AbstractBackground:To date, little research has been published on the prominence of the various psychiatric symptoms that result from exposure to a natural disaster. In our study of stress-related symptoms among Norwegian tourists who were repatriated after the 2004 southeast Asian tsunami, we evaluated to what extent symptom scores differed between individuals who were exposed to the disaster and those who were not. Methods:Participants (n = 899) completed a questionnaire via post 6 months after the disaster. The participants were categorized according to their level of exposure to the disaster: danger exposed (caught or chased by the waves), nondanger exposed (other disaster-related stressors) and not exposed. Symptoms were assessed by the General Health Questionnaire (GHQ-28), the Post Traumatic Symptom Scale (PTSS-10), and the Impact of Event Scale – Revised (IES-R). We used z-transformation of symptom scores (Z-scores) to evaluate the extent to which symptom scores among disaster-exposed individuals differed from those in the nonexposed reference group. Results:The IES-R revealed the greatest differences between nonexposed and disaster-exposed individuals. Hyperarousal was the most prominent symptom cluster that related to disaster exposure, followed by intrusion and then avoidance. Symptoms of anxiety, social dysfunction, withdrawal, somatization and feelings of guilt were more closely linked to exposure than were symptoms of depression. Conclusions:Our results indicate that symptoms of hyperarousal may be more closely linked to acute exposure to a natural disaster such as a tsunami than other symptoms of psychological distress.Copyright © 2009 S.

: Background To evaluate hospital-acquired infections (HAIs) in somatic (all admissions other than psychiatric) and psychiatric patients admitted to a tertiary university hospital in Oslo, before and after reorganization of the Norwegian healthcare system in 2002. : Methods Point prevalence studies were conducted four times per annum and over the period from 1995 to 2007. : Results A total of 57 360 patients were studied over the whole time period: 80.5% in somatic wards and 19.5% in psychiatric wards. The HAI rate was 6.9%, of which 8.1% were somatic and 1.9% psychiatric. 13.4% of operated patients had HAI, including 6.2% due to surgical wound infections. In somatic wards, 0.6–1% were re-admitted with HAI, 15.2–23% had infections and 18–23% used antibiotics. There was a reduction in HAI until 2002. From 2003 on, HAI increased (P = 0.010) in somatic wards (P = 0.002), in non-operated patients (P = 0.024) and in extra costs. In 2002, the Norwegian healthcare system was reorganized. This reorganization led to a 30% increase in somatic patients treated from 2003 to 2007 (P = 0.054), 27% increase in the total workload per work position (P = 0.024) and 23.5% decrease in internal service work. : Conclusion A declining trend of HAI was observed from 1995 to 2002 at the tertiary university hospital in Norway. In 2002, the Norwegian healthcare system was reorganized. From 2003 to 2007, HAI increased significantly as did the number of somatic patients and workload at our hospital. [ABSTRACT FROM AUTHOR]
