Continuity of Care Performance Measure Not Associated with Improved Outcomes for Veterans with Substance Use Disorders


VA currently incentivizes two quality measures related to Veterans' substance use care: 1) annual alcohol misuse screening in all primary care medical settings, and 2) Continuity of Care (CoC) for Veterans in new episodes of specialty substance use disorder (SUD) treatment. The CoC performance measure specifies that patients should receive at least two SUD outpatient visits in each of the three consecutive 30-day periods after they qualify as new SUD patients. This study evaluated the link between patient outcomes and the CoC performance measure in 1,850 randomly selected Veterans from 109 SUD treatment programs at 73 VA facilities. Investigators assessed data that included demographics and medical/psychiatric comorbidities, in addition to a self-administered questionnaire focusing on Veterans' Addiction Severity Index (ASI) composite scores. Facility-level analyses also were conducted using the ASI alcohol and drug composites, as well as facility rates of meeting the CoC performance measure.

Findings show that meeting the CoC performance measure was not associated with patient-level improvements in the ASI alcohol or drug composites, days of alcohol intoxication, or days of substance-related problems. Higher facility-level rates of CoC were negatively associated with improvements in ASI alcohol and drug composites - and were not associated with follow-up abstinence rates. Overall, authors suggest that these findings indicate that researchers and quality managers will need to determine if changes in performance on new criteria are associated with changes in average patient outcomes.

What are HSR Publication Briefs?

HSR requires notification by HSR-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR published articles. Visit the HSR citations database for a complete listing of HSR articles and presentations.
