In the multi-site Prescription Opioid Addiction Treatment Study (POATS, CTN-0030), conducted within the National Drug Abuse Treatment Clinical Trials Network (CTN), participants randomly assigned to receive individual drug counseling in addition to buprenorphine-naloxone and medical management did not have superior opioid use outcomes. However, research with other substance dependent populations shows that subgroups of participants may benefit from a treatment even if the population as a whole did not. This study reexamined data from POATS to determine whether a subgroup of participants benefited from drug counseling in addition to buprenorphine-naloxone and medical management, either due to greater problem severity or more exposure to counseling as a result of greater treatment adherence. Problem severity was measured by a history of heroin use, higher Addiction Severity Index drug composite score, and chronic pain. Adequate treatment adherence was defined a priori as attending at least 60% of all offered sessions.
Results found that participants who had used heroin at some point in their lives and who received drug counseling were more likely to be successful (i.e., abstinent or nearly abstinent from opioids) compared to heroin users who received medical management alone, but only if they were adherent to treatment and thus received adequate exposure to counseling. Adherence and thus adequate exposure to counseling did not correlate with better outcomes in non-heroin users, and the association between severity and outcome did not vary by treatment condition for chronic pain or ASI drug severity score.
Conclusions: To the extent that a history of heroin use can be considered to be a marker of severity among patients (by virtue of its correlation with poor outcome overall), the results of this study support previous research suggesting that more severe drug dependent patients respond better to more intensive forms of treatment. However, merely being offered counseling was not sufficient to produce successful outcomes for the heroin users -- these participants had to attend counseling sessions regularly in order to achieve outcomes similar to those of non-heroin users. These findings emphasize the importance of treatment adherence, and suggest that patients with prescription opioid dependence are a heterogeneous group, with different optimal treatment strategies for different subgroups.
