=== Sedated or Paralyzed Patients ===
*FOR non-neuro or post op patients:  Being sedated or paralyzed may not allow us to accurately assess neurological status. For '''sedated''' or '''paralyzed''' patients consider their likely neurological status prior to sedation or paralysis or status when sedation wears off.
* when using information that was '''documented prior to sedation/paralysis''' or POST OP use "best guess" based on chart notes.
*trauma or neuro patient: (when sedated) use "Best score" in first 24 hours of admission to ICU.
 
====Discussion====
 
* The important thing to keep in mind when doing apache GCS is that it focuses on the first 24 hours.  If a patient comes in sedated,and remains sedated for the first 24 hours and there is clear documentation about GCS just prior to sedation (for example in ER), then you can use this information.  If the patient is sedated and there is no documented GCS prior to sedation, you can use once the sedation is reduced '''if''' it is close to the 24 hour mark.  Otherwise, if it is days later, there is no guarantee that this was correct during the first 24 hours.  The guidelines say to put the value as normal if unable to obtain this information close to the 24 hour timeframe.--[[User:LKolesar|LKolesar]] 12:09, 17 October 2008 (CDT)
 
* In terms of patients where brain injury is in question and the pt. remains sedated for several days, therefore making an accurate determination of GCS impossible, we are still debating as to whether a normal GCS should be used.  This is being worked on by the Task Group.  Right now, according to Trish, until we have a decision to change the guideline, we should be using our own judgement as far as assessment once the sedation is worn off. --[[User:LKolesar|LKolesar]] 13:02, 17 October 2008 (CDT)
** For purposes of calculating scores off the GCS, would leaving it blank result in a score as if coded as "normal"?[[User:Ttenbergen|Ttenbergen]] 13:28, 17 October 2008 (CDT)
** We're not sure if we will leave it blank but this would not result in a normal score, it would just mean there was insufficient data to have an accurate GCS.  This is still under review and data collectors should still use the guideline of using our own judgement to score the patient in the case of lack of information.  --[[User:LKolesar|LKolesar]] 11:47, 21 October 2008 (CDT)
 
=== Patients following drug overdose where outcome uncertain ===

What should be coded for patients who had a drug overdose where the outcome is not clear during the GCS time frame? [[User:Ttenbergen|Ttenbergen]] 14:10, 16 October 2008 (CDT)
 
==From general guide needs reviewing==
For Head traumas select the '''worst''' score in the first 24 hours in ICU. If sedated or paralyzed select the '''best''' score in the first 24 hours in ICU prior to sedation.
For non neuro & post operative patients who are sedated or paralyzed, please record a '''normal''' neuro score, unless there is a neurological problem.  If this is the case, you must select the select the '''worst''' values prior to sedation or “best guess” based on history prior to sedation. 
Sedation does not allow us to accurately assess Neuro status, therefore we use alternative information that was documented prior to OR or sedation or we use our “best guess” base on chart notes.
==== to do before de-stubbing ====
* what does "best score" mean in this context? Best to make the patient score a high APACHE, or best to let him live?
* in case of sedation or OR, what is the precedence of "alternative" information vs. chart? Are the two not the same?

*You refer to brain injury, trauma and neuro patient in different statements.  Could you be more clear and explain why you treat trauma differently than just 'neuro'.  --[[User:Jpeterson|Jpeterson]] 10:13, 2012 December 4 (EST)

=== Medicated Patients ===
If a patient is unable to respond to GSC questions because they are medicated (e.g. sedated or paralyzed), and there is no reason to expect that their response would be impaired if they were not medicated, they can be scored to a GCS assessment immediately prior to medication if available, e.g. from the ER. If the patient is sedated and there is no documented GCS prior to sedation, you can use a GCS assessment once the sedation is reduced '''if''' it is close to the 24 hour mark.

The Glasgow Coma Scale (GCS) is a neurological assessment scale which aims to give a reliable, objective way of quantifying level of consciousness. [1] The Glasgow Coma Score is also used as part of the APACHE II assessment score for Critical Care Program and the MOST assessment score for Medicine Program. Due to this use as part of APACHE we need the worst GCS in the first 24hrs (like all other APACHE elements).

Instructions

Select the worst Eye, Motor or Verbal response in the first 24 hours after admission to ICU from the dropdown lists in CCMDB.mdb.

Special Cases

The below are only meant to help you use your judgement keeping in mind that our purpose for the GCS is to understand what the state of consciousness was, and how it should impact, the APACHE score, i.e. the status of the patient within the first 24hrs.

Patients with normally limited communication ability

For patients whose ability to communicate are reduced due to pre-existing conditions, score as fully functioning if they are able to function at the level that is normal for this patient. (e.g. Down's syndrome)

Patients who fail assessments for reasons other than consciousness

Patients who are aphasic or intubated but clearly can communicate in writing should be coded as functioning normally. Same is true for patients whose eyes are swollen shut etc. [2]

Medicated Patients

If a patient is unable to respond to GSC questions because they are medicated (e.g. sedated or paralyzed), and there is no reason to expect that their response would be impaired if they were not medicated, they can be scored to a GCS assessment immediately prior to medication if available, e.g. from the ER. If the patient is sedated and there is no documented GCS prior to sedation, you can use a GCS assessment once the sedation is reduced if it is close to the 24 hour mark.
