Implementing the CFCM-ESI for Real Patient Cases
In this section, we present two real cases of patients who entered the ED in order to
illustrate the function of the CFCM-ESI for ED triage. Both cases involve elderly
patients.
Case 1
An 80 year-old male, accompanied by a relative, presented to the emergency depart-
ment with the chief complaint of altered mental status [48]. The patient's relative
stated that the patient woke up the day before very forgetful with subsequent im-
provement while the previous evening the patient had developed numbness to the
jaw. Also, that he has been very depressed since the death of a family member in
the past year. The patient denied experiencing pain. Triage vital signs were found
to be:
BP 138/78 mm Hg ,
HR 66 beats/min ,
RR 16 breaths/min ,
Temperature 97.8F (36.5C) ,
Oxygen saturation 97% .
Using a 5-level triage acuity scale he was assigned a Level 3-Acute triage acuity.
According to the source however, this patient, based on the minimal information
provided in the triage assessment, should have been assigned a Level 2 (Urgent)
triage acuity according to the criteria for ESI (Emergency Severity Index).
The competitive FCM-ESI was run using the initial factor concept values:
FC1=0
FC2=0
FC3=S
FC4=W
FC5=S
FC6=S
FC7=M
FC8=S
FC9=W
FC10=S
FC11=W FC12=W FC13=0
FC14=S
FC15=W
FC16=0
FC17=W FC18=W FC19=W FC20=0
FC21=0
FC22=0
The results are shown in Fig. 27.5 where the ESI acuity level assigned by the
CFCM-ESI is Level 2 since the output values of the ESI nodes were calculated
to be:
ESI 1 = 0.2181
ESI 2 = 0.7072
ESI 3 = 0.6726
ESI 4 = 0.1432
ESI 5 = 0.1131
