Because of the exploding cost of inpatient pediatrie care, the increasing importance of chronic disease and rehabilitation, and the growing emphasis on the prevention of disease and on well child counseling, the role of the outpatient department and of ambulatory pediatrie care has gained new significance. To undersore the need for new and imaginative approaches to patient care, teaching, and research related to outpatients, a Seminar on Ambulatory Pediatric Care was held in December 1964, to celebrate the opening of the renovated and refurbished Pediatrie Clinic at the Massachusetts General Hospital. The papers for this Seminar appeared in the August issue and are concluded in this issue.—Ed.
