Y2K medical disaster preparedness in New York City: confidence of emergency department directors in their ability to respond.

OBJECTIVES: To study the preparedness New York City for large scale medical disasters using the Year 2000 (Y2K) New Years Eve weekend as a model. METHODS: Surveys were sent to the directors of 51 of the 9-1-1-receiving hospitals in New York City before and after the Y2K weekend. Inquiries were made regarding hospital activities, contingencies, protocols, and confidence levels in the ability to manage critical incidents, including weapons of mass destruction (WMD) events. Additional information was collected from New York City governmental agencies regarding their coordination and preparedness. RESULTS: The pre-Y2K survey identified that 97.8% had contingencies for loss of essential services, 87.0% instituted their disaster plan in advance, 90.0% utilized an Incident Command System, and 73.9% had a live, mock Y2K drill. Potential terrorism influenced Y2K preparedness in 84.8%. The post-Y2K survey indicated that the threat of terrorism influenced future preparedness in 73.3%; 73.3% had specific protocols for chemical; 62.2% for biological events; 51.1% were not or only slightly confident in their ability to manage any potential WMD incidents; and 62.2% felt very or moderately confident in their ability to manage victims of a chemical event, but only 35.6% felt similarly about victims of a biological incident. Moreover, 80% felt there should be government standards for hospital preparedness for events involving WMD, and 84% felt there should be government standards for personal protective and DECON equipment. In addition, 82.2% would require a moderate to significant amount of funding to effect the standards. Citywide disaster management was coordinated through the Mayor's Office of Emergency Management. CONCLUSIONS: Although hospitals were on a heightened state of alert, emergency department directors were not confident in their ability to evaluate and manage victims of WMD incidents, especially biological exposures. The New York City experience is an example for the rest of the nation to underscore the need for further training and education of preparedness plans for WMD events. Federally supported education and training is available and is essential to improve the response to WMD threats.

A longitudinal study of pain in hospice and pre-hospice patients.

Pain continues to be a very formidable foe in the care of the hospice patient. The incidence among hospice admissions may range from 50 to 80 percent. With such a high initial incidence of pain, the rapidity with which pain can be controlled becomes a very high priority for the hospice effort. The assessment and management of pain in a home-based hospice program presents some unique problems--and opportunities, in that much of this work is done by hospice nurses on site, rather than by the physician, who might remain quite removed from the process. In the study described below, 250 consecutive admissions to either a hospice, or pre-hospice (bridge) program were assessed for pain on admission. Those with pain scores of 5 or greater (on a 1 to 10 scale) were followed daily for 15 days by phone to reassess pain and treatment effects. Of the 250 consecutive patients surveyed, 41 (16 percent) gave pain scores of 5 or greater. Mean pain scores for the 41 patients dropped to < 5 within 24 hours of admission.

Dural sinus thrombosis: verification with spin-echo techniques.

Although MR imaging is being used increasingly to detect dural sinus thrombosis, accurate evaluation of images has often been hindered by the presence of artifacts, especially flow-related enhancement, that may simulate intraluminal clot. We tried an approach with spin-echo techniques to eliminate flow-induced artifacts and, thus, facilitate the diagnosis of dural sinus thrombosis. In this investigation, a nonselective single-section spin-echo verification method was used as a prototype of this approach. Both patients and an experimental flow phantom were used to test the validity of this concept. Clinically, thrombosis was seen to persist as isointense or highly intense signal in the vascular lumina with the specialized sequence, while flow-related artifacts were replaced by hypointense signal, but not by signal void. These same changes were examined both quantitatively and qualitatively in the flow phantom by using varying velocities of flow. Although our clinical investigation concerns suspected dural sinus thrombosis, the principles of these specialized spin-echo techniques can be applied successfully throughout the head to eliminate certain flow-related artifacts.
