A US inpatient treatment centre has shown that systematically applying simple prompts and motivators can substantially improve aftercare attendance and help sustain progress made during initial treatment. The findings offer a way to preserve the benefits of the investment made by patients, services, and funders.
FINDINGS The Salem Veterans Affairs medical centre offers a 28-day residential rehabilitation programme to its alcohol and/or drug dependent ex-military patients. To sustain sobriety, staff stressed the importance of aftercare but attendance was poor. A unique series of studies1 had previously shown that attendance radically improved as step by step researchers added enhancements, culminating in a report which suggested But the samples were small and results barely significant. that there were consequent reductions in drinking and related problems.
A further study2 has now tested the impact of the entire package Plus further enhancements, termed in the study Contracting, Prompting and Reinforcing (CPR) continuing substance abuse treatment. on aftercare attendance and more robustly assessed changes in substance use. 150 eligible patients agreed to join the study and were randomly allocated to the centre's standard procedure or to the enhanced package. During the final days of their stay, standard procedure patients were encouraged to attend the centreís aftercare groups and individual sessions, as well as mutual aid groups such as NA and AA. Initial appointments and/or attendance schedules were agreed and listed in an aftercare 'contract' handed to the patient, who was also shown a motivational video.
For the enhanced version, the contract was strengthened by asking patients to commit in writing (witnessed by the therapist) to over the next eight weeks The aim was to retain patients for at least three months of treatment overall, the minimum associated with improved outcomes in this population. attend weekly groups and AA/NA meetings and monthly individual sessions. Veterans Affairs' data showing that aftercare attendance was associated with abstinence was used to motivate agreement. Therapists also explained the reminder system and showed patients the awards (see next paragraph) for attendance specified in the contract. After eight weeks patients were invited to re-contract to continue in aftercare for eleven months in total.
Letters from the therapist, Saying they were pleased the patient had chosen to join their group and that they looked forward to seeing them. appointment cards Which also tallied the patientís attendance to date. and automated telephone reminders prompted patients to attend the next session in a few days time. Non-attendance was followed by a letter and phone call from the therapist. Awards consisted of medallions and certificates handed out during individual aftercare sessions. Further reinforcement took the form of a handwritten letter congratulating the patient on initiating aftercare followed by another after three sessions.
Researchers Unaware of to which procedure patients had been allocated. were able to re-assess around 80% of patients two, five and 11 months after they left treatment, reassuring them that their responses Urinalysis results confirmed the accuracy of their answers regarding substance use. were confidential. Compared to the standard procedure, the enhancements led 12% (95% v. 83%) more patients to initiate aftercare and nearly 30% more (75% v. 45%) to attend at least two sessions a month over the first two months. Attendance tailed off until after five months just 20–25% remained continuously in aftercare and after 11 months 12–13%. Nevertheless, nearly twice as many intervention patients attended aftercare at some time during the last three months of the follow-up (40% v. 22%).
This persisting attendance advantage appeared to account in part for impacts on substance use. Eleven months after leaving treatment, nearly 20% more (57% v. 37%) enhanced patients had been abstinent In contrast, the average intensity of substance use did not differ between the two sets of patients and nor generally did the severity of related problems. from alcohol and drugs for the past three months. The difference had grown over the preceding six months as more of these patients stopped using.
IN CONTEXT Because the centre served ex-military personnel there were very few women. All the studies excluded participants who would have had significant difficulty Due to distance, lack of transport or work commitments. Eliminating these practical barriers probably allowed the influence of the interventions to show through so clearly. attending an aftercare centre.
The highest attendance gains were observed while contracting and rewarding procedures were also at their height (the first two months) and for the type of aftercare provision (the centre's own sessions) most explicitly targeted. From the prior studies, we know that each of the elements in the package added to its impact. Involving the patients themselves in formulating the contract seems likely to have deepened their commitment to fulfilling it. By signing it they acknowledged research indicating that aftercare tripled the chances of staying sober. Refusing would have meant admitting to themselves and to their therapist that they did not wish to improve their chances in this way. Phone calls and personal, handwritten letters from therapists signified individual attention and that someone cared enough to notice the patient's achievements and to bother when they went missing.
The pattern of abstinence outcomes suggests that intervention patients, systematically encouraged and prompted to stay in or return to aftercare, felt more inclined to seek help after they lapsed or relapsed. A welcoming, non-punitive ('Come back – we'd like to see you.') attitude would have made it easier. The result it seemed was that more resumed abstinence over the last months of the follow-up.
Gains from the enhanced package might have been greater still if awards had been made in front of peers This was trialed in one of the earlier studies but in the featured study the opportunity had to be foregone because some of the patients in each group would have been from the standard care set. at group therapy sessions and if it had replaced typical procedures. Even the standard comparator was an advance on the most basic procedure tested in an earlier study and probably also on what typically happens to encourage aftercare attendance.
Earlier studies from Salem and related work were reviewed by Drug and Alcohol Findings in parts one3 and two1 of the Manners Matter series. These concluded that treating the patient as an individual, being welcoming, and showing respect and caring persistence, are among the hallmarks of services which retain clients. The reviews argued that there is no conflict between these qualities and efficient administrative procedures of the kind used to deliver reminders in the featured study. Such procedures are needed to give practical expression to the qualities and values which motivate them. In turn, these procedures will not have the desired impact unless they express these qualities; a cold or standardised reminder letter signifies that the sender cares little about the individual and whether they turn up or not. Personal approaches are more effective.

PRACTICE IMPLICATIONS The interventions are practical In terms of low staff time and resource commitment and simplicity of implementation. and probably also widely acceptable because they involve neither material rewards nor material or other sanctions. Behind them is the principle of prompting and rewarding attendance directly and immediately rather than expecting this to be motivated entirely by the patient's interest in their long-term recovery.
If (strongly argued in some quarters) Britain is to re-balance its treatment system to offer more residential treatment slots, aftercare provision and encouragement of the kind trialed in the study will be crucial to help avoid or overcome relapse and to sustain support for services which might otherwise be seen as costly revolving doors. Residential settings radically alter the patient's environment, enabling residents who would otherwise be unable to do so to attain abstinence. By the same token, relapse is likely when they return to the environment in which they were previously unable to stop using, unless steps have been taken to alter this, or to sustainably alter how the patient reacts to it. For heroin dependent patients in particular, aftercare is needed to reduce the risk of overdose due to relapse at a time when the patient has lost their tolerance to opiate-type drugs. In the English NTORS study,4 within a fortnight of leaving residential or inpatient care, half the former heroin users had returned to the drug. In other5 studies6 the consequence has been extremely high post-discharge death rates.
Guidance7 for England stresses the need for aftercare following residential rehabilitation and continued treatment following detoxification. Arrangements are often complicated by the fact that residents return to their home areas, beyond the reach of direct aftercare provision by the initial service. However, the principles behind the featured intervention could be applied in the home area. Most services do make some arrangements, but in a survey8 4 in 10 residents were at best unclear who was to coordinate their aftercare, and care plans appeared to rely on mutual aid groups for ongoing support. Valuable as they are, arranging and monitoring attendance and responding to missed meetings is less feasible than with formal aftercare arrangements.
