CRANIAL COMPLICATIONS
c(““,”“)
ICP - INTRACRANIAL HYPERTENSION
Definition
Intracranial pressure that is equal to or greater than 20 millimeters of mercury
Form
[X] Form 1
[ ] Form 2
Source
Abstraction (acute record)
Details
Patient must have an ICP monitor in order to code this variable other than ‘88. Not Monitored’ or ‘99. Unknown.’
If intracranial pressure is measured in cmH2O, use the following conversion formula: 1 mmHg = 13.6 cmH2O
ICP monitors are sometimes referred to by brand name in medical records. Examples of different brands of ICP monitors include Ventric, and Codman.
A single spike of 20mm/Hg or greater during a surgical procedure should not be counted as a ‘Yes’ for this variable.
Values labeled CPP (cerebral perfusion pressure) are sometimes listed under ICP monitoring and should NOT be used. CPP monitoring is also measured in mmHg, and should not be confused with the recorded ICP values.

History
Date | Description |
---|---|
1994-02-01 | Changed CODE : code 2 means less than or equal to 24 hours duration. |
1999-07-01 | Changed CODE : to clarify coding of fluctuating ICP. |
1999-07-01 | Added NOTE : regarding conversion from cmH2O to mmHg. |
2010-07-01 | Added NOTE : regarding brands of ICP monitors that may be referred to in medical records. |
2014-10-01 | Added NOTE : A single spike of 20mm/Hg or greater during a surgical procedure should not be counted as a 'Yes' for this variable. |
2016-04-01 | Changed CODE : revised Codes 2,3 and 4 to better clarify when fluctuations occur and when peaks happen |
2017-10-17 | Added NOTE : values labeled CPP (cerebral perfusion pressure) are sometimes listed under ICP monitoring and should NOT be used. CPP monitoring is also measured in mmHg, and should not be confused with the recorded ICP values. |

SEIZURES POST INJURY
Definition
Seizures present post-injury, and if so, when they occurred. May include seizures at more than one time point.
Form
[X] Form 1
[ ] Form 2
Source
Abstraction (acute and rehabilitation record)
Details
To be collected from the acute and rehabilitation record.
Data sources include EMS, ED, Progress, DC notes, and EEG reports.
If seizure occurs exactly 24 hours post injury, code “Seizures between 24 hours and 7 days after injury” as “Yes”.
If individual had premorbid seizures and drug treatment but no seizures during this hospitalization, code as “absent”.
Seizure can be witnessed by anyone, but must be suspected as a seizure by medical staff notation in the medical chart as seizure, likely/probable seizure, seizure like activity or EEG report.
