Exploratory study on domain-specific determinants of opiate-dependent individuals' quality of life

Quality of life of services users in psychotropic drug treatment and rehabilitation services: a qualitative study from service user and provider perspectives

Quality of life (QoL) is a widely recognized and valuable social outcome measure in drug treatment and rehabilitation services, but the discrepancies in QoL perceptions between service users and providers remain under-explored. In this study, semi-structured interviews were conducted with service users (n = 22) and providers (n = 29) to capture their perceptions of QoL and explore the similarities and discrepancies between their views. A thematic analysis and contrast exploration revealed a shared understanding of QoL that extends beyond health to six dimensions and prioritizes empowerment and connection. However, divergent views emerged regarding the priorities of material conditions, emotional well-being, and physical health. Findings underscore the importance of using shared decision-making as a strategy to effectively address these discrepancies and promote a more patient-centered approach in treatment and rehabilitation services.

Health-related quality of life in young people: the importance of education

Background

The concept of health-related quality of life and education integrates the bio-psychosocial perspective of health and the multidimensional potentialities of education for wellbeing. This present work is especially relevant to young people because understanding the interaction between health and education can facilitate the design of preventive policies. The research examines the way in which the educational level of young people from an urban district in the city of Zaragoza (Casablanca) has an influence on their health-related quality of life (HRQOL).

Methods

A cross sectional survey was undertaken in the Casablanca district of Zaragoza (Spain). Participants were not randomly selected; their numbers reflected the areas where they lived with respect to age and sex distribution. It comprised 122 boys and 122 girls, aged between16 and 29, living in the neighbourhood are: Viñedo Viejo, Las Nieves and Fuentes Claras. These three residence zones are markedly different in terms of socioeconomic composition. The questionnaire included the following information: socioeconomic characteristics (sex, age, educational level, employment status, residence zone), an assessment of health (health problems, diagnosis and medication in the last 2 weeks) and HRQOL (WHOQOL-BREF dimensions: mental health; physical health; social relations; and environment). ANOVA and four regression models were used to assess the role, direction and intensity of educational level on HRQOL.

Results

The results show that the higher the level of education, the better the level of HRQOL. The biggest impact of education was on the mental health dimension, but this influence was modulated by sex and residence zone. The value of the interaction of education and residence zone was more significant than educational level alone. HRQOL of girls is more sensitive to education, being a student and residence zone than the HRQOL of boys.

Conclusions

The dimensions of HRQOL are influenced by educational level. The influence is greatest among girls and the youngest members of the poorest area of the district. Public authorities should contemplate the development of an equitable education system from the beginning of the life cycle as a public health strategy.

Cognitive function is largely intact in methadone maintenance treatment patients

OBJECTIVES

To confirm our previous findings of less cognitive impairments (based on cognitive screening tools) among methadone maintenance treatment (MMT) patients who achieved take-home dose (THD) privileges.

METHODS

a random sample of 65 Israeli MMT patients were studied using computerised, age and education standardised, cognitive domains (attention, executive function, memory, motor skills), and non-computerised phonetic and semantic verbal fluency.

RESULTS

Cognitive scores were within ±1 standard deviation (SD) of average for most domains, including non-verbal IQ, attention and motor skills. Verbal fluency and memory were >1 SD below average (mean = 84; z = -1.1 for both). Females were younger than the males and had poorer motor skills (P = 0.005) but better verbal memory (P < 0.0005). Opiate usage duration correlated with reaction time (P = 0.05) and inversely with verbal memory (P = 0.01). Overall cognitive function was poorest among 25 (38.5%) current drug users, and 6 (9.2%) lifetime schizophrenia patients. Cognitive domains were comparable between THD privileges subgroups.

CONCLUSIONS

Despite heterogeneity in MMT duration, abuse duration, substance use and psychiatric comorbidity, all performed within ±1 SD of average for age and education in most cognitive domains. Our findings challenge the notion of MMT as being synonymous with compromised cognition and may lead to reduced bias regarding cognitive function of MMT patients.

Chronic pain and opioid abuse: Factors associated with health-related quality of life

BACKGROUND AND OBJECTIVES

While research on the separate relationships between health-related quality of life (HRQOL) and chronic pain, and HRQOL and opioid abuse has been sparse, even less work has investigated the factors associated with HRQOL in individuals who have both chronic pain and meet criteria for opioid use disorder. The data presented in this analysis should allow a better understanding the factors important to quality of life among this dual-diagnosed population.

METHODS

Individuals with dual diagnoses of chronic pain and opioid use disorder were recruited for clinical research studies at Columbia University Medical Center. Participants (n = 47) completed inventories to assess pain (Brief Pain Inventory), opioid (ab)use, and depression (Beck Depression Inventory). Variable from these and other inventories, along with demographic factors (age, race, sex, pain severity, depressive symptoms, duration of opioid use, route of opioid use, amount of opioid use) were entered into a regression analysis in order to identify the strongest predictors of SF-36 Health Survey score.

RESULTS

In the bivariate analysis we found that demographic and drug use variables were rarely associated with HRQOL. Typically, ratings of pain severity and pain interference were the best predictors. In the multivariate analysis, we found that across the several HRQOL dimensions greater Brief Pain Inventory (BPI) ratings of pain "interference" and Beck Depression Inventory (BDI) scores were consistently associated with lower HRQOL.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

These data suggest that insufficient pain management and depression are significant variables contributing to lower quality of life among individuals with chronic pain and opioid use disorder. (Am J Addict 2017;26:815-821).

Quality of life as an outcome of opioid use disorder treatment: A systematic review

BACKGROUND AND AIMS

The recent opioid epidemic has prompted renewed interest in opioid use disorder treatment, but there is little evidence regarding health-related quality-of-life (HRQoL) outcomes in treatment programs. Measuring HRQoL represents an opportunity to consider outcomes of opioid use disorder treatment that are more patient-centered and more relevant to overall health than abstinence alone. We conducted a systematic literature review to explore the extent to which the collection of HRQoL by opioid treatment programs is documented in the treatment program literature.

MATERIALS AND METHODS

We searched PubMed, Embase PsycINFO and Web of Science for papers published between 1965 and 2015 that reported HRQoL outcome measures from substance abuse treatment programs.

RESULTS

Of the 3014 unduplicated articles initially identified for screening, 99 articles met criteria for further review. Of those articles, 7 were unavailable in English; therefore 92 articles were reviewed. Of these articles, 44 included any quality-of-life measure, 17 of which included validated HRQoL measures, and 10 supported derivation of quality-adjusted life year utility weights. The most frequently used validated measure was the Addiction Severity Index (ASI). Non-U.S. and more recent studies were more likely to include a measure of HRQoL.

CONCLUSIONS

HRQoL measures are rarely used as outcomes in opioid treatment programs. The field should incorporate HRQoL measures as standard practice, especially measures that can be used to derive utility weights, such as the SF-12 or EQ-5D. These instruments provide policy makers with evidence on the impact of programs on patients' lives and with data to quantify the value of investing in opioid use disorder treatments.

Girls' quality of life prior to detention in relation to psychiatric disorders, trauma exposure and socioeconomic status

PURPOSE

Practice and research on detained girls has mainly been problem oriented, overlooking these minors' own perspective on and satisfaction with life. The aim of this study was to examine how girls evaluate multiple domains of quality of life (QoL) and how each domain is affected by psychiatric (co)morbidity, trauma, and socioeconomic status (SES).

METHODS

An abbreviated version of the World Health Organization (WHO) QoL Instrument was used to assess the girls' (N = 121; M(age) = 16.28) QoL prior to detention. This self-report questionnaire consists of two benchmark items referring to their overall QoL and health, and 24 remaining items measuring their QoL regarding four domains (physical health, psychological health, social relationships, and environment). The Diagnostic Interview Schedule for Children-IV was used to assess the past-year prevalence of psychiatric disorders and life-time trauma exposure.

RESULTS

Detained girls perceived their QoL almost as good as the 12- to 20-year-olds from the WHO's international field trial on all but one domain (i.e., psychological health). They were most satisfied with their social relationships and least satisfied with their psychological health. Psychiatric disorders, trauma, and low SES were distinctively and negatively related to various domains of QoL. The girls' psychological health was most adversely affected by psychosocial and socioeconomic problems, while these variables had an almost negligible impact on their satisfaction with their social relationships.

CONCLUSIONS

The particularity of each domain of QoL supports a multidimensional conceptualization of QoL. Regarding treatment, psychological health appears as a domain of major concern, while social relationships might serve as a source of resilience.

Effect of a primary care based brief intervention trial among risky drug users on health-related quality of life

BACKGROUND

Improvement in quality of life (QOL) is a long term goal of drug treatment. Although some brief interventions have been found to reduce illicit drug use, no trial among adult risky (moderate non-dependent) drug users has tested effects on health-related quality of life.

METHODS

A single-blind randomized controlled trial of patients enrolled from February 2011 to November 2012 was conducted in waiting rooms of five federally qualified health centers. 413 adult primary care patients were identified as risky drug users using the WHO-ASSIST and 334 (81% response; 171 intervention, 163 control) consented to participate in the trial. Three-month follow-ups were completed by 261 patients (78%). Intervention patients received the QUIT intervention of brief clinician advice and up to two drug-use health telephone sessions. The control group received usual care and information on cancer screening. Outcomes were three-month changes in the Short Form Health Survey (SF-12) mental health component summary score (MCS) and physical health component summary score (PCS).

RESULTS

The average treatment effect (ATE) was non-significant for MCS (0.2 points, p-value=0.87) and marginally significant for PCS (1.7 points, p-value=0.08). The average treatment effect on the treated (ATT) was 0.1 (p-value=0.93) for MCS and 1.9 (p-value=0.056) for PCS. The effect on PCS was stronger at higher (above median) baseline number of drug use days: ATE=2.7, p-value=0.04; ATT=3.21, p-value=0.02.

CONCLUSIONS

The trial found a marginally significant effect on improvement in PCS, and significant and stronger effect on the SF-12 physical component among patients with greater frequency of initial drug use.

Impact of addiction severity and psychiatric comorbidity on the quality of life of alcohol-, drug- and dual-dependent persons in residential treatment

BACKGROUND

Substance users' quality of life (QoL) is influenced by several variables, including psychiatric comorbidity and addiction severity. Thus far, the impact of the type of dependence (alcohol, drug or dual dependence) remains unclear. Therefore, the objectives of the study were to evaluate QoL in a clinical sample of alcohol-, drug- and dual-dependent patients and to assess the independent impact of psychiatric comorbidity, addiction severity and type of dependence on QoL.

METHODS

Face-to-face interviews with 274 patients admitted to residential substance abuse treatment were conducted using the European Addiction Severity Index (EuropASI), the Mini-International Neuropsychiatric Interview and the Assessment of Personality Disorders self-report questionnaire.

RESULTS

Multivariate analyses showed that anxiety, mood or personality disorder, employment status and the severity rating on the EuropASI domain alcohol use were associated with overall QoL. Gender, anxiety disorder and the severity ratings on the EuropASI domains alcohol use, drug use, physical health and emotional and psychological health were associated with overall perception of health.

CONCLUSION

Addiction severity and psychiatric comorbidity explained the greatest amount of QoL variance, whereas the type of dependence did not play a central role.

The experience of long-term opiate maintenance treatment and reported barriers to recovery: a qualitative systematic review

BACKGROUND/AIM

To inform understanding of the experience of long-term opiate maintenance and identify barriers to recovery.

METHODS

A qualitative systematic review.

RESULTS

14 studies in 17 papers, mainly from the USA (65%), met inclusion criteria, involving 1,088 participants. Studies focused on methadone prescribing. Participants reported stability; however, many disliked methadone. Barriers to full recovery were primarily 'inward focused'.

CONCLUSION

This is the first review of qualitative literature on long-term maintenance, finding that universal service improvements could be made to address reported barriers to recovery, including involving ex-users as positive role models, and increasing access to psychological support. Treatment policies combining harm minimisation and abstinence-orientated approaches may best support individualised recovery.

Social network support for individuals receiving opiate substitution treatment and its association with treatment progress

BACKGROUND/AIMS

Social networks have been hypothesized to protect people from the harmful effects of stress, but may also provide dysfunctional role models and provide cues associated with drug use. This study describes the range, type and level of social support available to patients engaged in UK opiate substitution treatment (OST) programmes, and explores the association between network factors and continued use of illicit heroin.

METHODS

A cross-sectional survey of a randomly selected sample of OST patients (n = 118) utilised measures of current substance use and social network structure and support.

RESULTS

More than half of the participants had used heroin in the previous month, and most described networks that were both supportive and positive about treatment. Multivariate analysis showed that the substance use involvement of network members was higher in those patients still using heroin, even when other treatment factors were controlled for.

CONCLUSION

There was a strong association between ongoing contact with other drug users and continued use of illicit heroin in this treatment sample. Whilst there is potential for the involvement of social networks in treatment, future research needs to ascertain the exact nature of the relationship between social support and drug use.

Validation of the English version of the Health-Related Quality of Life for Drug Abusers (HRQoLDA) test

BACKGROUND

The Health-Related Quality of Life for Drug Abusers (HRQoLDA) test was designed to specifically evaluate quality of life among substance users. In this study, the validity and reliability of the English version of the HRQoLDA test are reported for the first time.

METHODS

A sample of 121 participants from inpatient and outpatient treatment facilities completed the HRQoLDA test.

RESULTS

The mean HRQoLDA score was 45.9 (SD = 16.9), while the overall Cronbach's alpha coefficient was 0.905. The factorial analysis of the HRQoLDA test revealed a unidimensional structure. Convergent validity analyses demonstrated significant correlations between the HRQoLDA test scores and the scores of the World Health Organization Quality of Life Assessment-Bref Questionnaire in different dimensions.

CONCLUSION

The results revealed that the HRQoLDA was successfully adapted to English. The HRQoLDA is a reliable research instrument for evaluating quality of life of substance users.
