Ethics of emerging technologies and their transition to accepted practice: intestinal transplant for short bowel syndrome

Parental counseling becomes complex when considering the use of emerging technologies, especially if it is unclear whether the level of evidence is sufficient to transform the proposed therapy into accepted practice. This paper addresses ethical issues underlying medical decision-making and counseling in the setting of emerging treatments, when long-term outcomes are still in the process of being fully validated. We argue that the ethical transition of emerging technologies, ideally from ethically impermissible to permissible, to obligatory, depends primarily on two factors: outcome data (or prognosis) and treatment feasibility. To illustrate these points, we will use intestinal transplant for short bowel syndrome (SBS) as a specific example. After reviewing the data, this paper will identify the ethical justifications for both comfort care only and intestinal transplant in patients with ultra SBS, and argue that both are ethically permissible, but neither is obligatory. The approach outlined will not only be valuable as ultra SBS outcomes data continue to change, but will also be applicable to other novel therapies as they emerge in perinatal medicine.

Bloodstream infections in very low birth weight infants with intestinal failure

OBJECTIVE

To examine pathogens and other characteristics associated with late-onset bloodstream infections (BSIs) in infants with intestinal failure (IF) as a consequence of necrotizing enterocolitis (NEC).

STUDY DESIGN

Infants weighing 401-1500 g at birth who survived for >72 hours and received care at Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network centers were studied. The frequency of culture-positive BSI and pathogens were compared in infants with medically managed NEC, NEC managed surgically without IF, and surgical IF. Among infants with IF, the duration of parenteral nutrition (PN) and other outcomes were evaluated.

RESULTS

A total of 932 infants were studied (IF, n = 78; surgical NEC without IF, n = 452; medical NEC, n = 402). The proportion with BSI after diagnosis of NEC was higher in the infants with IF than in those with surgical NEC (P = .007) or medical NEC (P < .001). Gram-positive pathogens were most frequent. Among infants with IF, an increased number of infections was associated with longer hospitalization and duration of PN (median stay: 172 for those with 0 infections, 188 days for those with 1 infection, and 260 days for those with ≥2 infections [P = .06]; median duration of PN: 90, 112, and 115 days, respectively [P = .003]) and decreased achievement of full feeds during hospitalization (87%, 67%, and 50%, respectively; P = .03).

CONCLUSION

Recurrent BSIs are common in very low birth weight infants with IF. Gram-positive bacteria were the most commonly identified organisms in these infants.
