Truth and method

ContextIn the intensive care unit (ICU), delirium is a common yet underdiagnosed
form of organ dysfunction, and its contribution to patient outcomes is unclear.ObjectiveTo determine if delirium is an independent predictor of clinical outcomes,
including 6-month mortality and length of stay among ICU patients receiving
mechanical ventilation.Design, Setting, and ParticipantsProspective cohort study enrolling 275 consecutive mechanically ventilated
patients admitted to adult medical and coronary ICUs of a US university-based
medical center between February 2000 and May 2001. Patients were followed
up for development of delirium over 2158 ICU days using the Confusion Assessment
Method for the ICU and the Richmond Agitation-Sedation Scale.Main Outcome MeasuresPrimary outcomes included 6-month mortality, overall hospital length
of stay, and length of stay in the post-ICU period. Secondary outcomes were
ventilator-free days and cognitive impairment at hospital discharge.ResultsOf 275 patients, 51 (18.5%) had persistent coma and died in the hospital.
Among the remaining 224 patients, 183 (81.7%) developed delirium at some point
during the ICU stay. Baseline demographics including age, comorbidity scores,
dementia scores, activities of daily living, severity of illness, and admission
diagnoses were similar between those with and without delirium (P>.05 for all). Patients who developed delirium had higher 6-month
mortality rates (34% vs 15%, P = .03) and spent 10
days longer in the hospital than those who never developed delirium (P<.001). After adjusting for covariates (including age,
severity of illness, comorbid conditions, coma, and use of sedatives or analgesic
medications), delirium was independently associated with higher 6-month mortality
(adjusted hazard ratio [HR], 3.2; 95% confidence interval [CI], 1.4-7.7; P = .008), and longer hospital stay (adjusted HR, 2.0;
95% CI, 1.4-3.0; P<.001). Delirium in the ICU
was also independently associated with a longer post-ICU stay (adjusted HR,
1.6; 95% CI, 1.2-2.3; P = .009), fewer median days
alive and without mechanical ventilation (19 [interquartile range, 4-23] vs
24 [19-26]; adjusted P = .03), and a higher incidence
of cognitive impairment at hospital discharge (adjusted HR, 9.1; 95% CI, 2.3-35.3; P = .002).ConclusionDelirium was an independent predictor of higher 6-month mortality and
longer hospital stay even after adjusting for relevant covariates including
coma, sedatives, and analgesics in patients receiving mechanical ventilation.

The lived experiences of adult intensive care patients who were conscious during mechanical ventilation: A phenomenological-hermeneutic study

On the use of narratives in nursing research Narratives have always been a path to knowledge in nursing care but are a recent element within nursing research. Therefore, this article deals with the narrative and its use within nursing research. First, the use of narratives in nursing care and nursing research is examined. Second, Paul Ricoeur's narrative theory with its dimensions of interpretation, time, action and ethics is presented as a possible methodological basis. Third, the use of Ricoeur's narrative theory in nursing research is examined, showing that, at present, support mainly comes from Ricoeur's text interpretation theory. Finally, a nursing research approach to the narrative, based on the life-world, is suggested.

The effect of postoperative pain management program on improving nurses’ knowledge and attitudes toward pain

BACKGROUND:: To examine the relationship between delusional memories from the Intensive Care Unit (ICU) stay, health related quality of life (HRQoL), anxiety, and symptoms of depression in patients with physical trauma, 6 months to 18 months after their ICU stay. METHODS:: Multicenter study in five combined medical and surgical ICUs (n = 239). A questionnaire comprising the Medical outcome Short Form 36, the Hospital Anxiety and Depression scale, and the Intensive Care Unit Memory tool was sent to the patients with trauma 6 months to 18 months after their discharge from the ICU. Clinical data were drawn from patient records in retrospect. A matched reference sample (n = 159) was randomly drawn from the Swedish Short Form 36 norm database (n = 8,930). RESULTS:: Patients with trauma had significantly lower HRQoL than the reference sample. One or more delusional memories such as hallucinations, nightmares, dreams, or sensations of people trying to hurt them in the ICU were experienced by 26%. These patients were significantly younger, had a longer ICU stay, relied more on mechanical ventilation, and had higher Injury Severity Score and Sequential Organ Failure Assessment scores. They also reported a significantly poorer HRQoL and a higher probability of experiencing anxiety (51% vs. 29%) and symptoms of depression (48% vs. 26%) compared with patients without such memories. CONCLUSIONS:: Our results highlight the importance of treating the delusional memories experienced by ICU patients with a trauma diagnosis as a postinjury factor with a potential to create anxiety and symptoms of depression and which may affect HRQoL after discharge.
