Assessment of soluble thrombomodulin and soluble endoglin as endothelial dysfunction biomarkers in seriously ill surgical septic patients: correlation with organ dysfunction and disease severity.

BACKGROUND: Sepsis, a complex condition characterized by dysregulated immune response and organ dysfunction, is a leading cause of mortality in ICU patients. Current diagnostic and prognostic approaches primarily rely on non-specific biomarkers and illness severity scores, despite early endothelial activation being a key feature of sepsis. This study aimed to evaluate the levels of soluble thrombomodulin and soluble endoglin in seriously ill surgical septic patients and explore their association with organ dysfunction and disease severity. METHODOLOGY: A case control study was conducted from March 2022 to November 2022, involving seriously ill septic surgical patients. Baseline clinical and laboratory data were collected within 24 h of admission to the Surgical Intensive Care Unit. This included information such as age, sex, hemodynamic parameters, blood chemistry, SOFA score, qSOFA score, and APACHE-II score. A proforma was filled out to record these details. The outcome of each patient was noted at the time of discharge. RESULTS: The study found significantly elevated levels of soluble thrombomodulin and soluble endoglin in seriously ill surgical septic patients. The RTqPCR analysis revealed a positive correlation between soluble thrombomodulin and soluble endoglin levels with the qSOFA score, as well as, there was a positive association between RTqPCR soluble thrombomodulin and the SOFA score. These findings indicate a correlation between these biomarkers and organ dysfunction and disease severity. CONCLUSION: The study concludes that elevated levels of soluble thrombomodulin and soluble endoglin can serve as endothelial biomarkers for early diagnosis and prognostication in seriously ill surgical septic patients.

Result of the implementation of a quality management system based on the ISO 9001:2015 standard in a surgical intensive care unit.

INTRODUCTION: The implementation of Quality Management Systems (QMS) is one of the fundamental and future-oriented elements for the improvement of modern health systems. The objective of implementing a QMS in accordance with the requirements of the ISO 9001: 2015 Standard is to effectively carry out its activities, covering both technical and management aspects, guaranteeing the satisfaction of the needs and expectations of all its stakeholders, as well as compliance with legal and regulatory requirements. It must contemplate all those aspects that have an impact on the final quality of the product or service provided by the organization. OBJECTIVE: The main objective is to describe the process of implementing a QMS under the ISO 9001: 2015 Standard in the Surgical Intensive Care Unit of the General University Hospital of Elche and evaluate its results. METHODOLOGY: Carrying out and implementing a QMS in the Surgical Intensive Care Unit of the General University Hospital of Elche applying the points of the ISO 9001: 2015 Standard. The SGC has followed the benchmark of management by processes, identifying from its strategic core of mission, vision and values, the different processes involved and their interrelation reflected in the process map. Based on it, the necessary documents have been developed to describe the operation of the Unit both at an operational level through the key processes (admission and initial assessment of the patient, stabilization, follow-up, complementary tests, interconsultations, transfers and discharge) as well as which refers to procedures of a strategic or support type. RESULTS: The strategic lines that marked the beginning of the deployment of our QMS were defined with the drafting of 7 objectives, achieving 100% compliance. The key processes (7) that described the functioning of our organization were elaborated, as well as those of a strategic type (14) and support or support (5), complemented with 55 medical and nursing protocols. 20 monitoring indicators were analyzed: 6 organizational and planning type, and 14 clinical. 46 incidents were detected in the first year of implementation of the QMS that were analyzed by the Quality Commission, emerging 7 corrective actions. 14 improvement actions were developed after the application of the AMFE methodology for key processes, achieving an average of greater than 70% effectiveness after reassessment. From the analysis of patient and family satisfaction through SAIP case management, 41 of a total of 52 cases were acknowledgments in writing. CONCLUSIONS: Implementing a QMS in our Surgical Intensive Care Unit has made it possible to define the strategic lines of our organization, develop objectives, establish monitoring indicators, standardize the work of the Unit through procedures and protocols, increase safety at work through the use of lists of verification, initiate improvement actions to strengthen the weak points of the QMS itself, as well as know the degree of satisfaction and needs of our patients and the personnel who work in it.

Management of Common Postoperative Infections in the Surgical Intensive Care Unit.

Postoperative infection and sepsis in the surgical intensive care unit (SICU) are common problems, and can be the reason for SICU admission or can be acquired during the SICU stay. Both diagnosis and management of infection and sepsis in the SICU can be complex, related to the surgical procedures performed, patient comorbidities, and resistant pathogens. The need for "source control" of postoperative infections can pose specific challenges and significant complexity in patient management. Postoperative infections in the SICU are associated with increased morbidity, mortality, and resource utilization, and therefore a strong focus on infection preventive strategies is warranted.

Machine learning for infection risk prediction in postoperative patients with non-mechanical ventilation and intravenous neurotargeted drugs.

Drug efficacy can be improved by understanding the effects of anesthesia on the neurovascular system. In this study, we used machine learning algorithms to predict the risk of infection in postoperative intensive care unit (ICU) patients who are on non-mechanical ventilation and are receiving hydromorphone analgesia. In this retrospective study, 130 patients were divided into high and low dose groups of hydromorphone analgesic pump patients admitted after surgery. The white blood cells (WBC) count and incidence rate of infection was significantly higher in the high hydromorphone dosage group compared to the low hydromorphone dosage groups (p < 0.05). Furthermore, significant differences in age (P = 0.006), body mass index (BMI) (P = 0.001), WBC count (P = 0.019), C-reactive protein (CRP) (P = 0.038), hydromorphone dosage (P = 0.014), and biological sex (P = 0.024) were seen between the infected and non-infected groups. The infected group also had a longer hospital stay and an extended stay in the intensive care unit compared to the non-infected group. We identified important risk factors for the development of postoperative infections by using machine learning algorithms, including hydromorphone dosage, age, biological sex, BMI, and WBC count. Logistic regression analysis was applied to incorporate these variables to construct infection prediction models and nomograms. The area under curves (AUC) of the model were 0.835, 0.747, and 0.818 in the training group, validation group, and overall pairwise column group, respectively. Therefore, we determined that hydromorphone dosage, age, biological sex, BMI, WBC count, and CRP are significant risk factors in developing postoperative infections.

The Use of Critical Care Services After Orthopedic Surgery at a High-Volume Orthopedic Medical Center: A Retrospective Study.

Background: With an aging population, orthopedics has become one of the largest and fastest growing surgical fields. However, data on the use of critical care services (CCS) in patients undergoing orthopedic procedures remain sparse. Purpose: We sought to elucidate the prevalence and characteristics of patients requiring CCS and intermediate levels of care after orthopedic surgeries at a high-volume orthopedic medical center. Methods: We retrospectively reviewed inpatient electronic medical record data (2016-2020) at a high-volume orthopedic hospital. Patients who required CCS and intermediate levels of care, including step-down unit (SDU) and telemetry services, were identified. We described characteristics related to patients, procedures, and outcomes, including type of advanced services required and surgery type. Results: Of the 50,387 patients who underwent orthopedic inpatient surgery, 1.6% required CCS and 21.6% were admitted to an SDU. Additionally, 482 (1.0%) patients required postoperative mechanical ventilation and 3602 (7.1%) patients required continuous positive airway pressure therapy. Spine surgery patients were the most likely to require any form of advanced care (45.7%). Conclusions: This retrospective review found that approximately one-fourth of orthopedic surgery patients were admitted to units that provided critical and intermediate levels of care. These results may prove useful to hospitals in estimating needs and allocating resources for advanced and critical care services after orthopedic surgery.

Opioid Prescribing Behaviors Among Surgical Intensive Care Unit Attending Physicians.

BACKGROUND: More than 5 million Americans misuse opioids. Six percent of patients who receive opioids for acute pain progress to chronic use; this increases with higher doses and longer prescriptions. Prescribing variation exists within trauma centers and after emergency surgery but has not been demonstrated among intensivists. METHODS: Milligram morphine equivalents (MME) per patient-ICU-day provided by eleven surgical intensivists were analyzed. The patients were separated into 2 groups based on their percentage of time intubated in the surgical ICU. Both study groups were compared using demographics and comorbidity scores. The attendings were divided into high- and low-prescribing groups based on their MME/pt-ICU-day for intubated patients, and bivariate statistical analyses were performed. A similar analysis compared surgery vs anesthesia intensivists. RESULTS: The analysis included 257 patients in the "long-vent group" (LVG) and 668 patients in the "short-vent group" (SVG). The average MME/pt-ICU-day for the LVG was 222. Despite no significant differences in age, sex, or Elixhauser Comorbidity Index, there was a 45% difference between the high- and low-prescribing physicians in the LVG (253.7 vs 175.4 MME/pt-ICU-day; P = .008). This difference was not observed for patients in the SVG (74.3 vs 93.1 MME/pt-ICU-day; P = .141) nor based on intensivist specialty (LVG: 217.9 vs 209.5 MME/pt-ICU-day; P = .8) (SVG: 79.0 vs 93.3 MME/pt-ICU-day; P = .288).

Early feeding after percutaneous endoscopic gastrostomy tube placement in patients who require trauma and surgical intensive care: A retrospective cohort study.

BACKGROUND: Critically ill patients experience interruptions in enteral nutrition (EN). For ventilated patients who undergo percutaneous endoscopic gastrostomy (PEG) tube placement, postprocedure fasting times vary from 1 to 24 h depending on the surgeon's preference. There is no evidence to support delayed feeding (DF) after PEG placement. This study's purpose was to determine if there is an increased complication rate associated with early feeding (EF) after PEG. METHODS: 150 adult ventilated patients in the trauma and surgical intensive care unit (TSICU) at a level I trauma center underwent PEG placement in March 2015 through May 2018 by one of six surgical intensivists. Retrospective review revealed variable post-PEG fasting practices: one started EN at 1 h, two started at 4 h, two started at 6 h, and one started at 24 h. Time to initiation of EN and complication rates were assessed. Patients were divided into EF (<4) and DF (≥4 h) groups. RESULTS: Median postprocedure fasting time was 5.5 h. The overall complication rate was 3.3%, with a feeding intolerance rate of 0.7% and aspiration rate of 0%. There was no difference in complication rate for EF (3.1%) as compared with DF (3.4%) (odds ratio, 0.92; 95% CI, 0.10-8.52; P = 0.7). CONCLUSION: Complication rates following PEG placement in ventilated TSICU patients are low and do not change with EF compared with DF. EF is probably safe.

Antibiotic Therapy in the Intensive Care Unit.

Antibiotic resistance is a public health concern. A critical care clinician is faced with a clinical dilemma of using the appropriate treatment without compromising the antibiotic armamentarium. Postoperative and trauma patients in the intensive care unit (ICU) pose a unique challenge of mounting a systemic inflammatory response, which makes it even more difficult to differentiate inflammation from infection. The decision for type of empirical therapy should be individualized to the patient and local ecology data and resistance profiles. After initiation of empirical therapy, deescalation should be done once microbiology data are available. Antibiotic stewardship programs are essential in the ICU.

[Glutamine as a component of nutritional and metabolic therapy for surgical patients in ICU]. / Glutamin kak komponent nutritivno-metabolicheskoi terapii patsientov khirurgicheskogo profilya v usloviyakh ORIT.

Glutamine is the most abundant amino acid in the human body that is involved in various metabolic processes. The development of hypermetabolic and hypercatabolic syndrome that accompanies critical conditions of ICU patients is associated with a decrease in the concentration of glutamine, especially in the blood plasma and muscles. This process may last for quite a long time and lead to a number of complications up to a fatal outcome. This review was aimed to analyze clinical studies conducted over the past 20 years that demonstrate the effect of intravenous infusion of glutamine dipeptide as part of balanced parenteral nutrition on the perioperative period: the severity of inflammatory response; the state of the intestinal mucosa; the incidence and severity of complications; mortality; the duration of stay in the ICU and hospital in general, etc. The analysis was performed using systematic reviews and meta-analyses based on randomized double-blind, placebo-controlled trials in different countries selected in the main databases (PubMed, EMBASE, Web of Science, The Cochrane Library, etc.). Most of the reports state that the inclusion of glutamine dipeptide in nutritional and metabolic therapy (NMT) in surgical patients reduces the frequency and severity of infectious complications and mortality, reduces the length of stay in ICU and in hospital in general, improves the biochemical parameters that reflect the condition of patients, and reduces the treatment costs. Thus, the conducted systematic reviews and meta-analyses confirm that the use of the parenteral form of glutamine dipeptide (Dipeptiven 20%) as part of balanced standard parenteral nutrition (PN) is a clinically and pharmacoeconomically justified strategy of NMT in surgical ICU patients.

Transfer Status and 90-Day Mortality in Intensive Care Unit Patients With Sepsis: A Propensity Matched Analysis.

BACKGROUND: Timely identification and management of sepsis in surgical patients is crucial, and transfer status may delay optimal treatment of these patients. The objective of this study was to compare in-house and 90-day mortality between patients primarily admitted or transferred into the surgical ICU (SICU) at a tertiary referral center. MATERIAL AND METHODS: All patients admitted to the SICU with a diagnosis of sepsis (Sepsis III) were reviewed at a single institution between 2014 to 2019 (n = 1489). Demographics, comorbidities, and sepsis presentation were compared between transferred (n = 696) and primary patients (n = 793). Primary outcomes evaluated were in-house and 90 day mortality in an unmatched and propensity score matched cohorts. A P value < 0.05 was considered statistically significant. RESULTS: Transfer patients were more likely to have obesity (60% versus 49%, P < 0.005), a higher median SOFA (6 (4-8) versus 5 (3-8), P = 0.007), and require vasopressors on admission (42% versus 35%, P = 0.004). Compared to primary patients, transfer patients exhibited higher rates of respiratory failure (76% versus 69%, P = 0.003), in-house (30% versus 17%, P < 0.005), and 90 day mortality (36% versus 24%, P < 0.005). After matching, transferred patients were associated with 75% and 83% increased odds of in-house and 90 day mortality after controlling for age, sex, race, comorbidities, BMI, and sepsis severity. CONCLUSIONS: Transfer status is associated with an over 80% increase in the odds of 90 day mortality for patients admitted to the SICU with sepsis. Aggressive patient identification and earlier transfer of those at higher risk of death may reduce this effect.

An antibiotic stewardship program in a surgical ICU of a resource-limited country: financial impact with improved clinical outcomes.

BACKGROUND: Antibiotic resistance (ABX-R) is alarming in lower/middle-income countries (LMICs). Nonadherence to antibiotic guidelines and inappropriate prescribing are significant contributing factors to ABX-R. This study determined the clinical and economic impacts of antibiotic stewardship program (ASP) in surgical intensive care units (SICU) of LMIC. METHOD: We conducted this pre and post-test analysis in adult SICU of Aga Khan University Hospital, Pakistan, and compared pre-ASP (September-December 2017) and post-ASP data (April-July 2018). January-March 2018 as an implementation/training phase, for designing standard operating procedures and training the team. We enrolled all the patients admitted to adult SICU and prescribed any antibiotic. ASP-team daily reviewed antibiotics prescription for its appropriateness. Through prospective-audit and feedback-mechanism changes were made and recorded. Outcome measures included antibiotic defined daily dose (DDDs)/1000 patient-days, prescription appropriateness, antibiotic duration, readmission, mortality, and cost-effectiveness. RESULT: 123 and 125 patients were enrolled in pre-ASP and post-ASP periods. DDDs/1000 patient-days of all the antibiotics reduced in the post-ASP period, ceftriaxone, cefazolin, metronidazole, piperacillin/tazobactam, and vancomycin showed statistically significant (p < 0.01) reduction. The duration of all antibiotics use reduced significantly (p < 0.01). Length of SICU stays, mortality, and readmission reduced in the post-ASP period. ID-pharmacist interventions and source-control-documentation were observed in 62% and 50% cases respectively. Guidelines adherence improved significantly (p < 0.01). Net cost saving is 6360US$ yearly, mainly through reduced antibiotics consumption, around US$ 18,000 (PKR 2.8 million) yearly. CONCLUSION: ASP implementation with supplemental efforts can improve the appropriateness of antibiotic prescriptions and the optimum duration of use. The approach is cost-effective mainly due to the reduced cost of antibiotics with rational use. Better source-control-documentation may further minimize the ABX-R in SICU.

Anaemia requiring red blood cell transfusion is associated with unfavourable 90-day survival in surgical patients with sepsis.

OBJECTIVE: The mortality associated with sepsis remains unacceptably high, despite modern high-quality intensive care. Based on the results from previous studies, anaemia and its management in patients with sepsis appear to impact outcomes; however, the transfusion policy is still being debated, and the ideal approach may be extremely specific to the individual. This study aimed to investigate the long-term impact of anaemia requiring red blood cell (RBC) transfusion on mortality and disease severity in patients with sepsis. We studied a general surgical intensive care unit (ICU) population, excluding cardiac surgery patients. 435 patients were enrolled in this observational study between 2012 and 2016. RESULTS: Patients who received RBC transfusion between 28 days before and 28 days after the development of sepsis (n = 302) exhibited a significantly higher 90-day mortality rate (34.1% vs 19.6%; P = 0.004, Kaplan-Meier analysis). This association remained significant after adjusting for confounders in the multivariate Cox regression analysis (hazard ratio 1.68; 95% confidence interval 1.03-2.73; P = 0.035). Patients who received transfusions also showed significantly higher morbidity scores, such as SOFA scores, and ICU lengths of stay compared to patients without transfusions (n = 133). Our results indicate that anaemia and RBC transfusion are associated with unfavourable outcomes in patients with sepsis.

A combination of SOFA score and biomarkers gives a better prediction of septic AKI and in-hospital mortality in critically ill surgical patients: a pilot study.

Background: Sepsis is a syndrome characterized by a constellation of clinical manifestations and a significantly high mortality rate in the surgical intensive care unit (ICU). It is frequently complicated by acute kidney injury (AKI), which, in turn, increases the risk of mortality. Therefore, it is of paramount importance to identify those septic patients at risk for the development of AKI and mortality. The objective of this pilot study was to evaluate several different biomarkers, including NGAL, calprotectin, KIM-1, cystatin C, and GDF-15, along with SOFA scores, in predicting the development of septic AKI and associated in-hospital mortality in critically ill surgical patients. Methods: Patients admitted to the surgical ICU were prospectively enrolled, having given signed informed consent. Their blood and urine samples were obtained and subjected to enzyme-linked immunosorbent assay (ELISA) to determine the levels of various novel biomarkers. The clinical data and survival outcome were recorded and analyzed. Results: A total of 33 patients were enrolled in the study. Most patients received surgery prior to ICU admission, with abdominal surgery being the most common type of procedure (27 patients (81.8%)). In the study, 22 patients had a diagnosis of sepsis with varying degrees of AKI, while the remaining 11 were free of sepsis. Statistical analysis demonstrated that in patients with septic AKI versus those without, the following were significantly higher: serum NGAL (447.5 ± 35.7 ng/mL vs. 256.5 ± 31.8 ng/mL, P value 0.001), calprotectin (1030.3 ± 298.6 pg/mL vs. 248.1 ± 210.7 pg/mL, P value 0.049), urinary NGAL (434.2 ± 31.5 ng/mL vs. 208.3 ± 39.5 ng/mL, P value < 0.001), and SOFA score (11.5 ± 1.2 vs. 4.4 ± 0.5, P value < 0.001). On the other hand, serum NGAL (428.2 ± 32.3 ng/mL vs. 300.4 ± 44.3 ng/mL, P value 0.029) and urinary NGAL (422.3 ± 33.7 ng/mL vs. 230.8 ± 42.2 ng/mL, P value 0.001), together with SOFA scores (10.6 ± 1.4 vs. 5.6 ± 0.8, P value 0.003), were statistically higher in cases of in-hospital mortality. A combination of serum NGAL, urinary NGAL, and SOFA scores could predict in-hospital mortality with an AUROC of 0.911. Conclusions: This pilot study demonstrated a promising panel that allows an early diagnosis, high sensitivity, and specificity and a prognostic value for septic AKI and in-hospital mortality in surgical ICU. Further study is warranted to validate our findings.

Extubation to high-flow nasal cannula in critically ill surgical patients.

BACKGROUND: High-flow nasal cannula (HFNC) is increasingly used to reduce reintubations in patients with respiratory failure. Benefits include providing positive end expiratory pressure, reducing anatomical dead space, and decreasing work of breathing. We sought to compare outcomes of critically ill surgical patients extubated to HFNC versus conventional therapy. METHODS: A retrospective review was conducted in the surgical intensive care unit of an academic center during August 2015 to February 2016. Data including demographics, ventilator days, oxygen therapy after extubation, reintubation rates, surgical intensive care unit and hospital length of stay, and mortality were collected. Self and palliative extubations were excluded. Characteristics and outcomes, with the primary outcome being reintubation, were compared between those extubated to HFNC versus cool mist/nasal cannula (CM/NC). RESULTS: Of the 184 patients analyzed, 46 were extubated to HFNC and 138 to CM/NC. Mean age and days on ventilation before extubation were 57.8 years and 4.3 days, respectively. Both cohorts were similar in age, sex, and had a similar prevalence of cardiopulmonary diagnoses at admission. Although prior to extubation HFNC had lengthier ventilation requirements (7.1 versus 3.4 days, P < 0.01) and ICU stays (7.8 versus 4.1 days, P < 0.01), the rate of reintubation was similar to CM/NC (6.5% versus 13.8%, P = 0.19). Multivariable analysis demonstrated HFNC to be associated with a lower risk of reintubation (adjusted odds ratio = 0.15, P = 0.02). Mortality rates were similar. CONCLUSIONS: Ventilated patients at risk for recurrent respiratory failure have reduced reintubation rates when extubated to HFNC. Patients with prolonged intubation or those with high-risk comorbidities may benefit from extubation to HFNC.

Risk factors for colonization by carbapenemase-producing enterobacteria at admission to a Surgical ICU: A retrospective study.

INTRODUCTION: In 2011, a hospital-wide outbreak of OXA-48 producing Klebsiella pneumoniae occurred in our hospital, an epidemiological setting of high ESBL-producing K. pneumoniae rates. This study identifies risk factors for colonization with carbapenemase-producing enterobacteria (CPE) at Surgical Intensive Care Unit (SICU) admission. METHODS: A 2-year retrospective study was performed in all patients admitted to the SICU that following routine had a rectal swab collected upon admission. RESULTS: Of 254 patients admitted, 41 (16.1%) harbored CPE (five showing two carbapenemase-producing isolates). Most frequent carbapenemase-producing isolates and carbapenemases were K. pneumoniae (39/46, 84.8%) and OXA-48 (31/46; 76.1%), respectively. Carriers significantly had higher rates of chronic renal disease, previous digestive/biliary endoscopy, hospitalization, ICU/SICU admission, intraabdominal surgery, and antibiotic intake, as well as higher median values of clinical scores (SOFA, SAPS II and APACHE II). In the multivariate analysis (R2=0.309, p<0.001), CPE carriage was associated with prior administration of 3rd-4th generation cephalosporins (OR=27.96, 95%CI=6.88, 113.58, p<0.001), ß-lactam/ß-lactamase inhibitor (OR=11.71, 95%CI=4.51, 30.43, p<0.001), abdominal surgery (OR=6.33, 95%CI=2.12, 18.89, p=0.001), and prior digestive/biliary endoscopy (OR=3.88, 95%CI=1.56, 9.67, p=0.004). CONCLUSIONS: A strong association between production of ESBLs and carriage of CPE (mainly OXA-48 producing K. pneumoniae) was found. According to the model, the co-selection of ß-lactamases by previous exposure to broad-spectrum cephalosporins and ß-lactam/ß-lactamase inhibitors (with lower relative risk), abdominal surgery and prior digestive/biliary endoscopy were factors associated with CPE carriage.

Effect of delirium motoric subtypes on administrative documentation of delirium in the surgical intensive care unit.

This study compares the proportions of surgical intensive care unit (ICU) patients with delirium detected using the Confusion Assessment Method for the ICU (CAM-ICU) who received administrative documentation for delirium using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, stratified by delirium motoric subtypes. This retrospective cohort study was conducted at a surgical ICU from 06/2012 to 05/2013. Delirium was assessed twice daily and was defined as having ≥1 positive CAM-ICU rating. Delirious patients were categorized into hyperactive/mixed and hypoactive subtypes using corresponding Richmond Agitation Sedation Scales. Administrative documentation of delirium was defined as having ≥1 of 32 unique ICD-9-CM codes. Proportions were compared using Pearson's Chi-square test. Of included patients, 40 % (423/1055) were diagnosed with delirium, and 17 % (183/1055) had an ICD-9-CM code for delirium. The sensitivity and specificity of ICD-9-CM codes for delirium were 36 and 95 %. ICD-9-CM codes for delirium were available for 42 % (95 % CI 35-48 %; 105/253) of patients with hyperactive/mixed delirium and 27 % (95 % CI 20-34 %; 46/170) of patients with hypoactive delirium (relative risk = 1.5; 95 % CI 1.2-2.0; p = 0.002). ICD-9-CM codes yielded a low sensitivity for identifying patients with CAM-ICU positive delirium and were more likely to identify hyperactive/mixed delirium compared with hypoactive delirium.

Increasing use of less-invasive hemodynamic monitoring in 3 specialty surgical intensive care units: a 5-year experience at a tertiary medical center.

INTRODUCTION: Less-invasive hemodynamic monitoring (eg, esophageal doppler monitoring [EDM] and arterial pressure contour analysis, FloTrac) is increasingly used as an alternative to pulmonary artery catheters (PACs) in critically ill intensive care unit (ICU). HYPOTHESIS: The decrease in use of PACs is not associated with increased mortality. METHODS: Five-year retrospective review of 1894 hemodynamically monitored patients admitted to 3 surgical ICUs in a university-affiliate, tertiary care urban hospital. Data included the number of admissions, diagnosis-related group discharge case mix, length of stay, insertion of monitoring devices (PAC, EDM, and FloTrac probes), administered intravenous vasoactive agents (ß-predominant agonists--dobutamine, epinephrine, and dopamine; vasopressors--norepinephrine and phenylephrine), and mortality. Data from hospital administrative databases were compiled to create patient characteristic and monitoring variables across a 5-year time period, 2005 to 2009 inclusive. Chi-square for independent proportions, 1-way analysis of variance, and Kruskal-Wallis tests were used; tests for trend were conducted. An α level of .05 was considered significant. Statistical Package for the Social Sciences v14 was used for all statistical testing. RESULTS: There was a significant change in the type of hemodynamic monitors inserted in 2 of the 3 surgical ICUs (in the general surgery and neurointensive care but not in the cardiac ICU) from PACs to less-invasive devices (FloTrac or EDM) during the 5-year study period (P < .001). There was no change in mortality rate over the time period (P = .492). There was an overall increase in the proportion of monitored patients who received intravenous vasoactive agents (P < .001) with a progressive shift from ß-agonists to vasopressors (P < .002). Multivariate analyses indicated that age, case mix, and use of vasoactive agents were all independent predictors of inhospital mortality (P = .001) but that type of monitoring was not (P = .638). CONCLUSIONS: In a 5-year period, the decreased insertions of PACs were replaced by increased utilization of less-invasive hemodynamic monitoring devices. This change in practice did not adversely impact mortality.

The distinct role of palliative care in the surgical intensive care unit.

Palliative care is expanding its role into the surgical intensive care units (SICU). Embedding palliative philosophies of care into SICUs has considerable potential to improve the quality of care, especially in complex patient care scenarios. This article will explore palliative care, identifying patients/families who benefit from palliative care services, how palliative care complements SICU care, and opportunities to integrate palliative care into the SICU. Palliative care enhances the SICU team's ability to recognize pain and distress; establish the patient's wishes, beliefs, and values and their impact on decision making; develop flexible communication strategies; conduct family meetings and establish goals of care; provide family support during the dying process; help resolve team conflicts; and establish reasonable goals for life support and resuscitation. Educational opportunities to improve end-of-life management skills are outlined. It is necessary to appreciate how traditional palliative and surgical cultures may influence the integration of palliative care into the SICU. Palliative care can provide a significant, "value added" contribution to the care of seriously ill SICU patients.
