for psychosocial support in addition to the medical care seem to be helpful and needed in all age groups.
