Prescribing Safety Assessment (PSA) Practice Exam

Which of the following is a factor considered in the HAS-BLED scoring system?

1. Age - over 60

2. Heart failure class

3. Creatinine level

4. Use of beta blockers

The correct answer is: Creatinine level

In the HAS-BLED scoring system, which is used to assess the risk of bleeding in patients undergoing anticoagulation therapy, creatinine level is indeed a critical factor. Specifically, the scoring system incorporates renal function, which is evaluated through serum creatinine levels. Increased creatinine levels indicate renal impairment, which is a significant risk factor for bleeding complications in patients taking anticoagulants, as diminished kidney function can lead to the accumulation of these drugs. Each factor in the HAS-BLED score serves to identify patients who may benefit from careful monitoring or alternative treatment strategies. While age over 65, heart failure, and the use of certain medications do play roles in assessing overall bleed risk, the inclusion of creatinine level focuses specifically on renal status, underlining the importance of kidney function in managing bleeding risk.
