UNASSIGNED: Early enteral nutrition (EN) is recommended for sepsis management, but its optimal timing and clinical benefits remain uncertain. This study evaluates whether early EN improves outcomes compared to delayed EN in patients with sepsis.
UNASSIGNED: We analyzed data of septic patients from the MIMIC-IV 2.2 database, focusing on those in the Medical Intensive Care Unit (MICU) and Surgical Intensive Care Unit (SICU). Patients who initiated EN within 3 days were classified into the early EN group, while those who started EN between 3 and 7 days were classified into the delayed EN group. Propensity score matching was used to compare outcomes between the groups.
UNASSIGNED: Among 1,111 patients, 786 (70.7%) were in the early EN group and 325 (29.3%) were in the delayed EN group. Before propensity score matching, the early EN group demonstrated lower mortality (crude OR = 0.694; 95% CI: 0.514-0.936; p = 0.018) and shorter ICU stays (8.3 [5.2, 12.3] vs. 10.0 [7.5, 14.2] days; p < 0.001). After matching, no significant difference in mortality was observed. However, the early EN group had shorter ICU stays (8.3 [5.2, 12.4] vs. 10.1 [7.5, 14.2] days; p < 0.001) and a lower incidence of AKI stage 3 (49.3% vs. 55.5%; p = 0.030). Subgroup analysis revealed that early EN significantly reduced the 28-day mortality rate in sepsis patients with lactate levels ≤4 mmol/L, with an adjusted odds ratio (aOR) of 0.579 (95% CI: 0.361, 0.930; p = 0.024).
UNASSIGNED: Early enteral nutrition may not significantly reduce overall mortality in sepsis patients but may shorten ICU stays and decrease the incidence of AKI stage 3. Further research is needed to identify specific patient characteristics that benefit most from early EN.

BACKGROUND: Nosocomial infections or hospital-acquired infections are a growing public health threat that increases patient morbidity and mortality. Patients at the highest risk are those in intensive care units. Therefore, our objective was to provide a pattern analysis of nosocomial infections that occurred in an adult surgical intensive care unit (ICU).
METHODS: This study was a retrospective observational study conducted in a 6-bed surgical intensive care unit (SICU) at An-Najah National University Hospital (NNUH) to detect the incidence of nosocomial infections from January 2020 until December 2021. The study group included 157 patients who received antibiotics during their stay in the SICU.
RESULTS: The incidence of nosocomial infections, either suspected or confirmed, in the SICU was 26.9% (95 out of 352 admitted patients). Pneumonia (36.8%) followed by skin and soft tissue infections (35.8%) were the most common causes. The most common causative microorganisms were in the following order: Pseudomonas aeruginosa (26.3%), Acinetobacter baumannii (25.3%), extended-spectrum beta lactamase (ESBL)-Escherichia coli (23.2%) and Klebsiella pneumonia (15.8%). The average hospital stay of patients with nosocomial infections in the SICU was 18.5 days.
CONCLUSIONS: The incidence of nosocomial infections is progressively increasing despite the current infection control measures, which accounts for an increased mortality rate among critically ill patients. The findings of this study may be beneficial in raising awareness to implement new strategies for the surveillance and prevention of hospital-acquired infections in Palestinian hospitals and health care centers.

BACKGROUND: The optimization of intensive care unit (ICU) care impacts clinical outcomes and resource utilization. In 2017, our surgical ICU (SICU) adopted a \"closed-collaborative\" model. The aim of this study is to compare patient outcomes in the closed-collaborative model versus the previous open model in a cohort of trauma surgical patients admitted to our adult level 1 trauma center.
METHODS: A retrospective review of trauma patients in the SICU from August 1, 2015 to July 31, 2019 was performed. Patients were divided into those admitted prior to August 1, 2017 (the \"open\" cohort) and those admitted after August 1, 2017 (the \"closed-collaborative\" cohort). Demographic variables and clinical outcomes were analyzed. Trauma severity was assessed using injury severity score (ISS).
RESULTS: We identified 1669 patients (O: 895; C: 774). While no differences in demographics were observed, the closed-collaborative cohort had a higher overall ISS (O: 21.5 ± 12.14; C: 25.10 ± 2.72; P < 0.0001). There were no significant differences between the two cohorts in the incidence of strokes (O: 1.90%; C: 2.58%, P = 0.3435), pulmonary embolism (O: 0.78%; C: 0.65%; P = 0.7427), sepsis (O: 5.25%; C: 7.49%; P = 0.0599), median ICU charges (O: $7784.50; C: $8986.53; P = 0.5286), mortality (O: 11.40%; C: 13.18%; P = 0.2678), or ICU length of stay (LOS) (O: 4.85 ± 6.23; C: 4.37 ± 4.94; P = 0.0795).
CONCLUSIONS: Patients in the closed-collaborative cohort had similar clinical outcomes despite having a sicker cohort of patients. We hypothesize that the closed-collaborative ICU model was able to maintain equivalent outcomes due to the dedicated multidisciplinary critical care team caring for these patients. Further research is warranted to determine the optimal model of ICU care for trauma patients.

Background Fenoldopam is a short-acting dopamine A1 receptor agonist which mediates vasodilation of the renal arteries, thereby increasing urine output. The objective of this study was to compare the effects of fenoldopam and its synergistic effect on furosemide for improving the urine output in postoperative critically ill patients with acute kidney injury (AKI). Methods This is a retrospective study of postoperative critically ill patients with AKI. Patients who received furosemide (control group) were compared with those who received furosemide plus fenoldopam (treatment group) and evaluated at 12 and 24 hours post-treatment. Patients with oliguria and AKI were included in the study, while patients with chronic kidney disease (CKD) were excluded. Glomerular filtration rate, serum creatinine, blood pressure, calculated fluid accumulation, fluid intake, urine output, and total fluid output were used as variables to assess the medication effect. Results Of the 126 patients who met the inclusion and exclusion criteria, 87 patients received furosemide alone, and 39 patients received furosemide plus fenoldopam during their first 24 hours of admission to the surgical intensive care unit (SICU). Although not statistically significant, the addition of fenoldopam demonstrated an increase in mean urine output of 1525ml (IQR; 1530-2095) in the first 24 hours (P=0.06). There was also noted an increase in the urine output (p= 0.07) and a decrease in the total fluid accumulation when fenoldopam was co-administered with furosemide when compared to the patients who were only treated with furosemide (p=0.06). There was no significant change in creatinine clearance from baseline in either group.  Conclusion Fenoldopam may increase urine output in postoperative critically ill patients with acute kidney injury when administered within the first 24 hours of presentation. Based on our results, fenoldopam appears to have a synergistic effect with furosemide in our study population.

Abstract Background: Clostridioides difficile infection (CDI) is a common and sometimes life-threatening illness. Patient-, care-, and room hygiene-specific factors are known to impact CDI genesis, but care provider training and room topography have not been explored. We sought to determine if care in specific intensive care unit (ICU) rooms asymmetrically harbored CDI cases. Patients and Methods: Surgical intensive care unit (SICU) patients developing CDI (July 2009 to June 2018) were identified and separated by service (green/gold). Each service cared for their respective 12 rooms, otherwise differing only in resident team composition (July 2009 to August 2017: green, anesthesia; gold, surgery; August 2017 to June 2018: mixed for both). Fixed/mobile room features and provider traffic in three room zones (far/middle/near in relation to the toilet) were compared between high-/low-incidence rooms using observation via telecritical care video cameras. Results: Seventy-four new CDI cases occurred in 7,834 consecutive SICU admissions. In period one, green CDI cases were almost double gold cases (39 vs. 21; p = 0.02) but were similar in period two in which trainee service allocation intermixed. High-incidence rooms had closer toilet-to-intravenous pole proximity than low-incidence rooms (7.7 + 1.8 feet vs. 3.9 + 1.5 feet; p = 0.02). High-incidence rooms consistently housed mobile objects (patient bed, table-on-wheels) farther away from the toilet. Although physician time spent in each zone was similar, nurses spending more than 15 minutes in-room more frequently stayed in the far/middle zones in high-incidence rooms. Conclusions: Distinct SICU room features relative to toilet location and bedside clinician behaviors interact to alter patient CDI acquisition risk. This suggests that CDI risk occurs as a structural aspect of ICU care, offering the potential to reduce patient risk through deliberate room redesign.

UNASSIGNED: Activity-based costing (ABC) is a costing technique that identifies the activities in an organization and assigns the cost to the activities based on the actual resources consumed for each activity. The method was used to ascertain the cost of surgical intensive care unit (SICU) bed in an institute of national importance, such as All India Institute of Medical Sciences (AIIMS), Bhubaneswar, from June 2019 to February 2021.
UNASSIGNED: The present study aimed to ascertain the cost of SICU beds per day by the ABC technique. The different elements of cost were analyzed. The cost for selected patients in the SICU unit was calculated by preparing a cost sheet based on the elements of cost and studying the existing charging system.
UNASSIGNED: A total of 38 cases were selected from the departments of General Surgery, Urology, Orthopedics, and Plastic surgery. Based on the ABC technique, the activity map was developed for SICU (cost center), and the time consumed together with resources for each activity was calculated with respect to human resources, consumables, medicines, and overheads. Thus, the total cost incurred by the hospital for SICU beds per day was estimated using the cost sheet analysis.
UNASSIGNED: The cost was calculated to be Rs. 11,241/- per day (155 USD) against the hospital charge of Rs. 35/- (<0.5 USD) for general patients and Rs. 1000/- for private ward patients. Exchange Conversion Rate used is 1 USD = 72.60 INR (2020-21).
UNASSIGNED: The public sector hospitals in India provide health-care services for free and at a subsidized rate; hence, ascertaining the cost incurred by the hospital is necessary for policy decisions.

Surgical intensive care units (SICU) require complex care from a multi-disciplinary team. Frequent changes in team members can lead to shifting expectations for junior general surgical trainees, which creates a challenging working and learning environment. We aim to identify expectations of junior surgery trainee\'s medical knowledge and technical/non-technical skills at the start of their SICU rotation. We hypothesize that expectations will not be consistent across SICU stakeholder groups.
Twenty-eight individual semi-structured interviews were conducted with six SICU stakeholder groups at a medium-sized academic hospital. Expectations were identified from interview transcripts. Frequency counts were analyzed.
Forty-one expectations were identified. 4 expectations were identified by a majority of interviewees. Most expectations were identified by 7 or fewer interviewees. 23 (53%) expectations were shared by at least one stakeholder group. 2 (8%) expectations were shared by all groups.
SICU stakeholder groups identified ten medical knowledge, ten technical skill, and three non-technical skill expectations. Yet, few expectations were shared among the groups. Thus, SICU stakeholder groups have disparate expectations for surgery trainees in our SICU.

Untreated pain and pain management with opioids are independent precipitating factors for delirium. This retrospective study evaluated the relationships among pain severity, its management with opioids, and the onset of delirium in older adult patients admitted to the surgical intensive care unit (SICU). Consecutive patients aged 65 or greater admitted to the SICU over a 5-month period were examined (n = 172). When assessed using a multivariable general estimating equation model, opioids (chi-square [χ2], 12.34, p = .0004), but not pain (χ2, 3.31, p = .0688) were significant in predicting next-day delirium status. Controlling for pain, patients exposed to opioids were 2.5 times more likely to develop delirium than patients not exposed (95% Confidence Interval: 1.44-4.36). Our data shows that opioid administration predicted the onset of next-day delirium. In an effort to prevent delirium, future research should focus on opioid-sparing pain management approaches to mitigate pain and delirium.

Simulation-based education can augment residents\' skills and knowledge. We assessed the effectiveness of a simulation-based course for surgery interns designed to improve their comfort, knowledge, and ability to manage common surgical critical care (SCC) conditions.
For 2 y, all first year residents (n = 31) in general surgery, urology, interventional radiology, and the integrated plastics, vascular, and cardiothoracic surgery training programs at our institution participated in a simulation-based course emphasizing evidence-based management of SCC conditions. Precourse and postcourse surveys and multiple-choice tests, as well as summative simulation tests, assessed interns\' comfort, knowledge, and ability to manage SCC conditions. Changes in these measures were assessed with Wilcoxon matched-pairs signed rank tests. Factors associated with summative performance were determined by linear regression.
The course consisted of four simulation-based teaching sessions in year 1 and six in year 2. The course taught seven of the 18 core SCC conditions in the Surgical Council on Resident Education general surgery curriculum in year 1 and 10 in year 2. Interns\' self-reported comfort, knowledge, and ability to manage each condition taught in the course increased (P < 0.02). Their knowledge of each condition, as assessed by written tests, also increased (P < 0.02). Their summative simulation test performance correlated with the number of course sessions attended (P < 0.03) and status as general surgery residents (P < 0.01).
A simulation-based SCC training course for surgery interns that emphasizes evidence-based management of SCC conditions improves interns\' comfort, knowledge, and ability to manage these conditions.

Delirium is prevalent in hospitalized older adults. Little is known about delirium among older adults admitted to the surgical intensive care unit (SICU).
The purpose of this study was to describe the incidence of delirium, length of stay, 30-day readmission and mortality rates experienced by older adults in the SICU before and after a nurse-driven protocol for delirium-informed care.
This study employed a retrospective observational cohort design. Consecutive patients 65 years or older admitted to the SICU over six-month periods were compared before (n = 101) and following (n = 172) a nurse-driven protocol for delirium-informed care. Patient-level outcomes included incidence delirium, SICU and hospital length of stay, 30-day readmission and mortality rates. All measures were collected using medical record review.
In the pre- and post-intervention cohorts, 37% (37/101) and 33% (56/172) of patients screened positive for delirium, respectively. Following implementation of the delirium-informed care intervention, the number of days where no CAM-ICU assessment was performed significantly decreased (Pre 1.1 ± 1.4; Post 0.45 ± 0.65; p <0.001) and the number of negative assessments significantly increased (Pre 2.45 ± 1.66; Post 2.94 ± 1.69; p < 0.0178), indicating that nurses post-intervention were more consistently assessing for delirium.
This study failed to show improvements in patient outcomes (SICU and hospital length of stay, 30-day readmission and mortality rates), before and following a delirium-informed care intervention. However, positive trends in the data suggest that delirium-informed care has the potential to increase rates of assessment and delirium identification, thereby providing the foundation for reducing the consequences of delirium and improve patient-level outcomes. Further better controlled prospective work is needed to validate this intervention.
