Multidisciplinary Consensus on Curricular Priorities for Pediatric Neurocritical Care Nursing Education: A Modified Delphi Study in the United States.

BACKGROUND: Nurses are vital partners in the development of pediatric neurocritical care (PNCC) programs. Nursing expertise is acknowledged to be an integral component of high-quality specialty patient care in the field, but little guidance exists regarding educational requirements to build that expertise. We sought to obtain expert consensus from nursing professionals and physicians on curricular priorities for specialized PNCC nursing education in pediatric centers across the United States. METHODS: We used a modified Delphi study technique surveying a multidisciplinary expert panel of nursing professionals and physicians. Online surveys were distributed to 44 panelists over three rounds to achieve consensus on curricular topics deemed essential for PNCC nursing education. During each round, panelists were asked to rate topics as essential or not essential, as well as given opportunities to provide feedback and suggest changes. Feedback was shared anonymously to the panelist group throughout the process. RESULTS: From 70 initial individual topics, the consensus process yielded 19 refined topics that were confirmed to be essential for a PNCC nursing curriculum by the expert panel. Discrepancies existed regarding how universally to recommend topics of advanced neuromonitoring, such as brain tissue oxygenation; specialized neurological assessments, such as the serial neurological assessment in pediatrics or National Institutes of Health Stroke Scale; and some disease-based populations. Panelists remarked that not all centers see specific diseases, and not all centers currently employ advanced neuromonitoring technologies and skills. CONCLUSIONS: We report 19 widely accepted curricular priorities that can serve as a standard educational base for PNCC nursing. Developing education for nurses in PNCC will complement PNCC programs with targeted nursing expertise that extends comprehensive specialty care to the bedside. Further work is necessary to effectively execute educational certification programs, implement nursing standards in the field, and evaluate the impact of nursing expertise on patient care and outcomes.

Novel Serum Biomarkers Associated With Pediatric Hepatic Encephalopathy: A Systematic Review.

BACKGROUND: The pathophysiology of pediatric hepatic encephalopathy (HE) is not well understood. Various serum biomarkers associated with HE may provide insight into its pathology, but their use and interpretation in clinical practice for diagnosis and prognostication remain undetermined. We sought to investigate reported correlations of serum biomarkers with presence and degree of HE in children. METHODS: We conducted a systematic review of studies examining novel serum biomarkers and cytokines in association with HE that included children on PubMed, Embase, Lilacs, and Scopus. We utilized Covidence for abstract and text review by 2 independent reviewers for each study. RESULTS: We reviewed 2824 unique publications; 15 met criteria for inclusion. Categories of biomarkers reported were inflammatory cytokines, products of amino acid metabolism, trace elements and vitamins, and hepatic and neuro biomarkers. Of 19 individual biomarkers, only 5 were measured in more than 1 study. Elevations in interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were most commonly reported as associated with HE. Notably, we observed lower average IL-6 and TNF-alpha levels in pediatric-only studies compared to mixed age studies. Overall, high bias and poor applicability to our review question was observed. We encountered low numbers of studies with pediatric focus, and few conducted with low bias study designs. CONCLUSION: Investigated biomarkers span a large range of categories and suggest potentially useful correlations with HE. Further well-designed prospective biomarker research is necessary to better elucidate the pathogenesis of HE in children and improve early detection and clinical care.

Agreement between noninvasive oscillometric and invasive intra-arterial blood pressure in children with ruptured brain arteriovenous malformations.

BACKGROUND: Divergence between intra-arterial catheters blood pressure (ABP) and noninvasive oscillometry (NIBP) may affect the care of children with brain arteriovenous malformations (bAVMs). We described the agreement between ABP and NIBP in these children. METHODS: We conducted a retrospective review of patients admitted to the pediatric intensive care unit between 2017 and 2023 with bAVM rupture. Paired ABP and NIBP measurements were collected. Bland-Altman analyses were used to assess agreement. Correlation analysis was conducted between higher ABP and divergence between systolic BP (SBP) measurements. Hypertension was defined as mean arterial pressure (MAP) exceeding age-based 95th percentile. RESULTS: Thirty-four patients with 1901 BP pairs were observed. Bias overall was acceptable, but standard deviation (SD) was high. The best agreement of MAP was in non-hypertensive (bias 1.23 mmHg, SD 8.03 mmHg) and radial arterial catheters (bias 1.83 mmHg, SD 9.08 mmHg) subgroups. Bias for SBP was higher in hypertension (10.98 mmHg) and in infratentorial bAVMs (7.42 mmHg), suggesting poorer agreement in these subgroups. There were significant correlations between intra-arterial MAP and SBP divergence (R = +0.346, p<.001) and between intra-arterial SBP and SBP divergence (R = +0.677, p<.001), suggesting divergence widens with higher BP. Around 25 % of measurement pairs diverged to where one measurement crossed the clinical threshold for treatment, while the other did not, with ABP being more frequently higher than NIBP. CONCLUSIONS: There is good agreement between ABP and NIBP, particularly in non-hypertensive ranges and with radial arterial catheters. Measurements, however, diverge in hypertension. Further research must define age-based thresholds, validate methods of BP measurement, and determine the effect of BP reduction on outcomes in these children.

A Multifaceted Intervention to Improve Teamwork on an Inpatient Pediatric Neurosurgery Service.

BACKGROUND: Increased safety reports related to interprofessional teamwork on an acute care unit at a quaternary children's hospital prompted a teamwork-focused improvement effort on the pediatric neurosurgery service. METHODS: An interprofessional workgroup was formed and met twice monthly throughout the project. A survey using modified validated items was disseminated to pediatric neurosurgery nurses, advanced practice providers (APPs), and physicians in March 2021 to identify opportunities for improvement. Structured debriefs on survey results promoted discourse on teamwork. The researchers implemented two interventions: (1) nursing-centered interprofessional education and (2) a rounding checklist before redistributing the survey in December 2021. RESULTS: Baseline and follow-up survey response rates were 84.1% (58/69) and 71.4% (50/70), respectively. Nurses at baseline perceived lower teamwork scores for 12 items compared to physicians and APPs (p < 0.05). Nurse perceptions improved after interventions in: "using 'we' rather than 'they'" (21.3% vs. 51.2% agree, p = 0.003), "I am confident that this team works effectively" (46.8% vs. 80.5%, p = 0.001), "shared understanding of each other's role on the team" (48.9% vs. 73.2% agree, p = 0.02), and "getting others on the team to listen" (46.8% vs. 75.6%, p = 0.004). Mean teamwork effectiveness improved from 4.12 to 5.25 (out of 7; p < 0.0001). Nurses ranked three interventions as most effective: interprofessional training (35/41, 85.4%), educational clinical pearls (14/41, 34.1%), and structured opportunities to discuss teamwork (10/41, 24.4%). CONCLUSION: Interprofessional training, a teamwork survey, and structured debriefing improved nurse perceptions of teamwork. Interventions targeting social components of change can improve teamwork even without process changes.

Sustainability of a Pediatric Neurointensive Care Unit Model Within a Mixed Pediatric Intensive Care Unit and Its Effect on Nursing Sentiment.

ABSTRACT: BACKGROUND: Pediatric neurocritical care (PNCC) and pediatric neurointensive care units (neuro-PICU) are growing fields. Although some institutions have established independent neuro-PICUs meeting most Neurocritical Care Society (NCS) standards for neurocritical care units, many centers lack the resources to do so. We describe an alternative neuro-PICU model as a designated unit within a mixed pediatric intensive care unit (PICU) and its effects on nursing sentiment. METHODS: We established a 6-bed neuro-PICU within a 36-bed noncardiac PICU. Charge nurses were tasked with admitting PNCC patients into these beds. For nursing expertise, we used a core group of 12 PNCC specialty nurses and instituted PNCC nursing education to PICU nurses. We observed the number of PNCC patients admitted to neuro-PICU beds and surveyed charge nurses to identify barriers to assigning patients. We surveyed PICU nursing staff to explore sentiment regarding PNCC before and after establishing the neuro-PICU. Nursing criteria were compared with NCS standards. RESULTS: In the 40-month period, our PICU saw 2060 PNCC admissions. Overall, occupied neuro-PICU beds housed PNCC patients 74.1% of the time. The biggest barriers to patient placement were too many competing placement requests, not enough neuro-PICU beds when specialty census was high, and difficulty assigning one nurse to two PNCC patients. In surveys after establishing the neuro-PICU, compared to before, experienced nurses reported being more interested in obtaining Emergency Neurological Life Support certification (94.2% vs 80.6%, P = .0495), and inexperienced nurses reported being more familiar with PNCC clinical pathways (53.5% vs 31.7%, P = .0263). Most NCS criteria related to nursing organization were met. CONCLUSIONS: Focused neuro-PICUs should be developed to complement advances in the field of PNCC. Alternative neuro-PICU models are possible and can increase nursing interest in further education and awareness of clinical pathways, but barriers exist that require institutional commitment to nursing development to sustain the delivery of specialized care to this population.

Effect of clevidipine on intracranial pressure in pediatric neurosurgical patients: a single-center retrospective review.

OBJECTIVE: Hemodynamic management in pediatric neurosurgical patients is essential for maintaining cerebral perfusion pressure (CPP), avoiding hemorrhage, and preventing secondary neurological injury. Antihypertensive infusions approved for pediatrics are not widely studied in the pediatric neurosurgical population and may have adverse effects on intracranial pressure (ICP), contributing to reduced CPP. Clevidipine is an ultra-rapid-acting intravenous antihypertensive agent used for hemodynamic control in adult surgical patients. In pediatric patients, clevidipine is safe and effective in controlling blood pressure in the perioperative period, although studies evaluating its effect on ICP in neurosurgical patients are lacking. The objective of this research was to evaluate the effect of clevidipine on ICP in pediatric neurosurgical patients. METHODS: This single-center retrospective study involved patients admitted to the pediatric ICU between January 1, 2017, and December 31, 2020. Patients eligible for inclusion had ICP monitoring devices and received clevidipine infusion for a minimum of 6 hours postoperatively, with at least one ICP measurement pre- and postinfusion. Excluded patients had an elevated preinfusion ICP > 20 mm Hg. The primary outcome was the average change in ICP from preinfusion baseline to hours 6 to < 12, 12 to < 24, and 24 to < 48 of clevidipine infusion. Secondary outcomes included frequency of ICP measurements > 20 mm Hg, CPP measurements < 50 mm Hg, treatment failure defined by a need for concurrent antihypertensive infusion, and frequency of elevated serum triglycerides > 200 mg/dL. Descriptive data were expressed as frequency with percentage or median with interquartile range as appropriate. Analysis of continuous outcome variable data involved Mann-Whitney U-tests with an alpha significance of 0.05. RESULTS: Data from 47 patients were included in the analysis. The average change in ICP from preinfusion baseline to 48 hours was < 1 mm Hg. Of 3025 total postinfusion ICP measurements in 47 patients, 67 measurements (2.2%) in 13 patients (28%) were > 20 mm Hg. CPP measurements < 50 mm Hg occurred in 16 of 45 patients (36%). Three patients (6.4%) required use of a secondary antihypertensive medication infusion, and 5 of 14 patients (36%) had serum triglycerides > 200 mg/dL. CONCLUSIONS: Use of clevidipine had minimal effect on ICP. The results of this study suggest that clevidipine is effective at safely maintaining ICP and CPP measurements without detrimental adverse effects in pediatric neurosurgical patients.

Knowledge and Practice Gaps in Pediatric Neurocritical Care Nursing: Lessons Learned From a Specialized Educational Boot Camp.

OBJECTIVES: Pediatric neurocritical care (PNCC) is a quickly growing subspecialty within pediatric critical care medicine. Standards for care, education, and application of neuromonitoring technologies in PNCC are still being developed. We sought to identify and improve knowledge deficits in neurocritical care with an educational boot camp for nurses. SETTING: Quaternary children's hospital with 36 PICU beds. DESIGN: Preinterventional and postinterventional study. METHODS: A 2-day boot camp course covering neurologic and neurosurgical topics pertinent to PNCC was provided to 46 pediatric acute and critical care nurses divided into three cohorts over 3 years. Participant characteristics were collected, and precourse and postcourse knowledge assessments were administered. RESULTS: Regarding participant characteristics, neither critical care registered nurse certification nor years of nursing experience were associated with better precourse baseline knowledge. Knowledge gaps spanned bedside neurologic assessments, physiologic goals in brain injury, and side effects of neurocritical care medications. In postcourse assessments, all participants showed improvement in scores, and most participants sustained improvements after 6 months. Nurses reported significant improvement in self-reported confidence in caring for the PNCC population. We also observed shorter ICU lengths of stay, decreased hospital incident reports, and decreased time to stroke imaging, although these programmatic metrics cannot be credited to nursing education alone. CONCLUSIONS: PNCC programs should include nursing expertise in the field. However, topics specific to PNCC may not be adequately addressed by existing general critical care nursing education and certification. A multimodal educational boot camp can be an effective method to improve nursing knowledge in PNCC. Our results demonstrate that specialty nursing education in PNCC is both innovative and feasible, with the potential to improve patient care. Further research is needed to determine the benefits of specialty education on quality of care and clinical outcomes.

Brain abscess caused by Trueperella bernardiae in a child.

BACKGROUND: Recurrent intracranial abscesses secondary to refractory otitis media present a challenge which demands multidisciplinary collaboration. CASE DESCRIPTION: We present the first known case of pediatric brain abscess caused by a polymicrobial infection of Trueperella bernardiae, Actinomyces europaeus, and mixed anaerobic species resulting from acute-on-chronic suppurative left otitis media. This patient required two separate stereotactic abscess drainages and a complex course of antibiotics for successful management. CONCLUSION: Surgery is essential in the management of cerebral abscess both in agent identification and therapeutic drainage. Management of abscesses secondary to unusual and polymicrobial organisms often requires consultation from other medical and surgical specialties.

Diffusion Tensor Imaging in an Infant Undergoing Functional Hemispherectomy: A Surgical Aid.

Hemispherectomy is a highly effective treatment option for children with severe, unilateral, medically refractory epilepsy. Many patients undergoing hemispherectomy are younger patients with dysmorphic brains, making accomplishing a complete disconnection challenging due to anatomic distortion, even with the aid of intraoperative navigation. Diffusion tensor imaging (DTI) has been proposed as a valuable imaging adjunct perioperatively to help guide surgeons intraoperatively, as well as for post-surgical evaluation and confirmation of complete hemispheric disconnection. We present a case of an infant with Otoharra syndrome and hemimegencephaly who underwent a functional hemispherectomy for treatment of severe, refractory seizures. We demonstrate how DTI was utilized both pre-, intra-, and postoperatively to help plan, guide, and confirm surgical disconnection. The application of exquisite DTI for this child led to her being seizure-free, which is a life-changing event with long-lasting benefits and will become even more critical as we now perform these disconnection procedures with a more minimally invasive approach.

Silver-Impregnated Dressings for Sternotomy Incisions to Prevent Surgical Site Infections in Children.

BACKGROUND: The consequences of surgical site infections can be severe and range from short-term delays in discharge from the hospital to life-threatening infections such as mediastinitis. OBJECTIVES: To evaluate the effectiveness of silver-impregnated dressings in decreasing surgical site infections in children after cardiac surgery. METHODS: A randomized, controlled trial was used to compare silver-impregnated dressings (59 participants) with standard dressings (58 participants). The study team supervised all dressing changes after a sternotomy and ensured adherence with the hospital's bundle for reduction of surgical site infections. The ASEPSIS tool was used to evaluate sternal wounds for evidence of infection. RESULTS: The 2 groups had comparable Risk Adjustment for Congenital Heart Surgery scores, age, sex, weight, height, operating room characteristics, and number of chest tubes and/or pacemaker wires. No surgical site infections occurred in any study participant. Infections did occur, however, during the same period, in cardiac surgical patients who were not enrolled in the study. CONCLUSIONS: The evidence did not support the superiority of silver-impregnated dressings for prevention of surgical site infections in children after cardiac surgery. Adherence to a bundle for prevention of surgical site infections may have decreased the incidence of such infections in the study population during the study period.
