Trial Outcomes & Findings for Lavender vs Zolpidem Sleep Quality During Diagnostic PSG (NCT NCT04102345)

NCT ID: NCT04102345

Last Updated: 2021-03-17

Results Overview

Percentage of total time in bed actually spent in sleep. It is calculated as sum of Stage N1, Stage N2, Stage N3, and REM sleep, divided by the total time in bed and multiplied by 100. A higher percentage is indicative of more efficient sleep.

Measure
Lavender
1-2 drops of Lavender (essential oil) in approximately 120 ml of distilled water is added to a diffuser 10 minutes before light out. The diffuser runs for approximately 2 hours before automatically being shut off. A low mist option is used on the diffuser. Lavender Aromatherapy: Commercially available lavender essential oil and diffuser.
Zolpidem
Pre-prescribed, physician directed use of zolpidem. There is no dose exclusionary criteria for the zolpidem. This study does not have any dose specifications, anyone on zolpidem may be eligible. Zolpidem: Physician directed, pre-prescribed. Study team does not prescribe zolpidem.

Percentage of total time in bed actually spent in sleep. It is calculated as sum of Stage N1, Stage N2, Stage N3, and REM sleep, divided by the total time in bed and multiplied by 100. A higher percentage is indicative of more efficient sleep.

SECONDARY outcome

Timeframe: 1 day

A binary outcome (yes/no) based on chart review. The outcome will be inferred from documentation in the chart either in notes or PSG report showing a successful split night or if a diagnosis is made or if a repeat PSG is ordered. Yes is a successful PSG.

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 day

Total amount of sleep time scored during the total recording time; includes time from sleep onset to sleep offset and is distributed throughout the sleep time as minutes of Stage N1 sleep, Stage N2 sleep, Stage N3, and rapid eye movement (REM) sleep. A longer total sleep time would be a higher number of minutes.

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 day

Time in minutes from 'lights off' that marks the starting of total recording time to the first epoch scored as sleep. This is how long one takes to fall asleep. A higher number of minutes is indicative of a higher sleep onset latency.

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 day

Rapid eye movement latency is the time in minutes from the sleep onset to the first epoch of REM sleep. This is the time one takes to transition from non-REM to REM sleep. A high number of minutes indicates a longer sleep latency.
