New calculation helps determine length of stay
Inpatient providers and staff will see a new number on the patient’s Epic story board beginning Nov. 14. The geometric mean length of stay, or GMLOS, represents the typical stay for patients diagnosed with heart failure, COPD, cellulitis, pneumonia and other diagnostic related groups as determined by CMS.
Measuring the GMLOS reduces the effect of very high or low values experienced with average length of stay. A DRG 193 (simple pneumonia and pleurisy w/MCC) has a GMLOS number of 4.0. Likewise, a DRG 329 (Maj small and large bowel proc. w/MCC) has a GMLOS of 9.8.
These numbers allow clinicians to benchmark length of stay so they can make informed decisions about the patient’s expected date of discharge. Each DRG has a geometric mean length of stay. The number is created when provider notes are read electronically from CDI, and coding modules and DRGs are assigned. Those DRGs are compared against published average-length-of-stay and DRG data to provide a customized GMLOS for each inpatient health record.
The GMLOS will change twice daily at 6 a.m. and 4 p.m., seven days a week.
Bedside staff should view GMLOS as a benchmark to be considered with estimated date of discharge. Note that the EDD may capture variables about the patient that are not reflected in the GMLOS. Both values should be considered when working with the patient’s family and the care team to plan and track discharge goals.
