Author Interviews, Mental Health Research, University of Michigan / 27.10.2024

MedicalResearch.com Interview with: Daniel J. Kruger, PhD University of Michigan MedicalResearch.com: What is the background for this study? Response: A team of researchers from the University of Michigan and University at Buffalo teamed up with psychedelic advocates and therapists to document some of the challenges with psychedelics. They surveyed over a thousand psychedelic users about their adverse experiences and the experiences they have heard from others. Most reported being frightened, sadness, loneliness, and feeling their body tremble or shake at times. Some people experienced panic, paranoia, felt that they are dead, or that the state they were in would last forever. One in ten participants had adverse physical reactions.  For most people having these experiences, they are rare or happen sometimes, but they are still significant. Most of the people that experienced a severe adverse event did not have guidance from someone who was knowledgeable about psychedelics. A small portion of participants knew about an incident of inappropriate sexual contact by a psychedelic sitter, guide, or practitioner, the perpetrators were mostly underground guides and friends or acquaintances.

Author Interviews, Respiratory, Social Issues, University of Michigan / 31.01.2024

MedicalResearch.com Interview with: Wilson N. Merrell Ph.D. Student Department of Psychology University of MichiganWilson N. Merrell Ph.D. Student Department of Psychology University of Michigan MedicalResearch.com: What is the background for this study? Response: From the common cold to COVID-19, people get sick all the time. Because our social worlds don’t pause just because we are feeling ill, we often still need to navigate in-person events ranging from work and school to first dates and family dinners even while we’re feeling under the weather. In these kinds of social situations, do we always tell others when we’re feeling sick, or are there times when we may want to downplay our illness? After all, we tend to react negatively to, find less attractive, and steer clear of people who are sick with infectious illness. To the extent that we want to avoid these negative social outcomes while sick, it therefore makes sense that we may take steps to cover up our sickness in social situations. Given that this concealment could serve individual social goals (like allowing you to connect with others) at the cost of broader harms to public health (through the spread of infectious disease), we found this behavior both theoretically novel and practically timely.

Abuse and Neglect, Author Interviews, Gender Differences, Genetic Research, Science, University of Michigan / 05.01.2024

MedicalResearch.com Interview with: Jianzhi "George" ZhangMarshall W. Nirenberg Collegiate ProfessorDepartment of Ecology and Evolutionary BiologyUniversity of MichiganAnn Arbor, MI 48109-1085 MedicalResearch.com: What is the background for this study? Response: A few percent of humans perform same-sex sexual behavior (SSB), a trait that is partially heritable. Because SSB leads to fewer children, the stable maintenance of SSB-associated alleles in populations has been a long-standing Darwinian paradox. A number of hypotheses have been proposed to resolve this paradox, but most of them lack clear empirical evidence. One version of the antagonistic pleiotropy hypothesis posits that SSB-associated alleles are subject to heterosexual advantage. Specifically, it was found that SSB-associated alleles are associated with more sexual partners when in heterosexuals (individuals of exclusive opposite-sex sexual behavior), which could lead to more offspring, potentially compensating the reduced reproduction of SSB individuals. While the above mechanism has likely worked in premodern societies, our recent study (PNAS 2023) found that it is no longer working in the modern United Kingdom, because the widespread use of contraception has decoupled the number of offspring from the number of sexual partners in heterosexuals.

Allergies, Author Interviews, Dermatology, University of Michigan / 16.11.2023

MedicalResearch.com Interview with: Charles Schuler, MD Assistant Professor Allergy and Clinical Immunology & Mary H. Weiser Food Allergy Center University of Michigan MedicalResearch.com: What is the background for this study? Response: Anaphylaxis is a severe allergic reaction that may include a skin rash, nausea, vomiting, difficulty breathing, and shock. Food anaphylaxis sends 200,000 people to the emergency room annually in the United States. Oral food challenges are when a patient ingests increasing doses up to a full serving of the suspected food allergen under supervision of a medical provider, usually an allergist. These oral food challenges are the diagnostic standard for food allergy/anaphylaxis as skin and blood allergy tests have high false positive rates. Although a highly accurate test, patients often experience anaphylaxis during oral food challenges necessitating an epinephrine injection. (more…)
ADHD, Author Interviews, JAMA, Pediatrics, University of Michigan / 18.04.2023

MedicalResearch.com Interview with: Sean Esteban McCabe, PhD Director, Center for the Study of Drugs, Alcohol, Smoking and Health Department of Health Behavior and Biological Sciences University of Michigan School of Nursing Ann Arbor, MI MedicalResearch.com: What is the background for this study? Response: Prescription stimulant therapy for ADHD helps millions of people, including in my own family, and students, friends and colleagues. It's critical to balance the need for access to these medications while reducing the risk for misuse. This is more important than ever now because there have been recent increases in the prescribing of stimulant therapy for ADHD. There is a need to understand the prevalence of stimulant therapy for ADHD and prescription stimulant misuse in U.S. middle and high schools. (more…)
Author Interviews, Biomarkers, Heart Disease, JACC, University of Michigan / 21.12.2022

MedicalResearch.com Interview with: Salim S. Hayek MD Assistant Professor Medical Director of the Frankel Cardiovascular Center Clinics University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Essentially, immune checkpoint myocarditis is a rare but deadly complication of immune checkpoint inhibitors – amazing drugs that are increasingly used for the treatment of various cancers. Most patients present late, and when they do, they’re very ill and have a 50% chance of death. Diagnosing ICI myocarditis is challenging, given there is no one test that can differentiate it from other causes of cardiac injury. It is important to diagnose it fast, early and accurately in order to start immunosuppressive therapy as soon as possible. What we did in this study was look at commonly measured biomarkers in all patients receiving ICI at the University of Michigan. What we found was that patients who developed ICI myocarditis had early signs of muscle destruction (rise in CPK) levels and hepatitis (rise in AST, ALT), and that all patients who had myocarditis with bad outcomes had rises in all of the aforementioned biomarkers. Creatinine phosphokinase was the most sensitive. (more…)

MedicalResearch.com Interview with: Meilan K Han MD, MS Henry Sewall Professor of Medicine Professor of Internal Medicine and Section Head Division of Pulmonary and Critical Care Medicine, Medical School University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: In the NIH sponsored SPIROMICS study we demonstrated that symptomatic, tobacco exposed individuals have frequent exacerbations. Many of these individuals are treated with the same inhaled medications that have shown benefit in COPD, but we don’t have any evidence basis for this practice. (more…)
Author Interviews, Cancer Research, Nature, Pancreatic, University of Michigan / 03.06.2022

MedicalResearch.com Interview with: Imad Shureiqi, MD, MS Professor, Division of Hematology and Oncology Department of Internal Medicine Rogel Cancer Center Ann Arbor, MI, 48109 MedicalResearch.com:  What is the background for this study?   Response: Pancreatic ductal adenocarcinoma is a highly lethal form of cancer with rising occurrence, and strategies to prevent and treat the disease are urgently needed. Most cases of pancreatic cancer arise from pre-cancerous lesions called pancreatic intraepithelial neoplasia (PanIN); about 55-80% of adults over forty are estimated to have these low-grade pre-cancerous silent pancreatic lesions. But critical factors that promote the progression of pancreatic pre-cancerous lesions to pancreatic cancer remain poorly defined, especially those easy to target. Findings from this publication indicate that people who have silent PanIN pre-cancerous lesions, even those that are low-grade, could increase their risk of PanIN progression into pancreatic cancer by consuming activators of a nuclear lipid receptor called peroxisome proliferator-activated receptor-delta (PPARδ). PPARδ activators can be natural substances, such certain fatty acids like palmitic and arachidonic acid in high-fat diets, or synthetic ones, like Cardarine (GW501516). (more…)
Alzheimer's - Dementia, Author Interviews, Cognitive Issues, Obstructive Sleep Apnea, Pulmonary Disease, University of Michigan / 16.04.2021

MedicalResearch.com Interview with: Galit Levi Dunietz  MPH, PhD Assistant Professor

Tiffany Braley, MD, MS Associate Professor

University of Michigan, Medical School Department of Neurology Department of Nutritional Sciences Ann Arbor, MI 48109-5845 MedicalResearch.com: What is the background for this study? Response: Dementia is a public health crisis that affects more than 6 million Americans.  As no treatments to effectively reverse dementia are currently available, interest has shifted toward modifiable risk factors for dementia, which may offer a critical window for prevention or intervention. Recent research suggests that obstructive sleep apnea (OSA) is a common, yet undiagnosed, risk factor for cognition impairment in older adults. However, few studies have examined whether treatment of OSA with positive airway pressure (PAP) therapy could protect those with OSA against developing dementia, says principal investigator, Dr. Tiffany Braley, MD, MS, Associate Professor of Neurology from the University of Michigan. To address this gap, Dr. Braley and Dr. Galit Levi Dunietz, PhD, MPH, Assistant Professor and sleep epidemiologist, examined associations between PAP therapy use and 3-year incidence of Alzheimer’s disease, mild cognitive impairment (MCI), or other forms of dementia (DNOS, “dementia not otherwise specified”).

AHA Journals, Author Interviews, Heart Disease, University of Michigan / 17.11.2020

MedicalResearch.com Interview with: Sara Saberi, MD, MS Assistant Professor Inherited Cardiomyopathy Program Frankel Cardiovascular Center University of Michigan Hospital Michigan Medicine MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by HCM? How common is it and whom does it affect? Response: HCM is short for hypertrophic cardiomyopathy, the most common genetic myocardial disorder. It occurs in 1:500 people worldwide and because it is inherited in an autosomal dominant fashion, it affects men and women equally. HCM is characterized by unexplained left ventricular (LV) hypertrophy, hypercontractility, myofibrillar disarray and myocardial fibrosis with associated abnormalities in LV compliance and diastolic function. In some patients, there is progressive adverse cardiac remodeling, associated with chronic heart failure and atrial fibrillation as a result of diastolic dysfunction, left ventricular outflow tract (LVOT) obstruction, or less commonly, LV systolic dysfunction. Current medical management of obstructive HCM (oHCM) is limited to the use of beta blockers and non-dihydropyridine calcium channel blockers, or disopyramide, none of which have been shown to modify disease expression or outcomes after onset. Mavacamten is a first-in-class, small molecule, selective inhibitor of cardiac myosin specifically developed to target the underlying pathophysiology of HCM by reducing actin–myosin cross-bridge formation. The phase 3 EXPLORER-HCM trial showed that mavacamten improved exercise capacity, LVOT gradients, symptoms, and health status compared with placebo in patients with symptomatic oHCM. At selected study sites, participants were enrolled in a cardiac magnetic resonance (CMR) imaging substudy. CMR is the gold standard for measurement of ventricular mass, volumes and noninvasive tissue characterization, making it an ideal imaging modality to assess the effect of mavacamten on cardiac structure and function in patients with HCM.

Aging, Author Interviews, Cost of Health Care, JAMA, University of Michigan / 10.02.2020

MedicalResearch.com Interview with: Renuka Tipirneni, MD, MSc, FACP Assistant Professor Holder of the Grace H. Elta MD Department of Internal Medicine Early Career Endowment Award 2019-2024 University of Michigan Department of Internal Medicine Divisions of General Medicine and Hospital Medicine and Institute for Healthcare Policy & Innovation Ann Arbor, MI 48109 MedicalResearch.com: What is the background for this study? Response: While U.S. adults age 50-64 previously had more limited options for health insurance before Medicare at age 65, the Affordable Care Act expanded the number of options, including Marketplace plans (e.g., through HealthCare.gov) and Medicaid. This expanded set of options may complicate decisions about health insurance near retirement. In addition, several policy challenges to the Affordable Care Act may add uncertainty to the decision-making process. (more…)

MedicalResearch.com Interview with: Kyle Sheetz, MD Clinical Year 4 Resident, General Surgery Michigan Medicine MedicalResearch.com: What is the background for this study? Response: There are concerns that robotic surgery is increasing for common surgical procedures with limited evidence and unclear clinical benefit. Prior studies describing the use of robotic surgery relied upon claims or billing data to identify robotic operations from laparoscopic or open ones. This may lead to inaccuracies as claims data may not provide specific codes for robotic operations. (more…)
Author Interviews, JAMA, Opiods, Pediatrics, University of Michigan / 19.12.2019

MedicalResearch.com Interview with: Kao-Ping Chua, MD PhD Assistant Professor, Department of Pediatrics Susan B. Meister Child Health Evaluation and Research Center University of Michigan MedicalResearch.com: What is the background for this study? Response: Opioids are frequently prescribed to adolescents and young adults aged 12-21 years – in a recent study, 1 in 8 patients in this population were prescribed opioids during the year. At the same time, almost 30% of the 3000 opioid-related overdose deaths in 2016 among adolescents and young adults involved prescription opioids. Given the frequency of opioid prescribing and the risk of overdose, it is important to understand how to prescribe opioids safely to adolescents and young adults. However, there have been few studies that examine which opioid prescribing patterns are associated with prescription opioid overdose in adolescents and young adults. Prior studies examining these patterns have focused on older adults, particularly U.S. Veterans, so the generalizability of these findings to younger populations is unclear. (more…)
Author Interviews, Education, University of Michigan / 18.10.2019

MedicalResearch.com Interview with: Chithra R. Perumalswami, MD, MSc Research Fellow Center for Bioethics & Social Sciences in Medicine University of Michigan  Reshma Jagsi, MD, DPhil Professor, Deputy Chair, and Residency Program Director Department of Radiation Oncology and Director Center for Bioethics and Social Sciences in Medicine University of Michigan MedicalResearch.com: What is the background for this study? Response: Burnout is a syndrome characterized by a sense of decreased personal accomplishment, emotional exhaustion, and depersonalization. It can lead to increased depression, illness, suicide, and absences from work. Physician burnout has reached epidemic proportions and physician-scientists are not immune from it. They are a critical part of the healthcare workforce who are responsible for translating innovative bench research to the bedside of patients, and in recent years have faced increasing pressures.  (more…)
Author Interviews, Pediatrics, University of Michigan, Vitamin D / 21.08.2019

MedicalResearch.com Interview with: Eduardo Villamor, M.D., M.P.H., Dr.P.H. Professor, Epidemiology School of Public Health University of Michigan Ann Arbor, Michigan MedicalResearch.com: What is the background for this study? Response: Vitamin D deficiency has been related to adverse mental health outcomes, including depression and schizophrenia, in adults.  Some studies have suggested a potential role of vitamin D status prenatally on other neurodevelopmental outcomes in childhood.  However, few studies had extended into adolescence which is the life period when certain mental health issues that predict disease later in life, namely behavioral problems, first appear.  (more…)
Author Interviews, JAMA, Outcomes & Safety, Surgical Research, University of Michigan / 15.08.2019

MedicalResearch.com Interview with: Kyle Sheetz, MD, MSc Research Fellow Center for Healthcare Outcomes and Policy University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Various patient safety organizations and clinical societies continue to advocate for volume thresholds as a means to improve the short-term safety and overall effectiveness of high risk cancer surgeries in the United States. We asked two questions with this study: 1) What proportion of U.S. hospitals meet discretionary volume standards? 2) Do these standards differentiate hospitals based on short-term safety outcomes (mortality and complications)? We found that a relatively low proportion of hospitals meet even modest volume standards put forth by the Leapfrog Group. These standards did not differentiate hospitals based on outcomes for 3 of 4 high risk cancer operations reported by the Leapfrog Group. However, using higher thresholds, we were able to demonstrate a significant relationship between higher hospital volume and better outcomes, which has been reported numerous times. (more…)
Author Interviews, HIV, University of Michigan / 15.07.2019

MedicalResearch.com Interview with: Rogério Meireles Pinto, LCSW, Ph.D. Professor and Associate Dean for Research University of Michigan School of Social Work MedicalResearch.com: What is the background for this study? Response: In order to decrease the rate of HIV infection, interventions to scale up PrEP will need to address identified barriers at multiple ecological levels. In the past decade, interventions proposed to address PrEP implementation barriers were limited to one ecological level or another (e.g., individual or community). The failure to consider interventions targeting multiple ecological levels simultaneously may help explain why PrEP implementation is lagging. This failure is also due to methodological limitations of PrEP implementation studies.This high-quality paper presents a thorough and theoretically grounded review of original research on HIV Pre-Exposure Prophylaxis (PrEP) implementation in the U.S. (more…)

MedicalResearch.com Interview with: Valerie M. Vaughn, MD MSc Assistant Professor of Medicine and Research Scientist, Division of Hospital Medicine The Patient Safety Enhancement Program and Center for Clinical Management Research Michigan Medicine and the Ann Arbor VA Medical Center  MedicalResearch.com: What is the background for this study? Response: Pneumonia is one of the top causes for hospitalization and one of the main reasons for antibiotic use in US hospitals. In the past decade, studies have suggested that patients can be safely treated with short course antibiotic therapy instead of the prolonged courses we used to prescribe. Our study looked at prescribing practices in 43 hospitals across the state of Michigan to see if we were appropriately prescribing short course therapy, and if so, how that affected patients. (more…)
Addiction, Author Interviews, JAMA, Opiods, University of Michigan / 30.06.2019

MedicalResearch.com Interview with: Rebecca L. Haffajee, J.D., Ph.D., M.P.H. Assistant Professor Department of Health Management & Policy umichsphumichsph MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Evidence suggests that the availability of medications to treat opioid use disorder (OUD) has been slow to expand, particularly in rural areas, despite the efficacy and effectiveness of these medications in reducing overdose deaths and other adverse life outcomes. We were interested in understanding the characteristics of counties both with high need (as measured by above-national rates in opioid overdose deaths) AND low provider capacity to deliver medications to treat OUD in 2017. We found that such "opioid high-risk" counties were likely to be in the East North Central (e.g., Michigan, Ohio, Illinois, Indiana), South Atlantic (e.g., North Carolina, South Carolina, Virginia, West Virginia), and Mountain (e.g., New Mexico, Arizona, Nevada) regions. We also found that these opioid high-risk counties were more likely to have higher rates of unemployment and less likely to have fewer primary care clinicians or be micropolitan (more…)
Author Interviews, Geriatrics, JAMA, Ophthalmology, University of Michigan / 21.06.2019

MedicalResearch.com Interview with: Joshua R. Ehrlich, MD, MPH Assistant Professor, Ophthalmology and Visual Sciences Kellogg Eye Center Department of Ophthalmology and Visual Sciences University of Michigan  MedicalResearch.com: What is the background for this study?   Response: This study came out of data collected as part of the National Poll on Healthy Aging (NPHA). The NPHA is funded by AARP and the Institute for Healthcare Policy and Innovation at the University of Michigan to inform the public, healthcare providers, and policymakers on a variety issues related to health. The vision survey, conducted in March 2018, was just one of many NPHA surveys. Due to aging of the population, the number of older U.S. adults with blindness and vision impairment is expected to double over the next 30 years. Thus, this study was designed to provide crucial data  on contemporary data on patterns of eye care utilization in older adults. (more…)

MedicalResearch.com Interview with: Dr. Mark R. Hemmila MD Associate Professor of Surgery Division of Acute Care Surgery University of Michigan  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Traumatic injury has a tendency to be thought of as a disease that preferentially impacts younger people.  We wanted to explore the prevalence and impact of traumatic injury within the population of patients for whom Medicare is the third party payer.  (more…)
Author Interviews, JAMA, Opiods, Primary Care, University of Michigan / 11.05.2019

MedicalResearch.com Interview with: Kao-Ping Chua, M.D., Ph.D. Department of Pediatrics Susan B. Meister Child Health Evaluation and Research Center University of Michigan, Ann Arbor MedicalResearch.com: What is the background for this study?   Response: Doctor and pharmacy shopping is a high-risk behavior in which patients obtain opioid prescriptions from multiple prescribers and fill them at multiple pharmacies. Because this behavior is associated with a high risk of overdose death, there have been many efforts to help clinicians detect doctor and pharmacy shopping among patients prescribed opioids. For example, 49 states have a prescription drug monitoring program that provides information on patients’ prior controlled substance prescriptions. In contrast, there has been little attention to the possibility that patients prescribed opioids may have family members who are engaged in opioid doctor and pharmacy shopping. Such family members may divert opioids prescribed to patients because of their access to these opioids. (more…)

MedicalResearch.com Interview with: Diane Harper, M.D., M.P.H., M.S. Professor of Family Medicine and Obstetrics and Gynecology Senior Associate Director, Michigan Institute for Clinical and Health Research Physician Director for Community Outreach, Engagement and Health Disparities, Rogel Cancer Center Michigan Medicine  MedicalResearch.com: What is the background for this study? Response: There is no current cure for women with HPV infection that has progressed to CIN 2/3 disease. The only treatment is for the diseased cervix, and does not eliminate the risk of another CIN 2/3 from the HPV infection 15-20 years later. This vaccine is made from a live virus that has 3 genes inserted:  human cytokine IL-2, and modified forms of HPV 16 E6 and E7 proteins. When the vaccine is injected subcutaneously, the proteins for HPV 16/E6 and E7 and the cytokine LI-2 proteins are made. These proteins trigger the immune response.  This is very different form imiquimod which is topical and not specific for HPV. (more…)
Author Interviews, Flu - Influenza, Infections, PLoS, University of Michigan / 25.01.2019

MedicalResearch.com Interview with: Betsy Foxman PhD Hunein F. and Hilda Maassab Endowed Professor of Epidemiology Director, Center for Molecular and Clinical Epidemiology of Infectious Diseases Ann Arbor, Michigan 48109-2029 MedicalResearch.com: What is the background for this study? Response: Influenza is a major cause of human illness and death worldwide. Vaccines are the best available means of prevention. However, vaccine effectiveness has been low to moderate in recent years and coverage remains low in many countries. There is increasing evidence suggesting the microbiome plays an important role in shaping host immunity and may be a potential target for reducing disease. In our study, we used a household transmission study to explore whether the respiratory microbiome was associated with influenza susceptibility.  (more…)
Author Interviews, Cannabis, University of Michigan / 17.01.2019

MedicalResearch.com Interview with: Daniel J. Kruger, PhD Research Assistant Professor University of Michigan MedicalResearch.com: What is the background for this study? Response: We study health-related behaviors, such as diet and the consumption of caffeine and alcohol. Given the recent trends in legalization of cannabis for medical and even recreational purposes, we were concerned with the narrow focus of current public health efforts regarding cannabis. Although some in the field take a harm-reduction approach to substance use, too many efforts focus solely on abstinence. These programs are a legacy from the era of prohibition, and we know that there are disadvantages to such a restricted scope in public health. For example, municipalities that eliminated or blocked accurate and effective sex education had increases in teenage pregnancy rates. There are so many public health-related aspects of cannabis, beyond risks and adverse effects, which need to be addressed by systematic scientific research. Because of the legal history of cannabis, there is little integration with the mainstream health care system. The focus of the current study was investigating how medical cannabis users perceived medical cannabis in comparison to pharmaceutical drugs and other aspects of the mainstream health care system and how they navigated they relationships between these currently separate systems (more…)
Author Interviews, NEJM, Pediatrics, Smoking, Tobacco, Tobacco Research, University of Michigan / 30.12.2018

MedicalResearch.com Interview with: Richard Miech Ph.D Professor Principal Investigator, Monitoring the Future Institute for Social Research University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Every year Monitoring the Future conducts a survey to examine trends in adolescent substance use.  We draw a random sample of schools from a list of all schools in the United States and conduct our survey in ~400 schools.  Our survey is representative of U.S. 8th, 10th, and 12th grade students.  In other words, our results are what you would find if you surveyed every single 8th, 10th, and 12th graders in the United States, within the bounds of a small sampling error of a few percentage points. An increase in vaping is the big news for 2018.  In 10th and 12th grade the increase in nicotine vaping was the largest we've ever seen for any substance in the past 43 years.  As a result of this increase in nicotine vaping, overall use of nicotine increased as well, which suggests that vaping is drawing youth into nicotine use.  We also saw a significant increase in marijuana vaping.

Elta MD Department of Internal Medicine Early Career Endowment Award 2019-2024 University of Michigan Department of Internal Medicine Divisions of General Medicine and Hospital Medicine, and Institute for Healthcare Policy & Innovation Ann Arbor, MI 48109 MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Navigating health insurance and health care choices is challenging and requires significant health insurance literacy (knowledge and application of health insurance concepts). We looked at the association between U.S. adults' health insurance literacy and avoidance of health care services due to perceived cost. We found that 30% of people we surveyed reported delayed or foregone care because of perceived cost, and that those with lower health insurance literacy reported significantly greater avoidance of both preventive and nonpreventive health care services.

Author Interviews, JAMA, Opiods, Surgical Research, University of Michigan / 07.11.2018

MedicalResearch.com Interview with: Joceline Vu, MD Resident, PGY-5 Department of Surgery University of Michigan  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This study examined how much opioid patients use after surgery, and looked at factors that might predispose some patients to use more or less. Patient opioid use after surgery is an interesting question that’s gained a lot of attention recently, because it’s different from other uses for opioids. If you have chronic pain, you’re probably going to use all of your prescription. But if you have surgery, you may not take all of your pills, and this leaves people with leftover pills that can be dangerous later. From this study, we found that patients only use, on average, about quarter of their prescription, meaning that a lot of them are left with leftover pills. Moreover, we found that the biggest determinant of how much they used wasn’t how much pain they reported, or any other factor—it was how big their original prescription was. What this means is that opioid use after surgery isn’t just determined by pain, but also by what surgeons prescribe. It’s important to keep this in mind as we try to reduce unnecessary opioid prescribing after surgical procedures.  (more…)
