Medically Unnecessary Pediatric Ambulance Transports: A Medical Taxi Service?

Abstract

Objective: To characterize ambulance utilization i n a pediatric population and pediatric emergency physicians' judgment of the medical need for ambulance transport. Methods: A convenience sample of ambulance transports were studied prospectively during a 5-week period.Exclusion criteria included transfer from another medical facility, study physician not available, need for immediate resuscitation, or trauma team activation. A questionnaire completed by the physician assessed medical need for the ambulance based on chief complaint, general appearance, vital signs, and ambulance run sheet information. A separate questionnaire was administered to the parents regarding reasons for ambulance use and other available means of transportation. Caregivers were contacted by telephone 2-3 days later to determine the mode of transportation home and the clinical outcome. Results: Of 172 eligible patients, 92 (53%) were enrolled. Most (61 %; 56/92) transports were considered medically unnecessary. Interestingly, 40% (37/92) of the subjects had no other means of transportation; 86% (32/37) of ambulance transports for this group were judged medically unnecessary. Overall, 86% (79/92) of families had not called their physician. There was no association between having spoken with the physician and medical need for an ambulance. Many (82%; 46/56) Medicaid transports were judged medically unnecessary. Overall, follow-up was achieved for 91% (85/92) of the patients. No patient for whom transport was medically unnecessary bad a repeat ED visit for the same complaint or required admission. Most patients (74%; 68/92) returned home without any assistance. Among the medically unnecessary transports, 52% (32/ 60) of the caregivers cited no other means of transportation, yet 34% (1 1/32) of these patients returned home by private car. Conclusions: Most pediatric ambulance transports in this sample, which excluded patients requiring immediate resuscitation or trauma team care, were judged to be medically unnecessary. Caregivers often use an ambulance as a convenience or as the only means of transportation. An alternate, less resource-intensive transportation system may be more appropriate for this population.

Pediatric Use of Emergency Medical Services: The Role of Chronic Illnesses and Behavioral Health Problems

“…7,20 High rates of utilization of emergency health services among Black male youths have been explained by their particular disparities in access to health care and greater use for non-emergent issues, as indicated in the Affordable Care Act. 6 However, a recent study suggest this pattern of emergency health services use may be changing. 21 Studies suggest the increasing role of impediments to patients’ regular source of healthcare in contributing to pediatric use of EDs.…”

Descriptive Analysis of Patients’ EMS Use Related to Severity in Tokyo: A Population-Based Observational Study

“…Richardson et al reported that having no other means of transportation was the main reason for use of emergency medical transports, especially in big cities. [9] Moreover, because the Japanese family has shifted to the nuclear family, people might ask other non-family people whether they should call an ambulance or not. Those who give advice are usually laypersons and may overestimate the seriousness of a patient’s illness and thus may recommend them to call an ambulance.…”
