Group C (Score 11.1-17.5): Poor Prognosis

Frequently Asked Questions
What is the PaP score used for?
The Palliative Prognostic (PaP) Score is a validated tool used to predict 30-day survival probability in patients with advanced cancer receiving palliative care. It helps clinicians make informed decisions about treatment goals, hospice referrals, and advance care planning discussions.
How accurate is the PaP score?
The PaP score has been validated in multiple studies with good accuracy. Group A patients have greater than 70% probability of 30-day survival, while Group C patients have less than 30% probability. However, it should be used as a guide alongside clinical judgment, not as the sole determinant of prognosis.
How do I determine the clinical prediction of survival?
Clinical prediction is the physician's estimate of how long the patient will survive based on experience and clinical judgment. Studies show that clinicians tend to be overly optimistic by a factor of 3-5. It's best to make this estimate objectively based on disease trajectory, performance status, and recent changes in condition.
What is the Karnofsky Performance Status?
The Karnofsky Performance Status (KPS) is a scale from 0 to 100 that measures a patient's functional status and ability to perform activities of daily living. For the PaP score, only scores of 10-20 (severely disabled, requiring hospitalization) receive points. Higher KPS scores indicate better functional status.
Can the PaP score be used for non-cancer patients?
The PaP score was developed and validated specifically for patients with advanced cancer. It has not been validated for non-cancer terminal illnesses such as heart failure, COPD, or dementia. Other prognostic tools may be more appropriate for these populations.
How often should I recalculate the PaP score?
Reassess the PaP score whenever there is a significant change in the patient's clinical condition, such as new symptoms, declining performance status, or changes in laboratory values. For stable patients, weekly or biweekly reassessment is reasonable in the palliative care setting.
Should I share the PaP score with patients and families?
Prognostic information should be shared sensitively and in accordance with the patient's wishes. Some patients want detailed numerical predictions, while others prefer general timeframes. Use the PaP score to guide discussions but focus on quality of life, goals of care, and what the prognosis means for treatment decisions rather than raw numbers.
What are the limitations of the PaP score?
The PaP score has limitations including: variability in clinical prediction accuracy, inability to account for all individual patient factors, development in cancer patients only, and prediction of groups rather than individuals. It should complement, not replace, comprehensive clinical assessment and judgment.

Understanding the Palliative Prognostic Score
The Palliative Prognostic (PaP) Score is a validated clinical tool designed to predict short-term survival in patients with advanced cancer receiving palliative care. Developed in the late 1990s, it combines clinical assessment, functional status, symptoms, and laboratory values to estimate the probability of 30-day survival. This information helps guide critical decisions about treatment goals, hospice referrals, and advance care planning.
Components of the PaP Score
The PaP score incorporates six key components: dyspnea (shortness of breath), anorexia (loss of appetite), Karnofsky Performance Status, clinical prediction of survival, white blood cell count, and lymphocyte percentage. Each component contributes points to the total score, which ranges from 0 to 17.5. The combination of subjective clinical assessment with objective laboratory data provides a more comprehensive prognostic estimate than either approach alone.
The Role of Clinical Prediction
Clinical prediction of survival by the treating physician is one of the most heavily weighted components of the PaP score. Research has shown that clinicians can reasonably estimate prognosis, though they tend to be overly optimistic by a factor of 3 to 5. The PaP score helps calibrate clinical intuition with objective data. When making a clinical prediction, consider the disease trajectory, recent changes in condition, response to treatments, and overall trajectory of decline.
Understanding Risk Groups
The total PaP score classifies patients into three risk groups. Group A (score 0-5.5) indicates good prognosis with greater than 70% probability of 30-day survival and median survival exceeding 60 days. Group B (score 5.6-11) represents intermediate prognosis with 30-70% probability of 30-day survival and median survival of 30-60 days. Group C (score 11.1-17.5) indicates poor prognosis with less than 30% probability of 30-day survival and median survival less than 30 days.
Clinical Applications in Palliative Care
The PaP score serves multiple purposes in palliative care. It helps identify patients who may benefit from hospice referral, particularly those in Group C who are likely to die within weeks. It guides conversations about goals of care and helps patients and families understand what to expect. It can inform decisions about whether to continue disease-directed therapy or transition fully to comfort-focused care. The score also helps palliative care teams allocate resources and plan care intensity.
Communicating Prognosis Sensitively
While the PaP score provides valuable prognostic information, communicating this information requires sensitivity and skill. Always assess the patient's desire to know prognostic information before sharing specific numbers or timeframes. Some patients want detailed statistical predictions, while others prefer general descriptions like "weeks to months" or "limited time." Focus discussions on what the prognosis means for treatment options, goals of care, and quality of life rather than on the numbers themselves.
Limitations and Considerations
The PaP score has important limitations. It was developed specifically for cancer patients and has not been validated in non-cancer terminal illnesses. It predicts survival for groups of patients, not individuals, and individual patients may survive much longer or shorter than predicted. The score cannot account for all factors affecting prognosis, such as acute complications, treatment responses, or psychosocial variables. It should be used as a guide to inform clinical decision-making, not as a definitive predictor or the sole basis for major decisions.
Integration with Comprehensive Care
The PaP score is most valuable when integrated into comprehensive palliative care assessment. Use it alongside assessment of symptom burden, functional status, psychosocial needs, and spiritual concerns. Reassess regularly as clinical conditions change. Combine prognostic information with excellent symptom management, psychosocial support, advance care planning, and caregiver support. The goal is not just to predict survival, but to optimize quality of life for whatever time remains.
