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.

Dr. Sadeghi: Several years ago analyses of outcomes for radical prostatectomy highlighted the significant impact of surgical experience on the oncological outcome for the patients. In this case experience was measured by the number of radical prostatectomies performed by the surgeon, and oncological outcome was measured by treatment failure rates (rising PSA). Despite this data, the move for redirecting patients to “high volume centers” where more experienced surgeons perform the operation has been sluggish. There was insufficient data on what is involved in referring patients to high volume centers and whether or not such action is cost effective.
In a previous study we demonstrated that for every referral to a high volume center, there would be an average of $1,800 over a follow-up period of 20 years in societal cost savings. The main source of these savings is fewer treatment failures.
The next question was who is a good candidate for referral and whether these savings can offset the referral costs.

Dr. Moise: Our research aimed to compare the number of lives saved and changes in medical costs expected if intensive blood pressure goals of less than 120 mmHg were implemented in high cardiovascular disease risk patients.
In 2014, the 8th Joint National Committee (JNC8) on Detection, Evaluation, and Treatment of High Blood Pressure issued new guidelines recommending that physicians aim for a systolic blood pressure (SBP) of 140 mmHg in adults with diabetes and/or chronic kidney disease and 150 mmHg in healthy adults over age 60. The new guidelines represented a major departure from previous JNC7 guidelines recommending SBPs of 130 mmHg and 140, mmHg for these groups, respectively. Under the 2014 guidelines, over 5 million fewer individuals annually would receive drug treatment to lower their blood pressure, compared with the prior 2003 guidelines.
Recently, the Systolic Blood Pressure Intervention Trial (SPRINT) found that having a more intensive systolic blood pressure (SBP) goal of 120 mmHg in patients at high risk for cardiovascular disease reduced both cardiovascular events and mortality by about one quarter, compared with the current goal of 140 mmHg.
These recent studies and guidelines have created uncertainty about the safest, most effective and high-value blood pressure goals for U.S. adults with hypertension, but no prior study has compared the cost-effectiveness of adding more intensive blood pressure goals in high cardiovascular disease risk groups to standard national primary prevention hypertension guidelines like JNC8 and JNC7.
Our team at Columbia University Medical Center conducted a computer simulation study to determine the value of adding the lower, life-saving systolic blood pressure goal identified in SPRINT to the JNC7 and JNC8 guidelines for high-risk patients between the ages of 35 and 74 years. (High risk was defined as existing cardiovascular disease, chronic kidney disease, or a 10-year cardiovascular disease risk greater than 15 percent in patients older than 50 years and with a pre-treatment SBP greater than 130 mmHg)

Dr. Lakdawalla: New treatments for hepatitis-C are highly effective but also involve high upfront costs. Because they effectively cure the disease, all the costs of treatments are paid over a short period of time – about three months – but the benefits accrue for the rest of a patient’s life. This creates problems for the private health insurance system, where patients switch insurers. The insurer that pays the bill for the treatment might not be around to enjoy the benefits of averting liver damage, liver transplants, and other costly complications associated with hepatitis-C.

Dr. Sommers: We conducted this study in an effort to see how Native Americans have fared under the Affordable Care Act. In addition to the law's expansion of coverage via Medicaid and tax credits for the health insurance marketplaces, the law also provided support for Native Americans’ health care specifically through continued funding of the Indian Health Service (IHS). We sought to see how both health insurance coverage patterns and IHS use changed in the first year of the law's implementation.

MedicalResearch.com: What is the purpose for this study?
Dr. Yeh: A number of factors influence physicians’ prescribing behavior, including physician’s knowledge and understanding of the drugs. Pharmaceutical detailing and financial incentives may affect such behavior. My interest in evidence-based medicine and how medical knowledge is translated into practice lead me to think about how physicians’ financial relationships with the pharmaceutical industry may affect prescribing patterns.
In our study, we linked the Massachusetts physicians open payment database with the Medicare drug prescription claims database to determine if financial relationships with the industry are associated with increased brand-name statin drug prescribing. The open payment database reports payments that physicians receive from pharmaceutical and medical device industries. The open payment database when linked to the drug prescription claims database allowed us to answer this question.
We looked at year 2011, when two of the most commonly prescribed brand-name statin drugs (Lipitor and Crestor) were not yet available in generic formulation.
The outcome measured was what percentage of all statin prescription claims (both generic and brand-name) were brand-names.

MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Sills: Often regarded as a miracle procedure by many infertile couples, in vitro fertilization (IVF) can be financially difficult for those without insurance coverage for the treatment. This prohibitive cost leads many would-be parents who pursue IVF to transfer multiple embryos at once, to increase their chances of getting a baby and minimize the need for additional attempts.
This new study now reports that the economic impact of IVF deserves a closer look. As corresponding author E. Scott Sills, MD PhD noted, rates of cesarean-section deliveries, premature births, and low birth weight of babies are all greater with two or more embryos transferred to the mother at once, compared to a lower risk, single-embryo pregnancy.
The data derived from a comprehensive analysis of all IVF cases in Vermont (UVM) and was recently published in the journal Applied Health Economics & Health Policy. It is believed to be the first effort to calculate the difference in infant hospital costs based on the number of embryos transferred. Sills and his team had access to UVM Medical Center records of patients who conceived through IVF and delivered at least 20 weeks into their pregnancies between 2007 and 2011.

MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Dusetzina: Drug prices are of significant policy interest, particularly the prices for so-called “specialty” medications which are used to treat rare and/or complex conditions like cancer. In this study I estimated monthly price for orally-administered cancer treatments that were approved between 2000 and 2014. First I looked at the price of the drug during the year of initial FDA approval and then I looked at annual changes in the price after the year of approval. The main findings are that, even after inflation adjustment, the monthly price paid for orally-administered cancer treatments is increasing rapidly both at the time of approval and in subsequent years.
As an example, if you compare average monthly prices during the first year post-approval for treatments approved between 2000-2010 to those approved after 2010 there was a major increase in launch prices from $5,529 per month to $9,013 per month. Year-to-year changes in price after launch varied a lot by drug ranging from decreases in price of -2.7% per year to increases of 11.4% per year. However, nearly all of the products studied increased in price over time.
