AASM Inter-scorer Reliability Assessment System Tour

AASM Inter-scorer Reliability is a web-based assessment system for sleep technologists and other sleep professionals who score sleep studies. Designed and operated by the American Academy of Sleep Medicine, the system is intended as a tool for sleep facility managers to educate their staff while fulfilling the AASM Standard for Inter-scorer Reliability.

New Exams Each Month

A new sleep study record exam will become available every month. Each record exam consists of 200 continuous epochs from a sleep study patient. Users will have three months to score stages, arousals, respiratory events and limb movements for all 200 epochs.

Full Screen Epochs, Streamlined Scoring

AASM Inter-scorer Reliability received a complete system overhaul in 2012 to more closely resemble professional scoring software used in sleep centers. The interface is designed to run full screen in an internet browser, so that the records fill the entire window. Users can examine epochs in a standard 30-second duration, or use the 120-second view to review each in the context of surrounding epochs. Mark each epoch using menu overlays or hotkeys that support both single-pass and multipass scoring approaches.

New for Fall 2012

In September 2012, the AASM released the latest version of the Inter-scorer Reliability Assessment System. Upgrades and new features include:

Enhanced Performance

Major changes to the system programming dramatically reduce loading times for scorers. Users with even the slowest of internet connections should be able to score with few delays.

Customized Montages and Channel Settings

Adjust and arrange the channels on your records to suit user scoring preferences. Users can save their setups for use in future record exams.

Time Measurement System for Added Precision

Eliminate guesswork by clicking and dragging over the record to measure the exact length of every potential event.

Enhanced Reporting System

A full suite of advanced reports gives an in-depth look at each scorer's decisions, and compares your facility's results to other sleep centers.

Instant Scoring Feedback

Once each exam is complete, all scoring decisions will be compared to an AASM Gold Standard Scorer. Scorers will be able to review their entire record, with the Gold Standard score also displayed. Users are then encouraged to take advantage of education opportunities offered on the AASM Inter-scorer Reliability Assessment System.
