Frequently asked questions

What is the PPI?

The Palliative Prognostic Index (PPI) is a clinical-only prognostic tool for advanced cancer patients, requiring no laboratory data — useful at the bedside or in hospice settings.

PPI vs PaP?

PPI is purely clinical (no labs); PaP includes WBC and lymphocyte counts. Both are validated in palliative cancer populations.

What do the thresholds mean?

PPI > 6: predicts survival < 3 weeks (positive predictive value ~ 80%). PPI > 4: predicts survival < 6 weeks. PPI ≤ 4: survival > 6 weeks more likely.

When should PPI be reassessed?

Daily to weekly in inpatient palliative care, or after any significant clinical change.
