Introduction: Patients recovering from critical illness have been shown to be at risk of developing Post Traumatic Stress disorder (PTSD). This study was to evaluate whether a prospectively collected diary of a patient's intensive care unit (ICU) stay when used during convalescence following critical illness will reduce the development of new onset PTSD. Methods: Intensive care patients with an ICU stay of more than 72 hours were recruited to a randomised controlled trial examining the effect of a diary outlining the details of the patients ICU stay on the development of acute PTSD. The intervention patients received their ICU diary at 1 month following critical care discharge and the final assessment of the development of acute PTSD was made at 3 months. Results: 352 patients were randomised to the study at 1 month. The incidence of new cases of PTSD was reduced in the intervention group compared to the control patients (5% versus 13%, P = 0.02). Conclusions: The provision of an ICU diary is effective in aiding psychological recovery and reducing the incidence of new PTSD. Trial registration: NCT00912613.

Introduction: We wished to obtain the experiences felt by patients during their ICU stay using an original questionnaire and to correlate the memories of those experiences with health-related quality of life (HR-QOL). Methods: We conducted a prospective study in 10 Portuguese intensive care units (ICUs). Six months after ICU discharge, an original questionnaire on experiences of patients during their ICU stay, the recollection questionnaire, was delivered. HR-QOL was evaluated simultaneously, with the EQ-5D questionnaire. Between 1 September 2002 and 31 March 2003 1433 adult patients were admitted. ICU and hospital mortalities were 21% and 28%, respectively. Six months after ICU discharge, 464 patients completed the recollection questionnaire. Results: Thirty-eight percent of the patients stated they did not remember any moment of their ICU stay. The ICU environment was described as friendly and calm by 93% of the patients. Sleep was described as being good and enough by 73%. The experiences reported as being more stressful were tracheal tube aspiration (81%), nose tube (75%), family worries (71%) and pain (64%). Of respondents, 51% experienced dreams and nightmares during their ICU stay; of these, 14% stated that those dreams and nightmares disturb their present daily life and they exhibit a worse HR-QOL. Forty-one percent of patients reported current sleep disturbances, 38% difficulties in concentrating in current daily activities and 36% difficulties in remembering recent events. More than half of the patients reported more fatigue than before the ICU stay. Multiple and linear regression analysis showed that older age, longer ICU stay, higher Simplified Acute Physiology Score II, non-scheduled surgery and multiple trauma diagnostic categories, present sleep disturbances, daily disturbances by dreams and nightmares, difficulties in concentrating and difficulties in remembering recent events were independent predictors of worse HR-QOL. Multicollinearity analysis showed that, with the exception of the correlation between admission diagnostic categories and length of ICU stay (0.47), all other correlations between the independent variables and coefficient estimates included in the regression models were weak (below 0.30). Conclusion: This study suggests that neuropsychological consequences of critical illness, in particular the recollection of ICU experiences, may influence subsequent HR-QOL.

To assess the factual and delusional memories reported by intensive care unit survivors and its relationship with the development of Posttraumatic Stress Syndrome (PTSS). Multicenter observational cohort study. Nine Portuguese intensive care units, as part of a multicenter study. Between January and June 2005, 1,174 patients were admitted across the nine intensive care units. Two hundred thirty-nine patients were excluded, 14 with 49, indicating a higher risk of developing posttraumatic stress disorder. A PTSS-14 score >49 was significantly associated with not remembering the hospital stay before intensive care unit admission. Amnesia for the early period of critical illness (early amnesia) was positively associated with the level of posttraumatic stress disorder-related symptoms, which may be a proxy for severity of disease at the time of intensive care unit admission.

Objective. To evaluate health-related quality of life (HR-QOL) and study its determinants in adult patients discharged from an intensive care unit (ICU). Design. Cohort study. Setting. Intensive care unit (ICU), tertiary care hospital, Oporto, Portugal. Patients. Of all the patients discharged over a 2year period, 355 were considered eligible and 275 completed the study. Measurements and results. Patients were interviewed 6 months after ICU discharge using EuroQol 5-D (EQ-5D). At the interview only 29% reported feeling worse than 6 months before ICU admission. The proportions of those reporting moderate to extreme problems in the five dimensions studied were as follows: mobility (37%), self-care (22%), usual activities (46%), pain/discomfort (45%) and anxiety/depression (54%). Although 77% of patients reported a problem in at least one dimension, 44% referred to no problems or only moderate problems regarding pain or anxiety. EQ visual analogue scale (VAS) and EQ Index medians were 60 and 81, respectively. Conclusions. Intensive care unit variables (e.g., diagnosis, length of stay and severity of disease) and patient's background data (e.g., age, gender, education, main activity, smoking habits, experience with serious illness and previous health status) may be significant determinants of HR-QOL. However, when adjusted for background data, most ICU variables are no longer associated with EQ-5D. This should cause attention to be paid to the role of a patient's background in the evaluation of HR-QOL and to a careful interpretation of EQ-5D results when comparing ICUs.
