Predicting survival in cancer patients with and without 30-day readmission of an unplanned hospitalization using a deficit accumulation approach
Cancer Medicine Sep 14, 2019
Hembree TN, et al. - Given that estimating survival has been limited for cancer patients with an unplanned hospitalization, researchers assessed predictors of survival and examined the concept of using a deficit-accumulation survival index (DASI) in this population. From 145 patients who had an unplanned 30-day readmission between 01/01/16 and 09/30/16, medical records were obtained to extract data. They gathered comparison data for patients who were admitted as close in time to the date of index admission of a study patient but were without a readmission within 30 days of their discharge date. Those readmitted within 30 days were compared with those who were not in terms of survival. They found a strong link between 30-day readmission and survival. The utility of DASI for survival prediction was evident; median survival time was 78 days and 318 days for the high score and for the moderate score, respectively, and not reached as of 426 days for the low-score DASI group. A higher risk of mortality was observed among those readmitted within 30 days of an unplanned hospitalization vs those not readmitted.
