Substance abuse has been a major urban health problem, and in response, drug abuse treatment programs have been developed. Retention in programs is key to their effectiveness, yet attrition is a well recognized problem in this area. Most of the research on drug treatment programs attrition/retention rates examined individual level factors of the patients in treatment and less so provider level. Data on possible ecological or neighborhood factors relating to attrition/retention are sparse. However, such factors would seem promising to consider as neighborhood-level investigations have identified factors that influence illicit drug use. For example, a recent study reported that neighborhood disadvantage is an independent predictor of drug use, especially for individuals with lower incomes. 1 In this issue of the Journal of Urban Health, Jacobson extends conceptual thinking about contextual factors that may influence drug treatment retention 2 and undertakes the first quantitative exploration assessing Bappropriateness[ of treatment locations. 3 In the study, Jacobson identifies neighborhood-level disadvantage, violence and victimization, and drug activity as elements with likely influence on treatment attrition. To do this, he compared measures of these factors for public treatment facility locales in the city of Los Angeles with those for the residential neighborhoods of the patients enrolled in treatment. Jacobson reported that up to 20% of patients are receiving drug treatment in an area that has a greater risk profile than the place in which they reside. Still, the question remains as to whether the patients that attend treatment in more disadvantaged locations than those in which they reside have worse treatment outcomes than those whose residential locations are equivalent to or worse than their treatment locations. Further research is clearly necessary in order to more fully understand the treatment location-treatment outcome dynamic.Nonetheless, Jacobson's results can have important policy implications by renewing discussion and debate about appropriate placement for drug abuse treatment programs. On the one hand, locating drug treatment facilities in more advantaged neighborhoods has the potential for a positive impact on patient outcomes. First, fewer patients would be going to drug treatment in locations that have worse measures of neighborhood context than their current residences. Second, Jacobson finds that currently the average patient is 2.6 and 2.7 times more likely to both attend treatment in and live in a disadvantaged neighborhood than the average non-patient, respectively. Continuation of drug use is related to contextual cues; removing users from their environment would likely result in better outcomes.
