Brief summary
The purpose of this study is to describe biological stress (cortisolemia) and perceived stress in Emergency Call Center Operators and Doctors while processing a center 15 call.
Detailed description
Sample description : qualitative variables be expressed as percentages, numbers and 95% confidence intervals Quantitative variables will be expressed as means, standard deviations or medians, range, interquartile intervals Description of biological stress : it will be described by calculating the difference between the observed peek or peeks of cortisol ans the cortisol level measured at rest (means, standard deviations or medians, range, interquartile intervals) Description of perceived stress : the AVS will be described in terms of means and standard deviation Comparison of the peek-delta/base level of cortisol in the 3 different workstations of the call center operators according to the non parametrical Kruskall Wallis test. Same for the lengthof service of the call operator, the severity of the call and the status of the doctor The AVS score (perceived stress) will be compared to the peek-delta/base level of cortisol (biological stress) thanks to the Spearmann correlation coefficient.
Interventions
OTHERsalivary sampling by a biomnis swab
Each call operator will have a series of salivary sampling taken when assigned to call reception, to the unit deployment station and to the assessment station. Only one sampling will occur to doctors who are assigned to a single workstation. Sampling will be taken every 15 minutes during one hour and half and one last sample will be taken 2 hours after the call. To improve interpretation of the results, a series of control-samples will be taken among the call operators and doctors during a day off and not during a security break. There will be 4x8 samples taken for each call operator and 2x8 samples per doctor. They will also be frozen at a temperature of -4°C and sent to the laboratory of the CHR Metz Thionville.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| biological stress by salivary cortisol secretion | every 15 minutes after the emergency call and during 2 hours |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| perceived stress : VAS and SPPN questionnaire | VAS is assessed four times (once after each emergency call) during the first salivary sampling. SPPN once, on day 1, remote the emergency call (within the hourspreceding or following the emergency call) | SPPN : Negative and Positive Professional Stress, before the first salivary sampling. VAS : Visual Analogic Scale, |
