facility and specific inpatient location, the NHSN user must take into
account all such days, including any days spent in an inpatient location as
an “observation” patient before being officially admitted as an inpatient to
the facility, as these days contribute to exposure risk. Therefore, all such
days are included in the counts of admissions and patient days for the
facility and specific location, and facility and admission dates must be
moved back to the first day spent in the inpatient location.
Risk Factors:

assigned when the PNEU was identified. If the PNEU develops in a
patient within 48 hours of transfer from a location, indicate the
transferring location, not the current location of the patient.
Required. Enter date patient admitted to facility using this format:
MM/DD/YYYY. An NHSN Inpatient is defined as a patient whose
date of admission to the healthcare facility and the date of discharge are
different calendar days. When determining a patient’s admission
dates to both the facility and specific inpatient location, the NHSN
user must take into account all such days, including any days spent
in an inpatient location as an “observation” patient before being
officially admitted as an inpatient to the facility, as these days
contribute to exposure risk. Therefore, all such days are included in
the counts of admissions and patient days for the facility and
specific location, and facility and admission dates must be moved
back to the first day spent in the inpatient location.

Risk Factors
Ventilator Required. Check Y if the patient with PNEU had a device to assist
or control respiration continuously through a tracheostomy or by
endotracheal intubation, inclusive of the weaning period, within the

anesthesia is defined as the administration of drugs or
gases that enter the general circulation and affect the
central nervous system to render the patient pain free,
amnesic, unconscious, and often paralyzed with relaxed
muscles.
ASA class: Conditionally Required. Required for Inpatient
procedures only. Check numeric ASA classification at
the time of the operative procedure.
Emergency: Required. Check Y if this operative procedure was a
nonelective, unscheduled operative procedure, otherwise
check N. Emergency operative procedures are those that
do not allow for the standard immediate preoperative
preparation normally done within the facility for a
scheduled operation (e.g., stable vital signs, adequate
antiseptic skin preparation, colon decontamination in
advance of colon surgery, etc.).

Specimen Source

Required. Enter the specific anatomic site from which the specimen was
taken using the source description that is most accurate from the available
choices (e.g., bile specimen, specimen from brain, etc.)
Date Admitted to Facility Conditionally required. Enter the date the patient was admitted to facility
using this format: MM/DD/YYYY. If the LabID Event was reported from
an outpatient location, leave this blank. An NHSN Inpatient is defined as
a patient whose date of admission to the healthcare facility and the date of
discharge are different calendar days. When determining a patient’s

admission dates to both the facility and specific inpatient location, the
NHSN user must take into account all such days, including any days
spent in an inpatient location as an “observation” patient before being
officially admitted as an inpatient to the facility, as these days
contribute to exposure risk. Therefore, all such days are included in
the counts of admissions and patient days for the facility and specific
location, and facility and admission dates must be moved back to the
first day spent in the inpatient location.
Location

Date Admitted to
Location

Conditionally required. Enter the patient care area where the patient was
assigned when the laboratory-identified MDRO or C. difficile event
specimen was collected (i.e., the NHSN “transfer rule” does not apply for
LabID events). Special Case: If a specimen collected in the emergency
department is positive for an MDRO or CDI, and the patient it is collected
from is admitted to the facility on the SAME date into a location that is
monitoring LabID Events for the identified MDRO or CDI, then that
specimen can be reported as the first specimen for the patient in that
admitting inpatient location for the month. If the facility is also monitoring
LabID Events for the same MDRO or CDI in the emergency department,
then the same specimen for the patient would also be reported a second time
for that outpatient location.
Conditionally required. Enter the date the patient was admitted to the patient
care area where laboratory-identified monitoring is being performed and
where the specimen was collected from the patient. Any days spent in an

inpatient location, whether as an officially admitted patient or as an
“observation” patient, contribute to exposure risk. An NHSN
Inpatient is defined as a patient whose date of admission to the
healthcare facility and the date of discharge are different calendar days.
Therefore, all such days are included in the counts of patient days for
the facility and specific location. Special Emergency Department Cases:

facility and specific inpatient location, the NHSN user must take into
account all such days, including any days spent in an inpatient location
as an “observation” patient before being officially admitted as an
inpatient to the facility, as these days contribute to exposure risk.
Therefore, all such days are included in the counts of admissions and
patient days for the facility and specific location, and facility and
admission dates must be moved back to the first day spent in the
inpatient location.
Location

Required. Enter the nursing care area where the patient was assigned when the
MDRO or C. difficile infection (CDI) was acquired. If the MDRO or CDI
developed in a patient within 48 hours of discharge from a location, indicate
the discharging location, not the current location of the patient.
