Complete a HAS-BLED Score Assessment and Log it to an EMR Automatically
Dot phrase template for assessing bleeding risk in Atrial Fibrillation patients using the HAS-BLED score.
Copy templates to use them anywhere:
The American College of Cardiology cites the HAS-BLED score as an effective means of assessing stroke risk.
This snippet runs through each question in the HAS-BLED assessment, outputting a score and risk. Easily add the assessment and results to a patient's chart in your EMR.
The HAS-BLED assessment may be used in conjunction with the CHA2DS2-VASc Score
HAS-BLED score
Hypertension: {formmenu: default=; yes; no; name=hypertension}
Uncontrolled, >160 mmHg systolic
Renal Disease: {formmenu: default=; yes; no; name=renal} Dialysis, transplant, Cr >2.26 mg/dL or >200 µmol/L
Liver Disease: {formmenu: default=; yes; no; name=liver} Cirrhosis or bilirubin >2x normal with AST/ALT/AP >3x normal
Stroke History: {formmenu: default=; yes; no; name=stroke}
Prior major bleeding or predisposition to bleeding: {formmenu: default=; yes; no; name=prior}
Labile INR: {formmenu: default=; yes; no; name=labile} Unstable/high INRs, time in therapeutic range <60%
Age >65 {formmenu: default=; yes; no; name=age}
Medication usage predisposing to bleeding: {formmenu: default=; yes; no; name=medication} Aspirin, clopidogrel, NSAIDs
Alcohol use: {formmenu: default=; yes; no; name=alcohol} ≥8 drinks/week
{=score} points {if: score=0}Risk was 0.9% in one validation study (Lip 2011) and 1.13 bleeds per 100 patient-years in another validation study (Pisters 2010).
Anticoagulation should be considered: Patient has a relatively low risk for major bleeding (~1/100 patient-years).{elseif: score=1}Risk was 3.4% in one validation study (Lip 2011) and 1.02 bleeds per 100 patient-years in another validation study (Pisters 2010).

Anticoagulation can be considered, however patient does have moderate risk for major bleeding (~2/100 patient-years).{elseif: score=3}Risk was 5.8% in one validation study (Lip 2011) and 3.72 bleeds per 100 patient-years in another validation study (Pisters 2010).
Alternatives to anticoagulation should be considered: Patient is at high risk for major bleeding.{elseif: score=4}Risk was 8.9% in one validation study (Lip 2011) and 8.70 bleeds per 100 patient-years in another validation study (Pisters 2010).
Alternatives to anticoagulation should be considered: Patient is at high risk for major bleeding.{elseif: score=5}Risk was 9.1% in one validation study (Lip 2011) and 12.50 bleeds per 100 patient-years in another validation study (Pisters 2010).
Alternatives to anticoagulation should be considered: Patient is at high risk for major bleeding.{elseif: score>5}Scores greater than 5 were too rare to determine risk, but are likely over 10%.
