Summary
Implementing prescriber guidelines significantly improved anticoagulation initiation for thrombotic disorders. This led to reduced heparin duration and faster warfarin start times, enhancing patient care.
Area of Science:
- Clinical Medicine
- Pharmacology
- Health Services Research
Background:
- Anticoagulation therapy is crucial for managing thrombotic disorders.
- Inefficient initiation of anticoagulation can lead to suboptimal patient outcomes.
- Previous audits identified delays and inefficiencies in anticoagulation protocols.
Purpose of the Study:
- To enhance the process of initiating anticoagulation in patients with thrombotic conditions.
- To evaluate the impact of implementing standardized prescriber guidelines on anticoagulation initiation.
Main Methods:
- A pre- and post-intervention audit design was employed.
- Intervention involved disseminating pocket-sized prescriber guidelines and posters.
- Medical records of inpatients receiving intravenous heparin followed by warfarin were prospectively assessed.
Main Results:
- Mean intravenous heparin duration decreased from 150 to 97 hours (P < 0.002).
- Mean delay in initiating warfarin decreased from 69 to 21 hours (P < 0.002).
- Therapeutic range for activated partial thromboplastin time (aPTT) increased from 30% to 44% (P < 0.05).
Conclusions:
- Implementation of guidelines led to significant improvements in anticoagulation initiation.
- Guidelines were broadly accepted into clinical practice, driving positive changes.
- No increase in adverse hemorrhagic events was observed.
