Contextualizing prescription opioid misuse and heroin use within dimensional models of drug involvement.

ABSTRACT:

Background

Prescription opioid misuse (POM) is often implicated in heroin initiation, despite evidence that POM does not predict heroin initiation any better than other drug use. Additionally, prescription misuse and illicit use behaviors tend to respectively "cluster" together. This study aimed to test a series of theory-driven factor models to explore how POM and heroin use are situated within the broader constellation of drug use that typically occurs alongside opioid (mis)use.

Methods

36,309 individuals from NESARC-III (56.31% female; mean age=45.63 [SD=17.53]) reported their lifetime (mis)use of prescription opioids, prescription stimulants, prescription sedatives, heroin, cannabis, cocaine/crack, illicit stimulants (e.g., methamphetamine), club drugs, hallucinogens, and inhalants, and were administered a DSM-5 substance use disorder (SUD) assessment. Bifactor, correlated factors, and one-factor confirmatory factor models were fit using all drug use/SUD variables and subsequently compared.

Results

POM was most strongly correlated with prescription sedative misuse; heroin use was most strongly correlated with cocaine/crack use. All factor models fit the data well. Highly correlated factors and patterns of factor loadings suggested that POM and heroin use were most parsimoniously captured within a general factor alongside all other forms of drug use. This was also the case for SUD. Additional analyses testing an alternate factor structure provided further support for unidimensionality.

Conclusions

POM and heroin use, as well as prescription- and heroin-based SUDs, were neither separable nor distinctly associated. Future research should account for other drug use more comprehensively rather than isolating POM as a primary risk factor in heroin use and use disorder.

Project description:BackgroundAdolescent misuse of prescription opioids is hazardous. This study aimed to generate data on prescription opioid misuse trajectories across adolescence and identify risk factors and mechanisms for more dangerous use trajectories.MethodsUsing a prospective longitudinal cohort repeated measures design, baseline (Fall 2013) and seven semiannual assessments were administered through Spring 2017 in 10 public high schools in Los Angeles, CA. Frequency of past 30-day prescription opioid misuse was captured. Trajectory groups were identified using growth mixture modeling and multinomial logistic regression identified associations between baseline risk factors with membership in each trajectory group.ResultsOverall, 3395 students were evaluated (53.4% female, Mean [SD] age at baseline=14.58[0.40]; range=12.83-16.29). Four discrete misuse trajectories were identified among 1062 students: (1) Minimal/Experimental (infrequent time-limited use; range of estimated mean number of days using prescription opioid across waves=0.0-0.6 days]; N = 705[20.8%]); (2) Low Deescalating (range=2.0-0.7 days; N = 189[5.6%]); (3) Moderate Escalating (range=0.7-3.6 days; N = 108[3.2%]); and (4) Frequent Persistent (range=4.7-9.4 days; N = 60[1.8%]). Students reporting tobacco, cannabis, alcohol use, or impulsivity in 9th grade were more likely to demonstrate membership in the Moderate Escalating trajectory class when compared to 2333 (68.7%) students reporting sustained abstinence. Female sex, peer opioid misuse, alcohol use, other substance use, impulsivity, or delinquent behavior reported in 9th grade was associated with membership in the Frequent Persistent trajectory class.ConclusionsPrescription opioid misuse in adolescence appears to follow 4 discrete trajectories, including the potentially problematic Moderate Escalating and Frequent Persistent trajectories. Female sex, peer influences, substance use, and intrapersonal risk factors were associated with membership in these classes.

Project description:BackgroundVaginal delivery is the most common reason for hospitalization in the United States, and approximately 30% of women fill an opioid prescription after vaginal delivery, making this a common source of opioid exposure in women of reproductive age.ObjectiveThis study aimed to evaluate the effect of receiving an opioid prescription after vaginal delivery on the risk of subsequent persistent opioid use, opioid use disorders, and overdose.Study designWe assembled a nationwide cohort of Medicaid beneficiaries in the United States using the Medicaid Analytic eXtract 2009-2014. The study population included pregnant women who delivered vaginally between 2009 and 2013 and were continuously enrolled in Medicaid from 90 days before to 365 days after delivery. We identified patients with prescription opioids dispensed within 7 days of the date of vaginal delivery. Persistent opioid use was defined as ≥10 opioid fills or >120 days' supply dispensed from 30 to 365 days after delivery. Incident diagnoses of opioid use disorder and overdose were ascertained during the same interval. Propensity score matching was used to control for potential confounding factors.ResultsAmong 459,829 pregnancies ending in vaginal deliveries, 140,807 (30.62%) had an opioid dispensed within 7 days of delivery. Overall, 5770 of 140,807 (4.10%) women who filled an opioid prescription vs 2668 of 319,022 (0.84%) unexposed women had subsequent persistent opioid use, with an unadjusted relative risk of 4.90 (95% confidence interval, 4.68-5.13) and a risk difference of 3.26% (95% confidence interval, 3.15-3.37). After propensity score matching, the risk remained higher among pregnancies with an opioid prescription dispensed, with a relative risk of 2.57 (95% confidence interval, 2.43-2.72) and a risk difference of 2.21% (95% confidence interval, 2.08-2.33), which was confirmed by the instrumental variable analysis with a risk difference of 1.31% (95% confidence interval, 1.06-1.56) by using the rate of opioid prescribing at the delivery facility in a given geographic region as the instrument. The adjusted relative risk of newly diagnosed opioid use disorder and overdose was 1.48 (95% confidence interval, 1.40-1.57) and 1.92 (95% confidence interval, 1.20-3.09), respectively.ConclusionOpioid dispensing following vaginal delivery is associated with future persistent opioid use and misuse, independent of confounding factors. Opioid prescriptions to women after vaginal delivery should be avoided, except in rare circumstances.
