The Overstay2 colour is a colour assigned to a patient based on data collected as part of Project Overstay2, which is run through the Overstay2 scoring models to generate a score and the Overstay2 colour. The colour modifies the Overstay2 processes on the units to reduce discharge delay. See Overstay2 Overview for more context.
The colour is based on a probability threshold that is set to balance the number of patients followed under the more elaborate Overstay2 processes on the units to reduce discharge delay#red process wile minimizing the number of patients who would overstay by more than 10 days that are not captured. It was set separately for each of the Overstay2 scoring models, so see those pages for the actual thresholds.
Method of setting threshold
Optimal threshold
|
|
This would have resulted in a assigning xxx% of patients a "red". This would have overwhelmed the Overstay2 processes on the units to reduce discharge delay so we needed to determine a #pragmatic threshold.
Pragmatic threshold
We used the following process to set a red/yellow threshold that our Overstay2 processes on the units to reduce discharge delay can function with.
Goals/considerations
The thresholds were set to stratify patients based on the following considerations:
- goal: reduce LOS 10-15%
- no more than 15-17% of patients tagged
- capture 60-75% of all delayed discharges

How did those get set, though? If they are arbitrary then any rigor in balancing them is just dazzle. Ttenbergen 19:48, 8 June 2025 (CDT) |
