Paroxysmal Sympathetic Hyperactivity Assessment Measure

• 

• 

Use CFS + DLT for diagnosis:

• <8 = PSH unlikely
• 8 to 16 = PSH possible
• ≥17 = PSH probable

If total score 8 or greater, then use the CFS scale for monitoring of evolution (document daily maximal score).

Unruptured Intracranial Aneurysm Treatment Score

UIATS = Unruptured Intracranial Aneurysm Treatment Score

• quantifies 29 key factors related to patient, aneurysm and treatment characteristics involved in clinical decision-making in management of unruptured aneurysm
• 2 scores generated – 1 favoring repair and the other favoring conservative management.
• For a score difference with >3 points, higher score suggests the type of treatment
• For a score difference with <=2 points, no definitive recommendations can be made

Risk Score to Predict QTc Prolongation in Hospitalized Patients

For patients with COVID-19, we are using drugs that prolong QT-interval.  The risk of life-threatening arrhythmias from QT prolongation may be higher.  This article reports a scoring system to identify patients that are at risk for QT prolongation.

The study found that the following factors predicted QTc prolongation:  female, sepsi, LV dysfunction, administration of QT-prolong drug, >= 2 QT prolonging drugs, loop-diuretic, age >68, serum K <3.5, admitting ATc >450ms.

A risk score was developed.  Risk was classified as low (score of 0-6), moderate (7-10) and high (11-21).

 

A high risk score >11 was associated with 74% Sn and 77% Sp (PPV 79% NPV 76) for predicting QTc prolongation.  Incidence of QTc prolongation 15% in low risk, 37% in moderate risk and 73% in high risk.

IVH Score

This score is used for patients with intracerebral hemorrhages with intraventricular extension, and is not appropriate for pure intraventricular hemorrhages.

In this score, each lateral ventricle is graded as:

• 0 = no blood or small amount of layering
• 1 = up to 1/3 filled with blood
• 2 = 1/3 to 2/3 filled with blood
• 3 = mostly or completely filled with blood

3rd and 4th ventricles receive a score of:

• 0 = for no blood
• 1 = partially or completely filled with blood

Hydrocephalus was coded as

• 0 = absent
• 1 = present

 

The formula for calculating the IVH score is as follows:

Or simplified:  3(RV+LV) + III + IV + 3(H)

 

Once the IVH score has been computed, the IVH volume can be calculated using the following formula:

 

To make things simpler, here is a table showing the calculated IVH volume based on the IVH score.

 

Here are two examples of IVH scores calculated for you:

 

How to use the IVH Score?

With the IVH score, cutoff of 40 mL indicates poor outcome and 60 mL, mortality.

With the ICH score, cutoff is 25 mL and 30 mL respectively.

The total volume of hemorrhage can be calculated by adding the ICH volume (using the ABC/2 formula) and the IVH volume (using the ICH score).   Total volume predicts outcome better than ICH volume alone.

 

NOTE:  Be wary of using ICH score and IVH score to withdraw care.  Early limitation of care in ICH / IVH is a self-fulfilling prophecy which is, of course, associated with mortality.

• • outpatient work-up within 1-2 days (alternate option: admit for work-up)
• DIAGNOSTICS:
• • carotid imaging (US, CTA, MRA)
• • Consider TTE; if high suspicion for cardioembolic source / bilateral infarcts, obtain TEE
• • Consider 30-d ambulatory cardiac monitor to detect cryptogenic Afib

• • • Start antiplatelet therapy:
• • • • ASA 81mg/day or
• • • • Clopidogrel 75mg/day or
• • • • ASA 25mg/ER dipyridamole 200mg BID
