  1. Global Pediatric Advanced Life Support: Improving Child Survival in Limited-Resource Settings Mark Ralston, MD MPH Dept Pediatrics, Naval Hospital Oak Harbor, WA Assistant Prof Pediatrics, USUHS

  2. Global Under-Five Mortality • Occurrence: 99% occurs in LR settings6 Sub-Saharan Africa: 49% South Asia: 33% Other: 17% • Leading single causes (deaths/year):56 Pneumonia: 1.396 million (18% total) Diarrhea: 0.801 million (11% total) Total: 7.6 million (2010) • Infectious cause:56 64% total

  3. “Deaths occur outside the vision of health services, mainly in the home, with the majority occurring in the poorest households in the poorest communities.” Edward (Kim) Mulholland, MD London School of Hygiene and Tropical Medicine Menzies School of Health Research, Darwin Australia

  4. United Nations Millennium Development Goal 4 • UN MDG 4 = 2/3 reduction in U5M by 2015 (from 13 million annual deaths in 1990)5 • 2015 Goal = 4.3 million annual deaths

  5. Combination Approach for U5M Reduction • Prevention: eg, breastfeeding until 6 mos, clean water/hygiene, vaccines, micronutrients (zinc, Vitamin A), complementary feeding • Treatment (weak link in LR settings is emergency & critical care)8,10,15

  6. Global causes of childhood deaths in 201056

  7. Pediatric Advanced Life Support in LR Settings • Definition: emergency management beyond CPR/AED in children beyond newborn period • Achievements: some gains in management of severe infection & shock • Reality: often ALS is incomplete (where nearly all global pediatric deaths occur!)

  8. Limited Access to Resources References: 3,4,8-23

  9. Reported Limited Resources for Children in Low-Income Settings • Oxygen or equipment to detect hypoxemia are often unavailable to critically ill children24

  10. Reported Limited Resources for Children in Low-Income Settings • Guinea-Bissau: 16% acutely ill children die enroute to or while waiting for care25 • Kenya: insufficient basic items to treat critical illness are unavailable at district hospitals19 • Uganda: 1/3 U5M (pneumonia) occurs at home;26 1/3 children needing referral for hospital care receive referral after 2 wks27

  11. Reported Limited Resources for Children in Low-Income Settings • Tanzania: ~50% children referred to hospital take > 2 days to arrive8 • India: effective transport system is non-existent11 • Mongolia: no infrastructure exists to implement available sepsis guidelines3 • Brazil: no services for shock is frequent30

  12. Table 1: Levels of Pediatric ALS Capability Note: see hardcopy Table 1 for full details; higher level capability exists but is uncommon16

  13. Modifying ALS Guidelines to Reflect Different Disease Spectrum • Sepsis: • Severe infection (malaria)/Shock: bolus-fluid resuscitation (NS/Albumin) in children associated with increased 48 hour mortality38 • Dengue Shock: early aggressive fluid resuscitation with judicious fluid removal & early colloid may be preferred in children39-42

  14. Modifying ALS Guidelines to Reflect Different Disease Spectrum • Severe Acute Malnutrition • Infection: children have more critical presentation, different causative organisms, higher mortality2,43-48 • Shock: aggressive fluid resuscitation may have adverse effects16,49

  15. Modifying ALS Guidelines to Reflect Different Disease Spectrum • Micronutrient Deficiencies • Vitamin A Deficiency: mortality risk due to diarrhea, measles & malaria in children is increased by 20-24%50 • Zinc Deficiency: mortality risk due to diarrhea, pneumonia & malaria in children is increased by 13-21%51

  16. Modifying ALS Guidelines to Reflect Different Disease Spectrum • Measles • Pneumonia & diarrhea are common co-morbidities in critically ill children52 • Children suffer higher mortality risk2 • HIV • Children have different causative organisms, higher rates antibiotic resistance/polymicrobial disease/M&M2,53-55

  17. Impacting U5M with Simple Inexpensive ALS Interventions

  18. Lack of Infrastructure for Pre-hospital Emergency Care • Insufficient resources • Knowledge gaps: occur among lay caretakers for both recognition & treatment of illness65 • Emergencies (10-20% of visits): handled by IMCI with “urgent referral to hospital” 35,66-68 • Deficient referral processes & inadequate transport services9-12,25,27,29,33

  19. Providing Pre-hospital Emergency Care by Primary Care System • Expected by local community10,34 • Shown to be cost-effective13,34 • Provided effectively by non-medical personnel34 • Requires basic supplies/equipment which have been requested35

  20. Reduced U5M by Pre-hospital Community Case Management

  21. Proposed Solutions for Improved Pre-hospital Pediatric Emergency Care • Define minimum standards for LR settings • Integrate ALS guidelines within IMCI • Equip first-level responders for basic stabilization • Determine more specific IMCI referral criteria for serious conditions • Utilize simple modes of emergency transport

  22. Poor Quality Hospital Care • Poor quality is widespread10,15,17, 19,30, 31,69,70 • ~50% deaths of hospitalized children in LR settings occur within 24 hours of admission

  23. Proposed Solutions for Improved Hospital Emergency & Critical Care NOTE: Strategies to improve overall quality of care at hospital level in low-income countries are in progress69 • Update ETAT guidelines (latest version 2005)18,75-77 • Consider “limited-resource ICU” offering continued, time-sensitive treatment practical to local needs & limitations4,78

  24. Systematic Approach to Patient Assessment & Categorization of Illness • Largely missing from existing ALS management in LR settings8,15,18,30 • Improves early recognition of critical conditions, treatment & outcomes (eg, pneumonia and shock)4,22,26,30,33,36,43,70,72,79-81

  25. Existing Pediatric ALS Courses • Mostly originate in full-resource settings • Exception found in Africa: ETAT plus Admission Care Course16,18,37,75-77,82 • Mostly applicable to full-resource settings • Lack universal applicability despite international acceptance18,32,70,75,76,83 • Effectiveness in improving outcomes in developing world has not been shown84

  26. Existing Pediatric ALS Courses • Offer variety of curricula, including: • “ABCDE” approach to patient assessment • Standardized system of categorizing critical illness • Treatment of specific emergency/trauma conditions • Revised curriculum with evidence-based application for LR settings would expand usefulness worldwide • Ideally should be taught from community health level to larger hospitals

  27. Table 2: Substitute Pediatric ALS Interventions in LR Settings Note: see hardcopy Table 2 for full details

  28. Empiric ALS Guidelines • Most existing pediatric ALS Guidelines in LR settings are empirical, not evidence-based16,24,102,109 • Avoidance of O2 masks for free-flow O2 delivery • Use of small fluid bolus then blood in SAM/shock • Use of broad-spectrum antibiotics in sepsis • Justification for empirical guidelines: pragmatism (eg. O2 mask consumes less O2 than nasal prongs) & lack of evidence110

  29. International Evidence-Based ALS Guidelines for LR Settings • Evidence-based ALS Guidelines are needed: MANAGEMENT16,32,43,46,49,54,66,95,111,112 • Fluid resuscitation in severe infection/shock • Antibiotic management in sepsis • Management of SAM (eg. sepsis, fluid resuscitation, nutrition) TRAINING12,33,113 • Airway skills • Implementing O2 System (concentrators/pulse oximetry)

  30. International Pediatric ALS Guidelines: Hypoxemia & Pulse Oximetry • Clinical indicators of hypoxemia:74 central cyanosis; nasal flaring; inability to drink or feed; grunting; lethargy; consider also severe chest retractions, respiratory rate > 70/min, head nodding74 • Pulse oximetry:74 use to detect hypoxemia & to guide oxygen therapy74

  31. International Pediatric ALS Guidelines:Oxygen Therapy • Indications:74 SpO2 < 90% (< 2500 m above sea level) SpO2 < 87% (> 2500 m above sea level) • Delivery systems:74 nasal prongs are preferred in children < 5 y; use nasal or nasopharyngeal catheters if nasal prongs are unavailable

  32.

  39. International Pediatric ALS Guidelines:Fluid Resuscitation-Acute Diarrhea • Severe dehydration (fluid deficit >10% BW):114 • if IV therapy unavailable, give ORS (NG/oral) 120 mL/kg over 6 hours (20 mL/kg/hour) • with improved LOC give ORS (oral/NG) 75 mL/kg over 4 hours in frequent small amounts • + replacement of ongoing losses

  40. International Pediatric ALS Guidelines:Antibiotics-Bloody Diarrhea • Ciprofloxacin 15 mg/kg/dose orally twice daily for 3 days74 • If treatment failure, Ceftriaxone 50-80 mg/kg/dose IV/IM daily for 3 days74 • Follow guidelines according to local sensitivities74
