Abstract
Background: Survival prediction for advanced cancer patients impact many aspects of care. Multiple prognostic tools have thus been developed to provide clinicians with more accurate information on the prognosis of advanced cancer patient. Palliative Prognostic index (PPI) is a simple tool and can accurately predict the survival of these patients. There’re no studies in Thailand that use PPI for predicting the survival of advanced cancer patients with palliative care at home.
Objective: To evaluate the prediction accuracy of the Palliative Prognostic index in patients with advanced cancer in palliative Home care
Methods: The prospective cohort study in advanced cancer patients and come to the hospital as the outpatient service. Every patient was interviewed with PPI tool, and then was followed until the end of the study. We find the accuracy of predicting the survival time which is less than 3- and 6-week using ROC curve analysis. The survival curves and the 95% confidence intervals of survival were calculated by the Kaplan-Meier method, and comparisons were based on the Log-rank test.
Results: From 140 patients, mean age was 61.5 years. The Median survival time was 63 days (95%CI: 22-163). For 3- and 6-week survival, prognostic prediction showed respective overall accuracy of 0.83 (95%CI 0.76, 0.91) and 0.85 (95%CI 0.79, 0.91).
Conclusion: The survival of advanced cancer patient in Palliative Home care can be acceptably predicted by Palliative prognostic index
