Continuity of care and clinical effectiveness: outcomes following residential treatment for severe substance abuse.
BACKGROUND
Continuity of care (COC) has often been viewed as a crucial indicator of treatment quality for patients with severe psychiatric or addictive disorders. However, the relationship between COC and clinical outcomes has received little empirical evaluation.


METHODS
This study used hierarchical linear modeling to examine the relationship between six indicators of COC and seven outcome measures addressing symptoms, substance abuse, and social functioning.


METHODS
Patient interviews were conducted with 1576 veterans 3 months after their discharge from one of 22 residential work therapy programs for the treatment of severe substance abuse.


RESULTS
Few significant relationships were found between COC and outcome measures in analyses conducted at both the client and program level and fewer than half of these show better outcomes with greater COC. When a Bonferroni corrected P level of P <0.0012 was used, none of the relationships were statistically significant.


CONCLUSIONS
Although there were significant relationships between outcomes and measures of services received during residential treatment, postdischarge COC does not seem to be related to improved outcomes, at least when examined following long term intensive residential treatment. Thus, our results are specific to the context of aftercare following long-term residential rehabilitation and indicate that the value of standard performance measures may vary by treatment context.
