Factors predicting drop out from, and retention in, specialist drug treatment services: a case control study in the North West of England

Relapse during opioid use disorder treatment: A pilot study to understand the reasons for opioid use during treatment

Background

Opioid use is a cause of concern in many parts of the world. About 2.1% Indians use opioids. Opioids are also the most common drugs used by injection drug users in India. Despite various treatment strategies used to manage opioid use disorders (OUDs), relapse is common. A good treatment program would make efforts to address lapses and prevent relapse. Hence, there is a need to understand the factors associated with relapse in OUD.

Method

One hundred and twenty patients completed a baseline assessment that included socio-demographic details and the Maudsley Addiction Profile (MAP). They were followed up for three months and assessed using telephonic interview for opioid use. All those who relapsed were assessed using the Reasons for Relapse Questionnaire (RRQ). The patients who relapsed were compared with the patients who were abstinent. Relapse was defined as any use of opioid during follow-up.

Results

Forty participants relapsed during the 90 days of the study period. Relapsed patients had a greater number of conflict days with family members, used a higher amount of heroin and cannabis at baseline, were less likely to be discharged on buprenorphine, and were more likely to drop out. Participants cited mood and social reasons more often than cue/craving and unwell domains of RRQ.

Conclusion

Baseline treatment and prospective factors are associated with relapse in OUD. Addressing these factors can help in reducing relapse in OUD patients.

Effects of a brief pre-admission telephone reminder on no-show and dropout rates in substance use disorder treatment: a quasi-experimental study

Background

Appointment no-show and early dropout from treatment represent major challenges in outpatient substance use disorder treatment, adversely affecting clinical outcomes and health care productivity. In this quasi-experimental study, we examined how a brief reminder intervention for new patients before their first appointment affected treatment participation and retention. No-shows (not attending any sessions) and dropouts (discontinuation of initiated treatment because of three consecutively missed appointments) were compared between a period with pre-admission telephone calls (intervention) and a period without such reminders (non-intervention).

Methods

Participants were all eligible patients (N = 262) admitted to a Norwegian specialist clinic for substance use disorder treatment. We used the Chi-square test for the no-show analysis. Of the eligible patients, 147 were included in a subsequent dropout analysis. We used the number of visits up to 10 appointments as a measure for time to event. Group differences were analyzed using a Kaplan–Meier plot and the log-rank test. To control for relevant sociodemographic variables, as well as substance use and mental distress severity, we used Cox regression.

Results

No-show rates did not differ between the two periods (12% for non-intervention vs. 14% for intervention; χ2 = 0.20, p = 0.653). Of those consenting to participate in the dropout analysis (n = 147), 28 (19%) discontinued treatment within the time frame of 10 appointments, with no differences between the two periods (log-rank test = 0.328, p = 0.567). Controlling for baseline characteristics did not alter this finding. In fact, of the registered covariates at baseline, only higher education level was associated with attrition, linked to a reduced risk for dropout (hazard ratio = 0.85, 95% CI = 0.74–0.98, p = 0.025).

Conclusion

These findings do not provide support for the systematic use of a brief pre-admission telephone reminder in the current treatment setting.

Trial registration

The study was retrospectively registered 13 Jan 2021 at ClinicalTrials.gov, NCT04707599.

Initial treatment dropout in patients with substance use disorders attending a tertiary care de-addiction centre in north India

Background & objectives:

Dropout from substance use disorders treatment is associated with poor outcomes. Although many factors have been associated with an early dropout of patients, the reasons for dropping out of treatment prematurely remain poorly understood particularly in the Indian context. This study was aimed to study socio-demographic and clinical variables predicting initial dropout of patients attending a tertiary care de-addiction treatment centre in north India.

Methods:

Information was extracted from the records of consecutive newly registered patients from January 2011 to December 2014. The patients who did not come for follow up within 30 days of the first contact were defined as initial dropouts.

Results:

Data of 7991 patients could be retrieved. Majority of the sample consisted of male, married and employed individuals. Of them, 4907 patients (61.3%) were considered initial dropouts. Multivariate analysis revealed that after controlling for other factors, greater age, being employed, lower educational status, lesser duration of substance use, use of alcohol, opiate, tobacco, cannabis or sedative-hypnotic use but the absence of multi-substance use predicted initial drop out.

Interpretation & conclusions:

This study identified some socio-demographic and clinical variables which might predict treatment attrition in substance use disorders. Clinician's awareness towards these factors and tailor-made intervention might improve initial treatment retention. Future research could be directed to find the validity of this assumption.

Young adults' reasons for dropout from residential substance use disorder treatment

Dropout from substance use disorder treatment is usually investigated and understood from a perspective of quantitative patient-related factors. Patients' own perspectives (user perspective) are rarely reported. This study, therefore, aimed to explore patients' own understanding of their dropout from residential substance use disorder treatment. The participants were 15 males and females, aged 19-29 years, who had dropped out of residential substance use disorder treatment at the Department of Addiction Treatment, Oslo University Hospital, Norway. Qualitative methodology with semistructured interviews was used to explore how the participants described their dropout and their reasons for doing so. Thematic analysis was used as the framework for analyzing the data derived from the interviews. Dropout had different meanings for different participants. It was understood as a break from treatment, as an end to treatment, or as a means of reduced treatment intensity. Against that background, four main themes for dropout were found: drug craving, negative emotions, personal contact, and activity. Patient and treatment factors seem to interact when participants explore reasons for their dropout. A complex pattern of variables is involved. As remedies, participants suggested that substance use disorder treatment should provide more focus on drug craving and training to understand and tolerate emotional discomfort. They also wanted closer contact with the staff during treatment, more activities, and rigorous posttreatment follow-up. These findings from the user perspective have important implications for substance use disorder treatment, clinical and social work practice, management, and research.

Psychometric properties of the Persian version of the Time to Relapse Questionnaire (TRQ) in substance use disorder

BACKGROUND

Predicting time to relapse provides an opportunity for the development of relapse prevention interventions in drug users.

OBJECTIVES

The aim of the present study was to describe the development of the Persian version of the 9-item Time to Relapse Questionnaire (TRQ) and to evaluate its psychometric properties in an Iranian sample of treatment-seeking individuals with substance dependence (n = 150).

METHODS

The forward-backward method was used to translate the TRQ scale from English into Persian. After linguistic validation and a pilot check, a cross-sectional study was performed, and psychometric properties of the Iranian version of the questionnaire were assessed. The reliability was evaluated by Cronbach's alpha and test-retest analyses. In addition, the factor structure of the scale was extracted by applying confirmatory factor analysis.

RESULTS

The mean age of participants was 40.52 (SD = 11.30) years. The mean scores for the content validity index (CVI) and the content validity ratio (CVR) were 0.93 and 0.81, respectively. A confirmatory factor analysis (CFA) demonstrated that the three-factor model of the TRQ was a good fit for the data and thus replicated the factor structure of the original English language TRQ. Cronbach's alpha presented good internal consistency (alpha = 0.76), and test-retest reliability of the TRQ instrument with 2-week intervals was appropriate (ICC = 0.84).

CONCLUSION

The findings demonstrate that the Persian version of the TRQ is a reliable and valid scale for measuring time to relapse in Iranian drug users. The TRQ can be applied at the start of treatment so that clinical interventions can be targeted toward the different relapse styles.

Experiences from a community based substance use treatment centre in an urban resettlement colony in India

Background. There are limited community based treatment services for drug dependence in India. Rural areas and urban resettlement colonies are in particular deficient in such services. Aims. The current study aimed at preliminary assessment of substance use disorder management services at a community based substance use treatment clinic in an urban resettlement colony. Methods. The study was carried out at community based substance use treatment centre in a resettlement colony in India. The records of the centre were chart reviewed. Results. A total of 754 patients were registered at the clinic during the study period. Heroin was the primary drug of abuse for 63% of the patients. The mean duration of follow-up for the patients with opioid and alcohol dependence was 13.47 (SD ± 10.37; range 0–39) months. A total of 220 patients of opioid dependence were prescribed substation or abstinence directed therapy. Buprenorphine (87), slow release oral morphine (SROM) (16), and dextropropoxyphene (98) were used for opioid substitution. Conclusion. It is possible to deliver substance use disorder treatment services in community setting. There is a need to develop area specific community based treatment services for substance abuse in socially disadvantaged populations such as urban resettlement colonies.

Methadone treatment for HIV prevention-feasibility, retention, and predictors of attrition in Dar es Salaam, Tanzania: a retrospective cohort study

BACKGROUND

People who inject drugs (PWID) in Dar es Salaam, Tanzania, have an estimated human immunodeficiency virus (HIV) prevalence of 42%-50% compared with 6.9% among the general population. Extensive evidence supports methadone maintenance to lower morbidity, mortality, and transmission of HIV and other infectious diseases among PWID. In 2011, the Tanzanian government launched the first publicly funded methadone clinic on the mainland of sub-Saharan Africa at Muhimbili National Hospital.

METHODS

We conducted a retrospective cohort study of methadone-naive patients enrolling into methadone maintenance treatment. Kaplan-Meier survival curves were constructed to assess retention probability. Proportional hazards regression models were used to evaluate the association of characteristics with attrition from the methadone program.

RESULTS

Overall, 629 PWID enrolled into methadone treatment during the study. At 12 months, the proportion of clients retained in care was 57% (95% confidence interval [CI], 53%-62%). Compared with those receiving a low dose (<40 mg), clients receiving a medium (40-85 mg) (adjusted hazard ratio [aHR], 0.50 [95% CI, .37-.68]) and high (>85 mg) (aHR, 0.41 [95% CI, .29-.59]) dose of methadone had a lower likelihood of attrition, adjusting for other characteristics. Older clients (aHR, 0.53 per 10 years [95% CI, .42-.69]) and female clients (aHR, 0.50 [95% CI, .28-.90]) had a significantly lower likelihood of attrition, whereas clients who reported a history of sexual abuse (aHR, 2.84 [95% CI, 1.24-6.51]) had a significantly higher likelihood of attrition.

CONCLUSIONS

Patient retention in methadone maintenance is comparable to estimates from programs in North America, Europe, and Asia. Future implementation strategies should focus on higher doses and flexible dosing strategies to optimize program retention and strengthened efforts for clients at higher risk of attrition.

[Factors Associated With the Temporary Abandonment of Treatment for Disorders Due to Substance Abuse in an Institution in Medellin, Colombia]

OBJECTIVE

To determine the frequency and factors associated withtreatment drop-out in patients from a Substance User Treatment Center in Medellín, Colombia.

METHODS

A case-control study was conducted, with patients with an early treatment dropout as cases, and patients who completed the treatment as controls. Demographic data, substance use pattern, concomitant diseases, and the decision to initiate treatment were compared between cases and controls.

RESULTS

The frequency of early drop-out was 59%, but a high proportion of this drop-out (47.5%) occurred in the transition period between the program stages. The variables associated with drop-out were: psychotic disorder (OR=0.32; 95% CI, 0.11-0.91), bipolar disorder (OR=0.31; 95% CI, 0.12-0.77), heroin as the principal substance compared to alcohol (OR=6.68; 95% CI, 1.52-29.4), decision to initiate the treatment by the family compared to personal decision (OR=3.02; 95% CI, 1.28-7.17), and previous treatments (OR=1.87; 95% CI, 1.02-3.44).

CONCLUSIONS

The drop-out frequency is similar to those reported in other studies. Associated factors were found, which could be considered in order to plan strategies to improve the program results.

Retention in methadone maintenance treatment in mainland China, 2004-2012: a literature review

BACKGROUND

Methadone maintenance treatment (MMT) was implemented in mainland China since 2004. Numerous individual studies have investigated MMT retention but the overview still remains unclear. The aim of the study was to review MMT retention rates and predicting factors in mainland China during 2004-2012.

METHODS

Chinese and English databases of literature were searched for studies reporting on retention rates and predicting factors in non-transfer MMT patients of fixed-site clinics in mainland China (2004-2012). Qualitative methods were used to synthesize the results.

RESULTS

Nineteen studies were eligible for review, with sample size ranging from 29 to 3758. Retention rates varied between 30.0% at 6 months in Shanghai and 70.3% at 12 months in Xi'an. Predicting factors were non-treatment including sociodemographics (n=14), support system and social function (n=9), economic status (n=2) and psychological status (n=1), and treatment-related including drug use (n=15), methadone use (n=12), MMT clinics (n=9), MMT participation (n=7), awareness on MMT (n=5) and HIV serostatus (n=3). Methadone dose (n=12) and age (n=7) were the first two important specific factors.

CONCLUSIONS

In mainland China, MMT retention rates are heterogeneous and relatively lower, and predicting factors mainly focus on objective aspects. Future work should further explore subjective predicting factors regarding MMT retention.

Drop-out from addiction treatment: a systematic review of risk factors

Completion of addiction treatment is one of the most consistent factors associated with a favorable treatment outcome. Unfortunately, it is more common for a patient to drop-out of addiction treatment than to complete the treatment. To prevent drop-out, risk factors must be identified. This box-score review focuses on studies investigating the risk factors associated with drop-out from addiction treatment published in peer-reviewed journals from 1992 to 2013. A total of 122 studies involving 199,331 participants met the inclusion criteria. Contrary to recommendations from previous reviews, 91% of the included studies focused primarily on enduring patient factors, mainly demographics. The most consistent risk factors across the different study designs, samples, and measurement methods were cognitive deficits, low treatment alliance, personality disorder, and younger age. With the exception of younger age, none of the demographic factors emerged as consistent risk factors. Further research on the relationship between simple demographic factors and drop-out risk is of limited value. However, little is known about the potential risk factors related to treatment programs and to the treatment processes. Based on the review, clinical recommendations include assessing cognitive functioning and personality disorders at baseline and continuous monitoring of treatment alliance.

Drop out from out-patient mental healthcare in the World Health Organization's World Mental Health Survey initiative

BACKGROUND

Previous community surveys of the drop out from mental health treatment have been carried out only in the USA and Canada.

AIMS

To explore mental health treatment drop out in the World Health Organization World Mental Health Surveys.

METHOD

Representative face-to-face household surveys were conducted among adults in 24 countries. People who reported mental health treatment in the 12 months before interview (n = 8482) were asked about drop out, defined as stopping treatment before the provider wanted.

RESULTS

Overall, drop out was 31.7%: 26.3% in high-income countries, 45.1% in upper-middle-income countries, and 37.6% in low/lower-middle-income countries. Drop out from psychiatrists was 21.3% overall and similar across country income groups (high 20.3%, upper-middle 23.6%, low/lower-middle 23.8%) but the pattern of drop out across other sectors differed by country income group. Drop out was more likely early in treatment, particularly after the second visit.

CONCLUSIONS

Drop out needs to be reduced to ensure effective treatment.

The effects of the macro-environment on treatment retention for problem cocaine users

BACKGROUND

Client dropout is commonly used as an indicator of quality and effectiveness of drug treatment. Following increasing cocaine use in recent years, research has attempted to identify predictors of retention in treatment for cocaine users but there is no consensus about how individual characteristics and system variables (referral source, treatment setting), what we term here as the "macro-environment" - effect risk of dropout. This study sought to identify macro-environmental factors and examine the way these impact upon treatment retention.

METHODS

A retrospective longitudinal study of an admission cohort among drug services in Vasta Romagna in Emilia Romagna Region, Italy (up to 8 years of treatment or until discharge) was conducted to determine the effect of macro-environmental variables on retention among first time admitted cocaine-dependent clients in different treatment settings. The sample consisted of 1178 clients meeting DSM-IV-R criteria for cocaine dependence.

RESULTS

The joint effect of individual and system factors had a significant impact on dropout rates. In particular, lower rates of dropout were observed for those treated in prison and those who had a stable home, HR: 0.09 (0.02-0.48), or lived in rehabilitation units, HR: 0.36 (0.15-0.88), and among clients referred by the local authority and those living with parents, HR: 0.60 (0.38-0.95).

CONCLUSION

The combined effect of individual and system factors on retention in treatment sets a critical background necessary to assess any impact of organizational dynamics and delineate the trajectory for future interventions.

Perfil clínico e sociodemográfico de adolescentes que permaneceram e não permaneceram no tratamento em um CAPSad de Cuiabá/MT

OBJETIVO: Comparar o perfil clínico e sociodemográfico dos adolescentes que permaneceram e que não permaneceram no tratamento no Centro de Atenção Psicossocial para Álcool e outras Drogas (CAPSad). MÉTODO: Estudo transversal, baseado no registro de prontuários de 125 usuários que estiveram em tratamento no CAPSad Adolescer em Cuiabá/MT, no período de junho de 2009 a junho de 2011. RESULTADOS: A permanência no tratamento foi predominante no sexo masculino, entre usuários que fizeram uso pesado de substâncias psicoativas, encaminhados ao serviço pelos setores social e judicial, que possuíam relação familiar conflituosa e que tinham a participação frequente da família no tratamento. A maior proporção dos que não permaneceram ocorreu na falta de integração do serviço com outros dispositivos da rede. CONCLUSÃO: Os achados deste estudo sobre as características dos adolescentes e os fatores intervenientes na permanência reforçam a responsabilidade do CAPS na efetivação da articulação da rede, além de reafirmar que a família deve ser cada vez mais aproximada do tratamento, sendo parte fundamental no projeto de intervenção.

The Psychosocial Treatment Expectations Questionnaire (PTEQ) for Alcohol Problems

High dropout rates from treatment for alcohol-related problems are a problem for treatment delivery. Outcome expectations of treatment attendance are motivational aspects of treatment adherence. Since no method to put such expectations into operation has been found, we developed the Psychosocial Treatment Expectations Questionnaire (PTEQ) to assess the expectations of people receiving such psychosocial treatments. PTEQ development and early validation relied on data from 151 clients. A two-dimensional questionnaire assessing treatment purpose and atmosphere, and impact on daily life was developed, showing acceptable levels of reliability (α = 0.85 for the overall score, and 0.80 and 0.77 for the two scales, respectively). The PTEQ overall score significantly detected differences in expectations between those who remained in, and those who dropped out of treatment. On average, the dropouts had lower treatment expectations than those who remained in treatment. Validity for populations other than alcohol misusers and for treatments delivered exclusively through individual sessions, needs to be further examined.
