cardiac and renal failure complicating treatment of infected ischaemic toes resulting from diabetes mellitus
AI-generated summary
Glenn Howard Raphael, 74-year-old admitted for infected ischaemic toe secondary to diabetes mellitus. During his 17-day hospital stay, he developed acute renal failure leading to cardiac arrest and death. Critical failures included: failure to monitor creatinine and gentamicin levels between 9-18 June despite prescribing three nephrotoxic drugs (gentamicin, celecoxib, ramipril). A vascular registrar prescribed gentamicin; a consultant physician subsequently added ramipril on 13 June for cardiac optimisation—laudable long-term thinking but unnecessary given the acute presentation. Creatinine rose dramatically from 0.100 to 0.319 mmol/L undetected over 6 days. Although monitoring failure is clear, whether earlier detection would have prevented death remains uncertain. Key lesson: in acutely unwell patients already on nephrotoxic antibiotics, adding further nephrotoxic agents requires robust concurrent monitoring supervision. Registrars bear primary responsibility for overseeing junior doctor-ordered tests.

failure to monitor creatinine levels between 12 June and 18 June 2001 despite use of three nephrotoxic drugs
failure to monitor serum gentamicin levels after 9 June 2001
addition of ramipril (ACE inhibitor) on 13 June in context of already compromised renal function and concurrent nephrotoxic drugs
inadequate clinical supervision of junior medical staff
absence of registrar oversight of test ordering and result review
high workload of interns with insufficient support
Coroner's recommendations
Implement enhanced monitoring protocols for patients on multiple nephrotoxic drugs, with registrar supervision of junior staff test ordering
Consider deferring non-acute cardiac optimisation medications (such as ACE inhibitors) until after resolution of acute infection and discharge from hospital in patients admitted for acute infection
Establish ward pharmacist involvement in reviewing patients on nephrotoxic drug combinations (as implemented post-2001)
Increase consultant ward round frequency to improve oversight of complex patients
Recruit senior resident support staff to assist interns with workload management
