Hospitalization rates for complications due to systemic therapy in the United States.

The aim of this study was to estimate the trends and burdens associated with systemic therapy-related hospitalizations, using nationally representative data. National Inpatient Sample data from 2005 to 2016 was used to identify systemic therapy-related complications using ICD-9 and ICD-10 external causes-of-injury codes. The primary outcome was hospitalization rates, while secondary outcomes were cost and in-hospital mortality. Overall, there were 443,222,223 hospitalizations during the study period, of which 2,419,722 were due to complications of systemic therapy. The average annual percentage change of these hospitalizations was 8.1%, compared to - 0.5% for general hospitalizations. The three most common causes for hospitalization were anemia (12.8%), neutropenia (10.8%), and sepsis (7.8%). Hospitalization rates had the highest relative increases for sepsis (1.9-fold) and acute kidney injury (1.6-fold), and the highest relative decrease for dehydration (0.21-fold) and fever of unknown origin (0.35-fold). Complications with the highest total charges were anemia ($4.6 billion), neutropenia ($3.0 billion), and sepsis ($2.5 billion). The leading causes of in-hospital mortality associated with systemic therapy were sepsis (15.8%), pneumonia (7.6%), and acute kidney injury (7.0%). Promoting initiatives such as rule OP-35, improving access to and providing coordinated care, developing systems leading to early identification and management of symptoms, and expanding urgent care access, can decrease these hospitalizations and the burden they carry on the healthcare system.

Association between Concomitant Use of Hydrochlorothiazide and Adverse Chemotherapy-Related Events among Older Women with Breast Cancer Treated with Cyclophosphamide.

BACKGROUND: The pharmacy reference database, Micromedex, lists concomitant hydrochlorothiazide and cyclophosphamide use as a potential, major drug-drug interaction (DDI), although only one small, single-center study supports this claim. Our objective was to estimate associations between this potential DDI and two adverse chemotherapy-related events, neutropenia-related hospitalizations and treatment regimen discontinuation, among a cohort of women with breast cancer initiating adjuvant chemotherapy containing cyclophosphamide. METHODS: Using linked Surveillance, Epidemiology, and End Results Program (SEER)-Medicare data, we included women 66 years and older with breast cancer diagnosis between 2007 and 2011, who initiated a regimen containing cyclophosphamide. Risk ratios (RR) and 95% confidence intervals for adverse outcomes comparing women exposed versus unexposed to the potential DDI were assessed using modified multivariable Poisson regression adjusting for potential confounders. RESULTS: In total, 27% of women receiving cyclophosphamide treatment were exposed to concomitant hydrochlorothiazide, of which 11% experienced a neutropenia-related hospitalization and 21% discontinued their chemotherapy regimen prior to completion. Adjusted risks of both adverse events were similar between those exposed and unexposed to the potential DDI [neutropenia-related hospitalization: adjusted RR (aRR) = 0.92 (0.70-1.21); treatment discontinuation: aRR = 1.00 (0.96-1.05)]. CONCLUSIONS: Our results do not support an association between concomitant hydrochlorothiazide use and two clinically relevant adverse chemotherapy-related events. IMPACT: Our results support reassessing and potentially lowering severity of this potential interaction in drug reference databases.

National Trends in Hospitalization for Fever and Neutropenia in Children with Cancer, 2007-2014.

OBJECTIVE: To assess the trends of inpatient resource use and mortality in pediatric hospitalizations for fever with neutropenia in the US from 2007 to 2014. STUDY DESIGN: Using National (Nationwide) Inpatient Sample (NIS) and International Classification of Diseases, Ninth Revision, Clinical Modification codes, we studied pediatric cancer hospitalizations with fever with neutropenia between 2007 and 2014. Using appropriate weights for each NIS discharge, we created national estimates of median cost, length of stay, and in-hospital mortality rates. RESULTS: Between 2007 and 2014, there were 104 315 hospitalizations for pediatric fever with neutropenia. The number of weighted fever with neutropenia hospitalizations increased from 12.9 (2007) to 18.1 (2014) per 100 000 US population. A significant increase in fever with neutropenia hospitalizations trend was seen in the 5- to 14-year age group, male sex, all races, and in Midwest and Western US hospital regions. Overall mortality rate remained low at 0.75%, and the 15- to 19-year age group was at significantly greater risk of mortality (OR 2.23, 95% CI 1.36-3.68, P = .002). Sepsis, pneumonia, meningitis, and mycosis were the comorbidities with greater risk of mortality during fever with neutropenia hospitalizations. Median length of stay (2007: 4 days, 2014: 5 days, P < .001) and cost of hospitalization (2007: $8771, 2014: $11 202, P < .001) also significantly increased during the study period. CONCLUSIONS: Our study provides information regarding inpatient use associated with fever with neutropenia in pediatric hospitalizations. Continued research is needed to develop standardized risk stratification and cost-effective treatment strategies for fever with neutropenia hospitalizations considering increasing costs reported in our study. Future studies also are needed to address the greater observed mortality in adolescents with cancer.

Safety and cost benefit of an ambulatory program for patients with low-risk neutropenic fever at an Australian centre.

BACKGROUND: Neutropenic fever (NF) is a common complication of cancer chemotherapy. Patients at low risk of medical complications from NF can be identified using a validated risk assessment and managed in an outpatient setting. This is a new model of care for Australia. This study described the implementation of a sustainable ambulatory program for NF at a tertiary cancer centre over a 12-month period. METHODS: Peter MacCallum Cancer Centre introduced an ambulatory care program in 2014, which identified low-risk NF patients, promoted early de-escalation to oral antibiotics, and early discharge to a nurse-led ambulatory program. Patients prospectively enrolled in the ambulatory program were compared with a historical-matched cohort of patients from 2011 for analysis. Patient demographics, clinical variables (cancer type, recent chemotherapy, treatment intent, site of presentation) and outcomes were collected and compared. Total cost of inpatient admissions was determined from diagnosis-related group (DRG) codes and applied to both the prospective and historical cohorts to allow comparisons. RESULTS: Twenty-five patients were managed in the first year of this program with a reduction in hospital median length of stay from 4.0 to 1.1 days and admission cost from Australian dollars ($AUD) 8580 to $AUD2360 compared to the historical cohort. Offsetting salary costs, the ambulatory program had a net cost benefit of $AUD 71895. Readmission for fever was infrequent (8.0%), and no deaths were reported. CONCLUSION: Of relevance to hospitals providing cancer care, feasibility, safety, and cost benefits of an ambulatory program for low-risk NF patients have been demonstrated.

Outcomes of previously untreated elderly patients with AML: a propensity score-matched comparison of clofarabine vs. FLAG.

The 5-year overall survival (OS) in patients ≥ 60 years old with acute myeloid leukemia (AML) remains < 10%. Clofarabine-based induction (CLO) provides an alternative to low-intensity therapy (LIT) and palliative care for this population, but supporting data are conflicted. Recently, our institution adopted the FLAG regimen (fludarabine, cytarabine, and granulocyte colony-stimulating factor) based on data reporting similar outcomes to CLO in elderly patients with AML unable to tolerate anthracycline-based induction. We retrospectively analyzed the efficacy and safety of patients ≥ 60 years old with AML treated with FLAG or CLO over the past 10 years. We performed a propensity score match that provided 32 patients in each group. Patients treated with FLAG had a higher CR/CRi rate (65.6 vs. 37.5%, P = 0.045) and OS (7.9 vs. 2.8 months, P = 0.085) compared to CLO. Furthermore, FLAG was better tolerated with significantly less grade 3/4 toxicities and a shorter duration of neutropenia (18.5 vs. 30 days, P = 0.002). Finally, we performed a cost analysis that estimated savings to be $30,000-45,000 per induction with FLAG. Our study supports the use of FLAG both financially and as an effective, well-tolerated high-dose treatment regimen for elderly patients with AML. No cases of cerebellar neurotoxicity occurred.

Molgramostrim para o tratamento da anemia aplástica, mielodisplasia, neutropenias constitucionais, doença pelo HIV e transplante de medula ou pâncreas / Molgramostrim for the treatment of aplastic anemia, myelodysplasia, constitutional neutropenia, HIV disease and transplantation of the marrow or pancreas

O fármaco molgramostim é fator estimulador de colônias de granulócitos e macrófagos (GM-CSF), um importante fator de crescimento hematopoiético e modulador imunológico. Molgramostim também tem efeitos profundos sobre as atividades funcionais de vários leucócitos circulantes1. Seu uso resulta em aumento dose-dependente dos neutrófilos, eosinófilos, macrófagos e, em alguns casos, linfócitos no sangue periférico2. Embora o GM-CSF seja produzido localmente, ele pode atuar de um modo parácrino, recrutando neutrófilos, monócitos e linfócitos circulantes para melhorar as suas funções na defesa do hospedeiro. No Sistema Único de Saúde (SUS) o molgramostim 300 mcg está inserida por meio do Componente Especializado da Assistência Farmacêutica (CEAF) para o tratamento das situações clínicas: anemia aplástica, mielodisplasia, neutropenias constitucionais, doença pelo HIV e transplante de medula ou pâncreas, de acordo com os respectivos Protocolos Clínicos e Diretrizes Terapêuticas (PCDT) e regras do CEAF - Portaria GM/MS nº 1554 de 30 de julho de 2013. O Departamemto de Assistência Farmacêutica e Insumos Estratégicos (DAF/SCTIE) apresentou à CONITEC a proposta de exclusão do fármaco molgramostim 300 mcg injetável (procedimento: 0604250029), fundamentada na inativação e vencimento dos registros do molgramostim, na ausência de comercialização do produto, no desuso do medicamento no CEAF e no pouco uso do fármaco em virtude de um número maior de efeitos adversos. Seguem as argumentações que corroboram a exclusão. Conclui-se que os PCDT que contém o medicamento molgramostim 300 mcg injetável deverão ser atualizados, bem como os procedimentos que regulamentam a dispensação desse medicamento pelo CEAF. Assim, no Protocolo Clínico e Diretrizes Terapêuticas da Anemia Aplástica, Mielodisplasia e Neutropenias Constitucionais (Portaria SAS/MS nº 212, de 10 de abril de 2010) decidiu-se por: a) Exclusão do molgramostim 300 mcg injetável. b) Manutenção do filgrastim 300 mcg injetável.

Feasibility of early discharge strategies for neutropenic fever: outcomes of a Victorian organisational readiness assessment and pilot.

BACKGROUND: Although Australian consensus guidelines support the use of ambulatory care strategies for management of adult patients with low-risk neutropenic fever (NF), few centres have successfully implemented viable programmes. AIMS: To study the feasibility of an early discharge programme for adult patients with low-risk NF and assess organisational factors likely to influence successful implementation across participating Victorian hospitals. METHODS: Four hospitals participated in an organisational readiness assessment preceding selection of a pilot site for programme implementation. Prospective baseline auditing of current practice (i.e. inpatient care until resolution of NF) across three hospitals preceded programme implementation and evaluation. RESULTS: Barriers and facilitators to successful implementation were identified. One hundred and seventeen NF episodes were evaluated during audit phases. The frequency of low-risk NF presentations eligible for early discharge was low (less than two episodes per week). The programme reduced median (interquartile range) duration of parenteral antibiotics and length of stay for eligible patients (n = 11) from 4 (4, 5) days at baseline to 1 (1, 2) day during pilot (P = 0.02) and 4.5 (4, 5) days (baseline) to 2 (1, 3) days (pilot) (P = 0.02) respectively. The proportion of ineligible patients stepped down to oral antibiotics was improved from 38% (baseline) to 67% (pilot). No patients failed ambulatory care requiring readmission into hospital. CONCLUSION: The ambulatory care strategy for management of NF proposed by Australian consensus guidelines has been successfully piloted at a single Victorian centre. Organisational readiness tools can be used to identify potential barriers to the implementation of evidence based practices in patients with NF.

Eliciting patients' preferences for outpatient treatment of febrile neutropenia: a discrete choice experiment.

BACKGROUND: Studies have demonstrated that patients at low risk for febrile neutropenia (FN) complications can be treated safely and effectively at home. Information on patient preferences for outpatient treatment of this condition will help to optimize health care delivery to these patients. The purpose of this study was to elicit non-Hodgkin lymphoma patients' preferences on attributes related to outpatient treatment of FN. METHODS: We used a self-administered discrete choice experiment questionnaire based on the attributes of out-of-pocket costs, unpaid caregiver time required daily, and probability of return to the hospital. Ten paired scenarios in which levels of the attributes were varied were presented to study patients. For each pair, patients indicated the scenario they preferred. Adjusted odds ratios (ORs) of accepting a scenario that described outpatient care for FN were estimated. RESULTS: Eighty-eight patients completed the questionnaire. Adjusted ORs [95 % confidence intervals] of accepting outpatient care for FN were 0.84 [0.75, 0.95] for each $10 increase in out-of-pocket cost; 0.82 [0.68, 0.99] for each 1 h increase in daily unpaid caregiver time; and 0.53 [0.50, 0.57] for each 5 % increase in probability of return to the hospital. CONCLUSIONS: Probability of return to the hospital was the most important attribute to patients when considering home-based care for FN. Patients considered out-of-pocket costs and unpaid caregiver time to be less important than probability of return to the hospital. This study identifies factors that could be incorporated into outpatient delivery systems for FN care to ensure adequate patient uptake and satisfaction with such programs.

Safety and cost-effectiveness of outpatient autologous stem cell transplantation in patients with multiple myeloma.

High-dose chemotherapy with autologous stem cell transplantation (ASCT) remains the standard of care for patients with multiple myeloma. Outpatient ASCT can be an attractive option given wait times and costs associated with inpatient procedures. We initiated an outpatient transplantation protocol in 2006. Patients were treated at a university hospital outpatient clinic that was open 5 days a week. The present study investigated safety and cost-effectiveness of the outpatient program. Ninety-one patients underwent ASCT between 2006 and 2010. The majority of patients (77%) had Durie-Salmon stage III disease; 38% had 1 or more comorbidities. Seventy-six patients (84%) were hospitalized during the first 100 days, mainly for febrile neutropenia (n = 71). Overall survival at day 100 was 100%. No patient was admitted to an intensive care unit. Risk factors for prolonged hospitalization (longer than 7 days) were disease stage IIB or higher and age >60 years. The cost savings was $19,522 (Canadian dollars) per patient compared with inpatient ASCT, for an annual savings of approximately $740,000. In summary, outpatient ASCT performed in a weekday clinic for patients with multiple myeloma appears to be safe and cost-effective, but is associated with a relatively high hospitalization rate.

Health-related quality of life anticipated with different management strategies for febrile neutropenia in adult cancer patients.

PURPOSE: To describe anticipated health-related quality of life (HRQL) for different hypothetical strategies of febrile neutropenia (FN) management in adult cancer patients. METHODS: Seventy-eight adult cancer patients were enrolled. Our study considered four different hypothetical treatment strategies for FN: (1) entire inpatient management with intravenous (IV) antibiotics; (2) oral treatment at home after an initial observation in hospital with IV antibiotics; (3) entire outpatient management with IV antibiotics; and (4) entire outpatient management with oral antibiotics. Initially, patients were asked to rank the different treatment strategies for FN based on their personal preference. Subsequently, HRQL was rated using visual analog scale (VAS), time trade-off (TTO), and willingness-to-pay (WTP). RESULTS: Seventy-five percent of all respondents preferred an outpatient strategy for FN (36% oral, 21% intravenous, 18% early discharge). Further, outpatient strategies were associated with higher mean VAS scores (possible range 0-10) (oral: 6.1 (standard deviation (SD) 3.1); intravenous: 6.2 (SD 2.2); early discharge: 5.7 (SD 2.1)) as compared to inpatient care (5.3 (SD 2.9)). On the aggregate level, patients were willing to give up between 9 and 10 weeks of their life (TTO; corresponding to <1% of remaining life expectancy) and to pay between $255 and $327 Canadian dollars (WTP) to avoid treatment in hospital. CONCLUSIONS: Our study indicates that the majority of adult cancer patients would prefer an outpatient strategy for FN. However, patients' preferences vary substantially at the individual level. Implementation of outpatient strategies into routine clinical practice should consider this variability.

Advances in management of low-risk febrile neutropenia.

PURPOSE OF REVIEW: To describe and discuss the most recent advances in the management of low-risk febrile neutropenia in children with cancer. RECENT FINDINGS: Several risk stratification tools for children with febrile neutropenia have been developed, although none of these tools have been directly compared and few have been validated in independent populations. However, there is good evidence that, for pediatric patients with febrile neutropenia at low risk for severe infection, outpatient management is a well tolerated and efficacious alternative to inpatient care. Moreover, major progress has been made in obtaining and understanding perceived quality of life and preferences for outpatient management in pediatric cancer patients. Many parents prefer inpatient management although child quality of life is, in general, anticipated to be higher with outpatient intravenous therapy. Finally, outpatient strategies are more cost-effective as compared with traditional management in hospital. SUMMARY: Outpatient management is a well tolerated and cost-effective strategy for low-risk febrile neutropenia in children with cancer, although parental preferences are highly variable for outpatient versus inpatient management. Future research should examine the effectiveness of outpatient strategies through conduct of large cohort studies. Other future work could focus on development of decision aids and other tools to facilitate ambulatory approaches.

Cost-effectiveness of outpatient management for febrile neutropenia in children with cancer.

OBJECTIVE: Inpatient management remains the standard of care for treatment of febrile neutropenia (FN) in children with cancer. Clinical data suggest, however, that outpatient management might be a safe and efficacious alternative for patients with low-risk FN episodes. METHODS: A cost-utility model was created to compare 4 treatment strategies for low-risk FN. The base case considered pediatric cancer patients with low-risk FN. The model used a health care payer's perspective and a time horizon of 1 FN episode. Four treatment strategies were evaluated: (1) entire treatment in hospital with intravenous antibiotics (HospIV); (2) early discharge consisting of 48 hours of inpatient observation with intravenous antibiotics followed by oral outpatient treatment (EarlyDC); (3) entirely outpatient management with intravenous antibiotics (HomeIV); and (4) entirely outpatient management with oral antibiotics (HomePO). Outcome measures were quality-adjusted FN episodes (QAFNEs), costs (Canadian dollars), and incremental cost-effectiveness ratios. Parameter uncertainty was assessed with probabilistic sensitivity analyses. RESULTS: The most cost-effective strategy was HomeIV. It was cost-saving ($2732 vs $2757) and more effective (0.66 vs 0.55 QAFNE) as compared with HomePO. EarlyDC was slightly more effective (0.68 QAFNE) but significantly more expensive ($5579) than HomeIV, which resulted in an unacceptably high incremental cost-effectiveness ratio of more than $130 000 per QAFNE. HospIV was the least cost-effective strategy because it was more expensive ($14 493) and less effective (0.65 QAFNE) than EarlyDC. CONCLUSION: The findings of this decision-analytic model indicate that the substantially higher costs of inpatient management cannot be justified on the basis of safety and efficacy considerations or patient/parent preferences.

Supportive care and chelation therapy in MDS: are we saving lives or just lowering iron?

The myelodysplastic syndromes (MDS) are characterized by cytopenias and risk of transformation to acute myeloid leukemia (AML). Although new treatments are available, a mainstay in MDS remains supportive care, which aims to minimize the impact of cytopenias and transfusion of blood products. Red blood cell (RBC) transfusions place patients at risk of iron overload (IOL). In beta-thalassemia major (BTM), IOL from chronic RBC transfusions inevitably leads to organ dysfunction and death. With iron chelation therapy (ICT), survival in BTM improved from the second decade to near normal and correlated with ICT compliance. Effects of ICT in BTM include reversal of cardiac arrhythmias, improvement in left ventricular ejection fraction, arrest of hepatic fibrosis, and reduction of glucose intolerance. It is not clear whether these specific outcomes are applicable to MDS. Although retrospective, recent studies in MDS suggest an adverse effect of transfusion dependence and IOL on survival and AML transformation, and that lowering iron minimizes this impact. These data raise important points that warrant further study. ICT is potentially toxic and cumbersome, is costly, and in MDS patients should be initiated only after weighing potential risks against benefits until further data are available to better justify its use. Since most MDS patients eventually require RBC transfusions, the public health implications both of transfusion dependence and ICT in MDS are considerable. This paper summarizes the impact of cytopenias in MDS and treatment approaches to minimize their impact, with a focus on RBC transfusions and their complications, particularly with respect to iron overload.

Economic evaluation of posaconazole vs. standard azole prophylaxis in high risk neutropenic patients in the Netherlands.

BACKGROUND: Acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) patients experience prolonged neutropenia after treatment with intensive chemotherapy, leading to a high risk of invasive fungal infections (IFI). The present study evaluates the cost effectiveness of posaconazole vs. standard azoles for the prevention of IFIs in neutropenic patients in the Netherlands. METHODS: A decision-tree model was developed using data from a randomized trial that compared posaconazole and standard azole (fluconazole or itraconazole) prophylaxis in neutropenic patients receiving remission-induction chemotherapy for AML/MDS (Cornely et al., N Engl J Med 2007;356:348-359). Following initiation of prophylaxis, clinical events are modeled with chance nodes reflecting probabilities of IFIs, IFI-related death, and death from other causes. Patients surviving the prophylaxis are assumed to have a life expectancy according to the underlying condition. This allows translation of the trial outcomes to a lifetime horizon. Data on life expectancy, quality of life, medical resource consumption and costs were obtained from the literature. Model outcomes include cost per life year (LY) gained and cost per quality adjusted life year (QALY) gained. RESULTS: The total cost (treatment of breakthrough IFI + prophylaxis) for posaconazole amounted to 4412 euros (95% uncertainty interval 3403 euros - 5666 euros), which is -183 euros (-1985 euros to 1564 euros) less than costs with standard azoles. Posaconazole prophylaxis resulted in 0.08 (0.02-0.15) QALYs gained in comparison with prophylaxis with standard azoles. Results from a probabilistic sensitivity analysis indicate that there is a 90% probability that the cost per QALY gained with posaconazole is below 20,000 euros. Additional scenario analyzes with different assumptions confirmed these findings. CONCLUSION: Given the underlying data and assumptions, the economic evaluation demonstrated that posaconazole prophylaxis is expected to be cost-effective compared with fluconazole/itraconazole in neutropenic AML/MDS patients after intensive chemotherapy.

Outcomes and cost of outpatient or inpatient management of 712 patients with febrile neutropenia.

PURPOSE: We retrospectively compared the outcomes and costs of outpatient and inpatient management of low-risk outpatients who presented to an emergency department with febrile neutropenia (FN). PATIENTS AND METHODS: A single episode of FN was randomly chosen from each of 712 consecutive, low-risk solid tumor outpatients who had been treated prospectively on a clinical pathway (1997-2003). Their medical records were reviewed retrospectively for overall success (resolution of all signs and symptoms of infection without modification of antibiotics, major medical complications, or intensive care unit admission) and nine secondary outcomes. Outcomes were assessed by physician investigators who were blinded to management strategy. Outcomes and costs (payer's perspective) in 529 low-risk outpatients were compared with 123 low-risk patients who were psychosocially ineligible for outpatient management (no access to caregiver, telephone, or transportation; residence > 30 minutes from treating center; poor compliance with previous outpatient therapy) using univariate statistical tests. RESULTS: Overall success was 80% among low-risk outpatients and 79% among low-risk inpatients. Response to initial antibiotics was 81% among outpatients and 80% among inpatients (P = .94); 21% of those initially treated as outpatients subsequently required hospitalization. All patients ultimately responded to antibiotics; there were no deaths. Serious complications were rare (1%) and equally frequent between the groups. The mean cost of therapy among inpatients was double that of outpatients ($15,231 v $7,772; P < .001). CONCLUSION: Outpatient management of low-risk patients with FN is as safe and effective as inpatient management of low-risk patients and is significantly less costly.

Blood transfusions in children: a multi-institutional analysis of practices and complications.

BACKGROUND: Blood product transfusions are a valuable health-care resource. Guidelines for transfusion exist, but variability in their application, particularly in children, remains. The risk factors that threaten transfusion safety are well established, but because their occurrence in children is rare, single-institution studies have limited utility in determining the rates of occurrence. An epidemiologic approach that investigates blood transfusions in hospitalized children may help improve our understanding of transfused blood products in this vulnerable population. STUDY DESIGN AND METHODS: This was a nonconcurrent cohort study of pediatric patients not more than 18 years of age hospitalized from 2001 to 2003 at 35 academic children's hospitals that are members of the Pediatric Health Information System (PHIS). RESULTS: A total of 51,720 (4.8%) pediatric patients received blood product transfusions during the study period. Red blood cells (n = 44,632) and platelets (n = 14,274) were the two most frequently transfused products. The rate of transfusions was highest among children with neutropenia, agranulocytosis, and sickle cell crisis. Asian and American Indian patients had important differences in the rate of blood transfusions and their complications. Resource use in terms of length of stay and costs were higher in patients who received transfusion. Of those patients who received transfusions, 492 (0.95%) experienced a complication from the administered blood product. This accounted for a rate of complications of 10.7 per 1,000 units transfused. CONCLUSIONS: The administration of blood products to children is a common practice in academic children's hospitals. Complications associated with these transfused products are rare.

[Congenital bone marrow failure syndromes. The last 20 years by the example of congenital neutropenia]. / Angeborene Störungen der Blutbildung. Die Entwicklung der letzten 20 Jahre am Beispiel der kongenitalen Neutropenie.

Congenital bone marrow failure syndromes are rare diseases characterised by a reduction of mature blood cells (erythrocytes, platelets, neutrophils). Examples of such disorders include congenital aplastic anemia (Fanconi anemia), congenital hypoplastic anemia (Diamond-Blackfan anemia), congenital neutropenias (Kostmann syndrome, cyclic neutropenia, Shwachman-Diamond syndrome and others), and congenital thrombocytopenias (TAR syndrome, amegacaryocytic thrombocytopenia). In Germany the prevalence of congenital bone marrow failure syndromes can be estimated to be 10/1,000,000 children and adolescents. Although rare, these diseases contributed significantly to the current knowledge on normal haematopoiesis. The documentation of rare diseases by patient registries and the cooperation of clinical centres within networks are most important for the resolution of such disorders. In the following, congenital neutropenia will be presented as an example: Until the 1980s congenital neutropenia could only be classified clinically. Few cases had been reported in the literature. All subtypes were therefore collected under the general term "congenital neutropenia". The establishment of an international network of experts and the long-term documentation of the courses of disease in a common database allowed for statistically workable data in response to therapy, secondary diagnoses and the long-term prognosis. A close cooperation with scientists finally led to the characterisation of genetically different disorders with common pathomechanisms.

Mortality, morbidity, and cost associated with febrile neutropenia in adult cancer patients.

BACKGROUND: Hospitalization for febrile neutropenia (FN) in cancer patients is associated with considerable morbidity, mortality, and cost. The study was undertaken to better define mortality, length of stay (LOS), cost, and risk factors associated with mortality and prolonged hospitalization in cancer patients with FN. METHODS: The longitudinal discharge database derived from 115 US medical centers was used to study all adult cancer patients hospitalized with FN between 1995 and 2000, comprising a total of 41,779 patients. Primary outcomes included mortality, LOS, and cost per episode. RESULTS: Overall, in-hospital mortality was 9.5%. Patients without any major comorbidities had a 2.6% risk of mortality, whereas 1 major comorbidity was associated with a 10.3% and more than 1 major comorbidity with a > or = 21.4% risk of mortality, respectively. Mean (median) length of stay was 11.5 (6) days, and the mean (median) cost was $19,110 ($8,376) per episode of FN. Patients hospitalized for > or = 10 days (35% of all patients) accounted for 78% of overall cost. Independent major risk factors for inpatient mortality included invasive fungal infections, Gram-negative sepsis, pneumonia and other lung disease, cerebrovascular, renal, and liver disease. Main predictors for LOS > or = 10 days included leukemia, invasive fungal infections, other types of infection, and several comorbid conditions. CONCLUSION: Factors associated with increased mortality, LOS, and cost in hospitalized adult cancer patients with FN include patient characteristics, type of malignancy, comorbidities, and infectious complications. These factors may be useful in identifying patients at increased risk of serious medical complications and mortality for more aggressive supportive care measures.

Development and implementation of a risk assessment tool for chemotherapy-induced neutropenia.

PURPOSE/OBJECTIVES: To evaluate a tool developed and implemented to help practitioners assess the risk of chemotherapy-induced neutropenia (CIN) and its complications in patients with nonleukemia cancer types. DESIGN: Retrospective survey of chart records. SETTING: Community-based oncology practice. SAMPLE: The medical records of 85 adult patients treated with new courses of chemotherapy, regardless of the cancer type or stage; 50 charts belonged to patients treated before the implementation of the tool and 35 to patients evaluated with the tool. METHODS: A risk assessment tool for CIN that was developed using risk factors from published studies and national guidelines was implemented. Patients who were found to be at increased risk for CIN were given colony-stimulating factor (CSF) support starting with the first chemotherapy cycle. The effectiveness of the tool was evaluated by comparing clinical outcomes before and after the implementation of the risk assessment tool. MAIN RESEARCH VARIABLES: Febrile neutropenia, IV antibiotic use, hospitalization for neutropenia, and chemotherapy dose reductions and delays. FINDINGS: Chemotherapy dose delays, febrile neutropenia, treatment with IV antibiotics, and hospitalization for neutropenia occurred less frequently in patients assessed with the tool and managed with the algorithm for CSF use than in those who were not assessed. CONCLUSIONS: The Risk Assessment for Neutropenic Complications Tool is effective in helping practitioners determine which patients are at high risk for CIN and its complications IMPLICATIONS FOR NURSING: By using the tool to identify patients treated with chemotherapy who need growth factor support, nurses can help to reduce the incidence of neutropenia and its complications.
