Survival of critically ill patients hospitalized in and out of intensive care.

OBJECTIVE: A lack of intensive care units beds in Israel results in critically ill patients being treated outside of the intensive care unit. The survival of such patients is largely unknown. The present study's objective was to screen entire hospitals for newly deteriorated patients and compare their survival in and out of the intensive care unit. DESIGN: A priori developed intensive care unit admission criteria were used to screen, during 2 wks, the patient population for eligible incident patients. A screening team visited every hospital ward of five acute care hospitals daily. Eligible patients were identified among new admissions in the emergency department and among hospitalized patients who acutely deteriorated. Patients were followed for 30 days for mortality regardless of discharge. SETTING: Five acute care hospitals. PATIENTS: A total of 749 newly deteriorated patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Crude survival of patients in and out of the intensive care unit was compared by Kaplan-Meier curves, and Cox models were constructed to adjust the survival comparisons for residual case-mix differences. A total of 749 newly deteriorated patients were identified among 44,000 patients screened (1.7%). Of these, 13% were admitted to intensive care unit, 32% to special care units, and 55% to regular departments. Intensive care unit patients had better early survival (0-3 days) relative to regular departments (p=.0001) in a Cox multivariate model. Early advantage of intensive care was most pronounced among patients who acutely deteriorated while on hospital wards rather than among newly admitted patients. CONCLUSIONS: Only a small proportion of eligible patients reach the intensive care unit, and early admission is imperative for their survival advantage. As intensive care unit benefit was most pronounced among those deteriorating on hospital wards, intensive care unit triage decisions should be targeted at maximizing intensive care unit benefit by early admitting patients deteriorating on hospital wards.

Attitudes of European physicians, nurses, patients, and families regarding end-of-life decisions: the ETHICATT study.

OBJECTIVE: To evaluate attitudes of Europeans regarding end-of-life decisions. DESIGN AND SETTING: Responses to a questionnaire by physicians and nurses working in ICUs, patients who survived ICU, and families of ICU patients in six European countries were compared for attitudes regarding quality and value of life, ICU treatments, active euthanasia, and place of treatment. MEASUREMENTS AND RESULTS: Questionnaires were distributed to 4,389 individuals and completed by 1,899 (43%). Physicians (88%) and nurses (87%) found quality of life more important and value of life less important in their decisions for themselves than patients (51%) and families (63%). If diagnosed with a terminal illness, health professionals wanted fewer ICU admissions, uses of CPR, and ventilators (21%, 8%, 10%, respectively) than patients and families (58%, 49%, 44%, respectively). More physicians (79%) and nurses (61%) than patients (58%) and families (48%) preferred being home or in a hospice if they had a terminal illness with only a short time to live. CONCLUSIONS: Quality of life was more important for physicians and nurses than patients and families. More medical professionals want fewer ICU treatments and prefer being home or in a hospice for a terminal illness than patients and families.

An evaluation of systemic inflammatory response syndrome signs in the Sepsis Occurrence In Acutely Ill Patients (SOAP) study.

OBJECTIVE: To define the frequency and prognostic implications of SIRS criteria in critically ill patients hospitalized in European ICUs. DESIGN AND SETTING: Cohort, multicentre, observational study of 198 ICUs in 24 European countries. PATIENTS AND INTERVENTIONS: All 3,147 new adult admissions to participating ICUs between 1 and 15 May 2002 were included. Data were collected prospectively, with common SIRS criteria. RESULTS: During the ICU stay 93% of patients had at least two SIRS criteria [respiratory rate (82%), heart rate (80%)]. The frequency of having three or four SIRS criteria vs. two was higher in infected than non-infected patients (p < 0.01). In non-infected patients having more than two SIRS criteria was associated with a higher risk of subsequent development of severe sepsis (odds ratio 2.6, p < 0.01) and septic shock (odds ratio 3.7, p < 0.01). Organ system failure and mortality increased as the number of SIRS criteria increased. CONCLUSIONS: Although common in the ICU, SIRS has prognostic importance in predicting infections, severity of disease, organ failure and outcome.

Sepsis in European intensive care units: results of the SOAP study.

OBJECTIVE: To better define the incidence of sepsis and the characteristics of critically ill patients in European intensive care units. DESIGN: Cohort, multiple-center, observational study. SETTING: One hundred and ninety-eight intensive care units in 24 European countries. PATIENTS: All new adult admissions to a participating intensive care unit between May 1 and 15, 2002. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Demographic data, comorbid diseases, and clinical and laboratory data were collected prospectively. Patients were followed up until death, until hospital discharge, or for 60 days. Of 3,147 adult patients, with a median age of 64 yrs, 1,177 (37.4%) had sepsis; 777 (24.7%) of these patients had sepsis on admission. In patients with sepsis, the lung was the most common site of infection (68%), followed by the abdomen (22%). Cultures were positive in 60% of the patients with sepsis. The most common organisms were Staphylococcus aureus (30%, including 14% methicillin-resistant), Pseudomonas species (14%), and Escherichia coli (13%). Pseudomonas species was the only microorganism independently associated with increased mortality rates. Patients with sepsis had more severe organ dysfunction, longer intensive care unit and hospital lengths of stay, and higher mortality rate than patients without sepsis. In patients with sepsis, age, positive fluid balance, septic shock, cancer, and medical admission were the important prognostic variables for intensive care unit mortality. There was considerable variation between countries, with a strong correlation between the frequency of sepsis and the intensive care unit mortality rates in each of these countries. CONCLUSIONS: This large pan-European study documents the high frequency of sepsis in critically ill patients and shows a close relationship between the proportion of patients with sepsis and the intensive care unit mortality in the various countries. In addition to age, a positive fluid balance was among the strongest prognostic factors for death. Patients with intensive care unit acquired sepsis have a worse outcome despite similar severity scores on intensive care unit admission.

Does dopamine administration in shock influence outcome? Results of the Sepsis Occurrence in Acutely Ill Patients (SOAP) Study.

OBJECTIVE: The optimal adrenergic support in shock is controversial. We investigated whether dopamine administration influences the outcome from shock. DESIGN: Cohort, multiple-center, observational study. SETTING: One hundred and ninety-eight European intensive care units. PATIENTS: All adult patients admitted to a participating intensive care unit between May 1 and May 15, 2002. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients were followed up until death, until hospital discharge, or for 60 days. Shock was defined as hemodynamic compromise necessitating the administration of vasopressor catecholamines. Of 3,147 patients, 1,058 (33.6%) had shock at any time; 462 (14.7%) had septic shock. The intensive care unit mortality rate for shock was 38.3% and 47.4% for septic shock. Of patients in shock, 375 (35.4%) received dopamine (dopamine group) and 683 (64.6%) never received dopamine. Age, gender, Simplified Acute Physiology Score II, and Sequential Organ Failure Assessment score were comparable between the two groups. The dopamine group had higher intensive care unit (42.9% vs. 35.7%, p=.02) and hospital (49.9% vs. 41.7%, p=.01) mortality rates. A Kaplan-Meier survival curve showed diminished 30 day-survival in the dopamine group (log rank=4.6, p=.032). In a multivariate analysis with intensive care unit outcome as the dependent factor, age, cancer, medical admissions, higher mean Sequential Organ Failure Assessment score, higher mean fluid balance, and dopamine administration were independent risk factors for intensive care unit mortality in patients with shock. CONCLUSIONS: This observational study suggests that dopamine administration may be associated with increased mortality rates in shock. There is a need for a prospective study comparing dopamine with other catecholamines in the management of circulatory shock.

End-of-life care in the intensive care unit: the Irish Ethicus data.

OBJECTIVE: To study the frequency, rationale and process for withholding (WH) and withdrawing (WD) life-sustaining therapies in intensive care patients in Ireland. DESIGN: Prospective, observational study, comprising a subset of the European Ethicus Study. SETTING AND PARTICIPANTS: 122 patients who died or who had life-sustaining therapies limited in the ICU of a university hospital, 1 September 1999 to 30 June 2000. OUTCOME MEASURES AND RESULTS: An end-of-life (EOL) treatment decision was made for 85/122 patients (69%). Forty-five (36%) had therapy withheld, 40 (33%) had it withdrawn, 26 (21%) had unsuccessful cardiopulmonary resuscitation, and 11 (10%) suffered brain death. The median time from ICU admission to death was 4.0 days for WH patients and 2.9 days for WD patients (range, 10 minutes to 123 days). The discussion to limit therapy was initiated by the ICU doctor in 50 cases (59%), and involved families in 66 cases (78%). Families initiated 9% of EOL discussions. Nursing staff were involved in 98% of decisions. No patients were mentally competent, but their wishes were known in 28% of cases. The primary reason for limiting life-sustaining therapy was that the patient was unresponsive to maximum therapy (68% of patients). An EOL decision was made every 55 hours during "office hours" and every 120 hours during "on-call" working hours. Withholding was more frequent than withdrawing during "on call" periods. DISCUSSION: The frequency of withdrawal or withholding of therapy in this Irish ICU is in line with current international practice. The time to EOL decision-making is variable and relatively short compared with that in the United States, but similar to that in Europe. Clinicians are the primary initiators of the EOL decision in Ireland, with little patient involvement. Family members are more likely to initiate an EOL decision than in Europe. EOL decisions were usually made during "routine" working hours after significant consultation with all groups.

Nurse involvement in end-of-life decision making: the ETHICUS Study.

OBJECTIVE: The purpose was to investigate physicians' perceptions of the role of European intensive care nurses in end-of-life decision making. DESIGN: This study was part of a larger study sponsored by the Ethics Section of the European Society of Intensive Care Medicine, the ETHICUS Study. Physicians described whether they thought nurses were involved in such decisions, whether nurses initiated such a discussion and whether there was agreement between physicians and nurses. The items were analyzed and comparisons were made between different regions within Europe. SETTING: The study took place in 37 intensive care units in 17 European countries. PATIENTS AND PARTICIPANTS: Physician investigators reported data related to patients from 37 centers in 17 European countries. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Physicians perceived nurses as involved in 2,412 (78.3%) of the 3,086 end-of-life decisions (EOLD) made. Nurses were thought to initiate the discussion in 66 cases (2.1%), while ICU physicians were cited in 2,438 cases (79.3%), the primary physician in 328 cases (10.7%), the consulting physician in 105 cases (3.4%), the family in 119 cases (3.9%) and the patient in 19 cases (0.6%). In only 20 responses (0.6%) did physicians report disagreement between physicians and nurses related to EOLD. A significant association was found between the region and responses to the items related to nursing. Physicians in more northern regions reported more nurse involvement. CONCLUSIONS: Physicians perceive nurses as involved to a large extent in EOLDs, but not as initiating the discussion. Once a decision is made, there is a sense of agreement. The level of perceived participation is different for different regions.

Is albumin administration in the acutely ill associated with increased mortality? Results of the SOAP study.

INTRODUCTION: Albumin administration in the critically ill has been the subject of some controversy. We investigated the use of albumin solutions in European intensive care units (ICUs) and its relationship to outcome. METHODS: In a cohort, multicenter, observational study, all patients admitted to one of the participating ICUs between 1 May and 15 May 2002 were followed up until death, hospital discharge, or for 60 days. Patients were classified according to whether or not they received albumin at any time during their ICU stay. RESULTS: Of 3,147 admitted patients, 354 (11.2%) received albumin and 2,793 (88.8%) did not. Patients who received albumin were more likely to have cancer or liver cirrhosis, to be surgical admissions, and to have sepsis. They had a longer length of ICU stay and a higher mortality rate, but were also more severely ill, as manifested by higher simplified acute physiology score (SAPS) II and sequential organ failure assessment (SOFA) scores than the other patients. A Cox proportional hazard model indicated that albumin administration was significantly associated with decreased 30-day survival. Moreover, in 339 pairs matched according to a propensity score, ICU and hospital mortality rates were higher in the patients who had received albumin than in those who had not (34.8 versus 20.9% and 41.3 versus 27.7%, respectively, both p < 0.001). CONCLUSION: Albumin administration was associated with decreased survival in this population of acutely ill patients. Further prospective randomized controlled trials are needed to examine the effects of albumin administration in sub-groups of acutely ill patients.

Cortisol changes among patients with septic shock and the relationship to ICU and hospital stay.

OBJECTIVE: To evaluate adrenal function in patients with severe sepsis or septic shock. DESIGN: A prospective study of unstimulated and high-dose ACTH stimulated cortisol levels on days 1 and 2 following ICU admission and day 28 or last day of hospitalization (herein day 28). SETTING: General intensive care unit. PATIENTS: 34 septic patients. INTERVENTIONS: On days 1, 2, and 28 of sepsis unstimulated and ACTH stimulated cortisol levels were evaluated. End-points were length of ICU and hospital stay and 28 day all cause mortality. MEASUREMENTS AND RESULTS: Eight patients on days 1 and 2 had criteria of adrenal insufficiency defined as unstimulated cortisol levels less than 15 microg/dl. Patients with unstimulated cortisol levels less than 15 microg/dl on day 1 or change of 9 microg/dl or less had longer ICU stays. Patients with unstimulated cortisol levels less than 15 microg/dl on day 1 also demonstrated longer hospital stay. On day 1 regression analysis revealed that unstimulated cortisol levels had a significant inverse correlation with length of ICU and hospital stay. The proportional change between unstimulated cortisol and post-ACTH cortisol (Delta%) is a new modality; the higher this Delta% value, the longer is the patient's ICU and hospital stay. A significant positive correlation was found in survivors when comparing unstimulated cortisol vs. day 28 changes. CONCLUSIONS: The present study highlights the wide range of cortisol levels among patients with sepsis. We observed a difference in cortisol response pattern between survivors and nonsurvivors on day 28. The proportional change between unstimulated cortisol and post-ACTH cortisol was used as a method to evaluate the relative change in cortisol levels between patients.

Clinical review: the Israeli experience: conventional terrorism and critical care.

Over the past four years there have been 93 multiple-casualty terrorist attacks in Israel, 33 of them in Jerusalem. The Hadassah-Hebrew University Medical Center is the only Level I trauma center in Jerusalem and has therefore gained important experience in caring for critically injured patients. To do so we have developed a highly flexible operational system for managing the general intensive care unit (GICU). The focus of this review will be on the organizational steps needed to provide operational flexibility, emphasizing the importance of forward deployment of intensive care unit personnel to the trauma bay and emergency room and the existence of a chain of command to limit chaos. A retrospective review of the hospital's response to multiple-casualty terror incidents occurring between 1 October 2000 and 1 September 2004 was performed. Information was assembled from the medical center's trauma registry and from GICU patient admission and discharge records. Patients are described with regard to the severity and type of injury. The organizational work within intensive care is described. Finally, specific issues related to the diagnosis and management of lung, brain, orthopedic and abdominal injuries, caused by bomb blast events associated with shrapnel, are described. This review emphasizes the importance of a multidisciplinary team approach in caring for these patients.

Withdrawing and withholding life-sustaining therapies are not the same.

Numerous lines of evidence support the premise that withholding and withdrawing life support measures in the intensive care unit are not the same. These include questionnaires, practical observations and an examination of national medical guidelines. It is important to distinguish between the two end of life options as their outcomes and management are significantly different. Appreciation of these differences allows the provision of accurate information, and facilitates decision making that is compassionate, caring and adherent to the needs of the patient and their family.

Assessing the in-hospital survival benefits of intensive care.

OBJECTIVES: For an efficient and fair allocation of medical resources, one must know which patients benefit more from medical care. The objective of this study is to assess the differential survival benefits of a general intensive care unit (ICU) by acute diagnoses and by Acute Physiological and Chronic Health Evaluation (APACHE II) scores. METHODS: The sample included all patients triaged for admission to the Hadassah-Hebrew University Medical Center ICU during a 7-month period (n = 381). The potential effect of ICU on in-hospital survival was estimated by a bivariate (admission-survival) probit model, using crowding in the unit as the identifying variable, controlling for observable patients characteristics: age, sex, acute diagnoses, and APACHE II score. Using the estimates, the differential predicted survival benefits of ICU were calculated for selected general acute diagnoses and for different APACHE II scores. RESULTS: Adjusting for age, sex, and general acute diagnoses, the average potential survival benefit of ICU is 17 percentage points (pts). The benefit of ICU for patients with central nervous system problems, with sepsis, or with respiratory failure are higher than average (23 pts). Adjusting for APACHE II scores as well increases the estimated average potential benefit to 21 pts. Over the range of APACHE II scores, the highest benefit (38 pts of potential benefit) is attained for patients with scores around 22. CONCLUSIONS: Survival benefits differ across diagnoses and APACHE II scores. Facing limited resources, admission policies should distinguish between survival probabilities (and survival maximization) and survival benefits (and maximization of ICU benefits). Actual referral and admission policies to the present ICU do not maximize the potential survival benefits of ICU resources.

Myocardial ischemia, cardiac troponin, and long-term survival of high-cardiac risk critically ill intensive care unit patients.

OBJECTIVES: To determine the incidence and association of myocardial ischemia with troponin elevation and survival in high-cardiac-risk intensive care patients. DESIGN: Prospective observational study. SETTING: Intensive care unit of a tertiary hospital. SUBJECTS: One-hundred one general intensive care unit patients having a history of coronary artery disease or at least two risk factors for coronary artery disease. INTERVENTIONS: Continuous 12-lead electrocardiographic monitoring with on-line ST-trend analysis, daily cardiac troponin measurements, clinical and physiologic assessment, and up to 2-yr follow-up for survival. MEASUREMENTS AND MAIN RESULTS: During 8,988 hrs or a mean +/- sd of 95 +/- 85 hrs/patient of continuous 12-lead electrocardiographic monitoring, 21 patients (21%) had ischemic ST-segment changes, characterized in most (19) by ST depression and lasting >60 mins in 15 (71.4%). Of the 38 patients (38%) with troponin elevation, myocardial infarction was clinically suspected in four and myocardial ischemia on continuous 12-lead electrocardiographic monitoring was observed in 14 (36.8%). Fourteen (66.7%) of the patients with ischemic ST changes and 12 (75%) of those with prolonged (>60 mins) ischemia had troponin elevation. The sensitivity, specificity, and positive and negative predictive values of prolonged (>60 mins) ischemia predicting troponin elevation were 31.6%, 95.2%, 80.0%, and 69.8%, respectively. Prolonged (>60 mins) ischemia was significantly associated with troponin elevation by both univariate and multivariate analyses (odds ratio = 9.0; p = .008). Acute Physiology and Chronic Health Evaluation II score, renal failure, and the use of norepinephrine also independently predicted troponin elevation. Troponin but not ischemia predicted increased 1-month, 6-month, and 2-yr mortality (odds ratio = 6.0, 3.2, and 2.99, respectively; p < .001). CONCLUSIONS: Silent ischemia is strongly associated with troponin elevation in high-cardiac-risk intensive care unit patients, and troponin elevation predicts both early and late mortality.
