Venous thromboembolism (VTE) is a life-threatening postoperative complication that carries high morbidity and mortality for plastic surgery patients. In 2011, the American Society of Plastic Surgeons recommended the adoption of a VTE risk stratification and mitigation; however, successful implementation of VTE prophylaxis protocols has not been well described. To address and reduce the VTE burden at our academic center, a risk assessment protocol was implemented for patients undergoing outpatient plastic surgery procedures.
All patients who received outpatient plastic surgery between August 2018 and July 2019 were eligible for the VTE modified Caprini risk assessment screening. Sampling of practice patterns was done by chart review from the first week of each month. The study was divided into 3 phases to assess the relationship of screening compliance rates with each protocol change. Compliance was defined as completion of VTE Caprini screening with documentation in patients’ charts.
Over the 12-month study period, 277 patients met the inclusion criteria. From August to November 2018 (phase 1), patients were screened at the initial clinic visit with an average compliance rate of 11.1%. In December 2018 (phase 2), patients were screened on the day of surgery, with an average compliance rate of 47.1%. From January to July 2019 (phase 3), surgeons recorded the numerical Caprini score into the patient’s electronic medical record with a subsequent compliance rate of 61.3%. The overall compliance during the 12 months was 44.8%. The median calculated Caprini score for this population was 4 (range, 1-7).
Standardization of VTE risk assessment is vital for patient safety and outcomes. Successful implementation and long-term protocol sustainability are not a simple goal. In this study, protocol compliance greatly improved after tailoring the guidelines to the specific institutional needs and workflow. These results reinforce the importance of continuous protocol review and modification to ensure optimal departmental buy-in and sustainability.
