Traumatic life events in primary care patients: a study in an ethnically diverse sample

Area of Science:

• Public Health
• Psychiatry
• Health Services Research

Background:

• Traumatic life events (TLEs) are prevalent in primary care settings.
• Understanding TLEs' impact on mental health and healthcare utilization is crucial for diverse patient populations.

Purpose of the Study:

• To determine the prevalence, types, and predictors of TLEs among primary care patients.
• To investigate the relationship between TLEs, psychiatric disorders, and primary care service utilization.

Main Methods:

• A survey with a structured diagnostic interview was conducted.
• 1,456 adult patients from diverse ethnic backgrounds in a Southern California primary care clinic participated.
• Data collected included TLEs, psychiatric diagnoses (DSM-III criteria), physical functioning, and clinic visit frequency.

Main Results:

• Nearly 10% of patients experienced a TLE in the past year; 57% experienced at least one in their lifetime.
• Interpersonal violence, acute loss/accidents, witnessing death, and domestic violence were common TLEs.
• Central American immigrants reported higher TLE rates than US-born non-Latino whites; marital status was a predictor.
• TLEs, female gender, and non-Latino ethnicity were associated with psychiatric disorders.
• Psychiatric disorders correlated with poorer physical functioning and increased clinic visits.

Conclusions:

• TLEs are common in ethnically diverse primary care patients and linked to psychiatric disorders beyond PTSD.
• Psychiatric disorders significantly impact physical health and increase primary care utilization.
• Integrating trauma screening into psychiatric assessments is essential for effective patient care.
