Venous Thromboembolism (VTE) is a known complication of hospitalization, frequently extending the length of stay and increasing hospital mortality (Maynard, 2016). Approximately 20% of VTE are associated with a surgical procedure (Henke et al., 2020). Almost all hospitalized patients have at least one risk factor for VTE, and approximately 40% have three or more risk factors. Without thromboprophylaxis, the incidence of objectively confirmed, hospital-acquired deep-vein thrombosis (DVT) is approximately 10% to 40% among medical or general surgical patients and 40% to 60% following major orthopedic surgery (Geerts et al., 2008). Commonly, criteria for admission to the Intensive Care Unit (ICU) itself puts patients at an increased risk for developing VTE and subsequent increased risk of morbidity from pulmonary embolism (PE). Some risk factors are related to the acute illness present that allowed for the admission to the ICU unit, and some risk factors may be acquired during the ICU admission due to subsequent medical treatments, for example limitations of mobility, presence of central venous lines or mechanical ventilation and subsequent pharmacological paralysis. Reports of DVT in the population of ICU patients vary in relation to the acuity of the illness in this population. DVT in ICU patients diagnosed with routine venography or Doppler ultrasound found ranges between 10% to 100%. Five studies prospectively screened patients who were not receiving thromboprophylaxis during their ICU stays. The rates of DVT using Fibrinogen Uptake Test, Doppler Ultrasound or venography ranged from 13 to 31% (Geerts et al., 2008). It is essential for all ICUs to assess each patient upon admission to the ICU unit, a change in level of status, for the need for VTE prophylaxis due to the above increased development of risk factors (Geerts et al., 2004). American Society of Hematology (ASH) 2018 VTE prophylaxis guidelines strongly recommend pharmacological prophylaxis using unfractionated heparin (UFH), low molecular weight heparin (LMWH) or fondaparinux for acutely and critically ill hospitalized medical patients, unless contraindicated. The use of mechanical prophylaxis is an acceptable alternative for patients with increased risk of bleeding and preferred over no prophylaxis. ASH 2019 guidelines for surgical patients similarly recommend pharmacological or mechanical prophylaxis over no VTE prophylaxis. Some select surgeries have previously been monitored in the Surgical Care Improvement Project; since performance on these surgeries has achieved very high levels, they are not included in this measure. |

| Clinical Recommendation Statement | *See CMS190v10.html | *See CMS190v11.html |
Failure to recognize and protect patients at risk for venous thromboembolism (VTE) increases the chances for critically ill hospitalized patients for developing a deep vein thrombosis or dying from a pulmonary embolism. Screening all patients is the only evidence based practice in reducing incidence of disease. All intensive care unit (ICU) patients should be evaluated for primary VTE prophylaxis, and given appropriate prophylaxis when indicated. |

| Guidance |
The definition of an ICU for the purpose of the measures noted above is that used by the CDC in the NHSN Patient Safety Project. An intensive care unit can be defined as a nursing care area that provides intensive observation, diagnosis, and therapeutic procedures for adults and/or children who are critically ill. An ICU excludes nursing areas that provide step-down, intermediate care or telemetry only and specialty care areas. Reasons for no pharmacological and no mechanical VTE prophylaxis must be explicitly documented by the MD/APN/PA or pharmacist and linked with VTE prophylaxis. Ambulation alone is not a sufficient reason for not administering VTE prophylaxis. In order for ambulation/patient ambulating to be considered as an acceptable reason, there needs to be explicit documentation, e.g., "patient out of bed and ambulating in halls - no VTE prophylaxis needed." This eCQM is an episode-based measure. An episode is defined as each inpatient hospitalization or encounter that ends during the measurement period. This version of the eCQM uses QDM version 5.5. Please refer to the eCQI resource center for more information on the QDM. |
