HIT-It or Quit It: Heparin-Induced Thrombocytopenia Testing Appropriateness Using 4T Scoring and Inappropriate Testing Cost Analysis.

OBJECTIVES: The American Society of Hematology's 4T scoring system is a validated tool to assess a patient's probability of having heparin-induced thrombocytopenia (HIT) before testing is performed. There is no benefit to testing patients with a low probability 4T score for HIT. This study aimed to assess for inappropriate HIT testing at our institution based on 4T scoring. METHODS: We retrospectively reviewed 201 patient charts and calculated 4T scores and testing costs to assess for inappropriate testing and the economic impact of such testing. RESULTS: HIT testing often occurred in the least appropriate patients and resulted in tens of thousands of dollars of waste for unnecessary testing. CONCLUSIONS: Inappropriate testing for HIT is still a prevalent issue despite literature supporting the 4T score for guidance in testing appropriateness.

Evidence-Based Medicine in Otolaryngology Part 10: Cost-Effectiveness Analyses in Otolaryngology.

Clinicians seek to pursue the most clinically effective treatment strategies, but costs have also become a key determinant in contemporary health care. Economic analyses have thus emerged as a valuable resource to both quantify and qualify the value of existing and emerging interventions and programs. Cost-effectiveness analyses estimate the benefits gained per monetary unit, providing insights to guide resource allocation. Herein, we delineate the related concepts and considerations to facilitate understanding and appraisal of these analyses, so as to better inform the stakeholders in our otolaryngology community.

Mixed-method approaches to strengthen economic evaluations in implementation research.

BACKGROUND: Guidance from economic evaluations on which implementation strategies represent the best return on investment will be critical to advancing the Triple Aim of health care: improving patient care and population health while minimizing per-capita cost. The results of traditional (quantitative) economic evaluations are limited by a remaining "qualitative residual" of contextual information and stakeholders perspectives, which cannot be captured by monetary values alone and is particularly prevalent in implementation science research. The emergence of qualitative methods for economic evaluation offers a promising solution. MAIN BODY: To maximize the contributions of economic evaluations to implementation science, we recommend that researchers embrace a mixed-methods research agenda that merges traditional quantitative approaches with innovative, contextually grounded qualitative methods. Such studies are exceedingly rare at present. To assist implementation scientists in making use of mixed methods in this research context, we present an adapted taxonomy of mixed-method studies relevant to economic evaluation. We then illustrate the application of mixed methods in a recently completed cost-effectiveness evaluation, making use of an adapted version of reporting standards for economic evaluations. CONCLUSIONS: By incorporating qualitative methods, implementation researchers can enrich their economic evaluations with detailed, context-specific information that tells the full story of the costs and impacts of implementation. We end by providing suggestions for building a research agenda in mixed-method economic evaluation, along with more resources and training to support investigators who wish to answer our call to action.

Cost-effectiveness analysis of cochlear dose reduction by proton beam therapy for medulloblastoma in childhood.

BACKGROUND: The aim of this study is to evaluate the cost-effectiveness of proton beam therapy with cochlear dose reduction compared with conventional X-ray radiotherapy for medulloblastoma in childhood. METHODS: We developed a Markov model to describe health states of 6-year-old children with medulloblastoma after treatment with proton or X-ray radiotherapy. The risks of hearing loss were calculated on cochlear dose for each treatment. Three types of health-related quality of life (HRQOL) of EQ-5D, HUI3 and SF-6D were used for estimation of quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) for proton beam therapy compared with X-ray radiotherapy was calculated for each HRQOL. Sensitivity analyses were performed to model uncertainty in these parameters. RESULTS: The ICER for EQ-5D, HUI3 and SF-6D were $21 716/QALY, $11 773/QALY, and $20 150/QALY, respectively. One-way sensitivity analyses found that the results were sensitive to discount rate, the risk of hearing loss after proton therapy, and costs of proton irradiation. Cost-effectiveness acceptability curve analysis revealed a 99% probability of proton therapy being cost effective at a societal willingness-to-pay value. CONCLUSIONS: Proton beam therapy with cochlear dose reduction improves health outcomes at a cost that is within the acceptable cost-effectiveness range from the payer's standpoint.

Use and misuse of cost-effectiveness terminology in the gastroenterology literature: a systematic review.

OBJECTIVES: The increased popularity of economic analyses for evaluating medical interventions has given rise to concern about the rigor with which economic constructs and terminology are used. True cost-effectiveness analysis considers both the costs and outcomes of alternative interventions. A systematic review of the gastroenterology literature was undertaken to evaluate how appropriately cost-effectiveness is assessed. METHODS: A structured MEDLINE search identified all studies published in major gastroenterology journals between 1980 and 1998 that claimed in their abstracts to have assessed the cost-effectiveness of an intervention. Blinded copies of eligible studies were assessed by two independent reviewers who used standard criteria to evaluate the use of economic terminology and key economic constructs. Discrepancies were resolved by consensus. Studies met a "broad criterion" for appropriateness by evaluating both costs and effects and a "strict criterion" by demonstrating dominance of one strategy or considering both incremental costs and incremental effects. RESULTS: Of 110 eligible studies, 77 (70.0%) met the broad criterion and 62 (56.4%) met the strict criterion for appropriateness. This did not seem to vary with either journal impact factor or publication year. Only eight of 18 studies reporting an incremental cost-effectiveness ratio compared its value to an external standard. Few studies explicitly stated their analytic perspective, and a minority of those with time horizons longer than 1 yr had discounted future costs or effects. CONCLUSIONS: Although most studies seem to use cost-effectiveness terminology well, there remains room to improve the rigor with which economic terminology and constructs are applied.

Economic analysis in dermatology.

Cost-effectiveness studies are rising in importance as means for justifying expenditures on health interventions and as guides for making treatment and resource allocation decisions. However, the term "cost-effective" often is used erroneously, attributed to therapies that have not been subjected to rigorous cost analysis or comparison to an appropriate alternative. Health economic studies include cost-of-illness, cost-minimization, cost-effectiveness, cost-utility, and cost-benefit analyses. Each of these types of analyses differs in what it measures and under what circumstances its use is appropriate. This article describes the different types of economic studies, using examples to highlight their key features, and provides a summary of the key components of an economic analysis including perspective, cost and outcomes measurement, time horizon, cost-discounting, and sensitivity analysis.

The benefits and costs of continuing professional development (CPD) for general dental practice: a discussion.

This paper sets out the benefits and costs of continuing professional development (CPD) for general dental practice. These considerations are important in evaluating CPD yet they are rarely formally assessed. This paper draws on literature specifically on dentistry but also from across the medical profession and the economics of education and training. First, the costs of CPD are itemised with some suggestions as to how costs may be reduced. Second, the benefits are identified and the (limited) evidence on the value of CPD is surveyed. Finally, reasons why some GDPs might not undertake sufficient or appropriate CPD are explored and the need for guidance for dental practitioners is identified.

Potential inconsistencies between cost-effectiveness and cost-utility analyses. An upstairs/downstairs socioeconomic distinction.

This paper indicates that certain economic evaluation methods (cost-effectiveness and cost-utility analyses) may yield inconsistent results. Along with the lack of formal grounding of these methods in economic "first principles," this finding suggests the possible benefit of greater reliance on the more formally developed method of cost-benefit analysis.
