Low Health Literacy Is Associated With Frailty And Reduced Likelihood Of Liver Transplant Listing: A Prospective Cohort Study

Jun. 21, 2020

Therese Bittermann, Kristen Dwinnells, Sakshum Chadha, Michael S. Wolf, Kim M. Olthoff, Marina Serper

Abstract [from journal]

The effect of low health literacy (HL) on outcomes in end-stage liver disease (ESLD) is largely unknown. The association of low HL on clinical outcomes was investigated in a prospective cohort of outpatients with ESLD undergoing liver transplant (LT) evaluation. From 2014-2017, 276 patients underwent LT evaluation with assessments of liver disease severity, medical and psychosocial comorbidities, physical frailty, and malnutrition. Literacy was measured with the Newest Vital Sign (NVS), a brief validated assessment. Multivariable

Association Among Surgeon Experience, Patient Risk, And Outcomes In Coronary Artery Bypass Grafting

Jun. 13, 2020

Jason J. Han, Markian M. Bojko, Matthew M. Duda, Amit Iyengar, John J. Kelly, William L. Patrick, Mark R. Helmers, Pavan Atluri

Abstract [from journal]

Background: There is an association between surgeon experience and outcomes following cardiac surgery. However, this association is not well studied in the context of patient risk. The purpose of this single-center, retrospective, observational study was to describe how surgeon experience relates to patient risk in isolated coronary artery bypass graft (CABG) surgery and how this impacts patient outcomes.

Methods: Surgeon experience was defined as time between the surgeon finishing fellowship

Preferences For Predictive Model Characteristics Among People Living With Chronic Lung Disease: A Discrete Choice Experiment

Jun. 12, 2020

Gary E. Weissman, Kuldeep N. Yadav, Trishya Srinivasan, Stephanie Szymanski, Florylene Capulong, Vanessa Madden, Katherine R. Courtright, Joanna L. Hart, David A. Asch, Sarah J. Ratcliffe, Marilyn M....

Abstract [from journal]

Background. Patients may find clinical prediction models more useful if those models accounted for preferences for false-positive and false-negative predictive errors and for other model characteristics. Methods. We conducted a discrete choice experiment to compare preferences for characteristics of a hypothetical mortality prediction model among community-dwelling patients with chronic lung disease recruited from 3 clinics in Philadelphia. This design was chosen to allow us to quantify "exchange

Association Of A Novel Index Of Hospital Capacity Strain With Admission To Intensive Care Units

Jun. 10, 2020

George L. Anesi, Marzana Chowdhury, Dylan S Small, M. Kit Delgado, Rachel Kohn, Brian Bayes, Wei Wang, Erich Dress, Gabriel J. Escobar, Scott D. Halpern, Vincent X Liu

Abstract [from journal]

Rationale: Prior approaches to measuring healthcare capacity strain have been constrained by using individual care units, limited metrics of strain, or general, rather than disease-specific, populations.

Objectives: We sought to develop a novel composite strain index and measure its association with ICU admission decisions and hospital outcomes.

Methods: Using more than 9.2 million acute care encounters from 27 Kaiser Permanente Northern California and Penn Medicine

Pathways To Help-Seeking Among Black Male Trauma Survivors: A Fuzzy Set Qualitative Comparative Analysis

Jun. 9, 2020

John A. Rich, Theodore J. Corbin, Sara F. Jacoby, Jessica L. Webster, Therese S. Richmond

Abstract [from journal]

Many Black men suffer symptoms of traumatic stress in the aftermath of traumatic injury, and they also often carry social concerns, including experiences of discrimination and stigma, and a lack of financial resources. The objective of the present study was to understand how traumatic symptoms and social factors combine in complex ways toward the outcome of psychological help-seeking. We analyzed qualitative and quantitative data from 32 injured Black men admitted to a Level 1 trauma center. Qualitative interviews explored their

Suprapubic Versus Urethral Catheter For Urinary Drainage After Robot-Assisted Radical Prostatectomy

Leilei Xia
Jun. 6, 2020

Leilei Xia, Thomas J Guzzo, Phillip Mucksavage, Daniel J. Lee 

Abstract [from journal]

Purpose of review: To review the evidence regarding the usage of suprapubic tube (SPT) versus indwelling urethral catheter (IUC) after robot-assisted radical prostatectomy (RARP).

Recent findings: Available data on the use of SPT for urinary drainage after RARP is somewhat limited mostly because of the variations of study designs and non-standardized outcomes. Although it may provide some mild benefit in terms of catheter-related pain and discomfort, the benefit seems not to be clinically

Determinants Of Stigma Among Patients With Hepatitis C Virus (HCV) Infection

Jun. 5, 2020

M. Elle Saine, Julia E. Szymczak, Tyler M. Moore, Laura P. Bamford, Frances K. Barg, Jason SchnittkerJohn H. HolmesNandita Mitra, Vincent Lo Re

Abstract [from journal]

Stigma around hepatitis C virus (HCV) infection is an important and understudied barrier to HCV treatment and elimination. The determinants of HCV-related stigma, including the impacts of stage of HCV treatment (i.e., spontaneously-cleared; diagnosed, untreated; previously treated, not cured; currently being treated; treated, cured) and coinfection with human immunodeficiency virus (HIV), remain unknown. To address these gaps, we conducted a cross-sectional study among patients with a history of HCV infection (n=270) at outpatient

Abstract [from journal]

Background: Assessing the postoperative recovery of pediatric patients is challenging as there is no validated comprehensive patient-centered recovery assessment tool for this population. A qualitative investigative approach with in-depth stakeholder interviews can provide insight into the recovery process and inform the development of a comprehensive patient-centered postoperative assessment tool for children.

Methods: We conducted open-ended, semistructured interviews with children 6-12 years

Elinore Kaufman, U of Penn
Jun. 1, 2020

Elinore J. Kaufman, Christopher N. Morrison, Erik J. Olson, David K. Humphreys, Douglas J. Wiebe, Niels D. Martin, Carrie A. Sims, Mark H. Hoofnagle, C. William Schwab, Patrick M. Reilly, Mark J. Seamon

Abstract [from journal]

Background: Federal law requires background checks for firearms purchased from licensed dealers, but states can extend requirements to private sales of handguns and purchases at gun shows (universal background checks for handguns [UBC-HG]). Although firearm homicide disproportionately affects African Americans, little is known about how UBG-HG impacts African Americans. We hypothesized that implementation of UBC-HG would reduce rates of firearm homicide of African Americans.

Methods: We
