BACKGROUND: The purpose of this study was to determine the incidence of candiduria in critically ill patients admitted to intensive care medical units (ICUs), to identify risk factors for candiduria and to assess the frequency distribution of different Candidaspp. SUBJECTS AND METHODS: This was a prospective cohort observational and multicenter study. A total of 1,765 patients older than 18 years of age who were admitted for at least 7 days to 73 medical-surgical ICUs of 70 Spanish hospitals were included in the study. Urine cultures were performed once a week. RESULTS. In 389 patients (22%), Candidaspp. in one or more urine samples were isolated. In the multivariate analysis, independent risk factors for candiduria included: age >65 years, female sex, length of hospital stay before ICU admission, diabetes mellitus, total parenteral nutrition, mechanical ventilation and previous use of antimicrobials. Candida albicanswas recovered in 266 cases (68.4%), followed by C. glabrata(32 cases, 8.2%) and C. tropicalis(14 cases, 36%). Previous use of antifungal agents was the only risk factor for the selection of Candidanon-albicans candiduria (OR 2.64, 95% CI 1.35-5.14, P=0.004). In-hospital mortality was 48.8% in patients with candiduria compared to 36.6% in those without candiduria ( P<0.001). Significant differences were also found for ICU mortality (38.% vs. 28.1%, P<0.001). CONCLUSIONS: Twenty-two percent of critically ill patients admitted for more than 7 days in the ICU developed candiduria. C. albicanswas the most frequent causative pathogen. Previous use of antifungals was the only risk factor for the selection of Candidanon-albicans. 相似文献

Objective
The objective of this study is to identify factors predicting intensive care unit (ICU) mortality in cancer patients admitted to a medical ICU.Patients and methods
We conducted a retrospective study in 162 consecutive cancer patients admitted to the medical ICU of a 1000-bed university hospital between January 2009 and June 2012. Medical history, physical and laboratory findings on admission, and therapeutic interventions during ICU stay were recorded. The study end point was ICU mortality. Logistic regression analysis was performed to identify independent risk factors for ICU mortality.Results
The study cohort consisted of 104 (64.2%) patients with solid tumors and 58 patients (35.8%) with hematological malignancies. The major causes of ICU admission were sepsis/septic shock (66.7%) and respiratory failure (63.6%), respectively. Overall ICU mortality rate was 55 % (n = 89). The ICU mortality rates were similar in patients with hematological malignancies and solid tumors (57% vs 53.8%; P = .744). Four variables were independent predictors for ICU mortality in cancer patients: the remission status of the underlying cancer on ICU admission (odds ratio [OR], 0.113; 95% confidence interval [CI], 0.027-0.48; P = .003), Acute Physiology and Chronic Health Evaluation II score (OR, 1.12; 95% CI, 1.032-1.215; P = .007), sepsis/septic shock during ICU stay (OR, 8.94; 95% CI, 2.28-35; P = .002), and vasopressor requirement (OR 16.84; 95% CI, 3.98-71.24; P = .0001). Although Acute Physiology and Chronic Health Evaluation II score (OR, 1.30; 95% CI, 1.054-1.61; P = .014), admission through emergency service (OR, 0.005; 95% CI, 0.00-0.69; P = .035), and vasopressor requirement during ICU stay (OR, 140.64; 95% CI, 3.59-5505.5; P = .008) were independent predictors for ICU mortality in patients with hematological malignancies, Sequential Organ Failure Assessment score (OR, 1.83; 95% CI, 1.29-2.6; P = .001), lactate dehydrogenase level on admission (OR, 1.002; 95% CI, 1-1.005; P = .028), sepsis/septic shock during ICU stay (OR, 138.4; 95% CI, 12.54-1528.4; P = .0001), and complete or partial remission of the underlying cancer (OR, 0.026; 95% CI, 0.002-0.3; P = .004) were the independent risk factors in patients with solid tumors.Conclusion
Intensive care unit mortality rate was 55% in our cancer patients, which suggests that patients with cancer can benefit from ICU admission. We also found that ICU mortality rates of patients with hematological malignancies and solid tumors were similar. 相似文献3.
Outcome and prognostic factors in critically ill cancer patients admitted to the intensive care unit
Staudinger T Stoiser B Müllner M Locker GJ Laczika K Knapp S Burgmann H Wilfing A Kofler J Thalhammer F Frass M 《Critical care medicine》2000,28(5):1322-1328
OBJECTIVE: To assess survival in cancer patients admitted to an intensive care unit (ICU) with respect to the nature of malignancy, cause of ICU admittance, and course during ICU stay as well as to evaluate the prognostic value of the Acute Physiology and Chronic Health Evaluation (APACHE) III score. DESIGN: Retrospective cohort study. SETTING: ICU at a university cancer referral center. PATIENTS: A total of 414 cancer patients admitted to the ICU during a period of 66 months. INTERVENTIONS: None. MEASUREMENTS: Charts of the patients were analyzed with respect to underlying disease, cause of admission, APACHE III score, need and duration of mechanical ventilation, neutropenia and development of septic shock, as well as ICU survival and survival after discharge. Mortality data were compared with two control groups: 1362 patients admitted to our ICU suffering from diseases other than cancer and 2,776 cancer patients not admitted to the ICU. MAIN RESULTS: ICU survival was 53%, and 1-yr survival was 23%. The 1-yr mortality rate was significantly lower in both control groups. Patients admitted after bone marrow transplantation had the highest mortality. In a multivariate analysis, prognosis was negatively influenced by respiratory insufficiency, the need of mechanical ventilation, and development of septic shock during the ICU stay. Admission after cardiopulmonary resuscitation yielded high ICU mortality but a relatively good long-term prognosis. Admission after surgery and as a result of acute hemorrhage was associated with a good prognosis. Age, neutropenia, and underlying disease did not influence outcome significantly. Admission APACHE III scores were significantly higher in nonsurvivors but failed to predict individual outcome satisfactorily. All patients with APACHE III scores of >80 died at the ICU. CONCLUSION: A combination of factors must be taken into account to estimate a critically ill cancer patient's prognosis in the ICU. The APACHE III scoring system alone should not be used to make decisions about therapy prolongation. Admission to the ICU worsens the prognosis of a cancer patient substantially; however, as ICU mortality is 47%, comparable with severely ill noncancer patients, general reluctance to admit cancer patients to an ICU does not seem to be justified. 相似文献

The provision of artificial nutrition for critically ill patients is of great importance as many are unable to maintain their own nutritional needs. The administration of total parenteral nutrition (TPN) and enteral nutrition (EN) has become a daily practice in intensive care units. Despite this, many patients remain undernourished or even malnourished and it is estimated that the incidence of malnutrition in intensive care patients could be as high as 50% (McCain, 1993). The reasons by which patients become or remain undernourished are multifactorial and range from physiological to iatrogenic. In order to lessen the catabolic state which results from the hypermetabolism associated with critical illness, prompt and adequate nutritional support must be delivered. It is essential that members of the multidisciplinary team caring for critically ill patients are aware of the importance of nutrition and the deleterious effects of malnutrition to achieve the best possible outcome for patients. 相似文献

Objective
Despite an improvement in the prognosis of patients with hematologic malignancies, the mortality of such patients transferred to the intensive care unit (ICU) is high. This study determined the predictors of mortality in a cohort of critically ill patients with hematologic malignancies admitted to the ICU.Methods
We studied 227 critically ill patients with hematologic malignancies who were admitted to the ICU between April 2009 and December 2011. A cohort of consecutive patients with hematologic malignancies was reviewed retrospectively to identify clinically useful prognostic factors.Results
The ICU mortality rate was 84.1%, and the in-hospital mortality rate was 89.9%. The ICU mortality was significantly higher in patients with acute leukemia than in those with other malignancies. A significant difference between survivors and nonsurvivors was found in neutropenia and its recovery during the ICU stay, presence of cardiac dysfunction, the need for an invasive mechanical ventilator, use of inotropic/vasopressor agents, platelet count, aspartate transaminase level, pH, and Acute Physiology And Chronic Health Evaluation II score. In the multivariate analysis, acute leukemia, need for invasive mechanical ventilator, use of inotropic/vasopressor agents, and Acute Physiology And Chronic Health Evaluation II scores were independently associated with a worse outcome in patients with hematologic malignancies admitted to the ICU.Conclusion
Higher mortality in patients with hematologic malignancies admitted to the ICU is associated with more severe illness, as reflected by higher organ failure scores or respiratory or hemodynamic instability. Mortality is higher in patients with acute leukemia as compared with other hematologic malignancies. 相似文献8.

BACKGROUND: Readmission to intensive care unit (ICU) after discharge to ward has been reported to be associated with increased hospital mortality and longer length of stay (LOS). The objective of this study was to investigate whether ICU readmission are preventable in critically ill cancer patients.METHODS: Data of patients who readmitted to intensive care unit (ICU) at National Cancer Center/Cancer Hospital of Chinese Academy of Medical Sciences (CAMS) and Peking Union Medical College (PUMC) between January 2013 and November 2016 were retrospectively collected and reviewed.RESULTS: A total of 39 patients were included in the final analysis, and the overall readmission rate between 2013 and 2016 was 1.32% (39/2,961). Of 39 patients, 32 (82.1%) patients were judged as unpreventable and 7 (17.9%) patients were preventable. There were no significant differences in duration of mechanical ventilation, ICU LOS, hospital LOS, ICU mortality and in-hospital mortality between patients who were unpreventable and preventable. For 24 early readmission patients, 7 (29.2%) patients were preventable and 17 (70.8%) patients were unpreventable. Patients who were late readmission were all unpreventable. There was a trend that patients who were preventable had longer 1-year survival compared with patients who were unpreventable (100% vs. 66.8%, log rank=1.668, P=0.196).CONCLUSION: Most readmission patients were unpreventable, and all preventable readmissions occurred in early period after discharge to ward. There were no significant differences in short term outcomes and 1-year survival in critically ill cancer patients whose readmissions were preventable or not. 相似文献

Introduction
Clinicians and specialty societies often emphasize the potential importance of natural light for quality care of critically ill patients, but few studies have examined patient outcomes associated with exposure to natural light. We hypothesized that receiving care in an intensive care unit (ICU) room with a window might improve outcomes for critically ill patients with acute brain injury. 相似文献10.

Purpose.?Earlier and more intense rehabilitation benefit stroke patients. Yet, studies have caution intensive therapy during acute brain injury. This study examined the rehabilitation commencement time and intensity as predictors of functional outcomes in acute stroke patients admitted to the stroke intensive care unit (ICU).Method.?Sociodemographic, medical, rehabilitative and functional data were collected on 154 acute stroke patients. Regression analyses were used to identify predictors for the basic activities of daily living (Barthel Index, BI) and the walking ability at discharge.Result.?Rehabilitation commencement time and intensity significantly predicted the BI score at discharge after adjusting for initial severity (National Institute of Health Stroke Scale, NIHSS) and age (p?<?0.05). For the walking function at discharge, only the rehabilitation intensity was a significant predictor after adjusting for initial severity and age (p?<?0.05). Furthermore, with increasing rehabilitation intensity, patients with severe stroke benefited more than those with moderate stroke.Conclusion.?Rehabilitation commencement time and intensity, after adjusting for admission functional status and severity of stroke, remained to be important predictors of stroke functional outcomes. This study supported the recommendation to commence rehabilitation early and intensively and provided evidence that this claim can be extended to acute stroke patients admitted to an ICU. 相似文献

Objective To determine the concomitant incidence, molecular diversity, management and outcome of nosocomial candidemia and candiduria
in intensive care unit (ICU) patients in France.
Design A 1-year prospective observational study in 24 adult ICUs.
Patients Two hundred and sixty-two patients with nosocomial candidemia and/or candiduria.
Measurements and results Blood and urine samples were collected when signs of sepsis were present. Antifungal susceptibility of Candida strains was determined; in addition, all blood and 72% of urine C. albicans isolates were analyzed by using multi-locus sequence type (MLST). The mean incidences of candidemia and candiduria were 6.7
and 27.4/1000 admissions, respectively. Eight percent of candiduric patients developed candidemia with the same species. The
mean interval between ICU admission and candidemia was 19.0 ± 2.9 days, and 17.2 ± 1.1 days for candiduria. C. albicans and C. glabrata were isolated in 54.2% and 17% of blood and 66.5% and 21.6% of urine Candida-positive cultures, respectively. Fluconazole was the most frequently prescribed agent. In all candidemic patients, the prescribed
curative antifungal agent was active in vitro against the responsible identified strain. Crude ICU mortality was 61.8% for
candidemic and 31.3% for candiduric patients. Seventy-five percent of the patients were infected with a unique C. albicans strain; cross-transmission between seven patients was suggested in one hospital.
Conclusions Candidemia is late-onset ICU-acquired infection associated with high mortality. No difference in susceptibility and genetic
background were found between blood and urine strains of Candida species.

Purpose
This study aimed to establish which prognostic scoring tool provides the greatest discriminative ability when assessing critically ill cirrhotic patients in a general intensive care unit (ICU) setting.Methods
This was a 12-month, single-centered prospective cohort study performed in a general, nontransplant ICU. Forty clinical and demographic variables were collected on admission to calculate 8 prospective scoring tools. Patients were followed up to obtain ICU and inhospital mortality. Receiver operating characteristic curve analysis was used to determine the discriminative ability of the scores. Univariate and multivariate analyses were used to identify any independent predictors of mortality in these patients. The incorporation of any significant variables into the scoring tools was assessed.Results
Fifty-nine cirrhotic patients were admitted over the study period, with an ICU mortality of 31%. All scores other than the renal-specific Acute Kidney Injury Network score had similar discriminative abilities, producing area under the curves of between 0.70 and 0.76. None reached the clinically applicable level of 0.8. The Sequential Organ Failure Assessment score was the best performing score.Lactate and ascites were individual predictors of ICU mortality with statistically significant odds ratios of 1.69 and 5.91, respectively. When lactate was incorporated into the Child-Pugh score, its prognostic accuracy increased to a clinically applicable level (area under the curve, 0.86).Conclusions
This investigation suggests that established prognostic scoring systems should be used with caution when applied to the general, nontransplant ICU as compared to specialist centers. Our data suggest that serum arterial lactate may improve the prognostic ability of these scores. 相似文献13.

Introduction
Epidemiologic assessment of critically ill people in Intensive Care Units (ICUs) is needed to ensure the health care system can meet current and future needs. However, few such studies have been published.Methods
Population-based analysis of all adult ICU care in the Canadian province of Manitoba, 1999 to 2007, using administrative data. We calculated age-adjusted rates and trends of ICU care, overall and subdivided by age, sex and income.Results
In 2007, Manitoba had a population of 1.2 million, 118 ICU beds in 21 ICUs, for 9.8 beds per 100,000 population. Approximately 0.72% of men and 0.47% of women were admitted to ICUs yearly. The age-adjusted, male:female rate ratio was 1.75 (95% CI 1.64 to 1.88). Mean age was 64.5 ± 16.4 years. Rates rose rapidly after age 40, peaked at age 75 to 80, and declined for the oldest age groups. Rates were higher among residents of lower income areas, for example declining from 7.9 to 4.4 per 100,000 population from the poorest to the wealthiest income quintiles (p <0.0001). Rates of ICU admission slowly declined over time, while cumulative yearly ICU bed-days slowly rose; changes were age-dependent, with faster declines in admission rates with older age. There was a high rate of recidivism; 16% of ICU patients had received ICU care previously.Conclusions
These temporal trends in ICU admission rates and cumulative bed-days used have significant implications for health system planning. The differences by age, sex and socioeconomic status, and the high rate of recidivism require further research to clarify their causes, and to devise strategies for reducing critical illness in high-risk groups. 相似文献14.
Hutchison and colleagues report a 10-year experience of dialysis patients admitted to intensive care units (ICUs) in the UK excluding Scotland. Their study is the largest published so far and raises issues of interest to both ICU physicians and nephrologists. Overall, the dialysis patients, although sicker on admission and having pre-existing co-morbidities, do as well as other ICU patients. Their clinical progress after leaving the ICU, however, is less good than for other ICU patients, raising the possibility that the patients might be leaving too early, or perhaps that dialysis patients should be discharged to a high-dependency unit rather than go direct to a renal ward. All in all, the paper by Hutchison and colleagues provides a useful foundation for planning the critical care management of dialysis patients in the UK and elsewhere. 相似文献

OBJECTIVE: To characterize the symptom experience of a cohort of intensive care unit (ICU) patients at high risk for hospital death. DESIGN: Prospective analysis of patients with a present or past diagnosis of cancer who were consecutively admitted to a medical ICU during an 8-month period. SETTING: Academic, university-affiliated, tertiary-care, urban medical center. PATIENTS: One hundred cancer patients treated in a medical ICU. INTERVENTION: Assessment of symptoms. MEASUREMENTS: Patients' self-reports of symptoms using the Edmonton Symptom Assessment Scale (ESAS), and ratings of pain or discomfort associated with ICU diagnostic/therapeutic procedures and of stress associated with conditions in the ICU. MAIN RESULTS: Hospital mortality for the group was 56%. Fifty patients had the capacity to respond to the ESAS, among whom 100% provided symptom reports. Between 55% and 75% of ESAS responders reported experiencing pain, discomfort, anxiety, sleep disturbance, or unsatisfied hunger or thirst that they rated as moderate or severe, whereas depression and dyspnea at these levels were reported by approximately 40% and 33% of responders, respectively. Significant pain, discomfort, or both were associated with common ICU procedures, but most procedure-related symptoms were controlled adequately for a majority of patients. Inability to communicate, sleep disruption, and limitations on visiting were particularly stressful among ICU conditions studied. CONCLUSIONS: Among critically ill cancer patients, multiple distressing symptoms were common in the ICU, often at significant levels of severity. Symptom assessment may suggest more effective strategies for symptom control and may direct decisions about appropriate use of ICU therapies. 相似文献

Characteristics and outcomes for critically ill patients with prolonged intensive care unit stays 总被引:4,自引:0,他引:4
OBJECTIVE: Prolonged stay in the intensive care unit (ICU) is associated with high mortality, morbidity, and costs. Identifying those patients who are most likely to benefit from an extended ICU stay would be helpful in guiding clinical decisions. We sought to describe the characteristics and outcomes for a heterogeneous group of patients who required a prolonged ICU stay. DESIGN: Observational study. SETTING: Adult ICUs of three teaching and five community hospitals. PATIENTS: The study group comprised 5,881 patients consecutively admitted to the ICUs during a 10-month period. MEASUREMENTS AND MAIN RESULTS: A prolonged stay was defined as one >21 days at teaching hospitals and >10 days at community hospitals. For patients meeting the criteria of prolonged stay, Therapeutic Intervention Scoring System (TISS) score and Multiple Organ Dysfunction Score (MODS) were measured prospectively from days 10 and 21 in community and teaching hospitals, respectively, and retrospectively before this. Prolonged-stay patients represented 5.6% of ICU admissions and 39.7% of ICU bed-days. Compared with short-stay patients, they were significantly older and had higher admission Acute Physiology and Chronic Health Evaluation (APACHE) II scores (p < .01). ICU and hospital mortality for prolonged-stay patients were 24.4% and 35.2%, respectively, compared with 11% and 15.9% for short-stay patients (p < .001). Mean admission TISS and MODS scores for prolonged-stay patients were 30.8 (sd, 11.1) and 4.8 (sd, 3.3) respectively. For prolonged-stay patients the dominant reason for ICU care was multiple organ failure (37.8%), ventilator support (30.7%), or nonventilated single organ failure (31.5%). Hospital mortality was highest in the group with multiple organ failure (53%). CONCLUSIONS: We developed a method to broadly classify a heterogeneous population of prolonged-stay ICU patients on the basis of MODS and the ICU interventions received. Mortality among prolonged-stay patients was highest for those with multiple organ failure. Future research should evaluate whether the proposed classification system can be used to influence the delivery of ICU care. 相似文献

OBJECTIVE: The demand for intensive care beds far exceeds their availability in many European countries. Consequently, many critically ill patients occupy hospital beds outside intensive care units, throughout the hospital. The outcome of patients who fit intensive care unit admission criteria but are hospitalized in regular wards needs to be assessed for policy implications. The object was to screen entire hospital patient populations for critically ill patients and compare their 30-day survival in and out of the intensive care unit. DESIGN: Screening teams visited every hospital ward on four selected days in five acute care Israeli hospitals. The teams listed all patients fitting a priori developed study criteria. One-month data for each patient were abstracted from the medical records. SETTING: Five acute care Israeli hospitals. PATIENTS: All patients fitting a priori developed study criteria. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Survival in and out of the intensive care unit was compared for screened patients from the day a patient first met study criteria. Cox multivariate models were constructed to adjust survival comparisons for various confounding factors. The effect of intensive care unit vs. other departments was estimated separately for the first 3 days after deterioration and for the remaining follow-up time. Results showed that 5.5% of adult hospitalized patients were critically ill (736 of 13,415). Of these, 27% were admitted to intensive care units, 24% to specialized care units, and 49% to regular departments. Admission to an intensive care unit was associated with better survival during the first 3 days of deterioration, after we adjusted for age and severity of illness (p =.018). There was no additional survival advantage for intensive care unit patients (p =.9) during the remaining follow-up time. CONCLUSIONS: The early survival advantage in the intensive care unit suggests a window of critical opportunity for these patients. Under economic constraints and dearth of intensive care unit beds, increasing the turnover of patients in the intensive care unit, thus exposing more needy patients to the early benefit of treatment in the intensive care unit, may be advantageous. 相似文献

Introduction
When the number of patients who require intensive care is greater than the number of beds available, intensive care unit (ICU) entry flow is obstructed. This phenomenon has been associated with higher mortality rates in patients that are not admitted despite their need, and in patients that are admitted but are waiting for a bed. The purpose of this study is to evaluate if a delay in ICU admission affects mortality for critically ill patients. 相似文献19.
