SOP Bulletin 167

ICD Coding:
  • ICD-9-CM Codes: 798.1, 798.2
  • ICD-10-AM Codes: R96

This SOP is only used when there is no known underlying disease or injury which could account for the client’s death.

Is specific diagnostic evidence required to apply the SOP? - Yes.

This diagnosis is complex and is a diagnosis of exclusion. The contemporary medical documents should be sought, together with the death certificate, and if a coroner’s inquest or autopsy has been performed, these documents should also be sought. The relevant medical specialist would be a pathologist (if there has been an autopsy) or the attending emergency physician.

Are there sub-factors that require specific information? - No.
Diagnoses covered by SOP
  • Any death where an underlying disease or injury could have accounted for the death.
  • Suicide - There is a separate SOP for suicide.
Conditions excluded from SOP
  • Any death where an underlying disease or injury could have accounted for the death
  • Suicide - There is a separate SOP for suicide.
Unconfirmed diagnosis

If, after applying the above information, you are unable to confirm the diagnosis, you should then seek medical officer advice about further investigation.

Comments

The reference to the ‘QT interval’ in the SOP pertains to a measurement of the interval between the Q and the T waves in an electrocardiograph (ECG) tracing of the heart.

Physiological measurements around the time of death can be distorted. Any diagnoses of diabetes mellitus, hypertension or epilepsy need to have been made prior to the death episode.

It is common for chest trauma to occur during cardiopulmonary resuscitation. This is not a ‘blow to the chest immediately before the sudden unexplained death’ but chest trauma after the "onset" of sudden unexplained death as a form of treatment.
