Preburn psychiatric history affects posttrauma morbidity

Area of Science:

• Psychiatry
• Trauma Studies
• Burn Injury Research

Background:

• Burn injuries are severe physical traumas with potential long-term psychological consequences.
• Understanding the psychiatric comorbidity in burn survivors is crucial for effective treatment and recovery.
• Previous research has indicated a link between trauma and mental health disorders, but specific data on burn populations require further investigation.

Purpose of the Study:

• To determine the prevalence of psychiatric disorders in adult burn survivors.
• To compare the lifetime and 12-month postburn disorder prevalence in burn survivors versus the general population.
• To identify risk factors for developing psychiatric disorders, including posttraumatic stress disorder (PTSD), after a burn injury.

Main Methods:

• A cohort of 95 inpatient, burn-injured adults was assessed at discharge, 4 months, and 12 months post-injury.
• Structured interviews and DSM-III-R criteria were used for diagnosis.
• Data were compared with the National Comorbidity Study's national community-dwelling comparison group.

Main Results:

• Burn survivors exhibited significantly higher lifetime prevalence of affective, alcohol, and substance use disorders compared to the general population.
• Lifetime anxiety disorders were less prevalent in burn survivors.
• The 12-month postburn prevalence of alcohol and substance use disorders was significantly elevated in burn survivors.
• A history of preburn affective, alcohol, or substance use disorder increased the risk for postburn disorders.
• Preburn affective disorder elevated the risk for developing posttraumatic stress disorder (PTSD), while preburn anxiety disorder did not.
• Postburn PTSD correlated with a longer hospital stay, and preburn comorbidity predicted employment status and hospitalization length.

Conclusions:

• Burn survivors face a higher burden of psychiatric disorders, particularly affective, alcohol, and substance use disorders, both in lifetime prevalence and in the year following injury.
• Pre-existing mental health conditions are significant predictors of developing psychiatric disorders post-burn, including PTSD.
• These findings underscore the need for comprehensive psychiatric screening and management in burn care to address the elevated risk and long-term impact of these disorders.
