Effectiveness and safety of inpatient versus extended venous thromboembolism (VTE) prophylaxis with heparin following major pelvic surgery for malignancy: protocol for a systematic review.

ABSTRACT: BACKGROUND:Venous thromboembolism (VTE) is a common postoperative complication associated with significant morbidity and mortality. The use of prophylactic heparin postoperatively reduces this risk, and the use of extended duration prophylaxis is becoming increasingly common. Malignancy and pelvic surgery both independently further increase the risk of postoperative VTE and patients undergoing major pelvic surgery for malignancy are at particularly high risk of VTE. However, the optimum duration of prophylaxis specifically in this population currently remains unclear. METHODS:We will conduct a systematic review of literature in accordance with the Cochrane Handbook for Systematic Reviews of Interventions (Higgins JPT, Green S. Cochrane Handbook for Systematic Reviews of Interventions version 5.1.0.,2011) to evaluate current evidence of the effectiveness and safety of inpatient versus extended VTE prophylaxis with heparin (all forms) following major pelvic surgery for malignancy. We will search PubMed, EMBASE, and the Cochrane Library. Regarding safety, Food and Drug Administration (FDA), and Therapeutic Goods Administration (TGA) websites will be searched, including all levels of evidence. Results will be the postoperative timeframe in which a VTE event can be considered to have been provoked by the surgery, and the number of patients needed to treat with both inpatient and extended prophylaxis to prevent a VTE event in this timeframe, comparing these to determine if there is a significant benefit from extended prophylaxis. DISCUSSION:This systematic review will aim to identify the postoperative period in which patients undergoing major pelvic surgery for malignancy are at further increased risk of VTE as a result of their surgery and the optimum duration of heparin VTE prophylaxis with heparin to reduce this risk. Determining this will allow evidence-based recommendations to be made for the optimum duration of heparin VTE prophylaxis post major pelvic surgery for malignancy, leading to improved standards of care that are consistent between different providers and institutions. SYSTEMATIC REVIEW REGISTRATION:In accordance with guidelines, our systematic review was submitted to PROSPERO for consideration of registration on 16/12/17 and was registered on 12/1/18 with the registration number CRD42018068961 , and it was last updated on December 1, 2018.

Project description:Extended venous thromboembolism prophylaxis (EVTEP) with low-molecular weight heparin such as enoxaparin for 28 days following surgery for cancer significantly reduces venous thromboembolic events compared to a standard 6-10 day course. National Institute of Clinical Excellence (NICE) guidelines suggest EVTEP should be offered to patients undergoing colorectal cancer surgery. Local EVTEP prescribing and monitoring guidelines in a busy inner city teaching hospital colorectal surgery unit, were devised to ensure NICE guidelines are followed. Adherence to local EVTEP guidelines was recorded through a retrospective audit of patients undergoing elective colorectal cancer surgery during February 2011 (n=19). Prospective re-audit cycles were undertaken during April-May (n=17) and September-December 2012 (n=17). The first audit cycle revealed that overall standards were not being met with just 11% of 'at risk' patients being correctly identified in pre-operative assessment clinic and continued low adherence to guidelines on the ward with only 44% of patients being prescribed EVTEP at discharge. Following each audit cycle, educational interventions were directed towards the multi-disciplinary team involved in the care of patients undergoing colorectal cancer surgery. This involved education of the team members regarding EVTEP, presentation of the audit results with instruction for improvement. Results of the second and third audit cycles showed improvements in guideline adherence with 100% of patients in these cohorts having been prescribed EVTEP at discharge. Marked improvements were also seen in the correct identification of 'at risk' patients, patient education in pre-operative assessment clinic, and warning of potential side-effects. This project has shown a significant global improvement in EVTEP-related patient care and adherence to local guidelines following education of the multi-disciplinary team involved, which consequently reduced the risk of venous thromboembolism within this patient cohort.
