Risk Communication

The exchange of information about the probability and consequences of adverse events, and how these risks are perceived and managed.

HIV and Suicide Risk

Sep. 14, 2020

In recent years, remarkable achievements in HIV testing and antiretroviral therapies have improved the detection, management, and care of persons living with HIV (PLWH). In the 1980s and 90s, patients with HIV infection faced a devastating prognosis. But now, with proper medications and support, PLWH can enjoy long and fulfilling lives. Thus, when the topic of suicide among PLWH is raised, many physicians are surprised. They often ask me, “wasn’t suicide an issue of a time before we had access to antiretroviral therapies?”

Abstract [from journal]

As COVID-19 is rapidly unfolding in the United States, it is important to understand how individuals perceive the health and economic risks of the pandemic. In the absence of a readily available medical treatment, any strategy to contain the virus in the US will depend on the behavioral response of US residents. In this paper, we study individual's perceptions on COVID-19 and social distancing during the week of March 10-16, 2020, a week when COVID-19 was officially declared to be a pandemic by WHO and when new infections in the US

Abstract [from journal]

Objectives: Central-line associated bloodstream infection (CLABSI) is associated with increased mortality, morbidity, and cost in hospitalized children. An evidence-based bundle of care can decrease CLABSI, but bundle compliance is imperfect. We explored factors impacting bundle performance in the pediatric intensive care unit (PICU) by bedside nurses.

Methods: Single-center cross sectional electronic survey of PICU bedside nurses in an academic tertiary care center; using the COM-B (

Abstract [from journal]

Persons living with HIV (PLWH) are significantly more likely to die by suicide compared to the general population. This is the first study to examine the impact of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), insomnia, and substance use disorders on suicidal ideation/behavior among PLWH using electronic medical record (EMR) data. We also evaluated the mutual influence of interactions between PTSD and substance use disorders on suicide risk, consistent with the substance abuse, violence exposure, and HIV/AIDS

The objective of this study was to explore the association between mothers' postoperative opioid prescriptions and incidence of opioid-related events in their children (aged 1 to 24 years).

Data and methods: This retrospective cohort study used individually linked administrative health data from Ontario, Canada. A population-based sample of 170,

Abstract [from journal]

Background: Few interventions have targeted low-income adults with moderate-severe asthma despite their high mortality.

Objective: To assess whether a Patient Advocate intervention improves asthma outcomes over usual care.

Methods: This 2-armed randomized clinical trial recruited adults with moderate-severe asthma from primary care and asthma specialty practices serving low-income neighborhoods. Patients were randomized to 6 months of a Patient Advocate Intervention or

Abstract [from journal]

Purpose: To measure incidence rates of and risk factors for opioid overdose among new users of prescription opioids in the Medicaid population.

Methods: A cohort study using Medicaid claims from four states (1999-2012) among adults continuously enrolled in Medicaid for ≥3 years free of opioid prescriptions and opioid overdose before cohort entry. Exposure and outcome of interest were prescription opioid use and apparent incident opioid overdose identified in inpatient and outpatient claims (


As Violence Unfolds: A Space-Time Study Of Situational Triggers Of Violent Victimization Among Urban Youth

Beidi Dong, Christopher N. Morrison, Charles C. Branas, Therese S. RichmondDouglas J. Wiebe

Abstract [from journal]

Objectives: This study clarifies three important issues regarding situational or opportunity theories of victimization: 1) whether engaging in risk activities triggers violent assault during specific, often fleeting moments, 2) how environmental settings along individuals' daily paths affect their risk of violent assault, and 3) whether situational triggers have differential effects on violent assault during the day versus night.

Methods: Using an innovative GIS-assisted interview technique,

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
