Unita' di Riabilitazione e Terapie Palliative, Department of Anesthesia and Critical Care, National Cancer Institute of Milan, Italy. BACKGROUND: The objective of this study was to evaluate the impact of delirium on the survival of advanced cancer patients also assessed with a validated prognostic score (the palliative prognostic [PaP] score). METHODS: The study population was a prospective multicenter consecutive case series of advanced cancer patients for whom chemotherapy was no longer considered viable and who were referred to palliative care programs. Clinical and biologic prognostic factors included in the PaP score were assessed at study entry. The Confusion Assessment Method criteria were applied to screen patients presenting with delirium. Survival times were measured from time of enrollment and death taken as an outcome. Survival curves were traced with the Kaplan-Meier method and comparison were based on log rank tests. RESULTS: Delirium was found in 109 cases among 393 consecutive patients (27.7%). The diagnosis of delirium was independently associated with male gender, central nervous system metastases, lower performance status, worse clinical prediction of survival, and progestational treatment. The survival curve of patients with delirium was significantly different from the nondelirious patients curve (log rank, 31.6, P < 0.0001). The median survival time was 21 days (95% confidence interval [CI], 16-27) for the delirious patients and 39 days (95% CI 33-49) for the others. Multivariate analysis showed that the diagnosis of delirium and PaP score were independently associated with prognosis. CONCLUSIONS: The diagnosis of delirium significantly worsens life expectancy prognosticated with the PaP score. By using the PaP score together with the assessment of cognitive status, physicians can correctly predict patients 30-day survival in greater than 70% of cases.

Afessa B , Morales IJ , Scanlon PD , Peters SG . Department of Internal Medicine, Division of Pulmonary and Critical Care, University of Florida Health Science Center, Jacksonville, FL, USA. afessa.bekele@mayo.edu OBJECTIVE: To describe prognostic factors, clinical course, and hospital outcome of patients with chronic obstructive pulmonary disease admitted to an intensive care unit for acute respiratory failure. DESIGN: Analysis of prospectively collected data. SETTING: A multidisciplinary intensive care unit of an inner-city university hospital. PATIENTS: Patients with chronic obstructive pulmonary disease admitted to an intensive care unit for acute respiratory failure from August 1995 through July 1998. MEASUREMENTS AND MAIN RESULTS: Data were obtained concerning demographics, arterial blood gas, Acute Physiology and Chronic Health Evaluation (APACHE) II score, sepsis, mechanical ventilation, organ failure, complications, and hospital mortality rate. Fifty-nine percent of patients were male, 63% white, and 36% African-American; the mean age was 63.1 +/- 8.9 yrs. Noninvasive mechanical ventilation was tried in 40% of patients and was successful in 54% of them. Invasive mechanical ventilation was required in 61% of the 250 admissions. Sepsis developed in 31% of patients, nonpulmonary organ failure in 20%, pneumothorax in 3%, and acute respiratory distress syndrome in 2%. Multiple organ failure developed in 31% of patients with sepsis compared with 3% without sepsis (p <.0001). Predicted and observed hospital mortality rates were 30% and 15%, respectively. Differences in age and arterial carbon dioxide and oxygen tensions between survivors and nonsurvivors were not significant. Arterial pH was lower in nonsurvivors than in survivors (7.21 vs. 7.25, p =.0408). The APACHE II-predicted mortality rate (p =.0001; odds ratio, 1.046; 95% confidence interval, 1.022-1.070) and number of organ failures (p <.0001; odds ratio, 5.524; 95% confidence interval, 3.041-10.031) were independent predictors of hospital outcome; invasive mechanical ventilation was not an independent predictor. CONCLUSIONS: Physiologic abnormalities at admission to an intensive care unit and development of nonrespiratory organ failure are important predictors of hospital outcome for critically ill patients with chronic obstructive pulmonary disease who have acute respiratory failure. Improved outcome would require prevention and appropriate treatment of sepsis and multiple organ failure.

Evidence Based Prognostication - AAHPM Annual Assembly 2007 February 14, 2007 Sinclair, Salacz, Affield Narcotic and benzodiazepine use after withdrawal of life support: association with time to death? Chan JD , Treece PD , Engelberg RA , Crowley L , Rubenfeld GD , Steinberg KP , Curtis JR . Department of Epidemiology, School of Public Health and Community Medicine, University of Washington, Seattle, USA. jdchan@u.washington.edu OBJECTIVE: To determine whether the dose of narcotics and benzodiazepines is associated with length of time from mechanical ventilation withdrawal to death in the setting of withdrawal of life-sustaining treatment in the ICU. DESIGN: Retrospective chart review. SETTING: University-affiliated, level I trauma center. PATIENTS: Consecutive critically ill patients who had mechanical ventilation withdrawn and subsequently died in the ICU during two study time periods. RESULTS: There were 75 eligible patients with a mean age of 59 years. The primary ICU admission diagnoses included intracranial hemorrhage (37%), trauma (27%), acute respiratory failure (27%), and acute renal failure (20%). Patients died during a median of 35 min (range, 1 to 890 min) after ventilator withdrawal. On average, 16.2 mg/h opiates in morphine equivalents and 7.5 mg/h benzodiazepine in lorazepam equivalents were administered during the time period starting 1 h before ventilator withdrawal and ending at death. There was no statistically significant relationship between the average hourly narcotic and benzodiazepine use during the 1-h period prior to ventilator withdrawal until death, and the time from ventilator withdrawal to death. The restriction of medication assessment in the last 2 h of life showed an inverse association between the use of benzodiazepines and time to death. For every 1 mg/h increase in benzodiazepine use, time to death was increased by 13 min (p = 0.015). There was no relationship between narcotic dose and time to death during the last 2 h of life (p = 0.11). CONCLUSIONS: We found no evidence that the use of narcotics or benzodiazepines to treat discomfort after the withdrawal of life support hastens death in critically ill patients at our center. Clinicians should strive to control patient symptoms in this setting and should document the rationale for escalating drug doses. PMID: 15249473 [PubMed - indexed for MEDLINE]
Evidence Based Prognostication - AAHPM Annual Assembly 2007 February 14, 2007 Sinclair, Salacz, Affield Clinical predictors and outcomes for patients requiring tracheostomy in the intensive care unit. Kollef MH , Ahrens TS , Shannon W . Department of Medicine, Washington University School of Medicine, St.Louis, MO, USA. OBJECTIVE: To identify clinical predictors for tracheostomy among patients requiring mechanical ventilation in the intensive care unit (ICU) setting and to describe the outcomes of patients receiving a tracheostomy. DESIGN: Prospective cohort study. SETTING: Intensive care units of Barnes-Jewish Hospital, an urban teaching hospital. PATIENTS: 521 patients requiring mechanical ventilation in an ICU for >12 hours. INTERVENTIONS: Prospective patient surveillance and data collection. MEASUREMENTS AND MAIN RESULTS: The main variables studied were hospital mortality, duration of mechanical ventilation, length of stay in the ICU and the hospital, and acquired organ-system derangements. Fifty-one (9.8%) patients received a tracheostomy. The hospital mortality of patients with a tracheostomy was statistically less than the hospital mortality of patients not receiving a tracheostomy (13.7% vs. 26.4%; p = .048), despite having a similar severity of illness at the time of admission to the ICU (Acute Physiology and Chronic Health Evaluation [APACHE] II scores, 19.2 +/- 6.1 vs. 17.8 +/- 7.2; p = .173). Patients receiving a tracheostomy had significantly longer durations of mechanical ventilation (19.5 +/- 15.7 days vs. 4.1 +/- 5.3 days; p < .001) and hospitalization (30.9 +/- 18.1 days vs. 12.8 +/- 10.1 days; p < .001) compared with patients not receiving a tracheostomy. Similarly, the average duration of intensive care was significantly longer among the hospital nonsurvivors receiving a tracheostomy (n = 7) compared with the hospital nonsurvivors without a tracheostomy (n = 124; 30.9 +/- 16.3 days vs. 7.9 +/- 7.3 days; p < .001). Multiple logistic regression analysis demonstrated that the development of nosocomial pneumonia (adjusted odds ratio [AOR], 4.72; 95% confidence interval [CI], 3.24-6.87; p < .001), the administration of aerosol treatments (AOR, 3.00; 95% CI, 2.184.13; p < .001), having a witnessed aspiration event (AOR, 3.79; 95% CI, 2.30-6.24; p = .008), and requiring reintubation (AOR, 2.21; 95% CI, 1.54-3.18; p = .028) were variables independently associated with patients undergoing tracheostomy and receiving prolonged ventilatory support. Among the 44 survivors receiving a tracheostomy in the ICU, 38 (86.4%) were alive 30 days after hospital discharge and 31 (70.5%) were living at home. CONCLUSIONS: Despite having longer lengths of stay in the ICU and hospital, patients with respiratory failure who received a tracheostomy had favorable outcomes compared with patients who did not receive a tracheostomy. These data suggest that physicians are capable of selecting critically ill patients who most likely will benefit from placement of a tracheostomy. Additionally, specific clinical variables were identified as risk factors for prolonged ventilatory assistance and the need for tracheostomy.
Evidence Based Prognostication - AAHPM Annual Assembly 2007 February 14, 2007 Sinclair, Salacz, Affield 5 year 65% with cancer For example, a serum albumin of less than 3.0 g/dL versus greater than 4.0 g/dL confers a 4.4 times greater risk of death; a serum albumin level of less than 3.5 g/dL is associated with a 1–year mortality of approximately 50%. For stage 5 CKD patients, poor functional status is also highly predictive of early death. Fifteen studies examining the relationship between functional status and mortality found a significant association with early death. Measures used to assess functional status have included the Karnofsky or Modified Karnofsky Scale, the Gutman functional status, activities of daily living, and Medical Outcomes Study 36-item Short Form (SF-36).2 In 2000, Beddhu
