Abstract
BACKGROUND This study examined preoperative, intraoperative, and postoperative data to identify factors that are associated with prolonged mechanical ventilation (PMV) and prolonged intensive care unit length of stay (ICU LOS) in tetralogy of Fallot (TOF) patients undergoing repair surgery. METHODS A retrospective study was carried out after approval from the institutional review board. All patients (age 0-52 years) who underwent TOF repair from January 2016 to September 2022 were included. Prolonged mechanical ventilation was defined as >24 h of ventilation, while prolonged ICU LOS was defined as ICU stay >3 days. RESULTS A total of 922 patients were included, among whom 288 (31.2%) were intubated for >24 h and 222 (24.1%) stayed in ICU for >3 days. Younger age (odds ratio [OR] = 2, 95% confidence interval [CI] 1.2-3.3, P = .007), lower weight (OR = 2.1, 95% CI 1.2-3.5, P = .003), and residual lesion (OR = 3.27, 95% CI 1.2-8.7, P = .017) were associated with PMV. Moreover, independent risk factors for prolonged ICU LOS are similar to PMV risk factors, including younger age (OR = 2.3, 95% CI 1.28-4.12, P = .005), lower weight (OR = 2.83, 95% CI 1.58-5, P < .001), underweight status (OR = 1.7, 95% CI 1.12-2.57, P = .012), and residual lesion (OR = 3.79, 95% CI 1.43-10.05, P = .007). Both aortic cross-clamp and cardiopulmonary bypass times did not exhibit clinically significant risk factors toward PMV and prolonged ICU LOS. CONCLUSIONS The risk factors for PMV and prolonged ICU LOS were residual lesion, younger age, and lower weight. Nutritional status contributed to the risk of prolonged ICU LOS, but not PMV. Consideration of these factors may provide optimal care to improve the outcome following TOF corrective surgery.

ICF framework in cardiac rehabilitation: a real-life implementation in post-cardiac surgery and chronic heart failure patients. Eur J Phys Rehabil Med 2023; 59:605-614. [PMID: 37377129 PMCID: PMC10664764 DOI: 10.23736/s1973-9087.23.07666-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 04/26/2023] [Accepted: 06/05/2023] [Indexed: 06/29/2023]
Abstract
BACKGROUND The International Classification of Functioning, Disability, and Health (ICF) is growing in importance in cardiac rehabilitation (CR) as the number of elderly comorbid patients increases. AIM To classify through the ICF framework a group of post-cardiac surgery (CS) and chronic heart failure (CHF) patients undergoing rehabilitation. Then, to compare the two groups and identify possible factors at admission that could affect ICF evaluations at discharge. DESIGN Observational retrospective real-life study. SETTING Two inpatient CR units. POPULATION Consecutive CS and CHF patients admitted for CR (January-December 2019). METHODS Clinical, anthropometric data and functional status at admission and discharge were extracted from patient health records. A set of 26 ICF codes regarding body functions (b) and activities (d) was analyzed to identify: 1) the qualifiers attributed (from 0=no impairment to 4=severe impairment) for each code, 2) the percent distribution of qualifiers (0/1/2/3/4) attributed per patient. We then evaluated changes in both (1) and (2 - defined as ICF Delta%) from admission to discharge. RESULTS All patients (55% males; mean age 73±12 years) showed an improvement post-rehabilitation in the ICF qualifiers attributed (P<0.0001 for all codes). CS patients (N.=150) were less functionally impaired at admission than CHF (N.=194) (P<0.05 for all codes), and at discharge showed greater Delta% in the qualifiers 0/1/2 attributed than CHF (P<0.0001 for b codes; P<0.05 for d codes). Delta% for qualifiers 3 and 4 was similar in the two groups. No impairment at admission (qualifier 0), CS group, and presence/complexity of comorbidities were identified as possible covariates influencing ICF qualifiers at discharge, impacting the rate of both no/mild impairment (ICF% aggregate 0+1 - adjusted R2=0.627; P<0.0001) and moderate impairment (ICF% qualifier 2 - adjusted R2=0.507; P<0.0001). CONCLUSIONS CHF patients showed a worse ICF picture at admission and less improvement at discharge than CS. The presence and complexity of comorbidities negatively influenced the ICF classification at discharge, especially in CHF patients. CLINICAL REHABILITATION IMPACT This study shows the utility of ICF classification in CR as a means for describing, measuring, and comparing patient functioning across the care continuum.

Abstract
Background Identifying risk factors associated with cardiac intensive care unit (CICU) patients' prognosis can help clinicians intervene earlier and thus improve their prognosis. The correlation between the geriatric nutrition risk index (GNRI), which reflects nutritional status, and in-hospital mortality among CICU patients has yet to be established. Method The present study retrospectively enrolled 4,698 CICU patients. Based on the nutritional status, the participants were categorized into four groups. The primary endpoint was in-hospital mortality. The length of hospital stay and length of CICU stay were the secondary endpoints. To explore the correlation between nutritional status and in-hospital mortality, a logistic regression analysis was conducted. The nonlinear associations of GNRI with in-hospital mortality were evaluated using restricted cubic spline (RCS). Furthermore, subgroup analyses were conducted to evaluate the effect of the GNRI on in-hospital mortality across different subgroups, with calculation of the p for interaction. Result A higher risk of malnutrition was significantly linked to an increased incidence of in-hospital mortality (High risk vs. No risk: 26.2% vs. 4.6%, p < 0.001), as well as a longer length of hospital stay (High risk vs. No risk: 15.7, 9.1-25.1 vs. 8.9, 6.9-12.9, p < 0.001) and CICU stay (High risk vs. No risk: 6.4, 3.8-11.9 vs. 3.2, 2.3-5.1, p < 0.001). An elevated GNRI was significantly associated with an increased risk of in-hospital mortality even after controlling for pertinent confounding factors (High risk vs. No risk: OR, 95% CI: 2.37, 1.67-3.37, p < 0.001, p for trend <0.001). Additionally, the RCS model showed a linear relationship between GNRI and in-hospital mortality, with the risk of in-hospital mortality significantly decreasing as GNRI increased (non-linear p = 0.596). Furthermore, in the subgroups of hypertension, ventricular arrhythmias, cardiac arrest, shock, and chronic kidney disease, there was a significant interaction between nutritional status and in-hospital mortality. Conclusion Among CICU patients, a low GNRI was a significant predictor of in-hospital mortality. Furthermore, patients with a higher risk of malnutrition, as indicated by low GNRI values, experienced significantly longer hospital and CICU stays.

Abstract
The COVID-19 pandemic has been shown to affect both physical and mental health. Because of this mental health burden, it is important to pay attention to issues such as the relationship between spiritual health, death attitudes and meaning in life - all issues made more prominent during the pandemic. This study was conducted to determine the correlation between these three factors - spiritual health, meaning in life, and death attitudes, among patients with COVID-19 discharged from the intensive care units of hospitals affiliated with Tehran University of Medical Sciences, Tehran, Iran.This cross-sectional, descriptive-analytical study was conducted between April 2020 and August 2021 with 260 participants. The data collection instruments were a demographic characteristics questionnaire, Polotzin and Ellison's Spiritual Health Questionnaire, The Meaning in Life Questionnaire (MLQ), and Death Attitude Profile-Revised (DAP-R).The correlation between meaning in life, spiritual health, and death attitudes was determined by Spearman's correlation coefficient. The research results showed that there is an inverse and significant correlation between spiritual health and death attitudes (p = 0.01); an inverse, but insignificant correlation between existential health and subscales of death attitudes, except for the subscales of approach acceptance and neutral acceptance (p > 0.05); and an inverse, but insignificant, correlation between spiritual health and death attitudes, (p > 0.05). In addition, there was an inverse and significant correlation between the presence of meaning in life and escape acceptance (p = 0.002); an inverse and significant correlation between the search for meaning in life and neutral acceptance (p = 0.007); and an inverse and significant correlation between the meaning in life and death attitudes (p = 0.04). Besides, the findings showed an inverse but insignificant correlation between all spiritual health subscales and the meaning in life subscales (p > 0.05). Spiritual health has an inverse correlation with death attitudes.Also, there is an inverse correlation between the total score of spiritual health and death attitudes. Regarding the subscales of spiritual health, there is an inverse correlation between existential health and death attitudes subscales, except for approach acceptance and neutral acceptance. Also, the results showed an inverse and significant correlation between meaning in life and death acceptance and avoidance subscales, and there was an inverse and significant correlation between the meaning in life and death attitudes. Finally, the increase in spiritual health reduces patients' risks of thinking about death. The research results double the significance of the role of nurses, especially those dealing with critically ill patients and those who have experienced severe disease conditions.

The impact of daylight and window views on length of stay among patients with heart disease: A retrospective study in a cardiac intensive care unit. JOURNAL OF INTENSIVE MEDICINE 2023; 3:155-164. [PMID: 37188123 PMCID: PMC10175739 DOI: 10.1016/j.jointm.2022.11.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 11/01/2022] [Accepted: 11/11/2022] [Indexed: 05/17/2023]
Abstract
Background Heart disease is the leading cause of death in the United States. The length of stay (LOS) is a well-established parameter used to evaluate health outcomes among critically ill patients with heart disease in cardiac intensive care units (CICUs). While evidence suggests that the presence of daylight and window views can positively influence patients' LOS, no studies to date have differentiated the impact of daylight from window views on heart disease patients. Also, existing research studies on the impact of daylight and window views have failed to account for key clinical and demographic variables that can impact the benefit of such interventions in CICUs. Methods This retrospective study investigated the impact of access to daylight vs. window views on CICU patients' LOS. The study CICU is located in a hospital in the southeast United States and has rooms of the same size with different types of access to daylight and window views, including rooms with daylight and window views (with the patient bed located parallel to full-height, south-facing windows), rooms with daylight and no window views (with the patient bed located perpendicular to the windows), and windowless rooms. Data from electronic health records (EHRs) for the time-period September 2015 to September 2019 (n=2936) were analyzed to investigate the impact of room type on patients' CICU LOS. Linear regression models were developed for the outcome of interest, controlling for potential confounding variables. Results Ultimately, 2319 patients were finally included in the study analysis. Findings indicated that patients receiving mechanical ventilation in rooms with access to daylight and window views had shorter LOS durations (16.8 h) than those in windowless rooms. Sensitivity analysis for a subset of patients with LOS ≤3 days revealed that parallel bed placement to the windows and providing access to both daylight and window views significantly reduced their LOS compared to windowless rooms in the unit (P=0.007). Also, parallel bed placement to the window significantly reduced LOS in this patient subset for those with an experience of delirium (P=0.019), dementia (P=0.008), anxiety history (P=0.009), obesity (P=0.003), and those receiving palliative care (P=0.006) or mechanical ventilation (P=0.033). Conclusions Findings from this study could help architects make design decisions and determine optimal CICU room layouts. Identifying the patients who benefit most from direct access to daylight and window views may also help CICU stakeholders with patient assignments and hospital training programs.

Abstract
OBJECTIVE To determine the effect of intensive care unit (ICU) length of stay (LOS) on hospital mortality and non-home discharge for patients undergoing cardiac surgery over a 16-year period in Australia and New Zealand. DESIGN A retrospective, multicenter cohort study covering the period January 1, 2004 to December 31, 2019. SETTING One hundred one hospitals in Australia and New Zealand that submitted data to the Australia New Zealand Intensive Care Society Adult Patient Database. PARTICIPANTS Adult patients (aged >18) who underwent coronary artery bypass grafting, valve surgery, or combined valve + coronary artery surgery. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The authors analyzed 252,948 cardiac surgical patients from 101 hospitals, with a median age of 68.3 years (IQR 60-75.5), of whom 74.2% (187,632 of 252,948) were male patients. A U-shaped relationship was observed between ICU LOS and hospital mortality, with significantly elevated mortality at short (<20 hours) and long (>5 days) ICU LOS, which persisted after adjustment for illness severity and across clinically important subgroups (odds ratio for mortality with ICU LOS >5 days = 3.21, 95% CI 2.88-3.58, p < 0.001). CONCLUSIONS Prolonged duration of ICU LOS after cardiac surgery is associated with increased hospital mortality in a U-shaped relationship. An ICU LOS >5 days should be considered a meaningful definition for prolonged ICU stay after cardiac surgery.

Abstract
Background Medical therapy is the standard treatment for uncomplicated acute type B aortic dissection (ATBAD), but there is little evidence of the need for intensive care unit (ICU) management. Therefore, we aimed to investigate the effects of ICU treatment on uncomplicated ATBAD. Methods We retrospectively studied patients with uncomplicated ATBAD who were medically treated between January 2010 and July 2020. Patients were divided into short-term ICU stay (SIS) and long-term ICU stay (LIS) groups, according to a 48-hour cutoff of ICU stay duration. The incidence of pneumonia and delirium, rate of aortic events, hospital mortality, and survival rate were compared. Results Fifty-five patients were treated for uncomplicated ATBAD (n=29 for SIS and n=26 for LIS). The incidence of pneumonia (3.6% vs. 7.7%) and delirium (14.3% vs. 34.6%) was higher in the LIS group than in the SIS group, but the differences were not statistically significant. The survival rates at 1, 3, and 5 years were not different between the two groups (SIS: 96.4%, 92.2%, and 75.5% vs. LIS: 96.2%, 88.0%, and 54.2%, respectively; p=0.102). Multivariate Cox regression analysis for aortic events showed that using a calcium channel blocker lowered the risk of aortic events. Conclusion Long-term ICU treatment is unlikely to be necessary for the treatment of uncomplicated ATBAD. Active use of antihypertensive agents, such as calcium channel blockers, may be needed during the follow-up period.

Abstract
Introduction: Our aim was to use the red cell distribution width-lymphocyte ratio (RLR) as a novel biomarker to predict prolonged intensive care unit (ICU) length of stay (LOS) among older patients undergoing cardiovascular surgery. Methods: This longitudinal study included older patients admitted to a tertiary cardiovascular surgery hospital between January 2017 and January 2022. Results: A total of 574 patients were studied, including 83 patients (14.5%) who had prolonged ICU LOS and 471 (85.5%) control subjects. After adjustment for the European System for Cardiac Operative Risk Evaluation 2, the RLR score showed a 10% increased risk of prolonged ICU LOS (odds ratio: 1.10; CI: 1.05-1.16; p = 0.01). Conclusion: Preoperative RLR can be used to predict the risk of long-term intensive care stay in older cardiac surgery patients.

Abstract
Background: Patients with acute type A aortic dissection are usually transferred to the intensive care unit (ICU) after surgery. Prolonged ICU length of stay (ICU-LOS) is associated with higher level of care and higher mortality. We aimed to develop and validate machine learning models for predicting ICU-LOS after acute type A aortic dissection surgery. Methods: A total of 353 patients with acute type A aortic dissection transferred to ICU after surgery from September 2016 to August 2019 were included. The patients were randomly divided into the training dataset (70%) and the validation dataset (30%). Eighty-four preoperative and intraoperative factors were collected for each patient. ICU-LOS was divided into four intervals (<4, 4–7, 7–10, and >10 days) according to interquartile range. Kendall correlation coefficient was used to identify factors associated with ICU-LOS. Five classic classifiers, Naive Bayes, Linear Regression, Decision Tree, Random Forest, and Gradient Boosting Decision Tree, were developed to predict ICU-LOS. Area under the curve (AUC) was used to evaluate the models' performance. Results: The mean age of patients was 51.0 ± 10.9 years and 307 (87.0%) were males. Twelve predictors were identified for ICU-LOS, namely, D-dimer, serum creatinine, lactate dehydrogenase, cardiopulmonary bypass time, fasting blood glucose, white blood cell count, surgical time, aortic cross-clamping time, with Marfan's syndrome, without Marfan's syndrome, without aortic aneurysm, and platelet count. Random Forest yielded the highest performance, with an AUC of 0.991 (95% confidence interval [CI]: 0.978–1.000) and 0.837 (95% CI: 0.766–0.908) in the training and validation datasets, respectively. Conclusions: Machine learning has the potential to predict ICU-LOS for acute type A aortic dissection. This tool could improve the management of ICU resources and patient-throughput planning, and allow better communication with patients and their families.

Abstract
OBJECTIVE Review a single institution's vestibular schwannoma (VS) microsurgery experience to determine (1) correlations between demographics, comorbidities, and/or surgical approach on hospital length of stay (LOS) and discharge disposition and (2) trends in surgical approach over time. METHODS Retrospective case series from a multidisciplinary skull base program at a tertiary care, academic hospital. All adult (>18 years) patients undergoing primary microsurgery for VS between 2008 and 2018 were included. RESULTS A total of 147 subjects were identified. Surgical approach was split between middle fossa (MF) (16%), retrosigmoid (RS) (35%), and translabyrinthine (TL) (49%) craniotomies. For the 8% of patients had other than routine (OTR) discharge. Mean LOS was significantly longer for patients undergoing RS than either MF or TL. Brainstem compression by the tumor was associated with longer LOS as were diagnoses of chronic obstructive pulmonary disease (COPD) and peripheral vascular disease (PVD). For all discharges, the 40 to 50- and 50 to 60-year-old subgroups had significantly shorter LOS than the 70-years-and-older patients. For the 92% of patients routinely discharged, there was a significantly shorter LOS in the 40 to 50-year-olds compared to the 70-years-and-older patients. There was a significant shift in surgical approach from RS to TL over the study period. CONCLUSION Over 90% of VS microsurgery patients were routinely discharged with a median hospital LOS of 3.2 days, both of which are consistent with published data. There is an inverse relationship between age and LOS with patients older than 70 years having significantly longer LOS. Brainstem compression, COPD, PVD, and the RS approach negatively affect LOS. LEVEL OF EVIDENCE 4.

Abstract
INTRODUCTION Predicting intensive care unit length of stay and outcome following cardiac surgery is currently based on clinical parameters. Novel biomarkers could be employed to improve the prediction models. MATERIALS AND METHODS We performed a qualitative cytokine screening array to identify highly expressed biomarkers in preoperative blood samples of cardiac surgery patients. After identification of one highly expressed biomarker, growth differentiation factor 15 (GDF-15), a quantitative ELISA was undertaken. Preoperative levels of GDF-15 were compared in regard to duration of intensive care stay, cardiopulmonary bypass time, and indicators of organ dysfunction. RESULTS Preoperatively, GDF-15 was highly expressed in addition to several less highly expressed other biomarkers. After qualitative analysis, we could show that preoperatively raised levels of GDF-15 were positively associated with prolonged ICU stay exceeding 48 h (median 713 versus 1041 pg/ml, p = 0.003). It was also associated with prolonged mechanical ventilation and rates of severe sepsis but not with dialysis rates or cardiopulmonary bypass time. In univariate regression, raised GDF-15 levels were predictive of a prolonged ICU stay (OR 1.01, 95% confidence interval 1-1.02, and p = 0.029). On ROC curves, GDF-15 was found to predict prolonged ICU stay (AUC = 0.86, 95% confidence interval 0.71-0.99, and p = 0.003). CONCLUSION GDF-15 showed potential as predictor of prolonged intensive care stay following cardiac surgery, which might be valuable for risk stratification models.

Abstract
BACKGROUND There is a growing need to identify which bits of information are most valuable for healthcare providers. The aim of this study was to search for the highest impact variables in predicting postsurgery length of stay (LOS) for patients who undergo coronary artery bypass grafting (CABG). MATERIALS AND METHODS Using a single institution's Society of Thoracic Surgeons (STS) Registry data, 2121 patients with elective or urgent, isolated CABG were analyzed across 116 variables. Two machine learning techniques of random forest and artificial neural networks (ANNs) were used to search for the highest impact variables in predicting LOS, and results were compared against multiple linear regression. Out-of-sample validation of the models was performed on 105 patients. RESULTS Of the 10 highest impact variables identified in predicting LOS, four of the most impactful variables were duration intubated, last preoperative creatinine, age, and number of intraoperative packed red blood cell transfusions. The best performing model was an ANN using the ten highest impact variables (testing sample mean absolute error (MAE) = 1.685 d, R2 = 0.232), which performed consistently in the out-of-sample validation (MAE = 1.612 d, R2 = 0.150). CONCLUSION Using machine learning, this study identified several novel predictors of postsurgery LOS and reinforced certain known risk factors. Out of the entire STS database, only a few variables carry most of the predictive value for LOS in this population. With this knowledge, a simpler linear regression model has been shared and could be used elsewhere after further validation.

Abstract
Background The CHA2DS2-VASc scoring system is correlated with left atrial (LA) reservoir function in patients with atrial fibrillation (AF) rhythm or paroxysmal AF. We assessed the ability of CHA2DS2-VASc to grade LA function in patients with sinus rhythm who were candidates for coronary artery bypass grafting (CABG). Methods This cross-sectional study recruited 340 consecutive candidates for CABG and categorized them according to their CHA2DS2-VASc scores as mild-, moderate-, and high-risk score groups with 34 (10%), 83 (24%), and 223 (66%) patients, respectively. LA function was evaluated via 2D speckle-tracking echocardiography in terms of global longitudinal strain and strain rate during the reservoir, conduit, and contraction phases. In-hospital mortality, postoperative AF, prolonged intensive care unit (ICU) stay, and prolonged mechanical ventilation were assessed. Results LA strain and strain rate during the reservoir phase was statistically significantly lower in the high-risk score group than the low- and moderate-risk score groups (27.8 ± 6.9% vs 31.0 ± 5.0% vs 29.8 ± 6.1%, respectively; P = 0.004 and 2.6 ± 0.7 s−1 vs 2.9 ± 0.6 s−1 vs 2.9 ± 0.6 s−1, correspondingly; P = 0.009) and regarding LA strain and strain rate during the conduit phase (9.7 [7.1–12.5]% vs 12.9 [9.4–15.1]% vs 11.5 [9.1–13.8]%, correspondingly; P < 0.001 and 2.1 [1.6–2.7] s−1 vs 2.8 [2.4–3.6] s−1 vs 2.6 [2.2–3.0] s−1, respectively; P < 0.001). In addition, LA strain rate during the conduit phase was lower in the moderate-risk score group than the low-risk score group. After adjustments for possible confounders, these differences remained statistically significant. The risk of postoperative AF and prolonged ICU stay was highest in the high-risk score group (relative risk = 9.67 (1.31–71.43) and 8.05 (1.08–60.16), respectively; P = 0.026 and P = 0.042, respectively). Conclusions LA reservoir and conduit functions decreased in the high-risk score group, which was accompanied by an increased risk of postoperative AF and prolonged ICU stay.

Abstract
OBJECTIVE Pulmonary artery catheterization provides continuous monitoring of hemodynamic parameters that may aid in the perioperative management of patients undergoing cardiac surgery. However, prior data suggest that pulmonary artery catheterization has limited benefit in intensive care and surgical settings. Thus, this study sought to determine the impact of pulmonary artery catheter insertion on short-term postoperative outcomes in a large, contemporaneous cohort of patients undergoing open cardiac surgery compared with standard central venous pressure monitoring. METHODS This was an observational study of open cardiac surgeries from 2010 to 2018. Patients with pulmonary artery catheter insertion were identified and matched against patients without pulmonary artery catheter insertion via 1:1 nearest neighbor propensity matching. Multivariable analysis was performed to assess the impact of pulmonary artery catheterization on operative mortality in the overall cohort, as well as recent heart failure, mitral valve disease, and tricuspid insufficiency subgroups. RESULTS Of the 11,820 patients undergoing (Society of Thoracic Surgeons indexed) coronary or valvular surgery, 4605 (39.0%) had pulmonary artery catheter insertion. Propensity score matching yielded 3519 evenly balanced pairs. Compared with central venous pressure monitoring, pulmonary artery catheter use was not associated with improved operative mortality in the overall cohort or in the recent heart failure, mitral valve disease, or tricuspid insufficiency subgroups. Intensive care unit length of stay was longer (P < .001), and there were more packed red blood cell transfusions in the pulmonary artery catheterization group (P < .001); however, postoperative outcomes were otherwise similar, including stroke, sepsis, and new renal failure (P > .05). CONCLUSIONS These findings suggest that pulmonary artery catheterization may have limited benefit in cardiac surgery.

Abstract
OBJECTIVES Prolonged intensive care unit stay after cardiac surgery is associated with high mortality. The aim of this study was to evaluate the impact of the introduction of a quality improvement program under the supervision of an intensivist on the long-term mortality of high-risk patients with prolonged intensive care unit (ICU) stay after cardiac surgery. DESIGN Retrospective study of prospectively collected data. SETTING Cardiac surgery ICU. PARTICIPANTS A total of 7,549 patients after cardiac surgery. INTERVENTIONS Patients were divided into two periods: 2004 to 2007, before introducing the quality improvement program (3,315 patients), and 2009 to 2014, after introduction of the program (4,234 patients). In the period from 2004 to 2007, patients were divided into group I (ICU stay ≥ seven days), which included 242 patients, and group III (ICU stay < seven days), which included 3,073 patients. Also, in the period from 2009 to 2014 patients, were divided into group II (ICU stay ≥seven days), which included 326 patients, and group IV (ICU stay < seven days), which included 3,908 patients. Patient outcomes were compared. Follow-up was five years for each group. MEASUREMENTS AND MAIN RESULTS The European System for Cardiac Operative Risk Evaluation did not differ significantly among the groups. When comparing between group I and group II, 30-day mortality decreased significantly from 24.8% to 16.6%, six-month mortality from 27.3% to 19.3%, one-year mortality from 42.1% to 32.2%, 3-year mortality from 54.5% to 43.3%, and 5-year mortality from 61.2% to 51.8%. In comparing between group III and group IV, the authors did not observe a statistically significant decrease of mortality. CONCLUSIONS Intensivist-led patient management protocol is associated with decreased long-term mortality in high-risk patients with a prolonged ICU stay.

Abstract
OBJECTIVES Short-term outcomes for those with a prolonged length of stay (LOS) in intensive care (ITU) following cardiac surgery are poor, with higher rates of in-hospital mortality and morbidity. Consequently, discharge from hospital has been considered the key measure of success. However, there has been a shift towards long-term outcomes, functional recovery and quality of life (QoL) as measures of surgical quality. The aim of this review is to compare and critique the findings of multiple studies to determine the long-term effects of prolonged ITU stay postcardiac surgery. METHODS A computerized literature search of CINAHL, EMBASE and Google Scholar databases, based on keywords "long-term effects," "prolonged ITU stay," "cardiac surgery," with rigorous CASP critique was undertaken. RESULTS The search yielded 12 papers meeting the inclusion criteria, with eight retrospective and four prospective studies. Eight of these 12 papers identified inferior long-term survival or higher mortality rates for those who had prolonged LOS in ITU in comparison to "normal" LOS or a control. The greatest burden of mortality was 6 months to 1 year postdischarge. Three papers found that quality of life was adversely affected or worse for those who had experienced prolonged LOS in ITU. CONCLUSIONS Further research is required to provide better quality evidence into QoL, following prolonged stay in ICU postcardiac surgery. The evidence reviewed suggests that the risk of mortality in this demographic of patients is higher, especially within the first year and, therefore, more frequent medical surveillance of these patients is recommended.

Abstract
Background:
Coronary artery bypass graft (CABG) is associated with oxidative stress and
tissue damage. Vitamin C, as an antioxidant agent, has an important role in attenuating the oxidative
stress damage and might have cardio-protective effects after CABG. We aimed to evaluate the probable
roles of vitamin C supplementation in cardiac biomarkers after CABG.
Methods::
In this randomized control trial, 122 patients undergoing CABG were randomly assigned
to the intervention (n=54) and control group (n=68) and received vitamin C (2 g intravenously) or
placebo, respectively. The surgical methods of the patients in the two groups were identical. The
primary efficacy endpoint of this trial is the difference in the levels of CK-MB, Troponin and Total
Antioxidant Capacity (TAC) were measured at study entry and 24 hrs after surgery between the two
groups.
Results::
The two groups were not significantly different in terms of basic variables. Within-group
comparison showed significant rises in the level of troponin (P < 0.001) and CK-MB (P < 0.001)
over time. However, between-group comparison showed no significant difference between the two
groups in terms of CK-MB (P=0.826) and troponin (P=0.821). As a whole, the correlation between
cardiac enzymes and surgical characteristic was not seen.
Conclusion::
The results showed that pretreatment with vitamin C could not reduce cardiac marker
following CABG. After the intervention, TAC did not differ between and within the intervention and
the control groups. Pretreatment with vitamin C as an antioxidant agent could not reduce ischemicreperfusion
resulting in CABG.

Abstract
Supplemental Digital Content is available in the text. Objectives: Prolonged admissions to an ICU are associated with high resource utilization and personal cost to the patient. Previous reports suggest increasing length of stay may be associated with poor outcomes. Conditional survival represents the probability of future survival after a defined period of treatment on an ICU providing a description of how prognosis evolves over time. Our objective was to describe conditional survival as length of ICU stay increased. Design: Retrospective observational cohort study of three large intensive care databases. Setting: Three intensive care databases, two in the United States (Medical Information Mart for Intensive Care III and electronic ICU) and one in United Kingdom (Post Intensive Care Risk-Adjusted Alerting and Monitoring). Patients: Index admissions to intensive care for patients 18 years or older. Interventions: None. Measurements and Main Results: A total of 11,648, 38,532, and 165,125 index admissions were analyzed from Post Intensive Care Risk-Adjusted Alerting and Monitoring, Medical Information Mart for Intensive Care III and electronic ICU databases respectively. In all three cohorts, conditional survival declined over the first 5–10 days after ICU admission and changed little thereafter. In patients greater than or equal to 75 years old conditional survival continued to decline with increasing length of stay. Conclusions: After an initial period of 5–10 days, probability of future survival does not decrease with increasing length of stay in unselected patients admitted to ICUs. These findings were consistent between the three populations and suggest that a prolonged admission to an ICU is not a reason for a pessimism in younger patients but may indicate a poor prognosis in the older population.

A Nomogram for Predicting Long Length of Stay in The Intensive Care Unit in Patients Undergoing CABG: Results From the Multicenter E-CABG Registry. J Cardiothorac Vasc Anesth 2020; 34:2951-2961. [PMID: 32620494 DOI: 10.1053/j.jvca.2020.06.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 06/03/2020] [Accepted: 06/04/2020] [Indexed: 12/18/2022]
Abstract
OBJECTIVE Many papers evaluated predictive factors for prolonged intensive care unit (ICU) stay after cardiac surgery, but efforts in translating those models in practical clinical tools is lacking. The aim of this study was to build a new nomogram score and test its calibration and discrimination power for predicting a long length of stay in the ICU among patients undergoing coronary artery bypass graft surgery (CABG). DESIGN Retrospective analysis of an international registry. SETTING Multicentric. PARTICIPANTS Based on the european multicenter study on coronary artery bypass grafting (E-CABG) registry (NCT02319083), a total of 7,352 consecutive patients who underwent isolated CABG were analyzed. INTERVENTIONS A "long length of stay" in the ICU was considered when equal to or more than 3 days. Predictive factors were analyzed through a multivariate logistic regression model that was used for the nomogram. RESULTS Long length of ICU stay was observed in 2,665 patients (36.2%). Ten independent variables were included in the final regression model: the SYNTAX score class critical preoperative state, left ventricular ejection fraction class, angina at rest, poor mobility, recent potent antiplatelet use, estimated glomerular filtration rate class, body mass index, sex, and age. Based on this 10-risk factors logistic regression model, a nomogram has been designed. CONCLUSION The authors defined a nomogram model that can provide an individual prediction of long length of ICU stay in cardiovascular surgical patients undergoing CABG. This type of model would allow an early recognition of high-risk patients who might receive different preoperative and postoperative treatments to improve outcomes.

Abstract
Coronary artery bypass grafting (CABG) triggers a systemic inflammatory response that may contribute to adverse outcomes. Dendritic cells (DC) and monocytes are immunoregulatory cells potentially affected by CABG, contributing to an altered immune state. This study investigated changes in DC and monocyte responses in CABG patients at 5 time-points: admission, peri-operative, ICU, day 3 and day 5. Whole blood from 49 CABG patients was used in an ex vivo whole blood culture model to prospectively assess DC and monocyte responses. Lipopolysaccharide (LPS) was added in parallel to model responses to an infectious complication. Co-stimulatory and adhesion molecule expression and intracellular mediator production was measured by flow cytometry. CABG modulated monocyte and DC responses. In addition, DC and monocytes were immunoparalysed, evidenced by failure of co-stimulatory and adhesion molecules (eg HLA-DR), and intracellular mediators (eg IL-6) to respond to LPS stimulation. DC and monocyte modulation was associated with prolonged ICU length of stay and post-operative atrial fibrillation. DC and monocyte cytokine production did not recover by day 5 post-surgery. This study provides evidence that CABG modulates DC and monocyte responses. Using an ex vivo model to assess immune competency of CABG patients may help identify biomarkers to predict adverse outcomes.

Abstract
OBJECTIVE To compare outcomes between intensivist-directed and cardiac surgeon-directed care delivery models. DESIGN This retrospective, historical-control study was performed in a cohort of adult cardiac surgical patients at Zhongshan Hospital (Fudan University, China). During the first phase (March to August 2015), cardiac surgeons were in charge of postoperative care while intensivists were in charge during the second phase (September 2015-June 2016). Both phases were compared regarding successful extubation rate, intensive care unit (ICU) length of stay (LOS), and in-hospital mortality. SETTING Tertiary Zhongshan Hospital (Fudan University, China). PATIENTS Consecutive adult patients admitted to the cardiac surgical ICU (CSICU) after heart surgery. INTERVENTIONS Phase I patients treated by cardiac surgeons, and phase II patients treated by intensivists. MAIN VARIABLES OF INTEREST Successful extubation, ICU LOS and in-hospital mortality. RESULTS A total of 1792 (phase I) and 3007 patients (phase II) were enrolled. Most variables did not differ significantly between the two phases. However, patients in phase II had a higher successful extubation rate (99.17% vs. 98.55%; p=0.043) and a shorter median duration of mechanical ventilation (MV) (18 vs. 19h; p<0.001). In relation to patients with MV duration >48h, those in phase II had a comparatively higher successful extubation rate (p=0.033), shorter ICU LOS (p=0.038) and a significant decrease in in-hospital mortality (p=0.039). CONCLUSIONS The intensivist-directed care model showed improved rates of successful extubation and shorter MV durations after cardiac surgery.

Morbidity After cardiac surgery under cardiopulmonary bypass and associated factors: A retrospective observational study. Indian Heart J 2019; 71:350-355. [PMID: 31779865 PMCID: PMC6890944 DOI: 10.1016/j.ihj.2019.07.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2018] [Revised: 02/02/2019] [Accepted: 07/30/2019] [Indexed: 12/15/2022] Open
Abstract
Background The present study aimed to assess the morbidity after cardiac surgery and identify the preoperative and intraoperative factors associated with postoperative morbidity. Methods A retrospective observational study was conducted including 362 adult patients aged 18–75 years who underwent open-heart surgery under cardiopulmonary bypass at Sri Jayadeva Institute of Cardiovascular Sciences and Research, Bengaluru, India, during the period from June 2016 to May 2017. Using a structured schedule, preoperative and intraoperative data were collected from the hospital's cardiac surgery database, whereas the postoperative data were collected from the intensive care unit (ICU) database and the hospital's clinical information system database. Results Of 362 patients, 254 (70.2%) had at least one major complication, and the most frequently occurring complication was low cardiac output state (29.8%). The ICU length of stay (LOS) was for > 2 days in 23.2% of patients, and the hospital LOS was for > 7 days in almost 60% of the patients. Multivariate logistic regression analyses revealed that gender, type of surgery, body weight, blood lactate level at ICU admission, and 12-h blood lactate level were significant predictors of complications; gender and 24-h blood lactate level were significantly associated with the prolonged ICU LOS, whereas type of surgery and 24-h blood lactate level were significantly associated with prolonged hospital LOS. Conclusion The appropriate patient management strategy can be tailored based on the personal attributes, surgery type, and blood lactate level for individual patients undergoing cardiac surgery to reduce the likelihood of postoperative complications, ICU LOS, and hospital LOS.

Abstract
BACKGROUND Oropharyngeal dysphagia and laryngeal dysfunction are two lesser known complications after lung and heart transplantation. The presence of these features places this immunocompromised population at high risk of pulmonary complications and subsequent medical deterioration. Early identification of swallowing and voice dysfunction would be beneficial to optimize management. AIMS To examine the association between patient risk factors and postoperative outcomes with referral to speech pathology (SP) following signs of swallowing and voice dysfunction. METHODS & PROCEDURES A retrospective review was conducted on demographic data, patient risk factors and postoperative course in 284 patients following lung and/or heart transplantation between 2010 and 2013. Variables were analysed for any association between pre- and postoperative factors and SP referral. OUTCOMES & RESULTS A total of 24% were referred to SP with a mean age of 47 years. Binary logistic regression identified a statistically significant association between the number of intubations (odds ratio (OR) = 2.066, p = 0.028), intubation duration (OR = 1.004, p < 0.01), length of stay in the intensive care unit (ICU) (OR = 1.068, p < 0.01), and number of ICU admissions (OR = 1.384, p = 0.046) and SP referral. Intubation time and the total days in ICU were greater for patients referred to SP. Mortality also increased for these variables and for the numbers of reintubations and readmissions. Analysis of pre-operative risk factors revealed cerebrovascular disease to be a significant predictor of SP referral (OR = 6.747, p = 0.032). CONCLUSIONS & IMPLICATIONS This study demonstrates significant clinical indicators for referral to SP for the management of oropharyngeal dysphagia and laryngeal dysfunction in patients after lung or heart transplantation. Further studies are needed to investigate the most efficacious intervention approaches to manage swallowing and voice dysfunction in these patients.

Abstract
OBJECTIVES Compared with noncardiac critical illness, critically ill postoperative cardiac surgical patients have different underlying pathophysiologies, are exposed to different processes of care, and thus may experience different outcome trajectories. Our objective was to systematically review the outcomes of cardiac surgical patients requiring prolonged intensive care with respect to survival, residential status, functional recovery, and quality of life in both hospital and long-term follow-up. DATA SOURCES MEDLINE, Embase, CINAHL, Web of Science, and Dissertations and Theses Global up to July 21, 2017. STUDY SELECTION Studies were included if they assessed hospital or long-term survival and/or patient-centered outcomes in adult patients with prolonged ICU stays following major cardiac surgery. After screening 10,159 citations, 114 articles were reviewed in full; a final 34 articles met criteria for data extraction. DATA EXTRACTION Two reviewers independently extracted data and assessed risk of bias using the National Institutes of Health Quality Assessment Tool for Observational Studies. Extracted data included the used definition of prolonged ICU stay, number and characteristics of prolonged ICU stay patients, and any comparator short stay group, length of follow-up, hospital and long-term survival, residential status, patient-centered outcome measure used, and relevant score. DATA SYNTHESIS The definition of prolonged ICU stay varied from 2 days to greater than 14 days. Twenty-eight studies observed greater in-hospital mortality among all levels of prolonged ICU stay. Twenty-five studies observed greater long-term mortality among all levels of prolonged ICU stay. Multiple tools were used to assess patient-centered outcomes. Long-term health-related quality of life and function was equivalent or worse with prolonged ICU stay. CONCLUSIONS We found consistent evidence that patients with increases in ICU length of stay beyond 48 hours have significantly increasing risk of hospital and long-term mortality. The significant heterogeneity in exposure and outcome definitions leave us unable to precisely quantify the risk of prolonged ICU stay on mortality and patient-centered outcomes.

Abstract
Abstract
Background
Emotional and behavioral problems have been noted in a considerable number of patients after open-heart surgery. However, great discrepancy exists in the literature regarding the frequency and the course of psychiatric symptoms, cognitive performance, and quality of life among those patients. This prospective study was designed to assess the pre- and postoperative psychiatric profile, as well as the quality of life of patients undergoing open-heart surgery.
Methods
One hundred patients who were prepared for cardiac surgery and met our selection criteria were recruited in this study. Each patient was subjected to the Hospital Anxiety and Depression Scale, the Mini-Mental State Examination with selective subtests of Wechsler Adult intelligence scale, and the Short Form 36 questionnaire to assess psychiatric symptoms, cognitive performance, and quality of life respectively. Assessment was done for each of the evaluated items before surgery as well as at 1 week and 6 months postoperatively.
Results
The anxiety and depressive symptoms were significantly lower at 6 months postoperatively than preoperatively. The cognitive performance declined after 1 week, then improved significantly at the 6-month follow-up. The quality of life scale was significantly lower preoperatively than after surgery.
Conclusions
Anxiety and depressive symptoms, which occurred in substantial percentage of patients undergoing open-heart surgery, were gradually improved with time. Cognitive functions showed early deterioration with significant improvement at 6 months. Psychiatric problems had an adverse impact on patients’ quality of life which raised the importance of psychiatric consultation before and after cardiac surgeries to shorten recovery time.

Abstract
Introduction Animal models of renal ischemia-reperfusion injury (IRI) demonstrate that interferon (IFN)-γ producing T-helper (Th)-1 cells worsen acute kidney injury (AKI), whereas interleukin (IL)-4– and IL-13–producing Th2 cells lead to repair. We tested the association of these cytokines with AKI and mortality in patients who underwent cardiac surgery. Methods In 1444 participants of a multicenter, prospective, observational cohort, we measured 10 plasma biomarkers before and after cardiac surgery (IFN-γ, IL-4, IL-13, tumor necrosis factor [TNF]-α, IL-1β, IL-2, IL-6, IL-8, IL-10, and IL-12p70) and combined these biomarkers using principal component analysis (PCA). We also tested independent associations of Th1 (IFN-γ) and Th2 (IL-4 and IL-13) biomarkers with clinical outcomes of postoperative AKI and 1-year mortality. Results AKI occurred in 492 participants (34%), and 1-year mortality occurred in 81 participants (6%). Within 6 hours after surgery, IFN-γ, IL-4, and IL-13 increased 2.1-, 6.0-, and 4.6-fold, respectively, from their preoperative levels. Patients with higher levels of IFN-γ had higher odds of AKI (adjusted odds ratio per log change, 1.35 [1.13, 1.6]) and mortality (1.51 [1.17, 1.94]). Patients with higher levels of IL-4 and IL-13 also had higher odds of AKI (1.26 [1.09, 1.46] and 1.4 [1.16, 1.69], respectively) and mortality (1.46 [1.18, 1.82] and 1.71 [1.27, 2.31], respectively). Adding biomarkers to the clinical variables through use of PCA improved the area under the curve by 0.01 for AKI and 0.04 for mortality, resulting in final areas under the curve of 0.85 (0.83–0.87) and 0.76 (0.70–0.81), respectively. Conclusion Both Th1 and Th2 cytokines increased immediately after cardiac surgery and were associated with AKI and 1-year mortality. Our findings indicate activation of both Th1 and Th2 pathways after cardiac surgery rather than predominance of either pathway.

Anesth Pain Med 2019; 9:e81785. [PMID: 30881905 PMCID: PMC6408866 DOI: 10.5812/aapm.81785] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2018] [Revised: 11/07/2018] [Accepted: 11/23/2018] [Indexed: 11/16/2022] Open
Abstract
Background Respiratory failure and hypoxemia are the known complications of anesthesia and surgery. As a major surgery mainly at advanced ages, the coronary artery bypass graft (CABG) surgery could lead to hypoxemia in the early post-operative phase. Currently, the fraction of partial pressure of arterial oxygen to the fraction of inspired oxygen (PiO2/FiO2) is used to determine the severity of the respiratory assault. Objectives This study aimed to find the effect of hypoxemia measured by PaO2/FiO2 at the first hour following CABG in the determination of short-term prognosis of CABG. Methods Being approved by a local ethics committee, this observational cross-sectional study was conducted in 212 patients undergoing CABG on the cardiopulmonary pump, with no concurrent surgery or other cardiac pathologies. Factors like age, sex, weight, height, the duration of pump and cross-clamp, as well as other medical conditions including chronic obstructive pulmonary disease (COPD), diabetes mellitus (DM), opioid use, ejection fraction (EF), and creatinine clearance (CrCl) before the surgery were brought into consideration as possible confounders. The ratio of PiO2/FiO2 in the first hour after the surgery was measured, and its effect on intubation time and intensive care unit (ICU) length of stay was evaluated as the primary outcomes. The t-test and chi-squared were used to compare quantitative and qualitative variables, respectively. The repeated measures ANOVA test was used to compare the means. Results There was no significant relationship between hypoxemia measured as the ratio of PaO2/FiO2 and the duration of ICU length of stay (P value = 0.220) and the total intubation time (P value = 0.661). Among the qualitative variables, just opium addiction in patients with PaO2/FiO2 > 300 was associated with significantly longer intubation time (P value = 0.016). Furthermore, in the quantitative variables, longer intubation time was associated with higher cross-clamp time (P value = 0.035) in hypoxemia in the range of ARDS patients. Conclusions Hypoxemia after the CABG surgery is common and does not affect the short-term prognosis of CABG patients.

Prediction of Prolonged ICU Stay in Cardiac Surgery Patients as a Useful Method to Identify Nutrition Risk in Cardiac Surgery Patients: A Post Hoc Analysis of a Prospective Observational Study. JPEN J Parenter Enteral Nutr 2018; 43:768-779. [PMID: 30506711 PMCID: PMC7379574 DOI: 10.1002/jpen.1486] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Accepted: 10/22/2018] [Indexed: 12/30/2022]
Abstract
BACKGROUND Cardiovascular surgery patients with a prolonged intensive care unit (ICU) stay may benefit most from early nutrition support. Using established scoring systems for nutrition assessment and operative risk stratification, we aimed to develop a model to predict a prolonged ICU stay ≥5 days in order to identify patients who will benefit from early nutrition interventions. METHODS This is a retrospective analysis of a prospective observational study of patients undergoing elective valvular, coronary artery bypass grafting, or combined cardiac surgery. The nutrition risk was assessed by well-established screening tools. Patients' preoperative EuroSCORE (European System for Cardiac Operative Risk Evaluation), primary disease, and intraoperative cardiopulmonary bypass (CPB) time were included as independent variables in a multivariate logistic regression analysis to predict a prolonged ICU stay (>4 days). RESULTS The number of cardiac surgery patients included was 1193. Multivariate analysis revealed that for prediction of ICU stay >4 days, both Nutritional Risk Screening 2002 (area under the curve (AUC): 0.716, P = .020) and Mini Nutritional Assessment (MNA) score (AUC: 0.715, P = .037) were significant, whereas for prediction of ICU stay >5 days, only the MNA score showed significant results (AUC: 0.762, P = .011). CONCLUSION Present data provide first evidence about the combined use of EuroSCORE, primary disease, CPB time, and nutrition risk screening tools for prediction of prolonged ICU stay in cardiac surgery patients. If prospectively evaluated in adequately designed studies, this model may help to identify patients with prolonged ICU stay to initiate early postoperative nutrition therapy and thus, facilitate an enhanced recovery.

Abstract
Background There is no conclusive evidence for the effects of prolonged infusion of dexmedetomidine in critically ill patients. We aimed to investigate the safety of long-term dexmedetomidine infusion in a large critically ill patients cohort from the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC-III) database. Methods We retrospectively extracted records from MIMIC-III database. Dexmedetomidine administration time was the basis for group. Variables were compared by chi-square tests, and Mann-Whitney U test as appropriate. We used logistic regression model for multivariate analysis. Contour maps were drawn to measure rebound of heart rate (HR) and blood pressure (BP). Results We finally got 1,946 records including 1,368 distinct individuals. Age, body mass index (BMI), length of stay in hospital, accumulated doses of dexmedetomidine and Sequential Organ Failure Assessment (SOFA) score were independent risk factors of in-hospital mortality (P<0.05). But prolonged dexmedetomidine infusion (≥24 h) and abrupt cessation did not increase in-hospital mortality. Furthermore, the rebound of HR and BP was more likely to occur in patients with prolonged infusion of dexmedetomidine. Conclusions Prolonged dexmedetomidine infusion is not related to an increased in-hospital mortality, but it is associated with the rebound effect of HR and BP. Further prospective studies are needed.

Characteristics associated with prolonged length of stay after hysterectomy for benign gynecologic conditions. Am J Obstet Gynecol 2018; 219:89.e1-89.e15. [PMID: 29750957 DOI: 10.1016/j.ajog.2018.05.001] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Revised: 04/23/2018] [Accepted: 05/02/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Length of stay after surgery has become an important quality measure for many common surgical procedures and is now also tied to reimbursement. Currently, little is known about the perioperative factors that contribute to prolonged hospital length of stay in women who undergo hysterectomy for benign conditions. OBJECTIVE We performed a population-based analysis to investigate the association between perioperative factors and prolonged length of stay in women who undergo minimally invasive, abdominal, and vaginal hysterectomy. STUDY DESIGN We used the National Surgical Quality Improvement Program database to identify women from 2006-2015 who underwent benign hysterectomy. The primary outcome was length of stay >75th percentile. Demographic, preoperative, intraoperative, and postoperative factors were analyzed to determine individual predictors of prolonged length of stay. Model fit statistics were used to assess the importance of each group of perioperative factors on prolonged length of stay. RESULTS We identified a total of 157,589 women, including 83,172 (52.8%) of whom underwent minimally invasive hysterectomy, 45,149 (28.6%) of whom underwent abdominal hysterectomy, and 29,268 (18.6%) of whom underwent vaginal hysterectomy. The 75th percentile for length of stay was 1 day for minimally invasive, 3 days for abdominal, and 2 days for vaginal hysterectomy. The measured factors accounted for 11.0% of the ability to predict a prolonged length of stay for minimally invasive, 20.3% for abdominal, and 16.2% for vaginal hysterectomy. Intraoperative factors were the most important contributors to length of stay for minimally invasive and abdominal hysterectomy; demographic factors dominated for vaginal hysterectomy. CONCLUSION The most important perioperative factors that contributed to prolonged length of stay for hysterectomy were, in large part, not modifiable and suggest that targeted interventions to reduce length of stay will be challenging.

Abstract
OBJECTIVES To analyze patients after cardiac surgery that needed endotracheal reintubation and identify factors associated with death and its relation with the severity scores. METHODS Retrospective analysis of information of 1,640 patients in the postoperative period of cardiac surgery between 2007 and 2015. RESULTS The reintubation rate was 7.26%. Of those who were reintubated, 36 (30.3%) underwent coronary artery bypass surgery, 27 (22.7%) underwent valve replacement, 25 (21.0%) underwent correction of an aneurysm, and 8 (6.7%) underwent a heart transplant. Among those with comorbidities, 54 (51.9%) were hypertensive, 22 (21.2%) were diabetic, and 10 (9.6%) had lung diseases. Among those who had complications, 61 (52.6%) had pneumonia, 50 (42.4%) developed renal failure, and 49 (51.0%) had a moderate form of the transient disturbance of gas exchange. Noninvasive ventilation was performed in 53 (44.5%) patients. The death rate was 40.3%, and mortality was higher in the group that did not receive noninvasive ventilation before reintubation (53.5%). Within the reintubated patients who died, the SOFA and APACHE II values were 7.9 ± 3.0 and 16.9 ± 4.5, respectively. Most of the reintubated patients (47.5%) belonged to the high-risk group, EuroSCORE (> 6 points). CONCLUSION The reintubation rate was high, and it was related to worse SOFA, APACHE II and EuroSCORE scores. Mortality was higher in the group that did not receive noninvasive ventilation before reintubation.

Abstract
Introduction: Ventricular dysfunction requiring inotropic support frequently occurs after cardiac surgery, and the associated low cardiac output syndrome largely contributes to postoperative death. We aimed to study the incidence and potential risk factors of postcardiotomy ventricular dysfunction (PCVD) in moderate-to-high risk patients scheduled for open-heart surgery. Methods: Over a 5-year period, we prospectively enrolled 295 consecutive patients undergoing valve replacement for severe aortic stenosis or coronary artery bypass surgery who presented with Bernstein-Parsonnet scores >7. The primary outcome was the occurrence of PCVD as defined by the need for sustained inotropic drug support and by transesophageal echography. The secondary outcomes included in-hospital mortality and the incidence of any major adverse events as well as Intensive Care Unit (ICU) and hospital length of stay. Results: The incidence of PCVD was 28.4%. Patients with PCVD experienced higher in-hospital mortality (12.6% vs. 0.6% in patients without PCVD) with a higher incidence of cardiopulmonary and renal complications as well as a prolonged stay in ICU (median + 2 days). Myocardial infarct occurred more frequently in patients with PCVD than in those without PCVD (19 [30.2%] vs. 12 [7.6%]). By logistic regression analysis, we identified four independent predictors of PCVD: left ventricular ejection fraction <40% (odds ratio [OR] = 6.36; 95% confidence interval [CI], 2.59–15.60), age older than 75 years (OR = 3.35; 95% CI, 1.64–6.81), prolonged aortic clamping time (OR = 3.72; 95% CI, 1.66–8.36), and perioperative bleeding (OR = 2.33; 95% CI, 1.01–5.41). The infusion of glucose-insulin-potassium was associated with lower risk of PCVD (OR = 0.14; 95% CI, 0.06–0.33). Conclusions: This cohort study indicates that age, preoperative ventricular function, myocardial ischemic time, and perioperative bleeding are predictors of PCVD which is associated with poor clinical outcome.

Abstract
Objective Prolonged intensive care unit (ICU) stay prevents the use of ICU equipment by other patients and increases hospital cost. This retrospective study aimed to investigate the risk factors for prolonged ICU stay in patients undergoing open heart surgery. Methods The medical records of 513 patients who underwent coronary artery bypass grafting and valvular heart surgery were retrospectively evaluated. Patients were divided into two groups based on their ICU stay: groups I (<48 h) and II (≥48 h). The effect of patient variables on the ICU stay duration was investigated using logistic regression analysis. Results The mean age of the patients was 61.5±10 years, and 69% were males. The ICU stay of ≥48 h was observed in 20.1% of the patients. Diabetes mellitus and low ejection fraction (pre-operative variables); long aortic cross clamp, cardiopulmonary bypass time and intra-aortic balloon pump requirement (intra-operative variables); arrhythmia, myocardial infarction, renal dysfunction and need for haemodialysis, use of ≥2 inotropic agents, infection, sepsis and respiratory complication (post-operative variables) were found to prolong the ICU stay. In multivariate logistic regression analysis, intra-aortic balloon pump requirement, use of ≥2 inotropic agents, post-operative myocardial infarction and need for haemodialysis were found to be independent risk factors for prolonged ICU stay (p<0.05). Early mortality was 0.97% (5 patients). Conclusion Intra-aortic balloon pump requirement, use of ≥2 inotropic agents, post-operative myocardial infarction and need for post-operative haemodialysis are independent risk factors for patients undergoing open heart surgery. Selection of methods for protecting the myocardium and renal functions during the intra-operative period would reduce the duration of ICU stay.

Abstract
Objectives Accurate prediction of patients' length of stay is highly important. This study compared the performance of artificial neural network and adaptive neuro-fuzzy system algorithms to predict patients' length of stay in intensive care units (ICU) after cardiac surgery. Methods A cross-sectional, analytical, and applied study was conducted. The required data were collected from 311 cardiac patients admitted to intensive care units after surgery at three hospitals of Shiraz, Iran, through a non-random convenience sampling method during the second quarter of 2016. Following the initial processing of influential factors, models were created and evaluated. Results The results showed that the adaptive neuro-fuzzy algorithm (with mean squared error [MSE] = 7 and R = 0.88) resulted in the creation of a more precise model than the artificial neural network (with MSE = 21 and R = 0.60). Conclusions The adaptive neuro-fuzzy algorithm produces a more accurate model as it applies both the capabilities of a neural network architecture and experts' knowledge as a hybrid algorithm. It identifies nonlinear components, yielding remarkable results for prediction the length of stay, which is a useful calculation output to support ICU management, enabling higher quality of administration and cost reduction.

Abstract
Objective To characterize current vestibular schwannoma (VS) surgery outcomes with a nationwide database and identify factors associated with increased complications and prolonged hospital course. Study Design Retrospective review utilizing the University HealthSystem Consortium national inpatient database. Setting US academic health centers. Subjects and Methods Data from patients undergoing VS surgery were analyzed over a 3-year time span (October 2012 to September 2015). Surgical outcomes, such as length of stay (LOS), complications, and mortality, were analyzed on the basis of race, sex, age, and comorbidities during the 30-day postoperative period. Results A total of 3697 VS surgical cases were identified. The overall mortality rate was 0.38%, and the overall complication rate was 5.3%. Advanced age significantly affected intensive care unit LOS, mortality, and complications ( P = .04). Comorbidities, including hypertension, obesity, and depression, also significantly increased complication rates ( P = .02). Sixty-eight patients (1.8%) had a history of irradiation, and they had a significantly increased LOS ( P = .03). Conclusion Modern VS surgery has a low mortality rate and a relatively low rate of complications. Several factors contribute to high complication rates, including age and comorbidities. These data will help providers in counseling patients on which treatment course might be best suited for them.

Abstract
Background and aim Accurate prediction of prognosis of patients admitted to intensive care units (ICUs) is very important for the clinical management of the patients. The present study aims to identify independent factors affecting death and discharge in ICUs using competing risk modeling. Methods This retrospective cohort study was conducted on enrolling 880 patients admitted to emergency ICU in Namazi hospital, Shiraz University of Medical Sciences, Shiraz, Iran during 2013-2015. The data was collected from patients' medical records using a researcher-made checklist by a trained nurse. Competing risk regression models were fitted for the factors affecting the occurrence of death and discharge in ICU. Data analysis was conducted using STATA 13 and R 3.3.3 software. Results Among these patients, 682 (77.5%) were discharged and 157 (17.8%) died in the ICU. The patients' mean ± SD age was 48.90±19.52 yr. Among the study patients, 45.57% were female and 54.43% were male. In the competing risk model, age (Sub-distribution Hazard Ratio (SHR)) =1.02, 95% CI: 1.007-1.032), maximum heart rate (SHR=1.009, 95% CI: 1.001-1.019), minimum sodium level (SHR=1.035, 95% CI: 1.007-1.064), PH (SHR=7.982, 95% CI: 1.259-50.61), and bilirubin (SHR=1.046, 95% CI: 1.015-1.078) increased the risk of death, while maximum sodium level (SHR=0.946, 95% CI: 0.908-0.986) and maximum HCT (SHR=0.938, 95% CI: 0.882-0.998) reduced the risk of death. Conclusion In conclusion, the results of this study revealed several variables that were effective in ICU length of stay (LOS). The variables that independently influenced time-to-discharge were age, maximum systolic blood pressure, minimum HCT, maximum WBC, and urine output, maximum HCT and Glasgow coma score. The results also showed that age, maximum heart rate, maximum sodium level, PH, urine output, and bilirubin, minimum sodium level and maximum HCT were the predictors of death. Furthermore, our findings indicated that the competing risk model was more appropriate than the Cox model in evaluating the predictive factors associated with the occurrence of death and discharge in patients hospitalized in ICUs. Hence, this model could play an important role in managers' and clinicians' decision-making and improvement of the standard of care in ICUs.

Factors Affecting the Length of Stay in the Intensive Care Unit: Our Clinical Experience. BIOMED RESEARCH INTERNATIONAL 2018; 2018:9438046. [PMID: 29750174 PMCID: PMC5884409 DOI: 10.1155/2018/9438046] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Revised: 12/28/2017] [Accepted: 02/18/2018] [Indexed: 11/17/2022]
Abstract
Background and Aim Long hospital days in intensive care unit (ICU) due to life-threatening diseases are increasing in the world. The primary goal in ICU is to decrease length of stay in order to improve the quality of medical care and reduce cost. The aim of our study is to identify and categorize the factors associated with prolonged stays in ICU. Materials and Method We retrospectively analyzed 3925 patients. We obtained the patients' demographic, clinical, diagnostic, and physiologic variables; mortality; lengths of stay by examining the intensive care unit database records. Results The mean age of the study was 61.6 ± 18.9 years. The average length of stay in intensive care unit was 10.2 ± 25.2 days. The most common cause of hospitalization was because of multiple diseases (19.5%). The length of stay was positively correlated with urea, creatinine, and sodium. It was negatively correlated with uric acid and hematocrit levels. Length of stay was significantly higher in patients not operated on than in patients operated on (p < 0.001). Conclusion Our study showed a significantly increased length of stay in patients with cardiovascular system diseases, multiple diseases, nervous system diseases, and cerebrovascular diseases. Moreover we showed that when urea, creatinine, and sodium values increase, in parallel the length of stay increases.

Abstract
Background A prolonged stay in an intensive care unit (ICU) after cardiac surgery with cardiopulmonary bypass (CPB) increases the cost of care as well as morbidity and mortality. Several predictive models aim at identifying patients at risk of prolonged ICU stay after cardiac surgery with CPB, but almost all of them involve a preoperative assessment for proper resource management, while one - the Open-Heart Intraoperative Risk (OHIR) score - focuses on intra-operative manipulatable risk factors for improving anesthetic care and patient outcome. Objective We aimed to revalidate the OHIR score in a different context. Materials and methods The ability of the OHIR score to predict a prolonged ICU stay was assessed in 123 adults undergoing cardiac surgery (both coronary bypass graft and valvular surgery) with CPB at two tertiary university hospitals between January 2013 and December 2014. The criteria for a prolonged ICU stay matched a previous study (ie, a stay longer than the median). Results The area under the receiver operating characteristic curve of the OHIR score to predict a prolonged ICU stay was 0.95 (95% confidence interval 0.90-1.00). The respective sensitivity, specificity, positive predictive value, and accuracy of an OHIR score of ≥3 to discriminate a prolonged ICU stay was 93.10%, 98.46%, 98.18%, and 95.9%. Conclusion The OHIR score is highly predictive of a prolonged ICU stay among intraopera-tive patients undergoing cardiac surgery with CPB. The OHIR comprises of six risk factors, five of which are manipulatable intraoperatively. The OHIR can be used to identify patients at risk as well as to improve the outcome of those patients.

Abstract
PURPOSE Postoperative intensive care unit (ICU) stay after cardiac surgeries has been extensively studied, but little attention has been given to ICU stay following transcatheter aortic valve replacement (TAVR). This study examined ICU stay after TAVR. METHODS Two hundred and forty-five patients who underwent TAVR between April 2010 and October 2016 were studied retrospectively. We investigated the status of ICU stay, the predictors of prolonged ICU stay (PICUS), and its impact on short- and long-term outcomes. Prolonged ICU stay was defined as post-TAVR ICU stay longer than 2 days (day of TAVR + 1 day). RESULTS Length of ICU stay was 2.6 ± 4.9 days, and PICUS was identified in 14.7% of the patients. The predominant reason for PICUS was congestive heart failure or circulatory failure (41.7%). Pulmonary dysfunction and nontransfemoral approach were independent predictors of PICUS (pulmonary dysfunction: odds ratio = 2.64, 95% confidence interval [CI]: 1.05-7.35; nontransfemoral approach: odds ratio = 2.81, 95% CI: 1.15-6.89). Prolonged ICU stay was associated with higher rate of 30-day combined end point (PICUS vs non-PICUS: 44.4% vs 3.3%, P < .0001), longer postoperative hospital stay (49.9 ± 141.9 days vs 12.0 ± 6.0 days, P < .0001), and lower rate of discharge home (77.8% vs 95.2%, P = .0002). Patients with PICUS had worse long-term survival (P < .0001), and PICUS was a predictor of mortality (hazard ratio: 4.21, 95% CI: 2.09-8.22). CONCLUSION Prolonged ICU stay following TAVR was found in 14.7%, and pulmonary dysfunction and nontransfemoral approach were associated with PICUS. Short- and long-term prognoses were worse in patients with PICUS than those without.

Abstract
AIM Recently, hemogram parameters, such as mean platelet volume (MPV), had been proposed as novel inflammatory and prognostic factors. In present retrospective analysis, we aimed to determine and compare MPV of survived and dead patients whom admitted to intensive care unit (ICU) of our institution. METHODS We recorded hemogram parameters and other laboratory data and demographic characteristics of patients treated in ICU. Patients are divided into 2 groups-dead patients and survived patients. Laboratory data of survived patients compared to those of dead patients. RESULTS Age, gender, and other laboratory variables were not significantly different between dead and survived patients. On the other hand, MPV of survived patients was significantly higher than that of the dead patients ( P = .001). CONCLUSION We think that elevated MPV levels in an ICU patient should alert clinicians for worse outcome. Physicians should be more careful in the management of these patients.

Abstract
Over the past few years, there has been increased interest in data mining and machine learning methods to improve hospital performance, in particular hospitals want to improve their intensive care unit statistics by reducing the number of patients dying inside the intensive care unit. Research has focused on prediction of measurable outcomes, including risk of complications, mortality and length of hospital stay. The length of stay is an important metric both for healthcare providers and patients, influenced by numerous factors. In particular, the length of stay in critical care is of great significance, both to patient experience and the cost of care, and is influenced by factors specific to the highly complex environment of the intensive care unit. The length of stay is often used as a surrogate for other outcomes, where those outcomes cannot be measured; for example as a surrogate for hospital or intensive care unit mortality. The length of stay is also a parameter, which has been used to identify the severity of illnesses and healthcare resource utilisation. This paper examines a range of length of stay and mortality prediction applications in acute medicine and the critical care unit. It also focuses on the methods of analysing length of stay and mortality prediction. Moreover, the paper provides a classification and evaluation for the analytical methods of the length of stay and mortality prediction associated with a grouping of relevant research papers published in the years 1984 to 2016 related to the domain of survival analysis. In addition, the paper highlights some of the gaps and challenges of the domain.

Abstract
Background It is not clear whether performing continuous EEG (cEEG) in critically ill patients during intensive care unit (ICU) treatment affects outcomes at discharge. Material/Methods We prospectively matched 234 patients who received cEEG (cases) by admission diagnosis and sex to 234 patients who did not receive cEEG (controls) and followed them until discharge. Patients admitted due to seizures were excluded. The primary measures of outcome were Glasgow Coma Scale at Discharge (GCSD) and disposition at discharge, and the secondary measures of outcome were AED modifications, Glasgow Outcomes Scale, and Modified-Rankin Scale. These outcomes were compared between the cases and controls. Results Some differences in primary outcome measures between the groups emerged on univariate analyses, but these differences were small and not significant after controlling for covariates. Cases had longer ICU stays (p=0.002) and lower admission GCS (p=0.01) but similar GCSD (p=0.10). Of the secondary outcome measures, the mean (SD) number of AED modifications for cases was 2.2±3.1 compared to 0.4±0.8 for controls (p<0.0001); 170 (72.6%) cases had at least 1 AED modification compared to only 56 (24.1%) of the controls (p<0.0001). Conclusions Performing cEEG did not improve discharge outcome but it significantly influenced AED prescription patterns. Further studies assessing long-term outcomes are needed to better define the role of cEEG in this patient population.

Abstract
AIM The aim of our study was to identify predictors for prolonged ICU stay following elective adult cardiac surgery under cardiopulmonary bypass. PATIENTS AND METHODS A retrospective study was conducted during 5 years and a half period. Were included, patients age≥18 years old, underwent elective cardiac surgery under cardiopulmonary bypass. Patients who died within 48hours of surgery were excluded. Prolonged ICU stay was defined as stay in the ICU for 48hours or more. RESULTS During the review period, 610 patients were included. One hundred and sixty-four patients have required a prolonged ICU stay (26.9 %). In multivariate analysis, 5 predictors were identified: ejection fraction<30 % (OR 19.991, IC 95 % [1.382-289.1], P=0.028], pulmonary hypertension (OR 2.293, IC 95 % [1.058-4.973], P=0.036), prolonged ventilation (≥12hours) (OR 4.026, IC 95 % [2.407-6.733], P<0.001). Number of blood units transfused (OR 1.568, IC 95 % [1.073-2.291], and postoperative acute renal failure (OR 2.620, IC 95 % [1.026-6.690], P=0.044]. Prolonged ICU stay is significantly associated with prolonged hospital stay (17 days vs 13 days ; P<0.001) and higher in hospital mortality (22 % vs. 3 %, P<0.001). CONCLUSION The identification of these patients at risk of prolonged ICU stay is crucial. It will aid to plan prophylactic measures to optimize their support.

Abstract
Background Patients who have undergone cardiac surgery are generally mechanically ventilated postoperatively. Early postoperative extubation is currently recommended in anesthesia guidelines. No current technology can accurately, non-invasively, measure respiratory competence after extubation. Pulse oximetry has been helpful, but this is a late indicator of respiratory compromise. A novel, non-invasive, respiratory volume monitor (RVM) has been shown to deliver accurate continuous, real-time minute ventilation (MV), tidal volume (TV) and respiratory rate (RR) measurements and provide an objective measure of respiratory competence. The RVM will accurately reflect MV, TV and RR in cardiac surgery patients before and after extubation. Methods RVM traces were recorded from patients before and after cardiac surgery. Continuous monitoring began on admission to the unit and was ended at 24 h after extubation. RVM-based MV, TV and RR were calculated from 30-s segments. MV, TV and RR were also continuously recorded from the ventilator prior to extubation. The RVM was calibrated to each patient using the readings from the ventilator. Results During mechanical ventilation, the RVM measured TVs strongly correlated with the ventilator TVs (r = 0.97). Following extubation, the patient’s breathing became more erratic and TVs and MVs decreased. Within 1 h, all patients studied showed a marked recovery of MV and TV. Conclusions RVM-based MV, TV and RR correlated well with similar data collected from ventilators. After extubation, RVM shows promise as a means to monitor respiratory competence of non-intubated patients, and has implications for use in other settings and improving patient safety.

Abstract
BACKGROUND Intensive care unit (ICU) care is associated with costly and often scarce resources. In many parts of the world, ICUs are being perceived as major bottlenecks limiting downstream services such as operating theatres. There are many clinical, surgical and contextual factors that influence length of stay. Knowing these factors can facilitate resource planning. However, the extent at which this knowledge is put into practice remains unclear. The aim of this systematic review was to identify factors that impact the duration of ICU stay after cardiac surgery and to explore evidence on the link between understanding these factors and patient and resource management. METHODS We conducted electronic searches of Embase, PubMed, ISI Web of Knowledge, Medline and Google Scholar, and reference lists for eligible studies. RESULTS Twenty-nine papers fulfilled inclusion criteria. We recognised two types of objectives for identifying influential factors of ICU length of stay (LOS) among the reviewed studies. These were general descriptions of predictors and prediction of prolonged ICU stay through statistical models. Among studies with prediction models, only two studies have reported their implementation. Factors most commonly associated with increased ICU LOS included increased age, atrial fibrillation/ arrhythmia, chronic obstructive pulmonary disease (COPD), low ejection fraction, renal failure/ dysfunction and non-elective surgery status. CONCLUSION Cardiac ICUs are major bottlenecks in many hospitals around the world. Efforts to optimise resources should be linked to patient and surgical characteristics. More research is needed to integrate patient and surgical factors into ICU resource planning.
