Abstract
A major focus of US health care systems is ensuring timely patient access to subspecialty care. This article describes the experiences of a large children's hospital after implementation of clinic session standardization and template optimization. Outpatient specialty clinic sessions were standardized to 4-hour periods, and all unfilled complex appointment slots were made available for any appointment type within 72 hours of the clinic date. Three high-demand outpatient clinical services achieved increased aggregate potential and completed outpatient appointments over a 2-year period. These improvements were mostly due to an increase in providers and were not always coupled to shorter patient lag times.
