Children's Hospital Boston is a 396-bed comprehensive center for pediatric health care. As one of the largest pediatric medical centers in the United States, Children's offers a complete range of health care services for children from birth through 21 years of age. (Our Advanced Fetal Care Center can begin interventions at 15 weeks gestation, and in some situations, we treat adults.)Children's records approximately 22,600 inpatient admissions each year, and our 204 specialized clinical programs schedule more than 527,500 visits annually. Additionally, the hospital performs 23,000 surgical procedures and 170,000 radiological examinations every year.\Children's is the primary pediatric teaching hospital of Harvard Medical School, at which most of our physicians hold faculty appointments.It is also home to the world's largest research enterprise based at a pediatric medical center. Since 1869, our discoveries have benefited both children and adults. More than 600 scientists, including eight members of the National Academy of Sciences, eleven on-staff members of the Institute of Medicine and twelve members of the Howard Hughes Medical Institute, comprise Children's research community. Our current initiatives have attracted a record $176 million in funding, including more federal funding than is awarded to any other pediatric facility.In the John F. Enders Pediatric Research laboratories, named for the Children's researcher and Nobel Prize recipient who cultured the polio and measles viruses, hundreds of laboratory researchers and physician investigators search for answers to some of the most perplexing diseases.In 2003, a generous philanthropic gift made the 295,000 square foot Karp Family Research Laboratories possible. The building increased our research space by more than 60 percent. The Karp family gift is just one of many important gifts that support Children's vital research enterprise
