Step 1: | Patient maintains a daily sleep diary for 1 to 2 weeks. Average total sleep time and sleep efficiency are computed from the information on the sleep diary*. |
Step 2: | If sleep efficiency is below 85%, the time in bed window (ie, elapsed time from bedtime to rise time) is set to equal the number of hours of sleep based on the sleep diary with a consistent bedtime and rise time each day. The patient is instructed not to nap during the day. The patient continues to keep a sleep diary until the next visit. |
Step 3: | Average total sleep time and sleep efficiency are computed from the information on the sleep diary, and one of the following steps is taken:
|
Step 4: | Step 3 is repeated until sleep quality is satisfactory (refer to step 3A above) and the patient feels sufficiently rested during the day. |
