Relationship between Pediatric ICU Length of Stay and 24-Hour-Unplanned Readmission Rate.

OBJECTIVE
To evaluate the relationship between Pediatric Intensive Care Unit (PICU) Severity-Adjusted Length of Stay (LOS) and 24-hour-unplanned readmission rate.


DATA SOURCE
10-year cohort from 2009-2018 from the Virtual Pediatric Systems (VPS, LLC) database.


STUDY DESIGN
In this retrospective study, Standardized Length of Stay Ratio was computed for each Pediatric Intensive Care Unit as the ratio of the sum of actual Length of Stay divided by the predicted Length Of Stay for each Pediatric Intensive Care Unit using VPS predictive length of stay model. Correlation between Standardized Length of Stay Ratios and 24-hour-unplanned readmission rates were computed using Pearson's correlation coefficient.


PRINCIPAL FINDINGS
There was practically no relationship between Standardized Length of Stay Ratio and 24-hour readmission rate (R2 = 0.05).


DATA COLLECTION/EXTRACTION METHODS
Not Applicable CONCLUSIONS: Severity-Adjusted Length of Stay has no relationship with 24-hour- unplanned readmission rate. These findings suggest that the relationship between PICU severity adjusted LOS and 24-hour- unplanned readmission rate should not be used as a balancing quality measure.
