Role of the Pediatrician T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=6720001 RD 2024/10/13 AB As pediatrics and the delivery of children’s health care enter the 21st century, the role of the pediatrician continues to evolve and change. Guided by the knowledge, skills, and tools that the profession has accumulated over many decades, pediatricians must strategically respond to changing conditions, health determinants, and epidemiology of childhood as well as to shifting social and cultural norms of what constitutes healthy child development. Our knowledge of the pathophysiology of many diseases has evolved from simple causal models based on germ theory to more complex notions of gene-environment interactions. As pediatric care has triumphed over many infectious diseases and made significant strides in the management of chronic disease, newer morbidities have emerged, including a growing prevalence of developmental, behavioral, and mental health conditions. To impact child health, 21st-century pediatricians must provide care with an expanded concept of healthy child development and must acquire skills to effectively practice in collaboration with other individuals and entities involved in promoting and supporting that development.
