In the American Journal of Public Health, Pooja Mehta and colleagues seek to understand the effect of unintentional injuries, suicide, and homicide on pregnancy-associated death. The authors find that about half of of pregnancy-associated deaths - occurring during or within one year of pregnancy - in Philadelphia between 2010 and 2014 were due to unintentional injuries, homicide, or suicide. Of these deaths, more than 50% were directly or indirectly associated with substance use, more than 40% were associated with serious mental illness, and more than 20% were associated with...

Andrea B. Troxel, David A. Asch, Shivan J. Mehta, Laurie Norton, Devon Taylor, Tirza A. Calderon, Raymond Lim, Jingsan Zhu, Daniel M. Kolansky, Brian M. Drachman, Kevin G. Volpp

In the American Heart Journal, Andrea Troxel and colleagues, including Kevin Volpp, David Asch and Shivan Mehta, discuss the rationale and design of the HeartStrong program, a randomized controlled trial aimed at increasing medication adherence among patients with coronary artery disease. This trial features three main innovations: first, it uses behavioral economics concepts such as intermittent feedback, regret aversion and the entertainment value of a daily lottery; second, it automates procedures using new technology such as wireless pill bottles and remote feedback; and third...

The Influence of Sugar-Sweetened Beverage Warnings - A Randomized Trial of Adolescents’ Choices and Beliefs

Sep. 13, 2016

Eric VanEpps and Christina Roberto 

In the American Journal of Preventive Medicine, Eric VanEpps and Christina Roberto measure the extent to which health-related warning labels on sugar-sweetened beverages influence adolescents’ perceptions of different beverages and their choice of beverages. The authors conducted and analyzed an online survey of 2202 demographically diverse adolescents, aged 12-18. Participants were asked to choose a beverage in a hypothetical vending machine task, rate perceptions of different beverages and indicate their interest in coupons for beverages. The participants were randomly assigned...

Acute Health Care Utilization among Food-Insecure Children in Primary Care Practices

Sep. 13, 2016

Deepak Palakshappa, Saba Khan, Chris Feudtner, and Alexander G. Fiks

In the Journal of Health Care for the Poor and Underserved, Deepak Palakshappa and colleagues, including Chris Feudtner and Alexander Fiks, investigate the relationship between food insecurity and child health care utilization. They test whether differences in child health care utilization can predict household food insecurity and whether food insecurity is associated with subsequent acute health care use. This prospective cohort study involved 3,335 children screened for food insecurity at three-year well-child visits in three urban practices. The authors evaluated acute care use...

Using Video from Mobile Phones to Improve Pediatric Phone Triage in an Underserved Population

Aug. 19, 2016

Brandi Freeman, Stephanie Mayne, A. Russell Localio, Anthony Luberti, Joseph J. Zorc, and Alexander G. Fiks

In Telemedicine and Health, Brandi Freeman and colleagues, including LDI Senior Fellow Alexander Fiks, assess the feasibility, acceptability, and utility of videos sent via mobile phones to enhance pediatric telephone triage for an underserved population with asthma. Asthma is a leading cause of childhood hospitalization, disability and healthcare-related cost. Asthma disproportionately affects Black and Hispanic children, and these populations have been shown to be more likely to use the emergency department as a routine source of sick care. Moreover, telephone triage systems...

In the Journal of Medical Internet Research, LDI Senior Fellows Alexander Fiks and Kathleen Noonan and colleagues evaluate the feasibility of using a patient portal for pediatric asthma in primary care, its impact on management and the barriers and facilitators of implementation success. Patient portals improve communication between families of children with asthma and their primary care providers as well as outcomes. This mixed-methods multi-site (11 states) study used 10 clinician focus groups, 22 semi-structured parent interviews and surveys that were sent to the parents...

The Effect of a Sunday Liquor-Sales Ban Repeal on Crime: A Triple-Difference Analysis

Jun. 21, 2016

SeungHoon Han, Charles BranasJohn MacDonald

In Alcoholism: Clinical and Experimental Research, SeungHoon Han, Charles Branas and John MacDonald investigate whether alcohol availability in state-run liquor stores affects a neighborhood’s crime rates, and if the relationship between alcohol availability and crime differs based on a neighborhood’s socioeconomic status (SES).  In 2003, Pennsylvania repealed the Sunday alcohol-sales ban for a portion of its state-run stores. The authors utilized this policy change for their analysis. They find that the repeal was associated with a significant increase in total and property-crime...
