Prescribed opioids are a mainstay pain treatment after traumatic injury, but a subgroup of patients may be at risk for continued opioid use. We evaluated the predictive utility of a traditional screening tool, the Opioid Risk Tool (ORT), and two other measures: average in-hospital milligram morphine equivalents (MME) per day and an assessment of opioid demand in predicting pain outcomes. Assessments of pain-related outcomes (pain intensity, interference, injury-related stress, and need for additional pain treatment) were administered at 2 weeks and 12 months post-discharge in a sample of 34 patients hospitalized for traumatic injury. Bayesian linear models were used to evaluate changes in responses over time as a function of predictors. High-risk ORT, higher MME per day, and greater opioid demand predicted less change in outcomes over time. This report provides first evidence that malleable factors of opioid and opioid demand have utility in predicting pain outcomes following traumatic injury. [ABSTRACT FROM AUTHOR]

Summary People who use substances commonly experience sleep disruptions, affecting the regulation of physical and mental health, and presenting a significant barrier to treatment success. Sleep impairments are noted in all phases of substance use; however, differences between subjective versus objective methods used to measure sleep quality have been reported. While polysomnography is the gold‐standard for sleep measurement, recent advances in actigraphy may help address the discordance between subjective and objective sleep reports. This systematic review examined emerging evidence (2016–present) for sleep impairment in people who use substances, with the twofold goal of: (1) identifying whether sleep outcomes vary across substance type (alcohol, nicotine, cannabis, cocaine, methamphetamine and opioids); and (2) contrasting results from subjective and objective measures. While some differences between subjective and objective sleep were noted, there was overwhelming evidence of clinically relevant sleep impairment in people who use alcohol, nicotine, cocaine, methamphetamine and opioids, with less consistent results for cannabis. Gaps in the literature are identified and future recommendations are presented, including utilization of common methodological frameworks, identification of mechanisms, and closer examination of sleep across stages of substance use and the interconnection between sleep and return to use.

Cocaine use disorder (CUD) is a major public health issue, and greater cocaine use severity has been associated with worse treatment retention and outcomes. Therefore, greater understanding of processes that influence cocaine use is needed. Both anhedonia (i.e., undervaluation of nondrug rewards) and cocaine demand (i.e., cocaine valuation) are related to cocaine use severity and thematically related to each other at face value, but no studies have directly compared these outcomes to our knowledge. The present study represents a secondary analysis from a two-phase sequential, multiple assignment, randomized trial aimed at developing adaptive interventions for CUD. We examined the relationship between anhedonia and cocaine demand and how these measures were related to cocaine use severity. Participants ( N = 116) were treatment-seeking adults with CUD. All measures were taken at baseline before treatment initiation. Analyses revealed (a) moderate and very strong evidence of relationships between cocaine demand factors (i.e., persistence, amplitude) and anhedonia (PP values ≥ 77.8%); (b) positive association between cocaine demand (both persistence and amplitude) and measures of cocaine use severity, with the exception of one relationship, which was in the opposite direction; and (c) demand amplitude continued to be positively related to cocaine use severity, even when considering anhedonia. Overall, findings from this study indicate cocaine demand relates to cocaine use severity more strongly than anhedonia. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Although it is an effective HIV prevention method, pre-exposure prophylaxis (PrEP) is underutilized in the Southern US. Many people who use drugs (PWUD) have increased susceptibility to HIV which could be lessened by using PrEP. Potential barriers to PrEP use include lack of awareness of PrEP, low knowledge about HIV prevention, low self-efficacy for HIV prevention, inaccurate risk perceptions, and anticipated stigma. The current study examined predisposing, enabling, and reinforcing factors that may predict interest in PrEP. The purpose of the current study was to explore factors associated with interest in and willingness to use daily oral and long acting injectable PrEP among sexually active adult PWUD. The data were collected from adult participants (n = 270) residing in Harris County, TX, who self-reported problematic substance use and who reported oral, anal, or vaginal sex in the six months prior to completing the survey. The survey was distributed and completed online via Qualtrics Panels in March of 2022 and included measures of PrEP and HIV knowledge, PrEP stigma, sexual health self-efficacy, experiences of discrimination, health literacy, and medical mistrust. The majority of participants reported circumstances or behaviors that increased their susceptibility to HIV. Findings indicated that PrEP user stereotypes and PrEP anticipated disapproval by others were associated with interest in using daily oral PrEP and willingness to use long acting injectable PrEP. These results provide insight into reasons for low PrEP uptake among PWUD who live in a high HIV prevalence jurisdiction. Implications for HIV prevention intervention are discussed., (© 2024.
