Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators will quantify the changes in sleep pattern and activity during different call rotations. Self reported aspects of well being including fatigue, physical function, and positive affect will be assessed with NIH PROMIS surveys periodically during the study period. The investigators will use the Fitbit Alta HR data to quantify the change in total amount of sleep, sleep interruption and sleep phase and steps per day. Data will be analyzed only when it is coincident with heart rate data to correct for periods when the device is not used.
Activity will not alter from the participants normal except that they will wear the Fitbit and respond to the NIH PROMIS surveys over the study period.
Data from NIH PROMIS surveys, Fitbit and provided demographic information including age, sex and BMI, and number of previous night float periods previously completed. After association, data will be completely de-identified.
All data will be normalized to the participant's baseline value during the run-in week. The call week and post call week will be analyzed with a time series mixed effects model using R and/or NONMEM (a program for Nonlinear Mixed Effects Modeling). The effects of the above demographic variables will be assessed as potential covariates.
The investigators anticipate that this observational study will be the first of many studies looking at the effects of changing sleep patterns on activity and well-being

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
General Anesthesia Night Float
The residents will be followed over a three week period - one week prior to night float (baseline), the week of night float, and one week after night float (recovery). Participants will be asked to fill out PROMIS surveys weekly.
No interventions assigned to this group
Obstetric Anesthesia Rotation
The residents will be followed and asked to wear the fitbit over a four week period during their rotation. Participants will complete three PROMIS surveys over the four week rotation, and as well as a follow-up PROMIS survey one week after the study period has completed
No interventions assigned to this group
