Acute myocardial infarction complicated by multiple organ failure
AI-generated summary
Ronald William Beaumont, 74, died from acute myocardial infarction complicated by multiple organ failure following a second shoulder washout procedure. Key clinical lessons: (1) Despite inadvertent withholding of dual antiplatelet therapy (aspirin and ticagrelor) before surgery on 6 November 2023, the subsequent NSTEMI was not caused by thrombotic occlusion but by supply-demand mismatch from surgical stress, limiting medication error's causal contribution; (2) Inadequate pre-admission documentation and communication about anticoagulation management created confusion between orthopaedic and cardiology teams; (3) Post-operative wound complications required escalation and washout but earlier intervention unlikely to change outcome; (4) System failures in family communication at critical moments and post-death care pathway compliance. The coroner found no causal link between the medication error and death, emphasizing that routine surgical risks and outcome bias can obscure appropriate clinical processes.

Contributing factors
Acute myocardial infarction (NSTEMI) following second shoulder surgery due to supply-demand mismatch rather than thrombotic occlusion
Multiple organ failure including renal and hepatic dysfunction
Post-operative wound dehiscence and infection
Inadequate pre-admission documentation and medication management communication
Unclear process for out-of-hours direct inpatient admission regarding anticoagulation plan
Inadequate family communication at time of first heart attack
Inadequate post-death care pathway completion on non-palliative ward
Possible contrast-induced nephropathy, acute tubular necrosis, autoimmune renal damage, or antibiotic-associated interstitial nephritis
Coroner's recommendations
Establish clear process for out-of-hours direct inpatient orthopaedic admissions requiring formal history and examination by Hospital Medical Officer or covering specialty HMO, medication charting, and collaborative care plan with on-call registrar, documented in electronic medical record
Communicate admission plan via orthopaedic handover worksheet and to covering overnight/weekend orthopaedic team
Provide education to nursing staff on 5FN ward regarding post-death section of care of the dying pathway, including family communication, next steps information, and bereavement support documentation
Review clinical pathway for Direct Admission Process to clarify home unit responsibilities regarding patient assessment and care plan at admission
Adopt conservative approach to Sentinel Event reporting with use of CAE and Safer Care Victoria hotline/email when doubt exists
Establish clearer and more consistent escalation pathway for Sentinel Event recognition and reporting
Notify all units of 24/7 availability of palliative care advice
Improve communication with families during end-of-life care occurring outside palliative care unit
