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

Health system preparedness for bioterrorism: bringing the tabletop to the hospital

OBJECTIVE

To evaluate the acceptance and usefulness of a hospital-based tabletop bioterrorism exercise.

DESIGN

A descriptive study of responses to a smallpox scenario delivered as a tabletop exercise in three modules.

SETTING

A large, multi-institutional urban health system.

PARTICIPANTS

Healthcare workers representing 16 hospital departments.

RESULTS

Thirty-nine (78%) of 50 invited employees from 4 hospitals participated. Key responses highlighted the importance of pre-event planning in intra-departmental communication, identification of resources for the dependents of healthcare workers, clarification of the chain of command within the hospital, establishment of a link to key governmental agencies, and advanced identification of negative pressure rooms for cohorting large numbers of patients. Almost one-fourth of the participants described their hospital department as poorly prepared for a bioterrorism event of moderate size. At the conclusion of the tabletop, 79% of the participants stated that the exercise had increased their knowledge of preplanning activities. Seventy-nine percent of all participants, 94% of physicians and nurses, and 95% of participants from non-university hospitals ranked the exercise as extremely or very useful. The exercise was completed in 3 1/2 hours and its total direct cost (excluding lost time from work) was 225 dollars (U.S.).

CONCLUSIONS

Tabletop exercises are a feasible, well-accepted modality for hospital bioterrorism preparedness training. Hospital employees, including physicians and nurses, rank this method as highly useful for guiding preplanning activities. Infection control staff and hospital epidemiologists should play a lead role in hospital preparedness activities. Further assessment of the optimal duration, type, and frequency of tabletop exercises is needed.

Disaster preparation and management for the intensive care unit

The purpose of this report is to provide information regarding preparation for disaster management from the perspective of ICU physicians. Both a framework toward ICU preparation for disaster management and a guide to the relevant literature are presented. Our objective is to show that the understanding of disaster preparedness on multiple levels, including government, hospital, ICU, and clinician, may lead to optimal management in a disaster.

Modeling the public health response to bioterrorism: using discrete event simulation to design antibiotic distribution centers

BACKGROUND

Post-exposure prophylaxis is a critical component of the public health response to bioterrorism. Computer simulation modeling may assist in designing antibiotic distribution centers for this task.

METHODS

The authors used discrete event simulation modeling to determine staffing levels for entry screening, triage, medical evaluation, and drug dispensing stations in a hypothetical antibiotic distribution center operating in low, medium, and high disease prevalence bioterrorism response scenarios. Patient arrival rates and processing times were based on prior mass prophylaxis campaigns. Multiple sensitivity analyses examined the relationship between average staff utilization rate (UR) (i.e., percentage of time occupied in patient contact) and capacity of the model to handle surge arrivals.

RESULTS

Distribution center operation required from 93 staff for the low-prevalence scenario to 111 staff for the high-prevalence scenario to process approximately 1000 people per hour within the baseline model assumptions. Excess capacity to process surge arrivals approximated (1-UR) for triage staffing.

CONCLUSIONS

Discrete event simulation modeling is a useful tool in developing the public health infrastructure for bioterrorism response. Live exercises to validate the assumptions and outcomes presented here may improve preparedness to respond to bioterrorism.

The World Trade Center attack. Is critical care prepared for terrorism?

This commentary on the World Trade Center attack is written from the perspective of a New York City critical care service, with a long history of activity in disaster management, which is located at the Montefiore Medical Center/Albert Einstein College of Medicine. The paper describes some of the local concerns of the service in the first hours, the reality of dispersal of victims throughout the New York City hospital system, and some of the resources made available and their utilization. In general, the US Critical Care Medicine System receives massive resources in terms of gross national product expenditure when compared with other developed countries. A large capacity is subsequently in place to provide care to critically ill patients resulting from manmade as well as natural disasters. It was the nature of the World Trade Center attack in terms of the ratio of injured survivors to dead victims that did not allow the full capacity and capability of the system to engage.
