RESUMO
OBJECTIVES: To estimate the use of albumin among adults undergoing thoracic surgery in the United States, compare baseline characteristics, clinical and cost outcomes of recipients versus nonrecipients, and determine albumin's contribution to total hospital costs. DESIGN: Retrospective cohort study. SETTING: Nationwide sample of US hospitals. PARTICIPANTS: Adults undergoing open and minimally invasive thoracic surgery between 2011 and 2017. INTERVENTIONS: Albumin on the day of surgery (identified using itemized hospital billing logs). MEASUREMENTS AND MAIN RESULTS: Albumin was used in 170 of 342 US hospitals, among 13% and 7% of 14,672 and 22,532 patients who, respectively, underwent open and minimally invasive thoracic surgery (median volume 500 mL). Baseline comorbidities and organ-supportive treatments were several-fold more prevalent among recipients (particularly vasopressors, mechanical ventilation, and red cell transfusions). In standardized mortality ratio propensity score weighted analysis, albumin use was not associated with in-hospital mortality (adjusted relative risk 1.17 [0.72, 1.92] and 1.51 [0.97, 2.34], with open and minimally invasive procedures), but was associated with morbidity and higher costs, more so with minimally invasive procedures than with open surgery. Total costs among recipients were higher by $4,744 ($3,591, $5,897) and $5,088 ($4,075, $6,100) for open and minimally invasive procedures, respectively. Albumin accounted for 2.6% of this difference (median $124 [$83-$189] per patient). CONCLUSIONS: Albumin use varies widely across hospitals, and 9% of patients receive it (median 500 mL). Use was not associated with in-hospital mortality and was associated with more morbidity and cost. The cost of albumin accounted for a trivial portion of hospital costs. Clinical trials must examine the effects of albumin on complications and costs after thoracic surgery.
RESUMO
BACKGROUND: Glucagon-like peptide-1 agonist receptors (GLP-1RAs), medications used for glycemic control and weight loss, are increasing worldwide. In the perioperative period, the major concern related to GLP-1RA is gastric emptying delay and risk of aspiration. This meta-analysis and systematic review compared the risks and benefits of using GLP-1 agonist receptors and control in surgical and nonsurgical procedures under anesthesia or sedation. METHODS: We systematically searched MEDLINE, Embase, and Cochrane for randomized controlled trials and observational studies involving patients > 18 years undergoing elective surgeries or procedures. Outcomes of interest were pre-procedural gastrointestinal (GI) symptoms, residual gastric content assessed by endoscopy, pulmonary aspiration during anesthesia/sedation, perioperative glycemic control, postoperative inotropic support, nausea/vomiting (PONV), atrial fibrillation, and 30-day mortality rate. We used a random effects model, with odds ratio and mean difference computed for binary and continuous outcomes, respectively. RESULTS: Fourteen randomized and observational studies with 2143 adult patients undergoing elective surgeries and procedures were included. GLP-1RA resulted in increased pre-procedural GI symptoms (OR 7.66; 95% CI 3.42, 17.17; p < 0.00001; I2 = 0%) and elevated residual gastric content (OR 6.08; 95% CI 2.86, 12.94; p < 0.00001; I2 = 0%). GLP-1RA resulted in lower glycemic levels (MD - 0.73; 95% CI - 1.13, - 0.33; p = 0.0003; I2 = 90%) and lower rate of rescue insulin administration (OR 0.39; 95% CI 0.23, 0.68 p = 0.0009; I2 = 35%). There was no significant difference in rate of perioperative hypoglycemia (OR 0.60; 95% CI 0.29, 1.24; p = 0.17; I2 = 0%), hyperglycemia (OR 0.89; 95% CI 0.59, 1.34; p = 0.58; I2 = 38%), need for postoperative inotropic support (OR 0.57; 95% CI 0.33, 1.01; p = 0.05; I2 = 0%), atrial fibrillation (OR 1.02; 95% CI 0.52, 2.01; p = 0.95; I2 = 16%), rate of PONV (OR 1.35; 95% CI 0.82, 2.21; p = 0.24; I2 = 0%), and 30-day mortality rate (OR 0.54; 95% CI 0.14, 2.05; p = 0.25; I2 = 0%). CONCLUSION: Compared to control, pre-procedural GLP-1RA increased the rate of GI symptoms and the risk of elevated residual gastric content despite adherence to fasting guidelines. GLP-1RA improved glycemic control and decreased the rate of rescue insulin administration. There was no significant difference in the rates of perioperative hypo or hyperglycemia, postoperative inotropic support, PONV, atrial fibrillation, and 30-day mortality.
RESUMO
BACKGROUND: Traumatic brain injury (TBI) triggers autonomic dysfunction and inflammatory response that can result in secondary brain injuries. Dexmedetomidine is an alpha-2 agonist that may modulate autonomic function and inflammation and has been increasingly used as a sedative agent for critically ill TBI patients. We aimed to investigate the association between early dexmedetomidine exposure and blood-based biomarker levels in moderate-to-severe TBI (msTBI). METHODS: We conducted a retrospective cohort study using data from the Transforming Clinical Research and Knowledge in Traumatic Brain Injury Study (TRACK-TBI), which enrolled acute TBI patients prospectively across 18 United States Level 1 trauma centers between 2014-2018. Our study population focused on adults with msTBI defined by Glasgow Coma Scale score 3-12 after resuscitation, who required mechanical ventilation and sedation within the first 48 h of ICU admission. The study's exposure was early dexmedetomidine utilization (within the first 48 h of admission). Primary outcome included brain injury biomarker levels measured from circulating blood on day 3 following injury, including glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase-L1 (UCH-L1), neuron-specific enolase (NSE), S100 calcium-binding protein B (S100B) and the inflammatory biomarker C-reactive protein (CRP). Secondary outcomes assessed biomarker levels on days 5 and 14. Linear mixed-effects regression modelling of the log-transformed response variable was used to analyze the association of early dexmedetomidine exposure with brain injury biomarker levels. RESULTS: Among the 352 TRACK-TBI subjects that met inclusion criteria, 50 (14.2 %) were exposed to early dexmedetomidine, predominantly male (78 %), white (81 %), and non-Hispanic (81 %), with mean age of 39.8 years. Motor vehicle collisions (27 %) and falls (22 %) were common causes of injury. No significant associations were found between early dexmedetomidine exposure with day 3 brain injury biomarker levels (GFAP, ratio = 1.46, 95 % confidence interval [0.90, 2.34], P = 0.12; UCH-L1; ratio = 1.17 [0.89, 1.53], P = 0.26; NSE, ratio = 1.19 [0.92, 1.53], P = 0.19; S100B, ratio = 1.01 [0.95, 1.06], P = 0.82; hs-CRP, ratio = 1.29 [0.91, 1.83], P = 0.15). The hs-CRP level at day 14 in the dexmedetomidine group was higher than that of the non-exposure group (ratio = 1.62 [1.12, 2.35], P = 0.012). CONCLUSIONS: There were no significant associations between early dexmedetomidine exposure and day 3 brain injury biomarkers in msTBI. Our findings suggest that early dexmedetomidine use is not correlated with either decrease or increase in brain injury biomarkers following msTBI. Further research is necessary to confirm these findings.

OBJECTIVES: To describe the utilization of early ketamine use among patients mechanically ventilated for COVID-19, and examine associations with in-hospital mortality and other clinical outcomes. DESIGN: Retrospective cohort study. SETTING: Six hundred ten hospitals contributing data to the Premier Healthcare Database between April 2020 and June 2021. PATIENTS: Adults with COVID-19 and greater than or equal to 2 consecutive days of mechanical ventilation within 5 days of hospitalization. INTERVENTION: The exposures were early ketamine use initiated within 2 days of intubation and continued for greater than 1 day. MEASUREMENTS: Primary was hospital mortality. Secondary outcomes included length of stay (LOS) in the hospital and ICUs, ventilator days, vasopressor days, renal replacement therapy (RRT), and total hospital cost. The propensity score matching analysis was used to adjust for confounders. MAIN RESULTS: Among 42,954 patients, 1,423 (3.3%) were exposed to early ketamine use. After propensity score matching including 1,390 patients in each group, recipients of ketamine infusions were associated with higher hospital mortality (52.5% vs. 45.9%, risk ratio: 1.14, [1.06-1.23]), longer median ICU stay (13 vs. 12 d, mean ratio [MR]: 1.15 [1.08-1.23]), and longer ventilator days (12 vs. 11 d, MR: 1.19 [1.12-1.27]). There were no associations for hospital LOS (17 [10-27] vs. 17 [9-28], MR: 1.05 [0.99-1.12]), vasopressor days (4 vs. 4, MR: 1.04 [0.95-1.14]), and RRT (22.9% vs. 21.7%, RR: 1.05 [0.92-1.21]). Total hospital cost was higher (median $72,481 vs. $65,584, MR: 1.11 [1.05-1.19]). CONCLUSIONS: In a diverse sample of U.S. hospitals, about one in 30 patients mechanically ventilated with COVID-19 received ketamine infusions. Early ketamine may have an association with higher hospital mortality, increased total cost, ICU stay, and ventilator days, but no associations for hospital LOS, vasopressor days, and RRT. However, confounding by the severity of illness might occur due to higher extracorporeal membrane oxygenation and RRT use in the ketamine group. Further randomized trials are needed to better understand the role of ketamine infusions in the management of critically ill patients.

OBJECTIVES: To examine trends in the prevalence of multiorgan dysfunction (MODS), utilization of multi-organ support (MOS), and mortality among patients undergoing cardiac surgery with MODS who received MOS in the United States. DESIGN: Retrospective cohort study. SETTING: 183 hospitals in the Premier Healthcare Database. PARTICIPANTS: Adults ≥18 years old undergoing high-risk elective or non-elective cardiac surgery. INTERVENTIONS: none. MEASUREMENTS AND MAIN RESULTS: The exposure was time (consecutive calendar quarters) January 2008 and June 2018. We analyzed hospital data using day-stamped hospital billing codes and diagnosis and procedure codes to assess MODS prevalence, MOS utilization, and mortality. Among 129,102 elective and 136,190 non-elective high-risk cardiac surgical cases across 183 hospitals, 10,001 (7.7%) and 21,556 (15.8%) of patients developed MODS, respectively. Among patients who experienced MODS, 2,181 (22%) of elective and 5,425 (25%) of non-elective cardiac surgical cases utilized MOS. From 2008-2018, MODS increased in both high-risk elective and non-elective cardiac surgical cases. Similarly, MOS increased in both high-risk elective and non-elective cardiac surgical cases. As a component of MOS, mechanical circulatory support (MCS) increased over time. Over the study period, risk-adjusted mortality, in patients who developed MODS receiving MOS, increased in high-risk non-elective cardiac surgery and decreased in high-risk elective cardiac surgery, despite increasing MODS prevalence and MOS utilization (p<0.001). CONCLUSIONS: Among patients undergoing high-risk cardiac surgery in the United States, MODS prevalence and MOS utilization (including MCS) increased over time. Risk-adjusted mortality trends differed in elective and non-elective cardiac surgery. Further research is necessary to optimize outcomes among patients undergoing high-risk cardiac surgery.

Purpose: To identify risk factors for and outcomes in acute respiratory distress syndrome (ARDS) in patients hospitalized with community-acquired pneumonia (CAP). Methods: This is a retrospective study using the Premier Healthcare Database between 2016 and 2020. Patients diagnosed with pneumonia, requiring mechanical ventilation (MV), antimicrobial therapy, and hospital admission ≥2 days were included. Multivariable regression models were used for outcomes including in-hospital mortality, hospital length of stay (LOS), intensive care unit (ICU) LOS, and days on MV. Results: 1924 (2.7%) of 72â 107 patients with CAP developed ARDS. ARDS was associated with higher mortality (33.7% vs 18.9%; adjusted odds ratio 2.4; 95% confidence interval [CI] 2.16-2.66), longer hospital LOS (13 vs 9 days; adjusted incidence risk ratio (aIRR) 1.24; 95% CI 1.20-1.27), ICU LOS (9 vs 5 days; aIRR 1.51; 95% CI 1.46-1.56), more MV days (8 vs 5; aIRR 1.54; 95% CI 1.48-1.59), and increased hospitalization cost ($46â 459 vs $29â 441; aIRR 1.50; 95% CI 1.45-1.55). Conclusion: In CAP, ARDS was associated with worse in-patient outcomes in terms of mortality, LOS, and hospitalization cost. Future studies are needed to explore outcomes in patients with CAP with ARDS and explore risk factors for development of ARDS after CAP.
RESUMO
BACKGROUND: There is limited evidence that beta-blockers may provide benefit for patients with moderate-severe traumatic brain injury (TBI) during the acute injury period. Larger studies on utilization patterns and impact on outcomes in clinical practice are lacking. OBJECTIVE: The present study uses a large, national hospital claims-based dataset to examine early beta-blocker utilization patterns and its association with clinical outcomes among critically ill patients with moderate-severe TBI. METHODS: We conducted a retrospective cohort study of the administrative claims Premier Healthcare Database of adults (≥17 years) with moderate-severe TBI admitted to the intensive care unit (ICU) from 2016 to 2020. The exposure was receipt of a beta-blocker during day 1 or 2 of ICU stay (BB+). The primary outcome was hospital mortality, and secondary outcomes were: hospital length of stay (LOS), ICU LOS, discharge to home, and vasopressor utilization. In a sensitivity analysis, we explored the association of beta-blocker class (cardioselective and noncardioselective) with hospital mortality. We used propensity weighting methods to address possible confounding by treatment indication. RESULTS: A total of 109â 665 participants met inclusion criteria and 39% (n = 42â 489) were exposed to beta-blockers during the first 2 days of hospitalization. Of those, 42% received cardioselective only, 43% received noncardioselective only, and 14% received both. After adjustment, there was no association with hospital mortality in the BB+ group compared to the BB- group (adjusted odds ratio [OR] = 0.99, 95% confidence interval [CI] = 0.94, 1.04). The BB+ group had longer hospital stays, lower chance of discharged home, and lower risk of vasopressor utilization, although these difference were clinically small. Beta-blocker class was not associated with hospital mortality. CONCLUSION: In this retrospective cohort study, we found variation in use of beta-blockers and early exposure was not associated with hospital mortality. Further research is necessary to understand the optimal type, dose, and timing of beta-blockers for this population.

BACKGROUND: Traumatic brain injury (TBI) is an expensive and common public health problem. Management of TBI oftentimes includes sedation to facilitate mechanical ventilation (MV) for airway protection. Dexmedetomidine has emerged as a potential candidate for improved patient outcomes when used for early sedation after TBI due to its potential modulation of autonomic dysfunction. We examined early sedation patterns, as well as the association of dexmedetomidine exposure with clinical and functional outcomes among mechanically ventilated patients with moderate-severe TBI (msTBI) in the United States. METHODS: We conducted a retrospective cohort study using data from the Premier dataset and identified a cohort of critically ill adult patients with msTBI who required MV from January 2016 to June 2020. msTBI was defined by head-neck abbreviated injury scale (AIS) values of 3 (serious), 4 (severe), and 5 (critical). We described early continuous sedative utilization patterns. Using propensity-matched models, we examined the association of early dexmedetomidine exposure (within 2 days of intensive care unit [ICU] admission) with the primary outcome of hospital mortality and the following secondary outcomes: hospital length of stay (LOS), days on MV, vasopressor use after the first 2 days of admission, hemodialysis (HD) after the first 2 days of admission, hospital costs, and discharge disposition. All medications, treatments, and procedures were identified using date-stamped hospital charge codes. RESULTS: The study population included 19,751 subjects who required MV within 2 days of ICU admission. The patients were majority male and white. From 2016 to 2020, the annual percent utilization of dexmedetomidine increased from 4.05% to 8.60%. After propensity score matching, early dexmedetomidine exposure was associated with reduced odds of hospital mortality (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.47-0.74; P < .0001), increased risk for liberation from MV (hazard ratio [HR], 1.20; 95% CI, 1.09-1.33; P = .0003), and reduced LOS (HR, 1.11; 95% CI, 1.01-1.22; P = .033). Exposure to early dexmedetomidine was not associated with odds of HD (OR, 1.14; 95% CI, 0.73-1.78; P = .56), vasopressor utilization (OR, 1.10; 95% CI, 0.78-1.55; P = .60), or increased hospital costs (relative cost ratio, 1.98; 95% CI, 0.93-1.03; P = .66). CONCLUSIONS: Dexmedetomidine is being utilized increasingly as a sedative for mechanically ventilated patients with msTBI. Early dexmedetomidine exposure may lead to improved patient outcomes in this population.

Dexmedetomidine is a promising alternative sedative agent for moderate-severe Traumatic brain injury (TBI) patients. Although the data are limited, the posited benefits of dexmedetomidine in this population are a reduction in secondary brain injury compared with current standard sedative regimens. In this scoping review, we critically appraised the literature to examine the effects of dexmedetomidine in patients with moderate-severe TBI to examine the safety, efficacy, and cerebral and systemic physiological outcomes within this population. We sought to identify gaps in the literature and generate directions for future research. Two researchers and a librarian queried PubMed, Embase, Scopus, and APA PsycINFO databases. Of 920 studies imported for screening, 11 were identified for inclusion in the review. The primary outcomes in the included studied were cerebral physiology, systemic hemodynamics, sedation levels and delirium, and the presence of paroxysmal sympathetic hyperactivity. Dexmedetomidine dosing ranged from 0.2 to 1 ug/kg/h, with 3 studies using initial boluses of 0.8 to 1.0 ug/kg over 10 minutes. Dexmedetomidine used independently or as an adjunct seems to exhibit a similar hemodynamic safety profile compared with standard sedation regimens, albeit with transient episodes of bradycardia and hypotension, decrease episodes of agitation and may serve to alleviate symptoms of sympathetic hyperactivity. This scoping review suggests that dexmedetomidine is a safe and efficacious sedation strategy in patients with TBI. Given its rapid onset of action and anxiolytic properties, dexmedetomidine may serve as a feasible sedative for TBI patients.

Importance: Patients with head and neck cancer (HNC) have an increased risk of malnutrition, partly due to disease location and treatment sequelae. Although malnutrition is associated with adverse outcomes, there is little data on the extent of outcomes and the sociodemographic factors associated with malnutrition in patients with HNC. Objectives: To investigate the association of race, ethnicity, and payer type with perioperative malnutrition in patients undergoing HNC surgery and how malnutrition affects clinical outcomes. Design, Setting, and Participants: This retrospective cohort study used data from the Premier Healthcare Database to assess adult patients who had undergone HNC surgery from January 2008 to June 2020 at 482 hospitals across the US. Diagnosis and procedure codes were used to identify a subset of patients with perioperative malnutrition. Patient characteristics, payer types, and hospital outcomes were then compared to find associations among race, ethnicity, payer type, malnutrition, and clinical outcomes using multivariable logistic regression models. Analyses were performed from August 2022 to January 2023. Exposures: Race, ethnicity, and payer type for primary outcome, and perioperative malnutrition status, race, ethnicity, and payer type for secondary outcomes. Main Outcomes and Measures: Perioperative malnutrition status. Secondary outcomes were discharge to home after surgery, hospital length of stay (LOS), total cost, and postoperative pulmonary complications (PPCs). Results: The study population comprised 13â¯895 adult patients who had undergone HNC surgery during the study period; they had a mean (SD) age of 63.4 (12.1) years; 9425 male (67.8%) patients; 968 Black (7.0%), 10 698 White (77.0%), and 2229 (16.0%) individuals of other races; and 887 Hispanic (6.4%) and 13 008 non-Hispanic (93.6%) individuals. Among the total sample, there were 3136 patients (22.6%) diagnosed with perioperative malnutrition. Compared with White patients and patients with private health insurance, the odds of malnutrition were higher for non-Hispanic Black patients (adjusted odds ratio [aOR], 1.31; 95% CI, 1.11-1.56), Medicaid-insured patients (aOR, 1.68; 95% CI, 1.46-1.95), and Medicare-insured patients (aOR, 1.24; 95% CI, 1.10-1.73). Black patients and patients insured by Medicaid had increased LOS, costs, and PPCs, and lower rates of discharge to home. Malnutrition was independently associated with increased LOS (ß, 5.20 additional days; 95% CI, 4.83-5.64), higher costs (ß, $15â¯722 more cost; 95% CI, $14â¯301-$17â¯143), increased odds of PPCs (aOR, 2.04; 95% CI, 1.83-2.23), and lower odds of discharge to home (aOR, 0.34; 95% CI, 0.31-0.38). No independent association between malnutrition and mortality was observed. Conclusions and Relevance: This retrospective cohort study found that 1 in 5 patients undergoing HNC surgery were malnourished. Malnourishment disproportionately affected Black patients and patients with Medicaid, and contributed to longer hospital stays, higher costs, and more postoperative complications.

OBJECTIVE: To examine early sedation patterns, as well as the association of dexmedetomidine exposure, with clinical and functional outcomes among mechanically ventilated patients with moderate-severe traumatic brain injury (msTBI). DESIGN: Retrospective cohort study with prospectively collected data. SETTING: Eighteen Level-1 Trauma Centers, United States. PATIENTS: Adult (age > 17) patients with msTBI (as defined by Glasgow Coma Scale < 13) who required mechanical ventilation from the Transforming Clinical Research and Knowledge in TBI (TRACK-TBI) study. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Using propensity-weighted models, we examined the association of early dexmedetomidine exposure (within the first 5 d of ICU admission) with the primary outcome of 6-month Glasgow Outcomes Scale Extended (GOS-E) and the following secondary outcomes: length of hospital stay, hospital mortality, 6-month Disability Rating Scale (DRS), and 6-month mortality. The study population included 352 subjects who required mechanical ventilation within 24 hours of admission. The initial sedative medication was propofol for 240 patients (68%), midazolam for 59 patients (17%), ketamine for 6 patients (2%), dexmedetomidine for 3 patients (1%), and 43 patients (12%) never received continuous sedation. Early dexmedetomidine was administered in 77 of the patients (22%), usually as a second-line agent. Compared with unexposed patients, early dexmedetomidine exposure was not associated with better 6-month GOS-E (weighted odds ratio [OR] = 1.48; 95% CI, 0.98-2.25). Early dexmedetomidine exposure was associated with lower DRS (weighted OR = -3.04; 95% CI, -5.88 to -0.21). In patients requiring ICP monitoring within the first 24 hours of admission, early dexmedetomidine exposure was associated with higher 6-month GOS-E score (OR 2.17; 95% CI, 1.24-3.80), lower DRS score (adjusted mean difference, -5.81; 95% CI, -9.38 to 2.25), and reduced length of hospital stay (hazard ratio = 1.50; 95% CI, 1.02-2.20). CONCLUSION: Variation exists in early sedation choice among mechanically ventilated patients with msTBI. Early dexmedetomidine exposure was not associated with improved 6-month functional outcomes in the entire population, although may have clinical benefit in patients with indications for ICP monitoring.

BACKGROUND: Patients with pulmonary hypertension have a high risk of maternal morbidity and mortality. It is unknown if a trial of labor carries a lower risk of morbidity in these patients compared to a planned cesarean delivery. The objective of this study was to examine the association of delivery mode with severe maternal morbidity events during delivery hospitalization among patients with pulmonary hypertension. METHODS: This retrospective cohort study used the Premier inpatient administrative database. Patients delivering ≥25 weeks gestation from January 1, 2016, to September 30, 2020, and with pulmonary hypertension were included. The primary analysis compared intended vaginal delivery (ie, trial of labor) to intended cesarean delivery (intention to treat analysis). A sensitivity analysis was conducted comparing vaginal delivery to cesarean delivery (as treated analysis). The primary outcome was nontransfusion severe maternal morbidity during the delivery hospitalization. Secondary outcomes included blood transfusion (4 or more units) and readmission to the delivery hospital within 90 days from discharge from delivery hospitalization. RESULTS: The cohort consisted of 727 deliveries. In the primary analysis, there was no difference in nontransfusion morbidity between intended vaginal delivery and intended cesarean delivery groups (adjusted odds ratio [aOR], 0.75; 95% confidence interval [CI], 0.49-1.15). In secondary analyses, intended cesarean delivery was not associated with blood transfusion (aOR, 0.71; 95% CI, 0.34-1.50) or readmission within 90 days (aOR, 0.60; 95% CI, 0.32-1.14). In the sensitivity analysis, cesarean delivery was associated with a 3-fold higher risk of nontransfusion morbidity compared to vaginal delivery (aOR, 2.64; 95% CI, 1.54-3.93), a 3-fold higher risk of blood transfusion (aOR, 3.06; 95% CI, 1.17-7.99), and a 2-fold higher risk of readmission within 90 days (aOR, 2.20; 95% CI, 1.09-4.46) compared to vaginal delivery. CONCLUSIONS: Among pregnant patients with pulmonary hypertension, a trial of labor was not associated with a higher risk of morbidity compared to an intended cesarean delivery.

BACKGROUND AND AIMS: Data suggest that guidelines for enteral nutrition (EN) initiation are not closely followed in clinical practice. In addition, critically ill mechanically ventilated (MV) patients have varying metabolic needs, which often increase and persist over time, requiring personalized nutrition intervention. While both over- and under-nutrition can impact patient outcomes, recent data suggest that targeted early EN delivery may reduce mortality and improve clinical outcomes. This study examined if early EN improves clinical outcomes and decreases costs in critically ill patients on MV. METHODS: Data from a nationwide administrative-financial database between 2018 and 2020 was utilized to identify eligible adult critical care patients. Patients who received EN within 3 days after intubation (early EN) were compared to patients who started EN after 3 days of intubation (late EN). Outcomes of interest included hospital mortality, discharge disposition, hospital and intensive care unit (ICU) length of stay (LOS), MV days, and total cost. After inverse-probability-of-treatment weighting, outcomes were modeled using a nominal logistic regression model for hospital mortality and discharge disposition, a linear regression model for cost, and Cox proportional-hazards model for MV days, hospital and ICU LOS. RESULTS: A total of 27,887 adult patients with early MV were identified, of which 16,772 (60.1%) received early EN. Regression analyses showed that the early EN group had lower hospital mortality (OR = 0.88, 95% CI, 0.82 to 0.94), were more likely to be discharged home (OR = 1.47, 95% CI 1.38 to 1.56), had fewer MV days (HR = 1.23, 95% CI, 1.11 to 1.37), shorter hospital LOS (HR = 1.43, 95% CI, 1.33 to 1.54) and ICU LOS (HR = 1.36, 95% CI, 1.27 to 1.46), and lower cost (-$21,226; 95% CI, -$23,605 to -$18,848) compared to the late EN group. CONCLUSIONS: Early EN within 3 days of MV initiation in real-world practice demonstrated improved clinical and economic outcomes. These data suggest that early EN is associated with decreased hospital mortality, increased discharge to home, and decreased hospital and ICU LOS, time on MV, and cost compared to delayed initiation of EN; highlighting the importance of early EN to optimize utcomes ando support the recovery of critically ill patients on MV.

OBJECTIVES: We aimed to 1) describe patterns of beta-blocker utilization among critically ill patients following moderate-severe traumatic brain injury (TBI) and 2) examine the association of early beta-blocker exposure with functional and clinical outcomes following injury. DESIGN: Retrospective cohort study. SETTING: ICUs at 18 level I, U.S. trauma centers in the Transforming Clinical Research and Knowledge in TBI (TRACK-TBI) study. PATIENTS: Greater than or equal to 17 years enrolled in the TRACK-TBI study with moderate-severe TBI (Glasgow Coma Scale of <13) were admitted to the ICU after a blunt TBI. INTERVENTIONS: None. MEASUREMENTS: Primary exposure was a beta blocker during the first 7 days in the ICU, with a primary outcome of 6-month Glasgow Outcome Scale-Extended (GOSE). Secondary outcomes included: length of hospital stay, in-hospital mortality, 6-month and 12-month mortality, 12-month GOSE score, and 6-month and 12-month measures of disability, well-being, quality of life, and life satisfaction. MAIN RESULTS: Of the 450 eligible participants, 57 (13%) received early beta blockers (BB+ group). The BB+ group was on average older, more likely to be on a preinjury beta blocker, and more likely to have a history of hypertension. In the BB+ group, 34 participants (60%) received metoprolol only, 19 participants (33%) received propranolol only, 3 participants (5%) received both, and 1 participant (2%) received atenolol only. In multivariable regression, there was no difference in the odds of a higher GOSE score at 6 months between the BB+ group and BB- group (odds ratio = 0.86; 95% CI, 0.48-1.53). There was no association between BB exposure and secondary outcomes. CONCLUSIONS: About one-sixth of subjects in our study received early beta blockers, and within this group, dose, and timing of beta-blocker administration varied substantially. No significant differences in GOSE score at 6 months were demonstrated, although our ability to draw conclusions is limited by overall low total doses administered compared with prior studies.
RESUMO
The critical care medicine (CCM) fellowship is an opportunity for advanced anesthesiology trainees to refine their quality improvement (QI) skills. However, the short training period and inconsistent curricula make this challenging. The QI fellow (QIF) is described as an education program to provide consistent QI training during the CCM fellowship. The QIF is a mentored position to help manage data review, QI conferences, and improvement efforts within the CCM Division. The curriculum is focused on a QI education framework and mentored experiential learning. The QIF program is an opportunity for education and mentorship in the role of a CCM operational leader.

Importance: Critically ill pediatric patients often require parenteral nutrition (PN) in the intensive care unit (ICU). Literature suggests mixed lipid emulsions (LE) with soybean oil reduction strategies may improve outcomes. Objective: To examine the association of a hospital-wide switch to a mixed-lipid formula (4-OLE) with pediatric outcomes. Design, Setting, and Participants: Retrospective cohort study at a large US academic referral center. Pediatric patients aged 1 month to 17 years requiring parenteral nutrition from May 2016 to September 2019 were included. Data were analyzed from October 2020 to February 2023. Exposure: In 2017, Duke University Health System fully converted to a soybean oil/MCT/olive/fish oil lipid (4-OLE) from pure soybean oil-based LE in pediatric patients. Pediatric patients before the change (Intralipid [IL] group) were compared with patients after (4-OLE group). Main Outcomes and Measures: Clinical outcomes were compared between treatment periods via multivariable regression models. The primary outcome was hospital length of stay (LOS). Fourteen secondary outcomes included hospital mortality of any cause, 30-day or 90-day readmission, pneumonia, urinary tract infections (UTIs), total caloric delivery, and liver function tests (aspartate aminotransferase, alanine transaminase, alkaline phosphatase, and total bilirubin). Results: A total of 684 children dependent on PN were identified (342 were critically ill), with 30% (206 children) in the preswitch (IL) period and 70% (478 children) in the postswitch (4-OLE) period; 123 were male (59.7%). In comparing IL vs 4-OLE, there was a significant difference in median (IQR) age (4.0 [1.2-13.0] vs 3.0 [0.8-9.0] years, respectively; P = .04), without difference in body mass index or baseline comorbidities except for significant differences in cancer diagnosis (26 patients in the IL group [12.6%] vs 29 patients in the 4-OLE group [6.1%]; P = .004) and chronic obstructive pulmonary disease (24 patients in the IL group [11.7%] vs 30 patients in the 4-OLE group [6.3%]; P = .02). In the all children cohort, 4-OLE was associated with shorter hospital LOS (IRR, 0.81; 95% CI, 0.05-0.78), and reduced UTI risk (OR, 0.33; 95% CI, 0.18-0.64). In the ICU cohort, 4-OLE was associated with shorter hospital LOS (IRR, 0.81; 95% CI, 0.78-0.83), and reduced UTI risk (OR, 0.23; 95% CI, 0.11-0.51). Other secondary outcomes were not significant. Conclusions and Relevance: In this observational study of clinical outcomes among children dependent on PN, a switch to 4-OLE in a large academic hospital was associated with a significant decrease in hospital LOS in ICU and non-ICU patients. These findings suggest switching to a soy-LE sparing strategy using 4-OLE is feasible, safe, and associated with improved clinical outcomes in pediatric PN patients.

OBJECTIVES: To describe frequency of positive blood cultures, patterns of pathogens' characteristics and their resistance profile in patients with blood cultures drawn due to a presumed diagnosis of community-onset sepsis, and to examine the association between blood culture-positive pathogens and hospital mortality. DESIGN: Retrospective cohort study. SETTING: Two hundred one U.S. hospitals from 2016 to 2020 using the Premier Healthcare Database. SUBJECTS: Adult patients presenting with community-onset sepsis who had blood cultures collected within 2 days of hospital admission. We defined sepsis using the U.S. Centers for Disease Control Adult Sepsis Event Surveillance criteria. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We identified 147,061 patients with community-onset sepsis. The number of blood culture-positive sepsis episodes was 21,167 (14%) and the number of nonblood culture-positive sepsis episodes was 20,326 (14%). Among patients with blood culture-positive sepsis, Gram-negative rods were isolated in 55% of patients, Gram-positive cocci were isolated in 47%. Of those, methicillin-resistant Staphylococcus aureus (MRSA) was 11%, ceftriaxone-resistant Enterobacterales /extended-spectrum ß-lactamase was 7%, and carbapenem-resistant Enterobacterales was 1.3%. The crude in-hospital mortality was 17% for culture-negative sepsis, 13% for nonblood culture-positive sepsis, and 17% for blood culture-positive sepsis. In multilevel logistic regression models, compared with culture-negative sepsis, blood culture-positive sepsis (adjusted odds ratio [aOR], 0.89; 95% CI, 0.85-0.94) and nonblood culture-positive sepsis (aOR, 0.82; 95% CI, 0.78-0.87) were associated with lower odds of in-hospital mortality. Acinetobacter species, Pseudomonas aeruginosa , methicillin-sensitive Staphylococcus aureus , and MRSA were associated with higher in-hospital mortality, whereas Escherichia coli , Klebsiella species, Proteus species, and Streptococcus species were associated with lower in-hospital mortality. CONCLUSIONS: In patients hospitalized with community-onset sepsis, the prevalence of blood culture-positive sepsis was 14%. Among positive blood culture sepsis resistant organisms were infrequent. Compared with culture-negative sepsis, blood culture-positive sepsis and nonblood culture-positive sepsis were associated with lower in-hospital mortality.
