3067 Venous thromboembolism prophylaxis: prescribing and deprescribing in frailty patients

Abstract Introduction Venous thromboembolism (VTE) prophylaxis is commonly administered to patients across many hospital settings; however, it can be more challenging to address in frailty patients. These patients are more likely to have contraindications to anticoagulation and be ‘delayed discharges’ (medically fit for discharge and at baseline mobility), at which point VTE prophylaxis may not be indicated. Method This quality improvement project was carried out in the acute geriatric ward at St John’s Hospital. With the aim to improve VTE prophylaxis (appropriately prescribed and deprescribed when delayed discharge) in frailty inpatients by December 2024, through education of medical staff and by creating a Trak proforma. Teaching was provided to ward medical staff and a new delayed discharge Trak proforma was created. This prompted a review of VTE prophylaxis deprescribing when patients were medically fit for discharge. A simultaneous QI project created an admissions proforma which prompted a review of VTE prophylaxis prescribing when a patient was first admitted to the ward. Results Before the intervention, only 58% of patients in Ward 8 had VTE prophylaxis correctly prescribed on admission. Many patients (40%) remained on VTE prophylaxis despite being delayed discharges. A staff survey revealed a higher confidence level around prescribing VTE prophylaxis than deprescribing. Only 44% of staff regularly considered stopping VTE prophylaxis once a patient was a delayed discharge. After the intervention, an increased number of patients (74%) had correct VTE prescriptions on Ward 8 admission (28% improvement). Only 16% of delayed discharge patients remained on VTE prophylaxis (60% improvement). Conclusion This project improved rates of VTE prescribing in patients admitted to an acute frailty ward and deprescription rates in patients where VTE prophylaxis was no longer indicated by prompting regular reviews of these prescriptions. This intervention could be utilised in other departments.
