Problem recognition, intention to stop use, and treatment use among regular heroin injectors

Expectations about alcohol, cocaine, and benzodiazepine abstinence following inpatient heroin withdrawal management

BACKGROUND AND OBJECTIVES

Polysubstance use is associated with relapse and poor treatment outcomes among people dependent on heroin. Despite the high prevalence of polysubstance use among patients detoxifying from heroin, little is known about patients' expectations to abstain or use non-opiate substances. The current study examined factors associated with expectations about abstaining from alcohol, cocaine, and benzodiazepines (BZDs) following heroin withdrawal management.

METHODS

Between May and December of 2015, we surveyed 417 patients (71.9% male, 31.7 [±8.39] mean years old) initiating short-term inpatient heroin withdrawal management who reported alcohol, cocaine, or BZD use in the past 30 days. We used logistic regression to evaluate the adjusted associations of background characteristics with expectations about using each substance following discharge.

RESULTS

Approximately half of respondents reported past month alcohol (52%), cocaine (47.0%), or BZD (47.0%) use, and 25.9% reported using all three substances. Approximately half of those reporting drinking, 6.6% reporting cocaine use, and 27% of reporting BZD use expected to abstain from using that substance following heroin withdrawal. Prior opioid withdrawal was associated with a lower likelihood of expecting to stop using alcohol and BZDs, and more days of BZD use was associated with a greater likelihood of expecting to abstain from BZDs following discharge.

CONCLUSION

Persons with opioid use disorder often do not expect to stop using other substances following withdrawal management, with very few planning cocaine cessation.

SCIENTIFIC SIGNIFICANCE

Inpatient heroin withdrawal programs need to address and educate patients about how polysubstance use complicates recovery from heroin use. (Am J Addict 2019;28:36-42).

Alcohol Use Severity and Sexual Risk Behavior Among Female Substance Users

BACKGROUND

Substance use has been identified as one of the leading factors related to HIV transmission in the United States. The association of problematic drinking with sexual risk behavior puts individuals at greater risk for HIV transmission. This may be of particular concern for women given that approximately 66% of new HIV infections occurring through heterosexual transmission are female.

OBJECTIVES

To investigate alcohol use severity and sexual risk behavior among females who use heavy, illicit drugs.

METHODS

Female substances users (N = 251; Mage = 31.90, SD = 7.67; 63.7% Black) self-reported past month alcohol use and lifetime sexual risk behaviors with both casual and steady sex partners.

RESULTS

Problematic alcohol users were more likely to use noninjection drugs and less likely to use injection drugs than abstainers and more likely than moderate alcohol users to use alcohol before/during sex with a steady partner. White problematic alcohol users were less likely to use injection drugs before/during sex with a steady partner than abstainers. Black problematic alcohol users were more likely to use non-injection and alcohol than moderate alcohol users before/during sex with steady partners.

CONCLUSIONS

The current study extends the existing literature by taking a closer look at the role of alcohol use severity in sexual risk taking behavior of Black and White female substance users, a particularly vulnerable group for HIV transmission.

Religiosity as a Predictor of Adolescents' Substance Use Disorder Treatment Outcomes

BACKGROUND

A growing body of research on adults with substance use disorders (SUDs) suggests that higher levels of religiosity and/or spirituality are associated with better treatment outcomes. However, investigation into the role of religiosity and spirituality in adolescent SUD treatment response remains scarce. The present study examines religiosity as a predictor of treatment outcomes in an adolescent sample, with alcohol/other drug problem recognition as a hypothesized moderator of this relationship. Problem recognition was selected as a moderator in an attempt to identify a subset of adolescents who would be more likely to use religious resources when attempting to change their substance use.

METHODS

One hundred twenty-seven outpatient adolescents aged 14 to 19 (Mage=16.7, SD=1.2, 24% female) were followed for 1 year after treatment intake. Growth curve analyses were used to assess the impact of baseline religiosity and problem recognition on subsequent abstinence rates, drug-related consequences, and psychological distress.

RESULTS

On average, abstinence did not change significantly during the follow-up period, whereas drug-related consequences and psychological distress decreased significantly. Religiosity did not predict changes in abstinence or psychological distress over time. Religiosity did predict reductions in drug-related consequences over time (b=-0.20, t=-2.18, P=.03). However, when problem recognition was added to the model, the impact of religiosity on consequences became nonsignificant, and there was no interaction between religiosity and problem recognition on consequences.

CONCLUSIONS

The main hypothesis was largely unsupported. Possible explanations include that the sample was low in religiosity and few participants were actively seeking sobriety at treatment intake. Findings suggest adolescent outpatients with SUD may differ from their adult counterparts in the role that religiosity plays in recovery.

Patterns of abstinence or continued drug use among methadone maintenance patients and their relation to treatment retention

The efficacy and effectiveness of methadone maintenance treatment (MMT) in the medical management of opioid addiction has been well-established, but treatment outcomes are compromised by the continued use of licit and illicit drugs during MMT. The present study examined the relationship between in-treatment illicit drug use and retention and dropout of 604 MMT patients in Washington, D.C. Sixty-eight percent of patients did not test positive for an unprescribed drug during the study period. Of patients who tested positive for an illicit drug during the baseline period, 55% tested positive for cocaine, 44% for opiates, 23% for THC, 20% for benzodiazepines, 7% for PCP, and 4% for amphetamines. Those testing positive were three times more likely to leave treatment than those who did not test positive. Testing positive for one drug doubled the rate of attrition; testing positive for multiple drugs quadrupled the risk of attrition. Non-prescribed opioid or benzodiazepine use was a predictor of MMT dropout, but prescribed opioid or benzodiazepine use was not. Continued illicit drug use poses significant risk for subsequent premature termination of MMT. Assertive clinical management of continued illicit drug use could provide mechanisms to enhance MMT retention and long-term recovery outcomes.

A latent class approach to treatment readiness corresponds to a transtheoretical ("Stages of Change") model

Motivation for treatment among people with substance use problems is an important aspect of treatment success. Models for treatment motivation are widely debated. Latent Class Analysis can help to demonstrate the appropriateness of available models. The current study utilizes Latent Class Analysis to analyze treatment readiness statements as they relate to the reduction or cessation of marijuana, cocaine, and opioid use among 539 cocaine and opioid users recruited from the community of Baltimore, MD, USA. Participants completed an in-person structured interview including demographic questions, a treatment readiness questionnaire with items on Intention to Stop Use (ISU) and Problem Recognition (PR), current substance abuse treatment utilization, and urinalysis testing for marijuana, cocaine, and heroin. Latent class models were fit to the treatment readiness questionnaire. A four-class model provided the best fit with one class low on both ISU and PR ("Pre-contemplative"), a second class low on ISU but high on PR ("Contemplative"), a third class high on both ("Preparation/Action"), and a final class high on ISU but low on PR ("Post-Action"). Compared to the "Contemplative" class, the "Pre-contemplative" class was significantly more likely to be positive for marijuana, and the "Post-Action" class was significantly less likely to be positive for opioids. The "Preparation/Action" class was significantly more likely to be in treatment. With the exception of the "Post-Action" class, the analysis appears similar to the "Stages of Change" model and suggests that problem recognition and intention to stop use are important domains in the model. However, further longitudinal research is needed to assess predictive validity of model.
