Examining the opioid epidemic through the lens of crime data

UNIVERSITY PARK, Pa. - The opioid overdose epidemic in the United States remains a critically important public health issue that continues to worsen as time goes on. The estimated death toll in 2021 has reached the historical high of 100,000 overdose deaths from all drugs and over 75,000 deaths from opioid overdoses. We hear a lot about healthcare data used to indicate the state of the crisis, but what about using crime data as another tool?
A new study published this month by Penn State researchers using crime incident data found that opioid-related crime incident rates were positively associated with rates of opioid-related emergency department visits, hospitalizations, and overdose mortality.
Qiushi Chen, assistant professor of industrial and manufacturing engineering, and the lead investigator on the project, noted that while healthcare data and outcomes are commonly used to characterize the state of the epidemic and evaluate the impact of policy changes, criminal justice data is under-utilized in research despite its high relevance and unique role in the opioid crisis.
“We used incident-level crime data from the National Incident-Based Reporting System (NBIRS) to identify all incidents involving opioids and examined whether using crime data could describe temporal trends and shifting patterns in the opioid epidemic. Our results were highly consistent with health-related data, making crime data a potential powerful tool for understanding the changing landscape of the crisis,” Chen said.
Using crime data
The team’s results were consistent with the evolving nature of the opioid epidemic as seen by the distinct waves of opioid overdose deaths. Historically, the opioid epidemic has occurred within the United States in four distinct waves. The first wave (1999-2010) was largely attributed to prescription opioid painkillers; the second wave (2010-13) was associated with a shift towards heroin use; the third wave (2013-late 2010s) has seen a concerning shift towards potent synthetic opioids like fentanyl; and the fourth and current wave involves a shift towards poly-substance use and a surge in stimulant-involved (cocaine and methamphetamine) in fatal overdoses, exceeding those from prescription opioids.
“And we found that the increase of opioid-related crime incident rates was predominantly characterized by incidents involving prescription opioids before 2020, followed by an accelerated shift to heroin-related incidents after 2010,” said Glenn Sterner, assistant professor of criminal justice at Penn State Abington and Consortium on Substance Use and Addiction co-funded faculty member.
Impact on the healthcare system
Tracking the opioid epidemic through crime data showed a significant relationship between opioid-related crimes and opioid-related emergency department and inpatient visits. According to Joel Segel, associate professor of health policy and administration and another investigator on the research team, opioid possession crimes may be more associated with adverse opioid-related health outcomes than opioid distribution crimes because they may better capture instances of substance use by individuals.
The study found that opioid-related overdoses were more highly predictive of opioid-related hospitalization, and that opioid-related hospitalizations were more predictive of fatal opioid overdoses.
“This is not surprising," Segel said, “because non-fatal overdoses often occur prior to fatal overdoses." The team’s results indicate that criminal justice data may strongly predict future healthcare utilization and overdose deaths. For example, if an individual misuses opioids or other substances, that individual may be more likely to interact with the criminal justice system earlier than the healthcare system, or before a fatal overdose can occur.
In addition to that, the team acknowledged that interventions for those who are justice-involved may help reduce burdens on the healthcare system in the future, and more attention paid to those who utilize healthcare services to reduce acute substance use-related issues.
Opportunities for policy changes
“One of the most critical steps that we can take in regard to developing policies around substance use and misuse, overdose prevention and harm reduction is collecting and synthesizing different types of data for policymakers,” Chen said. “Unfortunately, coordinating efforts across different entities to ensure data sharing is often a slow, technically complex process.”
Reducing barriers for data sharing, locally and nationally, would help to comprehensively address the opioid epidemic and other emerging substance use issues, according to the researchers. Not all states or local communities have developed infrastructure with adequate capacity and resources to collect, compile and match cross-sector data sets. Applying analytics to relevant data from public domain, such as the NIBRS data with detailed information at incident level, could be among practical alternative approaches for identifying emerging trends of substance uses in the community.
However, Chen emphasized the importance of a multi-pronged infrastructure with adequate policy and bureaucratic support. “In order to address the opioid crisis as a multi-faceted problem, a systematic approach is necessary to unify efforts across different sectors of healthcare, public health, and criminal justice," said Chen.
The project also included Zixuan Feng, a doctoral student in industrial and manufacturing engineering. This research was funded by Penn State’s Social Science Research Institute seed grant and supported by the Social Science Research Institute’s Consortium on Substance Use and Addiction at Penn State.
