Practice guidelines and performance measures in emergency medical services for children

Practice guidelines and performance measures are critical elements of an effective quality improvement process for emergency medical services for children (EMSC). Practice guidelines address the clinical management of individual patients, and performance measures assess the quality of care delivered to a population. The public and private sectors have invested considerable resources in developing practice guidelines and performance measures to improve the quality of health care services. As organizations continue development efforts, health care professionals who are actively involved in emergency care must collaborate to develop guidelines that address the unique physiologic, psychologic, and cultural needs of children. The Emergency Medical Services for Children Managed Care Task Force recommended the development of a series of white papers to focus on issues related to practice guidelines and performance measures in EMSC. The Maternal and Child Health Bureau, Health Resources and Services Administration, the National Highway Traffic Safety Administration, and the Robert Wood Johnson Foundation jointly sponsored the project. The paper was developed by a panel selected from a pool of experts in managed care, quality improvement, and emergency medical services. After a review of the literature, the panelists met to discuss critical issues related to practice guidelines and performance measures in EMSC. The panelists developed recommendations that can serve as resources for managed care organizations, health care providers, professional associations, and governmental policy makers. The panel recognized the lack of nationally recognized pediatric emergency care guidelines and performance measures and called for immediate action in these areas.     

MRA in patients with cerebrovascular disease. Considerations of clinical effectiveness

Objective:
To establish in which clinical contexts cerebral MR angiography (MRA) is routinely carried out in a neurological university department and to describe its clinical impact.
Material and Methods:
Medical records, reports of findings and documentation of imaging examinations carried out in all 69 patients referred to the Department of Radiology from the Department of Neurology between 1995 and 1998 for cerebral MRA were evaluated. The clinical impact of all imaging findings was assessed on the basis of the medical records.
Results:
Circulatory disturbances in the vertebrobasilar arteries (n=34) were the most frequent indication for investigation. MRA followed CT or duplex sonography in 66 of the 69 patients with a mean delay of 8 days. MRA was considered diagnostically inferior to conventional MR in 11 cases, comparable in 30 and superior in 25. Comparing MRA and duplex sonography, the corresponding figures were 12, 29 and 23. In retrospect, 56 MRAs were judged unnecessary.
Conclusion:
Controlled clinical studies on optimal use of MRA are needed to avoid wasting resources and to exploit the method's full diagnostic potential in appropriate cases.
