Impact of Neonatology to Healthcare Burden• Between 7% (CAN) to 12% (US) of live births are preterm (less than 37

weeks gestation)• NICU patients (preterm and sick newborns) represent a

disproportionate share of hospital costs• Lifelong impact to healthcare burden and costs enormous• In the US, NICU is a top generator of financial revenue to hospitals

Goal of Feeding Preterm Infants

Provide nutrients to approximate the rate of growth and composition of weight gain for a normal fetus of the same post-conceptional age and to maintain normal concentrations of blood and tissue nutrients.

threatening gastrointestinal emergency in the newborn period

• NEC is marked by intense inflammation and acute intestinal necrosis

• Most common sites include terminal ileum, cecum and ascending colon

• Can lead to need for long-term PN use and later bowel transplantation

• Neurodevelopmental impairment!

Strategies to prevent NEC

• Prevent preterm birth• Standardized feeding

protocol• Exclusive human milk

feeding• Antibiotic stewardship• Reduce anti-acid meds• Probiotics

• Blood transfusions• Patent ductus arteriosus• Congenital heart disease• Prebiotics• Minimize osmolality

Standardized Feeding ProtocolHaving a feeding protocol is associated with reduced NEC rates

Patole, Arch Dis Child Fetal Neonatal Ed. 2005;90(2):F147-151.

Key Elements of a Great Feeding Protocol• Established consensus from

medical faculty• Visible, nurse-driven advancement• Linear advancement• Trophic feeding for extremely

preterm infants• Incorporate timing of fortification

and vitamins

Page 25: Oct 24   CAPHC Lunch Symposium - Sponsored by Prolacta - Dr. Jae Kim

10% of very preterm babies developed NEC

30-50% NEED SURGERY

25-50% DIE!

Human milk can reduce NEC (medical and surgical) by at least 50%

Most very preterm infants are fed formula!!

Lactation support• Ideally mothers should initiate

pumping or breastfeeding within 2h after vaginal delivery and 4h after cesarean section

• Peak lactation volumes may be influenced by very early pumping/expressing milk within the first hour of life

Containing Health Care Costs• What motivates reduction in health care costs?

• Public model of cost-bundled that limit spending per patient (Medicaid)• Fee for service• Payer that pay out for sicker patients staying longer in hospital

• Performance or outcomes based incentives• Value based models• Perspective matters

• Cost to the patient and family• Cost to the hospital• Cost to the healthcare system• Cost to society

Page 42: Oct 24   CAPHC Lunch Symposium - Sponsored by Prolacta - Dr. Jae Kim

Economic Costs of NEC• One case of medical NEC is almost $75,000 USD• One case of surgical NEC is almost $200,000 USD

• NEC costs the health care system $5 billion USD annually (assume 10% incidence of NEC and 30% mortality)

• NEC constitutes 19% of the total costs for initial care for all newborns in the US

• 1909: the first milk bank was established in Vienna, Austria

• 1910: milk bank in Boston• North American history in milk banking is 100 years

old• 1974: Canada’s first milk bank in Vancouver• By early 1980’s 23 banks in Canada and 30

America reduced to 8 banks• 1985: Human Milk Banking Association of North

America (HMBANA) established • 2000: Vancouver Milk Bank almost closes

Donor human milk

PROS• Human specific• Bridges gap when

mother’s milk supply insufficient to meet infant’s requirements

CONS• Lower quality milk compared to fresh

milk• No cellular components or probiotics• Less protein due to maturity of milk• No lipase activity that may alter

digestion• Reduced bioactive components due

to processing• Reduced salts and vitamins

Recommendations for Donor Human Milk Banking

AAP Committee on Nutrition Statement (in press)CPS Committee of Nutrition (Kim and Unger) 2012• Donor human milk is an acceptable alternative to mother’s own milk for preterm infants

when it is not available• HMBANA or commercial donor banks are suitable sources• AAP

• The use of donor human milk in appropriate high-risk infants should not be limited by an individual’s ability to pay.

• Policies are needed to provide high-risk infants access to donor human milk on the basis of documented medical necessity, not financial status.

• Avoid unpasteurized milk sharing off Internet

• CPS• Recognized functions of the human milk bank should include the promotion of breastfeeding and

ongoing human milk research.• Pasteurized human donor breast milk should only be prescribed following written informed

consent from a parent or guardian.

Colostrum• Produced when the tight junctions in the mammary epithelium are

open• Paracellular transport of immunologically derived protective components

from mother’s circulation into milk

• Contain various immunomodulatory agents • Secretory immunoglobulin A [sIgA]• Growth factors• Lactoferrin• Anti-inflammatory cytokines

• More highly concentrated in mother’s of preterm infants

Evidence that oral colostrum care benefits preterm babies

• Seigel 2013• Retrospective cohort study of 369 inborn ELBW infants, 5 day treatment• Mortality, surgical NEC, SIP rates unchanged• Higher weight at 36 weeks (1666g vs. 1380g p<0.001)

• Lee 2015• Double blind, placebo-controlled trial of 45 infants <28 weeks gestation in South Korea• Increased urine levels of immunoglobulin A and lactoferrin• Significant decrease in clinical sepsis

• Sohn 2016• Impact of buccal administration of human colostrum on the oral microbiota of 12 VLBW

infants• OCC altered the colonization of the oral cavity with effects lasting after the intervention

ELBW = birth weight less than 1000 grams; VLBW = birth weight less than 1500 grams

Human Milk Microbiome

• Human milk has its own microbiota

• Phyla include Firmicutes, Proteobacteria and Actinobacteria

• Each mother’s microbiota is unique

• Donor human milk is pasteurized and therefore microbe-free

Human Milk Oligosaccharides (HMO)

• Third largest component in human milk!

• Small chain sugars (>150 variations)• Resist digestion• Substrate for beneficial intestinal

microflora• Support favorable bacteria population

in infant colon (“BIFIDOGENIC”)• Beneficial microflora stimulate the

developing immune system

Changing the clinical practice towards a dominant mother’s

milk culture in hospitals is very challenging but cost effective in promoting a

healthier long term outlook for premature infants

The future…

Exclusively Human

Human Milk

HumanHMF

Donor milk derived

additives

• Maternal lactation support• Donor human milk banking• Lacto-engineering science

• Addition of cream• Addition of protein• Human milk derivative bioactive additives

• Refinement of processing of human milk for preservation of function

• Increased cost benefit analysis for other long-term morbidities

Priorities1. Maternal lactation2. Donor human milk3. Human milk fortifiers4. Human milk derivatives

The SPIN Program Ten Steps

1. Have a NICU nutrition/human milk policy2. Educate all mother/baby staff in SPIN 10-steps3. Educate NICU families about optimal premature

infant nutrition4. Prevent extra-uterine growth restriction5. Standardize enteral feeding procedures6. Target 100% human milk nutrition 7. Maximize mothers’ milk production8. Optimize milk quality and safety9. Encourage skin-to-skin care and breastfeeding10. Plan a nutritional discharge from NICU

Take home points• Human milk is the single most powerful

intervention to optimize the best health outcomes in all babies

• In the absence of maternal milk, donor human milk is a superior substitute to formula

• Donor milk derivatives now support the provision of an exclusively human milk diet

• Initiating and maintaining a balanced gut microbiota begins with maternal milk

• Moving towards an exclusively human milk diet will show increasing cost savings and long-term healthcare benefits to preterm infants
