Asystematic literature review of economic evaluations and cost-of-illness studies of inherited cardiomyopathies.

Hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) are commonly inherited heart conditions associated with ahigh risk of heart failure and sudden cardiac death. To understand the economic and societal disease burden, this study systematically identified and reviewed cost-of-illness (COI) studies and economic evaluations (EEs) of various interventions for HCM and DCM. Aliterature search was performed in MEDLINE, EMBASE, NHS EED, EconLit and Web of Science to identify COI studies and EEs published between 1January 2010 and 28April 2021. The selection of studies and their critical appraisal were performed jointly by two independent researchers. For the quality assessment, the 'Consensus on Health Economic Criteria' list was used. Two COI studies and 11EEs were eligible for inclusion. Cost-effectiveness varied among interventions and depended on the targeted patient population. Both COI studies identified only hospitalisation costs in HCM. The mean study quality was high in EEs but low in COI studies. Most studies excluded costs for patients, caregivers and productivity losses. Overall, knowledge of the societal and economic burden of inherited cardiomyopathies is limited. Future research needs to include quality-adjusted life years and abroader range of costs to provide an information base for optimising care for affected patients.

A Systematic Literature Review of Economic Evaluations and Cost Studies of the Treatment of Psoriasis, Atopic Dermatitis, and Chronic Urticaria.

IntroductionPsoriasis (PSO), atopic dermatitis (AD), and chronic urticaria (CU) are common manifestations of immunological skin and subcutaneous conditions and have been shown to have a substantial impact on the quality of life of patients. The cost of treating those conditions can also be high, as the use of biologic treatments has become more common for moderate to severe patients. In this review, we examine characteristics of economic evaluations and cost studies conducted for the three conditions.MethodsA literature search was conducted using PubMed, Embase, and the Cochrane Library from January 1, 2016 to October 26, 2020 to identify economic evaluations where the cost of one or more drug treatment was evaluated and cost studies covering any intervention type. Each database was searched using keyword and MeSH terms related to treatment costs (e.g., health care cost, drug cost, etc.) and each condition (e.g., PSO, AD, eczema, CU, etc.).ResultsA total of 123 studies were reviewed, including 104 studies (85%) of PSO (including psoriasis, plaque psoriasis, psoriatic arthritis, and psoriasis vulgaris), 14 studies (11%) of AD, and 5 studies (4%) of CU. Seventy-two studies (59%) reviewed reported the inclusion of biologic treatments, 10 studies (8%) did not include biologic treatments, and 41 studies (33%) did not report whether or not a biologic treatment was included. While nearly all studies (98%) included direct costs, only 22 studies (18%) included indirect costs.ConclusionsEconomic evaluations for AD and CU may be needed in order to better understand the value of new treatments. Moreover, a clearer delineation for biologic treatments and indirect costs (i.e., productivity losses and gains) may be required.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13555-022-00774-2.

Defining a Core Data Set for the Economic Evaluation of Precision Oncology

ObjectivesPrecision oncology is generating vast amounts of multiomic data to improve human health and accelerate research. Existing clinical study designs and attendant data are unable to provide comparative evidence for economic evaluations. This lack of evidence can cause inconsistent and inappropriate reimbursement. Our study defines a core data set to facilitate economic evaluations of precision oncology. MethodsWe conducted a literature review of economic evaluations of next-generation sequencing technologies, a common application of precision oncology, published between 2005 and 2018 and indexed in PubMed (MEDLINE). Based on this review, we developed a preliminary core data set for informal expert feedback. We then used a modified-Delphi approach with individuals involved in implementation and evaluation of precision medicine, including 2 survey rounds followed by a final voting conference to refine the data set. ResultsTwo authors determined that variation in published data elements was reached after abstraction of 20 economic evaluations. Expert consultation refined the data set to 83 unique data elements, and a multidisciplinary sample of 46 experts participated in the modified-Delphi process. A total of 68 elements (81%) were selected as required, spanning demographics and clinical characteristics, genomic data, cancer treatment, health and quality of life outcomes, and resource use. ConclusionsCost-effectiveness analyses will fail to reflect the real-world impacts of precision oncology without data to accurately characterize patient care trajectories and outcomes. Data collection in accordance with the proposed core data set will promote standardization and enable the generation of decision-grade evidence to inform reimbursement.

A protocol for a systematic literature review of economic evaluation studies of interventions to address antimicrobial resistance

BackgroundAntimicrobial resistance (AMR) is accelerated by the widespread and often indiscriminate use of antimicrobials in humans, animals, and the environment. In 2015, the World Health Organization recognised AMR as one of the top ten global health threats, due to its potential to neutralise humanity’s advancements in western medicine by enabling the emergence of new strains of existing pathogens, many of which have no available treatments. Over the past decade, several countries, including those in low- and middle-income contexts, have started implementing interventions to tackle AMR. However, economic evidence regarding the cost-effectiveness of these interventions remains weak. To address this evidence gap, we will conduct a systematic literature review to provide a comprehensive summary on the value for money of different AMR interventions.MethodsWe aim to conduct a systematic literature review of all available economic evaluations on interventions addressing AMR and will provide a narrative synthesis of our findings. Systematic searches for relevant studies will be performed across all suitable databases as well as in grey literature sources such as unpublished studies, reports, and other relevant documents. All economic evaluation studies will be included as long as they report an economic outcome and have stated that the analysed intervention will reduce antimicrobial resistance or antimicrobial use in the abstract. Those studies reporting clinical endpoints alone will be excluded. Selection for final inclusion and data extraction will be performed by two independent reviewers.DiscussionThe review will be one of the first of its kind, and the most recent, to systematically review literature on the cost-effectiveness of AMR interventions, an important evidence gap in the economics of AMR. The findings will enable policy and decision-makers, particularly in resource-constrained settings, to better use available resources when selecting interventions to address AMR burdens,Systematic review registrationPROSPERO CRD42020190310

A systematic review of economic evaluations of advanced therapy medicinal products.

AimsAdvanced therapy medicinal products (ATMPs) represent a new category of medicinal products with a potential for transformative improvements in health outcomes but at exceptionally high prices. Routine adoption of ATMPs requires robust evidence of their cost‐effectiveness.MethodsA systematic literature review of economic evaluations of ATMPs, including gene therapies, somatic cell therapies and tissue‐engineered products, was conducted. Literature was searched using MedLine, Embase, PubMed, Cochrane Register, the NHS Economic Evaluation Database and the grey literature of health technology assessment organisations with search terms relating to ATMPs and economic evaluations. Titles were screened independently by 2 reviewers. Articles deemed to meet the inclusion criteria were screened independently on abstract, and full texts reviewed. Study findings were appraised critically.Results4514 articles were identified, of which 23 met the inclusion criteria. There was some evidence supporting the cost‐effectiveness of: chimeric antigen receptor T‐cell therapy axicabtagene–ciloleucel (Yescarta), embryonic neural stem cells, tumour infiltrating lymphocytes, in vitro expanded myoblast, autologous chondrocyte implantation, ex vivo gene therapy (Strimvelis) and voretigene neparvovec (Luxturna). However, estimates of cost‐effectiveness were associated with significant uncertainty and high likelihood of bias, resulting from largely unknown long‐term outcomes, a paucity of evidence on health state utilities and extensive modelling assumptions.ConclusionThere are critical limitations to the economic evidence for ATMPs, most notably in relation to evidence on the durability of treatment effect, and the reliability of opinion‐based assumptions necessary when evidence is absent.

Systematic Literature Review of Economic Evaluations of Biological Treatment Sequences for Patients with Moderate to Severe Rheumatoid Arthritis Previously Treated with Disease-Modifying Anti-rheumatic Drugs.

This systematic literature review (SLR) had two objectives: to analyse published economic evaluations of biological disease-modifying anti-rheumatic drugs (bDMARDs) for patients with moderate to severe rheumatoid arthritis (RA) previously treated with DMARDs and to assess the quality of those that included sequences of treatments. We performed an SLR on PubMed, Central, Cochrane, and French databases from January 2000 to December 2018. The search focused on cost-effectiveness/utility/benefit analyses. We extracted data on treatment sequences, outcomes (e.g. quality-adjusted life year) and choices of economic evaluation methods (e.g. model type, type of analysis, and method of utility estimation). We analysed the improvement of methods by comparing two sub-periods (2000-2009 and 2010-2018). The quality of reporting and the quality of the methods were assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) and a set of eight key aspects for a reference case for economic evaluation of bDMARDs based on the Outcome Measures in Rheumatology (OMERACT) and Drummond checklists. Data extraction and study assessment were performed independently by two health economists. From the 824 records identified in the initial search, 51 publications were selected. Of these, 31 included sequences. Individual models such as discrete-event simulations were used in over two-fifths (22/51, 43%) of the selected studies. Few studies (7/51, 14%) used utility scores based on generic instruments (e.g. EQ-5D). Estimation of hospitalization costs was described in only approximately one-third of studies (19/51). Loss of quality of life (QoL) related to adverse events such as tuberculosis and pneumonia was included in one-tenth (5/51, 10%) of the studies. It was difficult to compare the results of the economic evaluations (i.e. incremental cost-effectiveness ratios) due to the high heterogeneity of studies in terms of disease stage, data sources, inputs, and methods of health outcome assessment used. For identified studies including sequences, the CHEERS assessment of reporting quality showed insufficient reporting of uncertainty analyses and utility weights in more than a third of the studies (11/31, 35%; 9/25, 36%). An in-depth assessment of the quality of the studies revealed that only seven, mostly conducted during the sub-period 2010-2018, addressed the majority of methodological quality assessment issues such as the simulation of patient sequence pathways, the use of systematic reviews and meta-analyses of comparative effectiveness, the choice of treatment sequence, and rules for switching. Our SLR identified a lack of high-quality evaluations assessing bDMARD sequences, although some improvements were made in the reporting and modelling of patients' pathways in studies published after 2010. In order to improve economic evaluations of RA, clear health technology assessment guidance on RA health-related QoL instruments must be provided, and data including long-term disease progression must be made available.

PNS59 INCORPORATING THE PATIENT'S PERSPECTIVE IN ECONOMIC EVALUATIONS OF HEALTHCARE

Patient-centricity has become increasingly important in healthcare. This requires the patient’s perspective (PP) to be considered at all levels of decision making, ranging from coverage/reimbursement to clinical guideline development and shared healthcare decisions. In economic evaluations, different perspectives are reflected in the types of outcomes and costs considered. The objectives of this study are to understand whether and how PP has been incorporated in economic evaluations, to assess the need for more patient-centric economic models, and to propose a framework for better incorporating PP in economic evaluations. A targeted literature review of economic evaluations incorporating PP was performed. The key information on health outcomes and costs, the methods used to measure and value such parameters, and the decisions that the economic evaluations were intended to inform was extracted. Limitations of existing ways of incorporating PP and commentaries on how to fully reflect these were critically reviewed. A framework for better incorporating PP in economic evaluations was proposed. Few economic evaluations included PP, and these were often grouped within a ‘societal’ perspective. Direct health benefits to patients, measured as life-years and quality-adjusted life-years are the most common outcomes estimated; other attributes were not considered, such as convenience, ease of use, or hope for patients and families. Direct medical costs were commonly included as relevant to patients, followed by direct non-medical and indirect costs. Intangible costs were rarely included. Average population or patient preferences were often used, with limited flexibility to account for patient heterogeneity. More patient-centric economic models are needed to reflect PP. An assessment framework using flexible model structures for better incorporating PP was developed. PP can be and should be better incorporated in economic evaluations of health care. This will ensure better informed decision making at all levels of the health care system.

Costs and effectiveness of influenza vaccination: a systematic review.

Seasonal influenza can cause a significant public health burden. Vaccination is proposed as the most effective measure to prevent influenza and related undesired outcomes. To estimate the efficiency of influenza vaccination. A literature review of economic evaluations of influenza vaccinations, published over the last 5 years, was performed using MEDLINE (through PubMed), Web of Science and Scopus. 935 papers were identified and 30 were selected, including studies performed in different population subgroups: general population, children, adults, elderly, pregnant women and high risk patients. Twenty-one studies were performed in Europe and in US. The majority of the studies were carried out on elderly patients and children. All except one were cost-effectiveness analyses and reported influenza vaccination as a cost-saving or cost-effective intervention. Vaccination strategies are economically favourable in a range of countries and sub-groups of patients.

Identifying attributes of care that may improve cost-effectiveness in the youth mental health service system.

To identify attributes of youth mental health care for which there is evidence of potential cost-effectiveness. We performed a literature review of economic evaluations that examined both costs and outcomes for attributes of youth mental health care other than pharmacological or individual psychological therapies for full-threshold disorders. We searched the United Kingdom National Health Service Economic Evaluations Database for evaluations published to the end of 2014; and MEDLINE, Google Scholar and the citation lists of relevant publications for peer-reviewed studies published in English since 1997. Forty economic evaluations met inclusion criteria. Psychosis was the mental disorder with the most developed economic evidence base, with good evidence of cost-effectiveness for first-episode psychosis services. There was a developing cost-effectiveness evidence base for other disorders. The most common attributes of the interventions examined in the included studies were the location of services, engagement and support of families, assessment, prevention, early intervention, group delivery format and information provision. We used our findings to formulate a list of attributes of youth mental health care that may be acceptable to young people and potentially cost-effective. There is at least suggestive cost-effectiveness evidence for a range of attributes of youth mental health care. Further economic research is needed to substantiate most cost-effectiveness findings and to improve targeting of care among young people. Future economic evaluations should examine costs from both societal and health care perspectives and incorporate evidence regarding young people's preferences.

A Systematic Review of Economic Evaluations of Pharmacogenetic Testing for Prevention of Adverse Drug Reactions.

Pharmacogenetics offers the potential to improve health outcomes by identifying individuals who are at greater risk of harm from certain medicines. Routine adoption of pharmacogenetic tests requires evidence of their cost effectiveness. The present review aims to systematically review published economic evaluations of pharmacogenetic tests that aim to prevent or reduce the incidence of ADRs. We conducted a systematic literature review of economic evaluations of pharmacogenetic tests aimed to reduce the incidence of adverse drug reactions. Literature was searched using Embase, MEDLINE and the NHS Economic Evaluation Database with search terms relating to pharmacogenetic testing, adverse drug reactions, economic evaluations and pharmaceuticals. Titles were screened independently by two reviewers. Articles deemed to meet the inclusion criteria were screened independently on abstract, and full texts reviewed. We identified 852 articles, of which 47 met the inclusion criteria. There was evidence supporting the cost effectiveness of testing for HLA-B*57:01 (prior to abacavir), HLA-B*15:02 and HLA-A*31:01 (prior to carbamazepine), HLA-B*58:01 (prior to allopurinol) and CYP2C19 (prior to clopidogrel treatment). Economic evidence was inconclusive with respect to TPMT (prior to 6-mercaptoputine, azathioprine and cisplatin therapy), CYP2C9 and VKORC1 (to inform genotype-guided dosing of coumarin derivatives), MTHFR (prior to methotrexate treatment) and factor V Leiden testing (prior to oral contraception). Testing for A1555G is not cost effective before prescribing aminoglycosides. Our systematic review identified robust evidence of the cost effectiveness of genotyping prior to treatment with a number of common drugs. However, further analyses and (or) availability of robust clinical evidence is necessary to make recommendations for others.

Adjusting for Drug Wastage in Economic Evaluations of New Therapies for Hematologic Malignancies: A Systematic Review.

As costs of cancer care rise, there has been a shift to focus on value. Drug wastage affects costs to patients and health care systems without adding value. Historically, cost-effectiveness analyses have used models that assume no drug wastage; however, this may not reflect real-world practices. We sought to identify the frequency of drug wastage modeling in economic evaluations of modern parenteral therapies for hematologic malignancies. We conducted a systematic literature review of economic evaluations of new US Food and Drug Administration-approved parenteral chemotherapies with indications for the treatment of hematologic malignancies. The primary outcome of interest was the proportion of studies that modeled drug wastage in base-case analyses. If wastage was considered in primary analyses, we reported the impact of wastage on incremental cost-effectiveness ratios (ICERs) and drug acquisition costs. Wastage was considered in base-case analyses in less than one third of all publications reviewed (12 of 38; 32%). Of these, two studies went on to complete sensitivity analyses and reported significant changes in the calculated ICER as a result. In one study, the ICER increased by 32%, and in the second, accounting for wastage changed a positive ICER to a dominant result. Potential costs associated with drug wastage are considered in only one third of modern cost-effectiveness models. The impact of wastage on calculated ICERs and drug acquisition costs is potentially substantial. The modeling of wastage in base-case and sensitivity analyses is recommended for future economic evaluations of new intravenous therapies for hematologic malignancies.

A literature review of economic evaluations for a neglected tropical disease: human African trypanosomiasis ("sleeping sickness").

Human African trypanosomiasis (HAT) is a disease caused by infection with the parasite Trypanosoma brucei gambiense or T. b. rhodesiense. It is transmitted to humans via the tsetse fly. Approximately 70 million people worldwide were at risk of infection in 1995, and approximately 20,000 people across Africa are infected with HAT. The objective of this review was to identify existing economic evaluations in order to summarise cost-effective interventions to reduce, control, or eliminate the burden of HAT. The studies included in the review were compared and critically appraised in order to determine if there were existing standardised methods that could be used for economic evaluation of HAT interventions or if innovative methodological approaches are warranted. A search strategy was developed using keywords and was implemented in January 2014 in several databases. The search returned a total of 2,283 articles. After two levels of screening, a total of seven economic evaluations were included and underwent critical appraisal using the Scottish Intercollegiate Guidelines Network (SIGN) Methodology Checklist 6: Economic Evaluations. Results from the existing studies focused on the cost-effectiveness of interventions for the control and reduction of disease transmission. Modelling was a common method to forecast long-term results, and publications focused on interventions by category, such as case detection, diagnostics, drug treatments, and vector control. Most interventions were considered cost-effective based on the thresholds described; however, the current treatment, nifurtomix-eflornithine combination therapy (NECT), has not been evaluated for cost-effectiveness, and considerations for cost-effective strategies for elimination have yet to be completed. Overall, the current evidence highlights the main components that play a role in control; however, economic evaluations of HAT elimination strategies are needed to assist national decision makers, stakeholders, and key funders. These analyses would be of use, as HAT is currently being prioritized as a neglected tropical disease (NTD) to reach elimination by 2020.

RETRACTED: Systematic Review of Economic Evaluation Literature in Ghana: Is Health Technology Assessment the Future?

In many countries, such as Ghana, there is an increasing impetus to use economic evaluation to allow more explicit and transparent health care priority setting. An important question for policymakers in low-income countries, however, is whether it is possible to introduce economic evaluation data into health care priority-setting decisions. This article systematically reviewed the literature on economic evaluation on medical devices and pharmaceuticals in Ghana published between 1997 and 2012. Its aim was to analyze the quantity, quality, and targeting of economic evaluation studies that relate to medical devices and pharmaceuticals and provide a framework for those conducting similar health technology assessment reviews in similar contexts. The review revealed that the number of publications reporting economic evaluations was minimal with regard to medical devices and pharmaceuticals. With the introduction of the National Health Insurance Scheme since 2004 policymakers are confronted with the challenge of allocating scarce resources rationally. Priority setting therefore has to be guided by a sound knowledge of the costs of providing health services. The need for economic evaluation is thus important. More costing studies were found; there were very few cost-effectiveness analysis studies. If economic evaluation is useful for policymakers only when performed correctly and reported accurately, these findings depict barriers to using economic evaluation to assist decision-making processes in Ghana; hence, there is a need for an independent health technology assessment unit.

Generic Atorvastatin, the Belgian Statin Market and the Cost-Effectiveness of Statin Therapy

This study examines how the market entry of generic atorvastatin influences the Belgian statin market and the cost-effectiveness of statin therapy. Using IMS Health data, the Belgian 2000-2011 statin market was analyzed in terms of total expenditure, annual price of statin treatment, and patient numbers. A simulation analysis projected statin market shares from 2012 to 2015 following market entry of generic atorvastatin. This analysis was based on three scenarios regarding the number of patients taking specific statins. Savings associated with an atorvastatin price reduction of 50-70 % were calculated. A literature review of economic evaluations assessed the cost-effectiveness of generic atorvastatin. Statin expenditure increased from €113 million in 2000 to €285 million in 2011 due to higher expenditure on atorvastatin and rosuvastatin. Although the number of patients treated with simvastatin increased by nearly 800 %, the resulting increase in expenditure was partially offset by price reductions. Atorvastatin is projected to become the dominant product in the Belgian statin market (market share of 47-66 % by 2015). Annual savings would attain €108.6-€153.7 million for a 50 % reduction in the atorvastatin price and €152.0-€215.2 million for a 70 % price reduction. The literature suggests that generic atorvastatin is cost-effective as compared to simvastatin. The limited evidence about the cost-effectiveness of rosuvastatin as compared with generic atorvastatin is inconclusive. Generic atorvastatin is cost-effective as compared to simvastatin, is projected to become the dominant product in the Belgian statin market and is expected to generate substantial savings to health care payers.

Cost Effectiveness of Pharmacotherapies for Attention-Deficit Hyperactivity Disorder

Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disorder that impairs the quality of life for patients and their families and is associated with considerable direct and indirect costs. Pharmacotherapies for ADHD, including stimulants and non-stimulants, are often used to treat patients with ADHD. However, the costs, effectiveness and adverse effects of these agents vary. Therefore, information regarding the cost effectiveness of different pharmacological treatments is needed to better inform payers in the allocation of limited resources. The objectives of this study were to conduct a systematic literature review of economic evaluations of pharmacotherapies for ADHD treatments and to assess the cost effectiveness of different interventions based on the existing studies. A systematic literature review of economic evaluations of pharmacotherapies for ADHD was conducted in MEDLINE, the National Health Services (NHS) Economic Evaluation database and EMBASE. For inclusion in this review, studies had to compare two or more ADHD interventions with at least one pharmacotherapy, assess both costs and outcomes, and be conducted between 1990 and 2011 in North America, Europe, Australia or New Zealand. Studies were excluded if they were not original research, were presented only as conference proceedings or abstracts or did not report costs associated with specific interventions. The study quality was assessed using the British Medical Journal (BMJ) health economics checklist. The literature search, data extraction and quality assessment were performed by one author and independently checked for accuracy by a second author. Discrepancies were resolved by consensus and referring to the original article. If necessary, a third reviewer was consulted. The initial search returned 93 citations from MEDLINE, 10 from the NHS Economic Evaluation database and 377 from EMBASE. Thirteen papers met the inclusion/exclusion criteria and were included in the review. Based on the BMJ checklist, all these studies were considered to be of sufficient quality to be included in the literature review, but they varied substantially in target population, methodology and effectiveness measures. Identified pharmacotherapies were cost effective compared with no treatment, placebo, behavioural therapy or community care among children and adolescents with ADHD. Studies comparing non-stimulants with stimulants and amfetamine with methylphenidate stimulants showed inconsistent findings. A limited number of studies indicated that methylphenidate Osmotic-controlled Release Oral delivery System (OROS) was cost effective compared with short-acting methylphenidate. There were no published studies on the cost effectiveness of pharmacotherapy in the adult ADHD population, comparing stimulants, non-stimulants or adjuvant therapy. There is limited evidence on the long-term cost effectiveness of pharmacotherapies. Among children and adolescents with ADHD, there was consistent evidence that pharmacotherapies are cost effective compared with no treatment or behavioural therapy. Adequate data are lacking to draw conclusions regarding the relative cost effectiveness of different pharmacological agents. More economic evaluations with standardized methods, such as effectiveness measures and cost components, are warranted. To better inform payers about the economic value of existing medications, future studies should also consider identifying subgroups that may have heterogeneous responses to different treatments, including analyses of recently approved treatments (e.g. lisdexamfetamine, guanfacine extended-release and clonidine extended-release) and expanding the time horizon to incorporate long-term outcomes.

Economic Evaluations of Organ Transplantations - A Systematic Literature Review

The purpose of this study is threefold; 1) to establish the current level of knowledge regarding cost-effectiveness of organ transplantation, 2) to identify knowledge gaps, and 3) to suggest a framework for future studies. A systematic literature review of economic evaluations of transplantations of solid organs was conducted in October 2010. Economic evaluations published since 2000 and reviews published since 1987 for kidney, liver, lung, heart, pancreas, and small bowel transplantations were collected. The studies were analysed regarding results and study characteristics. The review demonstrates a lack of economic evaluations for all included organ transplantations. The cost-effectiveness of kidney transplantation, and to some extent liver transplantation, compared to a non-transplant alternative appears to be established. However, cost-effectiveness for transplantation of lung, heart, pancreas, and small bowel can neither be established nor rejected based on earlier studies. Many of the included studies were limited in a number of ways; e.g. using short follow-up period, failing to account for sample selection in treatment groups, comparing to unrealistic alternatives, lacking important cost categories, and using a limiting perspective. Recommendation for future studies are, besides accounting for the above, to conduct sub-group analyses as patient and disease characteristics, among other things, has been shown to affect the cost-effectiveness of organ transplantation.
