Missed opportunities during pediatric residency training: report of a 10-year follow-up survey in critical care transport medicine.

Objectives The Accreditation Council for Graduate Medical Education requires pediatric residency training programs to provide exposure to the prehospital management and transport of patients. The authors hypothesized that compared with a similar study a decade prior, current pediatric residency training programs have reduced requirements for participation in transport medicine, thus reducing further the opportunities for residents to learn the management of critically ill infants and children. Methods In 2009, a questionnaire was distributed to 182 pediatric residency program directors. The authors obtained information regarding the neonatal and pediatric transport teams, the training program size, and the pediatric residents’ role in the transport team. Results Sixty-eight (37%) of the 182 surveyed institutions responded. Residents were involved in neonatal and pediatric transports in 42.8% and 55.0% of programs, respectively. When involved in transports, residents were the neonatal and pediatric team leaders 44.4% and 42.4% of the time, respectively. Evaluation of resident transport performance occurred consistently in only 23.3% (neonatal) and 21% (pediatric) of programs. Most programs (90.3%) endorsed the concept of a curriculum that would uniquely provide an integrated experience in critical care transport to increase resident exposure, competence, and confidence. Conclusions Pediatric residency participation in neonatal and pediatric critical care transport continued to decline among training programs. Residents participating in transports were less likely to function as team leaders and frequently did not receive performance evaluations. Most respondents welcomed a curriculum that would increase residents’ exposure to the critically ill infants and children transported by neonatal and pediatric teams.

Risk Factors for Failed Tracheal Intubation in Pediatric and Neonatal Critical Care Specialty Transport

Abstract Objective. Nearly 200,000 pediatric and neonatal transports occur in the United States each year with some patients requiring tracheal intubation. First-pass intubation rates in both pediatric and adult transport literature are variable as are the factors that influence intubation success. This study sought to determine risk factors for failed tracheal intubation in neonatal and pediatric transport. Methods. A retrospective chart review was performed over a 2.5-year period. Data were collected from a hospital-based neonatal/pediatric critical care transport team that transports 2,500 patients annually, serving 12,000 square miles. Patients were eligible if they were transported and tracheally intubated by the critical care transport team. Patients were categorized into two groups for data analysis: (1) no failed intubation attempts and (2) at least one failed intubation attempt. Data were tabulated using Epi Info Version 3.5.1 and analyzed using SPSSv17.0. Results. A total of 167 patients were eligible for enrollment and were cohorted by age (48% pediatric versus 52% neonatal). Neonates were more likely to require multiple attempts at intubation when compared to the pediatric population (69.6% versus 30.4%, p = 0.001). Use of benzodiazepines and neuromuscular blockade was associated with increased successful first attempt intubation rates (p = 0.001 and 0.008, respectively). Use of opiate premedication was not associated with first-attempt intubation success. The presence of comorbid condition(s) was associated with at least one failed intubation attempt (p = 0.006). Factors identified with increasing odds of at least one intubation failure included, neonatal patients (OR 3.01), tracheal tube size ≤ 2.5 mm (OR 3.78), use of an uncuffed tracheal tube (OR 6.85), and the presence of a comorbid conditions (OR 2.64). Conclusions. There were higher rates of tracheal intubation failure in transported neonates when compared to pediatric patients. This risk may be related to the lack of benzodiazepine and neuromuscular blocking agents used to facilitate intubation. The presence of a comorbid condition is associated with a higher risk of tracheal intubation failure.

The impact of postintubation chest radiograph during pediatric and neonatal critical care transport.

Objectives: Tracheal intubation is necessary in the setting of pediatric/neonatal critical care transport but information regarding usefulness and efficiency of a confirmatory postintubation chest radiograph is limited. We hypothesize that routine postintubation chest radiograph to confirm tracheal tube position is not informative and can be eliminated to improve efficiency without compromising safety in transport. Design: This was a prospective observational study. The primary study outcome was the rate of tracheal tube repositioning after postintubation chest radiograph and the secondary outcome was the on-scene time. Additional data obtained included the initial accuracy of tracheal tube depth based on Pediatric Advanced Life Support and Neonatal Resuscitation Program guidelines. Setting: A children’s hospital-based pediatric/neonatal critical care transport team in northeastern Ohio. Patients: All pediatric/neonatal patients intubated by the transport team during the 18-month study period (January 2009—July 2010). Measurements and Main Results: There were 77 patients enrolled (43 pediatric, 34 neonatal). A postintubation chest radiograph was obtained 85.7% of the time and showed tracheal tube malposition in 47% of cases. No difference was seen in the rate of malpositioned tracheal tubes in the neonatal group compared with pediatric group (51.7% vs. 43.2%, p = 0.54). The calculated tracheal tube depth based on the Neonatal Resuscitation Program and Pediatric Advanced Life Support guidelines was correct in 50% of the neonates and 41.9% of the pediatric patients. In patients with appropriate initial tracheal tube depth by calculations, the tracheal tube was repositioned at similar rates after postintubation chest radiograph in both neonatal and pediatric patients (50% vs. 41.9%, p = 0.48). When comparing mean onscene times for patients with/without a postintubation chest radiograph, the neonatal patients saved 33 minutes on average when no chest radiograph was obtained (mean ± sd: 60.6 ± 35.8 min vs. 93.8 ± 23.8 min, p = 0.01). There was no statistical difference in on-scene time for pediatric patients whether they did or did not receive a postintubation chest radiograph. Conclusions: Although postintubation chest radiographs may extend the overall on-scene transport times in select patients, our data show that the postintubation chest radiographs remain informative in pediatric/neonatal critical care specialty transport and should be obtained when feasible.

Intubation in Pediatric/Neonatal Critical Care Transport: National Performance

Abstract Background: There are nearly 200,000 US infants/children transported annually for specialty care and there are no published best practices in transport intubation. Objective: Respiratory interventions are a priority in pediatric and neonatal critical care transport (PNCCT). A recent Delphi study identified intubation performance as an important PNCCT quality metric, though data are insufficient. The objective of the study is to determine multi-center rates of first attempt intubation success in pediatric/neonatal transport and identify practice processes associated with higher performing centers. Methods: Retrospective chart review where data was collected from the 9 participating centers over a 6-month period from January–June 2013. Data describing intubation training and practices were gathered using SurveyMonkey® (Palo Alto, CA). Data were tabulated in Microsoft Excel (Redmond, WA) and analyzed using descriptive statistics. Through the determination of 1st intubation success rate across multiple pediatric/neonatal critical care transport programs, we hypothesized that the features of higher and lower performing centers can be identified to inform practice. Results: 9 of 14 invited institutions participated. The median (IQR) 6-month transport volume for neonates(neo) was 289(35-646) and pediatric (ped) 510(122-831). On average, 7%(+/−3.0) of neo and 1.6%(+/−0.7) of ped transport patients required intubation. Individual centers had their initial success rate calculated and a 95% confidence interval was determined for those centers satisfying the np > 5 and n(1-p) > 5 sample size requirement for normality assumption of proportions. Since the overall success rate was 64%, it was determined that n = 14 initial intubation attempts would be the minimum number needed per center in order to fulfill the sample size requirement for normality assumption. Centers whose 95% confidence interval did not contain the initial overall success rate were identified. Conclusion: This represents the first multi-center neo/ped intubation dataset in PNCCT. First attempt intubation success lags behind reported anesthesia intubation rates but parallels pediatric emergency department intubation success rates. Training and operational processes are variable in PNCCT, though top performing teams require live-patient intubation success to achieve initial intubation competency.

Heliox in Children with Croup: A Strategy to Hasten Improvement

OBJECTIVE Upper airway obstruction is responsive to the reduction in airflow turbulence provided by helium/oxygen (heliox) admixture. Our pediatric critical care transport team (PCCTT) has used heliox for children with upper airway obstruction from croup. We sought to describe our experience with heliox on transport and hypothesized that heliox-treated children with croup would show a more rapid clinical improvement. METHODS Children with croup transported by our PCCTT and admitted to the PICU were evaluated. We analyzed pretransport care, transport interventions, and outcomes. Croup scores (Modified Taussig) were assigned retrospectively according to respiratory therapy charting. Data were analyzed using appropriate statistical tests, including Pearsons chi-square test, Fishers exact test, Mann-Whitney U rank comparison, and two-sample t-test. RESULTS Thirty-five children met inclusion criteria. Demographics were similar between groups. The pretransport medical care was similar between groups. Children receiving heliox had a higher baseline croup score [mean (SD) = 5.7(2.3) vs no heliox 2.9 (2.0), P < 0.001]. The improvement in croup scores over the first 60 minutes of transport was more rapid in the heliox-treated children (P < 0.001). There was no difference in the number of children requiring additional nebulized racemic epinephrine during transport. The PICU length of stay (P = 0.59) and hospital length of stay (P = 0.64) were similar between groups. CONCLUSION Heliox added to standard transport treatment for critically ill children with croup provides a more rapid improvement in croup scores. Heliox for croup during transport does not prolong intensive care unit stay. A prospective clinical trial is warranted to evaluate heliox in pediatric transport.

Specialty Pediatric Transport in Primary Care or Urgent Care Settings

OBJECTIVE We sought to describe a single centers experience with specialized critical care transport from non-hospital settings, including primary care offices and urgent care centers. We hypothesized that the majority of patients will require procedures outside the scope of practice of most EMS providers and will be better served by specialized pediatric critical care transport (SPCCT) teams. METHODS This study sought to retrospectively evaluate instances where children (0-18 years old) were transported by our SPCCT team from nonhospital settings, including primary care offices and urgent care centers, in 2009 and 2010. Data were extracted from a customized database and appropriate statistical tests were applied, including Fishers exact test for categorical comparisons and Mann-Whitney U test for non-parametric data comparisons. RESULTS Fifty-two patients were included. Most of the children were transported for respiratory distress (78%), and many were treated with albuterol (42%) and steroids (42%) prior to the SPCCT team arrival. The most common interventions performed by the SPCCT team were obtaining IV access and administering IV fluid boluses; 4 (7.7%) patients required advanced critical care treatments unique to SPCCT. Most patients (n = 34; 65%) were directly admitted to the general care floor, but a high number of patients (n = 12; 23%; PICU = 11, NICU = 1) required pediatric or neonatal intensive care unit admission. Only 3 patients (5.7%) were discharged home without hospital admission. For the 11 patients admitted to the PICU, the median length of stay (LOS) was 2.5 days (IQR 0.14-13.2). All patients survived to hospital discharge with an additional hospital LOS of 1.3 days (IQR 0.2-6.7). Patients were billed for these critical care transports an average of

From the street to the ICU: a review of pediatric emergency medical services and critical care transport

940. CONCLUSION Our small cohort demonstrates infrequent application of advanced critical care interventions beyond those provided by the referring primary care office or urgent care centers. This supports the practice of SPCCT teams providing transport services for select critically ill children at primary care offices and urgent care centers, but not as a standard practice for most pediatric patients in these settings.

Intubation Success in Critical Care Transport: A Multicenter Study

Crit Care Med 2016 • Volume 44 • Number 12 (Suppl.) and sepsis. Patients were prospectively enrolled in fluid strategy aiming to prevent fluid overload (preventive FS) and compared with subjects without that approach (conventional FS). Preventive FS: Maintenance intravenous fluid (MIVF) at 50% of calculated requirements. Resuscitation fluids were guided by pulse pressure variation. Conventional FS: MIVF according to Holiday-Segar formula and resuscitation according to surviving sepsis campaign guidelines. Primary outcome: percentage of FO(%FO) at 24, 48 and 72h. Secondary outcomes were MV duration, length of stay (LOS) as well as hemodynamic interventions; safety was assessed by renal function test and glycemia. Data in median and p25-p75. Results: 27 patients were included in Preventive FS (male 56%; 2 (1,4) mo) and 25 were reviewed for Conventional FS (male 59%; 7 (2,9) mo). Preventive FS had less %FO at 24h (3.4% v/s 0.9%, p< 0.05), less fluid resuscitation (0 (0,10) v/s 30 (18,40) ml/kg and PRBC transfusions(60% v/s 30%), all P-value <0.05. Mild hypoglycemia was more frequent in Preventive FS (14.8 v/s 0%, p< 0.05). Diuretics and its complications were more frequent in Conventional FS. Conventional FS was associated with longer MV duration (124 (96,141) v/s 63 (45,72). No significant differences were found in BUN, SCr and vasoactive drug support. Conclusions: Preventive FS was associated with significant less FO, less fluid resuscitation and PRBC transfusions, but mild hypoglycemia was more frequent. No other complications were found. Interestingly preventive FS was associated with shorter MV duration. Future studies are needed to develop interventions to prevent FO, but careful glucose infusion rate titration and hypoglycemia monitoring must be included.

Emergency Medical Services Utilization Is Associated With Community Deprivation in Children

Emergency medical services and critical care transport teams are relatively new parts of the American healthcare delivery system. Although most healthcare providers regularly interact with these groups and rely upon their almost ubiquitous availability, few know how these services developed or what sort of infrastructure currently exists to maintain them. This article provides a focused overview of the history and present practices of both emergency medical services and critical care transport teams, with a concentrated look at the implementation of these services in the pediatric population. Within this context, we also consider current challenges and future opportunities for both groups and conclude with ways to become involved in the improvement of out-of-hospital pediatric critical care.
