pulmonary thromboembolus secondary to left deep vein thrombosis
AI-generated summary
Darren Templeton, a 51-year-old man with obesity (BMI 31.5), died of pulmonary thromboembolism and left deep vein thrombosis six days after undergoing left knee arthroscopy. Critical clinical lessons: (1) VTE risk assessment forms were not completed on admission despite hospital policy; (2) pharmacological VTE prophylaxis was not provided despite high-risk status (obesity, major orthopaedic surgery); (3) aspirin monotherapy is inadequate for VTE prevention in knee replacement; (4) post-discharge breathlessness was dismissed and not investigated; (5) lack of formal documented VTE risk stratification meant individualised prophylaxis decisions were not reviewed. The coroner could not definitively state that escalated prophylaxis would have prevented death given controversial guidelines, but emphasised that formal documented risk assessment at admission was essential standard practice that failed to occur.

absence of formal pre-operative VTE assessment by orthopaedic surgeon
no pharmacological prophylaxis despite high-risk status

deviation from hospital VTE prevention policy by treating surgeon
Coroner's recommendations
St Vincent's Private Hospital RCA should review their VTE prevention policy and consult orthopaedic surgeons to reach consensus and address wide variations in VTE prophylaxis practices
St Vincent's Private Hospital should ensure completion of VTE prevention policy review in a timely manner with specific completion timeframe established
St Vincent's Private Hospital VTE Prevention Policy should be updated to improve staff adherence to completion and documentation of VTE risk assessment in all hospitalised patients; prescribed management should be clearly documented and supported by evidence-based guidelines; increase staff education on VTE risks in the interim
Victorian Department of Health and Human Services should consider public education campaign to raise awareness of VTE risk and importance of early mobilisation, particularly in people with BMI over 30 who are immobilised or recently discharged from hospital
