Development and Testing of a DVT Risk Assessment Tool: Providing Evidence of Validity and Reliability

Abstract

Nurses can now evaluate patients at risk for DVT or PE using the JFK Medial Center's risk assessment tool.

An evaluation of practice pattern for venous thromboembolism prevention in Lebanese hospitals

“…At the end, the sum of the points constitutes the total VTE risk score, according to which patients were categorized as low, moderate, or high risk. This classification was comparable to that adopted by the ACCP (low, moderate, high, and highest risk), except that patients with the highest risk were merged with the high-risk patient category [23][24][25][26][27]. This score simplified patients' classification by considering the combination of additional factors and then translating them into a total entity, rather than taking each risk alone to categorize patients.…”

“…In addition, trauma during exercise may predispose to the development of DVT immediately after exercise. Most frequent disorders in the order of tendency for DVT development are as follows: factor V Leiden and prothrombin gene mutations, antithrombin protein C or S deficiency, increased factor VIII, factor V Leiden heterozygous mutations, and increased levels of factor VII, factor IX, and factor XI [36]. Hematological analyses of elite players found similar frequencies of hypercoagulopathies with general population [22].…”

Reliability of a point‐based VTE risk assessment tool in the hands of medical residents

“…For instance, one study used 3 trained nurses to employ a similar risk assessment tool, and found an ICC of 0.98 for overall assessments of VTE risk, but did not report protocol adherence. 19 Another study found inter-rater reliability to be high among 5 physician observers (kappa scores of 0.81 and 0.90 for risk stratification and VTE plan, respectively). 18 These two studies evaluated the performance of experienced evaluators who employed different and simpler VTE risk assessment tools.…”

“…The kappa score has been used in other studies to determine inter-rater reliability using similar VTE risk assessment tools. 18,19 Finally, adherence to our hospital's protocol was determined by comparing the residents' VTE plans with the lead author's VTE plans for each of the 21 vignettes. We used SAS 9.1.3 for all statistical analyses (SAS Institute, Cary, NC).…”

“…4,18 To date, several studies have demonstrated that attending physicians and nurses can reliably apply a VTE risk assessment tool, but none that measure how reliably residents can perform this task when using a point-based tool. 18,19 For academic medical centers, information about the reliability of such tools is especially important, since they will often be applied by physicians-intraining, who have limited knowledge and experience with VTE guidelines and risk assessment. The goal of our study, therefore, was to use clinical vignettes to determine the reliability and protocol adherence of medical residents' application of an adapted point-based VTE risk assessment tool, independent of other interventions.…”
