Notes:
To standardize data collection and processing procedures, three Veterans Administration sleep laboratories established standard procedures “on paper,” implemented them in a study, and assessed scoring agreement for sleep EEG-EOG recordings. The first phase of the study resulted in a detailed written description of all basic procedures. For the second, each laboratory evaluated 6 mentally and physically healthy males on three consecutive nights. Overall scoring agreement was about 90%. It was at least 89% between pairs of laboratories for stage 0, 59% for stage 1, 95% for stage 1 REM, 92% for stage 2, and 80% for stages 3+4. Values for standard sleep EEG-EOG parameters were generally similar among scoring laboratories, and interlaboratory scoring agreement compared favorably with one measure of intralaboratory agreement. The low agreement for stage 1 is attributable to the infrequent and sporadic occurrence of stage 1 and is considered to be trivial. That for stages 3+4 is more critical and is probably related to the subjective process involved in scoring these stages. These data indicated that these techniques produced a high degree of interlaboratory standardization, and consequently, concurrence in sleep stage scoring.
