Awareness under anesthesia and the development of posttraumatic stress disorder.
Failure of general anesthesia to render a patient insensate, termed "awareness," is estimated to affect between 40,000 and 140,000 patients in the US each year. This study investigated the occurrence of post-traumatic stress disorder (PTSD) in subjects who reported a past episode of intraoperative awareness. We inquired about intraoperative and postoperative experiences and studied the relationship between various surgical experiences and currently meeting the diagnosis of PTSD. ⋯ Perioperative dissociative experiences predicted having current PTSD. Being conscious during surgery is a traumatic event that may result in developing chronic PTSD. Further studies should include prospective designs of prevalence and long-term psychological, social, and overall health effects, and ways of preventing and treating awareness-induced PTSD.

Mindfulness-based stress reduction and health-related quality of life in a heterogeneous patient population.
This study examined the effects of mindfulness-based stress reduction (MBSR) on health-related quality of life and physical and psychological symptomatology in a heterogeneous patient population. Patients (n=136) participated in an 8-week MBSR program and were required to practice 20 min of meditation daily. Pre- and post-intervention data were collected by using the Short-Form Health Survey (SF-36), Medical Symptom Checklist (MSCL) and Symptom Checklist-90 Revised (SCL-90-R). ⋯ Decreased psychological distress was indicated on the SCL-90-R by a 38% reduction on the Global Severity Index, a 44% reduction on the anxiety subscale, and a 34% reduction on the depression subscale (all P<.0001). One-year follow-up revealed maintenance of initial improvements on several outcome parameters. We conclude that a group mindfulness meditation training program can enhance functional status and well-being and reduce physical symptoms and psychological distress in a heterogeneous patient population and that the intervention may have long-term beneficial effects.

ReviewRethinking practitioner roles in chronic illness: the specialist, primary care physician, and the practice nurse.
In this article, we describe an evidence-based stepped care approach to improving the care of chronic illness in organized health care systems. We review the common principles that have been found to improve the management and outcomes of patients with major depression, asthma, diabetes, and congestive heart failure. These population-based methods to improve care of chronic illness require reorganizing the roles of specialists, primary care physicians, and nurses.

Comparative StudyThe relationship between cognitive performance and employment and health status in long-term survivors of the acute respiratory distress syndrome: results of an exploratory study.
Survivors of acute respiratory distress syndrome (ARDS) are at risk for long-lasting cognitive decline due to hypoxemia, sepsis and/or psychological sequelae associated with aggressive supportive care in the intensive care unit (ICU). We conducted an exploratory study to assess cognitive performance in long-term survivors of ARDS and to investigate how cognitive functioning is related to employment status and health-related quality of life (HRQOL). At median time of 6.0 years after ICU discharge, forty-six ARDS survivors were tested with SKT, a short cognitive performance test for assessing deficits of memory and attention. ⋯ Patients with cognitive deficits described the lowest HRQOL with major limitations in the domains role-physical and social functioning when compared to patients without cognitive impairments. In conclusion, long-term ARDS survivors exhibit impaired health status and the presence of cognitive deficits is associated with disability and considerable impairments in HRQOL. More detailed psychiatric research is required to establish the etiology of these cognitive impairments.

The objective of this article was to estimate the incidence of delirium in a sample of patients undergoing elective surgery and to identify the preoperative factors most closely associated with developing this complication. Consecutive patients (n=500) underwent a full preoperative medical evaluation including assessment of cognitive and functional status. Daily evaluation on postoperative days 1 through 4 included medical record review and direct standardized patient interviews. ⋯ Patients' perceptions that alcohol had affected their health (OR=6.53 [1.58 to 28.1]) and use of narcotic analgesics just prior to admission (OR=2.7 [1.37 to 5.3]) were also significantly associated with delirium postoperatively. Several easily obtained preoperative clinical factors can be used to identify patients at risk for postoperative delirium. This approach, when combined with specialized delirium teams using established guidelines, may be more effective in targeting patients at risk, thus reducing the number of episodes and days of delirium.
