Although Taipei City government has requested the emergency response hospitals to implement
Hospital Emergency Incident Command System (HEICS) since 2002, the
initial evaluation revealed inadequate results last year. After SARS endemics,
we re-evaluated the response plans provided by these hospitals to evaluate if the HEICS has
been implemented. Of the 53 plans, there were about 51 (96%) that
had predictable chain of management, and the average score was 79
points. As to accountability of position function, there were more
plans meeting with the criteria than last year (58% v 19%, P<0.01),
as the average score was (68+5 v 45+10, P<0.01). There were also more hospitals (n=31; 58% v 13%, P<0.01) containing flexible organizational
chart that allowed flexible response, improved documentation of
facility and common language to facilitate outside assistance. The
individual scores were also significantly higher than last year.
Twenty-four hospitals fulfilled the requirements of prioritized
response checklists, cost effective emergency planning within health
care corporations, and complete governmental requirements. The scores
were thus 64, 66 and 64 respectively. The average score was significantly
higher in tertiary center than in other hospitals (88+9 vs.
56+12, P<0.001). In summary, there is a trend that
the hospitals implemented HEICS into their response plans spontaneously
after SARS endemics. It may imply that HEICS can be a good model
for disaster response.

Introduction
|
|
|
|
It was well known
in recent years that the Hospital Emergency Incident Command System
(HEICS) has been developed to assist the operation of a medical
facility in a time of crisis.1 The main structure of the system
is a chain of command that incorporates four sections under the
overall leadership of an emergency incident commander. 1
The four sections including planning, finance, logistics, and operations,
have their specific leader assigned by the incident commander. The
leaders in turn designate directors and unit leaders of each department,
with each levels of specific staffs filling other crucial roles.
This structure limits the span of control of each manager in order
to distribute the work and also provides for a system of documenting
and reporting all emergency response activities. It is also proven
to lessen liability and promote the recovery of financial expenditures.
To our knowledge, HEICS does not take any specific type of disaster
as the essentials of the operation. In other words, it can be applied
to any kind of mass casualty under the concept of “general management
model”. It is then logical to consider the bioterrorism or an endemic
event as the scope of HEICS.
Taipei City government has begun to request the emergency response
hospitals to implement HEICS in their disaster response planning
since 2002. However, our past survey revealed that there are still
many engagements in training, understanding of HEICS and the overwhelming
idea of changing out an entire disaster plan in our systems. 2
Despite the efforts to educate the emergency response hospitals,
our initial evaluation still disclosed that most of the hospitals
did not understand completely the operation of HEICS. However, when
SARS made an endemic episode globally this year, Taiwan became one
of the prevalent areas. Most of the response hospitals adjusted
their response plans. It deserved us to re-evaluate their plans.
We therein retrospectively collected the SARS response plans from
these hospitals and examined if they were comparable with HEICS.

There were 53 emergency response
hospitals accounting for 20,160 beds in Taipei City in 2003. Of
these hospitals, seven were the tertiary care medical centers and
the remaining 46 secondary referral hospitals. We then evaluated
the SARS response plans from these hospitals retrospectively. We
reviewed all the plans under the guidelines of HEICS that concentrated
upon: predictable chain of management; accountability of position
function; flexible organizational chart; documentation of facility;
communication to facilitate outside assistance; prioritized response
checklists; cost-effective emergency planning within health care
institutes; governmental requirements as was the case with public
hospitals. For these 8 categories, there were about 5 to 7 items
to evaluate the adequacies of the plans. Four individual experts
evaluated the plans to determine the scoring. The final scores were
summed up and averaged 4 individual scores. The scoring was then
compared according to the different levels (or rankings) of these
hospitals.
The final results of evaluation were compared with the performance
last year. 2

Performances of SARS Response Plans Judged
by HEICS |
Of the 53 plans, there
were about 51 (96%) that had predictable chain of management, and
the average score was 79 points (P=NS v 78 points last
year). As to accountability of position function, there were more
plans that met with the criteria (n=31; 58% v 19%, P<0.01),
as the average score was (68+5 v 45+10, P<0.01). There
were also more hospitals (n=31; 58% v 13%, P<0.01) that
had flexible organizational chart that allows flexible response
to specific emergencies (average scores 68+13 v 40+3, P<0.01),
improved documentation of facility (64+10 v 40+6, P<0.01)
and also common language to facilitate outside assistance (60+6
v 48+8, P<0.05). Twenty-four hospitals (45.3%) have
provided prioritized response checklists, cost effective emergency
planning within health care corporations, and complete governmental
requirements (P<0.001 v 11.3% last year). The scores
were thus 64, 66 and 64 respectively. |

Comparisons among Different Rankings of
Hospitals |

We compared the performances of 7 tertiary-care medical
centers with another 46 secondary hospitals. The average score was
significantly higher in tertiary centers than in other hospitals (88+9
vs. 56+12, P<0.001). |

Discussion |
|
|
|
There has been a
trend that a hospital's emergency preparedness plan is undergone
under the guidance of HEICS. 1 The HEICS
plan for hospitals offers the benefits 1,3
such as predictable chain of management; accountability of position
function; flexible organizational chart allowing flexible response
to specific emergencies; improved documentation of facility; common
language to facilitate outside assistance; prioritized response
checklists; cost effective emergency planning within health care
corporations, and governmental requirements in public hospitals.
Under the structure of the ICS, emergency response plans share many
organizational characteristics with other ICS based plans. The common
language shared between plans is a great benefit and can bind hospitals
and non-hospitals together in times of crisis.
Our past survey revealed that most of the hospitals in Taipei still
did not make full use of the HEICS. 2
The possible reasons for the hesitancy for a conversion may include
time, cost and lack of internal desire. Sometimes the real reason
is lack of understanding of HEICS and the overwhelming idea of changing
out an entire disaster plan. All of these concerns are valid. However,
all facilities need to examine the real attributes and benefits
of an Incident Command System-based plan. There are distinctive
advantages to the entire disaster medical response community when
all participants operate in a similar, predictable fashion.
There has been a major global outbreak of SARS. 4-8
Although the confirmatory tests such as polymerase chain reaction
and measurements of coronavirus antibody have been undergone in
many laboratories, 9 they still cannot
provide instant and correct information for clinicians at the first
moment. The WHO criteria may help screen the suspected and probable
cases, 8 but the low specificity may
indicate the lacking of cost-effectiveness in an endemic area. Most
of the emergency response hospitals agreed that SARS is a kind of
disaster and re-considered the response plan for such a disaster.
After SARS, most of the hospital staffs believe that disasters are
neither merely large-scale emergencies, and nor is the disaster
response an expansion of the routine emergency response, supplemented
by the mobilization of extra personnel, supplemented by the mobilization
of extra personnel, supplies, accommodations, and equipment. 9-11
Most of the past studies demonstrated that the disasters had unique
problems that require different strategies, both quantitatively
and qualitatively.12-14 The disaster response involves variable
destruction of communication system, working with different people,
solving different problems, and using different resources than those
for routine emergencies, 3,12-14
so it has to be flexible in total operation but constant in role
playing. As we mentioned before, the low frequency of devastating
disasters always poses a problem for hospital planners, because
few planners have had enough disaster experience. There is still
no nationally institutionalized process for data collecting, analyzing,
and generalizing the education based upon past experiences. Global
warning or alerting system may be a good start.
Because of the impact of SARS, many hospitals have been confronted
with the problem of possible total isolation. The response plans
of isolation, evacuation, relocation, and reception were thereof
seriously considered by there hospitals during the period. Other
tasks such as resource sharing, widespread search and rescue, triage,
patient transport that efficiently utilizes area hospital assets,
dealing with the press, and overall coordination of the responsehave
already mentioned in previous guidelines of HEICS. 1,2
Most of the hospital administrators also agreed that HEICS could
afford not only what were expected but also what were unexpected
because of its underlying “general management principle”. 11
In contrast, a traditional written plan can be an illusion of preparedness
if other requirements are neglected. 3,6,9
It was so-called “paper plan syndrome”. Reasonable and valid
assumptions about the trends and prevalence of the disasters, inter-organizational
perspective, 2,15
and the provision of resources 12 become
the essence of the plans. Repeated training and drills can make
each staff familiar with the system, 16
and operate accordingly from his heart. All of the staffs have to
be engaged in the modification and operation in every stage of the
disasters in the practical, realistic, and legitimate way. 17,18
In conclusion, although SARS brought us a devastating disaster,
it still made the hospitals implemented the HEICS spontaneously
into their disaster response plans. The good beginning should be
considered a significant advance in disaster preparedness.
