Page 4 Objectives 1. Recognize universal need for adequate sleep 2. Review risks of sleep deprivation 3. Consider methods to promote alertness when sleep-deprived 4. Consider methods to reduce risk of fatigue- related errors 5. Identify methods to recover from sleep deprivation 6. Review preventive measures

© American Academy of Sleep Medicine American Academy of Sleep Medicine Sleep Needed vs Sleep Obtained Myth: “ I’m one of those people who only need 5 hours of sleep, so none of this applies to me.” Fact: Individuals may vary somewhat in their tolerance to the effects of sleep loss, but are not able to accurately judge this themselves. Fact: Human beings need 8 hours of sleep to perform at an optimal level. Fact: Getting less than 8 hours of sleep starts to create a “sleep debt” which must be paid off.

© American Academy of Sleep Medicine American Academy of Sleep Medicine Drive Smart; Drive Safe AVOID driving if drowsy. If you are really sleepy, get a ride home, take a taxi, or use public transportation. Take a 20 minute nap and/or drink a cup of coffee before going home post-call. Stop driving if you notice the warning signs of sleepiness. Pull off the road at a safe place, take a short nap.

Page 16 “Alertness management” strategies Caffeine Exercise Light Napping Medication

Page 17 Caffeine Time use judiciously e.g. before circadian low point Onset: min Effects last 3-4 hours But, sleep-disruptive: if possible, d/c 3-4 hours before planned sleep

Page 18 Exercise Stretch, run in place, or do jumping jacks Walk briskly from house to car, car to hospital

Page 19 Light Best: full- spectrum light (e.g. sunlight) Any bright light helps

Page 20 Napping minutes Up to 2:00 (allows REM + restorative sleep) BUT longer naps > risk of sleep inertia

Page 21 Medication Modafinil ONLY IF PRESCRIBED by your personal physician

Page 22 And watch out for these Microsleeps Sleep inertia Circadian lows Isolation Self-deception High risk jobs

Page 23 Microsleeps “Faceplants”,or “nodding off” Sleeper often unaware Alert your colleagues! Response: thank colleague; exercise; talk

Page 24 Sleep Inertia: min of grogginess, cognitive slowing, decreased vigilance after awakening. Worsened by sleep deprivation

Page 25 Circadian lows 12-4 a.m p.m.

Page 26 Isolation: sleepiness predicts underestimates of level of sleepiness and overestimates of alertness; residents in 1 study did not perceive themselves to be asleep almost half of the time they had actually fallen asleep (Howard et al, 2002)

Page 27 Self-deception “If I can just get through the night (on call), I’m fine in the morning.” “I’m better off ‘toughing it out’, napping just makes me feel worse.” “I get used to night shifts right away; no problem.”

Page 28 High-risk jobs low stimulation + high need for vigilance

© American Academy of Sleep Medicine American Academy of Sleep Medicine Adapting To Night Shifts Myth: “I get used to night shifts right away; no problem.” Fact: It takes at least a week for circadian rhythms and sleep patterns to adjust. Fact: Adjustment often includes physical and mental symptoms (think jet lag). Fact: Direction of shift rotation affects adaptation (forward/clockwise easier to adapt).

© American Academy of Sleep Medicine American Academy of Sleep Medicine How To Survive Night Float Protect your sleep. Nap before work. Consider “splitting” sleep into two 4 hour periods. Have as much exposure to bright light as possible when you need to be alert. Avoid light exposure in the morning after night shift (be cool and wear dark glasses driving home from work).

Page 31 Recovering from sleep deprivation On average, two nights’ recovery sleep (approx 9 h) needed

Page 32 Preventive measures Sleep ahead: Optimize your sleep environment –Cool, dark, quiet Practice good sleep hygiene –Presleep relaxation, reduce alerting stimuli, make bed a cue for sleep

Page 33 © American Academy of Sleep Medicine American Academy of Sleep Medicine In Summary… Sleepiness and fatigue can’ t be eliminated in residency, but can be managed. Recognizing sleepiness and fatigue in yourself and your colleagues is the 1st step Practice alertness management strategies regularly Don’t overlook recovery periods If self-management isn’t working, talk to your seniors and/or program director
