Deep Vein Thrombosis (DVT) Education for Nurses

Deep Vein Thrombosis (DVT) Education for Nurses

Objectives Identify risk factors for the development of Deep Vein Thrombosis (DVT) Describe Discuss the nurse’s role in DVT prevention the process for DVT prophylaxis at LVH

Did You Know? Up to 2 million people in the United States suffer from DVT every year. 1 Approximately 600,000 experience pulmonary embolism (PE). 1 1. Venous Thromboembolism (VTE) is the term commonly used to describe both DVT and PE. Hirsh, Hoak. Circulation. 1996;93:2212-2245.

Did You Know? For up to 200,000 of those with PE, the blood clot in the lung proves fatal – killing more people than AIDS and breast cancer combined. 200000 150000 100000 Annual Number of Deaths 50000 0 PE 2-6 2. 3. 4. 5. 6.

Oh, I just saw Mrs. Smith in the ER last week with the flu. I wonder why she was admitted with DVT!!

Risk Factors for DVT Medical conditions, such as: Coronary Artery Disease Heart Failure Exacerbation of COPD or other severe respiratory disease Acute MI Trauma/Burns Sepsis Inflammatory bowel disease Lupus Stroke

Risk Factors for DVT 7,8 7. 8. Illness or injury that causes prolonged immobility Age 40 Pregnancy, birth control pills and hormone replacement therapy Cancer and its treatment Major surgery (ex: abdomen, pelvis, hip facture, knee fracture, hip or knee replacement) Surgery time 30 minutes Obesity Indwelling vascular devices Previous DVT or PE Geerts et al. Chest. 2001;119(suppl):132S-175S. National Experts’ Consensus Panel for Clinical Excellence in Thrombosis Management. Available at: http://www.thrombosis-consult.com.

I wonder if Mrs. Smith was at risk for DVT?

Was Mrs. Smith at Risk for DVT? 47 years old She is recuperating from surgery (abdominal hysterectomy) one month ago. She was just in the emergency dept. with flu-like symptoms; has spent the last 3 days in bed. She has a history of Lupus. Yes! She certainly had several risk factors. The more risk factors a patient has, the greater the risk for DVT.

Could Mrs. Smith’s DVT have been prevented? Evidenced based CHEST Guidelines recommend: – Identifying hospitalized patients that are at high risk for developing DVT Implementing interventions to prevent DVT

Let’s review the important interventions for the prevention of DVT: Ambulation early and often (simplest and most cost effective means to reduce risk of DVT) Intermittent External Compression Devices: Also called sequential compression devices or SCDs They increase rate/velocity of venous blood and reduce pooling in the peripheral veins Compression should begin pre-operatively and be continued until the patient is fully ambulatory Anticoagulant Medication Therapy

Medication for DVT Prevention Chest Guidelines recommend Enoxaparin for the prevention of DVT.

Medication for DVT Prevention Enoxaparin: Also known by the trade name Lovenox Always administered subcutaneously Usual dose is 40mg per day for medically ill patients If Creatinine Clearance is 30ml/min, adjusted dose is 30mg per day –

What’s happening at Lehigh Valley Hospital? We are focusing on DVT prophylaxis for all in-patient admissions. The following screen will be attached to all admission order screens in Last Word. Requires the physician to place the order for the appropriate DVT prophylaxis

Physician Order

Physician Order (continued) If DVT prophylaxis is NOT indicated . the reason must be identified.

Physician Order (continued) Reasons why prophylaxis may not be indicated include: Patient is fully ambulatory and is expected to be hospitalized for less than 24 hours The patient declines DVT prophylaxis The patient is fully anticoagulated

Physician Order (continued) The following screens show: How the order will appear on the patient’s active order list The detail screen for the order

Diagnosing DVT Clinical diagnosis of DVT is unreliable because classic symptoms (pain, swelling, tenderness, and warmth) may not be present. Therefore it is important for ALL healthcare professionals to collaborate in the identification of high risk patients and implement prophylaxis.

Patient Education It is important that our patients are included in the plan for prevention of DVT.

Patient Education Education material available to our patients includes: Patient education video “DVT Prevention” available on CCTV Written material: Learn More About Deep Vein Thrombosis Learn More About Pulmonary Emboli

Remember Major risk factors for DVT include: heart failure, severe respiratory disease and sepsis. All patients’ DVT risk factors are identified on admission. If an acutely ill hospitalized patient has a major risk factor for DVT or is confined to bed and has one or more additional risk factors, then prophylaxis is recommended.
