short_title

HEMORR₂HAGES Score

med_description

Quantifies risk of hemorrhage in elderly patients with AFib.

description

The HEMORR2HAGES Score quantifies the bleeding risk for elderly patients with atrial fibrillation who are anticoagulated with coumadin/warfarin.

evidence

One meta analysis (see references, below) specifically recommends using the HAS-BLED Score over the HEMORR₂HAGES Score because of the former's greater sensitivity (the latter, however, did have better specificity).

pearls

The HEMORR₂HAGES score was developed to quantify the risk of hemorrhage in patients with atrial fibrillation on anticoagulation and to aid in the management of antithrombotic therapy.

  • Combined hemorrhage risk factors from three previously existing clinical prediction rules to form the HEMORR₂HAGES mnemonic.
  • Validated the score by retrospectively applying it to a cohort of patients from the National Registry of Atrial Fibrillation database.
  • Scoring system consists of eleven criteria, one of which (history of prior bleeding) is worth 2 points, while the other ten are worth 1 point each.
  • For the basis of comparison to other bleeding risk schemes, patients with a score of 0 or 1 were classified as low-risk, 2 or 3 intermediate-risk, ≥4 high-risk.
  • Study found that the number of bleeds per 100 patient-years of warfarin increased as their HEMORR₂HAGES score increased.
  • For patients on warfarin, study found that HEMORR₂HAGES was more discriminatory compared to the other schemes.

Points to keep in mind:

  • Degree of hemorrhage was not examined in the study; all study patients with ICD-9 codes for active hemorrhage in any location were included.
  • The genetic risk factor was included in their score, but not actually tested in their cohort of patients.
  • There were variable definitions of hepatic or renal disease, thrombocytopenia depending on the state in which the patient lived.
  • All data was obtained retrospectively, via chart review and ICD-9 codes. Events occurring outside of the hospital or coded incorrectly were not included.
  • Anemia, malignancy and uncontrolled hypertension were included in a patient’s score if they were entered in as ICD-9 diagnoses, regardless if they were clinically important or not (e.g. distant history of cancer which has been in complete remission would still count as malignancy by ICD-9).
  • Excessive fall risk was determine by chart review for “high risk of falling, dementia, Parkinson's disease, or psychiatric disease.”
  • Study also examined ASA usage, but does not present specific data on the risk of hemorrhage on ASA with different HEMORR₂HAGES scores.
  • There was no comparison to more recently derived bleeding risk scores such as ATRIA or HAS-BLED.

A subsequent systemic review and meta-analysis comparing the performance of HAS-BLED, ATRIA and HEMORR₂HAGES recommended HAS-BLED for the assessment of atrial fibrillation patients’ major bleeding risk. The analysis found that HEMORR₂HAGES had a higher diagnostic accuracy, but considered it difficult to use due to its complexity.

usecase

Consider using the HEMORR₂HAGES score to stratify patients’ risk for bleeding after anticoagulation for atrial fibrillation in conjunction with situation specific risks/benefits.

reasons

Combines components from several other previously validated bleeding risk scores into one.

next_advice

next_actions

  • Risks and benefits of anticoagulation should be carefully considered in ALL patients prior to initiating therapy.
  • Other risk stratification scores such as HAS-BLED or ATRIA should also be taken into consideration prior to starting anticoagulation.
  • Alternative options should often be considered in patients with high-risk of major bleeding events in need of anticoagulation.
