Preventing H-A VTE Toolkit
- Focuses on the basics of quality improvement.
- Physician driven QI effort.
- Though development of VTE risk assessment and order sets, preventable H-A VTEs have dropped.
- Developed based on the research of Dr. Gregory Maynard, in association with the Society of Hospital Medicine.
Slide 3
VTE Toolkit
- Comprehensive guide that focuses on the basics of quality improvement.
- Step-by-step instructions on the development and implementation of an improved VTE prevention protocol.
- Hierarchy of Reliability.
- Provides sample VTE protocol:
- 3-bucket risk assessment (low, moderate, and high risk).
- Sample order set.
- Measurement strategy for continuous improvement.
Protocol = Risk assessment and corresponding order set of pharmacological agents and/or mechanical prophylaxis.
Slide 4
Toolkit Applicability
- VTE toolkit is usable in varying provider settings:
- Large hospital settings.
- Smaller community hospitals.
- Critical Access Hospitals.
- Usable toolkit for providers that are:
- Have EHR.
- Paper medical record.
- Hybrid (both EHR and paper).
Slide 5
VTE Toolkit Contents
- Taking the Essential First Steps.
- Laying Out the Evidence and Identify Best Practices.
- Analyzing Care Delivery.
- Tracking Performance with Metrics.
- Layering Interventions.
- Continuing to Improve.
Slide 6
VTE Toolkit Layer Interventions
- The VTE protocol serves as the main intervention and focal point for the improvement project:
- Keep the protocol simple.
- Do not interrupt workflow.
- Design reliability into the process.
- Pilot interventions on a small scale before attempting wide scale implementation.
- Monitor use of the protocol.
Protocol = Risk assessment and corresponding order set of pharmacological agents and/or mechanical prophylaxis.

Hierarchy of Reliability
| Level | Predicted Prophylaxis Rate % |
|---|---|
| 1 No protocol (i.e. "state of nature") | 40 |
| 2 Decision support exists but not linked to order writing or prompts exist within orders but no decision support at hand | 50 |
| 3 Protocol well-integrated into orders at point of cre | 65-85 |
| 4 Protocol enhanced by other QI and high-reliability strategies | 80-90 |
| 5 Oversights identified and addressed in real time | 95+ |
Slide 11
Situational Awareness and "Measure-vention"— Getting to 95%
- Identify patients on no anticoagulation.
- Empower nurses to place mechanical prophylaxis.
- Contact MD if no anticoagulant in place and no obvious contraindication:
- Template note, text page, etc.
- Back up these interventions:
- Physicians can not "shoot the messenger."

Slide 12
Making the Right Thing to Do...
- ...The easy thing to do:
- The desired action is the default action (i.e., not doing the desired action requires opting out).
- The desired action is prompted by a reminder or a decision aide.
- The desired action is standardized into a process.
- The desired action is scheduled to occur at known intervals.
- Responsibilities for desired action are redundant.
- If designed well, the VTE protocol will be an intervention.
Slide 13
VTE Levels of Risk
| Levels of Risk | DVT Risk Without Prophylaxis | Suggested Options |
|---|---|---|
Low risk
| <10 % |
|
Moderate risk
| 10-40% |
|
High risk
| 40-80% |

ACCP VTE Prophylaxis Guidelines 8th Edition
- Every hospital should develop formal strategy to prevent VTE.
- Do not use aspirin alone for prophylaxis.
- Use mechanical prophylaxis primarily for patients at high bleeding risk or as an adjunct to pharmacologic prophylaxis.
- Give thromboprophylaxis for:
- Major trauma.
- Spinal cord injury.
- Acute medical illness.
- Most ICU patients.
- Moderate and high risk surgery.

Slide 16
VTE Prophylaxis: Effective, Safe, and Cost-Effective
- Pharmacologic prophylaxis substantially reduces the risk for VTE:
- Symptomatic and asymptomatic VTE reduced.
- Bleeding complications are rare.
- HIT is a serious complication of heparin therapy.
- Cost-effectiveness of VTE prophylaxis well documented.
Slide 17
Barriers to Reducing VTE Risk
- Belief that VTE incidence has declined.
- VTE not perceived as important.
- Lack of familiarity with guidelines.
- Underestimation of thrombotic risk.
- Overestimation of bleeding risk.
- Translation of complicated guidance into simple orders.
- Institutional / structural.
Slide 18
Barriers to Reducing VTE Risk
- Implementation of protocol is flawed.
- Order set not user friendly.
- Process creates duplicate work for physicians.
- Protocol does not fit individual patient.
- Competing order sets.
Slide 19
VTE Impact Case Study Year 1 Provider
Madison Memorial Hospital (MMH) in Rexburg, Idaho developed and implemented a standardized VTE protocol for all hospital admissions based on the recommendations presented in the toolkit. VTE incidence of hospital-associated VTE per 1000 patient days has decreased from a rate of 1.30 to 0.18, an 86% relative improvement, between baseline (4/09-2/10) and remeasurement periods (3/10-11/10). According to team leaders, there also has been significant qualitative impact to their hospital culture and quality performance as a result of the changes made to the VTE protocol: they have implemented the first standardized best practice protocol.
Slide 20
VTE Impact Case Study Year 2 Provider
A New Mexico hospital entered the project without a VTE protocol in place. As a result of participating in the project, the facility developed a protocol consistent with the toolkit to include a three-level risk-stratified assessment linked to treatment options. The hospital aggressively pursued improvement of its VTE protocol by developing, approving, and implementing a new VTE protocol hospital-wide in less than one month after attending the initial learning session. As a result, compliance with physician use of the protocol is 100 percent, with prevalence of appropriate VTE prophylaxis increasing from 33 to 75 percent between March and July 2011. The facility is now implementing "measure-vention"—concurrent review and interventions of patients in real time—to continue to foster improvement in the prevalence of appropriate VTE prophylaxis.
Slide 21
VTE Impact Case Study Year 2 Provider
When Memorial Health Care Systems in Seward, Nebraska began the collaborative, Hank Newburn, MD, Family Practice Physician explains, "When we joined the VTE Collaboration in February 2011 Memorial Health Care Systems did not have a risk assessment tool, or protocols for interventions in place. We completed the risk assessment tool which models Dr. Gregory Maynard's recommendations. Since the inception of the project, we have realized a 5% increase in VTE prophylaxis due to heightening the awareness. I anticipate a significant percentage increase after implementation due to the availability of a consistent risk assessment process, and protocols for interventions. This project has provided great direction for the development of our VTE tools, which will aid us in providing best practice for VTE prophylaxis consistently, promoting increased safety for our patients."
Slide 22
Key Points Expert Recommendations
- VTE protocols embedded in order sets.
- Simple risk stratification schema, based on VTE-risk groups (2-3 levels of risk should do it).
- Institution-wide if possible (a few carve outs ok).
- Local modification is OK:
- Details in gray areas not that important.
- Use "measure-vention" to accelerate improvement.
