Outpatient Management of Anticoagulation Therapy - Article

ABSTRACT: The Seventh American College of Chest Physicians (ACCP) Conference on Antithrombotic and Thrombolytic Therapy provides guidelines for outpatient management of anticoagulation therapy. The ACCP guidelines recommend short-term warfarin therapy, with the goal of maintaining an International Normalized Ratio (INR) of 2.5 +/- 0.5, after major orthopedic surgery. Therapy for venous thromboembolism includes an INR of 2.5 +/- 0.5, with the length of therapy determined by associated conditions. For patients with atrial fibrillation, the INR is maintained at 2.5 +/- 0.5 indefinitely; for most patients with mechanical valves, the recommended INR is 3.0 +/- 0.5 indefinitely. Use of outpatient low-molecular-weight heparin (LMWH) is as safe and effective as inpatient unfractionated heparin for treatment of venous thromboembolism. The ACCP recommends starting warfarin with unfractionated heparin or LMWH for at least five days and continuing until a therapeutic INR is achieved. Because patients with venous thromboembolism and cancer who have been treated with LMWH have a survival advantage that extends beyond their venous thromboembolism treatment, the ACCP recommends beginning their therapy with three to six months of LMWH. When invasive procedures require the interruption of oral anticoagulation therapy, recommendations for bridge therapy are determined by balancing the risk of bleeding against the risk of thromboembolism. Patients at higher risk of thromboembolization should stop warfarin therapy four to five days before surgery and start LMWH or unfractionated heparin two to three days before surgery.


Venous Thromboembolism During Pregnancy - Article

ABSTRACT: Venous thromboembolism is the leading cause of maternal death in the United States. Pregnancy is a risk factor for deep venous thrombosis, and risk is further increased with a personal or family history of thrombosis or thrombophilia. Screening for thrombophilia is not recommended for the general population; however, testing for inherited or acquired thrombophilic conditions is recommended when personal or family history suggests increased risk. Factor V Leiden and prothrombin G20210A mutation are the most common inherited thrombophilias, and antiphospholipid antibody syndrome is the most important acquired defect. Clinical symptoms of deep venous thrombosis may be subtle and difficult to distinguish from gestational edema. Venous compression (Doppler) ultrasonography is the diagnostic test of choice. Pulmonary embolism typically presents postpartum with dyspnea and tachypnea. Multidetector-row (spiral) computed tomography is the test of choice for pulmonary embolism. Warfarin is contraindicated during pregnancy, but is safe to use postpartum and is compatible with breastfeeding. Low-molecular-weight heparin has largely replaced unfractionated heparin for prophylaxis and treatment in pregnancy.


Management of Hip Fracture: The Family Physician's Role - Article

ABSTRACT: The incidence of hip fracture is expected to increase as the population ages. One in five persons dies in the first year after sustaining a hip fracture, and those who survive past one year may have significant functional limitation. Although surgery is the main treatment for hip fracture, family physicians play a key role as patients' medical consultants. Surgical repair is recommended for stable patients within 24 to 48 hours of hospitalization. Antibiotic prophylaxis is indicated to prevent infection after surgery. Thromboprophylaxis has become the standard of care for management of hip fracture. Effective agents include unfractionated heparin, low-molecular-weight heparin, fondaparinux, and warfarin. Optimal pain control, usually with narcotic analgesics, is essential to ensure patient comfort and to facilitate rehabilitation. Rehabilitation after hip fracture surgery ideally should start on the first postoperative day with progression to ambulation as tolerated. Indwelling urinary catheters should be removed within 24 hours of surgery. Prevention, early recognition, and treatment of contributing factors for delirium also are crucial. Interventions to help prevent future falls, exercise and balance training in ambulatory patients, and the treatment of osteoporosis are important strategies for the secondary prevention of hip fracture.
