Identification and Prognostication of End-of-Life State Using a Japanese Guideline-Based Diagnostic Method: A...

Area of Science:

• Gerontology and Palliative Care
• Medical Diagnostics and Prognostics

Background:

• Prognostic uncertainty poses a significant barrier to timely and effective palliative care delivery.
• Accurate estimation of prognosis for patients nearing the end of life is a complex clinical challenge.

Purpose of the Study:

• To evaluate the diagnostic accuracy of a unique end-of-life diagnostic method.
• To assess the method's utility in improving prognostic estimation for palliative care.

Main Methods:

• Retrospective longitudinal observational study in a rural Japanese super-aged community.
• Utilized a unique end-of-life diagnostic process involving physician judgment, patient disclosure, and end-of-life case conferences (EOL-CC).
• Analyzed mortality within 6 months post-EOL-CC decision for 315 patients (median age 89).

Main Results:

• End-of-life (EOL) diagnosis was associated with a significantly lower 6-month survival rate (6.9%) compared to non-EOL diagnosis (43.5%; P < 0.001).
• The EOL-diagnosis demonstrated high sensitivity (0.95) and a high diagnostic odds ratio (10.32).
• Specificity for EOL-diagnosis was low (0.35).

Conclusions:

• The diagnostic process, based on Japanese end-of-life guidelines, offers tolerable accuracy for identifying and prognosticating end-of-life patients.
• The method shows promise in aiding clinical decision-making for palliative care in super-aged populations.
