What should be listed as the primary cause of death on the death certificate for an adult patient who died from severe drug-induced liver injury complicated by erythroderma and septic shock?

Death Certificate Documentation for Drug-Induced Liver Injury with Erythroderma and Septic Shock

The primary cause of death should be listed as drug-induced liver injury (or acute liver failure secondary to drug-induced hepatotoxicity), with erythroderma and septic shock listed as contributing complications in the causal sequence. 1

Understanding Death Certificate Structure

Death certificates require identification of the underlying cause of death—the disease or injury that initiated the chain of events leading directly to death—rather than just the terminal event 1. In this case:

• Immediate cause of death (Part I, Line a): Septic shock
• Due to (Part I, Line b): Multiorgan failure
• Due to (Part I, Line c): Drug-induced acute liver failure
• Due to (Part I, Line d): Drug-induced hepatotoxicity (specify the implicated drug if identified)
• Other significant conditions (Part II): Erythroderma secondary to drug reaction 1

Rationale for This Approach

Drug-induced liver injury should be identified as the underlying cause because it initiated the pathophysiologic cascade. 2, 3 The ACC/AHA guidelines emphasize that the underlying cause of death, not merely the proximate event, should be documented 1.

Key Clinical Context

• Drug-induced liver injury is a leading cause of drug-induced mortality and represents the primary reason for drug withdrawal from markets 2, 3
• Severe drug-induced liver injury commonly leads to death through renal, cardiopulmonary, or liver failure 1
• The presence of jaundice in drug-induced liver injury signifies severe disease with worse outcomes 3
• Mortality in severe cases approaches 100% when complicated by multiorgan failure 1

Specific Documentation Elements

Identifying the Culprit Drug

If the offending drug has been identified through causality assessment, it must be specifically named on the death certificate. 4, 2 Common implicated agents include:

• Antimicrobials (most common cause worldwide) 3
• Paracetamol/acetaminophen 2, 3
• Non-steroidal anti-inflammatory drugs 2
• Antiepileptic drugs 3
• Herbal remedies 2

Documenting the Erythroderma Component

Erythroderma should be listed as a significant contributing condition rather than the primary cause, as it represents part of the drug reaction syndrome but is not typically the direct cause of death. 5, 6 Erythroderma complicated by multiorgan failure is potentially life-threatening due to skin barrier failure and secondary infections 5, 6.

Septic Shock Documentation

Septic shock should be listed as the immediate cause of death (the final event), as it represents the terminal pathway in this clinical scenario. 1 In patients with liver failure, bacterial infections occur in 60-80% of cases, and sepsis is a recognized cause of death in these patients 1.

Common Pitfalls to Avoid

• Do not list only "septic shock" as the cause of death without the underlying etiology 1—this fails to capture the initiating disease process
• Avoid vague terms like "multiorgan failure" alone 1—specify the underlying cause that led to organ failure
• Do not attribute death solely to erythroderma 5, 6—while serious, it is typically a manifestation of the drug reaction rather than the root cause
• Ensure the causal sequence flows logically 1—each condition should plausibly lead to the next in the chain

Additional Considerations

When multiple drugs were administered, document all potentially implicated agents if the specific culprit cannot be definitively identified. 4 Causality assessment scales like CIOMS/RUCAM may not always identify a single offending drug in cases of sequential exposure 4.

The death certificate should reflect that this was an idiosyncratic drug reaction 2, 3, as most drug-induced liver injury is idiosyncratic rather than dose-dependent (except for paracetamol) 2.
