    Study Notes

    Introduction to Pediatrics

    • Saudi Arabia's youth and children population represents 67% of the total population according to a 2020 report.
    • Children (0-14 years) make up 30.3% of the population.
    • Youth (15-34 years) make up 36.7% of the population.
    • Child maltreatment is a significant risk factor for disability and has increased from 21.6% in 1970 to 44.9% in 2017.

    Pediatric Vulnerability to Medication Error

    • Medication errors in pediatrics occur at a rate of 5.7 per 100 orders.
    • Pediatric medication errors are 3 times more likely to cause harm than in adults.
    • Factors contributing to medication errors in pediatrics include:
      • Developmental pharmacokinetics
      • Weight-based dosing
      • Extrapolation of doses from adult studies
      • Off-label drug use
      • Lack of standardized drug formulations
      • Communication barriers

    Role of a Pediatric Pharmacist

    • Pediatric pharmacists should be knowledgeable about medication therapy and have the necessary skills to apply it.
    • Responsibilities include:
      • Medication selection and use
      • Monitoring effectiveness and toxicity
      • Preventing medication errors
      • Patient and caregiver education
      • Contributing to knowledge through research

    Pediatric Age Classification and Definitions

    • Gestational Age (GA): Time from the first day of a woman's last menstrual period to the birth of the baby
    • Conceptional Age: Time between conception and delivery (more accurate for pregnancies achieved through assisted reproductive technologies).
    • Postnatal Age (PNA): Time elapsed since birth.
    • Postmenstrual Age (PMA): GA + PNA.
    • Corrected Age: Chronological age minus the number of weeks born before 37 weeks of gestation.
      • Corrected age = PNA - (37 - actual GA)
      • Reported up to 3 years of age for premature infants.
    • Pediatric Age Classifications:
      • US Department of Health and the Food and Drug Administration (FDA):
        • Infancy: Between birth and 2 years of age
        • Childhood: From 2 to 12 years of age
        • Adolescence: From 12 to 21 years of age
      • American Academy of Pediatrics (AAP): Upper age limit of pediatrics is 21 years.
      • Center of Disease Prevention (CDC): Upper age limit of pediatrics is 20 years.
    • NICHD (Eunice Kennedy Shriver National Institute of Child Health and Human Development in the USA):
      • Preterm Neonatal: Born before the full gestational period (less than 37 weeks).
      • Term Neonatal: Born between 37 and 41 weeks of gestation.
      • Post-Term Neonatal: Born after 41 weeks of gestation.
      • Infancy: From birth to 1 year of age.
      • Toddler: From 1 to 3 years of age.
      • Preschool: From 3 to 5 years of age.
      • School age: From 5 to 12 years of age.
      • Adolescence: From 12 to 18 years of age.
      • Young Adulthood: From 18 to 25 years of age.
