AI-generated summary

David Paul Unwin, a 55-year-old kidney transplant recipient with polycystic kidney disease, died of sepsis in January 2017. He presented with progressive symptoms including chronic diarrhoea, weight loss (16kg in 8 weeks), a gluteal abscess, nausea, vomiting, and deteriorating renal function (creatinine rising from 180 to 381 micromoles/L). Critical failures included: delayed colonoscopy (referred May 2016, not performed by death), infrequent specialist review (one visit in 9 months versus recommended three-monthly), failure to hospitalise despite critical blood results on 6 January, and poor communication between primary care and specialist. When critical pathology results were received on 6 January, the renal physician decided to defer action until the scheduled appointment on 11 January, a decision the coroner found regrettable. The patient died before that appointment. Immunosuppressed transplant patients require close monitoring, prompt investigation of deterioration, and coordinated multidisciplinary care.

Contributing factors

  • failure to ensure timely colonoscopy despite positive faecal occult blood testing and persistent diarrhoea
  • inadequate frequency of specialist review (one visit in 9 months versus recommended three-monthly)
  • failure to hospitalise patient in mid-December 2016 despite presentation with abscess, nausea, vomiting, weight loss, diarrhoea and significantly elevated creatinine
  • failure to ensure hospitalisation on 6 January 2017 when critical blood results showed creatinine of 381 micromoles/L
  • delayed recognition of critical pathology results at general practice (not sighted until 10 January)
  • poor communication between Dr Gbenimacho and Dr Mathew regarding patient's full clinical picture
  • Dr Mathew's underestimation of illness severity and assumption that cellulitis would resolve without comprehensive investigation
  • lack of holistic approach to immunosuppressed patient's complex presentation

Coroner's recommendations

  1. GTMC and other general practices in Tasmania should carry out a review of their practices and procedures around the sighting of pathology results with a view to ensuring that those results which require an urgent response do not 'fall through the cracks' and are seen and responded to at the earliest opportunity
