Prioritising allocation of donor human breast milk amongst very low birthweight infants in middle-income countries.

The use of donor human breast milk instead of formula reduces the risk of necrotising enterocolitis in preterm infants when their mother's own milk is insufficient. Use of donor milk is limited by the cost of establishing a milk bank and a lack of donors, but the optimal rationing of limited donor milk is unclear. This paper uses an economic model to explore how a limited donor milk supply should be allocated across very low birthweight infants in South Africa considering 2 outcomes: maximising lives saved and minimising costs. We developed a probabilistic cohort Markov decision model with 10,000 infants across 4 birthweight groups. We evaluated allocation scenarios in which infants in each group could be exclusively formula-fed or fed donor milk for 14 or 28 days and thereafter formula until death or discharge. Prioritising infants in the lowest birthweight groups would save the most lives, whereas prioritising infants in the highest birthweight groups would result in the highest cost savings. All allocation scenarios would be considered very cost-effective in South Africa compared to the use of formula; the "worst case" was $619 per Disability Adjusted Life Year averted. There is a compelling argument to increase the supply of donor milk in middle-income countries. Our analysis could be extended by taking a longer term perspective, using data from more than one country and exploring the use of donor milk as an adjunct to mother's own milk, rather than a pure substitute for it.

Impact of Optimized Breastfeeding on the Costs of Necrotizing Enterocolitis in Extremely Low Birthweight Infants.

OBJECTIVE: To estimate risk of necrotizing enterocolitis (NEC) for extremely low birth weight (ELBW) infants as a function of preterm formula (PF) and maternal milk intake and calculate the impact of suboptimal feeding on the incidence and costs of NEC. STUDY DESIGN: We used aORs derived from the Glutamine Trial to perform Monte Carlo simulation of a cohort of ELBW infants under current suboptimal feeding practices, compared with a theoretical cohort in which 90% of infants received at least 98% human milk. RESULTS: NEC incidence among infants receiving ≥98% human milk was 1.3%; 11.1% among infants fed only PF; and 8.2% among infants fed a mixed diet (P = .002). In adjusted models, compared with infants fed predominantly human milk, we found an increased risk of NEC associated with exclusive PF (aOR = 12.1, 95% CI 1.5, 94.2), or a mixed diet (aOR 8.7, 95% CI 1.2-65.2). In Monte Carlo simulation, current feeding of ELBW infants was associated with 928 excess NEC cases and 121 excess deaths annually, compared with a model in which 90% of infants received ≥98% human milk. These models estimated an annual cost of suboptimal feeding of ELBW infants of $27.1 million (CI $24 million, $30.4 million) in direct medical costs, $563 655 (CI $476 191, $599 069) in indirect nonmedical costs, and $1.5 billion (CI $1.3 billion, $1.6 billion) in cost attributable to premature death. CONCLUSIONS: Among ELBW infants, not being fed predominantly human milk is associated with an increased risk of NEC. Efforts to support milk production by mothers of ELBW infants may prevent infant deaths and reduce costs.

The entwined circles of quality improvement & advocacy.

Health policy and quality improvement initiatives exist symbiotically. Quality projects can be spurred by policy decisions, such as the creation of financial incentives for high-value care. Then, advocacy can streamline high-value care, offering opportunities for quality improvement scholars to create projects consistent with evidenced-based care. Thirdly, as pediatrics and neonatology reconcile with value-based payment structures, successful quality initiatives may serve as demonstration projects, illustrating to policy-makers how best to allocate and incentivize resources that optimize newborn health. And finally, quality improvement (QI) can provide an essential link between broad reaching advocacy principles and boots-on-the-ground local or regional efforts to implement good ideas in ways that work practically in particular environments. In this paper, we provide examples of how national legislation elevated the importance of QI, by penalizing hospitals for low quality care. Using Medicaid coverage of pasteurized human donor milk as an example, we discuss how advocacy improved cost-effectiveness of treatments used as tools for quality projects related to reduction of necrotizing enterocolitis and improved growth. We discuss how the future of QI work will assist in informing the agenda as neonatology transitions to value-based care. Finally, we consider how important local and regional QI work is in bringing good ideas to the bedside and the community.

Long term healthcare costs of infants who survived neonatal necrotizing enterocolitis: a retrospective longitudinal study among infants enrolled in Texas Medicaid.

BACKGROUND: Infants who survive advanced necrotizing enterocolitis (NEC) at the time of birth are at increased risk of having poor long term physiological and neurodevelopmental growth. The economic implications of the long term morbidity in these children have not been studied to date. This paper compares the long term healthcare costs beyond the initial hospitalization period incurred by medical and surgical NEC survivors with that of matched controls without a diagnosis of NEC during birth hospitalization. METHODS: The longitudinal healthcare utilization claim files of infants born between January 2002 and December 2003 and enrolled in the Texas Medicaid fee-for-service program were used for this research. Propensity scoring was used to match infants diagnosed with NEC during birth hospitalization to infants without a diagnosis of NEC on the basis of gender, race, prematurity, extremely low birth weight status and presence of any major birth defects. The Medicaid paid all-inclusive healthcare costs for the period from 6 months to 3 years of age among children in the medical NEC, surgical NEC and matched control groups were evaluated descriptively, and in a generalized linear regression framework in order to model the impact of NEC over time and by birth weight. RESULTS: Two hundred fifty NEC survivors (73 with surgical NEC) and 2,909 matched controls were available for follow-up. Medical NEC infants incurred significantly higher healthcare costs than matched controls between 6-12 months of age (mean incremental cost = US$ 5,112 per infant). No significant difference in healthcare costs between medical NEC infants and matched controls was seen after 12 months. Surgical NEC survivors incurred healthcare costs that were consistently higher than that of matched controls through 36 months of age. The mean incremental healthcare costs of surgical NEC infants compared to matched controls between 6-12, 12-24 and 24-36 months of age were US$ 18,274, 14,067 (p < 0.01) and 8,501 (p = 0.06) per infant per six month period, respectively. These incremental costs were found to vary between sub-groups of infants born with birth weight < 1,000g versus ≥ 1,000g (p < 0.05). CONCLUSIONS: The all-inclusive healthcare costs of surgical NEC survivors continued to be substantially higher than that of matched controls through the early childhood development period. These results can have important treatment and policy implications. Further research in this topic is needed.

A case study on the economic impact of optimal breastfeeding.

To develop a framework, using Louisiana as a case study, for estimating the potential cost savings to individual states if families were able to meet current recommendations for breastfeeding. Using cost-analyses methods, cost savings, as well as, case and death reductions of infant illnesses and deaths on four selected infant diseases (respiratory tract infections, gastroenteritis, necrotizing enterocolitis, and Sudden Infant Death Syndrome) were calculated utilizing the most recent data of breastfeeding and low/very low birth weight rates in Louisiana. To estimate the incidence of a disease in exclusive breastfed infants and formula fed infants respectively, we used the following formula: x = s/br + 1 - b. Here "x" is the incidence rate of one disease in formula fed infants, "s" is the overall incidence of the disease, "b" is current breastfeeding rate and "r" is the odds ratios in favor of breastfeeding. A total of $216,103,368 could be saved and 18 infant deaths prevented, by these four conditions alone, if 90% of newborns in Louisiana were exclusive breastfed for the first 6 months of life ($186,371,125 in savings and 16 infant deaths prevented with 80% compliance). Increased rates of breastfeeding to the level of Healthy People 2020 goals and beyond would yield significant cost savings to Louisiana. Other US states can use the presented framework to demonstrate cost savings associated with breastfeeding promotion and support interventions in their respective states.

Can we cut the incidence of necrotizing enterocolitis in half--today?

Necrotizing enterocolitis (NEC) is a common gastrointestinal emergency of neonates. Population studies estimate the incidence of NEC at between 0.3 and 2.4 per 1000 live births in the United States, with a predominance of cases among preterm neonates born at the earliest gestational ages. The disease burden of NEC includes an overall disease-specific mortality rate of 15-20%, with yet higher rates in those of earliest gestations. The NEC burden also includes an increase in hospital costs approximating $100,000/case, as well as severe late sequellae including parenteral nutrition-associated liver disease and short bowel syndrome. Differentiating NEC from other forms of acquired neonatal intestinal disease is critical to assessing the success of NEC prevention strategies. Promising new prevention strategies are now being tested; one such is prophylactic heparin-binding epidermal growth factor-like growth factor (HB-EGF) administration. However, two prevention strategies have already been shown in meta-analyses to reduce the incidence of NEC, but we speculate that these are not being fully utilized. They are; 1) implementing a written set of feeding guidelines (also called standardized feeding regimens) for newborn intensive care unit (NICU) patients, and 2) implementing programs to increase the availability of human milk for patients at risk of developing NEC.

The economic benefits of increasing breastfeeding rates in Spain.

BACKGROUND: Interventions aimed at promoting breastfeeding rates are among the most effective possible health policies available, with an estimated return of US$35 per dollar invested. Indeed, some authors found that a 10% increase in exclusive breastfeeding rates in the first two years of life led to a reduction in treatment costs of US$312 million in the US, US$7.8 million in the UK, US$30 million in China, and US$1.8 million in Brazil. Among high-income countries, Spain stands out for its low breastfeeding rate. METHODS: We calculated the savings that the Spanish National Health System would have benefited from had breastfeeding rates been higher in Spain, both from the time of hospital discharge and at 6 months postpartum. We followed the methods used in similar studies carried out in the US, Italy, Australia, the Netherlands, and the UK, to conservatively estimate these potential savings by considering only the lower thresholds in all our estimates. Here we approximated the benefits of having increased exclusive breastfeeding rates based on the lower incidence of infantile pathologies among exclusively breastfed infants. Robust evidence indicates that among breastfed infants there is a lower prevalence of otitis media, gastroenteritis, respiratory infections, and necrotising enterocolitis. We obtained the estimated monetary cost of these diseases by combining their prevalences with data about their economic costs for diagnosis-related groups. RESULTS: The estimated effects we calculated imply that the Spanish National Health System could have saved more than €5.6 million for every percentage point increase in exclusive breastfeeding rates in Spain during 2014. CONCLUSIONS: Breastfeeding is essential both for the health of mothers and the health and development of newborns but is rarely considered as an economic issue and remains economically invisible. In addition to the improved wellbeing of mothers and their infants, breastfeeding can positively impact society as a whole and should therefore be better defined in public policies. Thus, strategies aimed at increasing exclusive breastfeeding rates would likely contribute to lowering the fiscal burden of the Spanish National Health System. Moreover, the magnitude of these potential benefits suggests that such policies would likely be socially cost-effective.

The cost of necrotizing enterocolitis in premature infants.

Necrotizing enterocolitis (NEC), a common morbidity of prematurity, affects 5-10% of premature infants with a birthweight <1500 g. The added cost remains unclear. Multiple studies report the cost of care for an infant with NEC as higher than that of well premature infants, but these studies are fraught with limitations. Surgical intervention and type of surgery appear to impact overall costs. Health care resource utilization extends beyond the birth hospitalization, particularly in those infants requiring surgery, and persists to at least three years of age. This narrative review of the literature reveals a paucity of studies and significant methodological deficiencies in most included studies. Further studies of the cost of NEC need to address the issues of significant confounding in this complex population.

Cost and Cost-Effectiveness of Donor Human Milk to Prevent Necrotizing Enterocolitis: Systematic Review.

BACKGROUND: Necrotizing enterocolitis (NEC) is a costly gastrointestinal disorder that mainly affects preterm and low-birth-weight infants and can lead to considerable morbidity and mortality. Mother's own milk is protective against NEC but is not always available. In such cases, donor human milk has also been shown to be protective (although to a lesser extent) compared with formula milk, but it is more expensive. This systematic review aimed at evaluating the cost of donor milk, the cost of treating NEC, and the cost-effectiveness of exclusive donor milk versus formula milk feeding to reduce the short-term health and treatment costs of NEC. MATERIALS AND METHODS: We systematically searched five relevant databases to find studies with verifiable costs or charges of donor milk and/or treatment of NEC and any economic evaluations comparing exclusive donor milk with exclusive formula milk feeding. All search results were double screened. RESULTS: Seven studies with verifiable donor milk costs and 17 with verifiable NEC treatment costs were included. The types of cost or charge included varied considerably across studies, so quantitative synthesis was not attempted. Estimates of the incremental length of stay associated with NEC were ∼18 days for medical NEC and 50 days for surgical NEC. Two studies claimed to report economic evaluations but did not do so in practice. CONCLUSIONS: It is likely that donor milk provides short-term cost savings by reducing the incidence of NEC. Future studies should provide more details on cost components included and a full economic evaluation, including long-term outcomes, should be undertaken.

Current Knowledge of Necrotizing Enterocolitis in Preterm Infants and the Impact of Different Types of Enteral Nutrition Products.

Preterm infants are extremely vulnerable to a range of morbidities and mortality. Underdeveloped cardiac, respiratory, gastrointestinal, and immune systems in the preterm period increase the risk of necrotizing enterocolitis (NEC), a serious disease of the gut. NEC affects 5-12% of very-low birth-weight infants, leads to surgery in 20-40% of cases, and is fatal in 25-50% of cases. There are multiple factors that may contribute to NEC, but the exact cause is not yet fully understood. Severe cases can result in intestinal resection or death, and the health care costs average >$300,000/infant when surgical management is required. Different types of nutrition may affect the onset or progression of NEC. Several studies have indicated that bovine milk-based infant formulas lead to a higher incidence of NEC in preterm infants than does human milk (HM). However, it is not clear why HM is linked to a lower incidence of NEC or why some infants fed an exclusively HM diet still develop NEC. An area that has not been thoroughly explored is the use of semielemental or elemental formulas. These specialty formulas are easy to digest and absorb in the gut and may be an effective nutritional intervention for reducing the risk of NEC. This review summarizes what is known about the factors that contribute to the onset and progression of NEC, discusses its health care cost implications, and explores the impact that different formulas and HM have on this disease.

Decreased cost and improved feeding tolerance in VLBW infants fed an exclusive human milk diet.

OBJECTIVE: Human milk is the best form of nutrition for preterm infants and has been associated with a lower incidence of necrotizing enterocolitis (NEC). Infants that develop NEC have a higher incidence of feeding intolerance and longer hospitalizations. The combination of a donor milk bank and donor milk-derived fortifier has changed feeding practices in neonatal intensive care units (NICU). The purpose of this study is to assess the benefits and cost of an exclusive human milk (EHM) diet in very low birth weight (VLBW) infants in a community level III NICU. STUDY DESIGN: This is a retrospective study including preterm infants ⩽28 weeks and/or VLBW (⩽1500 g) who were enrolled from March 2009 until March 2014. Infants were grouped as follows: group H (entirely human milk based, born March 2012 to 2014), group B (bovine-based fortifier and maternal milk, born March 2009 to 2012), group M (mixed combination of maternal milk, bovine-based fortifier and formula, born March 2009 to 2012) and group F (formula fed infants, born March 2009 to 2012). Baseline characteristics among the four groups were similar. RESULT: The study included 293 infants between gestational ages 23 to 34 weeks and birth weights between 490 and 1700 g. Feeding intolerance occurred less often (P<0.0001), number of days to full feeds was lower (P<0.001), incidence of NEC was lower (P<0.011), and total hospitalization costs were lower by up to $106,968 per infant (P<0.004) in those fed an EHM diet compared with the other groups. Average weight gain per day was similar among the four groups (18.5 to 20.6 g per day). CONCLUSIONS: Implementing an EHM diet in our VLBW infants has led to a significant decrease in the incidence of NEC. Other benefits of this diet include: decreased feeding intolerance, shorter time to full feeds, shorter length of stay, and lower hospital and physician charges for extremely premature and VLBW infants.

Outcomes and costs of surgical treatments of necrotizing enterocolitis.

BACKGROUND AND OBJECTIVES: Despite previous studies demonstrating no difference in mortality or morbidity, the various surgical approaches for necrotizing enterocolitis (NEC) in infants have not been evaluated economically. Our goal was to compare total in-hospital cost and mortality by using propensity score-matched infants treated with peritoneal drainage alone, peritoneal drainage followed by laparotomy, or laparotomy alone for surgical NEC. METHODS: Utilizing the California OSHPD Linked Birth File Dataset, 1375 infants with surgical NEC between 1999 and 2007 were retrospectively propensity score matched according to intervention type. Total in-hospital costs were converted from longitudinal patient charges. A multivariate mixed effects model compared adjusted costs and mortality between groups. RESULTS: Successful propensity score matching was performed with 699 infants (peritoneal drainage, n = 101; peritoneal drainage followed by laparotomy, n = 172; and laparotomy, n = 426). Average adjusted cost for peritoneal drainage followed by laparotomy was $398,173 (95% confidence interval [CI]: 287,784-550,907), which was more than for peritoneal drainage ($276,076 [95% CI: 196,238-388,394]; P = .004) and similar to laparotomy ($341,911 [95% CI: 251,304-465,186]; P = .08). Adjusted mortality was highest after peritoneal drainage (56% [95% CI: 34-75]) versus peritoneal drainage followed by laparotomy (35% [95% CI: 19-56]; P = .01) and laparotomy (29% [95% CI: 19-56]; P < .001). Mortality for peritoneal drainage was similar to laparotomy. CONCLUSIONS: Propensity score-matched analysis of surgical NEC treatment found that peritoneal drainage followed by laparotomy was associated with decreased mortality compared with peritoneal drainage alone but at significantly increased costs.

Cost savings of human milk as a strategy to reduce the incidence of necrotizing enterocolitis in very low birth weight infants.

BACKGROUND: Necrotizing enterocolitis (NEC) is a costly morbidity in very low birth weight (VLBW; <1,500 g birth weight) infants that increases hospital length of stay and requires expensive treatments. OBJECTIVES: To evaluate the cost of NEC as a function of dose and exposure period of human milk (HM) feedings received by VLBW infants during the neonatal intensive care unit (NICU) hospitalization and determine the drivers of differences in NICU hospitalization costs for infants with and without NEC. METHODS: This study included 291 VLBW infants enrolled in an NIH-funded prospective observational cohort study between February 2008 and July 2012. We examined the incidence of NEC, NICU hospitalization cost, and cost of individual resources used during the NICU hospitalization. RESULTS: Twenty-nine (10.0%) infants developed NEC. The average total NICU hospitalization cost (in 2012 USD) was USD 180,163 for infants with NEC and USD 134,494 for infants without NEC (p = 0.024). NEC was associated with a marginal increase in costs of USD 43,818, after controlling for demographic characteristics, risk of NEC, and average daily dose of HM during days 1-14 (p < 0.001). Each additional ml/kg/day of HM during days 1-14 decreased non-NEC-related NICU costs by USD 534 (p < 0.001). CONCLUSIONS: Avoidance of formula and use of exclusive HM feedings during the first 14 days of life is an effective strategy to reduce the risk of NEC and resulting NICU costs in VLBW infants. Hospitals investing in initiatives to feed exclusive HM during the first 14 days of life could substantially reduce NEC-related NICU hospitalization costs.

The costs of inadequate breastfeeding of infants in Mexico.

BACKGROUND: Breastfeeding is vital for child survival, health, and development. Mexico has very low rates of breastfeeding and experienced a severe decrease in the prevalence of exclusive breastfeeding from 21% in 2006 to 14% in 2012. OBJECTIVE: The objective of the article was to estimate the pediatric costs of inadequate breastfeeding in Mexico associated with the following acute health conditions: respiratory infections, otitis media, gastroenteritis, necrotizing enterocolitis (NEC), and sudden infant death syndrome (SIDS). DESIGN: The authors estimated the economic costs of inadequate breastfeeding as follows: the sum of direct health care costs for diseases whose risk increases when infants are non-exclusively breastfed <6 mo or are not breastfed from ages 6 to <11 mo, lost future earnings due to premature infant death, and the costs of purchasing infant formula. Incidence cases were retrieved from national surveillance systems, except for NEC and SIDS, which were estimated from the literature. A sensitivity analysis was carried out to provide a range of costs based on different assumptions of the number of incident cases of all infant health outcomes examined. The model applied to the cohort of 1-y-old children born in 2012. RESULTS: The total annual costs of inadequate breastfeeding in Mexico for the studied cohort ranged from $745.6 million to $2416.5 million, where the costs of infant formula accounted for 11-38% of total costs. A range of 1.1-3.8 million reported cases of disease and from 933 to 5796 infant deaths per year for the diseases under study are attributed to inadequate infant breastfeeding practices; altogether these represent nearly 27% of the absolute number of episodes of such diseases. CONCLUSIONS: This study provides costs of inadequate breastfeeding that had not been quantified in Mexico. The costs presented in this article provide the minimum amount that the country should invest to achieve better breastfeeding practices.

The cost-effectiveness of using banked donor milk in the neonatal intensive care unit: prevention of necrotizing enterocolitis.

Necrotizing enterocolitis (NEC) adds significantly to the cost of care for premature infants and to negative long-term and short-term outcomes for these infants. It is thus in the best interest of the health care system to prevent the occurrence of NEC through feeding protocols that foster NEC prevention (i.e., use of breast milk in the neonatal intensive care unit). Banked donor milk has been shown to be as effective in preventing NEC as mother's milk. Three models of cost analysis are presented to show savings that could accrue to a health care system or individual family if banked donor milk were provided as first feedings when mother's milk is not available. The cost of using banked donor milk to feed premature infants is inconsequential when compared to the savings from NEC prevention.

Health, nutrition, and cost outcomes of human milk feedings for very low birthweight infants.

This symposium examined the impact of human milk (HM) from the infant's own mother on health, nutrition, and cost outcomes in very low birthweight (VLBW; <1500 g birthweight) infants. The 4 symposium speakers presented original research and summarized existing evidence about these primary outcomes. The conclusions from the symposium suggest that: 1) HM feedings for VLBW infants in the neonatal intensive care unit (NICU) reduce the risks and the associated costs of late onset sepsis and necrotizing enterocolitis (NEC); 2) the gut microbiota of the VLBW infant is influenced by multiple factors, some of which are modifiable, and that the milk microbiota affects the developing gut microbiota in a positive manner; 3) the clinical realties of feeding HM in the NICU that compromise safety and efficacy of HM can be addressed with evidence-based clinical practices; and 4) piglets can serve as a model for the premature infant to assess the impact of HM and formula additives on intestinal development.

Late vs early ostomy closure for necrotizing enterocolitis: analysis of adhesion formation, resource consumption, and costs.

BACKGROUND: Surgeons prefer to close ostomies at least 6 weeks after the primary operation because of the anticipated postoperative abdominal adhesions. Limited data support this habit. Our aim was to evaluate adhesion formation-together with an analysis of resource consumption and costs-in patients with necrotizing enterocolitis who underwent early closure (EC), compared with a group of patients who underwent late closure (LC). METHODS: Chart reviews and cost analyses were performed on all patients with necrotizing enterocolitis undergoing ostomy closure from 1997 to 2009. Operative reports were independently scored for adhesions by 2 surgeons. RESULTS: Thirteen patients underwent EC (median, 39 days; range, 32-40), whereas 62 patients underwent LC (median, 94 days; range, 54-150). Adhesion formation in the EC group (10/13 patients, or 77%) was not significantly different (P = 1.000) from the LC group (47/59 patients, or 80%). No differences were found in the costs of hospital stay, surgical interventions, and outpatient clinic visits. CONCLUSIONS: Ostomy closure within 6 weeks of the initial procedure was not associated with more adhesions or with changes in direct medical costs. Therefore, after stabilization of the patient, ostomy closure can be considered within 6 weeks during the same admission as the initial laparotomy.

Costs of necrotizing enterocolitis and cost-effectiveness of exclusively human milk-based products in feeding extremely premature infants.

OBJECTIVE: This study evaluated the cost-effectiveness of a 100% human milk-based diet composed of mother's milk fortified with a donor human milk-based human milk fortifier (HMF) versus mother's milk fortified with bovine milk-based HMF to initiate enteral nutrition among extremely premature infants in the neonatal intensive care unit (NICU). METHODS: A net expected costs calculator was developed to compare the total NICU costs among extremely premature infants who were fed either a bovine milk-based HMF-fortified diet or a 100% human milk-based diet, based on the previously observed risks of overall necrotizing enterocolitis (NEC) and surgical NEC in a randomized controlled study that compared outcomes of these two feeding strategies among 207 very low birth weight infants. The average NICU costs for an extremely premature infant without NEC and the incremental costs due to medical and surgical NEC were derived from a separate analysis of hospital discharges in the state of California in 2007. The sensitivity of cost-effectiveness results to the risks and costs of NEC and to prices of milk supplements was studied. RESULTS: The adjusted incremental costs of medical NEC and surgical NEC over and above the average costs incurred for extremely premature infants without NEC, in 2011 US$, were $74,004 (95% confidence interval, $47,051-$100,957) and $198,040 (95% confidence interval, $159,261-$236,819) per infant, respectively. Extremely premature infants fed with 100% human-milk based products had lower expected NICU length of stay and total expected costs of hospitalization, resulting in net direct savings of 3.9 NICU days and $8,167.17 (95% confidence interval, $4,405-$11,930) per extremely premature infant (p < 0.0001). Costs savings from the donor HMF strategy were sensitive to price and quantity of donor HMF, percentage reduction in risk of overall NEC and surgical NEC achieved, and incremental costs of surgical NEC. CONCLUSIONS: Compared with feeding extremely premature infants with mother's milk fortified with bovine milk-based supplements, a 100% human milk-based diet that includes mother's milk fortified with donor human milk-based HMF may result in potential net savings on medical care resources by preventing NEC.

Necrotizing enterocolitis requiring surgery: outcomes by intestinal location of disease in 4371 infants.

OBJECTIVE: The objective of this study was to determine whether the outcomes of infants with surgically managed necrotizing enterocolitis (NEC) differ according to whether the location of NEC is in the small bowel, large bowel, or both. STUDY DESIGN: A retrospective analysis was performed using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample and Kids' Inpatient Database. A total of 5374 infants identified as having undergone surgical management of NEC were stratified by location of bowel affected as small bowel (SB) only, large bowel (LB) only, or both small and large bowel (SB&LB). The type of surgical operation performed was used as a proxy for the location of bowel affected. RESULTS: Of the 5374 infants with a diagnosis of NEC, 4371 had an operation that allowed for stratification by location. The LB group (n = 963) fared the best in all outcomes. The SB group (n = 2126) had the longest length of stay and highest total hospital charges, and mortality was comparable with that of the SB&LB group (n = 1282). CONCLUSIONS: Mortality, length of stay, and total hospital charges varied according to location of bowel affected by NEC.
