Cause of death

cardiac arrhythmia secondary to prolongation of the QT interval

AI-generated summary

NL, a 62-year-old man with schizoaffective disorder and hypothyroidism, died of cardiac arrhythmia secondary to QT prolongation while an involuntary mental health inpatient. He had a known history of non-compliance with thyroxine medication. Thyroid function tests on 5 April 2019 revealed severely elevated TSH (92.7) and low thyroxine (1.6), suggesting non-compliance, but these critical results were not appropriately reviewed or actioned. A registrar endorsed the results without clinical assessment, and they were not discussed at a multidisciplinary team meeting despite prior plans to do so. Nursing observations on the night of death were inadequate—chest movement was likely mimicked by breeze through an open window rather than actual respiration. Key lessons: pathology results require active clinical review not passive endorsement; abnormal results must trigger discussion at team meetings; psychiatric units managing medically complex patients need robust systems to ensure medical escalation; observation charts must document actual respiration rates, not estimated movement.

Contributing factors

  • recurrent hypothyroidism due to non-compliance with thyroxine
  • probable hypothyroidism-induced dilated cardiomyopathy
  • antipsychotic therapy
  • elevated body mass index
  • marijuana use
  • possible sleep apnoea
  • failure to review thyroid function test results of 5 April 2019
  • inadequate nursing observations overnight
  • absence of clinical escalation of abnormal pathology results

Coroner's recommendations

  1. Request escalation to relevant State entity for changes to eMR to ensure test results are not checked as endorsed by default, and instead require clinicians to manually endorse each result
  2. Follow up previous requests to amend eMR Copy and Pasting procedure to include a warning of dangers associated with copying and pasting information in eMR
  3. Review nursing model of care at Kiloh Centre to determine whether staffing numbers, patient-to-nurse ratios, and allocation of clinical responsibilities are sufficient to meet patient loads and ensure patient safety
