简要总结
The purpose of the current proposal will be to examine the clinical performance of both physicians in training as well as experienced faculty in pre and post call situations. Groups will be matched for gender, age, experience and employment duration during regular hours versus immediate post call hour.
详细描述
This is a prospective study evaluating the reaction time among attending anesthesiologists, and anesthesiology residents who take night shift call and are suffering from sleep deprivation. Investigators plan to examine clinical performance by measuring reaction times using a 10 minute psychomotor vigilance test device on physicians in training as well as experienced physicians in pre and post call situations.
All subjects will be informed of the scope and purpose of the study.
- Attending Anesthesiologists: Gender, age, years of experience, years of employment at the institution, hours of sleep and circadian rhythm will be taken into effect.
- Residents/Fellows: Gender, age, years of experience, years of employment at the institution and circadian rhythm will be taken into effect.
All study subjects will be asked to fill a questionnaire regarding demographic data, coping strategy Index.
- Baseline instruments; including demographics, and coping strategy indicator (CSI), will be administrated.
- Reaction time, mood and simple cognitive test will be measured at approximately 7 am of a regular day, (when the subject is not on call).
- Reaction time, mood and simple cognitive test will be measured at approximately 7 am of after a call night.

结局指标
主要结局
Profile of mood states
时间窗: Regular Day and Post-call shifts - Through study completion, an average of one year.
Subjective evaluations of mood will be made with the Profile of Mood States (POMS). The POMS is a 65-Item questionnaire which, when scored according to the specific templates, measures affect or mood on scales: 1) Tension-Anxiety, 2) Depression-dejection, 3) anger-hostility, 4) vigor-activity, 5) fatigue-inertia, and 6) confusion-bewilderment. Factor scores on each scale will be analyzed.
Reaction time
时间窗: Regular Day and Post-call shifts - Through study completion, an average of one year.
We plan to measure reaction times via a 10-minute psychomotor vigilance test (PVT, Ambulatory Monitoring Inc., NY) device. The PVT-192 Psychomotor Vigilance Task Monitor is a hand-held, self-contained system used for repetitive reaction time measurements.
Visual Analog Scale
时间窗: Regular Day and Post-call shifts - Through study completion, an average of one year.
Subjective sleepiness and alertness (and other parameters) will be measured via the Visual Analog Scale (VAS). This Questionnaire consists of several 100 millimeter lines, each of which is labeled at one end with the words "not at all" and the other end with the word "extremely". Centered under each line are the test adjectives which are as follows: "alert, able to concentrate, " anxious", "energetic", "feel confident", "irritable", "Jittery/nervous", "sleepy", and "talkative". The participants indicate the point on the line, which corresponded to the way they feel along the continuum at the time the test is taken. The score for each item consists of a number of millimeters from the left side of the line to the location at which the participants placed their mark.
