Perceived social support in patients with chronic pain with and without opioid use disorder and role of medication for opioid use disorder.
A significant predictor of treatment outcomes for patients with chronic non-cancer pain (CNCP) and opioid use disorder (OUD) is the degree and quality of social support they receive. Specifically, in patients with CNCP and on long-term opioid therapy, the development of OUD tends to be associated with losses in social support, while engagement in treatment for OUD improves support networks. Delivery of the evidence-based OUD treatment medications, methadone and buprenorphine, occurs in clinical environments which patently differ with respect to social support resources. The aims of this study were to describe perceived social support in patients with CNCP without OUD (no-OUD), with OUD and on buprenorphine (OUD-BP), and with OUD and on methadone (OUD-methadone). ⋯ Patients with CNCP and OUD on methadone therapy endorse levels of social support comparable to those without OUD, however those on buprenorphine therapy report significantly less support, bringing implications for OUD treatment outcomes.

Genetic predisposition to alcohol dependence: The combined role of polygenic risk to general psychopathology and to high alcohol consumption.
High alcohol consumption and alcohol dependence are only partly genetically correlated and they differ considerably in their correlations with other traits. The existence of genetic correlation among alcohol dependence and psychiatric disorders may be attributed to the presence of a general psychopathology factor, the p factor. This study investigates the relationship of polygenic risk to general psychopathology and to high alcohol consumption on alcohol dependence. ⋯ Polygenic risk for alcohol dependence can be split at least into two components, involved in general psychopathology and high alcohol consumption. The first component of PCA based on PRS for different psychiatric disorders allows estimation of the contribution of the polygenic p factor to alcohol dependence. The pleiotropic effects of genetic variants across psychiatric disorders are mainly manifested as alcohol dependence in some patients.

Patient, prescriber, and Community factors associated with filled naloxone prescriptions among patients receiving buprenorphine 2017-18.
Prescribing naloxone to patients at increased opioid overdose risk is a key component of opioid overdose prevention efforts, but little is known about naloxone fills among patients receiving buprenorphine for opioid use disorder, one such high risk group. ⋯ Prescribing naloxone to patients receiving buprenorphine represents a tangible clinical action that can be taken to help prevent opioid overdose deaths. However, despite recommendations to co-prescribe naloxone to patients at increased risk for opioid overdose, rates of filling naloxone prescriptions remain low among patients dispensed buprenorphine. States, insurers, and health systems should consider implementing strategies to facilitate increased co-prescribing of naloxone to at-risk individuals.

"Doctor and pharmacy shopping": A fading signal for prescription opioid use monitoring?
The term "doctor and pharmacy shopping" colloquially describes patients with high multiple provider episodes (MPEs)-a threshold count of distinct prescribers and/or pharmacies involved in prescription fulfillment. Opioid-related MPEs are implicated in the global opioid crisis and heavily monitored by government databases such as U.S. state prescription drug monitoring programs (PDMPs). We applied a widely-used MPE definition to examine U.S. trends from a large, commercially-insured population from 2010 to 2017. Further, we examined the proportion of enrollees identified as "doctor shoppers" with evidence of a cancer diagnosis to examine the risk of false positives. ⋯ Opioid "shopping" flags are a long-standing but rapidly fading PDMP signal. To avoid unintended consequences, such as identifying legitimate medical encounters requiring high healthcare utilization or opioid treatment, while maintaining vigilance, more nuanced and sophisticated approaches are needed.

Behavioral economic demand in opioid treatment: Predictive validity of hypothetical purchase tasks for heroin, cocaine, and benzodiazepines.
Behavioral economics provides a framework in which to understand choice and motivation in the field of substance use disorders. Hypothetical purchase tasks (HPT), which indicate the amount or probability of purchasing substances at different prices, have been suggested as a clinical tool that can help predict future substance use and identify targets for intervention. ⋯ This report provides evidence that demand assessment is predictive of future substance use and could help guide treatment planning at intake. These results also demonstrated that the ZBEn model provides good fits to consumption data and allows for sensitive statistical analyses.
