acute renal failure with associated severe acidosis and hyperkalemia

AI-generated summary

A 67-year-old Aboriginal male with dementia was discharged from Royal Darwin Hospital on 4 November 2001 following cystoscopy and bladder neck incision for suspected obstruction. Critical communication failures meant the treating surgeon was not informed of rising creatinine levels (27 Oct and 1 Nov results showing worsening renal function) which would have prevented discharge. The ultrasound request lacked 'post void' specification, leading to misinterpretation of anuria as successful voiding. Discharge planning was inadequate: no escort was arranged despite documented dementia, the patient was sent home by bus in hospital pyjamas, and a critical medical discharge summary was not prepared until 18 days post-discharge. The patient was found alone under a tree in Katherine. He returned to hospital on 25 November and died of acute renal failure with severe acidosis and hyperkalemia on 26 November 2001. The premature discharge likely shortened his lifespan. Key lessons: ensure test results reach senior clinicians; specify clinical intent in radiology requests; consider cognitive and social vulnerability in discharge planning; involve renal specialists early in declining renal function; and provide written discharge orders with explicit post-discharge care instructions.

Contributing factors

  • failure to communicate rising creatinine levels to treating surgeon
  • inadequate ultrasound request specification ('post void' not included)
  • misinterpretation of ultrasound findings as successful voiding rather than anuria
  • failure to involve renal team despite deteriorating renal function
  • inadequate discharge planning with no escort arranged
  • premature discharge without written discharge summary
  • failure to consider dementia and cross-cultural communication needs in discharge decision
  • patient sent home by bus alone in hospital pyjamas without notification to family
  • delayed preparation and circulation of medical discharge summary (18 days post-discharge)
  • excessive junior medical staff workload and lack of technological support

Coroner's recommendations

  1. RDH to continue reviewing and enhancing admission and discharge procedures, including implementation of procedures for admission under multiple medical teams
  2. Implement technological fail-safe systems to support discharge planning in the absence of reliance on human communication alone
  3. Introduce procedures ensuring all patients with moderate to advanced chronic renal insufficiency are notified to and reviewed by the renal team prior to discharge
  4. Require medical personnel to order patient discharges in writing in patient records with clear specification of all post-discharge care
  5. RDH to implement procedures facilitating timely completion and circulation of medical discharge summaries to relevant medical organisations
