Residency Training	3 years Pediatrics (categorical)	Internal Medicine: 3 yr (adult only). Family Medicine: 3 yr (all ages, OB, procedures).
Focus	Growth/development, congenital, infectious, behavioral, preventive (vaccines, screening), family dynamics	Chronic disease management (HTN, DM, CAD, COPD), multi-morbidity, preventive screening, acute adult illness
Procedural Skills	Lumbar puncture, intubation (neonatal/peds), sedation, circumcision, minor suturing	Central lines, arthrocentesis, paracentesis, thoracentesis, colonoscopy (some FM), skin procedures
Board Certification	American Board of Pediatrics (ABP)	ABIM (Internal Medicine) or ABFM (Family Medicine)

When to Choose a Pediatrician

• Patient is <18 (or <21 for complex chronic conditions).
• Developmental, behavioral, or growth concerns.
• Vaccination schedule management.
• Congenital/genetic condition coordination.
• Adolescent confidential care (sexual health, mental health).

When to Choose an Internist / Family Physician

• Patient is adult (≥18).
• Multiple chronic conditions (diabetes, HTN, CKD, HF).
• Age-related screening (colonoscopy, mammogram, AAA, bone density).
• Perioperative medical optimization.
• Family medicine: whole-family care, OB, procedural breadth.

Transition of Care

Pediatric → adult transition typically 18–21 years. Structured transition programs (Got Transition framework) improve outcomes for youth with special health care needs.
