Preventing Venous Thromboembolism and Improving the Safety of Anticoagulation Therapy

Objectives: • Describe the impact of Venous Thromboembolism (Safe

Practice 28) complications as it relates to the nation's healthcare patient population.

• Prepare for pay for performance requirements and review national measures.

• Describe the requirements for the Joint Commission National Patient Safety Goal 3E and Anticoagulation Therapy (Safe Practice 29).

• Discuss strategy and stepwise process for planning, design, and implementation of an inpatient anticoagulant service.

Page 9: 1 © 2008 TMIT Dale Bratzler, DO, MPH Michael Gulseth, PharmD, BCPS Dan Ford Hayley Burgess, PharmD, BCPP Charles Denham, MD Preventing Venous Thromboembolism

9© 2008 TMIT

Safe Practice 28: Reduce the occurrence of venous thromboembolism

Safe Practice• Evaluate each patient upon admission, and regularly

thereafter, for the risk of developing VTE/DVT. Utilize clinically appropriate, evidence-based methods of thromboprophylaxis.

Additional Specifications• Document the VTE risk assessment and prevention plan in

the patient’s record.• Explicit organizational policies and procedures should be in

place for the prevention of VTE.Applicable Clinical Care Settings• Short and long-term acute care hospitals, long-term care

facilities, and nursing homes.

Page 10: 1 © 2008 TMIT Dale Bratzler, DO, MPH Michael Gulseth, PharmD, BCPS Dan Ford Hayley Burgess, PharmD, BCPP Charles Denham, MD Preventing Venous Thromboembolism

10© 2008 TMIT

Safe Practice 29: Ensure that long-term antithrombotic (anticoagulation) therapy is effective and safe

Safe PracticeEvery patient on long-term oral anticoagulants should be monitored

by a qualified health professional using a careful strategy to ensure an appropriate intensity of supervision.

Additional Specifications

• Explicit organizational policies and procedures should be in place regarding antithrombotic services that include at least documentation of:• indication for long-term anticoagulation;• target INR range;• duration of long-term anticoagulation and/or a review date;• a longitudinal record of INR values and warfarin doses; and• timing of the next INR appointment.

Applicable Clinical Care Settings

• This practice is applicable in all care settings

Prevention of Venous Thromboembolism

• Recent estimates show that– more than 900,000 Americans suffer VTE

each year• about 400,000 of these being DVT• About 500,000 being manifest as PE

– In about 300,000 cases, PE proves fatal; it is the third most common cause of hospital-related deaths in the United States.

Heit JA, Cohen AT, Anderson FA on behalf of the VTE Impact Assessment Group. [Abstract] American Society of Hematology Annual Meeting, 2005.

Is pulmonary embolism the most common cause of death in the US?

Prevention of Venous ThromboembolismIntroduction

• VTE Remains a major health problem– In addition to the risk of sudden death

• 30% of survivors develop recurrent VTE within 10 years

• 28% of survivors develop venous stasis syndrome within 20 years

– Incidence increases with age

Prevention of Venous Thromboembolism

• The majority (93%) of estimated VTE-related deaths in the US were due to sudden, fatal PE (34%) or followed undiagnosed VTE (59%)

Heit JA, Cohen AT, Anderson FA on behalf of the VTE Impact Assessment Group. [Abstract] American Society of Hematology Annual Meeting, 2005.

For many patients, the first symptom of VTE is sudden death!

How many of those patients with sudden death in the hospital or after discharge attributed to an acute coronary

event actually died of acute pulmonary embolism?

National Body Position Statements

• Leapfrog1:

PE is “the most common preventable cause of hospital death in the United States”

• Agency for Healthcare Research and Quality (AHRQ)2:

Thromboprophylaxis is the number 1 patient safety practice

• American Public Health Association (APHA)3:

“The disconnect between evidence and execution as it relates to DVT prevention amounts to a public health crisis.”

Medical “Injuries” During Hospitalization

Postoperative DVT or PE:• 2nd commonest medical “injury” overall

• 2nd commonest cause of excess length of stay

• 3rd commonest cause of excess mortality

• 3rd commonest cause of excess charges

Annual cost to treat VTE

• $11,000 per DVT episode per patient• $17,000 per PE episode per patient• Recurrence increases hospitalization costs

by 20%• Complications of anticoagulation• Time lost from work

– Quality of life: venous stasis and pulmonary HTN

Risk Factors for VTE

• Previous venous thromboembolism

• Increased age

• Surgery

• Trauma - major, local leg

• Immobilization - ? bedrest, stroke, paralysis

• Malignancy & its Rx (CTX, RTX, hormonal)

• Heart or respiratory failure

• Estrogen use, pregnancy, postpartum

• Central venous lines

• Thrombophilic abnormalities

Most hospitalized patients have at

least one additional risk factor fo

r

VTE

Therefore, most patients in the hospital need VTE prophylaxis!

Benefit: risk favors routine prophylaxis

• Major orthopedic surgery

(THR, TKR, HFS)

• Major trauma

• Spinal cord injury

• Major general, gyne, urologic surgery

• Major neurosurgery

• Medical patients with additional risk factors

• Most ICU patients

Benefit: risk uncertain- local practice or

individual prophyl.

• Laparoscopic surgery

• Vascular surgery

• Cardiac surgery

• Elective spine surgery

• Arthroscopic surgery

• Burns

• Isolated lower extremity fracture

Benefit: risk favors no prophylaxis

• Surgical patients:

- brief duration

- fully mobile

- no additional RFs

• Medical patients:

- fully mobile

- no additional RFs

• Long distance travel

Prevention of Venous ThromboembolismLow-, moderate-, or high-risk

Focus of New Measures

How many of these patients do we actually

admit to the hospital anymore?

Page 28: 1 © 2008 TMIT Dale Bratzler, DO, MPH Michael Gulseth, PharmD, BCPS Dan Ford Hayley Burgess, PharmD, BCPP Charles Denham, MD Preventing Venous Thromboembolism

28

Prophylaxis Modalities

• Mechanical– Graduated compression stockings (GCS) (e.g., “white

hose”)– Sequential compression devices

• Venous foot pumps (currently recommended only for orthopedic surgery in patients with bleeding risk)

In most studies, less effective than pharmacologic prophylaxis and patient

compliance rates are generally low.

Rates of compliance with mechanical forms of prophylaxis in many studies is less than 50% - has become a new target

of malpractice litigation.

Pharmacologic Prophylaxis

• Low-dose unfractionated heparin (LDUH)

• Low-molecular weight heparin (LMWH)

• Fondaparinux

• Warfarin

to Prevent and Treat VTE

Page 31: 1 © 2008 TMIT Dale Bratzler, DO, MPH Michael Gulseth, PharmD, BCPS Dan Ford Hayley Burgess, PharmD, BCPP Charles Denham, MD Preventing Venous Thromboembolism

31

Why the need for performance measures?

• Despite widespread publication and dissemination of guidelines, practices have not changed at an acceptable pace– There are still far too many needless deaths

from VTE in the US

• Reasonably good evidence that using performance measures for accountability can accelerate the rate of change

7 Refined Measures Recommended for Endorsement by Steering Committee

• Risk Assessment/Prophylaxis domain• Prophylaxis w/in 24 hours of admission or

surgery, OR a documented risk assessment showing that the patient does not need prophylaxis

• Prophylaxis/documentation w/in 24 hours after ICU admission or surgery

Discards any “requirement” for a documented risk assessment – allows programs of default prophylaxis.

41

7 Refined Measures Recommended for Endorsement by Steering Committee

• Treatment and Monitoring domain• IVC filter appropriate indication

• Documented acute VTE with a contraindication to anticoagulation; or chronic thromboembolic pulmonary hypertension

• Measure recommended for quality improvement only

• Patients w/overlap of anticoagulation therapy• At least five calendar days of overlap and discharge

with INR > 2.0, or discharge on overlap therapy

• Patient receiving UFH with dosage/platelet count monitoring by protocol/nomogram

• Nomogram/protocol incorporates routine platelet count monitoring+

42

7 Refined Measures Recommended (cont.)

• Treatment/Monitoring Domain (cont.)

• Discharge instructions consistent with Joint Commission safety goals (Follow-up Monitoring, Compliance Issues, Dietary Restrictions, Potential for Adverse Drug Reactions/Interactions)

• Outcome• Incidence of potentially-preventable VTE – proportion

of patients with hospital-acquired VTE who had NOT received VTE prophylaxis prior to the event

• Incorporate the new “present on admission” codes

Page 43: 1 © 2008 TMIT Dale Bratzler, DO, MPH Michael Gulseth, PharmD, BCPS Dan Ford Hayley Burgess, PharmD, BCPP Charles Denham, MD Preventing Venous Thromboembolism

43

Strategies to Improve VTE Prophylaxis

• Hospital policy of risk assessment for all admitted patients??– Most will have risk factors for VTE and should

receive prophylaxis– Preprinted protocols for surgical patients– Electronic reminders (Kucher – NEJM 2005;352:969)

– Default prophylaxis (opt out)

No individual risk assessment protocol has ever been validated in a clinical trial. While it seems intuitive that more points equates to greater risk of VTE, that has never been proven in a study, and we certainly have no idea if you need more prophylaxis for more points!

Should VTE prophylaxis be the default

for all hospitalized patients?

Summary

• VTE is very common, often unrecognized, and a common cause of hospital morbidity and death

• The vast majority of hospitalized patients are at risk for VTE

• New national performance measures will focus on evidence-based prevention and treatment of VTE

If your organization is serious about Patient Safety, you have to address VTE prevention and treatment!

Safe Practice 29

• Every patient on long-term oral anticoagulants should be monitored by a qualified health professional using a careful strategy to ensure an appropriate intensity of supervision.

Page 52: 1 © 2008 TMIT Dale Bratzler, DO, MPH Michael Gulseth, PharmD, BCPS Dan Ford Hayley Burgess, PharmD, BCPP Charles Denham, MD Preventing Venous Thromboembolism

52© 2008 TMIT

Policies and Procedures Should Require Documentation of:

• Indication for long-term anticoagulation

• Target INR range

• Duration of long-term anticoagulation and/or a review date

• A longitudinal record of INR values and warfarin doses

• Timing of the next INR appointment

Joint Commission NPSG 3E Rationale

• Anticoagulation is a high risk treatment, which commonly leads to adverse drug event due to the complexity of dosing these medications, monitoring their effects, and ensuring patient compliance with outpatient therapy. The use of standardized practices that include patient involvement can reduce the risk of adverse drug events associated with the use of heparin (unfractionated), low molecular weight heparin (LMWH), warfarin, and other anticoagulants.

Implementation Expectations

• The organization implements a defined anticoagulant management program to individualize the care provided to each patient receiving anticoagulant therapy.

• To reduce compounding and labeling errors, the organization uses ONLY oral unit dose products and pre-mixed infusions, when these products are available.

• When pharmacy services are provided by the organization, warfarin is dispensed for each patient in accordance with established monitoring procedures.

• The organization uses approved protocols for the initiation and maintenance of anticoagulation therapy appropriate to the medication used, to the condition being treated, and to the potential for drug interactions.

56© 2008 TMIT

Implementation Expectations

• For patients being started on warfarin, a baseline International Normalized Ratio (INR) is available, and for all patients receiving warfarin therapy, a current INR is available and is used to monitor and adjust therapy.

• When dietary services are provided by the organization, the service is notified of all patients receiving warfarin and responds according to its established food/drug interaction program.

• When heparin is administered intravenously and continuously, the organization uses programmable infusion pumps.

Implementation Expectations

• The organization has a policy that addresses baseline and ongoing laboratories tests that are required for heparin and low molecular weight heparin therapies.

• The organization provides education regarding anticoagulation therapy to prescribers, staff, patients, and families.

• Patient/family education includes the importance of follow-up monitoring, compliance issues, dietary restrictions, and potential for adverse drug reactions and interactions.

• The organization evaluates anticoagulation safety practices.

Roles of the Inpatient Anticoagulation Program

• Providing anticoagulant dosing– Dosing heparin, LMWH, warfarin, argatroban, etc.

• Assuring regular monitoring and patient evaluation– Designing policies to assure coagulation labs are drawn when

needed; consulting on individual patients

• Provision of repeated patient education– Assuring hospital education on warfarin, LMWH, etc.

• Communicating with other patient care providers that are involved in the patient’s care– Helping surgeons and hospitalists communicate regarding the

risks vs. benefits of therapy and picking the right option

• Meeting transitional care needs

59© 2008 TMIT

Roles of the Inpatient Anticoagulation Program

• Helping with changes from heparin to LMWH and vice versa

• Setting up short stay/outpatient VTE treatment programs• Assuring the systematic prophylaxis of VTE• Evaluating available anticoagulant products for formulary

– Not just about cost• Assuring smooth transitions in care• Assisting in determining the appropriateness of care

– Picking the right parenteral antithrombin agent for the disease, renal function, patient history, etc.

• Evaluating the safety of the dispensing and administration procedures used by the facility

• And many more…..

So how do you get there?

• The organization implements a defined anticoagulant management program to individualize the care provided to each patient receiving anticoagulant therapy.– Identify a qualified professional and start an

anticoagulation program that covers both outpatients and inpatients

– Also use that leader to evaluate and improve other practices to assure the safety of anticoagulant use

– Where do you start?

Step 1: Review the literature and network with others

• Take a close look at the articles already presented– Which hospitals seem similar to your situation?– Which articles deal with issue that your hospital is

struggling with?• Closely evaluate the Bond and Raehl article

– Can be used to postulate a financial benefit to the hospital

• Talk to colleagues at other hospitals who have services like you are contemplating– Site visits are a very good idea to see a service first

Step 2: Plan the Anticoagulation Service

• Successful programs will have support from:– Pharmacy– Medical staff– Hospital administration– Nursing

• Think about things from their perspective and assure those issues are addressed

68© 2008 TMIT

Step 3: Gain Formal Approval of the Program

• The pharmacy and therapeutics committee will likely need to approve all programs, protocols, and guidelines– What policies and procedures are needed?

69© 2008 TMIT

Step 4: Launch the Program and Address Unanticipated Issues

• Be sure to do careful planning prior to launch, but

• Be careful not to “over plan”– Not having the service in place could be the

bigger issue– Piloting is an excellent way to avoid this

• Once “bugs” are worked out, expand to other areas

70© 2008 TMIT

Step 5: Monitor Program Quality and Strive for Improvement

• Don’t let quality issues go– Address system issues that need to be

addressed– Provide individual, one on one, feedback

when individual pharmacists do not perform adequately and strive to improve their skills

• Be sure to credit your staff when care is improved

Step 6: Expand into New Arenas as the Patient Need Arises

• Look for the next opportunity to improve care

• What is the department’s role with rVIIa?• How is vitamin K being utilized?• Is an inpatient “antithrombosis” program

the next step?
