Interrelationship of Opioid Dependence, Impaired Impulse Control, and Depressive Symptoms: An Open-Label Cross-Sectional Study of Patients in Maintenance Therapy

Examining associations between impulsivity, opioid use disorder, and posttraumatic stress disorder: The additive relation between disorders

Impulsivity is a key feature of opioid use disorder (OUD) and other psychiatric conditions, including posttraumatic stress disorder (PTSD). The relationship between disorders and impulsivity may be additive, such that individuals with multiple disorders exhibit greater impulsivity than those with a single disorder. However, the association between impulsivity, OUD, and PTSD is unclear. Accordingly, this study compared individuals with concurrent OUD and PTSD (OUD + PTSD; n = 55), OUD without PTSD (OUD-PTSD; n = 34), PTSD without OUD (n = 32), and healthy controls (HCs; n = 55) on the Short Urgency, Premeditation, Perseverance, Sensation Seeking, Positive Urgency Impulsive Behavior Scale (SUPPS-P), and the 27-item Monetary Choice Questionnaire (MCQ). With respect to the SUPPS-P, the OUD + PTSD, OUD-PTSD, and PTSD without OUD groups reported more impulsivity on the negative urgency, positive urgency, and lack of premeditation subscales compared to HCs (ps < .001). The OUD + PTSD group also reported greater negative urgency compared to the OUD-PTSD group (p = .001) and HCs (p < .001), but not the PTSD without OUD group (p = .07). Furthermore, participants with OUD + PTSD exhibited greater discounting of delayed rewards on the MCQ than those in the PTSD without OUD group and HCs (p's < .001). However, no significant differences were observed between the two OUD groups (p = .86). These results support impulsivity as a mechanism underlying both OUD and PTSD. Future research should examine whether interventions targeting impulsivity, emotion regulation, and delay discounting are associated with meaningful improvements in functioning among individuals with OUD and PTSD.

Self-rated impulsivity in healthy individuals, substance use disorder and ADHD: psychometric properties of the Swedish Barratt impulsiveness scale

BACKGROUND

Impulsivity is associated with several psychiatric disorders, including substance use disorders (SUD) and attention deficit hyperactivity disorder (ADHD). A widely used questionnaire to assess impulsivity is the Barratt Impulsiveness Scale (BIS), and the aim of the current study was to evaluate the psychometric properties of the Swedish version of the BIS (swe-BIS).

METHODS

The original BIS was translated to Swedish and back-translated by an authorized translator. The swe-BIS was administered to healthy controls (n = 113), patients with alcohol use disorder (n = 97), amphetamine use disorder (n = 37) and attention deficit hyperactive disorder (ADHD; n = 26). A subset of subjects (n = 62) completed the swe-BIS twice within 1 week. Psychometric evaluation of the swe-BIS included assessment of different indices of reliability (internal consistency, test-retest and agreement) and validity (response processess, divergent and convergent). Confirmatory factor analyses (CFA) were performed to assess several indices of model fit in five different models based on previously suggested subscales.

RESULTS

Cronbach's alpha for all swe-BIS items in the full sample was 0.89, ranging from 0.78-0.87 within the different subgroups. The Pearson test-retest correlation for total score was 0.78 (p < 0.001), with greater test-retest correlations within compared to across different subscales. The Bland-Altman plot indicated high level of agreement between test and retest. The healthy individuals had lower swe-BIS score compared to the patients (t(267.3) = - 8.6; p < 0.001), and the swe-BIS total score was also significantly different between each of the four participant groups (p < 0.01 for all group comparisons). Furthermore, swe-BIS had greater correlations with impulsivity related scales compared to non-impulsivity related scales. The CFA analyses indicated that while no suggested model showed an optimal fit, the best model fit indices was found for the 3-factor model.

CONCLUSIONS

The swe-BIS was found to have good to excellent psychometric properties with respect to the assessed indices of reliability and validity, supporting use of the scale in clinical research in both healthy individuals and patients with SUD and ADHD.

Relevance of the dual systems model for predicting drug/alcohol dependence in early adulthood among previously adjudicated young adults

BACKGROUND

While the dual system model has been found to have utility for predicting drug use, examinations have yet to extend to the clinically relevant issue of drug/alcohol dependence. This study sought to provide better understanding of how the dual systems model constructs (impulse control and sensation-seeking) predicted risk for drug/alcohol dependence in early adulthood among a sample of young adults who were adjudicated for a serious offense as minors.

METHODS

Data from several waves of the Pathways to Desistance data were used in analyses. Logistic regression was used to model covariate effects on drug/alcohol dependence risk.

RESULTS

Findings indicated that lower impulse control predicted increased odds of meeting criteria for drug/alcohol dependence in early adulthood. Sensation-seeking was not a significant predictor of drug/alcohol dependence risk at follow-up.

CONCLUSIONS

Lower impulse control was predictive of drug/alcohol dependence risk. Prevention programming should seek to boost impulse control during adolescence to mitigate this risk and treatment programming should focus on impulse control training in order to treat drug/alcohol dependence in inpatient and outpatient contexts.

Opioid use among patients with pain syndromes commonly seeking surgical consultation: A retrospective cohort

BACKGROUND

Surgeons often see patients with pain to exclude organic pathology and consider surgical treatment. We examined factors associated with long-term opioid therapy among patients with foot/ankle, anorectal, and temporomandibular joint pain to aid clinical decision making.

METHODS

Using the IBM MarketScan® Research Database, we conducted a retrospective cohort analysis of patients aged 18-64 with a clinical encounter for foot/ankle, anorectal, or temporomandibular joint pain (January 2007-September 2015). Multivariable logistic regression was used to estimate adjusted odds ratios for factors associated with long-term opioid therapy, including age, sex, geographic region, pain condition, psychiatric diagnoses, and surgical procedures in the previous year.

RESULTS

The majority of the cohort of 1,500,392 patients were women (61%). Within the year prior to the first clinical encounter for a pain diagnosis, 14% had an encounter for a psychiatric diagnosis, and 11% had undergone a surgical procedure. Long-term opioid therapy was received by 2.7%. After multivariable adjustment, older age (age 50-64 vs. 18-29: aOR 4.47, 95% CI 4.24-4.72, p < 0.001), region (South vs. Northeast, aOR 1.76, 95% CI 1.70-1.81, p < 0.001), recent surgical procedure (aOR 1.83, 95% CI 1.78-1.87, p < 0.001), male sex (aOR 1.14, 95% CI 1.12-1.16, p < 0.001) and recent psychiatric diagnosis (aOR 2.49, 95% CI 2.43-2.54, p < 0.001) were independently associated with long-term opioid therapy.

CONCLUSION

Among patients with foot/ankle, anorectal, or temporomandibular joint pain, the risk of long-term opioid therapy significantly increased with older age, recent psychiatric diagnoses and surgical history. Surgeons should be aware of these risk factors in order to make high quality clinical decisions in consultations with these patients.

Doctor shopping among chronic noncancer pain patients treated with opioids in the province of Quebec (Canada): incidence, risk factors, and association with the occurrence of opioid overdoses

Opioid doctor shopping was a rare phenomenon among people living with chronic noncancer pain but was associated with the occurrence of opioid overdoses.

Introduction:

Prescription opioids continue to be involved in the opioid crisis, and a better understanding of factors associated with problematic opioid use is needed.

Objectives:

The aim of this study was to assess the incidence of opioid doctor shopping, a proxy for problematic opioid use, to identify associated risk factors, and to assess its association with the occurrence of opioid overdoses.

Methods:

This was a retrospective cohort study of people living with chronic noncancer pain (CNCP) and treated with opioids for at least 6 months between 2006 and 2017 in the province of Quebec (Canada). Data were drawn from the Quebec health administrative databases. Doctor shopping was defined as overlapping prescriptions written by ≥ 2 prescribers and filled in ≥3 pharmacies.

Results:

A total of 8,398 persons with CNCP were included. The median age was 68.0 (Q1: 54; Q3: 82) years, and 37.1% were male. The 1-year incidence of opioid doctor shopping was 7.8%, 95% confidence interval (CI): 7.2–8.5. Doctor shopping was associated with younger age (hazard ratio [HR] 18–44 vs ≥65 years: 2.22, 95% CI: 1.77–2.79; HR 45–64 vs ≥65 years: 1.34, 95% CI: 1.11–1.63), male sex (HR = 1.20, 95% CI: 1.01–1.43), history of substance use disorder (HR = 1.32, 95% CI: 1.01–1.72), and anxiety (HR = 1.41, 95% CI: 1.13–1.77). People who exhibited doctor shopping were 5 times more likely to experience opioid overdoses (HR = 5.25, 95% CI: 1.44–19.13).

Conclusion:

Opioid doctor shopping is a marginal phenomenon among people with CNCP, but which is associated with the occurrence of opioid overdoses. Better monitoring of persons at high risk to develop doctor shopping could help prevent opioid overdoses.

Adapting an Evidence-Based Home Visiting Intervention for Mothers With Opioid Dependence: Modified Attachment and Biobehavioral Catch-up

Infants born to mothers who are dependent on opioids often have difficulty regulating behavior and physiology at birth. Without sensitive maternal care, these infants are at risk for ongoing problems with self-regulation. Mothers who are dependent on opioids may experience challenges related to their substance use (e.g., unsupportive and/or risky environment, impulse control and reward system problems) that increase the likelihood of insensitive parenting in the absence of effective intervention. In this paper, we describe a home-visiting intervention we have adapted to enhance sensitive, responsive caregiving tailored to the specific needs of mothers with opioid dependence. The original intervention, Attachment and Biobehavioral Catch-up (ABC), was designed for mothers of infants aged 6-24 months who were exposed to early adversity. ABC has been shown to enhance sensitive parenting as well as children's behavioral and biological functioning, with positive outcomes extending into at least middle childhood. Mothers who are opioid dependent need earlier support than provided by ABC because opioid-exposed infants are often vulnerable at birth. The adapted intervention (modified ABC or mABC) includes one prenatal session and one early postnatal session, followed by 10 sessions every 2-3 weeks. In the initial two sessions in particular, mothers are helped to anticipate the challenges of caring for a baby who may be difficult to soothe while nonetheless providing sensitive care. mABC is intended to help mothers see the importance of responding sensitively so as to help infants overcome the developmental risks associated with opioid exposure. Additionally, mABC is structured to support mothers with the challenges of early parenting, especially if the mother herself was not parented sensitively. Throughout, the focus is on helping the mother nurture the distressed infant, attend to the infant's signals, and avoid behaving in overstimulating or intrusive ways. Case examples are presented that highlight both the challenges of working with this population as well as the gains made by mothers.

Purposeful Fentanyl Use and Associated Factors among Opioid-Dependent People Who Inject Drugs

Introduction: In recent years, opioid-related mortality has increased steadily in the United States. Fentanyl, a synthetic opioid, has been a primary driver of the current wave of overdose-related deaths. Little is known, however, about fentanyl use among opioid-dependent people who inject drugs (PWID). We, therefore, sought to characterize purposeful fentanyl use among PWID. Methods: A cross-sectional survey was administrated to 104 opioid-dependent PWID on methadone who self-reported drug- or sex-related risk behaviors. Participants were recruited between July 2018 and October 2019 from a methadone clinic in New Haven, Connecticut. Multivariable logistic regressions were used to identify independent correlates of purposeful fentanyl use. Results: Overall, 43.2% and 22.1% of the participants reported any (lifetime) or recent (past 30 days) purposeful fentanyl use, respectively. Independent correlates of any purposeful fentanyl use were younger age (aOR= 0.94; p = 0.021), recent daily injection (aOR= 3.52; p = 0.047), recent cocaine use (aOR= 3.54; p = 0.041), and moderate/severe depression (aOR= 3.82; p = 0.028). Independent correlates of recent purposeful fentanyl use were moderate/severe depression (aOR= 10.94; p = 0.031), recently sharing injection equipment (aOR= 2.96; p = 0.044), and recently engaging in transactional sex (aOR= 3.60; p = 0.026). Conclusions: These findings indicate that opioid-dependent PWID on methadone remain at increased risk for overdose given the high prevalence of ongoing purposeful fentanyl exposure. Interventions to reduce the harms associated with fentanyl use should target young PWID and active fentanyl users, with an emphasis on achieving adequate methadone dosage and screening and treating depression in methadone-maintained patients who preferentially seek fentanyl.

The Nucleus Accumbens: A Common Target in the Comorbidity of Depression and Addiction

The comorbidity of depression and addiction has become a serious public health issue, and the relationship between these two disorders and their potential mechanisms has attracted extensive attention. Numerous studies have suggested that depression and addiction share common mechanisms and anatomical pathways. The nucleus accumbens (NAc) has long been considered a key brain region for regulating many behaviors, especially those related to depression and addiction. In this review article, we focus on the association between addiction and depression, highlighting the potential mediating role of the NAc in this comorbidity via the regulation of changes in the neural circuits and molecular signaling. To clarify the mechanisms underlying this association, we summarize evidence from overlapping reward neurocircuitry, the resemblance of cellular and molecular mechanisms, and common treatments. Understanding the interplay between these disorders should help guide clinical comorbidity prevention and the search for a new target for comorbidity treatment.

Depression and Anxiety Are Associated With Increased Health Care Costs and Opioid Use for Patients With Femoroacetabular Impingement Undergoing Hip Arthroscopy: Analysis of a Claims Database

PURPOSE

To determine if opioid use and health care costs in the year before and following hip arthroscopy for femoroacetabular impingement (FAI) differ between those with or without depression or anxiety.

METHODS

Using the Truven Health Marketscan database, FAI patients who underwent hip arthroscopy between October 2010 and December 2015 were identified (Current Procedural Terminology codes 29914 [femoroplasty], 29915 [acetabuloplasty], and/or 29916 [labral repair]). Patients were excluded if they had incomplete coverage for 1 year either before or following surgery. The number of patients with 1 or more claims related to depression or anxiety during the year before surgery was quantified (International Statistical Classification Diseases and Related Health-9 codes 296, 298, 300, 309, 311). Health care costs in the year before and following hip arthroscopy were compared between those with or without depression or anxiety. We also compared the number of patients in each group who filled a narcotic pain prescription within 180 days before surgery as well as >60 or >90 days after hip arthroscopy.

RESULTS

Depression or anxiety claims were seen in 5,208/14,830 patients (35.1%) before surgery. A significantly greater proportion of those with preoperative depression or anxiety filled opioid-related prescriptions in the 6 months before surgery (36.2% vs 25.6%, P < .0001) and both >60 days (31.3% vs 24.7%, P < .0001) and >90 days after surgery (29.5% vs 23.4%, P < .0001). The group with preoperative depression or anxiety had significantly greater health care costs both before ($8,775 vs $5,674, P < .0001) and following surgery ($5,287 vs $3,908, P < .0001).

CONCLUSIONS

Both before and following hip arthroscopy, opioid use and health care costs were significantly greater for FAI patients with comorbid depression or anxiety.
