Percutaneous Electrical Nerve Field Stimulation for Drug-Refractory Pediatric Cyclic Vomiting Syndrome.

BACKGROUND: Cyclic vomiting syndrome (CVS) is a disabling condition frequently refractory to pharmacologic therapy. The aim of this study was to evaluate the effects of noninvasive, auricular percutaneous electrical nerve field stimulation (PENFS) as prophylactic therapy for pediatric CVS. METHODS: Children 8-18 years with drug-refractory CVS were prospectively enrolled from a tertiary care CVS clinic. Subjects received 6 consecutive weeks of PENFS. CVS severity was quantified by episode frequency and duration score (range 0-25) at baseline and at extended follow-up (4-6 months after end of therapy). Response was classified as ≥50% improvement in either frequency or duration of attacks at extended follow-up. Subjects also completed validated surveys of nausea, disability, and global response. RESULTS: Thirty subjects completed the study. Median (interquartile range, IQR) age was 10.5 (8.5-15.5) years; 60% were female. At follow-up, 80% met criteria for treatment response with a median (IQR) response duration of 113 (61-182) days. The frequency-duration score improved from baseline median (IQR) 12.0 (9.0-16.0) to 3.0 (1.0-6.0) at follow-up, P < 0.0001. Median (IQR) nausea and disability scores decreased from baseline to week 6: 2.1 (1.3-2.7) to 0.9 (0-1.6), P = 0.003 and 47.5 (41.0-53.0) to 38.0 (16.0-51.0), P = 0.001, respectively. At end of therapy, 66% and 55% patients reported global response of at least "moderately better" and "a good deal better," respectively. There were no serious side effects. CONCLUSIONS: This study suggests long-term benefits of PENFS for children with CVS. PENFS improves several disabling aspects of CVS, including episode frequency, duration, and functional disability.

Characteristics of high-resolution esophageal manometry in children without dysphagia.

BACKGROUND: The absence of high-resolution esophageal manometry (HREM) norms in pediatrics limits the assessment of children with dysphagia. This study aimed to describe HREM parameters in a cohort of children without dysphagia. METHODS: Children ages 9-16 years with a negative Mayo Dysphagia Questionnaire screen and normal histologic findings underwent HREM after completion of esophagogastroduodenoscopy. Ten swallows of 5 ml 0.45% saline boluses per subject were captured in supine position. Analyzed data included resting and integrated relaxation pressures (IRP) of lower (LES) and upper (UES) esophageal sphincters, peristaltic contractile integrals, transition zone (TZ) breaks, velocities, and lengths associated with proximal and distal esophagus. KEY RESULTS: 33 subjects (15 female) with mean (range) age 12.9 (9-16) years completed the study. Two of 330 analyzed swallows failed. The UES mean resting pressure, and its 0.2 s and 0.8 s IRPs were 48.3 (95% CI 12.9) mmHg, 2.9 (95% CI 1.9) mmHg, and 12.1 (95% CI 2.5) mmHg, respectively. The LES mean resting pressure and its 4 s IRP were 29.0 (95% CI 4.0) mmHg and 9.2 (95% CI 1.3) mmHg. The mean proximal (PCI) and distal (DCI) esophageal contractile integrals were 231 (95% CI 54.8) mmHg-s-cm and 1789.3 (95% CI 323.5) mmHg-s-cm, with mean TZ break 0.5 (95% CI 0.3) cm. CONCLUSIONS & INFERENCES: This is the first study to describe HREM parameters in children without dysphagia. Most of the reported measurements were significantly different and less variable from reported adult norms. This emphasizes the need for child-specific catheters, norms, and protocols to define pediatric esophageal motility disorders.

Gastric emptying in healthy children using the Spirulina breath test: The impact of gender, body size, and pubertal development.

BACKGROUND: There are no pediatric norms for gastric emptying (GE) measured by nuclear scintigraphy. The 13 C-labeled, stable isotope GE breath test (GEBT) is a non-radioactive alternative. We aimed to determine normative GEBT ranges in a cohort of healthy children and examine the influence of age, gender, puberty, and body surface area (BSA). METHODS: Healthy children ages 8-18 years completed the [13 C]-Spirulina platensis GEBT after an overnight fast. Breath samples were collected at baseline, every 15 min × 1 h, then every 30 min for 4 h total. The 13 CO2 excretion rate was determined by the change in 13 CO2 /12 CO2 over time in each breath sample, expressed as kPCD (Percent 13 C Dose excreted/min). A mixed model with random time was used for multivariable analysis and outcome fit into a quadratic model. KEY RESULTS: The 100 subjects completed the test meal within allotted time. Median (IQR) age was 13.5 (11.3-15.5) years; 51% were female. Females had lower 13 CO2 excretion rates (slower GE) than males across time (p < 0.001) while decreased excretion rates correlated with higher BSA (p = 0.015). Gender differences were also noted within pubertal stages with females showing slower GE. Multivariable analysis suggested that pre-pubertal children have faster GE than both peri- and post-pubertal groups (p < 0.0001). CONCLUSIONS & INFERENCES: Gender, puberty, and BSA influence GE rates in healthy children more than age. Although further data are needed, pubertal stage and hormonal influences may be unique factors to consider when assessing GE in children.

Engaging Parents in Education for Discharge (ePED): Evaluating the Reach, Adoption & Implementation of an Innovative Discharge Teaching Method.

PURPOSE: This paper describes the evaluation of the implementation of an innovative teaching method, the "Engaging Parents in Education for Discharge" (ePED) iPad application (app), at a pediatric hospital. DESIGN AND METHODS: The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to guide the evaluation. Three of the five RE-AIM elements are addressed in this study: Reach, Adoption, and Implementation. RESULTS: The Reach of the ePED was 245 of 1015 (24.2%) patient discharges. The Adoption rate was 211 of 245 (86%) patients discharged in the five months' study period. High levels of fidelity (89.3%) to Implementation of the ePED were attained: the Signs and Symptoms domain had the highest (93%) and Thinking Forward about Family Adjustment screen had the lowest fidelity (83.3%). Nurse themes explained implementation fidelity: "It takes longer", and "Forgot to do it." CONCLUSIONS: The ePED app operationalized how to have an engaging structured discharge conversation with parents. While the Reach of the ePED app was low under the study conditions, the adoption rate was positive. Nurses were able to integrate a theory-driven practice change into their daily routine when using the ePED app. IMPLICATIONS FOR PRACTICE: The rates of adoption and implementation fidelity support the feasibility of future hospital wide implementation to improve patient and family healthcare experience. Attention to training of new content and the interactive conversation approach will be needed to fully leverage the value of the ePED app. Future studies are needed to evaluate the maintenance of the ePED app.

Using the Engaging Parents in Education for Discharge (ePED) iPad Application to Improve Parent Discharge Experience.

PURPOSE: The purpose of this study was to evaluate the use of the Engaging Parents in Education for Discharge (ePED) iPad application on parent experiences of hospital discharge teaching and care coordination. Hypotheses were: parents exposed to discharge teaching using ePED will have 1) higher quality of discharge teaching and 2) better care coordination than parents exposed to usual discharge teaching. The secondary purpose examined group differences in the discharge teaching, care coordination, and 30-day readmissions for parents of children with and without a chronic condition. DESIGN/METHODS: Using a quasi-experimental design, ePED was implemented on one inpatient unit (n = 211) and comparison group (n = 184) from a separate unit at a pediatric academic medical center. Patient experience outcome measures collected on day of discharge included Quality of Discharge Teaching Scale-Delivery (QDTS-D) and care coordination measured by Care Transition Measure (CTM). Thirty-day readmission was abstracted from records. RESULTS: Parents taught using ePED reported higher QDTS-D scores than parents without ePED (p = .002). No differences in CTM were found between groups. Correlations between QDTS-D and CTM were small for ePED (r = 0.14, p 0.03) and non-ePED (r = 0.29, p < .001) parent groups. CTM was weakly associated with 30-day readmissions in the ePED group. CONCLUSION: The use of ePED by the discharging nurse enhances parent-reported quality of discharge teaching. PRACTICE IMPLICATIONS: The ePED app is a theory-based structured conversation guide to engage parents in discharge preparation. Nursing implementation of ePED contributes to optimizing the patient/family healthcare experience.
