Depression in general practice

Area of Science:

• Psychiatry
• Primary Care Medicine
• Epidemiology

Background:

• Depression is a prevalent mental health condition often underdiagnosed in primary care settings.
• Early identification and treatment are crucial for managing depressive disorders and improving patient outcomes.

Purpose of the Study:

• To determine the prevalence of major and minor depression in a multi-ethnic primary care population.
• To investigate factors associated with depression, including socio-demographic characteristics, lifestyle, health status, and medication use.
• To assess the current recognition and treatment rates of depression in primary care.

Main Methods:

• A two-stage screening questionnaire based on Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria for major depression was employed.
• The Primary Care Evaluation of Mental Disorders (PRIME-MD) tool was used for mental disorder assessment.
• A patient questionnaire (PQ) collected data on socio-demographics, lifestyle, health, and medication use from 470 adult patients.

Main Results:

• 18.1% of patients met the criteria for major depression, and 12.1% for minor depression.
• Only 21.2% of patients with major depression were receiving antidepressant medication.
• Comorbidity was significantly higher in depressed patients compared to non-depressed individuals.

Conclusions:

• Depression is highly prevalent in primary care, yet frequently under-recognized and undertreated.
• Implementing DSM-IV criteria in routine clinical practice can enhance the detection and management of depressive disorders.
• Improved strategies are needed to address the gap in recognition and treatment of depression in primary care settings.
