BACKGROUND: Hospitals would play a critical role in a weapon of mass destruction (WMD) event. The purpose of this study is to assess preparedness for mass casualty events in short-term and long-term hospitals in Kentucky. METHODS: All short-term and long-term hospitals in Kentucky were surveyed using an instrument based on the Mass Casualty Disaster Plan Checklist and a brief supplemental bioterrorism preparedness questionnaire based on a checklist developed for the Agency for Healthcare Research and Quality. RESULTS: Responses were received from 116 of the 118 (98%) hospitals surveyed. Hospitals reported surge capacity equal to 27% of licensed beds, and virtually all respondents were engaged in planning for weapons of mass destruction events. However, advanced planning and preparation were less common. Large regional differences were observed, especially in the area of pharmaceutical planning. Preparedness planning in general and pharmaceutical management planning in particular were more advanced in counties participating in the Metropolitan Medical Response System Program (MMRS). CONCLUSIONS: Hospital mass casualty preparedness efforts were in an early stage of development at the time of this survey, and some critical capabilities, such as isolation, decontamination, and syndromic surveillance were clearly underdeveloped. Preparedness planning was more advanced among hospitals located in MMRS counties.

In response to the terrorist attacks of September 11, 2001 (9/11) and the release of anthrax through the mail in the following weeks, the federal government provided $135 million to the states in fiscal year 2003 through the Bioterrorism Hospital Preparedness Program. 1 States were required to assess hospital preparedness and develop regional response plans to receive the bulk of these funds. 2 In Kentucky, the total allocation was approximately $1.8 million, and the Kentucky Department for Public Health contracted with the Kentucky Hospital Association (KHA) to conduct the assessment. 3 The KHA established a bioterrorism task force comprising hospital executives, infection control practitioners, emergency planners, and KHA staff to survey hospitals in the state. This task force approved the survey methodology and provided oversight for the study.

After considering several checklist type instruments, the task force selected the Mass Casualty Disaster Plan Checklist: A Template for Healthcare Facilities, developed by the Association of Professionals in Infection Control and Epidemiology (APIC) and the Center for the Study of Bioterrorism and Emerging Infections, 4 as the basis for the survey instrument. This paper reports findings from the KHA survey.

The danger of terrorism involving weapons of mass destruction (WMD) was recognized well before 9/11. The federal government increased support for preparedness in response to Presidential Decision Directive 39, issued in 1995, and the Defense Against Weapons of Mass Destruction Act of 1996, which included funds to improve planning, training, and equipment for local emergency response agencies. 5, 6 The federal government also funded the Metropolitan Medical Response System (MMRS), which supports planning, training, and equipment purchases to improve hospital and health system preparedness 6 and implemented a number of programs to strengthen the public health system.

The critical role of hospitals in any WMD event is widely recognized. Macintyre et al cited prompt recognition of the incident, staff and facility protection, patient decontamination and triage, medical therapy, and coordination with external emergency response and public health agencies as key elements of health care facility response plans. 7 The American Hospital Association (AHA) offered broad recommendations for hospital and community-wide preparedness. 8 More detailed recommendations for dealing with bioterrorism were developed jointly by the APIC Bioterrorism Task Force and the Centers for Disease Control and Prevention (CDC) Hospital Infections Program Bioterrorism Working Group, 9 and, effective on January 1, 2001, the Joint Commission for the Accreditation of Healthcare Organizations (JCAHO) required hospitals to have emergency management plans based on a hazard vulnerability analysis. However, the limited research evidence available prior to 9/11 suggested that hospitals were ill prepared to respond to casualties resulting from exposure to hazardous materials or radiation. [10] [11] [12] [13] [14] [15] This study assesses the preparedness of Kentucky hospitals to respond to bioterrorism and other mass casualty events.

The Mass Casualty Disaster Plan Checklist was modified in 2 ways to convert it into a survey instrument. First, some items on the checklist asked for a single answer to questions that contained 2 or more parts. These items were separated, unless the multiple parts were so closely related that a single response was appropriate. Second, some items of specific interest to the KHA task force were added (eg, respondents were asked how much their facility had spent on preparedness since 9/11). The final instrument was 14 pages long, with 252 items.

In July 2002, the questionnaire along with a cover letter was mailed to chief executive officers (CEOs) of all 118 short-term and long-term hospitals in Kentucky. The CEOs were asked to oversee completion of the survey. In practice, most CEOs assigned completion of the survey to staff members responsible for emergency planning and/or infection control, and input was typically obtained from several staff members. The survey was also available on the KHA Web site, and a few respondents completed it electronically.

In August 2002, the Agency for Healthcare Research and Quality (AHRQ) released a needs survey for hospitals to use as a checklist for assessing their capacity to handle victims of bioterrorist attacks and the adequacy of their emergency plans. 16 Because the AHRQ instrument focused on bioterrorism, the area of greatest concern to state officials, the KHA task force mailed a brief supplemental survey (3 pages, 20 questions) using items selected from the AHRQ instrument in September 2002.

Repeated calls were made by KHA staff to hospitals that did not respond to the surveys. Clarification and corrections were also made via telephone. In total, the survey process extended from July 2002 to February 2003.

One hundred sixteen hospitals and hospital systems (98%) responded to at least 1 survey. One hundred eight (92%) responded to both surveys; 3 responded to the first survey only, and 5 responded to the supplemental survey only. Responding hospitals accounted for all but 325 of Kentucky's 18,403 licensed hospital beds (98%). Hospital responses were aggregated for the state as a whole and for each of 14 multicounty emergency management areas (EMAs). Twelve of the EMAs had 100% response rates, and the lowest EMA response rate was 86%.

States were directed by the CDC to prepare regional response plans based on the assumption that resources to treat 500 casualties should be available. No guidance was provided regarding how many of the 500 casualties might require inpatient care. Statewide, hospitals reported the ability to surge 4881 beds or 27% of all licensed beds in the state. One hundred thirty-two surge beds (3%) were reported by long-term hospitals. Based on the assumption that 25% of casualties would require inpatient treatment, all 14 EMAs met the 500 casualty planning standard. However, when it was assumed that half of the casualties would require hospital admission, 6 rural EMAs did not have adequate surge beds. Respondents reported a total of 594 isolation beds and 937 adult, 193 pediatric, and 214 neonate ventilators. Only hospitals in the Louisville area reported operating at full bed capacity more than 25% of the time.

Virtually all hospitals (99%) had disaster plans and disaster planning committees (95%). More than 9 out of 10 reported collaborative relationships with emergency medical services (96%), emergency management agencies (94%), law enforcement agencies (95%), fire departments (95%), and health departments (92%). Almost all respondents (96%) reported that disaster plans were widely distributed and readily available throughout the facility. Eighty-three percent reported that the board and medical staff had reviewed the plan, and 73% reported that disaster plans addressed weapons of mass destruction incidents (defined as biologic, nuclear, incendiary, chemical, explosive and/ or radiologic on the survey instrument). Almost all (96%) reported conducting annual disaster exercises and conducting a formal critique of the exercise, which is shared with all key participants (90%).

More detailed questions concerning planning and preparation activities revealed mixed results. The vast majority of respondents reported that emergency plans addressed basic activities, such as designating an incident commander (90%), assigning responsibility for recalling off-duty staff (91%), and specifying the location of the hospital disaster control command center (90%). However, fewer reported plans that addressed more detailed activities, such as specifying which areas to close if staffing shortages occur (26%), specifying how volunteers were to be incorporated and managed (35%), and describing how to manage vehicles and personnel that converge on the facility (12%). Seventy-eight percent reported having the ability to lock down the facility, but only 56% had tested the lock down procedures.

Six sections of the primary survey had sufficiently high internal consistency and intercorrelation among items (Cronbach's a>0.7) to serve as composite measures of the variables of interest. For these sections (general response capability, ability to handle and control external traffic flow, preparation to deal with the news media, preparation to receive casualties and victims, preparation to deal with being out of communication or cut off from resources, and preparation to manage pharmaceuticals), a single index score, ranging from 0 to 1.0, was calculated for each EMA. Lower scores suggest that hospitals are less prepared to respond in a particular area. Table 1 displays median scores for each EMA and the median score for the state as a whole. For each composite measure, there was considerable variation across EMAs, although, as a group, hospitals reported a reasonable level of preparedness planning in all areas except pharmaceutical management. Hospitals were generally well prepared to receive casualties and conduct activities such as triage and treat, admit, or transfer multiple casualties on short notice, but pharmaceutical planning, which could be of vital importance in a bioterrorism event, was less advanced.

Only 43% of respondents reported that the pharmaceutical allocation plan provided for prophylaxis of caregiving staff, and even fewer reported planning for prophylaxis of first responders (34%) and caregiver's family members (20%). Thirty-two percent of respondents reported participating in a community or regional pharmaceutical stockpile. Thirty-eight percent reported emergency plans that addressed stockpiling antibiotics and supplies, and only 25% maintained a separate cache of antibiotics to treat staff in the event of a bioterrorist incident. Higher levels of pharmaceutical planning were observed in EMAs 6 and 13, which include Kentucky's 2 MMRS regions.

Most respondents reported that their medical staff members have access to information for treating victims of biologic (82%), chemical (77%), nuclear (67%), radiologic (69%), and major burn (73%) exposures. Sixty-three percent reported having radiation detection instruments, but only half reported having Surveillance capability is essential for detecting a covert bioterrorism event when the first indication of an attack may be patients presenting with influenzalike illness at hospital emergency departments, primary care physician practices, and clinics. 17, 18 Table 2 displays surveillance related responses from both surveys. More than half (56%) of respondents had electronic database systems that track patient's presenting problems. Of these, only 28% tracked influenza-like illness, and only 1 in 5 tracked increased antibiotic prescription rates.

Questions added to the primary survey by the KHA task force asked about hospital participation in regional bioterrorism response planning and changes initiated after 9/11. Half of all respondents reported participating in regional response plans. Among participants, about one quarter (24%) reported regional response plans addressing quarantine, and 39% reported plans addressing patient isolation.

Respondents reported updating disaster plans (81%), implementing additional training (66%), and purchasing new equipment (38%) since 9/11. Overall, respondents reported spending almost $1.7 million to increase preparedness in response to the terrorist attacks. When asked to identify their 3 highest priority needs if external funds became available, respondents listed almost $18.5 million in needed investments, primarily for training and equipment.

The Metropolitan Medical Response System (MMRS) of the US Department of Health and Human Services, which became operational in 1997, provides funds to major US cities to help them develop plans for responding to the health and medical consequences of a terrorist attack with chemical, biologic, or radiologic agents. 7 In fiscal year 2000, Louisville-Jefferson County and Lexington-Fayette County received MMRS contracts. To evaluate the impact of the MMRS program, responses from hospitals in Jefferson and Fayette Counties were compared with responses from hospitals in all other counties.

The Louisville and Lexington areas contain most of the state's large, tertiary care hospitals and both of its academic medical centers; thus, it was not surprising that hospitals in these areas reported more beds, larger pharmaceutical inventories, and more equipment, such as ventilators. They also reported greater laboratory capability to rule out potential bioterrorism agents. However, hospitals in Fayette and Jefferson Counties evidenced superior readiness in other areas that may be attributable to the MMRS program. Table 3 displays preparedness activities that were significantly more common among hospitals located in Fayette and Jefferson counties. Pharmaceutical planning was considerably more advanced in the MMRS counties. Hospitals in these counties were more likely to have dedicated decontamination facilities and to have conducted a disaster exercise using the decontamination facility. Agreements with other health care facilities to accept patients were more likely to be in place, and, as expected, regional planning was more advanced in the MMRS counties. Mean scores on the 6 composite measures were compared for hospitals in Fayette and Jefferson counties and facilities in all other counties. Hospitals in the MMRS counties scored significantly higher on the measures for pharmaceutical management (P < .001) and preparation for being out of communication or cut off from resources (P < .001).

The Mass Casualty Disaster Plan Checklist formed the basis for a useful instrument to assess hospital preparedness for WMD events. Results from the KHA surveys were used to develop regional hospital preparedness plans in Kentucky.

Large regional differences in hospital preparedness were observed across EMAs, with areas containing MMRS counties generally reporting more advanced levels of preparedness. Overall, the results suggest that much work remains to be done. Hospital WMD preparedness planning and coordination on a community or regional basis were in early stages of development at the time of this survey, and some critical hospital response capabilities, such as isolation, decontamination, and syndromic surveillance were clearly underdeveloped. These results are generally consistent with those of a national survey of 2021 short-term, nonfederal, general hospitals in metropolitan statistical areas conducted by the US General Accounting Office (GAO) between May and September 2002. The GAO found that most hospitals reported participating in basic planning and coordination activities for bioterrorism response, but many lacked the medical equipment to handle the number of patients that would likely result from a bioterrorist incident. 2 The MMRS program appears to be producing positive results as evidenced by the comparison of MMRS and non-MMRS counties in Kentucky. Most encouragingly, hospitals in MMRS counties reported more advanced pharmaceutical planning and preparedness, an area of critical importance in a bioterrorism event. However, the need for greater support for preparedness efforts in non-MMRS counties was evident in the large variations across EMAs and low scores on the composite measure of pharmaceutical planning.

There are several limitations to this study. First, the results cannot be generalized nationally because only hospitals in Kentucky participated. Second, the 2 surveys extended over 7 months at a time when hospitals were busily engaged in preparedness activities. Thus, it seems likely that early respondents continued to improve during the study period, and these improvements are not reflected in the results. However, much of the delay was caused by the need to clarify responses to questions in the supplemental survey, and the GAO survey also extended over a prolonged time period (4 months). 2 In addition, repeated calls from KHA staff resulted in a remarkably high response rate, although this process extended the duration of the survey. Third, Kentucky hospitals have continued to improve preparedness and response capabilities since this survey was completed. It is likely that hospitals are better prepared today in a number of areas, both because of increased investment and training related to bioterrorism readiness and in response to concerns raised by the outbreak of Severe Acute Respiratory Syndrome (SARS). Almost $1.8 million in federal funds have been provided to hospitals in the Commonwealth, and some hospitals purchased decontamination equipment and PPE with these funds. However, Kentucky hospitals had already spent almost $1.7 million of their own revenues to improve preparedness, and respondents identified more than $18 million in high priority needs. Thus, in Kentucky as elsewhere, the burden of preparing for catastrophic terrorism is largely an unfunded mandate for hospitals.

Finally, the finding that the MMRS program has had a favorable impact on hospital preparedness should be viewed as suggestive. The Institute of Medicine has recommended a comprehensive evaluation process for this program and noted several limitations of checklisttype questionnaires for evaluating complex programs, such as the MMRS. 7 Overall, the surveys described above provided a valuable input to regional and state-level preparedness planning. Comments from hospital CEOs suggest that responding to the survey based on the Mass Casualty Disaster Plan Checklist provided a useful educational experience for them and their staff, as well as helping improve emergency plans. As preparedness efforts continue, these or similar instruments could be administered periodically to assess the progress of hospital preparedness planning.
