Ambulatory Care


Medical care is divided into two categories - inpatient and ambulatory care. Ambulo is Latin for walk, so you can think of ambulatory care as patients walking in and out of the facility on the same day. Much of ambulatory care takes place in small physician practices. This is rapidly changing as mergers and consolidations bring more practices under the auspices of a larger hospital. Many medical school graduates in ambulatory care are choosing to become hospital employees instead of working inindependent practice settings. 

Ambulatory care settings:

When looking at office visits by type, including hospital clinics, primate offices, community health centers and HMOs, we generally divide them into primary care visits and specialty care visits.   Specialty care if further divided into medical and surgical specialties.

Primary Care


"Primary care is the level of a health services system that provides entry into the system for all new needs and problems, provides person-focused (not disease-oriented) care over time, provides care for all but very uncommon or unusual conditions, and coordinates or integrates care, regardless of where the care is delivered and who provides it. It is the means by which the two main goals of a health services system, optimization and equity of health status, are approached."

The acronym PCP has two meanings. I refer to the broader term Primary Care Providers, which may be a physician, nurse practitioner or physician's assistant. You will also see this used for the more narrow Primary Care Physician. Primary care providers see patients in a range of locations:  hospital outpatient departments, free-standing practices, community health centers*, schools, and as home visits.

Community health centers (CHCs)  are located in underserved areas (urban and rural). These organizations provide comprehensive primary care services to those in their geographic area. These are safety-net providers and do not turn away uninsured patients. CHCs vary in their degree and mode of federal support, they are all are not-for-profit organizations. Some CHCs are Federally Qualified Health Centers (FQHC).
