ObjectiveTo describe and evaluate the effects of implementation of a venous thromboembolism (VTE) prophylaxis quality improvement (QI) initiative on a gynecologic oncology service at a single institution. MethodsPrior to 2018, no consensus gynecologic oncology VTE prophylaxis protocol existed at the authors' academic institution. Published, evidence-based guidelines were reviewed to create a standardized VTE risk stratification algorithm. Interventions to improve perioperative heparin administration and sequential compression device (SCD) compliance as well as provider/patient education efforts were introduced in January 2018. Initial efforts included nursing and patient SCD education, internal dissemination of VTE prophylaxis guidelines, and creation of a VTE ‘dashboard’ to track performance. During a second phase, VTE prophylaxis guidelines were reviewed and further refined, non-compliant operative cases reviewed weekly, and guidelines incorporated into the electronic medical record. Performance was measured using Tableau data software (www.tableau.com) and by separately evaluating adherence to the developed guidelines in three retrospective cancer-enriched surgical cohorts (2016–2017, 2018, 2019). ResultsCompared to the baseline period, we observed a reduction in VTE rate during the 2018–2019 VTE QI implementation period from 2.1% (19/905) to 1.0% (20/2015, p = 0.02) among gynecologic oncology inpatients. In the retrospective cancer-enriched cohorts, adherence to evidence based guidelines improved: 31.0% in 2016–2017, 69.1% in 2018, and 82.4% in 2019 (p < 0.001). There were no significant differences in rates of peri-operative blood transfusion, surgical site infections, hematomas, or vaginal cuff dehiscences. ConclusionsImplementation of a robust VTE prophylaxis QI initiative has resulted in improved VTE prophylaxis guideline adherence and higher rates of pre-operative heparin administration.
