Mortality risk stratification can predict readmissions but not length of stay

To determine whether the mortality risk stratification (MORIS) strata can predict outcomes including mortality, readmission, and discharge disposition for specific diagnoses.

Retrospective, observational study for hospitalized patients in 2016-2017 at an urban, medium-sized, community tertiary care hospital. All admitted patients with 1 of the following diagnoses were included in this study: acute myocardial infarction, chronic obstructive pulmonary disease, congestive heart failure, pneumonia, and sepsis.

No interventions were applied in this retrospective study. Data collected from patients admitted under 1 of the 5 diagnoses included mortality, length of stay (LOS), readmission, and discharge disposition.

MORIS strata can predict condition-specific mortality and readmissions but not length of stay or discharge disposition.

Stewardship of resources is necessary to obtain high value in care. A long LOS, discharge to skilled nursing facilities, and unplanned readmissions contribute to a significant utilization of resources. The MORIS strata are useful in predicting disease-specific mortality and readmission, but they are not useful in predicting LOS or discharge disposition.
