Project description:MAIN OBJECTIVES:Echocardiographic parameters have been used to predict outcomes for specific intensive care unit (ICU) populations. We sought to define echocardiographic parameters for ICU patients receiving continuous renal replacement therapy (CRRT). DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS:This is a historical cohort study of consecutive ICU patients at Mayo Clinic (Rochester, Minnesota) who received CRRT from December 9, 2006, through November 13, 2015. Only patients with an echocardiographic examination within 7 days of CRRT initiation were considered. RESULTS:The study included 1,276 patients. Decreased left ventricular ejection fraction (LVEF; ?45%) was noted in 361/1,120 (32%) and increased right ventricular systolic pressure (RVSP; ?40 mm Hg) was noted in 529/798 (66%). Right ventricular systolic dysfunction was observed in 320/820 (39%). The most common valvular abnormality was tricuspid regurgitation (244/1,276 [19%]). Stratification of these parameters by ICU type (medical, surgical, cardiothoracic, cardiac) showed that most echocardiographic abnormalities were significantly more prevalent among cardiac ICU patients: LVEF ?45% (67/105 [64%]), RVSP ?40 mm Hg (63/79 [80%]) and tricuspid regurgitation (50/130 [38%]). We compared patients with acute kidney injury (AKI) vs end-stage renal disease and showed that decreased LVEF (284/921 [31%] vs 78/201 [39%]), was significantly less prevalent among patients with AKI, but increased RVSP was more prevalent (445/651 [68%] vs 84/147 [57%]) with AKI. CONCLUSIONS:ICU patients who required CRRT had increased prevalence of pulmonary hypertension and right and left ventricular systolic dysfunction. Prediction of adverse outcomes with echocardiographic parameters in this patient population can lead to identification of modifiable risk factors.

Project description:Introduction: Severe acute kidney injury is a common finding in the Pediatric Intensive Care Unit (PICU), however, Continuous Renal Replacement Therapy (CRRT) is rarely applied in this setting. This study aims to describe our experience in the rate of application of CRRT, patients' clinical characteristics at admission and CRRT initiation, CRRT prescription, predictors of circuit clotting, short- and long-term outcomes. Methods: A 6-year single center retrospective study in a tertiary PICU. Results: Twenty-eight critically ill patients aged 0 to 18 years received CRRT between January 2012 and December 2017 (1.4% of all patients admitted to PICU). Complete clinical and CRRT technical information were available for 23/28 patients for a total of 101 CRRT sessions. CRRT was started, on average, 40 h (20-160) after PICU admission, mostly because of fluid overload. Continuous veno-venous hemodiafiltration and systemic heparinization were applied in 83.2 and 71.3% of sessions, respectively. Fifty-nine sessions (58.4%) were complicated by circuit clotting. At multivariate Cox-regression analysis, vascular access caliber larger than 8 Fr [HR 0.37 (0.19-0.72), p = 0.004] and regional citrate anticoagulation strategy [HR 0.14 (0.03-0.60), p = 0.008] were independent protective factors for clotting. PICU mortality rate was 42.8%, and six survivors developed chronic kidney disease (CKD), within an average follow up of 3.5 years. Conclusions: CRRT is uncommonly applied in our PICU, mostly within 2 days after admission and because of fluid overload. Larger vascular access and citrate anticoagulation are independent protective factors for circuit clotting. Patients' PICU mortality rate is high and survival often complicated by CKD development.

Project description:Introduction:Consistent medical knowledge acquisition while caring for the critically ill can be challenging for learners and educators in the pediatric intensive care unit (PICU), a unit often distinguished by fluctuating acuity and severity. We implemented a standardized didactic curriculum for PICU residents to facilitate their acquisition and retention of knowledge in core PICU topics. Methods:We developed a comprehensive standardized curriculum for PGY 2-PGY 4 PICU pediatric and internal medicine-pediatric residents. Thirteen core topics were administered as 30-minute didactic sessions during the rotation, using either PowerPoint slides or a dry-erase board. Residents were tested to assess knowledge acquisition and retention. Results:Seventy-eight residents participated, 86% of whom completed posttests. Seventeen percent completed follow-up tests. Of the learners who participated, 60 (77%) completed pretests and posttests, indicating their confidence level each time. The pretest mean was 55% (SD = 14.4%), and the posttest mean was 64% (SD = 15.6%). This 9% increase was statistically significant (p = .001; CI, 3.9% to 14.8%). The follow-up test at 3 months, completed by 15% of this subgroup, demonstrated a mean score of 62% (SD = 14.5%). When matched with posttest scores (mean score of 64%, SD = 13.3%), there was no significant difference (p = .7398; CI, -11.7% to 16.2%), suggesting retention of previously acquired knowledge. Discussion:Our standardized didactic curriculum effectively facilitated the acquisition and retention of the medical knowledge of core PICU topics among PICU residents, in addition to their usual experiential learning.

Project description:BackgroundOutcome for critically ill patients with COVID-19 treated with continuous renal replacement therapy (CRRT) is largely unknown. We describe mortality and renal outcome in this group.MethodsThis observational study was conducted at a university hospital in Sweden. We studied critically ill adult COVID-19 patients with Acute Kidney injury (AKI) who received CRRT.ResultsIn 451 patients, AKI incidence was 43.7%. 18.2% received CRRT. Median age of CRRT patients was 60 years (IQR 54-65), 90% were male, median BMI was 29 (IQR 25-32), 23.2% had Diabetes, 37.8% hypertension and 6.1% chronic kidney disease prior to admission. 100% required mechanical ventilation. 8.5% received Extra Corporeal Membrane Oxygenation. Median length of stay was 23 days (IQR 15-26). ICU mortality was 39% and 90-day mortality was 45.1%. Age, baseline creatinine values and body weight change were associated with 60 days mortality. Of the survivors, no patients required dialysis at hospital discharge, 73.8% recovered renal function and a median 10.5% of body weight was lost during admission.ConclusionsCritically ill COVID-19 patients with AKI who received CRRT had a 90-day mortality of 45.1%. At follow-up, three quarters of survivors had recovered renal function. This information is important in the clinical management of COVID-19.

Project description:Thyroid hormones are key factors necessary for normal growth and development in children. They have tight control of metabolic rate and, as a result, frequently become altered in their synthesis and/or release during times of stress or critical illness. Disturbances in thyroid hormone homeostasis have been well described in several pathologic states, including sepsis/septic shock, renal failure, trauma, severe malnutrition, and following cardiopulmonary bypass. Specifically, a decrease in serum triiodothyronine (T3) and a concomitant increase in reverse triiodothyronine (rT3) levels are the most common changes observed. It is further noteworthy that serum thyroxine (T4), rT3, and T3 levels change in relation to severity of nonthyroidal illness. Many past investigators have speculated that these alterations are a teleological adaptation to severe illness and the increased metabolic demands that critical illness bears. However, this paradigm has been challenged through multiple avenues and has lost support over the past few years. Instead the "inflammatory hypothesis" has emerged implicating a cytokine surge as the mediator of thyroid hormone disruption. Overall, the demonstrated association between low thyroid hormone levels and poor clinical outcomes, the beneficial effects of thyroid hormone supplementation in multiple critically ill subpopulations, and the well-established safety profile of T3 therapy make thyroid hormone supplementation in the pediatric ICU worth consideration.

Project description:We determined whether we could identify clusters of children with critical asthma by plasma cytokine concentration. Differences in gene expression between the two clusters were analyzed using a targeted Nanostring immunology array. We performed a single-center, prospective, observational cohort study of 64 children ages 6 – 17 years admitted to a pediatric intensive care unit for an asthma attack between July 2019 to February 2021.

Project description:Introduction:Point-of-care ultrasound (POCUS) is ultrasound performed by the provider at the patient's bedside to answer a specific clinical question. No guidelines exist for teaching POCUS to pediatric residents, and there are currently no pediatric-specific POCUS resources on MedEdPORTAL. To fill this gap, we designed an educational resource to introduce pediatric residents to POCUS during their pediatric intensive care unit (PICU) rotation. Methods:Our POCUS curriculum included content on ultrasound basics, lung ultrasound, and focused cardiac ultrasound. Residents completed a precourse knowledge test at the start of the PICU rotation. Self-study modules were provided to the residents for independent review. During small group, residents performed ultrasound scanning on subjects with normal anatomy. Residents also participated in weekly POCUS rounds to perform supervised ultrasound scanning on PICU patients with known abnormal ultrasound findings. After completion of the PICU rotation, residents competed a postcourse knowledge test and survey. Knowledge test scores were compared to a historical cohort of residents who had completed the PICU rotation but not the POCUS curriculum. Results:Six residents completed the curriculum, and all completed the postcourse knowledge test with significant improvement in test scores compared to a historical cohort. Residents reported increased knowledge of POCUS indications and comfort performing POCUS. All residents rated the small-group sessions and POCUS rounds highly. Discussion:Pediatric residents have little POCUS training and perform poorly on POCUS knowledge testing. A basic POCUS curriculum can be instituted during the PICU rotation and improve resident knowledge and comfort with POCUS.

Project description:Purpose of review:With increasing survival of children requiring admission to pediatric intensive care units (PICU), neurodevelopmental outcomes of these patients are an area of increased attention. Our goal was to systematically review recently published literature on neurologic outcomes of PICU patients. Recent Findings:Decline in neurofunctional status occurs in 3%-20% of children requiring PICU care. This proportion varies based on primary diagnosis and severity of illness, with children admitted for primary neurologic diagnosis, children who suffer cardiac arrest or who require invasive interventions during the PICU admission, having worse outcomes. Recent research focuses on early identification and treatment of modifiable risk factors for unfavorable outcomes, and on long-term follow-up that moves beyond global cognitive outcomes and is increasingly including tests assessing multidimensional aspects of neurodevelopment. Summary:The pediatric critical care research community has shifted focus from survival to survival with favorable neurologic outcomes of children admitted to the PICU.

Project description:Critically ill patients with requirement of continuous renal replacement therapy (CRRT) represent a growing intensive care unit (ICU) population. Optimal CRRT delivery demands continuous communication between stakeholders, iterative adjustment of therapy, and quality assurance systems. This Quality Improvement (QI) study reports the development, implementation and outcomes of a quality assurance system to support the provision of CRRT in the ICU. This study was carried out at the University of Kentucky Medical Center between September 2016 and June 2019. We implemented a quality assurance system using a step-wise approach based on the (a) assembly of a multidisciplinary team, (b) standardization of the CRRT protocol, (c) creation of electronic CRRT flowsheets, (d) selection, monitoring and reporting of quality metrics of CRRT deliverables, and (e) enhancement of education. We examined 34-month data comprising 1185 adult patients on CRRT (~ 7420 patient-days of CRRT) and tracked selected QI outcomes/metrics of CRRT delivery. As a result of the QI interventions, we increased the number of multidisciplinary experts in the CRRT team and ensured a continuum of education to health care professionals. We maximized to 100% the use of continuous veno-venous hemodiafiltration and doubled the percentage of patients using regional citrate anticoagulation. The delivered CRRT effluent dose (~ 30 ml/kg/h) and the delivered/prescribed effluent dose ratio (~ 0.89) remained stable within the study period. The average filter life increased from 26 to 31 h (p = 0.020), reducing the mean utilization of filters per patient from 3.56 to 2.67 (p = 0.054) despite similar CRRT duration and mortality rates. The number of CRRT access alarms per treatment day was reduced by 43%. The improvement in filter utilization translated into ~ 20,000 USD gross savings in filter cost per 100-patient receiving CRRT. We satisfactorily developed and implemented a quality assurance system for the provision of CRRT in the ICU that enabled sustainable tracking of CRRT deliverables and reduced filter resource utilization at our institution.
