Summary
Oculoplastic surgeons vary in managing aspirin and warfarin before surgery. Over half report complications from altering anticoagulation, highlighting a need for standardized preoperative guidelines to minimize patient risk.
Area of Science:
- Ophthalmology
- Cardiology
- Surgery
Background:
- No national guidelines exist for preoperative management of patients on aspirin or warfarin.
- Evidence suggests low complication rates in anticoagulated patients versus higher thromboembolic risks with therapy manipulation.
Purpose of the Study:
- To survey oculoplastic and ophthalmic surgeons' practices regarding aspirin/warfarin in patients undergoing oculoplastic surgery.
- To assess complication rates associated with current management strategies.
Main Methods:
- Anonymous postal questionnaire survey distributed to ophthalmic consultants, specialist registrars, and oculoplastic specialists.
- Targeted surgeons in the Wessex and Southern regions.
Main Results:
- High response rate (92%).
- Surgeons were more likely to alter warfarin than aspirin therapy.
- 18% allowed insufficient time for coagulation changes; 54% reported complications from anticoagulation management.
Conclusions:
- At least half of surveyed surgeons consider stopping warfarin before oculoplastic procedures.
- Over half of surgeons have encountered complications, some serious, related to aspirin or warfarin management.
- A need for a standardized approach to minimize patient risk is indicated.
