We have had some medical Category:Labs Imaging count entries that are so high that they are likely errors.
What are likely maximum entries?
The count per patient stay is related to the LOS. The threshold limits are either Mean + 3 Standard Deviation or Maximum value of Chest X-ray count per patient day for various LOS category listed in the table below. They are derived from July 1988 to June 2017 Lab data. The LOS is based on calendar dates where partial stay is considered as full day.
- LOS based on calendar dates = Dispo DtTm - Arrive DtTm + 1
|
would we not use Accept DtTm here? Because we could have CXRs on days before arrival... |
- if patient is still in the unit, Dispo DtTm is replaced by today's date
- Chest X-ray (CXR) per patient day = Number of chest X-rays / LOS Based on calendar dates
| LOS_days | N | Mean | Std Dev | Minimum | Median | 75th Pctl | 90th Pctl | 95th Pctl | 99th Pctl | Maximum | mean + 3 Std Dev | Limits of CXR per patient day |
