  • *The proportion correctly reclassified is in those who have readmission using the probabilities from the model based on each score and the model based on each score adjusted by LTCI, the proportion of individuals reclassified to a higher risk minus the proportion reclassified to a lower risk; in those who do not have readmission, the proportion of individuals reclassified to a lower risk minus the proportion reclassified to a higher risk.

  • †The net reclassification improvement is the sum of correctly reclassified individuals with and without readmission.

  • ‡p<0.10, §p<0.05.

  • IDI, integrated diagnostic improvement; LTCI, long-term care insurance; NRI, net reclassification improvement.
