Out-of-Center Sleep Testing, or OCST, is an at home sleep assessment indicated for
OCST is contraindicated for the following:
The patient must have a face-to-face clinical evaluation by the treating physician prior to the sleep test to assess the patient for Obstructive Sleep Apnea. In addition to the physical examination, there are several validated screening questionnaires available to determine if a patient is a candidate for OCST. Validated screens include the Epworth Sleepiness Scale, the Berlin Questionnaire, and the Watermark ARES Risk Evaluation.
The testing is performed using an unattended Type III portable monitoring sleep study device which will monitor your patient for Obstructive Sleep Apnea (OSA). Parameters that are measured include simultaneous airflow, respiratory events, pulse rate, oxygen saturation, head position/movement, arousal indicators, snoring, sleep/wake, REM/NREM, apnea/hypopnea index, and sleep time.
The precertification process should begin the day the patient is scheduled for their OCST or after a denial for in-lab diagnostic testing is received. Patients may be scheduled for testing quickly for convenience.
Our Type III testing devices are approved for the following procedure codes
Patients ordered and approved for OCST will be scheduled to come into the Sleep Disorders Center at Community Hospital Anderson to be educated on the application and use of the device by a Registered Polysomnogram sleep technologist. The patient applies the equipment later that evening and undergoes a sleep study in the comfort of their home. After the ordered number of nights (1-3 nights) has been recorded and the patient returns the device to the Sleep Disorders Center, the data is downloaded for scoring, reporting, and interpreted by a board certified sleep specialist. Our sleep specialist will then recommend and order any additional testing or treatment.
