Achieving Enteral Autonomy in Children with Intestinal Failure Following Inpatient Admission: A Case Series.

We describe cases of intestinal failure wherein inpatient admission was critical toward enteral autonomy. We performed a retrospective chart review of 6 children with long-term parenteral nutrition dependence who were weaned from parenteral nutrition after admission. Admissions included feeding and medication titration, interdisciplinary care, and a home parenteral nutrition team consultation.

Virtual Telemedicine Visits in Pediatric Home Parenteral Nutrition Patients: A Quality Improvement Initiative.

BACKGROUND: Despite being less costly than prolonged hospitalization, home parenteral nutrition (HPN) is associated with high rates of post-discharge complications, including frequent readmissions and central line-associated bloodstream infections (CLABSIs). Telemedicine has been associated with improved outcomes and reduced healthcare utilization in other high-risk populations, but no studies to date have supported effectiveness of telemedicine in pediatric HPN. METHODS: We prospectively collected data on pediatric patients managed at a single HPN program who participated in postdischarge telemedicine visits from March 1, 2014 to March 30, 2016. We excluded patients with a history of HPN and strictly palliative care goals. Univariate analysis was performed for primary outcomes: Community-acquired CLABSI and 30-day readmission rate. RESULTS: Twenty-six families participated in the pilot initiative with median (interquartile range) patient age 1.5 (5.7) years old, diagnosis of short bowel syndrome in 16 (62%), and in-state residence in 17 (55%). Ishikawa (fishbone) diagram identified causes of post-discharge HPN complications. Areas of focus during telemedicine visit included central venous catheter care methods, materials, clinical concerns, and equipment. Compared to historical comparison group, the telemedicine group experienced CLABSI rates of 1.0 versus 2.7 per 1,000 line days and readmission rates of 38% versus 17% (p = 0.03, 0.02, respectively). CONCLUSIONS: Telemedicine visits identified opportunities for improvement for families newly discharged on HPN. In a small cohort of patients who experienced telemedicine visits, we found lower CLABSI rates alongside higher readmission rates compared with a historical comparison group. Further studies are needed to optimize telemedicine in delivering care to this high-risk population.

Administration of 4% tetrasodium EDTA lock solution and central venous catheter complications in high-risk pediatric patients with intestinal failure: A retrospective cohort study.

BACKGROUND: Selection of central venous catheter (CVC) lock solution impacts catheter mechanical complications and central line-associated bloodstream infections (CLABSIs) in pediatric patients with intestinal failure. Disadvantages of the current clinical standards, heparin and ethanol lock therapy (ELT), led to the discovery of new lock solutions. High-risk pediatric patients with intestinal failure who lost access to ELT during a recent shortage were offered enrollment in a compassionate use trial with 4% tetrasodium EDTA (T-EDTA), a lock solution with antimicrobial, antibiofilm, and antithrombotic properties. METHODS: We performed a descriptive cohort study including 14 high-risk pediatric patients with intestinal failure receiving 4% T-EDTA as a daily catheter lock solution. CVC complications were documented (repairs, occlusions, replacements, and CLABSIs). Complication rates on 4% T-EDTA were compared with baseline rates, during which patients were receiving either heparin or ELT (designated as heparin/ELT). RESULTS: Patients initiated 4% T-EDTA at the time they were enrolled in the compassionate use protocol. Use of 4% T-EDTA resulted in a 50% reduction in CVC complications, compared with baseline rates on heparin/ELT (incidence rate ratio: 0.50; 95% CI, 0.25-1.004; P = 0.051). CONCLUSION: In a compassionate use protocol for high-risk pediatric patients with intestinal failure, the use of 4% T-EDTA reduced composite catheter complications, including those leading to emergency department visits, hospital admissions, additional procedures, and mortality. This outcome suggests 4% T-EDTA has benefits over currently available lock solutions.

Ethanol lock therapy increases mechanical catheter complications in a pediatric intestinal failure population: A retrospective cohort study.

BACKGROUND: Ethanol lock therapy (ELT) decreases central line-associated bloodstream infections; however, the effect on mechanical catheter complications is unclear. In recent years, ELT has become unavailable for many patients, often resulting in high-risk patients switching back to heparin locks. We investigated the impact of ELT on mechanical catheter complications during this period. METHODS: We performed a retrospective cohort study of the Boston Children's Hospital intestinal rehabilitation program from January 1, 2018, to December 31, 2020. Pediatric patients with a central venous catheter requiring parenteral support for 3 months were included. The primary outcome was the composite rate of mechanical catheter complications (repairs and replacements). RESULTS: The pediatric intestinal failure cohort consisted of 122 patients. Forty-four percent received ELT for the entirety of the study period, 29% used only heparin locks, and 27% used ELT and heparin locks at different periods. During ELT use, there was 1.65 times the risk of mechanical catheter complications (composite outcome of repairs and replacements) compared with heparin locks (adjusted incidence rate ratio [aIRR] = 1.65, 95% CI = 1.18-2.31). Current ELT use was associated with 2.3 times the risk of catheter repairs (aIRR = 2.30, 95% CI = 1.36-3.89) but no significant increase in catheter replacement risk (aIRR = 1.41, 95% CI = 0.91-2.20). CONCLUSION: In the largest pediatric intestinal failure cohort evaluated to date, the use of ELT, compared with heparin locks, increased the risk of mechanical catheter complications. Mechanical complications carry morbidity requiring urgent clinic or emergency department visits and additional procedures. The investigation of alternative lock solutions is warranted.

Learning Gaps and Family Experience, Nurse-Facilitated Home Parenteral Nutrition Simulation-Based Discharge Training: Proof-of-Concept Study.

BACKGROUND: Home parenteral nutrition (HPN) is a life-sustaining therapy for children and adults suffering with severe digestive diseases, yet complications are commonplace, and predischarge trainings are variable. High-fidelity simulation training provides participants with an immersive experience using realistic equipment, supplies, and scenarios. Simulation training is rapidly becoming a potential gold standard for healthcare but is currently underutilized for families and caregivers. METHODS: We prospectively collected data on pediatric patients managed at a single HPN program from September 1, 2016, to September 30, 2018. Participants in a pilot simulation-based training program (orientation, high-fidelity mannequin, realistic homelike space, standardized clinical scenarios, and structured debriefing) were compared with historical controls. We excluded patients with short-term HPN use and strictly palliative goals of care. RESULTS: Nineteen (90%) families participated in the pilot initiative with a median (interquartile range) age of 0.9 (3.7) years and diagnosis of short-bowel syndrome in 14 (74%). During teaching scenarios, learning gaps were identified for aseptic needleless changes (53%), HPN equipment setup (84%) with specific difficulty adding multivitamin (32%), and dressing changes (63%). Thirty-day readmission rates in simulation-based training group vs historical cases were 42% vs 63% (P = not significant). There was no difference in length of stay between groups. All (100%) simulation-based training group participants would recommend this learning experience to others. CONCLUSION: HPN discharge training is a novel use for high-fidelity simulation to address family/caregiver satisfaction and to identify learning gaps. Further studies are needed to refine predischarge training materials and examine the impact on postdischarge outcomes.

Caregiver Training for Pediatric Home Parenteral Nutrition: A 5-Session Discharge Curriculum.

To maximize safety and the patient experience, caregivers require intensive training to administer home parenteral nutrition (HPN) before initial hospital discharge. This article provides the rationale, best practices, and a template for caregiver predischarge HPN education provided by nurses. The standardized HPN discharge curriculum is outlined over 5 didactic and hands-on sessions.

Innovative Discharge Process for Families with Pediatric Short Bowel Syndrome: A Prospective Nonrandomized Trial.

BACKGROUND: Home parenteral nutrition (HPN) is a life-sustaining therapy for short bowel syndrome (SBS) and other severe digestive diseases, but complications are common. We evaluated a predischarge HPN hands-on training course to reduce complications in children with SBS, including hospital readmissions. METHODS: We conducted a prospective, nonrandomized controlled research study between April 1, 2014, and April 30, 2017. Eligible participants were children aged <18 years old with SBS and anticipated HPN dependence duration ≥6 months. Excluded participants had a previous history of discharge with a central venous catheter (CVC), HPN, or intravenous fluids or strictly palliative goals of care. An intervention group practiced hands-on HPN within the hospital room for 24 hours using infusion equipment. The groups received standard teaching (CVC care, home infusion pump operation, HPN preparation and administration). RESULTS: Nine children were assigned to the intervention group and 12 served as controls. The median age was 8.4 months, and length of stay (LOS) was 82 days. All participants experienced ≥1 event, with a total of 47 issues related to HPN. There were no significant associations between group assignment and 30-day postdischarge events. Each additional week of LOS was associated with 11% increase in the odds of an emergency department visit (OR 1.11; 95% CI, 1.01-1.26) and 16% increase in the odds of readmission (OR 1.16; 95% CI, 1.04-1.37). CONCLUSIONS: Postdischarge events remained widespread despite HPN bedside interventions offered by this pilot intervention. With refinement of HPN discharge processes, quality benchmarks are needed.

Spectroscopic studies on the darkening of lead white.

Lead white is an historically important paint used by artists since antiquity. The darkening of lead white has been well documented in works of art such as paintings. In this paper, mid-infrared (MIR) and visible spectroscopy were used to examine spectral changes accompanying the darkening of lead white paint as a result of exposure to H2S(g). Laboratory-prepared paint and a commercial lead white paint were used to observe the darkening reaction over time. Structural changes to the pigment, 2PbCO3.Pb(OH)2, in lead white were readily detected using MIR by applying a thin film on a KBr pellet. Spectral changes at 3541 (O-H stretch), 1400 (C-O), and 680 cm-1 (C-O) were the most significant over time as the paint darkened. Visible spectra were also collected to provide a semi-quantitative measure of color change with structural changes observed by MIR. Experiments in the visible region were also conducted to compare the spectral response as % reflected and % transmitted light as lead white darkened. The effect of different binding agents (egg tempera, linseed oil, water, and gum Arabic) on the rate of darkening of lead white was also examined. Other sulfur-containing pigments such as orpiment and realgar were also tested for their ability to darken lead white. By applying paint as a thin film inside a sealed cuvette, darkening of lead white was observed in the visible spectra (800 nm) when either powdered orpiment or realgar was in placed in the cuvette for 24 h.
