Ambulatory medicine

Ambulatory care or outpatient care is medical care provided on an outpatient basis, including diagnosis, observation, consultation, treatment, intervention, and rehabilitation services. This care can include advanced medical technology and procedures even when provided outside of hospitals.

Ambulatory care sensitive conditions (ACSC) are health conditions where appropriate ambulatory care prevents or reduces the need for hospital admission (or inpatient care), such as diabetes or chronic obstructive pulmonary disease.

Many Medical Investigations and treatments for acute and chronic illnesses and preventive health care can be performed on an ambulatory basis, including minor surgical and medical procedures, most types of dental services, dermatology services, and many types of diagnostic procedures (e.g. blood tests, X-rays, endoscopy and biopsy procedures of superficial organs). Other types of ambulatory care services include emergency visits, rehabilitation visits, and in some cases telephone consultations.

Ambulatory care services represent the most significant contributor to increasing hospital expenditures and to the performance of the health care system in most countries, including most developing countries.
