Survival Rates In Trauma Patients Following Health Care Reform In Massachusetts, Turner Osler, Laurent G. Glance, Wenjun Li, Jeffery S. Buzas, David W. Hosmer

Wenjun Li

IMPORTANCE: Massachusetts introduced health care reform (HCR) in 2006, expecting to expand health insurance coverage and improve outcomes. Because traumatic injury is a common acute condition with important health, disability, and economic consequences, examination of the effect of HCR on patients hospitalized following injury may help inform the national HCR debate. OBJECTIVE: To examine the effect of Massachusetts HCR on survival rates of injured patients. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 1,520,599 patients hospitalized following traumatic injury in Massachusetts or New York during the 10 years (2002-2011) surrounding Massachusetts HCR using data from the State Inpatient ...

Robert J. Goldberg

There are limited population-based data available describing trends in the long-term prognosis of patients discharged from the hospital after an initial acute myocardial infarction (AMI). Our objectives were to describe multidecade trends in post-discharge mortality and their association with hospital management practices in patients discharged from all medical centers in Central Massachusetts after a first AMI. Residents of the Worcester, Massachusetts, metropolitan area discharged from all hospitals in Central Massachusetts after a first AMI from 1975 to 2009 comprised the study population (n = 8,728). Multivariable-adjusted logistic regression analyses were used to examine the association between year of hospitalization and ...

Predictive Value Of The Functional Movement Screen As It Relates To Anterior Cruciate Ligament Injury, Daniel A. Herring, Kyle D. Cherry, Hannah L. Stedge

Hannah L. Stedge, M.S.

Introduction: Anterior cruciate ligament injuries occur over 200,000 times annually in the United States alone (Brophy, et al. 2009). This injury strains the healthcare system and affects the players, teams, parents, and the organization they are a part of. There have been, however, clinically researched risk factors that predispose athletes to ACL injury (Gignac, et al. 2015; Laible, et al. 2014). As a result, there is a clinical need for an effective screening tool to identify those athletes at risk for ACL injury. The Functional Movement Screen has been shown to be an effective screening tool for detecting athletes ...

"What's App?" Utilizing Evidence Based Medicine Apps In The Clinical Setting, Kathryn C. O'Donovan

BU Well

The medical community has utilized evidence-based medicine, or EBM, in practice for decades, and healthcare personnel are used to the idea of utilizing research and statistics to determine the treatment of patients. However, as technology advances, the use of electronics and EBM apps has increased in the clinical setting. While there are advantages to clinicians having resources at their fingertips as they talk with patients, there are also hurdles that could harm or offend patients. So as healthcare inevitably becomes more and more electronic, can providers strike the balance needed to effectively use EBM apps in practice to provide optimum ...

Geodemographic Features Of Human Blastomycosis In Eastern Wisconsin, Megan E. Huber, Dennis J. Baumgardner, Jessica J. F. Kram, Melissa A. Lemke

Dennis J. Baumgardner. MD

Purpose

Blastomycosis is an endemic fungal infection. In rural northern Wisconsin, blastomycosis cases are associated with certain environmental features including close proximity to waterways. Other studies have associated blastomycosis with particular soil chemicals. However, blastomycosis also occurs in urban and suburban regions. We explored the geodemographic associations of blastomycosis cases in the more urban/suburban landscape of eastern Wisconsin.

Methods

We conducted a retrospective study of 193 laboratory-identified blastomycosis cases in a single eastern Wisconsin health system, 2007–2015. Controls were 250 randomly selected cases of community-diagnosed pneumonia from a similar time period. Geographic features of home addresses were explored ...


Association Between First Trimester Pregnancy Associated Plasma Protein–A (Papp-A) And Gestational Diabetes Mellitus Development, Aylin Sert, Katherine Leung, Molly E. Waring, Raziel Rojas-Rodriguez, Silvia Corvera, Tiffany A. Moore Simas 2016 University of Massachusetts Medical School

Association Between First Trimester Pregnancy Associated Plasma Protein–A (Papp-A) And Gestational Diabetes Mellitus Development, Aylin Sert, Katherine Leung, Molly E. Waring, Raziel Rojas-Rodriguez, Silvia Corvera, Tiffany A. Moore Simas

Senior Scholars Program

Background: Gestational diabetes (GDM) is a common pregnancy complication with significant cardiometabolic consequences for mothers and offspring. Previous research from our group suggests that adipose tissue IGFBP-5 and its unique metalloprotease PAPP-A (Pregnancy Associated Plasma Protein-A) may play mechanistic roles in GDM development by regulating functional IGF-1 levels and lipid storage and metabolism.

Aim: To examine the relationship between circulating PAPP-A levels and GDM development. We hypothesized that high first trimester PAPP-A levels would be associated with decreased GDM risk.

Methods: A retrospective cohort of women delivering singleton gestations at UMass Memorial Healthcare (2009, 2010, 2014 ...

The Role Of Mathematical Modeling In Designing And Evaluating Antimicrobial Stewardship Programs, Lester Caudill, Joanna R. Wares 2016 University of Richmond

The Role Of Mathematical Modeling In Designing And Evaluating Antimicrobial Stewardship Programs, Lester Caudill, Joanna R. Wares

Math and Computer Science Faculty Publications

Antimicrobial agent effectiveness continues to be threatened by the rise and spread of pathogen strains that exhibit drug resistance. This challenge is most acute in healthcare facilities where the well-established connection between resistance and sub-optimal antimicrobial use has prompted the creation of antimicrobial stewardship programs (ASPs). Mathematical models offer tremendous potential for serving as an alternative to controlled human experimentation for assessing the effectiveness of ASPs. Models can simulate controlled randomized experiments between groups of virtual patients, some treated with the ASP measure under investigation, and some without. By removing the limitations inherent in human experimentation, including health risks, study ...

Reliability Of Predicting Early Hospital Readmission After Discharge For An Acute Coronary Syndrome Using Claims-Based Data, David McManus, Jane Saczynski, Darleen Lessard, Molly Waring, Jeroan Allison, David Parish, Robert Goldberg, Arlene Ash, Catarina Kiefe 2016 University of Massachusetts Medical School

Reliability Of Predicting Early Hospital Readmission After Discharge For An Acute Coronary Syndrome Using Claims-Based Data, David Mcmanus, Jane Saczynski, Darleen Lessard, Molly Waring, Jeroan Allison, David Parish, Robert Goldberg, Arlene Ash, Catarina Kiefe

Jeroan J. Allison

Early rehospitalization after discharge for an acute coronary syndrome, including acute myocardial infarction (AMI), is generally considered undesirable. The Centers for Medicare and Medicaid Services (CMS) base hospital financial incentives on risk-adjusted readmission rates after AMI, using claims data in its adjustment models. Little is known about the contribution to readmission risk of factors not captured by claims. For 804 consecutive patients > 65 years discharged in 2011 to 2013 from 6 hospitals in Massachusetts and Georgia after an acute coronary syndrome, we compared a CMS-like readmission prediction model with an enhanced model incorporating additional clinical, psychosocial, and sociodemographic characteristics, after ...
