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

Ambulatory management of low-risk febrile neutropenia in adult oncological patients. Systematic review

PURPOSE

Recent clinical practice guidelines have recommended ambulatory management of febrile neutropenia in patients with low risk of complications. Although some centers have begun developing management protocols for these patients, there appears to be a certain reluctance to implement them in clinical practice. Our aim is to evaluate the strengths and weaknesses of this strategy according to available evidence and to propose new lines of research.

METHODS

Systematic review using a triple aim approach (efficacy, cost-effectiveness, and quality of life), drawing from literature in MEDLINE (PubMed), Embase, and Cochrane Library databases. The review includes studies that assess ambulatory management for efficacy, cost-efficiency, and quality of life.

RESULTS

The search yielded 27 articles that met our inclusion criteria.

CONCLUSION

In conclusion, based on current evidence, ambulatory management of febrile neutropenia is safe, more cost-effective than inpatient care, and capable of improving quality of life in oncological patients with this complication. Ambulatory care seems to be an effective alternative to hospitalization in these patients.

Willingness to pay for cancer prevention, screening, diagnosis, and treatment: a systematic review

INTRODUCTION

Willingness to pay (WTP) studies examine the maximum amount of money an individual is willing to pay for a specified health intervention, and can be used to inform coverage and reimbursement decisions. Our objectives were to assess how people value cancer-related interventions, identify differences in the methodologies used, and review the trends in studies' publication.

AREAS COVERED

We extracted PubMed and EconLit articles published in 1997-2020 that reported WTP for cancer-related interventions, characterized the methodological differences and summarized each intervention's mean and median WTP values. We reviewed 1,331 abstracts and identified 103 relevant WTP studies, of which 37 (36%) focused on treatment followed by screening (26), prevention (21), diagnosis (7) and other interventions (12). The methods used to determine WTP values were primarily discrete-choice questions (n = 54, 52%), bidding games (15), payment cards (12) and open-ended questions (12). We found a wide variation in WTP reported values ranged from below $100 to over $20,000.

EXPERT OPINION

The WTP literature on oncology interventions has grown rapidly. There is considerable heterogeneity with respect to the type of interventions and diseases assessed, the respondents' characteristics, and the study methodologies. This points to the need to establish international guidelines for best practices in this field.

Willingness-to-pay for cancer treatment and outcome: a systematic review

BACKGROUND

Understanding patient preferences in cancer management is essential for shared decision-making. Patient or societal willingness-to-pay (WTP) for desired outcomes in cancer management represents their preferences and values of these outcomes.

OBJECTIVE

The aim of this systematic review is to critically evaluate how current literature has addressed WTP in relation to cancer treatment and achievement of outcomes.

METHODS

Seven databases were searched from inception until 2 March 2021 to include studies with primary data of WTP values for cancer treatments or achievement of outcomes that were elicited using stated preference methods.

RESULTS

Fifty-four studies were included in this review. All studies were published after year 2000 and more than 90% of the studies were conducted in high-income countries. Sample size of the studies ranged from 35 to 2040, with patient being the most studied population. There was a near even distribution between studies using contingent valuation and discrete choice experiment. Based on the included studies, the highest WTP values were for a quality-adjusted life year (QALY) ($11,498-$589,822), followed by 1-year survival ($3-$198,576), quality of life (QoL) improvement ($5531-$139,499), and pain reduction ($79-$94,662). Current empirical evidence suggested that improvement in QoL and pain reduction had comparable weights to survival in cancer management.

CONCLUSION

This systematic review provides a summary on stated preference studies that elicited patient preferences via WTP and summarised their respective values. Respondents in this review had comparable WTP for 1-year survival and QoL, suggesting that improvement in QoL should be emphasised together with survival in cancer management.

Comparison of Approaches for Measuring Adherence and Persistence to Oral Oncologic Therapies in Patients Diagnosed with Metastatic Renal Cell Carcinoma

BACKGROUND

Adherence and persistence studies face several methodologic difficulties, including short-term mortality. We compared approaches to quantify adherence and persistence to first line (1L) oral targeted therapy (TT) in patients diagnosed with metastatic renal cell carcinoma (mRCC).

METHODS

Patients with mRCC ages 66 years or more who initiated TTs within 4 months of diagnosis were identified in the Surveillance, Epidemiology, and End Results Medicare-linked database (2007-2015). Adherence [proportion of days covered (PDC) >80%] was calculated using (i) PDC with a fixed 6-month denominator including then excluding patients who died within the 6 months and (ii) PDC with a denominator measuring time on treatment. Risk of nonpersistence was obtained by censoring death or treating death as a competing risk using cumulative incidence functions.

RESULTS

Among 485 patients with mRCC initiating a 1L oral TT (sunitinib, 64%; pazopanib, 25%; other, 11%), 40% died within 6 months. Adherence was higher after restricting to patients who survived (60%) compared with including those patients and assigning zero days covered after death (47%). Risk of nonpersistence was higher when censoring patients at death, 0.91 [95% confidence interval (CI), 0.88-0.94], compared with treating death as a competing risk, 0.75 (95% CI, 0.71-0.79).

CONCLUSIONS

Different approaches to handling death resulted in different adherence and persistence estimates in the metastatic setting. Future studies should explicitly report the proportion of patient deaths over time and explore appropriate methods to account for death as competing risk.

IMPACT

Use of several approaches can provide a more comprehensive picture of medication-taking behavior in the metastatic setting where death is a major competing risk.

Potential reduction of hospital stay length with outpatient management of low-risk febrile neutropenia in a regional cancer center

Background

Febrile neutropenia is a serious complication of chemotherapy. The Multinational Association for Supportive Care in Cancer (MASCC) risk index score identifies patients at low risk of serious complications. Outpatient management programs have been successfully piloted in other Australian metropolitan cancer centers.

Aim

To assess current management of febrile neutropenia at our regional cancer center and determine potential impacts of an outpatient management program.

Method

We performed a retrospective review of medical records for all patients admitted at our regional institution with febrile neutropenia between 1 January 2016, and 31 December 2018. We collected information regarding patient characteristics, determined the MASCC risk index score, and if low risk, we determined the eligibility for outpatient care and potential reduction in length of stay and cost benefit.

Results

A total of 98 hospital admissions were identified. Of these, 66 had a MASCC low‐risk index score. Fifty‐eight patients met the eligibility criteria for outpatient management. Seventy‐one percent were female. The most common tumor type was breast cancer. Forty‐eight percent were treated with curative intent. The median length of stay was 3 days. The median potential reduction in length of stay for each admission was 2 days. The total potential reduction in length of stay was 198 days. No admission resulted in serious complications.

Conclusion

This review demonstrates a significant number of hospital admission days can be avoided. We intend to conduct a prospective pilot study at our center to institute an outpatient management program for such low‐risk patients with potential reduction in hospital length of stay. This will have significant implications on health resource usage, service provision planning, and patient quality of life.

National cost savings from an ambulatory program for low-risk febrile neutropenia patients in Australia

Objective The management of low-risk febrile neutropenia (FN) patients through ambulatory programs has demonstrated comparative safety and effectiveness to in-patient strategies. However, there is limited evidence of benefits of changing practice, particularly on a national scale. The aim of this study was to estimate costs and benefits of the program over a 10-year time horizon. Methods A comparative cost analysis from a health system perspective was performed, comparing costs and length of stay (LOS) of patients enrolled in an ambulatory program to a historical cohort who did not receive the program. Generalised linear models were used for analysis and bootstrapped to account for uncertainty. National data of identified FN admissions were used to inform future projections, with varying proportions of low-risk patients and eligibility for the ambulatory program. Results The overall LOS for patients in ambulatory cohort was 1.9 days shorter (95% confidence interval (CI) 1.0-2.8 days), a 50% reduction in in-patient bed-days. Although patients in the ambulatory cohort incurred additional costs due to care received outside hospital (mean (± s.d.) A$828.03 ± 124.30), the mean total cost incurred remained substantially lower than that of the historical cohort (A$2979 lower; 95% CI A$772-5391). On a national scale, this could translate into A$62.7 million in costs averted and 41347 bed-days saved over 10 years if the low-risk prediction rate and eligibility for ambulatory programs remained at currently observed rates. Conclusions The wider implementation of a safe and effective ambulatory program to manage low-risk FN patients can result in significant return-on-investment for the healthcare system by eliminating avoidable costs due to unnecessary lengthy hospital admissions. What is known about the topic? There is strong evidence demonstrating out-patient treatment of low-risk FN patients to be an effective and cost-effective strategy compared with continued in-patient hospitalisation. What does this paper add? This study demonstrates the sustainability of the ambulatory program in ensuring cost benefits and in-patient beds through real-life implementation data. It also provides evidence of the substantial cost and bed-days potentially averted when the cost savings and difference in LOS are estimated on a national scale over a 10-year time horizon. What are the implications for practitioners? The management of low-risk FN patients through ambulatory or out-patient programs is a safe and effective approach. There is strong evidence demonstrating the likely cost savings and considerable bed-days saved, which can be reallocated to meet other medical demands.

Neutropénie fébrile aux urgences, stratification du risque et conditions du retour à domicile

La neutropénie fébrile (NF) est une situation fréquemment rencontrée aux urgences avec un taux de mortalité non négligeable variant de 5 à 40 %. Cette variabilité importante met en avant l’importance de stratifier le risque afin de permettre un traitement ambulatoire per os de certains patients à faible risque. En plus du MASCC (The Multinational Association for Supportive Care in Cancer) score, d’autres outils permettent d’évaluer ce risque ou sont à l’étude dans ce but, tels que le dosage de la CRP, la procalcitonine ou encore le score CISNE. Après une prise en charge rapide aux urgences incluant l’administration sans délai d’un traitement adéquat, la poursuite de l’antibiothérapie per os à domicile est envisageable chez les patients à faible risque. La combinaison amoxicilline–acide clavulanique et ciprofloxacine est le plus souvent recommandée, mais la moxifloxacine ou la lévofloxacine en monothérapie peuvent également être utilisées pour les patients traités à domicile. Le retour à domicile permet de réduire fortement les coûts engendrés par l’hospitalisation, de diminuer le risque d’infection nosocomiale et d’améliorer la qualité de vie des patients avec NF à faible risque. Dans cette optique, plusieurs critères doivent être remplis, et une discussion avec le patient reste primordiale à la prise de décision. Parmi ceux-ci, nous retiendrons notamment un score MASCC supérieur à 21, une durée attendue de neutropénie inférieure à sept jours, l’accord du patient et de son entourage ainsi que la proximité entre le domicile et un service de soin adapté.

Meta-ethnography of experiences of early discharge, with a focus on paediatric febrile neutropenia

PURPOSE (STATING THE MAIN PURPOSES AND RESEARCH QUESTION)

Many children have no significant sequelae of febrile neutropenia. A systematic review of clinical studies demonstrated patients at low risk of septic complications can be safely treated as outpatients using oral antibiotics with low rates of treatment failure. Introducing earlier discharge may improve quality of life, reduce hospital acquired infection and reduce healthcare service pressures. However, the review raised concerns that this might not be acceptable to patients, families and healthcare professionals.

METHODS

This qualitative synthesis explored experiences of early discharge in paediatric febrile neutropenia, including reports from studies of adult febrile neutropenia and from other paediatric conditions. Systematic literature searching preceded meta-ethnographic analysis, including reading the studies and determining relationships between studies, translation of studies and synthesis of these translations.

RESULTS

Nine papers were included. The overarching experience of early discharge is that decision-making is complex and difficult and influenced by fear, timing and resources. From this background, we identified two distinct themes. First, participants struggled with practical consequences of treatment regimens, namely childcare, finances and follow-up. A second theme identified social and emotional issues, including isolation, relational and environmental challenges. Linking these, participants considered continuity of care and the need for information important.

CONCLUSIONS

Trust and confidence appeared interdependent with resources available to families-both are required to manage early discharge. Socially informed resilience is relevant to facilitating successful discharge strategies. Interventions which foster resilience may mediate the ability and inclination of families to accept early discharge. Services have an important role in recognising and enhancing resilience.

Acute Oncology Care: A narrative review of the acute management of neutropenic sepsis and immune-related toxicities of checkpoint inhibitors

Cancer care has become increasingly specialized and advances in therapy have resulted in a larger number of patients receiving care. There has been a significant increase in the number of patients presenting with cancer related emergencies including treatment toxicities and those directly related to the malignancy. Suspected neutropenic sepsis is an acute medical emergency and empirical antibiotic therapy should be administered immediately. The goal of empirical therapy is to cover the most likely pathogens that will cause life-threatening infections in neutropenic patients. Patients with febrile neutropenia are a heterogeneous group with only a minority of treated patients developing significant medical complications. Outpatient management of low risk febrile neutropenia patients identified by the MASCC score is a safe and effective strategy. Immunotherapy with "checkpoint inhibitors" has significantly improved outcomes for patients with metastatic melanoma and evidence of benefit in a wide range of malignancies is developing. Despite these clinical benefits a number of immune related adverse events have been recognised which can affect virtually all organ systems and are potentially fatal. The timing of the onset of the adverse events is dependent on the organ system affected and unlike anti-neoplastic therapy can be delayed significantly after initiation or completion of therapy. The field of Acute Oncology is changing rapidly. Alongside, the traditional challenge of neutropenic sepsis there are many emerging toxicities. Further research into the optimal management, strategies and pathways of acutely unwell patients with cancer is required.

Clinical and cost-effectiveness, safety and acceptability of community intravenous antibiotic service models: CIVAS systematic review

OBJECTIVE

Evaluate evidence of the efficacy, safety, acceptability and cost-effectiveness of outpatient parenteral antimicrobial therapy (OPAT) models.

DESIGN

A systematic review.

DATA SOURCES

MEDLINE, EMBASE, CINAHL, Cochrane Library, National Health Service (NHS) Economic Evaluation Database (EED), Research Papers in Economics (RePEc), Tufts Cost-Effectiveness Analysis (CEA) Registry, Health Business Elite, Health Information Management Consortium (HMIC), Web of Science Proceedings, International Pharmaceutical Abstracts, British Society for Antimicrobial Chemotherapy website. Searches were undertaken from 1993 to 2015.

STUDY SELECTION

All studies, except case reports, considering adult patients or practitioners involved in the delivery of OPAT were included. Studies combining outcomes for adults and children or non-intravenous (IV) and IV antibiotic groups were excluded, as were those focused on process of delivery or clinical effectiveness of 1 antibiotic over another. Titles/abstracts were screened by 1 reviewer (20% verified). 2 authors independently screened studies for inclusion.

RESULTS

128 studies involving >60 000 OPAT episodes were included. 22 studies (17%) did not indicate the OPAT model used; only 29 involved a comparator (23%). There was little difference in duration of OPAT treatment compared with inpatient therapy, and overall OPAT appeared to produce superior cure/improvement rates. However, when models were considered individually, outpatient delivery appeared to be less effective, and self-administration and specialist nurse delivery more effective. Drug side effects, deaths and hospital readmissions were similar to those for inpatient treatment, but there were more line-related complications. Patient satisfaction was high, with advantages seen in being able to resume daily activities and having greater freedom and control. However, most professionals perceived challenges in providing OPAT.

CONCLUSIONS

There were no systematic differences related to the impact of OPAT on treatment duration or adverse events. However, evidence of its clinical benefit compared with traditional inpatient treatment is lacking, primarily due to the dearth of good quality comparative studies. There was high patient satisfaction with OPAT use but the few studies considering practitioner acceptability highlighted organisational and logistic barriers to its delivery.

The Community IntraVenous Antibiotic Study (CIVAS): a mixed-methods evaluation of patient preferences for and cost-effectiveness of different service models for delivering outpatient parenteral antimicrobial therapy

Background

Outpatient parenteral antimicrobial therapy (OPAT) is widely used in most developed countries, providing considerable opportunities for improved cost savings. However, it is implemented only partially in the UK, using a variety of service models.

Objectives

The aims of this research were to (1) establish the extent of OPAT service models in England and identify their development; (2) evaluate patients’ preferences for different OPAT service delivery models; (3) assess the cost-effectiveness of different OPAT service delivery models; and (4) convene a consensus panel to consider our evidence and make recommendations.

Methods

This mixed-methods study included seven centres providing OPAT using four main service models: (1) hospital outpatient (HO) attendance; (2) specialist nurse (SN) visiting at home; (3) general nurse (GN) visiting at home; and (4) self-administration (SA) or carer administration. Health-care providers were surveyed and interviewed to explore the implementation of OPAT services in England. OPAT patients were interviewed to determine key service attributes to develop a discrete choice experiment (DCE). This was used to perform a quantitative analysis of their preferences and attitudes. Anonymised OPAT case data were used to model cost-effectiveness with both Markov and simulation modelling methods. An expert panel reviewed the evidence and made recommendations for future service provision and further research.

Results

The systematic review revealed limited robust literature but suggested that HO is least effective and SN is most effective. Qualitative study participants felt that different models of care were suited to different types of patient and they also identified key service attributes. The DCE indicated that type of service was the most important factor, with SN being strongly preferred to HO and SA. Preferences were influenced by attitudes to health care. The results from both Markov and simulation models suggest that a SN model is the optimal service for short treatment courses (up to 7 days). Net monetary benefit (NMB) values for HO, GN and SN services were £2493, £2547 and £2655, respectively. For longer treatment, SA appears to be optimal, although SNs provide slightly higher benefits at increased cost. NMB values for HO, GN, SN and SA services were £8240, £9550, £10,388 and £10,644, respectively. The simulation model provided useful information for planning OPAT services. The expert panel requested more guidance for service providers and commissioners. Overall, they agreed that mixed service models were preferable.

Limitations

Recruitment to the qualitative study was suboptimal in the very elderly and ethnic minorities, so the preferences of patients from these groups might not be represented. The study recruited from Yorkshire, so the findings may not be applicable nationally.

Conclusions

The quantitative preference analysis and economic modelling favoured a SN model, although there are differences between sociodemographic groups. SA provides cost savings for long-term treatment but is not appropriate for all.

Future work

Further research is necessary to replicate our results in other regions and populations and to evaluate mixed service models. The simulation modelling and DCE methods used here may be applicable in other health-care settings.

Outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer

The purpose of this study was to retrospectively analyze the feasibility of outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer. A total of 131 consecutive patients with breast cancer treated with adjuvant or neoadjuvant chemotherapy from 2011 to 2013 at Osaka Medical College Hospital (Osaka, Japan) were retrospectively reviewed. In the case of developing a fever (body temperature, ≥38°C), the outpatients had been instructed to take previously prescribed oral antibiotics for 3 days without any initial assessment, and if no improvement had occurred by then, they were required to visit the hospital for examination and to undergo treatment based on the results of a risk assessment for complications. The primary aim of the present study was to assess the outcome of febrile episodes, while the secondary aim was to assess the incidence of febrile episodes, hospitalizations, and the type of chemotherapy. The 131 patients received 840 chemotherapy administrations. Fifty-five patients (42.0%) had a total of 75 febrile episodes after 840 chemotherapy administrations (8.9%). Treatment failure occurred in 12 of the 75 episodes (16.0%) in 11 of the 55 patients (20.0%). Only four episodes required hospitalization. Treatment success was achieved in 63 episodes (84.0%). In conclusion, the feasibility of outpatient management without initial assessment was evaluated in the present study for febrile patients undergoing adjuvant chemotherapy for breast cancer, and the outpatient strategy regimen may be safe and convenient for these patients.

ReCAP: Hospitalizations in Older Adults With Advanced Cancer: The Role of Chemotherapy

PURPOSE

Hospital readmissions are often cited as a marker of poor quality of care. Limited data suggest some readmissions may be preventable depending upon definitions and available outpatient support.

METHODS

General criteria to define preventable and not preventable admissions were developed before data collection began. The records of sequential nonsurgical oncology readmissions were reviewed independently by two reviewers. When the reviewers disagreed about assigning admissions as preventable or not preventable, a third reviewer was the tie breaker. The reasons for assigning admissions as preventable or not preventable were analyzed.

RESULTS

Seventy-two readmissions occurring among 69 patients were analyzed. The first two reviewers agreed that 18 (25%) of 72 were preventable and that 29 (40%) of 72 were not. A third reviewer found four of the split 25 cases to be preventable; therefore, the consensus preventability rate was 22 (31%) of 72. The most common causes of preventability were overwhelming symptoms in patients who qualified for hospice but were not participating in hospice and insufficient communication between patients and the care team about symptom burden. The most common reason for assignment of a not preventable admission was a high symptom burden among patients without strong indications for hospice or for whom aggressive outpatient management was inadequate. The median survival after readmission was 72 days.

CONCLUSION

A substantial proportion of oncology readmissions could be prevented with better anticipation of symptoms in high-risk ambulatory patients and enhanced communication about symptom burden between patients and physicians before an escalation that leads to an emergency department visit. Managing symptoms in patients who are appropriate for hospice is challenging. Readmission is a marker of poor prognosis.

Systematic review of reduced therapy regimens for children with low risk febrile neutropenia

PURPOSE

Reduced intensity therapy for children with low-risk febrile neutropenia may provide benefits to both patients and the health service. We have explored the safety of these regimens and the effect of timing of discharge.

METHODS

Multiple electronic databases, conference abstracts and reference lists were searched. Randomised controlled trials (RCT) and prospective observational cohorts examining the location of therapy and/or the route of administration of antibiotics in people younger than 18 years who developed low-risk febrile neutropenia following treatment for cancer were included. Meta-analysis using a random effects model was conducted. I (2) assessed statistical heterogeneity not due to chance.

REGISTRATION

PROSPERO (CRD42014005817).

RESULTS

Thirty-seven studies involving 3205 episodes of febrile neutropenia were included; 13 RCTs and 24 prospective observational cohorts. Four safety events (two deaths, two intensive care admissions) occurred. In the RCTs, the odds ratio for treatment failure (persistence, worsening or recurrence of fever/infecting organisms, antibiotic modification, new infections, re-admission, admission to critical care or death) with outpatient treatment was 0.98 (95% confidence interval (95%CI) 0.44-2.19, I (2) = 0 %) and with oral treatment was 1.05 (95%CI 0.74-1.48, I (2) = 0 %). The estimated risk of failure using outpatient therapy from all prospective data pooled was 11.2 % (95%CI 9.7-12.8 %, I (2) = 77.2 %) and using oral antibiotics was 10.5 % (95%CI 8.9-12.3 %, I (2) = 78.3 %). The risk of failure was higher when reduced intensity therapies were used immediately after assessment, with lower rates when these were introduced after 48 hours.

CONCLUSIONS

Reduced intensity therapy for specified groups is safe with low rates of treatment failure. Services should consider how these can be acceptably implemented.

Patient-reported preferences for oral versus intravenous administration for the treatment of cancer: a review of the literature

OBJECTIVE

The emergence of various modes of administration for cancer treatment, including oral administration, brings into focus the importance of patient preference for administration. The purpose of this research was to evaluate the administration preferences of cancer patients, specifically between oral and intravenous (IV) treatment, as well as the factors contributing to preference.

METHODS

A literature search was conducted in OvidSP to identify research in which the preferences of cancer patients for oral or IV treatment have been evaluated. Data were analyzed in two stages: 1) those articles that directly compared preference between modes of administration were tallied to determine explicit preference for oral or IV treatment; and 2) all attributes associated with patient preference were documented.

RESULTS

Of the 48 abstracts identified as part of the initial OvidSP search, eight articles were selected for full-text review. One article was removed following full-text review, and seven additional articles were identified through a gray literature search, yielding a total of 14 articles for evaluation. In Stage 1, 13 of the 14 articles compared preference, of which eleven articles (84.6%) reported that patients preferred oral treatment over IV, while two (15.4%) stated that cancer patients preferred IV treatment over oral. In Stage 2, the most frequently reported attributes contributing to preference included convenience, ability to receive treatment at home, treatment schedule, and side effects.

DISCUSSION

Evidence suggests that oncology patients prefer oral treatment to IV. Rationale for preference was due to a number of factors, including convenience, perception of efficacy, and past experience. Further evaluation should be conducted, given the limited data on patient preference in oncology.

Preference for pharmaceutical formulation and treatment process attributes

PURPOSE

Pharmaceutical formulation and treatment process attributes, such as dose frequency and route of administration, can have an impact on quality of life, treatment adherence, and disease outcomes. The aim of this literature review was to examine studies on preferences for pharmaceutical treatment process attributes, focusing on research in diabetes, oncology, osteoporosis, and autoimmune disorders.

METHODS

The literature search focused on identifying studies reporting preferences for attributes of the pharmaceutical treatment process. Studies were required to use formal quantitative preference assessment methods, such as utility valuation, conjoint analysis, or contingent valuation. Searches were conducted using Medline, EMBASE, Cochrane Library, Health Economic Evaluation Database, and National Health Service Economic Evaluation Database (January 1993-October 2013).

RESULTS

A total of 42 studies met inclusion criteria: 19 diabetes, nine oncology, five osteoporosis, and nine autoimmune. Across these conditions, treatments associated with shorter treatment duration, less frequent administration, greater flexibility, and less invasive routes of administration were preferred over more burdensome or complex treatments. While efficacy and safety often had greater relative importance than treatment process, treatment process also had a quantifiable impact on preference. In some instances, particularly in diabetes and autoimmune disorders, treatment process attributes had greater relative importance than some or all efficacy and safety attributes. Some studies suggested that relative importance of treatment process depends on disease (eg, acute vs chronic) and patient (eg, injection experience) characteristics.

CONCLUSION

Despite heterogeneity in study methods and design, some general patterns of preference clearly emerged. Overall, the results of this review suggest that treatment process has a quantifiable impact on preference and willingness to pay for treatment, even in many situations where safety and efficacy were the primary concerns. Patient preferences for treatment process attributes can inform drug development decisions to better meet the needs of patients and deliver improved outcomes.

Health state utilities associated with attributes of treatments for hepatitis C

BACKGROUND

Cost-utility analyses are frequently conducted to compare treatments for hepatitis C, which are often associated with complex regimens and serious adverse events. Thus, the purpose of this study was to estimate the utility associated with treatment administration and adverse events of hepatitis C treatments.

DESIGN

Health states were drafted based on literature review and clinician interviews. General population participants in the UK valued the health states in time trade-off (TTO) interviews with 10- and 1-year time horizons. The 14 health states described hepatitis C with variations in treatment regimen and adverse events.

RESULTS

A total of 182 participants completed interviews (50% female; mean age = 39.3 years). Utilities for health states describing treatment regimens without injections ranged from 0.80 (1 tablet) to 0.79 (7 tablets). Utilities for health states describing oral plus injectable regimens were 0.77 (7 tablets), 0.75 (12 tablets), and 0.71 (18 tablets). Addition of a weekly injection had a disutility of -0.02. A requirement to take medication with fatty food had a disutility of -0.04. Adverse events were associated with substantial disutilities: mild anemia, -0.12; severe anemia, -0.32; flu-like symptoms, -0.21; mild rash, -0.13; severe rash, -0.48; depression, -0.47. One-year TTO scores were similar to these 10-year values.

CONCLUSIONS

Adverse events and greater treatment regimen complexity were associated with lower utility scores, suggesting a perceived decrease in quality of life beyond the impact of hepatitis C. The resulting utilities may be used in models estimating and comparing the value of treatments for hepatitis C.

Management of breast cancer patients with chemotherapy-induced neutropenia or febrile neutropenia

Chemotherapy-induced neutropenia (CIN) is a common toxicity caused by the administration of anticancer drugs. This side effect is associated with life-threatening infections and may alter the chemotherapy schedule, thus impacting on early and long-term outcomes. Elderly breast cancer patients with impaired health status or advanced disease as well as patients undergoing dose-dense anthracycline/taxane- or docetaxel-based regimens have the highest risk of CIN. A careful assessment of the baseline risk for CIN allows the selection of patients who need primary prophylaxis with granulocyte colony-stimulating factor (G-CSF) and/or antimicrobial agents. Neutropenic cancer patients may develop febrile neutropenia and CIN-related severe medical complications. Specific risk assessment scores, along with comprehensive clinical evaluation, are able to define a group of febrile patients with low risk for complications who can be safely treated as outpatients. Conversely, patients with higher risk of severe complications should be hospitalized and should receive intravenous antibiotic therapy with or without G-CSF.

Protocol for a systematic review of reductions in therapy for children with low-risk febrile neutropenia

BACKGROUND

Febrile neutropenia is a common complication of therapy in children with cancer. Some patients are at low risk of complications, and research has considered reduction in therapy for these patients. A previous systematic review broadly considered whether outpatient treatment and oral antibiotics were safe in this context and concluded that this was likely to be the case. Since that review, there has been further research in this area. Therefore, we aim to provide a more robust answer to these questions and to additionally explore whether the exact timing of discharge, including entirely outpatient treatment, has an impact on outcomes.

METHODS/DESIGN

The search will cover MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, CDSR, CENTRAL, LILACS, HTA and DARE. A full search strategy is provided. Key conference proceedings and reference lists of included papers will be hand searched. Prominent authors/clinicians in the field will be contacted. We will include randomised and quasi-randomised controlled trials along with prospective single-arm studies that examine the location of therapy and/or the route of administration of antibiotics in children or young adults (aged less than 18 years) who attend paediatric services with fever and neutropenia due to treatment for cancer and are assessed to be at low risk of medical complications. Studies will be screened and data extracted by one researcher and independently checked by a second. All studies will be critically appraised using tools appropriate to the study design. Data from randomised controlled trials (RCTs) will be combined to provide comparative estimates of treatment failure, safety and adequacy. Information from quasi-randomised trials and single-arm studies will provide further data on the safety and adequacy of regimes. Random effects meta-analysis will be used to combine studies. A detailed analysis plan, including assessment of heterogeneity and publication bias, is provided.

DISCUSSION

This study will aim to specifically define the features of a low-risk strategy that will maintain levels of safety and adequacy equivalent to those of traditional treatments. This will both inform the development of services and provide patients and families with data to help them make an informed decision about care.

Utilities associated with subcutaneous injections and intravenous infusions for treatment of patients with bone metastases

INTRODUCTION

Although cost-utility models are often used to estimate the value of treatments for metastatic cancer, limited information is available on the utility of common treatment modalities. Bisphosphonate treatment for bone metastases is frequently administered via intravenous infusion, while a newer treatment is administered as a subcutaneous injection. This study estimated the impact of these treatment modalities on health state preference.

METHODS

Participants from the UK general population completed time trade-off interviews to assess the utility of health state vignettes. Respondents first rated a health state representing cancer with bone metastases. Subsequent health states added descriptions of treatment modalities (ie, injection or infusion) to this basic health state. The two treatment modalities were presented with and without chemotherapy, and infusion characteristics were varied by duration (30 minutes or 2 hours) and renal monitoring.

RESULTS

A total of 121 participants completed the interviews (52.1% female, 76.9% white). Cancer with bone metastases had a mean utility of 0.40 on a standard utility scale (1 = full health; 0 = dead). The injection, 30-minute infusion, and 2-hour infusion had mean disutilities of -0.004, -0.02, and -0.04, respectively. The mean disutility of the 30-minute infusion was greater with renal monitoring than without. Chemotherapy was associated with substantial disutility (-0.17). When added to health states with chemotherapy, the mean disutilities of injection, 30-minute infusion, and 2-hour infusion were -0.02, -0.03, and -0.04, respectively. The disutility associated with injection was significantly lower than the disutility of the 30-minute and 2-hour infusions (P < 0.05), regardless of chemotherapy status.

CONCLUSION

Respondents perceived an inconvenience with each type of treatment modality, but injections were preferred over infusions. The resulting utilities may be used in cost-utility models examining the value of treatments for the prevention of skeletal-related events in patients with bone metastases.

The Multinational Association for Supportive Care in Cancer (MASCC) risk index score: 10 years of use for identifying low-risk febrile neutropenic cancer patients

The Multinational Association for Supportive Care in Cancer risk index score developed, through a multinational collaboration, was published in 2000 with the aim to identify patients with chemotherapy-induced febrile neutropenia at low risk of serious medical complication development. It has been endorsed as a reliable tool since 2002 by Infectious Diseases Society of America. Ten years after, we thought worth to review its use, its characteristics in the external validations that occurred after the initial publication and also to review how the recognition of a group of patients at low risk has changed the management of febrile neutropenia. We also raise the issue of identification of high-risk patients that remains a challenge today.
