Problem substance use among depressed patients in managed primary care

Area of Science:

• Psychiatry
• Primary Care Medicine
• Addiction Research

Background:

• Depression is common in primary care, often co-occurring with substance use disorders.
• Understanding these co-occurring conditions is crucial for effective patient management.
• Primary care settings are vital for early identification and intervention.

Purpose of the Study:

• To identify demographic and clinical characteristics associated with problem substance use in primary care patients with depressive symptoms or disorders.
• To differentiate characteristics linked to specific substance use issues (sedative misuse, cannabis use, hazardous drinking).

Main Methods:

• Cross-sectional study of 1,187 patients from primary care clinics within six managed care organizations.
• Data collected on depressive symptoms/disorders and patterns of substance use (sedative misuse, cannabis, alcohol).
• Statistical analysis to identify associations between patient characteristics and substance use problems.

Main Results:

• Sedative misuse (14%) linked to higher socioeconomic status, social phobia, and prescription opioid misuse.
• Cannabis use (11%) associated with younger age, male gender, single status, white ethnicity, lower education, recurrent depression, agoraphobia, and hazardous alcohol use.
• Hazardous drinking (11%) associated with younger age, male gender, single status, and cannabis use.

Conclusions:

• Problem substance use is prevalent in primary care patients with depression.
• Distinct characteristics are associated with different types of substance use, informing targeted screening.
• Improved understanding can enhance early identification and service provision for this vulnerable population.
