|Study Design:||Time Perspective: Prospective|
|Official Title:||Laparoscopic Skills and Cognitive Function Are Not Affected by Night Shifts in Surgeons|
- laparoscopic simulation [ Time Frame: pre call and on call ] [ Designated as safety issue: No ]
- d2 test of attention, Karolinska Sleepiness scale, actigraphy, prescribing medication in the EPM system, HRV, urine melatonine, saliva cortisol [ Time Frame: pre call, on call, post call, the second post call day ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples Without DNA
|Study Start Date:||December 2011|
|Study Completion Date:||March 2012|
|Primary Completion Date:||March 2012 (Final data collection date for primary outcome measure)|
The surgeons wore an actigraph consecutively on all 4 days, and would fill out a sleep diary on all 4 days as well. The surgeons were heart monitored consecutively on day 1 and 2.
The surgeons were tested in a laparoscopic simulator at 8 a.m. day 1, 4 a.m. day 2, and again at 8 a.m. day 4. At the same given times they would perform the d2 test of attention and prescribe medicine in the Electronic Patient Medication system in accordance with a case they were given. Furthermore they delivered a salivary sample for the determination of salivary cortisol, at the given times.
They sampled urine from 9 pm - 9 am all 4 days, in order to measure the production of melatonin in urine.
The surgeons would fill out the Karolinska sleepiness scale, VAS (Visual Analog Scale) fatigue, VAS sleep quality and VAS general well being at 8 a.m. day 1, 4 a.m. day 2, and again at 8 a.m. day 4. The Karolinska Sleepiness scale was filled out every second hour on day 2 from 4pm - 8 am on day 3.
