Loma Linda Researchers Find Rate of PTSD-related Hospitalizations Nearly Doubled from 2002-2011 for Young Women

Researchers at the Loma Linda University Schools of Medicine and Public Health found that cases of Post Traumatic Stress Disorder (PTSD) hospitalizations rose substantially in a 10-year span. The researchers used data from the Nationwide Inpatient Sample (NIS), the largest all-payer civilian inpatient database in the United States.

Dr. Jim E. Banta,  associate professor in the LLU School of Public Health notes, “NIS includes patients covered by Medicare, Medicaid, private insurance and those without insurance. Our paper shows that for the 10 calendar years following September 11, 2001, the rate of PTSD-related hospitalizations increased for all age and gender groups; but nearly doubled for young women aged 20-44, jumping from 74 to 139 hospitalizations per 100,000 in the Census population. Moreover, most of these women were hospitalized with other mental conditions such as mood, substance use, and personality disorders.”

Lead author Dr. Mark G. Haviland, professor of psychiatry in the LLU School of Medicine noted, “These data underscore the prevalence, severity, and complexity of PTSD in the general population. Assessment and treatment protocols must address the underlying stressors, which lead to various medical and mental/substance abuse disorders. Prevention efforts and early diagnosis are as critical as treatment initiatives.”

Co-authors were Dr. Peter Przekop, from the LLU School of Medicine and the Betty Ford Center, and Dr. Janet L. Sonne, from the LLU Behavioral Health Center and the LLU School of Behavioral Health. The paper, Posttraumatic Stress Disorder–Related Hospitalizations in the United States (2002–2011): Rates, Co-Occurring Illnesses, Suicidal Ideation/Self-Harm, and Hospital Charges, was released online ahead of publication in The Journal of Nervous and Mental Disease, available at:
