Case Narrative:
-
Chief Complaint
– Altered Mental Status
-
History
– Patient is an 82 year old female who presents from a nursing home
via EMS for evaluation of altered mental status and fever. Per
paramedics, the nursing home staff noted a fever of 102.2 and the
patient has not been as alert as she was 2 days ago. She has been a
resident there for two months while trying to rehabilitate from a
hip fracture.
-
Additional history given only if nursing home or husband is called
– Nurse states she usually takes care of the patient during the week
and last Friday she was doing well, but something happened over
the weekend.
– She still is not getting out of bed.
– She had a foley catheter placed recently.
– Her Primary Medical Doctor (PMD) is treating her with
amoxicillin.
– The patient has a son, but he only has been to the nursing home
once or twice to see his mother.
– Patient resuscitation status is DNI.
 The only way to obtain this information is to contact her
husband listed on the nursing home demographic sheet or
the nursing home personal. The DNR/ DNI sheet did not
arrive with the patient.

Skin – tinting, no cyanosis

 Large 10 cm sacral decubitus ulcer stage 4 with
surrounding erythema, yellowish-green base, and foul
sweet smell.
Scenario Branch Points
– The resident participant must identify the septic patient. This will
be evident through her general appearance, physical exam, and
vital signs.
– The etiology of her sepsis is obtained not only by labs (UTI /
pyelonephritis), but also by a thorough physical exam. Only if she
is rolled with they identify the infected decubitus ulcer, suspicious
for pseudomonas.
– Aggressive resuscitation should be initiated with IVF, antibiotics,
and vasopressors.
– Fluid resuscitation can be guided by a CVP through a central
venous line or by evaluating IVC compression with an ultrasound.
– Antibiotic coverage must be tailored to include methicillin resistant
Staphylococcus aureus, Pseudomonas, and urinary flora.
– The patient will require at least 4 liters of fluid resuscitation, 2
units of PRBCs, and vasopressors before vital signs, urinary
output, or perfusion will improve.
– The patient will appear to need mechanical ventilation, but this
should not be done. The resident needs to obtain the patient’s code
status, and this can only be done by contacting her husband or
nursing home.
– If the patient is intubated, her husband will spontaneously arrive in
the Emergency Department requesting she be taken off the
ventilator.
– The resident should consult both the Medical Intensivist and
Surgeon for evaluation and admission.
Instructors Notes:
-
Tips to Keep the Scenario Flowing
– The director should give the paramedic report
– The director should answer questions as if they were the patient
– Make the patient be very vague, altered and toxic appearing
– Do not give tips regarding the presence of a sacral decubitus ulcer.

Tips to Direct Actors
–
–
-
Nurses will be new grads and unfamiliar with management of
sepsis. They will need specific drug dosages and instructions for
what type of IV access, lines, etc…
The Patient’s Husband - You will be very distinct regarding the
patient’s DNI status if contacted over the phone. If not contacted
and the patient is intubated, you should let your disappointment be
known once you arrive to the Emergency Department. Request
that your mother’s breathing tube be removed.
Scenario Steps
–
–
-
The patient must not improve unless the appropriate amounts of
fluids are given.
The patient’s appearance, vitals and perfusion will not improve
with only 1-2 liters of IVF and vasopressors.
Allow the resident to intubate the patient if they so choose.
If intubated, the patient’s husband will arrive in the ED with
disapproval of the decision to intubate and request she be taken off
the ventilator.
Optimal Management Path
 Identify sepsis and likely etiology (UTI, pyelonephritis,
infected sacral decubitus ulcer)
 IVF Resuscitation guided by CVP (via central venous line
or IVC using U/S)
 Blood and Urine Cultures
 Tailored Antibiotics
 Contacting Family
 Respecting patient’s DNI status
Potential Errors Path
 Not recognizing sepsis
 Not obtaining cultures
 Not rolling the patient and identifying the sacral decubitus
ulcer likely infected with pseudomonas
 Under resuscitation with not enough IVF
 Starting vasopressors without completely resuscitating the
patient with IVF beforehand
 Not contacting family members
 Intubating the patient
