where the assessment takes place after the patient has gone home. misdiagnosis is the leading cause of medical error in outpatient facilities. when the u.s. institute of medicine’s groundbreaking 1999 report, to err is human, found up to 98,000 hospital patients die from preventable medical errors in the u.s. each year, early efforts focused on inpatient safety. while patient safety efforts have focused on inpatient hospital settings for more than a decade, medical errors are even more likely to happen in a doctor’s office or outpatient clinic or center. day patient a day patient or (day-patient) is a patient who is using the full range of services of a hospital or clinic but is not expected to stay the night. the term was originally used by psychiatric hospital services using of this patient type to care for people needing support to make the transition from in-patient to out-patient care. however, the term is now also heavily used for people attending hospitals for day surgery. alternative terminology because of concerns such as dignity, human rights and political correctness, the term "patient" is not always used to refer to a person receiving health care. other terms that are sometimes used include health consumer, healthcare consumer, customer or client. however, such terminology may be offensive to those receiving public health care, as it implies a business relationship. in veterinary medicine, the client is the owner or guardian of the patient. these may be used by governmental agencies, insurance companies, patient groups, or health care facilities. individuals who use or have used psychiatric services may alternatively refer to themselves as consumers, users, or survivors. in nursing homes and assisted living facilities, the term resident is generally used in lieu of patient. similarly, those receiving home health care are called clients. patient-centered healthcare
