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.
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.
All study subjects will be asked to fill a questionnaire regarding demographic data, coping strategy Index.
This proposal attempts to examine the impact of night shift on mood, cognitive and motor task performance in physicians as compared to regular hours.

| Measure | Description | Time Frame |
|---|---|---|
| Reaction time | 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. | Regular Day and Post-call shifts - Through study completion, an average of one year. |
| Visual Analog Scale | 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. | Regular Day and Post-call shifts - Through study completion, an average of one year. |
| Profile of mood states | 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. | Regular Day and Post-call shifts - Through study completion, an average of one year. |
| Measure | Description | Time Frame |

| Coping Strategy Indicator (CSI): | This is the self-report measure of three fundamental modes of coping that has demonstrated considerable psychometric strength. The CSI first instructs responders to select a recent stressful event from their lives and briefly describe it. Then, responders read a list of 33 specific coping behaviors, indicating the extent to which each was used to deal with the problem. Responders are summed to form three scales: problem solving, seeking social support and avoidance. |
