Objective:
To determine the mechanism by which managed care organization (MCO) enrollees enter the emergency medical services (EMS) system.
Methods:
All enrollees belonging to the region's largest MCO and transported to emergency departments by a paramedic-level municipal EMS system were identified from billing records. Dispatch logs were examined to determine the time and origin of the call to the 911 communication center. Patient care records were used to obtain age, the level of care delivered (advanced or basic life support), and whether the patient received any medications while out of hospital. Hospital admission was also determined.
Results:
Over a six-month period, 195 enrollees were transported. Three modes of 911 EMS system entry were identified: group I-enrollees who called 911 directly; group II-enrollees who called the MCO triage center, who then called 911 on behalf of the patient; and group III--enrollees who were sent to the MCO health center for evaluation, and subsequently the MCO called 911 to transfer the patient to the hospital. Of the 195 patients transported to the emergency department, the dispositions of 108 (55%) patients were obtained. Group I (n = 109) patients were more likely to be transported in the evening (3 PM to 11 PM), less likely to require advanced life support therapies, and less likely to be admitted to the hospital when compared with groups II (n = 32) and III (n = 54) patients. Group III patients were the most likely to receive advanced life support care and require admission to the hospital.
Conclusion:
The majority of MCO enrollees called 911 directly, and were most likely to do so during evening hours. Enrollees who called 911 directly (group I) had a trend toward lower acuity, based on the lowest ALS utilization of any group. Those enrollees who most frequently required advanced life support were those who received initial treatment at the MCO center prior to EMS transport. Though EMS system-specific, this type of descriptive analysis is helpful in assisting both EMS systems and MCOs to better assess utilization of 911 EMS resources by MCO enrollees. This study also challenges the prudent layperson paradigm.

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
