Abstract

Background:
Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in hospitalized patients. Numerous VTE prevention clinical practice guidelines are available but not consistently implemented. This systematic review explored effectiveness of implementing VTE prevention clinical practice guidelines on VTE risk assessment and appropriateness of prophylaxis in hospitalized adult medical patients and identified the interventions followed to improve the adherence to these guidelines.

Methods:
Six electronic databases were searched for Randomized Controlled trials; Clinical controlled trials or pre/post evaluation studies up to January 2019. Studies identified were screened for eligibility by two reviewers independently. Data were extracted by two reviewers using a standardized form. Risk of bias was assessed using MINORS and the certainty of evidence for each outcome using the GRADE approach.

Results:
Of the 3,537 records identified, 36 were eligible; eight studies were included for qualitative synthesis and four for meta‐analysis. The meta-analysis of the studies assessing the impact of implementing VTE clinical practice guidelines favoured appropriate prophylaxis (RR 1.67, 95% CI 1.41 to 1.97, 552 patients). Potential risk of bias was assessed to be low for 28% of the studies. However, using GRADE, the certainty of the evidence of all outcomes was rated very low quality.

Conclusions:
The lack of randomized controlled trials in this area reduces the quality of the evidence available. The evidence from before-after studies suggests that the implementation of VTE clinical practice guidelines may increase the practice of VTE risk assessment and appropriate prophylaxis in hospitalized medical patients.
