Overview
Estimates short-term survival in advanced illness using PPS, oral intake, oedema, dyspnoea at rest and delirium.
Clinical Significance
In the original study, PPI >6 predicted survival under 3 weeks and PPI >4 predicted survival under 6 weeks; use alongside clinical judgement.
When to Use
- Use as structured clinical decision support when the required data are available and reliable.
How It Is Calculated
- The displayed variables are combined using the published equation or weighted point system.
Interpretation
- In the original study, PPI >6 predicted survival under 3 weeks and PPI >4 predicted survival under 6 weeks; use alongside clinical judgement.
Worked Example
Enter verified patient data in the displayed units; MedicalC applies the published equation or point system.
Limitations
- Classification and prognostic tools can be misapplied outside their validated population.
- Missing, estimated or non-contemporaneous data may materially change the result.
Clinical Pearls
- Document the input values, units, date and clinical setting with the result.
- Use serial scores only when the same instrument and measurement method are used consistently.
Common Mistakes
- Using the tool without confirming entry criteria.
- Selecting overlapping findings that should be represented by the highest-scoring item only.
- Treating a classification threshold as a standalone diagnosis.
