An operational definition could not be specified at the time of publication.
The proposed national data source is the National Health Interview Survey (NHIS), CDC, NCHS.
The proposed numerator is the number of persons who report that they delayed or had difficulty getting emergency medical care because of any one of several possible barriers, including unsure if emergency medical care needed; needed to contact health care provider or health plan; could not take time off from work; needed child care; did not have transportation; ambulance did not arrive quickly; no health insurance; health plan requires co-payment; health plan requires pre-authorization; concerned that health plan would not pay for emergency visit; referred out of the emergency room without treatment; long wait in the emergency room/ or emergency medical facility; or an other specified reason.
The proposed denominator is the number of adults in the survey population aged 18 years and older weighted to the U.S. civilian, noninstitutionalized population.
The proposed questions to be used to obtain the data are scheduled to be included in the 2001 NHIS.
