Updated Interim Guidance: Pre-Hospital Emergency Medical Care and Ground
Transport of Suspected Severe Acute Respiratory Syndrome Patients
April 11, 2003, 12:30 PM ET |
Introduction
The current outbreak of Severe Acute Respiratory Syndrome (SARS)
has included reports of cases in Southeast Asia, Europe, and North America; and
has required ground emergency medical services (EMS) to move patients to medical
facilities for further assessment and care. This guidance is intended to assist
Emergency Medical Services (EMS) providers to manage suspected SARS patients
while ensuring the safety of patients and transport personnel. These interim
recommendations are based on standard infection control practices and available
epidemiologic information regarding the transmission of SARS.
Currently recommended infection
control measures for hospitalized patients with SARS include Standard
precautions (with eye protection to prevent droplet exposure), plus Contact and
Airborne precautions. Respiratory protection using respirators providing at
least 95% filtering efficiency (e.g., N-95) with appropriate
fit-testing is recommended. The following guidelines are adapted from these
recommendations.
I.
Emergency medical ground transport of SARS patients, general considerations
 |
Suspected SARS
patients should be transported using the minimum number of EMS personnel and
without non-SARS patients or passengers in the vehicle. |
 |
Receiving
facilities must be notified prior to arrival of suspected SARS patients to
facilitate preparation of appropriate infection control procedures and
facilities. |
 |
Concerns
regarding movement of possible SARS patients in the United States should be
discussed with appropriate local, state and federal health authorities,
including the Centers for Disease Control and Prevention (CDC) (24 hour
response number: (770) 488-7100). |
II.
Infection Control
General
 |
In addition to
respiratory droplet and possible airborne spread, SARS may be transmitted if
residual infectious particles on environmental surfaces are brought into
direct contact with the eyes, nose or mouth, e.g., by unwashed hands.
Therefore, hand hygiene is of
primary importance for all personnel working with possible SARS patients.
|
 |
Protective
equipment should be used throughout transport of a suspected SARS patient.
|
 |
Personal
activities (including: eating, drinking, application of cosmetics, and
handling of contact lenses) should not be performed during patient transport. |
Protective equipment and procedures
 |
Disposable,
non-sterile gloves must be worn for all patient contact. |
 |
Gloves should be
removed and discarded in biohazard bags after patient care is completed (e.g.,
between patients) or when soiled or damaged. |
 |
Hands must be
washed or disinfected with a waterless hand sanitizer immediately after
removal of gloves. |
 |
Disposable
fluid-resistant gowns should be worn for all direct patient care. |
 |
Gowns should be
removed and discarded in biohazard bags after patient care is completed or
when soiled or damaged. |
 |
Eye-protection
must be worn in the patient-care compartment and when working within 6 feet of
the patient. Corrective eyeglasses alone are not appropriate protection.
|
 |
N-95 (or greater)
respirators should be worn by personnel in the patient-care compartment during
transport of a suspected SARS patient; personnel wearing respirators should be
fit tested. |
 |
The door/window
between driver and patient compartments should be closed before a suspected
SARS patient is brought onboard. N-95 (or greater) respirators should be worn
by the driver if the driver's compartment is open to the patient-care
compartment. Drivers that provide direct patient care (including moving
patients on stretchers) should wear a disposable gown, eye-protection, and
gloves as described above during patient-care activities. Gowns and gloves are
not required for personnel whose duties are strictly limited to driving.
|
 |
Vehicles that
have separate driver and patient compartments and can provide separate
ventilation to these areas are preferred for transport of possible SARS
patients. If a vehicle without separate compartments and ventilation must be
used, the outside air vents in the driver compartment should be open, and the
rear exhaust ventilation fans should be turned on at the highest setting
during transport of SARS patients to provide relative negative pressure in the
patient care compartment. |
 |
Oxygen delivery
with non-rebreather facemasks may be used for patient oxygen support during
transport. |
 |
The patient may
wear a paper surgical mask to reduce droplet production, if tolerated.
|
 |
Positive pressure
ventilation should be performed using a resuscitation bag-valve mask. If
available, units equipped for HEPA or equivalent filtration of expired air
should be used. |
 |
Cough-generating
procedures should be avoided during pre-hospital care (e.g., nebulizer
treatments). |
III.
Mechanically Ventilated Patients
 |
EMS organizations
should consult their ventilator equipment manufacturer to confirm appropriate
filtration capability and the effect of filtration on positive pressure
ventilation. |
 |
Mechanical
ventilators for SARS-patient transport should provide HEPA or equivalent
filtration of airflow exhaust. |
IV.
Clinical Specimens
 |
Standard
precautions must be used when collecting and transporting clinical specimens.
|
 |
Clinical
specimens should be labeled with appropriate patient information and placed in
a clean self-sealing bag for storage and transport. |
V. Waste
disposal
 |
Dry solid waste,
e.g., used gloves, dressings, etc., should be collected in biohazard bags for
disposal as regulated medical waste in accordance with local requirements at
the destination hospital. |
 |
Waste that is
saturated with blood, body fluids, or excreta should be collected in
leak-proof biohazard bags or containers for disposal as regulated medical
waste in accordance with local requirements at the destination hospital.
|
 |
Sharp items such
as used needles or scalpel blades should be collected in puncture resistant
sharps containers for disposal as regulated medical waste in accordance with
local requirements at the destination hospital. |
 |
Suctioned fluids
and secretions should be stored in sealed containers for disposal as regulated
medical waste in accordance with local requirements at the destination
hospital. Handling that might create splashes or aerosols during transport
should be avoided. |
 |
Suction devices
should be fitted with in-line HEPA or equivalent filters in accordance with
manufacturer's recommendations. |
VI.
Cleaning and Disinfection after transporting a possible SARS patient
 |
Compressed air
that might re-aerosolize infectious material should not be used for cleaning
the vehicle or reusable equipment. |
 |
Non-patient-care
areas of the vehicle should be cleaned and maintained according to vehicle
manufacturer's recommendations. |
 |
Personnel
performing cleaning should wear non-sterile gloves, disposable gowns and
eye-protection while cleaning the patient-care compartment. |
 |
Patient-care
compartments (including stretchers, railings, medical equipment, control
panels, and adjacent flooring, walls and work surfaces likely to be directly
contaminated during care) should be cleaned using an EPA-registered hospital
disinfectant in accordance with manufacturer's recommendations. |
 |
Spills of body
fluids during transport should be cleaned by placing absorbent material over
the spill and collecting the used cleaning material in a biohazard bag. The
area of the spill should be cleaned using an EPA-registered hospital
disinfectant. Cleaning personnel should be notified of the spill location and
initial clean-up performed. |
 |
Contaminated
reusable patient care equipment should be cleaned and disinfected promptly
after use and before returning to service. |
 |
Personnel should
wear non-sterile gloves, disposable gowns and face shields while cleaning
reusable equipment. |
 |
Reusable
equipment should be cleaned and disinfected according to manufacturer's
instructions. |
VII.
Follow-up of EMS Personnel who Transport suspected SARS Patients
 |
Personnel who
have transported a suspected SARS patient and develop symptoms of SARS within
the 10 day post-exposure period should be directed to seek medical evaluation
and should be reported to the state health department and to the CDC at the
number listed above. |
 |
Personnel may
continue working during the 10 day post-exposure period if they have no
symptoms of fever or respiratory illness. |
