Because the data is compressible and easily transferable, sleep studies may be sent from a sleep center or laboratory to a sleep tech in a different part of the world. The sleep study data is sent and reviewed by a sleep technologist (RPSGT or RST) and a sleep doctor. They are usually contracted for outsource sleep center services.
About the Sleep Study Scoring service Data
The data in a typical sleep study includes electroencephalogram for brain waves (EEG), electrooculogram for eye movements (EOG), electromyogram for muscle activity (EMG), electrocardiogram – for heart (EKG), snore sounds, airflow, respiratory effort movements, and oxygenation from an oxymetry probe on a finger. Often audio and video is collected as well.
There are a few professional sleep physician and technologist services that specialize in the outsource interpretation and sleep scoring of sleep studies.
After this data is collected on a patient, the data is reviewed page-by-page by a technologist who will score, or tabulate, all of this data into organized packets of clinical information.
After sleep study scoring is completed by the sleep tech, it will be sent to a sleep physician who will re-review this data and scored tech report and issue an interpretation of the sleep study, and often recommendations.
The sleep physician’s report will then be sent back to the referring clinician who will present the findings to the patient. Treatment options are often discussed as well depending on the outsourcing plan.
There are several methods that are used for the transfer of data from a sleep center to a sleep tech for sleep study scoring services. A common technique is File Transfer Protocol (FTP). This allow for encrypted data transfer of sleep studies from one computer to another.
