Caregiver Decision-making in Pediatric Intestinal Failure: A Qualitative Study Focused on Iron Deficiency Anemia.

BACKGROUND: Caregivers of children with intestinal failure (IF) face difficult decisions without a clear best alternative. Providers assist in decision-making but often lack knowledge of caregiver perspectives. Using decision-making around anemia treatment as a focal point, we explored how caregivers of children with IF prefer to make decisions. Our goal was to offer insight to guide providers as they assist in decision-making. METHODS: We conducted 12 half-hour semistructured interviews with parents of children with IF. Interview questions addressed general decision-making and specifics of iron supplementation, including key factors and stakeholders in decision-making. Interviews were transcribed verbatim. Two investigators coded the transcripts and inductively derived themes. RESULTS: Four themes were identified regarding decision-making. They involved the search for reliable, accurate, and positive information; the role of caretakers on the medical team; the relationships between caretakers and the medical team; and effective communication. Themes around anemia treatment included: identification of anemia by bloodwork; proactive supplementation; individualized regimens; prioritizing safety and convenience. CONCLUSIONS: Understanding caregiver perspectives regarding anemia treatment in pediatric IF identifies opportunities for systematic quality improvement.

Cost-effectiveness of teduglutide in pediatric patients with short bowel syndrome: Markov modeling using traditional cost-effectiveness criteria.

BACKGROUND: Teduglutide use in pediatric patients with short bowel syndrome can aid in the achievement of enteral autonomy, but with a price of >$400,000 per y. OBJECTIVE: The current study evaluated the cost-effectiveness of using teduglutide in conjunction with offering intestinal transplantation in US pediatric patients with short bowel syndrome. DESIGN: A Markov model was used to evaluate the costs (in US dollars) and effectiveness [in quality-adjusted life years (QALYs)] of using teduglutide compared with offering intestinal transplantation. Parameters were estimated from published data where available. The primary effect modeled was the probability of weaning from parenteral nutrition while on teduglutide. Sensitivity analyses were performed on all model parameters. RESULTS: Compared with offering only intestinal transplantation, adding teduglutide cost ${\$}$124,353/QALY gained. Reducing the cost of the medication by 16% allowed the cost to reach the typical benchmark of ${\$}$100,000/QALY gained. Probabilistic sensitivity analysis favored transplantation without offering teduglutide in 68% of iterations at a ${\$}$100,000/QALY threshold. Never using teduglutide created an opportunity cost of over ${\$}$100,000 per patient. CONCLUSIONS: At its current price, teduglutide does not provide a cost-effective addition to transplantation in the treatment of pediatric short bowel syndrome. Further work should look to identify cost-reducing strategies, including alternative dosing regimens.

Predictors of Enteral Autonomy in Children with Intestinal Failure: A Multicenter Cohort Study.

OBJECTIVES: In a large cohort of children with intestinal failure (IF), we sought to determine the cumulative incidence of achieving enteral autonomy and identify patient and institutional characteristics associated with enteral autonomy. STUDY DESIGN: A multicenter, retrospective cohort analysis from the Pediatric Intestinal Failure Consortium was performed. IF was defined as severe congenital or acquired gastrointestinal diseases during infancy with dependence on parenteral nutrition (PN) >60 days. Enteral autonomy was defined as PN discontinuation >3 months. RESULTS: A total of 272 infants were followed for a median (IQR) of 33.5 (16.2-51.5) months. Enteral autonomy was achieved in 118 (43%); 36 (13%) remained PN dependent and 118 (43%) patients died or underwent transplantation. Multivariable analysis identified necrotizing enterocolitis (NEC; OR 2.42, 95% CI 1.33-4.47), care at an IF site without an associated intestinal transplantation program (OR 2.73, 95% CI 1.56-4.78), and an intact ileocecal valve (OR 2.80, 95% CI 1.63-4.83) as independent risk factors for enteral autonomy. A second model (n = 144) that included only patients with intraoperatively measured residual small bowel length found NEC (OR 3.44, 95% CI 1.36-8.71), care at a nonintestinal transplantation center (OR 6.56, 95% CI 2.53-16.98), and residual small bowel length (OR 1.04 cm, 95% CI 1.02-1.06 cm) to be independently associated with enteral autonomy. CONCLUSIONS: A substantial proportion of infants with IF can achieve enteral autonomy. Underlying NEC, preserved ileocecal valve, and longer bowel length are associated with achieving enteral autonomy. It is likely that variations in institutional practices and referral patterns also affect outcomes in children with IF.

Natural history of pediatric intestinal failure: initial report from the Pediatric Intestinal Failure Consortium.

OBJECTIVE: To characterize the natural history of intestinal failure (IF) among 14 pediatric centers during the intestinal transplantation era. STUDY DESIGN: The Pediatric Intestinal Failure Consortium performed a retrospective analysis of clinical and outcome data for a multicenter cohort of infants with IF. Entry criteria included infants <12 months receiving parenteral nutrition (PN) for >60 continuous days. Enteral autonomy was defined as discontinuation of PN for >3 consecutive months. Values are presented as median (25th, 75th percentiles) or as number (%). RESULTS: 272 infants with a gestational age of 34 weeks (30, 36) and birth weight of 2.1 kg (1.2, 2.7) were followed for 25.7 months (11.2, 40.9). Residual small bowel length in 144 patients was 41 cm (25.0, 65.5). Diagnoses were necrotizing enterocolitis (71, 26%), gastroschisis (44, 16%), atresia (27, 10%), volvulus (24, 9%), combinations of these diagnoses (46, 17%), aganglionosis (11, 4%), and other single or multiple diagnoses (48, 18%). Prescribed medications included oral antibiotics (207, 76%), H2 blockers (187, 69%), and proton pump inhibitors (156, 57%). Enteral feeding approaches varied among centers; 19% of the cohort received human milk. The cohort experienced 8.9 new catheter-related blood stream infections per 1000 catheter days. The cumulative incidences for enteral autonomy, death, and intestinal transplantation were 47%, 27%, and 26%, respectively. Enteral autonomy continued into the fifth year after study entry. CONCLUSIONS: Children with IF endure significant mortality and morbidity. Enteral autonomy may require years to achieve. Improved medical, nutritional, and surgical management may reduce time on PN, mortality, and need for transplantation.
