[PTSD in somatic disease].

This review describes the incidence of posttraumatic stress disorder (PTSD) in physically ill patients. At the beginning, research in the field of PTSD was primarily focused on war veterans and victims of bodily assault or rape. Starting in the early 90 s, PTSD after civilian traumas such as motor vehicle accidents was diagnosed increasingly more often. Recent publications showed that PTSD can also follow serious somatic diseases. Hence, awareness during anaesthesia, prolonged ICU treatment (ARDS, septic shock), burns, successful resuscitation after cardiac arrest, coronary artery bypass surgery, organ transplantation and cancer were all linked to the development of PTSD. Prevalence of PTSD in these medical conditions lies around 5 - 10 %, and it is therefore considered an important comorbidity. Unfortunately, the diagnosis and treatment of PTSD are not well enough established yet and thus do receive too little attention in the treatment regime of somatic illness. Generally, PTSD can occur with every life-threatening disease, but possibly also with less severe diseases if the patient experiences intense fear. PTSD symptoms, especially intrusive recollections, avoidance and hyper-arousal can impair the patients' quality of life more than the primary disease. This seems to be also true for sub-syndromal PTSD. To adequately diagnose and treat patients at risk of developing PTSD, close collaboration between physicians of all subspecialties and psychiatrists will be necessary.

Pulmonary function and health-related quality of life in a sample of long-term survivors of the acute respiratory distress syndrome.

OBJECTIVE: We performed a follow-up cohort analysis in order to delineate the correlation between pulmonary function (PF) and health-related quality of life (HRQL) in patients after ARDS. DESIGN: Follow-up cohort study. SETTING: A 20-bed ICU of a university teaching hospital. PATIENTS: A cohort of 50 long-term survivors of ARDS. MEASUREMENTS AND RESULTS: Measurements of PF (FVC, FEV1, TLC, D(LCO)) and HRQL (SF-36 Health Status Questionnaire) were made 5.5 years (median value) after discharge from the ICU. Impairments in PF (defined as PF results below 80% of the predicted value) were frequent but generally mild. Twenty patients had a single PF impairment (with limitations in FEV1/FVC ratio in 12 patients being the most common), four patients had two (with D(LCO) and FEV1/FVC ratio impairment the most common) and three patients had pathologic results in three PF tests (FEV1/FVC ratio, TLC and capillary pO2 during exercise in one case, FVC, TLC and capillary pO2 during exercise in the second patient and FVC, TLC and D(LCO) in the third). Compared to normal controls, survivors of ARDS showed impairments in all SF-36 health dimensions (p < 0.001). Patients with multiple (> 1) PF impairments described the lowest HRQL with major limitations in all SF-36 categories (p < 0.037) including physical and mental summary scores (36.5 vs 46.9, p = 0.037 and 31.3 vs 51.4, p = 0.003) when compared to patients with no or only one PF impairment. CONCLUSIONS: Long-term survivors of ARDS have a significant reduction in HRQL and the presence of multiple PF impairments is associated with maximal decrements in HRQL.

Sensitivity and specificity of a screening test to document traumatic experiences and to diagnose post-traumatic stress disorder in ARDS patients after intensive care treatment.

OBJECTIVE: Many survivors of critical illness and intensive care unit (ICU) treatment have traumatic memories such as nightmares, panic or pain which can be associated with the development of posttraumatic stress disorder (PTSD). In order to simplify the rapid and early detection of PTSD in such patients, we modified an existing questionnaire for diagnosis of PTSD and validated the instrument in a cohort of ARDS patients after long-term ICU therapy. DESIGN: Follow-up cohort study. SETTING: The 20-bed ICU of a university teaching hospital. PATIENTS: A cohort of 52 long-term survivors of the acute respiratory distress syndrome (ARDS). INTERVENTIONS AND MEASUREMENTS: The questionnaire was administered to the study cohort at two time points 2 years apart. At the second evaluation, the patients underwent a structured interview with two trained psychiatrists to diagnose PTSD according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria. The reliability and validity of the questionnaire was then estimated and its specificity, sensitivity and optimal decision threshold determined using receiver operating characteristic (ROC) curve analyses. RESULTS: The questionnaire showed a high internal consistency (Crohnbach's alpha = 0.93) and a high test-retest reliability (intraclass correlation coefficient alpha = 0.89). There was evidence of construct validity by a linear relationship between scores and the number of traumatic memories from the ICU the patients described (Spearman's rho = 0.48, p < 0.01). Criterion validity was demonstrated by ROC curve analyses resulting in a sensitivity of 77.0% and a specificity of 97.5% for the diagnosis of PTSD. CONCLUSIONS: The questionnaire was found to be a responsive, valid and reliable instrument to screen survivors of intensive care for PTSD.

The effect of stress doses of hydrocortisone during septic shock on posttraumatic stress disorder and health-related quality of life in survivors.

OBJECTIVES: The exposure to intense physical and psychological stress during intensive care can result in posttraumatic stress disorder (PTSD) in survivors. Cortisol is a biological stress mediator that can have a protective effect during severe stress. The administration of stress doses of hydrocortisone during treatment in the intensive care unit could theoretically result in a lower incidence of PTSD. We tested this hypothesis in survivors of septic shock. DESIGN: A retrospective case-controlled analysis. SETTING: A 20-bed multidisciplinary intensive care unit of a tertiary-care university hospital. PATIENTS: We identified 27 patients who received standard therapy for septic shock. These patients served as controls and were compared with an equal number of patients who received hydrocortisone in addition to standard treatment. These patients were selected from our database with regard to age (+/-4 yrs), gender, and cause of septic shock to be as similar as possible with control patients. INTERVENTIONS: Patients from the hydrocortisone group had received stress doses of hydrocortisone (100 mg bolus, followed by 0.18 mg/kg/hr) in addition to standard treatment. Patients from the control group received standard protocol-driven treatment only. PTSD was diagnosed with the Posttraumatic Stress Syndrome-10 inventory, a self-report scale for diagnosis of PTSD. Health-related quality of life was measured using the Medical Outcomes Study Short-Form Survey (Medical Outcomes Trust, Boston, MA), which consists of 36 questions. MEASUREMENTS AND MAIN RESULTS: Patients who received hydrocortisone during septic shock had a significantly lower incidence of PTSD than patients who received standard treatment only (5 of 27 vs. 16 of 27; p = .01) and had significantly higher scores on the mental health index of the Medical Outcomes Study Short-Form health-related quality-of-life questionnaire (68 vs. 44 points; p = .009). CONCLUSIONS: Data from this study support the hypothesis that the administration of stress doses of hydrocortisone in doses equivalent to the maximal endocrine secretion rate during septic shock reduces the incidence of PTSD and improves emotional well-being in survivors. This hypothesis should be tested in a prospective randomized trial.
