Six-Month Morbidity and Mortality among Intensive Care Unit Patients Receiving Life-Sustaining Therapy. A Prospective Cohort Study.

ABSTRACT:

Rationale

Understanding long-term outcomes of critically ill patients may inform shared decision-making in the intensive care unit (ICU).

Objectives

To quantify 6-month functional outcomes of general ICU patients, and develop a multivariable model comprising factors present during the first ICU day to predict which patients will return to their baseline function 6 months later.

Methods

We conducted a prospective cohort study in three medical ICUs and two surgical ICUs in three hospitals. We enrolled patients who spent at least 3 days in the ICU and received mechanical ventilation for more than 48 hours and/or vasoactive infusions for more than 24 hours.

Results

We measured 6-month outcomes including survival, return to original place of residence, and physical and cognitive function. Of 303 enrolled patients, 299 (98.7%) had complete follow-up at 6 months. Among the 169 patients (56.5%) who survived to 6 months, 82.8% returned home, 81.9% were able to toilet, 71.3% were able to ambulate 10 stairs, and 62.4% reported normal cognition. Overall, 31.1% of patients returned to their baseline status on these measures. Factors associated with not returning to baseline included higher APACHE III score, being a medical patient, older age, nonwhite race, recent hospitalization, prior transplantation, and a history of cancer or of neurologic or liver disease. A model including only these Day 1 factors had good discrimination (area under receiver operating characteristic curve, 0.778; 95% confidence interval, 0.724-0.832) and calibration (difference between observed and expected P value, 0.36).

Conclusions

Among patients spending at least 3 days in an ICU and requiring even brief periods of life-sustaining therapy, nearly one-half will be dead and less than one-third will have returned to their baseline status at 6 months. Of those who survive, the majority of patients will be back at home at 6 months. Future research is needed to validate this multivariable model, including readily available patient characteristics available on the first ICU day, that seems to identify patients who will return to baseline at 6 months.

Project description:INTRODUCTION: Acute kidney injury (AKI) has high incidence among the critically ill and associates with dismal outcome. Not only the long-term survival, but also the quality of life (QOL) of patients with AKI is relevant due to substantial burden of care regarding these patients. We aimed to study the long-term outcome and QOL of patients with AKI treated in intensive care units. METHODS: We conducted a predefined six-month follow-up of adult intensive care unit (ICU) patients from the prospective, observational, multi-centre FINNAKI study. We evaluated the QOL of survivors with the EuroQol (EQ-5D) questionnaire. We included all participating sites with at least 70% rate of QOL measurements in the analysis. RESULTS: Of the 1,568 study patients, 635 (40.5%, 95% confidence interval (CI) 38.0-43.0%) had AKI according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Of the 635 AKI patients, 224 (35.3%), as compared to 154/933 (16.5%) patients without AKI, died within six months. Of the 1,190 survivors, 959 (80.6%) answered the EQ-5D questionnaire at six months. The QOL (median with Interquartile range, IQR) measured with the EQ-5D index and compared to age- and sex-matched general population was: 0.676 (0.520-1.00) versus 0.826 (0.812-0.859) for AKI patients, and 0.690 (0.533-1.00) versus 0.845 (0.812-0.882) for patients without AKI (P?<0.001 in both). The EQ-5D at the time of ICU admission was available for 774 (80.7%) of the six-month respondents. We detected a mean increase of 0.017 for non-AKI and of 0.024 for AKI patients in the EQ-5D index (P?=?0.728). The EQ-5D visual analogue scores (median with IQR) of patients with AKI (70 (50-83)) and patients without AKI (75 (60-87)) were not different from the age- and sex-matched general population (69 (68-73) and 70 (68-77)). CONCLUSIONS: The health-related quality of life of patients with and without AKI was already lower on ICU admission than that of the age- and sex-matched general population, and did not change significantly during critical illness. Patients with and without AKI rate their subjective health to be as good as age and sex-matched general population despite statistically significantly lower QOL indexes measured by EQ-5D.

Project description:ImportanceThe Chinese Neonatal Network was established in 2018 and maintains a standardized national clinical database of very preterm or very low-birth-weight infants in tertiary neonatal intensive care units (NICUs) throughout China. National-level data on outcomes and care practices of very preterm infants (VPIs) in China are lacking.ObjectiveTo assess the care practices in NICUs and outcomes among VPIs in China.Design, setting, and participantsA cohort study was conducted comprising 57 tertiary hospitals from 25 provinces throughout China. All infants with gestational age (GA) less than 32 weeks who were admitted to the 57 NICUs between January 1 and December 31, 2019, were included.Main outcomes and measuresCare practices, morbidities, and survival were the primary outcomes of the study. Major morbidities included bronchopulmonary dysplasia, severe intraventricular hemorrhage (grade ≥3) and/or periventricular leukomalacia, necrotizing enterocolitis (stage ≥2), sepsis, and severe retinopathy of prematurity (stage ≥3).ResultsA total of 9552 VPIs were included, with mean (SD) GA of 29.5 (1.7) weeks and mean (SD) birth weight of 1321 (321) g; 5404 infants (56.6%) were male. Antenatal corticosteroids were used in 75.6% (6505 of 8601) of VPIs, and 54.8% (5211 of 9503)were born through cesarean delivery. In the delivery room, 12.1% of VPIs received continuous positive airway pressure and 26.7% (2378 or 8923) were intubated. Surfactant was prescribed for 52.7% of the infants, and postnatal dexamethasone was prescribed to 9.5% (636 of 6675) of the infants. A total of 85.5% (8171) of the infants received complete care, and 14.5% (1381) were discharged against medical advice. The incidences of the major morbidities were bronchopulmonary dysplasia, 29.2% (2379 of 8148); severe intraventricular hemorrhage and/or periventricular leukomalacia, 10.4% (745 of 7189); necrotizing enterocolitis, 4.9% (403 of 8171 ); sepsis, 9.4% (764 of 8171); and severe retinopathy of prematurity, 4.3% (296 of 6851) among infants who received complete care. Among VPIs with complete care, 95.4% (7792 of 8171) survived: 65.6% (155 of 236) at 25 weeks' or less GA, 89.0% (880 of 988) at 26 to 27 weeks' GA, 94.9% (2635 of 2755)at 28 to 29 weeks' GA, and 98.3% (4122 of 4192) at 30 to 31 weeks' GA. Only 57.2% (4677 of 8171) of infants survived without major morbidity: 10.5% (25 of 236) at 25 weeks' or less GA, 26.8% (48 of 179) at 26 to 27 weeks' GA, 51.1% (1409 of 2755) at 28 to 29 weeks' GA, and 69.3% (2904 of 4192) at 30 to 31 weeks' GA. Among all infants admitted, the survival rate was 87.6% (8370 of 9552)and survival without major morbidities was 51.8% (4947 of 9552).Conclusions and relevanceThe findings of this study suggest that survival and survival without major morbidity of VPIs in Chinese NICUs have improved but remain lower than in high-income countries. Comprehensive and targeted quality improvement efforts are needed to provide complete care for all VPIs, optimize obstetrical and neonatal care practices, and improve outcomes.

Project description:PurposeThe final decision for discharge from the intensive care unit (ICU) is uncertain because it is made according to various patient parameters; however, it should be made on an objective evaluation. Previous reports have been inconsistent and unreliable in predicting post-ICU mortality. To identify predictive factors associated with post-ICU mortality, we analyzed physiological and laboratory data at ICU discharge.MethodsPatients admitted to our ICU between September 2012 and August 2013 and staying for critical care>2 days were included. Sequential Organ Failure Assessment (SOFA) score; systemic inflammatory response syndrome score; white blood cell count; and serum C reactive protein, procalcitonin (PCT), interleukin-6 (IL-6), lactate, albumin, and hemoglobin levels were recorded. The primary end point was 90-day mortality after ICU discharge. Two hundred eighteen patients were enrolled (195 survivors, 23 non-survivors).ResultsNon-survivors presented a higher SOFA score and serum PCT, and IL-6 levels, as well as lower serum albumin and hemoglobin levels. Serum PCT, albumin, and SOFA score were associated with 90-day mortality in multiple logistic regression analysis. Hosmer-Lemeshow test showed chi-square value of 6.96, and P value of 0.54. The area under the curve (95% confidence interval) was 0.830 (0.771-0.890) for PCT, 0.688 (0.566-0.810) for albumin, 0.861 (0.796-0.927) for SOFA score, and increased to 0.913 (0.858-0.969) when these were combined. Serum PCT level at 0.57 ng/mL, serum albumin at 2.5 g/dL and SOFA score at 5.5 predict 90-day mortality, and high PCT, low albumin and high SOFA groups had significantly higher mortality. Serum PCT and SOFA score were significantly associated with survival days after ICU discharge in Cox regression analysis.ConclusionsSerum PCT level and SOFA score at ICU discharge predict post-ICU mortality and survival days after ICU discharge. The combination of these two and albumin level might enable accurate prediction.

Project description:INTRODUCTION: The aim of this study was to evaluate the usefulness of the APACHE II (Acute Physiology and Chronic Health Evaluation II), SAPS II (Simplified Acute Physiology Score II) and SOFA (Sequential Organ Failure Assessment) scores compared to simpler models based on age and Glasgow Coma Scale (GCS) in predicting long-term outcome of patients with moderate-to-severe traumatic brain injury (TBI) treated in the intensive care unit (ICU). METHODS: A national ICU database was screened for eligible TBI patients (age over 15 years, GCS 3-13) admitted in 2003-2012. Logistic regression was used for customization of APACHE II, SAPS II and SOFA score-based models for six-month mortality prediction. These models were compared to an adjusted SOFA-based model (including age) and a reference model (age and GCS). Internal validation was performed by a randomized split-sample technique. Prognostic performance was determined by assessing discrimination, calibration and precision. RESULTS: In total, 1,625 patients were included. The overall six-month mortality was 33%. The APACHE II and SAPS II-based models showed good discrimination (area under the curve (AUC) 0.79, 95% confidence interval (CI) 0.75 to 0.82; and 0.80, 95% CI 0.77 to 0.83, respectively), calibration (P?>?0.05) and precision (Brier score 0.166 to 0.167). The SOFA-based model showed poor discrimination (AUC 0.68, 95% CI 0.64 to 0.72) and precision (Brier score 0.201) but good calibration (P?>?0.05). The AUC of the SOFA-based model was significantly improved after the insertion of age and GCS (?AUC +0.11, P?<?0.001). The performance of the reference model was comparable to the APACHE II and SAPS II in terms of discrimination (AUC 0.77; compared to APACHE II, ?AUC -0.02, P?=?0.425; compared to SAPS II, ?AUC -0.03, P?=?0.218), calibration (P?>?0.05) and precision (Brier score 0.181). CONCLUSIONS: A simple prognostic model, based only on age and GCS, displayed a fairly good prognostic performance in predicting six-month mortality of ICU-treated patients with TBI. The use of the more complex scoring systems APACHE II, SAPS II and SOFA added little to the prognostic performance.
