ABSTRACT The study examined long-term outcomes (mortality, substance use, mental health, employment, criminal involvement) among a cocaine-dependent sample. This 12-year follow-up study, conducted in 2002-2003, updates information obtained at intake and two face-to-face interviews conducted in 1990-1991 and 1991-1992 among 321 male cocaine-dependent veterans admitted to drug treatment in 1988-1989. At the 2002-2003 follow-up, 28 had died and 266 were interviewed. A mixed model examining the longitudinal relationships demonstrated that treatment was associated with lower levels of cocaine use over the 12-year follow-up period after entry into the index treatment and more stable recovery (i.e., continuously abstinent from cocaine for at least 5 years). Few measures at intake predicted stable recovery at follow-up: only being White (vs. being African American) and having greater confidence in ability to avoid cocaine use in high-risk situations. Individuals achieving stable recovery reported less psychiatric symptoms, criminal involvement, and unemployment during the year prior to the interview. Adverse outcomes were apparent for a significant number of cocaine-dependent users who continued to use cocaine for a long period.

    ABSTRACT: Co-occurring cocaine use and posttraumatic stress disorders are prevalent and associated with negative treatment, health and societal consequences. This study examined the relationships among PTSD symptoms, gender, and cocaine use problems. Within a cross-sectional design, we gathered archival point prevalence data on new admissions (n = 573) to three addiction treatment agencies. Demographic, substance use, and PTSD symptom information were collected across the three agencies. Logistic regression analyses revealed that patients with cocaine use disorders had a two-fold increased odds for a probable PTSD diagnosis, compared to patients without a cocaine use disorder (OR = 2.19, 95% CI = 1.49-3.22, p < 0.001). Among females with cocaine use disorder, multinomial regression yielded a significant increase in the risk of moderate (RRR = 2.12, 95% CI = 1.10-4.10, p < 0.05) and severe (RRR = 2.87, 95% CI = 1.33-6.21, p < 0.01) PTSD symptoms. Males with cocaine use disorders had a two-fold increase in the risk of moderate PTSD symptoms (RRR = 2.13, 95% CI = 1.23-3.68, p < 0.01), but had no increased risk of developing severe PTSD symptoms (RRR = 1.93, 95% CI = 0.85-4.39, p = 0.117). Cocaine use appears to impact the risk of PTSD symptoms, especially in females. Future research should explore the generalizability of these findings to more racially and ethnically diverse samples, as well as among persons with this comorbidity who are not engaged in treatment services.

    • "In long-term follow-up studies of persons with substance use disorders, overdose is a leading cause of death (Hser et al., 2006; Jimenez-Trevino et al., 2011). Approximately 48% to 92% of drug users either have experienced a nonfatal overdose or have witnessed an overdose during their lifetime (Seal et al., 2003; Doe-Simkins et al., 2009; Bennett et al., 2011; Walley et al., 2013).

    ABSTRACT: This case study of the development and implementation of an opioid overdose prevention program is based on an actual clinic's experience, but information about the clinic, including details of implementation and outcome measures, has been changed. Four experts reflect on the medical, administrative, peer-support, community, and evaluation aspects of this case. This discussion highlights challenges and important considerations in the creation of programs to address the ever-increasing risk for opioid overdose.

    • "Clearly, these findings highlight the need to identify individuals at risk for SUDs, intervene as early as possible and facilitate a prompt treatment contact and engagement for those with a positive screen for SUDs. While early intervention and treatment engagement are essential to reducing substance use and improving psychological well-being and social functioning among individuals with SUDs, engaging patients in substance abuse treatment is often challenging (Hser et al., 2006; Scott, Foss, & Dennis, 2005). In this study, among those who received a treatment referral, more than a quarter declined to attend treatment services. "

    ABSTRACT: This study examined the relationship between substance treatment referrals and depression improvement among 2,373 participants with concurrent substance use and depressive disorders enrolled in an integrated behavioral health program. Three groups of substance treatment referral status were identified: accessed treatment (n=780), declined treatment (n=315), and no referral for treatment (n=1278). The primary outcome is improvement in depressive symptoms (PHQ-9<10 or≥50% reduction). Using propensity score adjustments, patients accessing substance treatment were significantly more likely to achieve depression improvement than those who declined receiving treatment services (hazard ratio (HR)=1.82, 95% confidence interval (CI): 1.50-2.20, p<0.001) and those without a referral for treatment (HR=1.13, 95% CI: 1.03-1.25, p=0.014). Each 1week delay in initiating a referral was associated with a decreased likelihood of depression improvement (HR=0.97, 95% CI: 0.96-0.98, p<0.001). Study findings highlight the need of enhancing early treatment contact for co-occurring substance use disorders in primary care.
