QuickStats: Percentage of Outpatient Department (OPD) Visits in Which Only a Mid-Level Provider Was Seen and in Which Both a Physician and a Mid-Level Provider Were Seen --- United States, 1993--2004

* Data reflect average annual estimates for each 2-year period.

Since 1993--1994, the annual number of OPD visits increased by 39% to approximately 90 million during 2003--2004. Although the majority (80%) of OPD patients were seen by a physician during 2003--2004, the role of mid-level providers (e.g., physician assistants, nurse practitioners, and midwives) became more prominent. Since 1993--1994, the percentage of visits in which only a mid-level provider was seen increased from approximately 6% to 11%. During the same period, the percentage of visits in which both a mid-level provider and physician were seen did not change, and the percentage of visits in which only a physician was seen decreased by 4%, from 81% to 78%.
