Study Details

Study Description

Brief Summary

If operating on the anticoagulated patient has been safe for one of the investigators' surgeons for the past 10 years then providing prospective data that substantiates this could prevent complications related to the discontinuation of anticoagulation for hand surgery patients in the future.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    All eligible patients will be offered study enrollment pre-operatively. Demographic data collected during clinical interaction that will be gathered for research purposes and will included patient height, weight, age, anticoagulant medication(s) used with dosage/duration of use, indication for anticoagulant medication, and current INR if on warfarin. Preoperative examination will include measures of 2 point discrimination in the digits, distance of the fingertips from the distal palmar crease upon flexion, and the patient-based outcome surveys that are to be collected after surgery (Quick DASH, SF-12, Visual Analog Scales pain/swelling). These patients will then undergo the appropriate surgical procedure without discontinuing their anticoagulant medication.

    To ensure that patients are not being placed at increased risk, this study's protocol will not alter the surgical practices of the attending surgeons involved. Specifically, all surgeons perform their hand and wrist surgery under tourniquet control but differ in whether the tourniquet is deflated prior to wound closure. Each surgeon will be free to manage the tourniquet as they feel appropriate. The placement of would drains will remain at the discretion of the attending surgeon on a case-by-case basis.

    Local anesthetics may be injected but none will be mixed with epinephrine.

    Procedures: (if applicable) Obtaining pre-operative INR values when appropriate, and performing surgery while continuing anticoagulants is already standard care for one faculty member. All post-operative care except the completion of the Quick DASH and Short Form 12, and visual analog ratings is part of standard clinical care. Research questionnaires should take no more than 20 minutes to complete per visit.
