Author Interviews, Compliance, Cost of Health Care / 29.08.2016

MedicalResearch.com Interview with: Elizabeth Geneva Wood, MHPA Department of Health Policy and Administration College of Nursing Washington State University Spokane MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many people don’t fill prescriptions because they can’t afford them, which is risky for their health. The problem of cost-related nonadherence to prescriptions (CRN) was increasing in prevalence over time until several major policy changes in the 2000s that were intended to help prescription affordability and/or access to health insurance. We observed that each of these major policy changes corresponded with a decrease in CRN among the policy’s target population. For seniors, CRN dropped in 2006, when Medicare Part D came into effect. For younger adults (19-25), CRN dropped in 2010, when the Affordable Care Act began allowing them to stay on their parents’ insurance. Cost-related nonadherence rates also dropped for all non-elderly adults (including the younger ones) in 2014 and 2015, when the Medicaid expansion and the introduction of the health insurance marketplaces offered coverage to many previously-uninsured adults.

MedicalResearch.com Interview with: Rachel Patzer, PhD, MPH Director of Health Services Research, Emory Transplant Center Assistant Professor Emory University School of Medicine Department of Surgery Division of Transplantation MedicalResearch.com: What is the background for this study? Response: Patients with End Stage Renal Disease (ESRD) make up less than 1% of all Medicare patients, but account for more than 7% of all Medicare expenses. Patients with ESRD have the highest risk of hospitalization of any patient with a chronic disease, and while hospital admissions have decreased over the last several years, emergency department utilization for this patient population has increased by 3% in the last 3 years. The purpose of the study we conducted was to describe the clinical and demographic characteristics associated with emergency department utilization. (more…)
Author Interviews, Cost of Health Care, Heart Disease / 19.08.2016

MedicalResearch.com Interview with: Leo F. Buckley, PharmD Virginia Commonwealth University Richmond, Virginia MedicalResearch.com: What is the background for this study? Response: As the prevalence and costs of heart failure are expected to increase through the year 2030, significant efforts have been devoted towards devising alternatives to inpatient hospitalization for the management of heart failure decompensations. Since loop diuretics are the mainstay of treatment during the majority of hospitalizations, administration of high doses of loop diuretics in the outpatient setting has increased in popularity. We intended to answer two questions with his study: first, can a patient-specific dosing protocol based on a patient’s usual diuretic dose achieve safe decongestion? and second, does this strategy alter the usual course of heart failure decompensation, which oftentimes culminates in inpatient hospitalization?

MedicalResearch.com Interview with: Monica Morrow, MD, FACS Chief, Breast Service Department of Surgery Anne Burnett Windfohr Chair of Clinical Oncology Memorial Sloan-Kettering Cancer Center MedicalResearch.com: What is the background for this study? Response: DCIS, ductal carcinoma in situ, intraductal cancer or Stage 0 cancer refers to what some people call the earliest form of cancer we can find and others term “precancerous”. This difference in terms is due to the fact that DCIS lacks the ability to spread to other parts of the body, a fundamental characteristic of cancer. The goal of treatment in DCIS is to prevent progression to invasive cancer which has the ability to spread. DCIS accounted for only 2-3 % of breast cancers seen in the pre-screening mammography era, but it comprises 25-30% of the malignancies detected in screening mammography programs. For this reason it is uncommon in women under age 40, and more commonly seen in women over 50 years of age. Approximately 70% of the women in the US diagnosed with DCIS are treated with lumpectomy (removal of the DCIS and a margin of surrounding normal breast tissue), and additional surgeries to obtain clear, or more widely clear, margins are done in approximately 30% of women. For this reason, the Society of Surgical Oncology, the American Society for Therapeutic Radiation Oncology, and the American Society of Clinical Oncology undertook the development of an evidence based guideline to determine the optimal clear margin for women with DCIS treated with lumpectomy and whole breast radiotherapy.

MedicalResearch.com Interview with: Leo F. Buckley, PharmD Virginia Commonwealth University Richmond, Virginia MedicalResearch.com: What is the background for this study? Response: Heart failure hospitalizations have become a significant burden for both patients and the healthcare systems. Significant efforts have been devoted to identifying alternative treatment pathways for acute decompensated heart failure that do not require hospitalization. Our group previously reported our initial experience with ambulatory intravenous diuretic therapy administered serially over several days to weeks in place of inpatient hospitalization. We found that the rate of hospitalization was significantly reduced compared to expected and that the high dose furosemide protocol utilized was safe and well tolerated by patients. (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, Education, Heart Disease, JAMA / 16.08.2016

MedicalResearch.com Interview with: Rory Brett Weiner, MD Assistant Professor of Medicine Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: The increased use of noninvasive cardiac imaging and Medicare spending in the late 1990s and early 2000s has led to several measures to help optimize the use of cardiac imaging. One such effort has been the Appropriate Use Criteria (AUC) put forth by the American College of Cardiology Foundation. The AUC for echocardiography have been useful to characterize practice patterns and more recently been used as a tool to try to improve ordering of echocardiograms. Our research group previously conducted a randomized study of physicians-in-training (cardiovascular medicine fellows) and showed that an AUC based educational and feedback intervention reduced the rate of rarely appropriate transthoracic echocardiograms (TTEs). The current study represents the first randomized controlled trial of an AUC education and feedback intervention attending level cardiologists. In this study, the intervention group (which in addition to education received monthly feedback emails regarding their individual TTE ordering) ordered fewer rarely appropriate TTEs than the control group. The most common reasons for rarely appropriate TTEs in this study were ‘surveillance’ echocardiograms, referring to those in patients with known cardiac disease but no change in their clinical status.

Author Interviews, Brain Cancer - Brain Tumors, Cancer, Cost of Health Care / 12.08.2016

MedicalResearch.com Interview with: Wuyang Yang, M.D., M.S. Research Fellow Department of Neurosurgery Johns Hopkins Hospital Baltimore, MD 21287 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The treatment for glioblastoma (GBM) patients involves a combined approach of surgery, radiation therapy and chemotherapy. Despite advancement in the therapeutic approaches for GBM, differing socioeconomic status result in disparities in health-care access, and may superimpose a significant impact on survival of glioblastoma patients. Insurance status is an indirect indicator of overall socioeconomic status of a patient, and has been shown to correlate with survival of patients with malignant tumor in other parts of the body. We conducted the first study to determine a relationship between different types of insurance and survival of GBM patients. In our study of 13,665 cases of GBM patients, we found that non-Medicaid insured patients have a significant survival benefit over uninsured and even Medicaid insured patients. This is the first time a study describes this relationship in glioblastoma patients, and also the first to compare and quantify the likelihood of poor prognosis between different insurance categories. A difference in insurance coverage was also uncovered, and patients with insurance were more likely to be older, female, white, and married. In addition, we found that younger, female, married patients with smaller tumor size survive longer than other patients, which confirmed findings in existing literature. (more…)
Author Interviews, Breast Cancer, Cost of Health Care, Johns Hopkins / 11.08.2016

MedicalResearch.com Interview with: Pedram Argani, M.D. Professor of Pathology and Principal consultant of the Breast Pathology Service Johns Hopkins Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Most pathology laboratories, at the request if clinicians, automatically (reflexively) test needle core biopsies containing ductal carcinoma in situ (DCIS) for estrogen receptor (ER) and progesterone receptor (PR). The logic for testing DCIS for these hormone receptors is that, for patients who have pure DCIS that is ER positive after surgical excision, treatment with estrogen blockers like Tamoxifen can decrease the recurrence of DCIS by a small amount, though overall survival (which is excellent) is not impacted. However, there are several factors which suggest that this reflex testing unnecessarily increases costs. • First, the ER/PR results on core needle biopsy do not impact the next step in therapy; namely, surgical excision. • Second, a subset of excisions performed for DCIS diagnosed on core needle biopsy will harbor invasive breast carcinoma, which would than need to be retested for ER/PR. • Third, because ER and PR labeling is often variable in DCIS, negative results for ER/PR in a small core biopsy specimen should logically be repeated in a surgical excision specimen with larger amounts of DICS to be sure that the result is truly negative. • Fourth, many patients with pure DCIS which is ER/PR positive after surgical excision will decline hormone therapy, so any ER/PR testing of their DCIS is unnecessary. • Fifth, PR status in DCIS has no independent value. We reviewed the Johns Hopkins experience with reflex ER/PR testing of DCIS on core needle biopsies over 2 years. We found that reflex core needle biopsy specimen testing unnecessarily increased costs by approximately $140.00 per patient. We found that ER/PR testing in the excision impacted management in only approximately one third of cases, creating an unnecessary increased cost of approximately $440.00 per patient. Extrapolating the increased cost of reflex ER/PR testing of DCIS to the 60,000 new cases of DCIS in the United States each year, reflex core needle biopsy ER/PR testing unnecessarily increased costs by approximately 35 million dollars.

Author Interviews, Cost of Health Care, Emergency Care / 09.08.2016

MedicalResearch.com Interview with: Jessica Moe MD, MA, PGY5 FRCPC Emergency Medicine, University of Alberta MSc (Candidate) Clinical Epidemiology MedicalResearch.com: What is the background for this study? What are the main findings? Response: Frequent visitors are common in many urban emergency departments (ED). They represent high resource-utilizing patients; additionally, existing literature demonstrates that they experience higher mortality and adverse health outcomes than non-frequent ED users. Interventions targeting frequent ED users therefore may potentially prevent adverse outcomes in this high risk patient group. The purpose of this study was to provide an up-to-date review of the existing literature on the effectiveness of interventions for adult frequent ED users. This systematic review summarizes evidence from 31 interventional studies. The majority evaluated case management and care plans; a smaller number of studies examined diversion strategies, printout case notes, and social work visits. Overall, the studies were considered to have moderate to high risk of bias; however, 84% of before-after studies found that ED visits significantly decreased after the intervention. Additionally, studies examining interventions for homelessness consistently found that interventions improved stable housing. Overall, effects on hospital admissions and outpatient visits were unclear. In summary, the available evidence is encouraging and suggests interventions targeted towards frequent ED users may be effective in decreasing ED visit frequency and improving housing stability.

CareSkore MedicalResearch.com Interview with: CareSkore co-founders: Dr. Puneet Dhillon Grewal MD CareSkore co-founder and Chief Medical Officer Dr. Grewal is an Internal Medicine physician and Cardiologist. She had completed her residency from Rosalind Franklin University of Medical Science, and is currently a Cardiology Fellow at the same institution and Jaspinder Grewal, MBA CareSkore co-founder and Chief Executive Officer, a graduate from the University of Chicago Booth School of Business and a computer engineer. He has 13 years of experience working with large health systems , managing technology and operations. MedicalResearch.com: What is the background for the CareSkore company? What is its mission and objectives? Response: The Affordable Care Act, through penalties and bundled payments, requires hospitals and providers to be accountable for the quality of care they provide. For example, if a patient is readmitted to the hospital within 30-days after discharge, hospital reimbursement is reduced, and in many cases not paid at all. In order to improve the quality of care, hospitals need to understand the clinical risk of patients, so that they can focus efforts on the patient most likely to face adverse events. The three biggest areas of improvement are readmissions, over utilization of services, and hospital acquired conditions (such as pneumonia and surgical site infections). (more…)

MedicalResearch.com Interview with: Benjamin D. Sommers, M.D., Ph.D Assistant Professor of Health Policy & Economics Department of Health Policy & Management Harvard T.H. Chan School of Public Health Assistant Professor of Medicine Division of General Medicine & Primary Care Brigham & Women’s Hospital / Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: More than half of states have expanded Medicaid under the Affordable Care Act, and several states have taken alternative approaches, such as using federal Medicaid funds to purchase private insurance for low-income adults. Our study looks at the effects of these two different approaches - vs. not expanding at all - in three southern states (Kentucky Arkansas, and Texas). What we find is that expanding coverage, whether by Medicaid (Kentucky) or private insurance (Arkansas), leads to significant improvements in access to care, preventive care, quality of care, and self-reported health for low-income adults compared to not expanding (Texas). The benefits of the coverage expansion also took a while to become evident - the first year of expansion (2014) showed some of these changes, but they become much more apparent in the second year (2015).

Author Interviews, Cost of Health Care, Critical Care - Intensive Care - ICUs, JAMA / 08.08.2016

MedicalResearch.com Interview with: Dong W. Chang, MD, MS Dong W. Chang, MD, is a lead researcher at LA BioMed, one of the nation’s leading independent nonprofit research institutes. His research interests include improving the delivery of care to patients with a focus on identifying new healthcare models for reducing hospital re-admission. He also is the director of Medical-Respiratory ICU at Harbor-UCLA Medical Center in Torrance MedicalResearch.com: What is the background for this study? What are the main findings? Response: With the use of intensive care units (ICUs) on the rise in many hospitals, researchers at LA BioMed and UCLA examined ICU usage. They found patients who were admitted to these units underwent more costly and invasive procedures but didn’t have better mortality rates than hospitalized patients with the same medical conditions who weren’t admitted to the ICU. The study, published in JAMA Internal Medicine, examined records from 156,842 hospitalizations at 94 acute care hospitals for four medical conditions where ICU care is frequently provided but may not be medically necessary:diabetic ketoacidosis, pulmonary embolism, upper gastrointestinal hemorrhage and congestive heart failure. The study found the hospitals that utilize ICUs more frequently were more likely to perform invasive procedures and incur higher costs. But the study found these hospitals had no improvement in mortality among patients in the ICU when compared with other hospitalized patients with these four conditions. Smaller hospitals and teaching hospitals used ICUs at higher rates for patients with the four conditions studied that did larger hospitals. The difference in the average costs ranged from $647 more for upper gastrointestinal hemorrhage care in the ICU to $3,412 more to care for a patient with congestive heart failure in the ICU when compared with hospital care for the same conditions outside the ICU.

MedicalResearch.com Interview with: Sarah C. Markt, ScD, MPH Research Associate Harvard T.H. Chan School of Public Health | Department of Epidemiology Boston, MA 02115 MedicalResearch.com: What is the background for this study? Response: Age is associated with insurance status, with the greatest proportion of uninsured between the ages of 20 to 34 years. For testicular cancer this is important because the median age of diagnosis is 33 years and the majority of the cases are diagnosed between then ages of 20 and 44 years. Previous studies have shown that people with cancer who are uninsured are more likely to present with worse disease, less likely to receive treatment, and are more likely to die of their disease, compared with those who have private insurance. Furthermore, the associations between Medicaid coverage and cancer outcomes have been conflicting. (more…)

MedicalResearch.com Interview with: Richard Hoehn, MD Resident in General Surgery College of Medicine University of Cincinnati MedicalResearch.com: What is the background for this study? What are the main findings? Response: A recent study from our research group (Hoehn et al, JAMA Surgery, 2015) found that safety-net hospitals perform complex surgery with higher costs compared to other hospitals, and that these higher costs are potentially due to intrinsic differences in hospital performance. In this analysis, we decided to simulate different policy initiatives that attempt to reduce costs at safety-net hospitals. Using a decision analytic model, we analyzed pancreaticoduodenectomy performed at academic hospitals in the US and tried to reduce costs at safety-net hospitals by either 1) reducing their mortality, 2) reducing their patients’ comorbidities and complications, or 3) sending their patients to non-safety-net hospitals for their surgery. While reducing mortality had a negligible impact on cost and reducing comorbidities/complications had a noticeable impact on cost, far and away the most successful way to reduce costs at safety-net hospitals, based on our model, was to send patients away from safety-net hospitals for their pancreaticoduodenectomy.

MedicalResearch.com Interview with: James C. Robinson PhD Leonard D. Schaeffer Professor of Health Economics Director, Berkeley Center for Health Technology Division Head, Health Policy and Management University of California School of Public Health Berkeley, CA MedicalResearch.com: What is the background for this study? Response: To moderate the increase in insurance premiums, employers are increasing consumer cost sharing requirements. Under reference pricing, the employer establishes a limit to what it will contribute towards each service or product, typically set at the 60th percentile or other midpoint in the distribution of prices in the market. If the patient selects a facility charging less than or equal to this contribution, he/she receives full coverage, but if a more expensive facility is chosen, the patient must pay the full difference.

Author Interviews, Beth Israel Deaconess, Biomarkers, Cost of Health Care, Medical Imaging, Ovarian Cancer / 22.07.2016

MedicalResearch.com Interview with: Katharine Mckinley Esselen, M.D. Instructor in Obstetrics, Gynecology and Reproductive Biology Beth Israel Deaconess Medical Center Brigham and Womens Hospital MedicalResearch.com: What is the background for this study? Response: There is no consensus on how to follow a patient in remission from ovarian cancer in order to detect recurrent disease. However, a 2009 randomized clinical trial demonstrated that using CA-125 blood tests for routine surveillance in ovarian cancer increases the use of chemotherapy and decreases patient’s quality of life without improving survival compared with clinical observation. Published guidelines categorize CA-125 tests as optional and discourage the use of radiographic imaging for routine surveillance. Thus, this study aims to examine the use of CA-125 tests and CT scans at 6 Cancer Centers and to estimate the economic impact of this surveillance testing for ovarian cancer. (more…)

Medicalresearch.com Interview with: Alex Mainor, JD, MPH Research Project Coordinator The Dartmouth Institute for Health Policy and Clinical Practice Lebanon, NH 03756 Carrie H. Colla, Alexander J. Mainor, Courtney Hargreaves, Thomas Sequist, Nancy Morden MedicalResearch.com: What is the background for this study? What are the main findings? Response: Waste in the healthcare system is an important concern to healthcare providers, patients, policymakers, and taxpayers, and is estimated to account for 30% of all healthcare costs. Low-value care can expose patients to unnecessary costs for little or no medical benefit, or to potential harm from unnecessary tests and procedures. In recent years, the concept of low-value care has gained wider acknowledgement and acceptance as a pressing concern for the healthcare system, and many interventions have been studied to reduce the use of this wasteful care. However, the landscape of these interventions has not been studied in a systematic and comprehensive way. In this review, we found that interventions to reduce the use of wasteful medical care are often studied and published selectively. Findings suggest that interventions using clinical decision support, clinician education, patient education, and interventions combining elements from each have strong potential to reduce low-value care.

MedicalResearch.com Interview with: Thomas P. Meehan, MD, MPH Associate Medical Director Harvard Pilgrim Health Care Qualidigm, Wethersfield Quinnipiac University, North Haven CT MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is a national effort to decrease preventable hospital readmissions in order to improve both the quality and cost of healthcare. Part of this national effort includes local quality improvement projects which are organized and conducted by a variety of organizations working by themselves or with others. We describe one statewide quality improvement project which was led by a Medicare-funded Quality Improvement Organization and conducted with a hospital association and many other collaborators. We document our activities and a relative decrease in the statewide 30-day aggregate readmission rate among fee-for service Medicare beneficiaries of 20.3% over four and a half years. While we are extremely proud of our work and this outcome, we recognize that there are many factors that impacted the outcome and that we can’t claim sole credit. (more…)

MedicalResearch.com Interview with: Leigh Purvis, MPA Director of Health Services Research AARP Public Policy Institute Editors’ note: In conjunction with the AARP’s new investigative piece, 'Supplement Pills That Promise Too Much', Leigh Purvis, Director of the AARP Health Services Research program discussed the issue of the proliferation of supplements, often with labels that make extraordinary health benefit claims. MedicalResearch.com: How many Americans use nutritional supplements? How big is the business of supplements? Response: Supplements are very popular in the United States. This is particularly true for older adults. A recent study found that the proportion of older adults using supplements increased from 52 percent in 2005 to 64 percent in 2011, and the share using multiple supplements grew by nearly 50 percent. According to the National Institutes of Health, American spent an estimated $36.7 billion on dietary supplements in 2014. (more…)

MedicalResearch.com Interview with: Laura B. Vater, MPH MD Candidate 2017 Indiana University School of Medicine MedicalResearch.com: What is the background for this study? Response: In the United States, cancer center advertisements are common. Previous research has shown that these ads use emotion-based techniques to influence viewers and omit information about benefits, risks, and costs of cancer treatment. There is a concern that cancer center advertising may increase demand for unnecessary tests and treatments, increase healthcare costs, and provide unrealistic expectations about the benefits of cancer treatment. In this study, we examined cancer center advertising spending from 2005 to 2014, with particular attention to trends within media (television networks, magazines, newspapers, radio stations, billboards, and the Internet) and by target audience (national versus local).

MedicalResearch.com Interview with: Lisa Soleymani Lehmann, MD, PhD Associate Professor of Medicine and Medical Ethics Director, Center for Bioethics Brigham and Women's Hospital Harvard Medical School Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: The background for this study is the Choosing Wisely Campaign from the American Board of Internal Medicine (ABIM). This campaign has asked specialty boards to come up with lists of interventions (e.g., imaging, medications, tests) that patients and doctors should question. When it initially came out, we thought it was a great idea, but wondered if patients and doctors would agree that some of the interventions are low value. It’s hard to cut back on things that patients feel are valuable to their care, especially as patient ratings of their doctor’s care become part of hospital ratings and physician reimbursement.

AHRQ, Author Interviews, Cost of Health Care / 07.07.2016

MedicalResearch.com Interview with: Jessica Vistnes, Ph.D. Senior Economist, Center for Financing, Access and Cost Trends Agency for Healthcare Research and Quality MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Medical Expenditure Panel Survey – Household Component (MEPS-HC), sponsored by the Agency for Healthcare Research and Quality (AHRQ), is one of the few sources of nationally representative data that can assess changes in the percentage of Americans gaining and losing health insurance coverage between 2013 and 2014, the first year that many provisions of the Affordable Care Act (ACA) were implemented. The MEPS-HC is also one of the few data sources that can be used to assess changes in the rates at which Americans are uninsured for a full calendar year. Three new AHRQ studies use data from the MEPS-HC and show large declines from 2013 to 2014 in the percentage of non-elderly adults who were uninsured throughout the calendar year. They also show large increases in the likelihood of gaining health care coverage from 2013-2014 compared to 2012-2013 across demographic groups defined by age, race/ethnicity and education. (more…)
Author Interviews, Colon Cancer, Cost of Health Care, Gastrointestinal Disease, Vanderbilt / 06.07.2016

MedicalResearch.com Interview with: Erica R. H. Sutton, MD Assistant Professor Department of Surgery, General Vanderbilt MedicalResearch.com: What is the background for this study? What are the main findings? Response: Colorectal cancer is one of the most preventable diseases that we face; however, despite the great strides that we have made in the realm of early detection, many people still do not undergo screenings. We sought to increase the availability of screenings to those in our community who are at high risk for colorectal cancer and uninsured by providing free colonoscopies to them and to examine the cost-effectiveness of this intervention. Over a 12-month period, 682 uninsured people underwent screening colonoscopies, and 9 cancers were detected. Compared to the Surveillance, Epidemiology, and End Results (SEER) registry, our patient population included more early-stage cancers, and our program was found to be cost-neutral. (more…)
Alzheimer's - Dementia, Author Interviews, Cost of Health Care, Geriatrics / 22.06.2016

MedicalResearch.com Interview with: Pei-Jung Lin, Ph.D. Assistant Professor Center for the Evaluation of Value and Risk in Health Institute for Clinical Research and Health Policy Studies Tufts Medical Center Boston, MA 02111 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Alzheimer’s disease (AD) is a slow, progressive disease. Many people with AD may live for years with the disease left unrecognized or untreated, in part because the early symptoms are mild and often mistaken as part of normal aging. In this study, we found that Alzheimer’s patients may use more health care services and incur higher costs than those without dementia even before they receive a formal diagnosis. For example, total Medicare expenditures were 42% higher among Alzheimer’s patients than matched controls during the year prior to diagnosis ($15,091 vs. $10,622), and 192% higher in the first year immediately following diagnosis ($27,126 vs. $9,274). We also found similar trends among Medicare patients with mild cognitive impairment (MCI)— a prodromal stage of AD and associated with higher dementia risk. Our study suggests that an Alzheimer’s disease or MCI diagnosis appears to be prompted by other health problems such as cardiovascular and cerebrovascular diseases, pneumonia, renal failure, urinary tract infections, and blood and respiratory infections. This finding likely reflects a failure of ambulatory care related to the impact of cognitive impairment on other chronic conditions. (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, Heart Disease, JAMA, Pharmacology / 22.06.2016

MedicalResearch.com Interview with: Thomas Andrew Gaziano, MD, MSc Department of Cardiology Assistant Professor Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Heart failure (HF) is the leading cause of admissions to hospitals in the United States and the associated costs run between $24-47 billion annually. Targeting neurohormonal pathways that aggravate the disease has the potential to reduce admissions. Enalapril, an angiotensin converting enzyme-inhibitor (ACEI), is more commonly prescribed to treat HF than Sacubitril/Valsartan, an angiotensin-receptor/neprilysin inhibitor (ARNI). The latter was shown to reduce cardiovascular death and hospitalizations due to heart failure in a multi-country, randomized clinical (PARADIGM-HF), compared to Enalapril. In order to assess the cost-effectiveness of Sacubitril/Valsartan, compared to Enalapril, in the United States, we created a model population with population characteristics equivalent to the population in the PARADIGM-HF trial. Using a 2-state Markov model we simulated HF death and hospitalizations for patients with a left ventricular ejection fraction (LVEF) of 40% or less. (more…)
Annals Internal Medicine, Author Interviews, Cost of Health Care, Hepatitis - Liver Disease / 20.06.2016

MedicalResearch.com Interview with: J. Morgan Freiman, MD Infectious disease research fellow Boston Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Freiman:  There are 130-150 million persons infected with chronic HCV with 75% of all cases occurring in low- and middle- income countries (LMICs). Diagnosis is a 2-step process that starts with screening for exposure with an assay that detects antibodies to HCV (anti-HCV), followed by nucleic acid testing (NAT) for persons with reactive anti-HCV to measure HCV ribonucleic acid (RNA) and confirm active viremia. In LMICs diagnostic capacity is low, and fewer than 1% of patients are aware of their infection. Additionally, a significant proportion of patients who test positive for anti-HCV are lost to follow-up before nucleic acid testing. The 2-step diagnostic process is thus a major bottleneck to the HCV cascade of care. Testing for hepatitis C virus core antigen (HCVcAg) is a potential replacement for NAT. Our systematic review evaluated the accuracy of diagnosis of active HCV infection among adults and children for 5 commercially available HCVcAg tests compared with NAT. We found that HCVcAg assays with signal amplification have high sensitivity, high specificity, and have the potential to replace NAT in settings with high HCV prevalence. (more…)
AHRQ, Author Interviews, Cost of Health Care / 16.06.2016

MedicalResearch.com Interview with: Celeste M. Torio, Ph.D., M.P.H Scientific Review Officer AHRQ MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Torio: Hospital care expenditures constitute the largest single component of health care spending. These expenses are of significant concern to policymakers because of their impact on governments, consumers and insurers. MedicalResearch.com: What are the main findings? • Aggregate hospital costs for 35.6 million hospital stays totaled $381.4 billion in 2013. • Septicemia, osteoarthritis, newborn infants, complication of device, and acute myocardial infarction are the five most expensive conditions, and account for 1/5 of the total aggregate costs for hospitalizations. • Sixty-three percent of aggregate hospital costs were covered by Medicare and Medicaid, while 28 percent were covered by private insurance and 5 percent were covered by the uninsured.

Author Interviews, Cost of Health Care, JAMA, Macular Degeneration, Ophthalmology / 09.06.2016

MedicalResearch.com Interview with: Adam Glassman, M.S. Director, DRCRnet Coordinating Center Jaeb Center for Health Research Tampa, FL 33647 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Diabetic macular edema (DME) is the most common cause of vision loss in patients with diabetes, impairing the vision of approximately 750,000 people in the United States. The most common treatment involves the injection into the eye of one of 3 drugs that inhibit vascular endothelial growth factor (VEGF). The Diabetic Retinopathy Clinical Research Network, funded by the National Institutes of Health, conducted a randomized clinical trial on the comparative effectiveness of the 3 anti-VEGF drugs EYLEA®, Avastin®, or Lucentis® for eyes with decreased vision from diabetic macular edema. There are substantial cost differences between the three drugs. In the United States, EYLEA® costs approximately $1850, repackaged (compounded) Avastin® $60, and Lucentis® $1170 per injection. In eyes with relatively good starting vision, there were no differences in vision outcomes; all three groups, on average, had improved vision. In eyes with starting vision of 20/50 or worse, EYLEA® had better vision outcomes at 1 year than either Avastin® or Lucentis®, and better vision outcomes at 2 years than Avastin®. However, given that, on average, eyes will receive 9 to 10 injections within the first year of treatment and 5 injections in the second year, neither EYLEA® nor Lucentis® would be considered cost effective by standard benchmarks compared with Avastin® unless their prices decrease substantially.

MedicalResearch.com Interview with: Neil T. Mason, MBA Personalized Medicine Strategist Personalized Cancer Medicine Division of Population Science Moffitt Cancer Center MedicalResearch: What is the background for this study? What are the main findings? Response: Immune checkpoint inhibitors targeting PD-1 (nivolumab and pembrolizumab) and CTLA-4 (ipilimumab) have revolutionized the treatment of metastatic disease in melanoma and non-small cell lung cancer with additional indications showing positive results. These drugs have elicited profound and durable responses in a significant number of patients, but have been criticized for their high cost. Though the price of the drugs themselves can reach over $100,000 per year, they can also cause severe, life threatening toxicities that are difficult and expensive manage. This model utilizes patient data from a large, NCI-designated cancer center to estimate the average cost of treatment with immune checkpoint inhibitors based on average duration of treatment and reported incidence of major toxicities. Based on the model, PD-1 inhibitor therapies are less costly than ipilimumab due to the significantly higher cost per dose of ipilimumab and average treatment duration of less than a year for PD-1 inhibitors. Managing drug-related toxicities were estimated to contribute between $8,200 and $9,600 to the cost of therapy with nivolumab adding the most cost. (more…)
