Abstract [en]

OBJECTIVE: It is common for persons with psychiatric disorders to also have alcohol problems. Studies in the general population as well as in clinical samples have found hazardous or harmful alcohol habits to be particularly prevalent in the presence of psychiatric disorders. This study sought to explore the relationships between drinking habits and health care utilization (psychiatric as well as general medical) in persons seeking psychiatric treatment and to investigate the associations among age, sex, and type or number of diagnoses and health care use and costs. For the planning of targeted interventions, we also sought to identify subgroups with a high prevalence of hazardous drinking habits.

METHODS: From a psychiatric clinic for affective disorders at a university hospital in Sweden, patients who had been screened for hazardous drinking (N = 609) were selected. Patients with primary psychosis or substance use disorder receive treatment at other clinics and did not participate. Medical records data were grouped and compared. The International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) was used for diagnoses and the Alcohol Use Disorders Identification Test for screening. Patients were grouped by drinking habits and sex, age, and diagnosis group, and their psychiatric as well as general medical health care use was compared.

RESULTS: Abstainers used psychiatric care more than all other drinking groups (p < .001). Psychiatric health care costs were higher in abstainers and low-risk drinkers (1.64 to 1). No differences in general medical care could be identified between drinking groups. Specific subgroups with higher rates of hazardous drinking could not be identified (44% of all males and 34% of all females reported such habits). Inconclusive results from previous research are most likely due to different methods used to classify drinking problems.

CONCLUSIONS: Abstainers and low-risk drinkers used psychiatric health care to a higher cost than the other drinking groups. Possible explanations are discussed from a clinical and scientific perspective. This study clarifies the need for uniform measures when classifying alcohol use in studies of relationships between alcohol use and health care use. There is also a need to separate former drinkers from abstainers in future studies.

Abstract [en]

Background : The risk of developing enduring post-traumatic stress reactions and mental health problems in the aftermath of disasters is substantial. However, there are inconsistencies regarding the contribution of physical injury as an independent risk factor for developing psychiatric morbidity after disasters.

Aims : The aim was to assess whether physical injury was associated with post-traumatic stress reactions and general mental health after adjusting for perceived life-threat in the aftermath of the 2004 tsunami.

Methods : A sample of 1501 highly exposed survivors from the 2004 Southeast Asia tsunami was selected from a cohort of Swedish survivors surveyed 14 and 36 months after the event. The impact of physical injury on post-traumatic stress and general mental health was assessed by regression models accounting for subjective life-threat.

Results : Physical injury was associated with higher levels of post-traumatic stress reactions and poorer general mental health. These associations were observed at both 14 and 36 months after the disaster.

Conclusions : Physical injury has a specific contribution to the association between traumatic experience and both post-traumatic stress reactions and general mental health in victims of the 2004 tsunami. The effect is stable over several years.

Abstract [en]


Individual factors such as gender, age, coping and personality traits and injury-related factors such as injury severity have been implicated as risk factors for poor perceived health after burns. As psychiatric morbidity is common in individuals who sustain burns, the aim of this study was to examine the effect of preinjury psychiatric problems on perceived health after injury.


A total of 85 consecutive patients treated at a national burn center were prospectively assessed: the patients were interviewed during acute care with the Structured Clinical Interview for DSM-IV Axis I Disorders. One year after injury, perceived health was assessed with the Bum-Specific Health Scale-Brief (BSHS-B). Multiple regression analyses were used to evaluate the predictive effect of preinjury psychiatric history on perceived postinjury health.


Psychiatric morbidity, especially mood disorders, affected outcome for six of the nine BSHS-B subscales, with the covariates mainly being the length of hospital stay and total burn size.


The results show that a history of preinjury psychiatric disorders, especially during the year before the burn, affects perceived outcome regarding both physical and psychological aspects of health 1 year after injury and that it is a risk factor for worse perceived outcome.

Abstract [en]

The Impact of Event Scale (IES) and the Impact of Event Scale-Revised (IES-R) are often used as self-reportinstruments for symptoms of post-traumatic stress disorder (PTSD). However, there are few validationsof the IES and the IES-R against structured clinical interviews. In this study the two scales, together withthe three subscales of the IES-R, were assessed for their agreement with a diagnosis of PTSD in patientswith burns 1 year after injury. Sixty patients with burns were evaluated 1 year after injury using theStructured Clinical Interview for the DSM-IV Axis I (SCID-I) psychiatric disorders and a Swedish versionof the IES-R. The total score of the IES-R had the best discriminant ability (0.89) with a sensitivity of 1.0and a specificity of 0.78. In conclusion, the total IES-R had good properties as a screening tool for PTSDand subsyndromal PTSD 1 year after burn injury.

Abstract [en]

Trauma-related attentional bias is suggested to play a role in maintaining posttraumatic stress disorder (PTSD). Although being burn injured is a traumatic event for many patients, there are no prospective studies investigating attentional bias. The aims were to assess burn-specific attentional bias 1 year after burn, and its associations with risk factors for PTSD and symptoms of PTSD. A total of 38 adult patients with burns were assessed with a structured clinical interview and a Swedish version of the Impact of Event Scale-Revised up to 1-year after burn. The Emotional Stroop Task was used to assess attentional bias 1 year after burn. In total 29 participants displayed burn-specific attentional bias. This group had more previous life events, perceived life threat, larger burns, and higher PTSD symptom severity. In conclusion, the majority of the patients had burn-specific attentional bias 1 year after burn and this was related to symptoms of PTSD.
