You can see for yourself that the
telephone interview for cognitive status questions really have little objective correlation with where the damage is located.
The
Rankin scale has no useful discrimination at all except for no. 6 - dead.
See page 3 and 4 here for
Sickness Impact Profile questionnaire. Nothing objective about that since the patient is answering the questions.
At least the
apache ii acute physiology score seems to contain objective measurements.
No looking at all at 3d representations of the dead and damaged areas. Does anyone have two neurons to rub together in stroke?
Do you really trust prediction scores based on this for your loved one?

Abstract
OBJECTIVE:
To
create a multi-dimensional tool to prognosticate long-term functional,
cognitive, and quality-of-life outcomes after spontaneous subarachnoid
hemorrhage (SAH) using data up to 48 hours after admission.
METHODS:
Data
were prospectively collected for 1619 consecutive patients enrolled in
the SAH-outcome-project 07/1996-03/2014. Linear models (LM) were applied
to identify factors associated with outcome in 1526 patients with
complete data. 12-months functional, cognitive, and quality-of-life
outcomes were measured using the Modified-Rankin-scale (mRS),
Telephone-Interview-for-Cognitive-Status and the
Sickness-Impact-Profile. Based on the LM-residuals, we constructed the
FRESH-score (Functional Recovery Expected after Subarachnoid
Hemorrhage). Score performance, discrimination and internal validity
were tested using the area under the
receiver-operating-characteristic-curve (AUC), Nagelkerke's and
Cox/Snell's R-Squares, and bootstrapping. For external validation we
used a control population of SAH-patients from the CONSCIOUS-1-study
(n=413).
RESULTS:
The
FRESH-score was composed of: Hunt&Hess and APACHE-II-physiologic
scores on admission, age, and aneurysmal rebleed within 48 hours.
Separate scores to prognosticate 1-year cognition (FRESH-cog) and
quality-of-life (FRESH-quol) were developed controlling for education
and premorbid disability. Poor functional outcome (mRS4-6) for
score-levels 1 through 9 respectively was present in 3, 6, 12, 38, 61,
83, 92, 98 and 100% at 1-year-follow-up. Performance of FRESH (AUC
0.90), FRESH-cog (AUC 0.80) and FRESH-quol (AUC 0.78) was high. External
validation of our cohort using mRS as endpoint showed satisfactory
results (AUC 0.77). To allow for convenient score calculation we built a
smartphone-app available for free download.
INTERPRETATION:
FRESH
is the first clinical tool to prognosticate long-term outcome after
spontaneous SAH in a multidimensional manner. This article is protected
