Cost Analysis of Noninvasive Blood-Based MicroRNA Testing Versus CT Scans for Follow-up in Patients With Testicular Germ-Cell Tumors.

BACKGROUND: Our group has developed a noninvasive blood-based microRNA (miRNA) test for improving diagnosis, disease monitoring, and relapse detection in malignant testicular germ-cell tumors (TGCTs). Performance analysis suggests the test is likely to have comparable sensitivity and specificity in detecting TGCT as computed tomography (CT), thus reducing the need for serial CT scans for follow-up monitoring, with associated reductions in cumulative radiation burden and second cancer risk. To facilitate clinical adoption, we undertook a cost analysis to identify the budget impact of replacing CT scans with miRNA testing within health care systems. METHODS: The TGCT aftercare pathway was mapped out using National Comprehensive Cancer Network guidelines. A Markov model was built to simulate the impact of the miRNA test on TGCT aftercare costs. Incidence, treatment probabilities, relapse rate, and death rate data were collected from published studies to populate the model. RESULTS: Applying our model to the US health care system, the miRNA test has the potential to save up to $69 million per year in aftercare expenses related to TGCT treatment, with exact savings depending on the adoption rate and test price. CONCLUSION: This analysis demonstrates the potential positive budget impact of adopting miRNA testing in place of CT scans in the clinical management of TGCTs.

Identifying disparities in germline and somatic testing for ovarian cancer.

OBJECTIVE: Germline mutations occur in approximately 25% of patients with epithelial ovarian cancers while somatic BRCA mutations are estimated at 5-7%. The objectives of this study were to determine the rate of germline and somatic testing in women with ovarian cancer and to identify disparities in testing at a comprehensive cancer center (CCC) and a safety net hospital (SNH). METHODS: Patients treated for ovarian cancer from 2011 to 2016 were included. Clinicopathologic data were abstracted from the electronic medical records. Logistic regression modeling were performed to calculate odds ratios (OR) and corresponding 95% confidence intervals (95%CI). RESULTS: Out of 367 women, 55.3% completed germline testing; 27.0% received somatic testing. Women at the CCC were more likely to be tested for germline (60.4% vs 38.1%, p ≤ 0.001) and somatic (34.3% vs 2.4%, p ≤ 0.001) mutations than those at the SNH. Patients with Medicare (aOR = 0.51, 95%CI 0.28-0.94, p = 0.032) or Medicaid (aOR = 0.42, 95%CI 0.18-0.99, p = 0.048) were less likely to receive germline testing than those privately insured. Patients with Medicaid were less likely to receive somatic testing (aOR = 0.15, 95%CI 0.04-0.62, p = 0.009) than those privately insured. Women with disease recurrence had a higher likelihood of being tested for germline (OR = 3.64, 95%CI 1.94-6.83, P < 0.001) and somatic (OR = 7.89, 95%CI 3.41-18.23, p < 0.001) mutations. There was no difference in germline or somatic testing by race/ethnicity. CONCLUSIONS: Disparities in both germline and somatic testing exist. Understanding and overcoming barriers to testing may improve cancer-related mortality by allowing for more tailored treatments as well as for improved cascade testing.

An Evaluation of the Cost-effectiveness of Comprehensive MTM Integrated with Point-of-Care Phenotypic and Genetic Testing for U.S. Elderly Patients After Percutaneous Coronary Intervention.

BACKGROUND: Poor health outcomes after percutaneous coronary intervention (PCI) in elderly patients is an area of concern among policymakers and administrators. In an effort to determine the best strategy to improve outcomes among elderly patients who underwent PCI, several studies have evaluated the cost-effectiveness of genotype-guided antiplatelet therapy compared with universal use of any one of the antiplatelet drugs indicated for patients with acute coronary syndrome (ACS) who underwent PCI. The results have either been in favor of genotype-guided antiplatelet therapy or universal use of ticagrelor. However, no study has yet evaluated the cost-effectiveness of pharmacist-provided face-to-face medication therapy management (MTM) combined with point-of-care genotype-guided antiplatelet therapy (POCP) when compared with universal use of ticagrelor or clopidogrel for the elderly after PCI. OBJECTIVE: To evaluate the cost-effectiveness of a pharmacist integration of MTM with POCP (MTM-POCP) when compared with universal use of ticagrelor or clopidogrel combined with MTM (MTM-ticagrelor or MTM-clopidogrel). METHODS: We conducted a cost-effectiveness analysis from the perspective of the U.S. health care system. A hybrid model, consisting of a 1-year decision tree and a 20-year Markov model, was used to simulate a cohort of elderly patients (aged at least 65 years) with ACS who underwent PCI. Treatment strategies available to patients were POCP, POCP-MTM, MTM-clopidogrel, or MTM-ticagrelor. Data used to populate the model were obtained from the PLATO trial and other published studies. Outcome measures were costs, quality-adjusted life-years (QALYs) and incremental cost per QALY gained. A deterministic and probabilistic sensitivity analysis was conducted to account for the joint uncertainty around the key parameters of the model. Finally, a benchmark willingness to pay of $50,000-200,000 was considered. RESULTS: The use of PCOP (with dual antiplatelet therapy) resulted in 5.29 QALYs, at a cost of $50,207. MTM-clopidogrel resulted in 5.34 QALYs, at a cost of $50,011. The use of POCP-MTM resulted in 5.36 QALYs, at a cost of $50,270. Finally, MTM-ticagrelor resulted in 5.42 QALYs, at a cost of $53,346. MTM-ticagrelor was found to be cost-effective compared with MTM-clopidogrel or MTM-POCP, irrespective of the willingness to pay. The deterministic and probabilistic sensitivity analyses confirmed the robustness of the base-case analysis. CONCLUSIONS: The combination of MTM-ticagrelor was cost-effective when compared with MTM-POCP or MTM-clopidogrel. The transitional probabilities, however, were mostly based on published studies. Analysis based on a prospective randomized clinical study, comparing all the treatment strategies included in this study, is warranted to confirm our findings.

Future Considerations for the Evaluation of Hepatitis C Virus Treatments in Pan-Genotypic Therapy for Noncirrhotic Treatment-Naive Patients.

Given the recent approval of the first pan-genotypic chronic hepatitis C virus (HCV) therapy, managed care, health systems, and clinicians will need to evaluate current practices related to essential laboratory assessments used to select therapy. Historically, clinicians and payers required a battery of tests to determine HCV genotype, viral load, degree of fibrosis, and organ function. In light of current and forthcoming approvals of pan-genotypic therapy, clinicians and payers can expect a more competitive marketplace and a downward curve in the price of therapy. Ultimately, this development will lead to the cost of screenings and assessments having an increased role in selecting an optimal HCV therapy. DISCLOSURES: No outside funding supported this study. The authors have nothing to disclose. All authors contributed to study concept and design. Calabrese took the lead in data collection, along with Shaya. Data interpretation was performed by Calabrese and Hynicka, along with Rodriguez de Bittner and Shaya. The manuscript was written and revised by Calabrese and Hynicka, along with Rodriguez de Bittner and Shaya.

Impacts of Early Guideline-Directed 21-Gene Recurrence Score Testing on Adjuvant Therapy Decision Making.

PURPOSE: The 21-gene recurrence score (RS) assay is used to help formulate adjuvant chemotherapy recommendations for patients with estrogen receptor-positive, early-stage breast cancer. Most frequently, medical oncologists order RS after surgery. Results take an additional 2 weeks to return, which can delay decision making. We conducted a prospective quality-improvement project to assess the impact of early guideline-directed RS ordering by surgeons before the first visit with a medical oncologist on adjuvant therapy decision making. MATERIALS AND METHODS: Surgical oncologists ordered RS testing following National Comprehensive Cancer Network guidelines at time of diagnosis or at time of surgery between July 1, 2015 and December 31, 2015. We measured the testing rate of patients eligible for RS, time to chemotherapy decisions, rates of chemotherapy use, accrual to RS-based clinical trials, cost, and physician acceptance of the policy and compared the results to patients who met eligibility criteria for early guideline-directed testing during the 6 months before the project. RESULTS: Ninety patients met eligibility criteria during the testing period. RS was ordered for 91% of patients in the early testing group compared with 76% of historical controls ( P < .001). Median time to chemotherapy decision was significantly shorter in the early testing group (20 days; 95% CI, 17 to 23 days) compared with historical controls (32 days; 95% CI, 29 to 35 days; P < .001). There were no significant differences in time to chemotherapy initiation, chemotherapy use, RS-based trial enrollment, or calculated costs between the groups. CONCLUSION: Early guideline-directed RS testing in selected patients is an effective way to shorten time to treatment decisions.

Barriers preventing the adoption of comprehensive cancer genomic profiling in the clinic.

INTRODUCTION: Comprehensive cancer genomic profiling provides the opportunity to expose the various molecular aberrations potentially driving tumor progression. Consequently, the identity of these genetic drivers can be utilized to match a patient to the most appropriate targeted therapy, thereby increasing the probability of improved clinical outcome. Despite its capability of informing patient care, the adoption of comprehensive cancer genomic profiling in the clinic has not been widespread. The barriers surrounding its universal acceptance are attributed to both physician and patient perspectives. Areas covered: The following report discusses the various obstacles in place, including those related to clinical utility, education, insurance coverage, and clinical trials, which can deter physicians and patients from utilizing genomic profiling for therapeutic decision-making. Expert commentary: The authors review the recent growth and potential of clinical utility studies over the last two years, provide a suggestive framework for educational support, and comment on the use of social media to enhance clinical trial recruitment.

A Multigene Test Could Cost-Effectively Help Extend Life Expectancy for Women at Risk of Hereditary Breast Cancer.

BACKGROUND: The National Comprehensive Cancer Network recommends that women who carry gene variants that confer substantial risk for breast cancer consider risk-reduction strategies, that is, enhanced surveillance (breast magnetic resonance imaging and mammography) or prophylactic surgery. Pathogenic variants can be detected in women with a family history of breast or ovarian cancer syndromes by multigene panel testing. OBJECTIVES: To investigate whether using a seven-gene test to identify women who should consider risk-reduction strategies could cost-effectively increase life expectancy. METHODS: We estimated effectiveness and lifetime costs from a payer perspective for two strategies in two hypothetical cohorts of women (40-year-old and 50-year-old cohorts) who meet the National Comprehensive Cancer Network-defined family history criteria for multigene testing. The two strategies were the usual test strategy for variants in BRCA1 and BRCA2 and the seven-gene test strategy for variants in BRCA1, BRCA2, TP53, PTEN, CDH1, STK11, and PALB2. Women found to have a pathogenic variant were assumed to undergo either prophylactic surgery or enhanced surveillance. RESULTS: The incremental cost-effectiveness ratio for the seven-gene test strategy compared with the BRCA1/2 test strategy was $42,067 per life-year gained or $69,920 per quality-adjusted life-year gained for the 50-year-old cohort and $23,734 per life-year gained or $48,328 per quality-adjusted life-year gained for the 40-year-old cohort. In probabilistic sensitivity analysis, the seven-gene test strategy cost less than $100,000 per life-year gained in 95.7% of the trials for the 50-year-old cohort. CONCLUSIONS: Testing seven breast cancer-associated genes, followed by risk-reduction management, could cost-effectively improve life expectancy for women at risk of hereditary breast cancer.

Payer Coverage for Hereditary Cancer Panels: Barriers, Opportunities, and Implications for the Precision Medicine Initiative.

Background: Hereditary cancer panels (HCPs), testing for multiple genes and syndromes, are rapidly transforming cancer risk assessment but are controversial and lack formal insurance coverage. We aimed to identify payers' perspectives on barriers to HCP coverage and opportunities to address them. Comprehensive cancer risk assessment is highly relevant to the Precision Medicine Initiative (PMI), and payers' considerations could inform PMI's efforts. We describe our findings and discuss them in the context of PMI priorities. Methods: We conducted semi-structured interviews with 11 major US payers, covering >160 million lives. We used the framework approach of qualitative research to design, conduct, and analyze interviews, and used simple frequencies to further describe findings. Results: Barriers to HCP coverage included poor fit with coverage frameworks (100%); insufficient evidence (100%); departure from pedigree/family history-based testing toward genetic screening (91%); lacking rigor in the HCP hybrid research/clinical setting (82%); and patient transparency and involvement concerns (82%). Addressing barriers requires refining HCP-indicated populations (82%); developing evidence of actionability (82%) and pathogenicity/penetrance (64%); creating infrastructure and standards for informing and recontacting patients (45%); separating research from clinical use in the hybrid clinical-research setting (44%); and adjusting coverage frameworks (18%). Conclusions: Leveraging opportunities suggested by payers to address HCP coverage barriers is essential to ensure patients' access to evolving HCPs. Our findings inform 3 areas of the PMI: addressing insurance coverage to secure access to future PMI discoveries; incorporating payers' evidentiary requirements into PMI's research agenda; and leveraging payers' recommendations and experience to keep patients informed and involved.

Impact of Payer Constraints on Access to Genetic Testing.

BACKGROUND: With increased demand for hereditary cancer genetic testing, some large national health-care insurance payers (LNHPs) have implemented policies to minimize inappropriate testing by mandating consultation with a geneticist or genetic counselor (GC). We hypothesized such a restriction would reduce access and appropriate testing. METHODS: Test cancellation rates (ie, tests ordered that did not result in a reported test result), mutation-positive rates, and turnaround times for comprehensive BRCA1/2 testing for a study LNHP that implemented a GC-mandate policy were determined over the 12 months before and after policy implementation (excluding a 4-month transition period). Cancellation rates were evaluated based on the reason for cancellation, National Comprehensive Cancer Network testing criteria, and self-identified ancestry. A control LNHP was evaluated over the same period for comparison. RESULTS: The study LNHP cancellation rate increased from 13.3% to 42.1% ( P < .001) after policy implementation. This increase was also observed when only individuals who met National Comprehensive Cancer Network criteria for hereditary breast and ovarian cancer testing were considered (9.5% to 37.7%; P < .001). Cancellation rates increased after policy introduction for all ancestries; however, this was more pronounced among individuals of African or Latin American ancestry, for whom cancellation rates rose to 48.9% and 49.6%, respectively, compared with 33.9% for individuals of European ancestry. Over this same time period, control LNHP cancellation rates decreased or stayed the same for all subgroups. CONCLUSION: These findings demonstrate that a GC-mandate policy implemented by a LNHP substantially decreased access to appropriate genetic testing, disproportionately impacting minority populations without any evidence that inappropriate testing was decreased.

Pharmacogenomics Can Enhance Prescribing of Psychiatric Medications.

Many psychiatric patients experience pharmaceutical intolerances, and some of them do not derive optimal efficacy from their pharmacotherapies. Clinical problems such as these may result in prolonged dysfunction, adverse consequences, and repeated changes in medication treatment regimens. Pharmacogenomics is a laboratory method that aids individualized medication selection by predicting drug efficacy and adverse effect profiles. It is a technique that involves the testing of patients' genetic makeup to improve medicinal response and tolerance. Pharmacogenomics aims to clarify pharmacokinetics and pharmacodynamics in addition to focusing on hepatic cytochrome enzyme metabolism. Ultimately, it facilitates optimal selection and adjustment of medications to enhance clinical outcomes. Pharmacogenomics is most useful in cases in which routinely prescribed pharmacotherapies are either suboptimally effective or have unacceptable adverse effects. Once there has been a failure of a therapeutic drug treatment, rather than "blindly" selecting an alternative medicine, pharmacogenomic test results can provide guidance for the selection of the most appropriate drug and its dose. The intent is to yield a greater likelihood of patient success in following a therapeutic intervention.

The diagnostic pathway in complex paediatric neurology: a cost analysis.

BACKGROUND: The diagnostic trajectory of complex paediatric neurology may be long, burdensome, and expensive while its diagnostic yield is frequently modest. Improvement in this trajectory is desirable and might be achieved by innovations such as whole exome sequencing. In order to explore the consequences of implementing them, it is important to map the current pathway. To that end, this study assessed the healthcare resource use and associated costs in this diagnostic trajectory in the Netherlands. METHODS: Fifty patients presenting with complex paediatric neurological disorders of a suspected genetic origin were included between September 2011 and March 2012. Data on their healthcare resource utilization were collected from the hospital medical charts. Unit prices were obtained from the Dutch Healthcare Authority, the Dutch Healthcare Insurance Board, and the financial administration of the hospital. Bootstrap simulations were performed to determine mean quantities and costs. RESULTS: The mean duration of the diagnostic trajectory was 40 months. A diagnosis was established in 6% of the patients. On average, patients made 16 physician visits, underwent four imaging and two neurophysiologic tests, and had eight genetic and 16 other tests. Mean bootstrapped costs per patient amounted to €12,475, of which 43% was for genetic tests (€5,321) and 25% for hospital visits (€3,112). CONCLUSION: Currently, the diagnostic trajectories of paediatric patients who have complex neurological disease with a strong suspected genetic component are lengthy, resource-intensive, and low-yield. The data from this study provide a backdrop against which the introduction of novel techniques such as whole exome sequencing should be evaluated.

Implementation of modern therapy approaches and research for non-small cell lung cancer in Japan.

The genetic backgrounds of the Japanese (or Asians) are, at least in part, different from those of Caucasians. It is necessary to recognize this difference to develop medicine that is both optimized and individualized. In particular, the consideration of ethnic differences is becoming increasingly important for lung cancer medicine. Japanese clinical practice guidelines indicate that some clinical biomarkers, such as epidermal growth factor receptor gene mutations, echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase fusion gene and uridine diphosphate glucuronosyltransferase genotypes should be determined in appropriate lung cancer patients. At the present time, tests for these biomarkers are covered by the Japanese national health-care programme, as is treatment with certain targeted drugs and cytotoxic agents. Therefore, most patients with lung cancer in Japan receive these tests as part of daily practice if their performance status and organ function are judged to be eligible. In addition, ethnic differences in bone marrow toxicity caused by cytotoxic drugs are reflected in treatment choice, and the requirements for the development of treatment modalities suitable for rare targeted populations are also increasing. To meet these requirements, many collaborative groups in Japan that have improved their infrastructure for investigator-initiated trials and conducted important activities need to provide further optimal treatment modalities for Japanese and Asian patients with lung cancer. Here, the characteristics of lung cancer in Japanese patients, general aspects of medical treatment and the care system in Japan, and representative studies on lung cancer in Japan are reviewed.

A new ethical landscape of prenatal testing: individualizing choice to serve autonomy and promote public health: a radical proposal.

A new landscape of prenatal testing (PNT) is presently developing, including new techniques for risk-reducing, non-invasive sampling of foetal DNA and drastically enhanced possibilities of what may be rapidly and precisely analysed, surrounded by a growing commercial genetic testing industry and a general trend of individualization in healthcare policies. This article applies a set of established ethical notions from past debates on PNT for analysing PNT screening-programmes in this new situation. While some basic challenges of PNT stay untouched, the new development supports a radical individualization of how PNT screening is organized. This reformation is, at the same time, difficult to reconcile with responsible spending of resources in a publicly funded healthcare context. Thus, while the ethical imperative of individualization holds and applies to PNT, the new landscape of PNT provides reasons to start rolling back the type of mass-screening programmes currently established in many countries. Instead, more limited offers are suggested, based on considerations of severity of conditions and optimized to simultaneously serve reproductive autonomy and public health within an acceptable frame of priorities. The new landscape of PNT furthermore underscores the ethical importance of supporting and including people with disabilities. For the very same reason, no ban on what may be analysed using PNT in the new landscape should be applied, although private offers must, of course, conform to strict requirements of respecting reproductive autonomy and what that means in terms of counselling.

Prenatal screening: an ethical agenda for the near future.

Prenatal screening for foetal abnormalities such as Down's syndrome differs from other forms of population screening in that the usual aim of achieving health gains through treatment or prevention does not seem to apply. This type of screening leads to no other options but the choice between continuing or terminating the pregnancy and can only be morally justified if its aim is to provide meaningful options for reproductive choice to pregnant women and their partners. However, this aim should not be understood as maximizing reproductive choice per se. Only if understood as allowing prospective parents to avoid suffering related to living with (a child with) serious disorders and handicaps can prenatal screening be a publicly or collectively funded programme. The alternative of moving prenatal testing outside the healthcare system into the private sector is problematic, as it makes these tests accessible only to those who can afford to pay for it. New developments in prenatal screening will have to be assessed in terms of whether and to what extent they either contribute to or undermine the stated aim of providing meaningful options for reproductive choice. In the light of this criterion, this article discusses the introduction of the new non-invasive prenatal test (NIPT), the tendency to widen the scope of follow-up testing, as well as the possible future scenarios of genome-wide screening and 'prenatal personalised medicine'. The article ends with recommendations for further debate, research and analysis.

Cost-effectiveness analysis of carrier and prenatal genetic testing for X-linked hemophilia.

BACKGROUND/PURPOSE: Hemophilia involves a lifelong burden from the perspective of the patient and the entire healthcare system. Advances in genetic testing provide valuable information to hemophilia-affected families for family planning. The aim of this study was to analyze the cost-effectiveness of carrier and prenatal genetic testing in the health-economic framework in Taiwan. METHODS: A questionnaire was developed to assess the attitudes towards genetic testing for hemophilia. We modeled clinical outcomes of the proposed testing scheme by using the decision tree method. Incremental cost-effectiveness analysis was conducted, based on data from the National Health Insurance (NHI) database and a questionnaire survey. RESULTS: From the NHI database, 1111 hemophilic patients were identified and required an average medical expenditure of approximately New Taiwan (NT) $2.1 million per patient-year in 2009. By using the decision tree model, we estimated that 26 potential carriers need to be tested to prevent one case of hemophilia. At a screening rate of 79%, carrier and prenatal genetic testing would cost NT $85.9 million, which would be offset by an incremental saving of NT $203 million per year by preventing 96 cases of hemophilia. Assuming that the life expectancy for hemophilic patients is 70 years, genetic testing could further save NT $14.2 billion. Higher screening rates would increase the savings for healthcare resources. CONCLUSION: Carrier and prenatal genetic testing for hemophilia is a cost-effective investment in healthcare allocation. A case management system should be integrated in the current practice to facilitate patient care (e.g., collecting family pedigrees and providing genetic counseling).

Effect of enhanced information, values clarification, and removal of financial barriers on use of prenatal genetic testing: a randomized clinical trial.

IMPORTANCE: Prenatal genetic testing guidelines recommend providing patients with detailed information to allow informed, preference-based screening and diagnostic testing decisions. The effect of implementing these guidelines is not well understood. OBJECTIVE: To analyze the effect of a decision-support guide and elimination of financial barriers to testing on use of prenatal genetic testing and decision making among pregnant women of varying literacy and numeracy levels. DESIGN, SETTING, AND PARTICIPANTS: Randomized trial conducted from 2010-2013 at prenatal clinics at 3 county hospitals, 1 community clinic, 1 academic center, and 3 medical centers of an integrated health care delivery system in the San Francisco Bay area. Participants were English- or Spanish-speaking women who had not yet undergone screening or diagnostic testing and remained pregnant at 11 weeks' gestation (n = 710). INTERVENTIONS: A computerized, interactive decision-support guide and access to prenatal testing with no out-of-pocket expense (n = 357) or usual care as per current guidelines (n = 353). MAIN OUTCOMES AND MEASURES: The primary outcome was invasive diagnostic test use, obtained via medical record review. Secondary outcomes included testing strategy undergone, and knowledge about testing, risk comprehension, and decisional conflict and regret at 24 to 36 weeks' gestation. RESULTS: Women randomized to the intervention group, compared with those randomized to the control group, were less likely to have invasive diagnostic testing (5.9% vs 12.3%; odds ratio [OR], 0.45 [95% CI, 0.25-0.80]) and more likely to forgo testing altogether (25.6% vs 20.4%; OR, 3.30 [95% CI, 1.43-7.64], reference group screening followed by invasive testing). Women randomized to the intervention group also had higher knowledge scores (9.4 vs 8.6 on a 15-point scale; mean group difference, 0.82 [95% CI, 0.34-1.31]) and were more likely to correctly estimate the amniocentesis-related miscarriage risk (73.8% vs 59.0%; OR, 1.95 [95% CI, 1.39-2.75]) and their estimated age-adjusted chance of carrying a fetus with trisomy 21 (58.7% vs 46.1%; OR, 1.66 [95% CI, 1.22-2.28]). Significant differences did not emerge in decisional conflict or regret. CONCLUSIONS AND RELEVANCE: Full implementation of prenatal testing guidelines using a computerized, interactive decision-support guide in the absence of financial barriers to testing resulted in less test use and more informed choices. If validated in additional populations, this approach may result in more informed and preference-based prenatal testing decision making and fewer women undergoing testing.

Impact of age cutoffs on a lynch syndrome screening program.

PURPOSE: To determine the impact of applying an age cutoff to tumor-based Lynch syndrome (LS) screening, specifically focusing on changes in relative effectiveness, efficiency, and cost. The project was undertaken to answer questions about implementation of the LS screening program in an integrated health care delivery system. PATIENTS AND METHODS: Clinical data extracted from an internal cancer registry, previous modeling efforts, published literature, and gray data were used to populate decision models designed to answer questions about the impact of age cutoffs in LS screening. Patients with colorectal cancer (CRC) were stratified at 10-year intervals from ages 50 to 80 years and compared with no age cutoff. Outcomes are reported for a cohort of 325 patients screened and includes total cost to screen, LS cases present in the cutoff category, number of LS cases expected to be identified by screening, cost per LS case detected, and total number and percentage of LS cases missed. CONCLUSION: Applying an age cutoff to an LS screening program has considerable potential for decreasing total screening costs and increasing efficiency, but at a loss of effectiveness. Imposing an age cutoff of 50 years reduces the cost of the screening program to 16% of a program with no age cutoff, but at the expense of missing more than half of the cases. Failure to identify LS cases is magnified by a cascade effect in family members. The results of this analysis influenced the final policy in our system.

'A morass of considerations': exploring attitudes towards ethnicity-based haemoglobinopathy-carrier screening in primary care.

BACKGROUND: The Netherlands does not have a national haemoglobinopathy (HbP)-carrier screening programme aimed at facilitating informed reproductive choice. HbP-carrier testing for those at risk is at best offered on the basis of anaemia. Registration of ethnicity has proved controversial and may complicate the introduction of a screening programme if based on ethnicity. However, other factors may also play a role. OBJECTIVE: To explore perceived barriers and attitudes among GPs and midwives regarding the registration of ethnicity and ethnicity-based HbP-carrier screening. METHODS: Six focus groups in Dutch primary care, with a total of 37 GPs (n = 9) and midwives (n = 28) were conducted, transcribed and content analysed using Atlas-ti. RESULTS: Both GPs and midwives struggled with correctly identifying ethnicities at risk for HbP. Ethical concerns regarding privacy seemed to originate from World War II experiences, when ethnic and religious registration facilitated deportation of Jewish citizens, coupled with the political climate at the time focus groups were held. Some respondents thought the ethnicity question might undermine the relationship with their clients. Software programmes prevented GPs from registering ethnicity of patients at risk. Financial implications for patients were also a concern. Despite this, respondents seemed positive about screening and were familiar with identifying ethnicity and used this for individual patient care. CONCLUSIONS: Although health professionals are generally positive about screening, ethical, financial and practical issues surrounding ethnicity-based HbP-carrier screening need to be clarified before introducing such a programme. Primary care professionals can be targeted through professional organizations but they need national policy support.

Cost effectiveness of targeted high-dose atorvastatin therapy following genotype testing in patients with acute coronary syndrome.

BACKGROUND: Results from the PROVE IT trial suggest that patients with acute coronary syndrome (ACS) treated with atorvastatin 80 mg/day (A80) have significantly lower rates of cardiovascular events compared with patients treated with pravastatin 40 mg/day (P40). In a genetic post hoc substudy of the PROVE IT trial, the rate of event reduction was greater in carriers of the Trp719Arg variant in kinesin family member 6 protein (KIF6) than in noncarriers. We assessed the cost effectiveness of testing for the KIF6 variant followed by targeted statin therapy (KIF6 Testing) versus not testing patients (No Test) and treating them with P40 or A80 in the USA from a payer perspective. METHODS: A Markov model was developed in which 2-year event rates from PROVE IT were extrapolated over a lifetime horizon. Costs and utilities were derived from published literature. All costs were in 2010 US dollars except the cost of A80, which was in 2012 US dollars because the generic formulation was available in 2012. Expected costs and quality-adjusted life-years (QALYs) were estimated for each strategy over a lifetime horizon. RESULTS: Lifetime costs were US$31,700; US$37,100 and US$41,300 for No Test P40, KIF6 Testing and No Test A80 strategies, respectively. The No Test A80 strategy was associated with more QALYs (9.71) than the KIF6 Testing (9.69) and No Test P40 (9.57) strategies. No Test A80 had an incremental cost-effectiveness ratio (ICER) of US$232,100 per QALY gained compared with KIF6 Testing. KIF6 Testing had an ICER of US$45,300 per QALY compared with No Test P40. CONCLUSIONS: Testing ACS patients for KIF6 carrier status may be a cost-effective strategy at commonly accepted thresholds. Treating all patients with A80 is more expensive than treating patients on the basis of KIF6 results, but the modest gain in QALYs is achieved at a cost/QALY that is generally considered unacceptable compared with the KIF6 Testing strategy. Compared with treating all patients with P40, the KIF6 Testing strategy had an ICER below US$50,000 per QALY. The conclusions from this study are sensitive to the price of generic A80 and the effect on adherence of knowing KIF6 carrier status. The results were based on a post hoc substudy of the PROVE IT trial, which was not designed to test the effectiveness of KIF6 testing.

Cost-effectiveness analysis of screening for KRAS and BRAF mutations in metastatic colorectal cancer.

BACKGROUND: In 2009, the American Society of Clinical Oncology recommended that patients with metastatic colorectal cancer (mCRC) who are candidates for anti-epidermal growth factor receptor (EGFR) therapy have their tumors tested for KRAS mutations because tumors with such mutations do not respond to anti-EGFR therapy. Limiting anti-EGFR therapy to those without KRAS mutations will reserve treatment for those likely to benefit while avoiding unnecessary costs and harm to those who would not. Similarly, tumors with BRAF genetic mutations may not respond to anti-EGFR therapy, though this is less clear. Economic analyses of mutation testing have not fully explored the roles of alternative therapies and resection of metastases. METHODS: This paper is based on a decision analytic framework that forms the basis of a cost-effectiveness analysis of screening for KRAS and BRAF mutations in mCRC in the context of treatment with cetuximab. A cohort of 50 000 patients with mCRC is simulated 10 000 times, with attributes randomly assigned on the basis of distributions from randomized controlled trials. RESULTS: Screening for both KRAS and BRAF mutations compared with the base strategy (of no anti-EGFR therapy) increases expected overall survival by 0.034 years at a cost of $22 033, yielding an incremental cost-effectiveness ratio of approximately $650 000 per additional year of life. Compared with anti-EGFR therapy without screening, adding KRAS testing saves approximately $7500 per patient; adding BRAF testing saves another $1023, with little reduction in expected survival. CONCLUSIONS: Screening for KRAS and BFAF mutation improves the cost-effectiveness of anti-EGFR therapy, but the incremental cost effectiveness ratio remains above the generally accepted threshold for acceptable cost effectiveness ratio of $100 000/quality adjusted life year.
