Assessment of hospital disaster plans for conventional mass casualty incidents following terrorist explosions using a live exercise based upon the real data of actual patients.

PURPOSE: The National Committee for Hospital Preparedness for Conventional Mass Casualty Incidents and the Hospital Preparedness Division of the Home Front Command are in charge of preparing live exercises held yearly in public hospitals in Israel. Our experience is that live exercises are limited in their ability to test clinical decision making and its influence upon incident management. A live exercise was designed upon real patient data and tested in several public hospitals. The aim of the manuscript is to describe the impact of this new format on clinical decision making in large-scale live exercises. METHODS: A database of histories, physical examination findings, laboratory results and imaging results for 420 patients treated following terrorist explosions was created using information derived from actual patient encounters. Similar information for 100 patients treated following motor vehicle accidents was also collected. Information from the database was used to create victim profiles used during the course of exercises held in eight public hospitals with 60-800-bed capacities. RESULTS: Before implementing the new injury tags, no conclusions could be made concerning the quality of clinical decision making. Conducting the exercise using the new format helped identify deficiencies in the hospital disaster plan in triage, emergency department management and in the proper utilisation of resources such as radiology, operating rooms and the secondary transfer of patients. CONCLUSION: Previous knowledge of patient diagnoses and resource needs allow the identification and quantification of deficiencies and problems identified in clinical decision making, resource utilisation and incident management.

[Spinal cord compression caused by metastasis of soft tissue hepatocarcinoma]. / Compresión medular por metástasis de partes blandas de hepatocarcinoma.

More than 90% of hepatocellular carcinoma (HCC) arise in a chronical hepatitis. When HCC is diagnosed, most of the patients have symptoms in relation to cirrhosis of the liver. Spread metastases are not frequent and the extension to soft tissues is exceptional. We reported a 55 year old patient who had alcoholic cirrhosis and HCC with quickly development. The onset was a spinal cord compression due to soft tissues epidural metastases, seated at paravertebral zone. Plain radiographs and radionuclide bone scans were normal; diagnosis was achieved by magnetic resonance imaging and fine-needle aspiration cytology of the tumor. We have found no bibliographic reference on spinal cord compression due to soft tissues metastases from HCC. We want to point out the importance of including soft tissues metastases in differential diagnosis for radiculopathies with normal radiography and radionuclide scanning in patients at risk, considering also patients with hepatocellular carcinoma.
