17
Q

What must be evaluated with regards to potential cause for mental status changes?

A

Underlying causes like medication history, vital signs, ect.

18
Q

Can lab testing, imaging, and EEGs substitute for H&P in the diagnosis of delirium?

A

NO

19
Q

What might lab testing, imaging, and EEGs be useful for in the diagnosis of delirium?

A

To identify possible causes of delirium and contributing factors

20

Q

What is considered the treatment of choice?

A

High potency antipsychotics

23
Q

Why are high-potency anti psychotics considered the treatment of choice?

Because they have low anticholingergic potency and minimal risks for hypotension or respiratory depression

24

A
  • Haloperidol
  • Olnzapine
  • Quetiapine
  • Risperidone
  • Lorazepam

A

15-25%

26
Q

What is the % range of post-op delirium rates among seniors after a high-risk procedure like a hip fracture or cardiac surgery?

A

Over 50%

27
Q

What % of delirium cases go unrecognized and undocumented by the treating clinical team?

A

50-80%

28
Q

What is the timeline for patient with delirium who will probably fully recover?

A

Delirium that persists for less than 2 weeks

29
Q
