  • Results are shown as mean (SD).

  • Section A=admission work-up; section B=in-hospital evaluation and treatment; section C=discharge readiness/discharge planning; section D=post-discharge period.

  • Equal section weight method—totals of items within each section scaled to maximum score of 25 and summed to a maximum of 100.

  • Equal item weight—total of all items scaled to a maximum of 100.

  • PPR, Potentially Preventable Readmission.
