Rose Kagawa, PhD, MPH: Mexico’s Conditional Cash Transfer Program and Interpersonal Violence
We estimated the effect of Mexico’s conditional cash transfer program on the incidence of poor health resulting from violent victimization. In preliminary analyses, the number of years a community was enrolled in the program was correlated with a lower risk of poor health resulting from violence, but the associations were attenuated and no longer statistically significant after adjustment for community level factors such as poverty.
Nicole Kravitz-Wirtz, PhD, MPH: Effects of Good Samaritan Laws on Prescription Opioid and Heroin Overdose Fatalities
Opioid overdose deaths are largely preventable via timely access to emergency care. However, many people delay or do not call 911 due to fears of police involvement and criminal sanctions. To address this concern, most states passed Good Samaritan laws (GSLs), which provide limited criminal immunity to individuals acting in good faith who summon emergency services in the event of a drug overdose. This study used county-level mortality data and a spatiotemporal approach to examine the immediate and three-year-lagged effects of GSLs on fatal overdoses involving prescription opioids, heroin, and synthetic opioids in 3,109 counties in 49 states for the period 2002 to 2016.
Veronica Pear, MPH: Drugs and Despair: An Analysis of Community-Level Opioid-Related Harm and Suicide
The aim of this study was to evaluate whether increases in community-level opioid-related hospitalizations and deaths were associated with increases in community-level suicide (overall and by method). To study this association, we used monthly county hospitalization and mortality data for 15 states from 2001 to 2014. We found that spikes in opioid-related harm were associated with a modest but significant increase in suicides overall, in poisoning suicides, and in other (non-firearm, non-poisoning) suicides 12 months after a spike occurred; there was, additionally, a small increase in firearm suicides 2 months following a spike in opioid-related harm.
Veronica Pear, MPH: Risk Factors for Morbidity and Mortality Following a Firearm Assault Injury: A Population-Based Retrospective Cohort Study
** 1st Prize Winner, Poster Session 3
This study used all hospital inpatient, emergency department, and mortality data in California from 2005-2013 to characterize the hazards of and risks for recurrent firearm assaults or homicide among people with an initial firearm assault injury. We also looked into how these hazards and risk factors changed with each additional firearm assault injury. We found that each firearm assault injury increased the victim’s probability of experiencing a subsequent fatal or nonfatal firearm assault. Male sex and black race were associated with an increased hazard of reinjury or death from a firearm assault; older age was associated with a decreased hazard.
