Alcohol use and abuse is common in primary care practices

Very little research has focused on illicit substance use disorders in the context of primary care

BHL is designed to provide clinical services to support providers in Primary Care and Behavioral Health

It is intended to be analogous to Clinical Chemistry or Radiology Laboratories

The BHL is an automated telephone assessment, triage, and monitoring service for patients identified by primary care providers as having depressive symptoms or at-risk drinking.

The BHL conducts a brief telephone (20-30 minutes) assessment generating a report for the PCP including diagnosis, severity, and general treatment recommendations.

How it works at the PVAMCHow it works at the PVAMC

Mechanisms for requesting an assessment Screening Referral Disease management

The BHL receives a printed consult request.

The BHL reports findings, provides interpretation, and recommendations.

Where appropriate, BHL staff facilitate referral or the appropriate level of intervention.

What does the Service Provide?What does the Service Provide?

ConclusionsConclusions

BHL is a flexible, evidence based program Fills gaps in the VHA system Provides valid information and documentation

Acceptable to veterans Valued by provider

Can function at low cost across diverse settings Useful for outreach Can provide coordination as well as assessment

Disease Management Referral Management

Valuable as a tool for improving system performance
