The National Center for Biotechnology Information

Tze Chiam, Keshab Subedi, David Chen, Eric Best, Federica B. Bianco, Gregory Dobler, and Mia Papas


Background and Aim: This study aims to determine COVID-19 patient demographics and comorbidities associated with their hospital length of stay (LOS). Methods: Design: Single-site, retrospective study. Setting: A suburban 700-bed community hospital in Newark, Delaware, USA. Patients: Patients admitted to the hospital from March 11, 2020, to August 11, 2020, with a positive COVID-19 status. We followed a time-to-event analysis approach and used Kaplan–Meir curves and log-rank tests for bivariate analyses, and an accelerated failure time model for a multivariable model of hospital LOS.

Abstract Objective Healthcare systems globally were shocked by coronavirus disease 2019 (COVID-19). Policies put in place to curb the tide of the pandemic resulted in a decrease of patient volumes throughout the ambulatory system. The future implications of COVID-19 in healthcare are still unknown, specically the continued impact on the ambulatory landscape.

Validation of a 2-Item Food Insecurity Screen Among Adult General Medicine Outpatients


Cecelia Harrison, Jennifer N Goldstein, Adebayo Gbadebo, Mia Papas


Abstract Food insecurity is defined as limited access to food and is associated with adverse physical, social, and emotional health outcomes. As social needs are addressed in heath care, efficient methods to identify patients living in food insecure households are necessary. A 2-item screen (HFSS-2) derived from the US Department of Agriculture Household Food Security Scale (HFSS-18) has been validated among parents of pediatric patients with a sensitivity of 97% and specificity of 83%.

Does Preparedness Matter? The Influence of Household Preparedness on Disaster Outcomes During Superstorm Sandy


Lauren A Clay, James B Goetschius, Mia A Papas, Joseph Trainor, Nuno Martins, James M Kendra


Abstract Objectives: This study empirically examines preparedness with a kit, medication, and a disaster plan on disaster outcomes including perceived recovery, property damage, and use of medical or mental health services. Methods: Using a cross-sectional, retrospective study design, 1114 households in New York City were interviewed 21-34 months following Super Storm Sandy. Bivariate associations were examined and logistic regression models fit to predict the odds of disaster outcomes given the level of preparedness.
