Abbott, Author Interviews, Flu - Influenza / 08.10.2018

MedicalResearch.com Interview with: Dr. Norman Moore PhD Abbott’s Director of Scientific Affairs for Infectious Diseases  MedicalResearch.com: What is the background for this test? How does ID NOW differ from other tests for influenza? Response: This test was developed to give providers – and their patients – lab-accurate results more quickly than ever, right at the point of care. It was designed for ease of use, as well as to be portable and small enough that it can be used in a broad range of healthcare settings, including walk-in clinics, urgent care centers, doctors’ offices and emergency rooms. Prior to ID NOW, traditional molecular tests offered great performance, but took too long to impact treatment decisions. ID NOW is able to deliver the performance and accuracy of lab-based tests in a timeframe that offers the best chance of improving treatment decisions.  (more…)

MedicalResearch.com Interview with: Vinay Kini, MD, MS Division of Cardiovascular Medicine Hospital of the University of Pennsylvania The Leonard Davis Institute of Health Economics University of Pennsylvania Philadelphia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent studies have shown that use of cardiac stress tests has declined by about 25% among Medicare beneficiaries and by about 50% in Kaiser Permanente over the last several years. However, the reasons for these declines is not well understood. Decreases in the use of stress testing could be due to dissemination of appropriate use criteria and other clinical practice guidelines, advances in preventive care, reductions in reimbursement for testing, or other health system organizational characteristics. Therefore, our goal was to determine whether similar declines in testing are observed among a nationally representative cohort of commercially insured patients. We identified over 2 million stress tests performed among 33 million members of the commercial insurance company, and found that there was a 3% increase in the overall use of stress testing in this cohort between 2005 and 2012. Declines in the use of nuclear SPECT tests were offset by increases in the use of stress echocardiography, exercise electrocardiography, and newer stress test modalities such as coronary computed tomography angiography. The largest increase in use of testing was seen among younger individuals - there was a 60% increase in use of testing among patients aged 25-34, and a 30% increase among individuals aged 35-44.

Author Interviews, Brigham & Women's - Harvard, JAMA, Kidney Disease / 03.03.2015

Mallika L. Mendu, MD, MBA Division of Renal Medicine Brigham and Women’s Hospital, Harvard Medical School Boston, MAMedicalResearch.com Interview with: Mallika L. Mendu, MD, MBA Division of Renal Medicine Brigham and Women’s Hospital, Harvard Medical School Boston, MA MedicalResearch: What is the background for this study? What are the main findings? Dr. Mendu: Chronic kidney disease affects a significant number of adults in the United States, approximately 13%, and is associated with significant morbidity, mortality and cost. We conducted a review of 1487 patients referred for initial evaluation of chronic kidney disease to two academic medical centers in Boston over a 3-year period, and examined how often laboratory and imaging tests were ordered and how often these tests affected diagnosis and/or management. The main finding was that a number of tests (renal ultrasound, paraprotein testing, serologic testing) were commonly ordered despite low diagnostic and management yield. Urine quantification and hemoglobin A1c testing had the highest diagnostic and management yield. (more…)
Author Interviews, Baylor College of Medicine Houston, Cost of Health Care, Heart Disease, JAMA / 03.07.2013

 MedicalResearch.com Interview with Salim S. Virani, MD, PhD Health Policy and Quality Program, Michael E. DeBakey Veterans Affairs Medical Center Health Services Research and Development Center of Excellence, and Section of Health Services Research, Department of Medicine, Baylor College of Medicine, Section of Cardiovascular Research, Department of Medicine, Baylor College of Medicine, and Center for Cardiovascular Disease Prevention, Methodist DeBakey Heart and Vascular Center, Houston, Texas MedicalResearch.com: What are the main findings of the study? Dr. Virani: The main findings of the study are that despite having cholesterol levels at goal (LDL cholesterol <100 mg/dL), about one-third of patients (9200 out of 27947) with coronary heart disease had repeat cholesterol testing in 11 months from their last lipid panel. As expected, no intervention was performed as a response to these lipid panels. Collectively, 12686 additional lipid panels were performed in these patients.  Among 13,114 patients who met the optional treatment target of LDL-C<70 mg/dL, repeat lipid testing was performed in 8,177 (62.3% of those with LDL-C<70) during 11 months of follow-up. Patients with a history of diabetes mellitus (odds ratio [OR], 1.16; 95% CI, 1.10-1.22), a history of hypertension (OR, 1.21; 95%CI, 1.13-1.30), higher illness burden (OR, 1.39; 95%CI, 1.23-1.57), and more frequent primary care visits (OR, 1.32; 95%CI, 1.25-1.39) were more likely to undergo repeat testing, whereas patients receiving care at a teaching facility (OR, 0.74; 95%CI, 0.69-0.80) or from a physician provider (OR, 0.93; 95%CI, 0.88-0.98) and those with a medication possession ratio of 0.8 or higher (OR, 0.75; 95%CI, 0.71-0.80) were less likely to undergo repeat testing.
