Biology of sepsis: its relevance to pediatric nephrology.

Because of its multi-organ involvement, the syndrome of sepsis provides clinical challenges to a wide variety of health care providers. While multi-organ dysfunction triggered by sepsis requires general supportive critical care provided by intensivists, the impact of sepsis on renal function and the ability of renal replacement therapies to modulate its biologic consequences provide a significant opportunity for pediatric nephrologists and related care providers to impact outcomes. In this review, we aim to highlight newer areas of understanding of the pathobiology of sepsis with special emphasis on those aspects of particular interest to pediatric nephrology. As such, we aim to: (1) review the definition of sepsis and discuss advances in our mechanistic understanding of sepsis; (2) review current hypotheses regarding sepsis-induced acute kidney injury (AKI) and describe its epidemiology based on evolving definitions of AKI; (3) review the impact of renal failure on the immune system, highlighting the sepsis risk in this cohort and strategies that might minimize this risk; (4) review how renal replacement therapeutic strategies may impact sepsis-induced AKI outcomes. By focusing the review on these specific areas, we have omitted other important areas of the biology of sepsis and additional interactions with renal function from this discussion; however, we have aimed to provide a comprehensive list of references that provide contemporary reviews of these additional areas.

Development of an Approach to Assessing Pediatric Fellows' Transport Medical Control Skills.

BACKGROUND AND OBJECTIVE: Pediatric interfacility transport teams facilitate access to subspecialty care, and physicians often guide management remotely as transport medical control (TMC). Pediatric subspecialty fellows frequently perform TMC duties, but tools assessing competency are lacking. Our objective was to develop content validity for the items required to assess pediatric subspecialty fellows' TMC skills. METHODS: We conducted a modified Delphi process among transport and fellow education experts in pediatric critical care medicine, pediatric emergency medicine, neonatal-perinatal medicine, and pediatric hospital medicine. The study team generated an initial list of items on the basis of a literature review and personal experience. A modified Delphi panel of transport experts was recruited to participate in 3 rounds of anonymous, online voting on the importance of the items using a 3-point Likert scale (marginal, important, essential). We defined consensus for inclusion as ≥80% agreement that an item was important/essential and consensus for exclusion as ≥80% agreement that an item was marginal. RESULTS: The study team of 20 faculty drafted an initial list of items. Ten additional experts in each subspecialty served on the modified Delphi panel. Thirty-six items met the criteria for inclusion, with widespread agreement across subspecialties. Only 1 item, "discussed bed availability," met the criteria for inclusion among some subspecialties but not others. The study team consolidated the final list into 26 items for ease of use. CONCLUSIONS: Through a consensus-based process among transport experts, we generated content validity for the items required to assess pediatric subspecialty fellows' TMC skills.

Intracranial pressure/cerebral perfusion pressure-targeted management of life-threatening intracranial hypertension complicating diabetic ketoacidosis-associated cerebral edema: a case report.

Symptomatic cerebral edema from diabetic ketoacidosis occurs infrequently but carries a high rate of mortality and morbidity owing to complications from intracranial hypertension. Treatment options are limited but include hyperosmolar therapy with mannitol or hypertonic saline, tracheal intubation for airway protection, and hyperventilation via mechanical ventilation. We describe here the successful use of an intracranial pressure/cerebral perfusion pressure-targeted management strategy through ventriculostomy catheter placement with intracranial pressure monitoring and cerebrospinal fluid drainage, hyperosmolar therapy with hypertonic saline, and controlled hyperventilation to treat life-threatening complications of cerebral edema in a pediatric patient with severe diabetic ketoacidosis.

Acute Management of Prolonged, Recalcitrant Priapism in a Pediatric Patient.

Although rare in pediatrics, ischemic priapism carries significant risk of erectile dysfunction if not treated promptly. We report a case of idiopathic ischemic priapism in a male aged 14 years, refractory to traditional therapies, including aspiration/irrigation, phenylephrine injection, and distal shunt. However, the priapism resolved after intracavernosal injections of tissue plasminogen activator (tPA) with preservation of normal erectile function. To our knowledge, this is the first reported case of intracavernosal tPA for treatment of pediatric priapism. tPA may be a useful management option for recalcitrant ischemic priapism in pediatric patients and may prevent devastating outcomes such as lifelong erectile dysfunction.

Bedside ultrasound in pediatric critical care: a review.

OBJECTIVE: Bedside ultrasound, as performed by the intensivist, is gaining in popularity and has become a powerful tool to understand the physiological state of the critically ill patient and to decrease procedural risks. This review assesses clinical applications of bedside ultrasound in the pediatric intensive care unit. DESIGN: A literature review was conducted to identify English language studies in Pubmed as of June, 2010, using combinations of the following search terms: 'pediatric,' 'ultrasound,' 'critical care,' and 'intensive care.' Examination of reference lists of these studies yielded additional studies. Studies were reviewed by both authors. SETTING: Intensive care unit, emergency department, or operating rooms, as relevant to application of bedside ultrasound in the pediatric intensive care unit. PATIENTS/SUBJECTS: Pediatric patients (age 0-18 yrs) with adult patients (>18 yrs) in relevant studies utilizing bedside ultrasound by the treating clinician. INTERVENTIONS: Bedside ultrasound by treating clinician. MEASUREMENTS: Variable, per individual studies. MAIN RESULTS/CONCLUSIONS: Bedside ultrasound, as practiced by the pediatric intensivist, has the potential to improve pediatric critical care medicine, but data supporting its use is limited. Further studies are needed to explore applications, with specific emphasis on the training and experience of ultrasound operators. There is a need for a standardized educational curriculum, and questions remain as to the optimal mode of education and quality assurance of ultrasound operators.

Development, Implementation, and Evaluation of a Faculty Development Workshop to Enhance Debriefing Skills Among Novice Facilitators.

Introduction Effective debriefing during simulation-based training (SBT) is critical to promote learning outcomes. Despite debriefing's central role in learning and various published debriefing methods and techniques, little is known about faculty development structure for debriefing training among novice facilitators. Continuing medical education courses often use simulation-based methods but provide minimal training in debriefing techniques to novice facilitators. We describe the development, implementation, and evaluation of a structured debriefing training workshop for novice facilitators. Methods Designed and conducted by simulation debriefing experts, a debriefing workshop was provided to novice facilitators serving as faculty during the simulation-based Sedation Provider Course (PC) at the 2018 Society of Pediatric Sedation conference. Emphasizing evidence-based key elements of effective debriefing, the workshop was divided into three components: 1) an introductory 30 minute didactic, 2) 75 minutes role modeling of simulated effective and ineffective debriefing 3) 120 minutes repetitive deliberate practice sessions with summative and formative feedback. Effective transfer of learned debriefing skills was assessed during facilitators' PC debriefing using the Objective Structured Assessment of Debriefing (OSAD) tool, facilitators' self-efficacy, and PC student learners' evaluation of facilitator debriefings during the PC. Results Sixteen facilitators participated in the 4-h workshop and the next day served as PC faculty. The median OSAD score was 31 (13-40) for all facilitators. OSAD components with lowest and highest performance were "Establishing Learning Environment" with a median score of 1 (1-5) and "Engagement of Learners," with a median score of 4.75 (2.5-5). Facilitators' self- assessment in debriefing significantly improved on the 5-point Likert scale pre- and post-workshop, respectively. PC student learners' evaluations revealed high degrees of satisfaction with debriefing quality. Conclusions A proposed model integrating full-length debriefing and repetitive practice paired with summative and formative feedback provides a feasible and effective approach for debriefing training of novice facilitators for simulation-based educational courses.

Prevalence of Errors in Anaphylaxis in Kids (PEAK): A Multicenter Simulation-Based Study.

BACKGROUND: Multi-institutional, international practice variation of pediatric anaphylaxis management by health care providers has not been reported. OBJECTIVE: To characterize variability in epinephrine administration for pediatric anaphylaxis across institutions, including frequency and types of medication errors. METHODS: A prospective, observational, study using a standardized in situ simulated anaphylaxis scenario was performed across 28 health care institutions in 6 countries. The on-duty health care team was called for a child (patient simulator) in anaphylaxis. Real medications and supplies were obtained from their actual locations. Demographic data about team members, institutional protocols for anaphylaxis, timing of epinephrine delivery, medication errors, and systems safety issues discovered during the simulation were collected. RESULTS: Thirty-seven in situ simulations were performed. Anaphylaxis guidelines existed in 41% (15 of 37) of institutions. Teams used a cognitive aid for medication dosing 41% (15 of 37) of the time and 32% (12 of 37) for preparation. Epinephrine autoinjectors were not available in 54% (20 of 37) of institutions and were used in only 14% (5 of 37) of simulations. Median time to epinephrine administration was 95 seconds (interquartile range, 77-252) for epinephrine autoinjector and 263 seconds (interquartile range, 146-407.5) for manually prepared epinephrine (P = .12). At least 1 medication error occurred in 68% (25 of 37) of simulations. Nursing experience with epinephrine administration for anaphylaxis was associated with fewer preparation (P = .04) and administration (P = .01) errors. Latent safety threats were reported by 30% (11 of 37) of institutions, and more than half of these (6 of 11) involved a cognitive aid. CONCLUSIONS: A multicenter, international study of simulated pediatric anaphylaxis reveals (1) variation in management between institutions in the use of protocols, cognitive aids, and medication formularies, (2) frequent errors involving epinephrine, and (3) latent safety threats related to cognitive aids among multiple sites.

Workplace-Based Assessments Using Pediatric Critical Care Entrustable Professional Activities.

BACKGROUND: Workplace-based assessment (WBA) is critical to graduating competent physicians. Developing assessment tools that combine the needs of faculty, trainees, and governing bodies is challenging but imperative. Entrustable professional activities (EPAs) are emerging as a clinically oriented framework for trainee assessment. OBJECTIVE: We sought to develop an EPA-based WBA tool for pediatric critical care medicine (PCCM) fellows. The goals of the tool were to promote learning through benchmarking and tracking entrustment. METHODS: A single PCCM EPA was iteratively subdivided into observable practice activities (OPAs) based on national and local data. Using a mixed-methods approach following van der Vleuten's conceptual model for assessment tool utility and Messick's unified validity framework, we sought validity evidence for acceptability, content, internal structure, relation to other variables, response process, and consequences. RESULTS: Evidence was gathered after 1 year of use. Items for assessment were based on correlation between the number of times each item was assessed and the frequency professional activity occurred. Phi-coefficient reliability was 0.65. Narrative comments demonstrated all factors influencing trust, identified by current literature, were cited when determining level of entrustment granted. Mean entrustment levels increased significantly between fellow training years (P = .001). Compliance for once- and twice-weekly tool completion was 50% and 100%, respectively. Average time spent completing the assessment was less than 5 minutes. CONCLUSIONS: Using an EPA-OPA framework, we demonstrated utility and validity evidence supporting the tool's outcomes. In addition, narrative comments about entrustment decisions provide important insights for the training program to improve individual fellow advancement toward autonomy.

Exploring the thesis experience of Master of Health professions education graduates: a qualitative study.

OBJECTIVES: To explore the thesis experience of recent Master of Health Professions Education (MHPE) graduates in the University of Illinois at Chicago (UIC) program. METHODS: This is a qualitative case study exploring the experience of MHPE graduates between 2014 and 2016 (n=31). Using convenience sampling, all graduates with an email address (n=30) were invited to participate in an online survey and semi-structured interviews. Interviews were completed in-person or via telephone or video conference; interviewers collected detailed notes and audio recordings.  Two authors independently analyzed the data iteratively using thematic analysis and discrepancies were discussed and resolved. RESULTS: Survey results (n=20, 67%) revealed an average graduation of 5.1 years; 10 graduates (33%) were interviewed. Three themes related to the thesis experience were identified: success factors, challenges, and outcomes. Success factors, when present, promoted completion of a thesis; these included: a supportive program environment, time management, available resources, MHPE foundational coursework, aligning theses with career goals, and identifying a project with limited scope. Challenges made thesis completion more difficult for graduates; these included: institutional factors, personal or professional responsibilities, burnout, externally-imposed deadlines, and barriers in the research process. Despite these challenges, completing the thesis resulted in many professional or personal benefits (outcomes). CONCLUSIONS: Multiple success factors and challenges were identified in the master's thesis process among MHPE graduates at UIC. These findings can help students conducting education-based scholarship through the master's thesis process. This study also informs program evaluation and improvements and outlines personal and professional outcomes of completing a master's thesis.

Pediatric pyogenic sacroiliitis and osteomyelitis.

Pyogenic sacroiliitis accounts for 1-2% of all cases of septic arthritis with less than 200 cases reported in the English literature since the beginning of the twentieth century. Cultures of joint fluid usually grow Staphylococcus aureus. Prognosis is excellent; however, diagnosis may be difficult due to rarity of disease and non-specific signs, symptoms, and physical findings. Magnetic resonance imaging has been found to be the most useful imaging modality in diagnosis. Most reported cases required prolonged antimicrobial therapy of six to nine weeks. Presented here are two children with pyogenic sacroiliitis managed at a tertiary-care, university hospital and review of the literature on this relatively rare diagnosis.
