Undetected Sleep Apnea in the Postanesthesia Acute Care Unit
The primary aim is to determine whether patients with suspected OSAHS as predicted by the
STOP-BANG questionnaire will have an increased length of stay (LOS) in the postanesthesia
acute care unit (PACU) compared with those without suspected OSAHS.
The second aim will be to determine the LOS in patients with known sleep apnea by history.
This length of stay will be compared with LOS in patient with an affirmative response to the
STOP-BANG questionnaire to determine if prior knowledge of diagnosed sleep apnea will be
associated with a lower LOS than in patients with suspected OSA.
The third aim will be to characterize the adverse clinical outcomes (respiratory,
cardiovascular, and neurological) associated with suspected OSAHS in patients who respond
affirmatively to the STOP-BANG questionnaire and in those patients with known OSA. These data
(including number of desaturations, bradypnea, brady- or tachycardia, and use of reversal
agents) will be recorded by the PACU nursing staff. Unexpected admissions to the hospital and
transfers to the intensive care units will also be measured. These data will help identify
the most critical determinants of length of stay.

The study will retrospectively review the anesthetic record, including both the preoperative
assessment records and the PACU flow sheets. The study will be conducted in the
Anesthesiology Assessment Center. PACU. The STOP-BANG questionnaire is administered as part
of the standard of care during the preoperative assessment.
Anesthesia Assessment Center clinics assess approximately 500 patients a week, of which
approximately 25% are scheduled for ambulatory surgical procedures in the Mays clinic.
Patients are administered the STOP-BANG questionnaire as part of the standard of care while
in the perioperative center. This will be recorded on the Initial Anesthesia Assessment
Center Patient Record. This form is filled out by hand by the patients themselves and then
scanned into Clinic Station. The neck circumference portion of the Bang questionnaire is
assessed and recorded by the medical assistant with the use of a single use disposable paper
tape measure. The data are recorded along with basic demographic, historical, and
anthropometric data (including BMI) in a preoperative assessment record.
In order to satisfy the first specific aim, length of stay in minutes as determined by the
PACU nursing record will be documented. Nurses charting the LOS will not be specifically made
aware of the STOP-BANG status of the subjects. Length of stay is charted in the PACU nursing
forms electronically in PICIS and relayed to Clinic Station as part of the standard of care
for all patients admitted to the PACU.
In order to satisfy the third specific aim, patients enrolled in the study will be monitored
for secondary outcomes via chart review of the PACU nursing record and electronic medical
record. These outcomes are charted in the PACU nursing forms electronically in PCIS and
relayed to Clinic Station as standard of care in all patients in the PACU.
