Solving the problem of non‐attendance in substance abuse services

Abstract

Issues. Rates of non-attendance are among the highest in substance misuse services. Non-attendance is costly and results in the inefficient use of limited resources. Patients who frequently miss their appointments have worse outcomes including treatment dropout and decreased likelihood of achieving long-term abstinence. Approach. This narrative review evaluates interventions targeting non-attendance in addiction services and draws upon the wider health-care literature to identify interventions that could be adapted for substance-abusing populations. Key Findings. Both fixed value and intermittent reinforcement contingency management demonstrate potential for improving attendance. However, small sample sizes and heterogeneous populations make it difficult to draw firm conclusions.Appointment reminders by letter or telephone have demonstrated moderate evidence for improving attendance in substance-abusing populations. Text message appointment reminders are extensively utilised in general health-care settings and consistently improve attendance; however, there is a paucity of research examining the feasibility and effectiveness of text message reminders in addiction services. Implications. A lack of evidence for methods to improve attendance is reflected in the continuing challenge faced by addiction services attempting to manage high rates of non-attendance. Conclusions. Non-attendance remains a persistent issue for addiction services.While there is limited evidence that contingency management improves attendance, more rigorous research is needed to determine the optimal intervention components and effectiveness in different populations, particularly those receiving maintenance treatments. Multicomponent text message interventions incorporating different delivery and content strategies demonstrate a promise for improving nonattendance and poor engagement.

Examining the Acceptability of mHealth Technology in HIV Prevention Among High-Risk Drug Users in Treatment

“…This highlights a possibility of incorporating mHealth as an additional strategy to remediate the negative impacts that NCI may cause in various aspects of HIV intervention (e.g., medication adherence, information acquisition and retention, treatment follow-up). It should be noted, however, that careful consideration needs to be given during the design and implementation of such mHealth tools among this high-risk population, including the content of the text messages, the frequency and timing, type of communication (i.e., one-way or two-way communication), the cultural competency of content, the ethical considerations, and the motivation to engage in communication technology [32, 33, 41, 66]. …”

Evasão do tratamento da dependência de drogas: prevalência e fatores associados identificados a partir de um trabalho de Busca Ativa

“…São necessárias estratégias para melhorar o atendimento dos serviços de tratamento do uso abusivo de substâncias, pois essas melhoras podem diminuir desde o absentismo às consultas até o abandono do tratamento. Tais intervenções podem ser tanto clínicas quanto não clínicas, como, por exemplo, a sistematização de lembretes ao paciente, que visam interagir em um ou mais momentos, e que possibilitam um maior engajamento e retenção ao tratamento 22 . Dos pacientes que puderam ser contatados e que retornaram à instituição para a realização da entrevista obtivemos relatos importantes, que permitem trabalhar a favor do seu regresso.…”

Enhancing patient navigation to improve intervention session attendance and viral load suppression of persons with HIV and substance use: a secondary post hoc analysis of the Project HOPE study

“…Inconsistent engagement with health care services is common among individuals with substance use disorders [2]. This is especially problematic for people living with HIV, due to the importance of ongoing engagement in care for optimal health outcomes.…”
