Hepp, U; Moergeli, H; Buchi, S; Bruchhaus-Steinert, H; Kraemer, B; Sensky, T; Schnyder, U (2008). Post-traumatic stress disorder in serious accidental injury: 3-year follow-up study. British Journal of Psychiatry, 192(5):376-383.

Abstract

BACKGROUND: Long-term data on post-traumatic stress disorder (PTSD) following accidents are scarce. AIMS: To assess and predict PTSD in people 3 years after severe accidental injury. METHOD: Severely injured patients were recruited consecutively from the intensive care unit (n=121) and assessed within 1 month of the trauma. Follow-up interviews were conducted 6 months, 12 months and 36 months later; 90 patients participated in all four interviews. Symptoms were assessed using the Clinician-Administered PTSD Scale. RESULTS: Post-traumatic stress disorder was diagnosed in 6% of patients 2 weeks after the accident, in 2% after 1 year and in 4% after 3 years. Robust predictors of later PTSD symptom level were intrusive symptoms shortly after the accident and biographical risk factors. There were individual changes over time between the categories PTSD, sub-threshold PTSD and no PTSD. Whereas PTSD symptom severity was low or decreased for most of the patients, some of them showed an increase or a delayed onset. Patients with persisting PTSD symptoms at 6 months and patients with delayed onset of symptoms are at risk of long-term PTSD. CONCLUSIONS: The prevalence of PTSD was low over the whole period of 3 years.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
