Table 1.Characteristics of patients interviewed by the BHL
All patients are categorized into one of 4 categories of severity based on the completed interview. Differences between severity groups are presented in Table 2.
Objectives: The purpose of this project was to assess the utility and feasibility of a telephone based systematic clinical assessment service, the Behavioral Health Laboratory (BHL), in the context of primary care for patients with alcohol misuse. The BHL is a service that provides Primary Care Providers (PCPs) with a summary of mental health and substance abuse (MH/SA) symptoms and provides treatment recommendations, including triage to specialty MH/SA services.
Methods: Results from AUDIT C screening of primary care patients were extracted during a period of 4 months. Descriptive results of the 94 BHL evaluations conducted during this time were available as well as information about treatment engagement.
Results: Results demonstrate both the severity of problems but also the type of provider are important determinants of referral to the BHL. Referral for further assessment is low with an overall rate of 13% for those screening positive. This compares to approximately 60% referral rate for depression. However, the BHL was successful in assessing 78.9% of those referred and comorbidity was quite common among all referrals. While rates of engagement in care are low Telephone Care Management showed promise in engaging patients in treatment.
Conclusions: The BHL offers a practical, low cost method of assessment, monitoring, and treatment planning for patients, identified in primary care, with MH/SA needs. Referral patterns for alcohol use appear very different than for depression suggesting significantly greater barriers to accessing alcohol care than depression care. Telephone monitoring and brief interventions appear effective in engaging patients in care.

Routine screening for alcohol misuse in primary care settings is an important mechanism for reducing morbidity and mortality. Alcohol misuse includes a spectrum that ranges from risky drinking to alcohol dependence and has a well-demonstrated association with disability, increased health care utilization, and mortality.
Since the prevalence of alcohol misuse is significantly higher among patients visiting a primary care practitioner than among the general population, primary care clinicians have the opportunity to play a key role in detecting alcohol misuse and in initiating prevention or treatment efforts. However, approximately half of primary care physicians rely only on clinical impressions to identify misuse. Therefore, many patients with alcohol misuse go unrecognized.
Past research has shown that brief interventions within a primary care setting are effective in treating alcohol misuse, leading to sustained reductions in alcohol use, health care utilization, and alcohol related problems.
The Behavioral Health Laboratory was developed as a clinical service to assist with providing comprehensive assessments for patients either by their clinician, or identified during routine care as potentially in need of mental health care. The BHL conducts all tests by telephone when ordered by the Primary care providers and sends test results back to PCPs together with guidelines for their interpretation and recommendations to assist in clinical decision-making.
The purpose of this service was to implement a cost effective model that would substantially increase the feasibility of providing further evaluations and triage to the majority of patients referred to this service.
Screening and Clinical Referral:
Using a logistic regression model, we explored the likelihood of referring patients who screened positive for alcohol misuse to the BHL for the variables of total score and if the clinician was an MD or not. For every one point increase in total Audit-C score, the clinicians were 1.36 times more likely to refer to the BHL (p<.001) (Figure 1). If the clinician was an MD, the clinician was 3.62 times more likely to refer to the BHL than if the clinician were not an MD (p<.001) (Figure 2).
Figure 1.Screening and Clinical Referral by provider type.*
Based on the telephone assessment, 56.4% of those referred required additional evaluation in the MH/SA clinic. Of the 58 patients, 5 refused an appointment. Of the 53 patients given an appointment, 52.8 % attended a visit in the clinic within 3 months.
Of the 20 patients enrolled in Care Management, 70% (n=14) engaged in outpatient care, 45% (n=9) attended two appointments, and 40% (n=8) attended three or more appointments.
Of those with who were eligible for a VA sponsored research study, Telephone Disease Management for At-Risk Drinking (n=8), 4 agreed to participation. This study is based on brief alcohol intervention literature and aims at reducing alcohol use or engaging patients in more formal treatment.
*Values represent means (standard deviations) for continuous measures and percentages for categorical measures.
Within the timeframe between August 1, 2004-October 31, 2004, of the 906 patients who screened positive for alcohol misuse,118 patients were referred to the BHL. Of those 118 patients that were referred to the BHL, 78.9% completed the assessment, 5.9% refused and 14.4% were unable to contact. For the 118 referred to the BHL, the mean age was 54.19 (12.46), 12.7% were over 65, and 98.3% were male (Table 1).
Costs of Assessments:
Considering cost of staffing, laboratory maintenance, administrative expenses, and program level expenses, the total cost of the BHL per assessment is approximately $45.26 per initial assessment and $25.13 per follow-up assessments.
