Risk of myocarditis and pericarditis after the COVID-19 mRNA vaccination in the USA: a cohort study in claims databases.

BACKGROUND: Several passive surveillance systems reported increased risks of myocarditis or pericarditis, or both, after COVID-19 mRNA vaccination, especially in young men. We used active surveillance from large health-care databases to quantify and enable the direct comparison of the risk of myocarditis or pericarditis, or both, after mRNA-1273 (Moderna) and BNT162b2 (Pfizer-BioNTech) vaccinations. METHODS: We conducted a retrospective cohort study, examining the primary outcome of myocarditis or pericarditis, or both, identified using the International Classification of Diseases diagnosis codes, occurring 1-7 days post-vaccination, evaluated in COVID-19 mRNA vaccinees aged 18-64 years using health plan claims databases in the USA. Observed (O) incidence rates were compared with expected (E) incidence rates estimated from historical cohorts by each database. We used multivariate Poisson regression to estimate the adjusted incidence rates, specific to each brand of vaccine, and incidence rate ratios (IRRs) comparing mRNA-1273 and BNT162b2. We used meta-analyses to pool the adjusted incidence rates and IRRs across databases. FINDINGS: A total of 411 myocarditis or pericarditis, or both, events were observed among 15 148 369 people aged 18-64 years who received 16 912 716 doses of BNT162b2 and 10 631 554 doses of mRNA-1273. Among men aged 18-25 years, the pooled incidence rate was highest after the second dose, at 1·71 (95% CI 1·31 to 2·23) per 100 000 person-days for BNT162b2 and 2·17 (1·55 to 3·04) per 100 000 person-days for mRNA-1273. The pooled IRR in the head-to-head comparison of the two mRNA vaccines was 1·43 (95% CI 0·88 to 2·34), with an excess risk of 27·80 per million doses (-21·88 to 77·48) in mRNA-1273 recipients compared with BNT162b2. INTERPRETATION: An increased risk of myocarditis or pericarditis was observed after COVID-19 mRNA vaccination and was highest in men aged 18-25 years after a second dose of the vaccine. However, the incidence was rare. These results do not indicate a statistically significant risk difference between mRNA-1273 and BNT162b2, but it should not be ruled out that a difference might exist. Our study results, along with the benefit-risk profile, continue to support vaccination using either of the two mRNA vaccines. FUNDING: US Food and Drug Administration.

ISPOR, the FDA, and the Evolving Regulatory Science of Medical Device Products.

The International Society for Pharmacoeconomics and Outcomes Research (ISPOR) is a key venue for members from private industry, government, and academia to collaborate and share advances in regulatory, clinical, and reimbursement science for drugs, devices, and diagnostics. In parallel, the US Food and Drug Administration (FDA) "is responsible for advancing the public health by helping to speed innovations that make medical products more effective, safer, and more affordable." In 2012, the Medical Device Innovation Consortium (MDIC) was formed as a public-private partnership bringing together government, industry, and nonprofit organizations to advance approaches that promote patient access to safe, innovative medical technologies. With a focus on regulatory science, the MDIC has been assessing how to apply real-world evidence (RWE) regulatory science to medical devices. A key goal of this project is to review the history of RWE regulatory science, define terms, and explain why and how RWE is being considered across the total product life cycle, including regulatory assessment. Unique considerations of real-world data for in vitro diagnostics are also taken into account. We envision that these activities will help ensure a high level of rigor and integrity of RWE necessary for regulatory use cases and demonstrate where RWE can be successfully used for regulatory decision making. The ISPOR, FDA, and MDIC are providing the needed leadership in ensuring that diverse stakeholders share a meaningful voice in determining RWE use and, by so doing, are improving the quality and efficiency of care, enhancing health outcomes, and addressing broader societal concerns of reducing health disparities and costs.

Reconstruction of Temporal Hollowing Defect With Anterior-Lateral Thigh Free Flap Following Resection of Recurrent Ameloblastoma of the Infratemporal Fossa and Right Mandible (a Case Report).

Recurrent invasive ameloblastoma of the infratemporal fossa is an uncommonly encountered phenomenon in the practice of oral and maxillofacial surgery and presents many surgical challenges for the practitioner. This case report describes a patient who underwent previous resection of a mandibular ameloblastoma with multiple recurrences. The patient was diagnosed with a recurrent ameloblastoma of the infratemporal fossa that was subsequently resected and reconstructed using an anterolateral thigh (ALT) free tissue transfer. There are few reported cases of recurrent ameloblastomas in the infratemporal fossa and none that describe surgical resection and reconstruction of such a lesion. Owing to the uniqueness of the surgical defect, an ALT flap was used to correct the temporal hollowing. There have been multiple reported cases of reconstruction of temporal hollowing defects using autogenous fat or allograft; however, none have described the use of a de-epithelialized ALT microvascular reconstruction of a temporal hollowing defect. This case report describes a unique clinical situation of surgical resection and reconstruction that resulted in a satisfactory outcome for the patient.

The clinical and economic implications of specimen provenance complications in diagnostic prostate biopsies.

PURPOSE: Inaccurate diagnoses of prostate cancer can result from transposition or contamination of patient biopsy specimens, which are known as specimen provenance complications. We assessed the clinical and economic burden of specimen provenance complications in prostate biopsies in the United States. MATERIALS AND METHODS: We performed a comprehensive, systematic review of the literature to approximate the effect of specimen provenance complications on direct medical costs, patient QALYs and medicolegal costs. Data were extracted from published studies on specimen provenance complications rates, prostate cancer treatment efficacy, treatment cost, litigation/settlement costs after false diagnoses of prostate biopsies and patient quality of life. Sensitivity analysis was done to identify factors that most influenced the outcomes and assess the robustness of the findings. RESULTS: Of the estimated 806,251 primary and secondary prostate biopsies performed annually in the United States 20,322 specimen provenance complications were projected to result in 4,570 clinically meaningful false diagnoses and an expected loss of 634 QALYs. The total burden of specimen provenance complications was projected to exceed $879.9 million or $3,776 per positive cancer diagnosis. This estimate was most sensitive to the indemnity cost per false-positive case and the rate of transpositions at independent reference laboratories. CONCLUSIONS: The societal burden of specimen provenance complications in patients who undergo prostate biopsy exceeds $880 million annually in the United States. This analysis framework may be useful as policy makers, health organizations and researchers seek to decrease false diagnoses of prostate cancer and the consequent effects of delayed or unnecessary treatment. Further study is warranted to quantify the economic burden among additional diseases.

Outcomes and costs of incorporating a multibiomarker disease activity test in the management of patients with rheumatoid arthritis.

OBJECTIVE: The multibiomarker disease activity (MBDA) blood test has been clinically validated as a measure of disease activity in patients with RA. We aimed to estimate the effect of the MBDA test on physical function for patients with RA (based on HAQ), quality-adjusted life years and costs over 10 years. METHODS: A decision analysis was conducted to quantify the effect of using the MBDA test on RA-related outcomes and costs to private payers and employers. Results of a clinical management study reporting changes to anti-rheumatic drug recommendations after use of the MBDA test informed clinical utility. The effect of treatment changes on HAQ was derived from 5 tight-control and 13 treatment-switch trials. Baseline HAQ scores and the HAQ score relationship with medical costs and quality of life were derived from published National Data Bank for Rheumatic Diseases data. RESULTS: Use of the MBDA test is projected to improve HAQ scores by 0.09 units in year 1, declining to 0.02 units after 10 years. Over the 10 year time horizon, quality-adjusted life years increased by 0.08 years and costs decreased by US$457 (cost savings in disability-related medical costs, US$659; in productivity costs, US$2137). The most influential variable in the analysis was the effect of the MBDA test on clinician treatment recommendations and subsequent HAQ changes. CONCLUSION: The MBDA test aids in the assessment of disease activity in patients with RA by changing treatment decisions, improving the functional status of patients and cost savings. Further validation is ongoing and future longitudinal studies are warranted.

Effect of a genomic classifier test on clinical practice decisions for patients with high-risk prostate cancer after surgery.

OBJECTIVES: To evaluate the impact of a genomic classifier (GC) test for predicting metastasis risk after radical prostatectomy (RP) on urologists' decision-making about adjuvant treatment of patients with high-risk prostate cancer. SUBJECTS AND METHODS: Patient case history was extracted from the medical records of each of the 145 patients with pT3 disease or positive surgical margins (PSMs) after RP treated by six high-volume urologists, from five community practices. GC results were available for 122 (84%) of these patients. US board-certified urologists (n = 107) were invited to provide adjuvant treatment recommendations for 10 cases randomly drawn from the pool of patient case histories. For each case, the study participants were asked to make an adjuvant therapy recommendation without (clinical variables only) and with knowledge of the GC test results. Recommendations were made without knowledge of other participants' responses and the presentation of case histories was randomised to minimise recall bias. RESULTS: A total of 110 patient case histories were available for review by the study participants. The median patient age was 62 years, 71% of patients had pT3 disease and 63% had PSMs. The median (range) 5-year predicted probability of metastasis by the GC test for the cohort was 3.9 (1-33)% and the GC test classified 72% of patients as having low risk for metastasis. A total of 51 urologists consented to the study and provided 530 adjuvant treatment recommendations without, and 530 with knowledge of the GC test results. Study participants performed a mean of 130 RPs/year and 55% were from community-based practices. Without GC test result knowledge, observation was recommended for 57% (n = 303), adjuvant radiation therapy (ART) for 36% (n = 193) and other treatments for 7% (n = 34) of patients. Overall, 31% (95% CI: 27-35%) of treatment recommendations changed with knowledge of the GC test results. Of the ART recommendations without GC test result knowledge, 40% (n = 77) changed to observation (95% CI: 33-47%) with this knowledge. Of patients recommended for observation, 13% (n = 38 [95% CI: 9-17%]) were changed to ART with knowledge of the GC test result. Patients with low risk disease according to the GC test were recommended for observation 81% of the time (n = 276), while of those with high risk, 65% were recommended for treatment (n = 118; P < 0.001). Treatment intensity was strongly correlated with the GC-predicted probability of metastasis (P < 0.001) and the GC test was the dominant risk factor driving decisions in multivariable analysis (odds ratio 8.6, 95% CI: 5.3-14.3%; P < 0.001). CONCLUSIONS: Knowledge of GC test results had a direct effect on treatment strategies after surgery. Recommendations for observation increased by 20% for patients assessed by the GC test to be at low risk of metastasis, whereas recommendations for treatment increased by 16% for patients at high risk of metastasis. These results suggest that the implementation of genomic testing in clinical practice may lead to significant changes in adjuvant therapy decision-making for high-risk prostate cancer.

Cost-Effectiveness of Florbetapir-PET in Alzheimer's Disease: A Spanish Societal Perspective.

BACKGROUND: The rising prevalence of Alzheimer's disease (AD), and other diseases associated with dementia, imposes significant burden to various stakeholders who care for the elderly. Management of AD is complicated by multiple factors including disease-specific features which make it difficult to diagnose accurately during milder stages. Florbetapir F18 positron emission tomography (florbetapir-PET) is an approved imaging tool used to capture beta-amyloid neuritic plaque density in brains of cognitively impaired adults undergoing evaluation for AD and other causes of cognitive impairment. It has the potential to help improve healthcare outcomes as it may help clinicians identify patients with AD early so that treatments are initiated when most effective. AIMS OF THE STUDY: Evaluate the potential long-term clinical and economic outcomes of adopting florbetapir-PET--adjunctive to standard clinical evaluation (SCE)--versus SCE alone in the diagnostic assessment of cognitively impaired patients with suspected AD. METHODS: A decision analysis with a ten-year time horizon was developed in compliance with Good Research Practices and CHEERS guidelines. The target population was comprised of Spanish patients who were undergoing initial assessment for cognitive impairment (Mini-Mental State Examination [MMSE] score=20). Diagnostic accuracy, rate of cognitive decline, effect of drugs on cognition and dwelling status, economic burden (direct and indirect costs), and quality of life (QoL) were based on relevant clinical studies and published literature. Scenario analysis was applied to explore outcomes under different conditions, which included: (i) use of florbetapir-PET earlier in disease progression (MMSE score=22); and (ii) the addition of fluorodeoxyglucose (FDG)-PET to SCE. RESULTS: Adjunctive florbetapir-PET increased quality-adjusted life years (QALYs) by 0.008 years and increased costs by 36 compared to SCE alone (incremental cost-effectiveness ratio [ICER], 4,769). Use of florbetapir-PET was dominant in alternate scenarios. Sensitivity analyses indicated rates of institutionalization (by MMSE) and MMSE score upon initiation of acetylcholinesterase inhibitor (AChEI) treatment most influenced the primary outcome (ICER) in the base case scenario. Over 82% of probabilistic simulations were cost-effective using the Spanish threshold (30,000/QALY). DISCUSSION: The addition of florbetapir-PET to SCE is expected to improve the accuracy of AD diagnoses for patients experiencing cognitive impairment; it is cost-effective due to decreased healthcare costs and caregiver burden. Prospective studies of the clinical utility of florbetapir-PET are necessary to evaluate the long-term implications of adopting florbetapir-PET on clinical outcomes and costs in real-world settings. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: Florbetapir-PET is expected to improve decision-making regarding appropriate and sufficient care for cognitively impaired patients with suspected AD, while cost-effective. IMPLICATIONS FOR HEALTH POLICIES: Earlier and more accurate diagnosis of AD may help to improve patient's health status and reduce treatment costs by effectively allocating healthcare resources and maximizing the benefit of treatments and supportive services. IMPLICATIONS FOR FURTHER RESEARCH: Use of florbetapir-PET may help accurately identify patients with AD. The development of novel therapeutics for use with companion diagnostics may provide additional benefits by slowing or halting progressive cognitive decline with AD, increase QoL and prolong survival.

Societal cost-effectiveness analysis of the 21-gene assay in estrogen-receptor-positive, lymph-node-negative early-stage breast cancer in Japan.

BACKGROUND: Breast-cancer incidence and mortality have been increasing in Japan. Japanese-specific clinical validity and utility data for the 21-gene assay (Oncotype DX® Breast Cancer Assay; Genomic Health, Inc., Redwood City, USA) are now available. The objective of this study was to evaluate the cost-effectiveness of the 21-gene assay for the guidance of adjuvant chemotherapy decisions in estrogen-receptor-positive, lymph-node-negative, early-stage breast cancer patients, from the Japanese societal perspective. METHODS: The recurrence risk group distribution by the 21-gene assay result and the assay's influence on adjuvant chemotherapy recommendations were obtained from a study of 104 patients. A state-transition cohort (Markov) model tracked time from surgery until distant recurrence and from distant recurrence to death. Adjuvant chemotherapy benefit by 21-gene assay risk group was based on published clinical validation studies. Direct and indirect medical costs were obtained from the referral centers. Utilities associated with progression and chemotherapy-related adverse events were extracted from literature. Sensitivity analyses assessed the key drivers and robustness of the primary outcomes. RESULTS: The 21-gene assay identified 48% of patients as low-risk, 36% as intermediate-risk, and 16% as high-risk. Total acute chemotherapy-related costs decreased by ¥154,066 due to less adjuvant chemotherapy usage. In the high-risk group, adjuvant chemotherapy use increased 18%, leading to survival benefits. Chemotherapy use overall decreased by 19%. Monitoring costs increased by ¥3,744 but recurrence costs declined by ¥46,113 per patient. Use of the 21-gene assay increased quality-adjusted-life-years (QALYs) by 0.241 per patient on average; the net cost per QALY gained was ¥636,752 ($6,368). CONCLUSIONS: The 21-gene assay for women with estrogen-receptor-positive, lymph-node-negative, early-stage breast cancer is projected to be cost-effective in Japan.

Cost-effectiveness of gene-expression profiling for tumor-site origin.

OBJECTIVES: Gene-expression profiling (GEP) reliably supplements traditional clinicopathological information on the tissue of origin (TOO) in metastatic or poorly differentiated cancer. A cost-effectiveness analysis of GEP TOO testing versus usual care was conducted from a US third-party payer perspective. METHODS: Data on recommendation changes for chemotherapy, surgery, radiation therapy, blood tests, imaging investigations, and hospice care were obtained from a retrospective, observational study of patients whose physicians received GEP TOO test results. The effects of chemotherapy recommendation changes on survival were based on the results of trials cited in National Comprehensive Cancer Network and UpToDate guidelines. Drug and administration costs were based on average doses reported in National Comprehensive Cancer Network guidelines. Other unit costs came from Centers for Medicare & Medicaid Services fee schedules. Quality-of-life weights were obtained from literature. Bootstrap analysis estimated sample variability; probabilistic sensitivity analysis addressed parameter uncertainty. RESULTS: Chemotherapy regimen recommendations consistent with guidelines for final tumor-site diagnoses increased significantly from 42% to 65% (net difference 23%; P<0.001). Projected overall survival increased from 15.9 to 19.5 months (mean difference 3.6 months; two-sided 95% confidence interval [CI] 3.2-3.9). The average increase in quality-adjusted life-months was 2.7 months (95% CI 1.5-4.3), and average third-party payer costs per patient increased by $10,360 (95% CI $2,982-$19,192). The cost per quality-adjusted life-year gained was $46,858 (95% CI $13,351-$104,269). CONCLUSIONS: GEP TOO testing significantly altered clinical practice patterns and is projected to increase overall survival, quality-adjusted life-years, and costs, resulting in an expected cost per quality-adjusted life-year of less than $50,000.

Clinical validity of cytochrome P450 metabolism and serotonin gene variants in psychiatric pharmacotherapy.

Adverse events, response failures and medication non-compliance are common in patients receiving medications for the treatment of mental illnesses. A systematic literature review assessed whether pharmacokinetic (PK) or pharmacodynamic (PD) responses to 26 commonly prescribed antipsychotic and antidepressant medications, including efficacy or side effects, are associated with nucleotide polymorphisms in eight commonly studied genes in psychiatric pharmacotherapy: CYP2D6, CYP2C19, CYP2C9, CYP1A2, CYP3A4, HTR2C, HTR2A, and SLC6A4. Of the 294 publications included in this review, 168 (57%) showed significant associations between gene variants and PK or PD outcomes. Other studies that showed no association often had insufficient control for confounding variables, such as co-medication use, or analysis of medications not substrates of the target gene. The strongest gene-outcome associations were for the PK profiles of CYP2C19 and CYP2D6 (93% and 90%, respectively), for the PD associations between HTR2C and weight gain (57%), and for SLC6A4 and clinical response (54%), with stronger SLC6A4 response associations for specific drug classes (60-83%). The preponderance of evidence supports the validity of analyzing nucleotide polymorphisms in CYP and pharmacodynamic genes to predict the metabolism, safety, or therapeutic efficacy of psychotropic medications commonly used for the treatment of depression, schizophrenia, and bipolar illness.

Financial implications of choice of dialysis type of the revised Medicare payment system: an economic analysis.

BACKGROUND: In 2011, the Medicare Improvements for Patients and Providers Act replaced the case-mix-adjusted composite payment system for Medicare outpatient dialysis facilities with a bundled end-stage renal disease prospective payment system (PPS). We assessed the economic implications for modality choice of the revised Medicare payment system. STUDY DESIGN: Microeconomic analyses. SETTING & POPULATION: Patients eligible for dialysis in the United States. MODEL, PERSPECTIVE, & TIMEFRAME: The perspective of this analysis is that of a financial administrator of a representative dialysis center in the United States. Data were obtained from the Medicare Payment Advisory Commission, the US Renal Data System, the DOPPS (Dialysis Outcomes and Practice Patterns Study) Practice Monitor, the US Bureau of Labor Statistics, and Medicare fee schedules. INTERVENTIONS: Recently implemented end-stage renal disease PPS versus the prior case-mix composite payment system. OUTCOMES: Medicare payment per month, center fixed and variable costs per month, net difference in revenue and variable costs (direct contribution), and net difference in revenue and total costs (operating margin). RESULTS: The direct contribution and operating margin for in-center hemodialysis and peritoneal dialysis are expected to be positive under the new bundled PPS. For Medicare fiscal intermediaries/administrators, paid treatments for home hemodialysis vary from 3.2 to more than 4.8 per week. The direct contribution and operating margin are expected to be negative for home hemodialysis if the number of paid treatments is similar between in-center and home hemodialysis; they are almost identical when the number of paid treatments increases for home hemodialysis by approximately 1 per week. LIMITATIONS: Experience across centers and intermediaries/administrators may vary. Sensitivity analyses were conducted to assess the robustness of findings and determine which variables most influenced results. CONCLUSIONS: The new bundled PPS created a financial incentive for increased use of peritoneal dialysis. Use of home hemodialysis may be influenced by number of paid treatments per week.

A multigene prognostic assay for selection of adjuvant chemotherapy in patients with T3, stage II colon cancer: impact on quality-adjusted life expectancy and costs.

OBJECTIVES: Uncertainty exists regarding appropriate and affordable use of adjuvant chemotherapy in stage II colon cancer (T3, proficient DNA mismatch repair). This study aimed to estimate the effectiveness and costs from a US societal perspective of a multigene recurrence score (RS) assay for patients recently diagnosed with stage II colon cancer (T3, proficient DNA mismatch repair) eligible for adjuvant chemotherapy. METHODS: RS was compared with guideline-recommended clinicopathological factors (tumor stage, lymph nodes examined, tumor grade, and lymphovascular invasion) by using a state-transition (Markov) lifetime model. Data were obtained from published literature, a randomized controlled trial (QUick And Simple And Reliable) of adjuvant chemotherapy, and rates of chemotherapy use from the National Cooperative Cancer Network Colon/Rectum Cancer Outcomes study. Life-years, quality-adjusted life expectancy, and lifetime costs were examined. RESULTS: The RS is projected to reduce adjuvant chemotherapy use by 17% compared with current treatment patterns and to increase quality-adjusted life expectancy by an average of 0.035 years. Direct medical costs are expected to decrease by an average of $2971 per patient. The assay was cost saving for all subgroups of patients stratified by clinicopathologic factors. The most influential variables affecting treatment decisions were projected years of life remaining, recurrence score, and patients' disutilities associated with adjuvant chemotherapy. CONCLUSIONS: Use of the multigene RS to assess recurrence risk after surgery in stage II colon cancer (T3, proficient DNA mismatch repair) may reduce the use of adjuvant chemotherapy without decreasing quality-adjusted life expectancy and be cost saving from a societal perspective. These findings need to be validated in additional cohorts, including studies of clinical practice as assay use diffuses into nonacademic settings.

Challenges in the development and reimbursement of personalized medicine-payer and manufacturer perspectives and implications for health economics and outcomes research: a report of the ISPOR personalized medicine special interest group.

BACKGROUND: Personalized medicine technologies can improve individual health by delivering the right dose of the right drug to the right patient at the right time but create challenges in deciding which technologies offer sufficient value to justify widespread diffusion. Personalized medicine technologies, however, do not neatly fit into existing health technology assessment and reimbursement processes. OBJECTIVES: In this article, the Personalized Medicine Special Interest Group of the International Society for Pharmacoeconomics and Outcomes Research evaluated key development and reimbursement considerations from the payer and manufacturer perspectives. METHODS: Five key areas in which health economics and outcomes research best practices could be developed to improve value assessment, reimbursement, and patient access decisions for personalized medicine have been identified. RESULTS: These areas are as follows: 1 research prioritization and early value assessment, 2 best practices for clinical evidence development, 3 best practices for health economic assessment, 4 addressing health technology assessment challenges, and 5 new incentive and reimbursement approaches for personalized medicine. CONCLUSIONS: Key gaps in health economics and outcomes research best practices, decision standards, and value assessment processes are also discussed, along with next steps for evolving health economics and outcomes research practices in personalized medicine.

The cost-effectiveness of bortezomib in relapsed/refractory multiple myeloma: Swedish perspective.

OBJECTIVES: To estimate the cost-effectiveness of bortezomib (BTZ) compared with dexamethasone (DEX) and lenalidomide plus dexamethasone (LEN/DEX) for the treatment of relapsed/refractory multiple myeloma in Sweden. METHODS: We used partitioned survival analysis to assess survival data decomposed into three states: (i) alive before disease progression; (ii) alive after progression; and (iii) dead. The effects of treatment on time to progression and overall survival (OS) were obtained from published reports of the APEX, MM-009, and MM-010 randomized clinical trials. Costs included drug and administration costs, adverse events, treatment of relapses, and end-of-life costs. Utility estimates were derived from the literature. RESULTS: BTZ mean OS was 57.4 months compared with 44.6 and 54.1 months for DEX and LEN/DEX, respectively. Mean lifetime direct medical costs per patient were approximately 2010 SEK 1,904,462, 1,278,854, and 2,450,588 for BTZ, DEX, and LEN/DEX, respectively. Mean incremental cost per quality-adjusted life-year of BTZ compared to DEX was 2010 SEK 902,874 (€95,073) (95% CI: 514,791, 962,416) and was dominant with respect to LEN/DEX. CONCLUSION: BTZ and LEN/DEX are projected to prolong survival relative to DEX. From a Swedish perspective, BTZ is cost-effective compared to DEX and LEN/DEX.

Economic implications of 21-gene breast cancer risk assay from the perspective of an Israeli-managed health-care organization.

OBJECTIVE: Oncotype DX, a 21-gene assay, was clinically validated as a predictor of 10-year recurrence-free survival and treatment response in patients with early-stage estrogen-receptor-positive, lymph-node negative breast cancer (ER+ LN- ESBC). This study determined "real-life" alteration in treatment decision and economic implications of Oncotype DX use in women with ER+ LN- ESBC. METHODS: Clalit Health Services (CHS, Tel Aviv, Israel), determined the proportion of women in low, intermediate and high-risk groups in the first 368 Oncotype DX assays performed, the change of adjuvant therapy recommendation following the recurrence (RS) results from Oncotype DX use, and associated chemotherapy costs. The risk of recurrence-free survival was derived from prespecified statistical protocols of NCI-sponsored trials conducted by NSABP (B-14 and B-20). Utilities were literature based. A 3% discount rate was employed. RESULTS: Oncotype DX altered recommendations of 40% of patients, 84% of whom were changed from hormone + chemotherapy to hormonal therapy alone. Among high-risk women, 8% switched actual treatment from hormonal therapy to hormone + chemotherapy. By reducing the chemotherapy disutility, quality-adjusted life-years (QALY) increased 0.170 years. Use of Oncotype DX costs $10,770 per QALY gained. Sensitivity analyses revealed that risk reduction in the low-risk population, the cost of adverse events, and the relative risk reduction of recurrence were the most influential variables. CONCLUSION: Oncotype DX resulted in net QALY gain and increased overall costs, with an incremental cost-effectiveness ratio of $10,770. For CHS, Oncotype DX represents an effective and affordable approach to favorably affect the lives of women with ESBC.

Obstacles and proposed solutions to effective antiretroviral therapy in resource-limited settings.

More than 3 million people were receiving antiretroviral therapy (ART) at the end of 2007, but this number represents only 31% of people clinically eligible for ART in resource-limited settings. The primary objective of this study is to summarize the key obstacles that impede the goal of universal access prevention, care, and treatment. We performed a systematic literature search to review studies that reported barriers to diagnosis and access to treatment of HIV/AIDS in resource-limited countries. Persons living with HIV/ AIDS commonly face economic, sociocultural, and behavioral obstacles to access treatment and care for HIV. A variety of programs to overcome these barriers have been implemented, including efforts to destigmatize HIV/AIDS, enhance treatment literacy, provide income-generation skills, decentralize HIV services, promote gender equality, and adopt a multisectoral approach to optimize limited resources. An understanding of these obstacles and suggested methods to overcome them must be addressed by global policy makers before universal ART access can be achieved.

Multi-gene assays: effect on chemotherapy use, toxicity and cost in estrogen receptor-positive early stage breast cancer.

AIM: To assess multi-gene assay (MGA) effects on chemotherapy use, toxicities, recurrences, and costs in estrogen receptor-positive early breast cancer. METHODS: Meta-analysis performed using data from public databases. Results: Studies included 12,202 women. Relative to no testing, chemotherapy use was higher with 12-gene and 70-gene and lower with PAM50 (commercial) and 21-gene MGAs. Overall, 1643 distant recurrences occurred with no testing, declining by 231 (21-gene), 121 (70-gene), 54 (12-gene) and 94 (PAM50); only the 21-gene assay resulted in no risk of increasing the number of distant recurrences. Relative to 'no testing', total cost of care declined only with 21-gene MGA. CONCLUSION: MGAs differ in chemotherapy use and related outcomes for women with estrogen receptor-positive early breast cancer.

A Promising New Strategy to Improve Treatment Outcomes for Patients with Depression.

Each year, ineffective medical management of patients with mental illness compromises the health and well-being of individuals, and also impacts communities and our society. A variety of interrelated factors have impeded the health system's ability to treat patients with behavior health conditions adequately. A key contributing factor is a lack of objective markers to help predict patient response to specific drugs that has led to patterns of "trial and error" prescribing. For many years, clinicians have sought objective data (eg, a laboratory or imaging test) to assist them in selecting appropriate treatments for individual patients. Electroencephalogram (EEG) findings coupled with medication outcomes data may provide a solution. "Crowdsourced" physician registries that reference clinical outcomes to individual patient physiology have been used successfully for cancers. These techniques are now being explored in the context of behavioral health care. The Psychiatric EEG Evaluation Registry (PEER) is one such approach. PEER is a clinical phenotypic database comprising more than 11,000 baseline EEGs and more than 39,000 outcomes of medication treatment for a variety of mental health diagnoses. Collective findings from 45 studies (3130 patients) provide compelling evidence for PEER as a relatively simple, inexpensive predictor of likely patient response to specific antidepressants and likely treatment-related side effects (including suicidal ideation).
