MedicalResearch.com Interview with: Paul Dinneen Loprinzi, PhD Health, Exercise Science and Recreation Management University of Mississippi MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research demonstrates that adults who have higher daily sedentary behavior tend to have worse cardiometabolic health profiles. The extent to which sedentary behavior is associated with diabetic retinopathy has yet to be evaluated in the literature before our study. Our findings provided some suggestive evidence that more sedentary behavior was associated with a higher odds of having diabetic retinopathy. (more…)

MedicalResearch.com Interview with: Prof. Peter Nordström PhD Department of Community Medicine and Rehabilitation Geriatrics, Umeå University Umeå, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: Numerous studies has shown an association between BMI, CVD and death. However, it is not known to what extent genetic factors influence this relationship. We used over 4000 monozygous twin pairs that had different BMI. This mean that the difference in BMI must be due to environmental factors since the genetic setup is similar in monozygous twins. Since the fatter twin did not have a higher risk of myocardial infarction (MI) or death, environmental factors that increase BMI is very unlikely to increase the risk of myocardial infarction or death. By inference the strong association between BMI, MI and death must be explained by the fact that the same genes control both obesity, MI and death. By contrast, the fatter twin had a higher risk of diabetes. (more…)
Author Interviews, Brigham & Women's - Harvard, Electronic Records, JAMA, Outcomes & Safety / 04.08.2016

MedicalResearch.com Interview with: Stephanie Mueller, MD MPH FHM Division of General Medicine Brigham and Women's Hospital Boston, MA 02120 MedicalResearch.com: What is the background for this study?  Response: Failures in communication among healthcare personnel are known threats to patient safety, and occur all too commonly during times of care transition, such as when patient care responsibility is transferred from one provider to another (i.e., handoff). Such failures in communication put patients at risk for adverse outcomes. (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Nutrition, Protein, Vegetarians / 02.08.2016

MedicalResearch.com Interview with: Mingyang Song Sc.D, research fellow Clinical and Translational Epidemiology Unit and Division of Gastroenterology MGH and Department of Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies have been focused on the amount of protein intake, while little is known regarding the health effect of different food sources for protein intake. In this study, we found that high animal protein intake was associated with higher mortality, whereas high plant-based protein was associated with lower mortality. Replacement of animal protein with plant protein was associated with lower mortality. Overall, the findings support the importance of food sources for protein intake for long-term health outcomes.

Author Interviews, Brain Injury, JAMA, Pediatrics / 02.08.2016

MedicalResearch.com Interview with: Danny G. Thomas, MD, MPH Department of Pediatrics, Emergency Medicine Children’s Hospital of Wisconsin Corporate Center Milwaukee, WI MedicalResearch.com: What is the background for this study? What are the main findings? Response: This was a secondary analysis of a randomized controlled trial of strict rest after concussion published last year. We wanted to find out how mental and physical activity levels related to symptom spikes or sudden increases in concussion symptoms. We found that one in three patients had symptoms spikes in recovery. Patients who had symptom spikes tended to have higher symptoms in the emergency department and throughout recovery. Most symptom spikes were not associated with an increase in physical and mental activity level the day prior. We did find that a sudden increase in activity like returning to school did increase the risk of having a symptom spike, but the good news is these symptom spikes seemed to resolve the following day and did not impact recovery by 10 days.

Author Interviews, Gastrointestinal Disease, Genetic Research, JAMA / 29.07.2016

MedicalResearch.com Interview with: Amitabh Chak, MD University Hospitals Case Medical Ctr Cleveland, OH, 44106 MedicalResearch.com: What is the background for this study? What are the main findings? Response: About 20 years ago we discovered that Barrett's esophagus and esophageal cancer aggregate in a small proportion of families suggesting there might be a genetic basis to these complex diseases. As we started looking at these families, we identified a rare family with multiple members who had Barrett's esophagus and multiple members who had passed away from esophageal cancer at a young age. Advances in exome sequencing have now allowed us to identify a mutation in a gene whose function is not known that predisposes this family to develop Barrett's esophagus. Functional studies suggest that this gene, VSIG10L, is involved in maturation of normal squamous esophagus. (more…)
Author Interviews, JAMA, Melanoma / 29.07.2016

MedicalResearch.com Interview with: Dr. Michael Pignone MD MPH Task Force member Professor of medicine and Inaugural Chair Department of Internal Medicine Dell Medical School The University of Texas at Austin. Editor’s note: Dr. Pignone discusses the recent US Preventive Services Task Force Recommendation Statement on the effectiveness of screening for skin cancer with a clinical visual skin examination MedicalResearch.com: What is the background for this recommendation? How Does the USPSTF Grade Preventive Services? Response: The Task Force’s primary concern is the health of Americans, and all of our recommendations are based on an assessment of the evidence of both the benefits and harms of a particular preventive service. For this recommendation statement, we looked at all available evidence on a visual skin exam, including studies of exams conducted by both primary care clinicians and dermatologists, to see how effective this exam was at preventing death from skin cancer. Unfortunately, there is not enough evidence to know with certainty whether or not a visual skin exam leads to a reduction in death from skin cancer, which resulted in the Task Force issuing an I statement. The Task Force encourages more research that could provide future evidence on the effectiveness of visual screening to prevent death from skin cancer. (more…)
Author Interviews, Breast Cancer, JAMA, Technology / 29.07.2016

MedicalResearch.com Interview with: Lauren P. Wallner, PhD, MPH Assistant Professor, Departments of Medicine and Epidemiology University of Michigan Ann Arbor, MI MedicalResearch.com: What is the background for this study? What are the main findings? Response: Online communication tools like email and social media could be used to support patients through their cancer treatment decision making and ongoing care. Yet, we know very little about whether and how newly diagnosed cancer patients use these tools and whether using online communication influences patients appraisals of their treatment decision making process. We surveyed 2,460 women with newly diagnosed breast cancer as part of the iCanCare Study about their use of email, texting, social media and web-based support groups following their diagnosis. Our findings suggest that women who more often used these online communication tools deliberated more about their surgical treatment and were more satisfied with their treatment decision. However, the use of social media in this diverse population was lower than we expected (12%), and was less common in older women, those with less education, and Black and Latina women. (more…)
Author Interviews, Cost of Health Care, Health Care Systems, JAMA, Surgical Research / 28.07.2016

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.

Author Interviews, JAMA, Schizophrenia / 26.07.2016

MedicalResearch.com Interview with: Professor Jayashri Kulkarni MBBS, MPM, FRANZCP, PhD Director, Monash Alfred Psychiatry research centre Vic Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Schizophrenia is a complex psychiatric disorder and many patients are not able to achieve remission on the available treatments. There are clear sex differences in many aspects of the illness, which not only implicates a role for the sex hormone estrogen in schizophrenia, but also highlights the need for sex-specific treatments. Our group has conducted many clinical trials using adjunctive estradiol treatment, with excellent improvement in psychotic symptoms- however, there can be physical side effects with longer term estradiol use. Raloxifene and other selective estrogen receptor modulators ( SERMs) - the so-called "brain estrogens", with their more specific brain impacts and less body side effects - provide an option to use longer term estrogen in people with refractory schizophrenia. We conducted the first ever pilot study of raloxifene in 2010, and now present findings from a bigger study of adjunctive raloxifene treatment in schizophrenia. (more…)

MedicalResearch.com Interview with: Dr. Katherine Nelson MD Staff Paediatrician with the Paediatric Advanced Care Team at SickKids and PhD student University of Toronto MedicalResearch.com: What is the background for this study? Response: Trisomy 13 and 18 are rare genetic conditions that cause problems in multiple organ systems, including heart defects and severe neurologic impairment.  A majority of children with trisomy 13 and 18 die in the first days to weeks after birth, though a small number survive beyond one year.  For years, health care providers have debated the effectiveness and ethics of surgical interventions in these populations.

Author Interviews, Cannabis, JAMA, Pediatrics / 25.07.2016

MedicalResearch.com Interview with: George Sam Wang MD FAAP Assistant Professor of Pediatrics Section of Emergency Medicine, Medical Toxicology Department of Pediatrics University of Colorado Anschutz Medical Campus Children's Hospital Colorado MedicalResearch.com: What is the background for this study? Response: Many states have allowed medical and now recreational marijuana. The impact on pediatric population has not been fully described. MedicalResearch.com: What are the main findings? Response: Unintentional exposures presenting to our children's hospital and calls to our regional poison center significantly increased after our state allowed recreational marijuana. MedicalResearch.com: What should readers take away from your report? Response: Exposures in children are increasing in our state that allows medical and recreational Marijuana, many were edible products. Marijuana products should be treated like medications and household products in home and properly and safely stored. States looking to legalize marijuana need to consider safety rules and regulations during rule making processes. (more…)
Author Interviews, Health Care Systems, JAMA, Stroke / 25.07.2016

MedicalResearch.com Interview with: Kimon Bekelis, MD Chief Resident Department of Neurosurgery Dartmouth-Hitchcock School of Medicine MedicalResearch.com: What is the background for this study? Response: Physicians often must decide whether to treat acute stroke patients locally, or refer them to a more distant Primary Stroke Center (PSC). There is little evidence on how much the increased risk of prolonged travel time offsets benefits of specialized  Primary Stroke Center care. (more…)
Author Interviews, Cost of Health Care, JAMA / 25.07.2016

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, JAMA, Johns Hopkins, Race/Ethnic Diversity, Stroke / 25.07.2016

MedicalResearch.com Interview with: Romanus Roland Faigle, M.D., Ph.D. Assistant Professor of Neurology The Johns Hopkins Hospital MedicalResearch.com: What is the background for this study? Response: Stroke care entails a variety of procedures and interventions, which generally fall into one of the two following categories: 1) curative/preventative procedures (such as IV thrombolysis and carotid revascularization), which intent to prevent injury and restore function; and 2) life-sustaining procedures (such as gastrostomy, mechanical ventilation, tracheostomy, and hemicraniectomy), which intent to address complications from a stroke and to prevent death. The use of curative/preventative procedures is supported by excellent evidence and is guided by well-defined criteria, while those are largely lacking for life-sustaining procedures. Therefore, curative/preventative are desirable for eligible patients, while life-sustaining procedures indicate the need to address undesired complications and in itself have questionable utility. We wanted to determine whether race differences in the use of the individual stroke-related procedures exist, and whether presence and directionality of differences by race follow a pattern unique to each of the 2 procedure groups. (more…)
Author Interviews, Infections, JAMA / 25.07.2016

MedicalResearch.com Interview with: Dr. Ane Uranga MD Department of Pneumology, Galdakao-Usansolo Hospital Galdakao, Bizkaia, Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite clear benefits of shorter antibiotic treatments, reducing the duration of treatment remains challenging in daily clinical practice. Actually, IDSA/ATS recommendations for Community Acquired Pneumonia (CAP) suggested a minimum of 5 days of treatment based on clinical stability criteria. However, in our study the median of duration of antibiotic treatment in the control group was as high as 10 days. The main finding is that receiving 5 days antibiotic treatment in hospitalized patients suffering from CAP is not inferior to arbitrary treatment schedules in terms of clinical success. (more…)
Author Interviews, Dermatology, JAMA / 22.07.2016

MedicalResearch.com Interview with: G. Thomas (Tom) Ray Division of Research, Kaiser Permanente 2000 Broadway Oakland, CA 94612-2304 MedicalResearch.com: What is the background for this study? Response: Basal cell carcinoma (BCC) is the most common cancer in the United States. BCCs tend to develop on sun-exposed areas such as the head and neck and are typically treated with various surgical techniques in an outpatient setting. Although BCCs are rarely fatal, they have been estimated to be among the most costly cancers in the Medicare population due to their high incidence. Yet because these cancers are not tracked by national registries the way, for example, melanoma is, basal cell carcinomas have been difficult to study. Incidence rates in the past have tended to rely on surveys such as those by the National Cancer Institute. And studies using disease codes have, until recently, been difficult because the codes used for basal cell carcinoma and squamous cell carcinoma were the same. Since 1997, Kaiser Permanente Northern California (KPNC) has had computerized pathology results that allowed us to develop an internal registry of BCC cancers. In addition to having detailed information about basal cell cancer patients, we also had detailed information on the underlying population - KPNC members – which allowed us to determine incidence rates of BCC by age, sex, and most importantly for this study, by geographic location. This is because we know the residential location of all KPNC members at any given time – both those that get basal cell cancer and those who do not. This combination of a validated BCC registry with a well-defined population at-risk gave us the unique ability to investigate the spatial distribution of BCC in Northern California and assess whether there existed geographic clustering of basal cell cancers. Although the investigation of spatial clustering of other cancers is fairly common, no such analyses have been performed for basal cell cancer in the United States. (more…)

MedicalResearch.com Interview with: Harrison W. Lin, M.D. Assistant Professor Department of Otolaryngology-Head & Neck Surgery UC Irvine Medical Center Orange, CA 92868 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We reviewed the data from the Integrated Health Interview Series, which is a project funded by the National Institutes of Health to supplement the National Health Interview Survey (NHIS), a household-based, personal interview survey administered by the US Census Bureau and Centers for Disease Control and Prevention since 1957. The NHIS serves as the largest source of health information in the civilian population of the United States. Analyzing the available data on tinnitus symptoms from this survey, we found that approximately 1 in 10 Americans have chronic tinnitus. Moreover, durations of occupational and leisure time noise exposures correlated with rates of tinnitus – people who reported higher rates of loud noise exposures at work and recreationally more frequently reported chronic tinnitus. Finally, health care providers provided advice and treatment plans to patients with chronic tinnitus that were infrequently in line with the clinical practice guidelines published by the American Academy of Otolaryngology-Head & Neck Surgery Foundation.

Author Interviews, Diabetes, Heart Disease, JAMA / 21.07.2016

MedicalResearch.com Interview with: Dr Fiona Bragg Clinical Research Fellow Clinical Trial Service Unit and Epidemiological Studies Unit Nuffield Department of Population Health University of Oxford MedicalResearch.com: What is the background for this study? Response: Diabetes is known to be a risk factor for cardiovascular disease. It is less clear, however, whether higher blood glucose levels in individuals without diabetes are also associated with higher risk for cardiovascular diseases. It is important to examine this association because it may help us to understand the mechanisms underlying these diseases as well as appropriate approaches to preventing them. We therefore looked at this association in the China Kadoorie Biobank study of 0.5 million Chinese adults, examining the relationship between blood glucose levels and the subsequent risk for cardiovascular diseases among participants with no history of diabetes at the time of recruitment to the study.

Author Interviews, JAMA, Surgical Research / 21.07.2016

MedicalResearch.com Interview with: Dr. David A. Hyman, MD Division of Otolaryngology–Head and Neck Surgery Department of Surgery University of Wisconsin School of Medicine and Public Health Madison MedicalResearch.com: What is the background for this study? What are the main findings? Response: Motor vehicle collisions represent a significant source of facial fractures seen at US trauma centers. In the last few decades there have been significant advances in airbag technology as well as a national legislative push regarding seat belt use which has led to increased safety device use. With these trends, we sought to assess the incidence of facial fractures in patients who present to US trauma centers as well as to analyze what effect restraint devices have on the likelihood of facial fractures after motor vehicle collisions. This analysis was performed using National Trauma Data Bank data from 2007-2012. We found the incidence of at least one facial fracture after a motor vehicle collision was 10.9% with nasal fracture being the most common facial fracture. Based on our analysis of more than 56 thousand patients with a facial fracture, we found that use of an airbag alone reduced the likelihood of a facial fracture by 18% while use of a seat belt alone reduced likelihood by 43%. Use of both reduced the likelihood of facial fractures in a crash by 53%. Younger age, male sex, and use of alcohol increased the likelihood of facial fracture. (more…)
Author Interviews, Diabetes, JAMA, Pediatrics / 20.07.2016

MedicalResearch.com Interview with: Andy Menke PhD Social & Scientific Systems, Inc. Silver Spring, MD, 20910 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Limited information was available on the prevalence of diabetes among adolescents in the US, particularly the percentage that are undiagnosed and unaware of the condition. We found that 0.8% of adolescents 12-19 years of age had diabetes and 18% had prediabetes. Of those with diabetes, 29% overall were unaware of it and this increased to 40% among Hispanic adolescents and 50% among non-Hispanic black adolescents. (more…)
Author Interviews, Breast Cancer, Fertility, JAMA, OBGYNE / 20.07.2016

MedicalResearch.com Interview with: Alexandra W. van den Belt-Dusebout, PhD Department of Epidemiology The Netherlands Cancer Institute The Netherlands MedicalResearch.com: What is the background for this study? Response: In vitro fertilization (IVF) is commonly used, but because of the relatively recent use of IVF, long-term breast cancer risk is not yet known. Female sex hormones have been shown to affect breast cancer risk. Because sex hormone levels during hormonal stimulation of the ovaries for IVF are up to 10 times higher than in natural cycles, IVF was expected to increase breast cancer risk. (more…)

MedicalResearch.com Interview with: Principal investigator A/Prof Suetonia Palmer PhD University of Otago, New Zealand Senior investigator Prof. Giovanni Strippoli MD, PhD, MPH, MM University of Sydney, Australia and Diaverum, Sweden MedicalResearch.com: What is the background for this study? Response: Network meta-analysis is a new technique that allows us to evaluate ALL medical therapies for a specific clinical problem. We wondered whether any of the usual drugs used to treat glucose levels in people with diabetes were safest or most effective. (more…)
Asthma, Author Interviews, Environmental Risks, JAMA / 18.07.2016

MedicalResearch.com Interview with: Sara Rasmussen PhD Student Johns Hopkins School of Public Health Department of Environmental Health Sciences Johns Hopkins Bloomberg School of Public Health Baltimore, Maryland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Residents of communities undergoing unconventional natural gas development (the “fracking” industry) and those nearby can be exposed to noise, light, vibration, heavy truck traffic, air pollution, social disruption, and anxiety related to rapid industrial development of one’s community. In Pennsylvania, development began in the mid-2000s and by 2012, 6,253 wells were drilled. In our study, we found increased odds of asthma hospitalizations, asthma emergency department visits, and asthma oral corticosteroid medication orders (a medication used for asthma exacerbations) among asthma patients residing near bigger or larger numbers of active unconventional natural gas wells compared to those residing farther away. (more…)
Author Interviews, Depression, JAMA, Mental Health Research, Pediatrics / 18.07.2016

MedicalResearch.com Interview with: Dr Carmen Pace MPsych (Clin Child) PhD AMACPA Clinical Psychologist and Research Fellow Murdoch Childrens Research Institute The Royal Children’s Hospital Flemington Rd Parkville, Victoria AUS MedicalResearch.com: What is the background for this study? Response: We know that mothers of very preterm infants (born prior to 32 weeks gestation) are at higher risk for psychological distress compared to mothers who have healthy full term infants. However, detailed longitudinal research looking at how symptoms evolve over the first weeks and months is limited, and fathers are largely neglected in the literature. We addressed these gaps by assessing symptoms of depression and anxiety in both mothers and fathers every two weeks for the first twelve weeks after birth, and again at six months. (more…)

Author Interviews, Geriatrics, JAMA, Surgical Research / 15.07.2016

MedicalResearch.com Interview with: Julia Berian, MD, MS ACS Clinical Research Scholar American College of Surgeons Chicago, IL 60611 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The US population is rapidly aging and older adults consume a disproportionate share of operations. Older adults experience a high rate of postoperative complications, which can affect quality of life. In this study, function, mobility and living situation are considered together as independent living. The study examined a large surgical database for the occurrence of loss of independence (defined as a decline in function or mobility, or increased care needs in one's living situation) and its relationship to traditional outcomes such as readmission and death after the time of discharge. Patients included in the study were age 65 or older and underwent an inpatient surgical operation. Loss of independence was assessed at the time of discharge. Readmission and death-after-discharge were assessed up to 30 days postoperatively. (more…)
Author Interviews, Cancer Research, Cost of Health Care, Health Care Systems, JAMA / 11.07.2016

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).

Alzheimer's - Dementia, Author Interviews, Brain Injury, JAMA, Parkinson's / 11.07.2016

MedicalResearch.com Interview with: Paul K. Crane, MD MPH Professor Department of Medicine Adjunct Professor Department of Health Services University of Washington MedicalResearch.com: What is the background for this study? Response: The background is that the most common experience of head injury with loss of consciousness is an apparent recovery. Sometimes this is very fast, sometimes it takes somewhat longer, but typically people return to their prior baseline. Nevertheless there is concern that the head injury may have set in motion processes that would lead to late life neurodegenerative conditions. This is bad enough for someone to deal with but it's made even worse if the head injury isn't even the victim's fault. Previous research has focused especially on Alzheimer's disease. A more limited research has focused on Parkinson's disease. We used data from three prospective cohort studies that included more than 7,000 people to study the relationship between head injury with loss of consciousness and subsequent risk of Alzheimer's and Parkinson's disease. We collected head injury exposure data at study enrollment, at a time when we administered cognitive tests and knew they did not have dementia, so our exposure data are not biased. Each of these studies also performed brain autopsies on people who died, and we evaluated data from more than 1500 autopsies. (more…)
Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA / 10.07.2016

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. (more…)
