3.7% of all RCTs in child health in developing countries were on neonatal care, or included neonatal outcomes
• Community care: – Skilled birth attendant delivery and essential
newborn care leads to 30-50% reduction in neonatal mortality in communities with very high neonatal mortality rates (e.g. >45/1000 live births)…
– Where the proportion of health facility deliveries is low…
– Where health systems are weak…

When mortality less than 25-30 per 1000 live births
• Community care still important – inequity
• Models of care needed at all levels of health service • Questions • What services are needed at
– health clinic – district hospital – referral hospital… – to establish minimal standard of neonatal care
• What current capacity exists? • What human resources are needed? • What technical resources are needed (physical facility
space, medications, equipment, guidelines, training)? • What are the appropriate referral criteria and
mechanisms?
Community based public health, sanitation, education, maternal nutrition
Facility-based obstetric and neonatal care, improved access to antibiotics, attention to thermal care, infant
nutrition and care of LBW and prematurity
Neonatal intensive care
Historical evidence
Models of care
• WHO/UNICEF Regional Action Plan for Neonatal Care
• Modelled on “The First Embrace” • Philippines hospital survey Sobel HL et al. Acta Paed. 2011
– 51 hospitals, obstetric and immediate newborn care – Widespread gaps in implementation of essential
newborn care (e.g. skin-skin contact, drying, thermal care)
– Unhelpful interventions common (early separation, suctioning)
Regional Action Plan 2013-2020
Goals 1. To reduce national NMR 10 per 1000 or less in all member states 2. To reduce sub-national NMR 10 per 1000 or less
Models of care
• Quality improvement approach • What services are needed at
– health clinic – district hospital – referral hospital… – to establish a minimal standard of neonatal care
• What current capacity exists? • What human resources are needed? • What technical resources are needed (physical facility
space, medications, equipment, guidelines, training)? • What are the appropriate referral criteria and
mechanisms?
Models of care: Health clinics • Newborn resuscitation • Support for breastfeeding • Thermal protection, skin-to-skin contact • Infection prevention: general hygiene, hand washing, cord care • Eye infection prophylaxis • Immunization and Vitamin K prophylaxis • Identification, treatment or referral of signs of severe illness, injury or
malformation (IMCI, referral guidelines) • Birth registration • Counseling regarding newborn care, care-seeking, health promotion
including immunizations and avoidance of indoor air pollution • Developmental care including newborn stimulation and play • Follow up visits for vaccines, growth monitoring • Family planning
Models of care: District and provincial hospitals
• All interventions at the clinic level, plus… • A special care / high dependency nursery • Management of a newborn with serious illness:
– Oxygen and oximetry – Apnoea: monitoring and prevention – Warming (includes KMC) – Breast feeding and prevention of hypoglycaemia – Safe administration of intravenous fluids – Standard antibiotics
• Guidelines for management and referral of common conditions: – Preterm and VLBW babies – Severe respiratory distress – Severe infection – Severe birth asphyxia – Severe jaundice - phototherapy – Malformations and common surgical conditions
• Audit • Prevention of nosocomial infection
Models of care: Referral hospitals
• All interventions at the clinic and district hospital level, plus…
• Respiratory distress: – CPAP / high flow nasal prong oxygen
therapy • Surgical services for neonates • Care for the VLBW baby (weight for
referral depending on access and capacity at district / provincial hospital)
• Exchange transfusion for severe jaundice

Models of care: referral criteria Indications for referring newborns to hospital • Birth-weight between 1-1.5 kg • Birth-weight between 1.5–2.0 kg if:
¨ Respiratory distress or apnoea ¨ Signs of sepsis
• Birth asphyxia • Severe respiratory distress • Severe infection
¨ Sepsis ¨ Meningitis ¨ Osteomyelitis / septic arthritis
• Any infection that does not improve after 48 hours of appropriate treatment • Severe abdominal distension • Signs of shock (>3 seconds for capillary refill, weak pulse, cold hands) • Congenital abnormalities:
¨ Suspected congenital heart ¨ Open abdominal lesions ¨ Ambiguous genitalia ¨ Imperforate anus ¨ Bile (green) stained vomiting ¨ Frequent vomiting and lots of saliva in the first few hours of life ¨ Pain and swelling of the testes or the inguinal area
• Recurrent apnoeas (>3 periods of no breathing for longer than 20 seconds per day) • Coma and / or convulsions • Uncontrolled bleeding despite Vitamin K injection • Pallor • Severe jaundice or jaundice that lasts longer than 2 weeks • Unexplained poor weight gain for more than 2 weeks after birth Call or radio National Referral Hospital or provincial hospital
Models of care: referral mechanisms
• Communication • Transport • Funding • The model in Fiji
Other resources
• Training on the WHO Pocket Book of Hospital Care – Training in care of the neonate with LBW,
sepsis, birth asphyxia • Assessment tools for neonatal care standards at
hospitals • Appropriate technology • Posters • Simple standardized data reporting system
Training strategies • Training CD-ROM
NEONATAL RESUSCITATION
Neonatal resuscitation can be highly effective even without oxygen using a self-inflating resuscitation bag & mask All newborn babies should be given their first dose of BCG and Hepatitis B vaccines and a dose of vitamin K Babies should be breast-fed within the first hour of birth
Produced by the Paediatric Society of PNG and the World Health Organization 2008
Systematic approach to the use of oxygen
• Concentrators • Oximetry • Bubble-CPAP
Simple systems of data for surveillance
Simple standardised outcome reporting

Sepsis
• Half a million neonatal deaths each year • WHO recommends treatment with
penicillin / ampicillin and gentamicin • Many countries use third-generation
cephalosporins to treat neonatal sepsis
• 19 studies, 13 countries, >4000 cases of bacteraemia • Staph aureus, Klebsiella spp. and E. coli accounted for
55% (39–70%) • Penicillin/gentamicin had comparable in vitro coverage to
third-generation cephalosporins (57% vs 56%) • Resistance to the combination of penicillin and
gentamicin and to third-generation cephalosporins occurs in more than 40% of cases
Implications • How to determine criteria for second-line therapy that are
implementable in resource-limited settings • How to ensure recommendations are effective but
minimise the development of further resistance • How to make available more expensive or higher-
generation antibiotics in resource-limited developing countries but ensure their use is based on evidence
• How to address the poor state of bacteriology services in most developing countries and improve local surveillance data
Summary
• Models of care at primary, district, referral level • It can be done…and saves lives • Tools available • Implementation science • Monitor neonatal outcomes – it can be done • Antibiotic stewardship needed
How to start • What services are needed at
– health clinic – district hospital – referral hospital… – to establish a minimal standard of neonatal care
• What current capacity exists? • What human resources are needed? • What technical resources are needed (physical facility
space, medications, equipment, guidelines, training)? • What are the appropriate referral criteria and
mechanisms?
