Comparison of algorithm-based cage changes and traditional cage change frequency with resulting operational efficiency savings over a 10-mo period at our facility
| Cage density | No. of cages | Traditional 2-wk cage change over 10 mo | Cage change based on algorithm recommendations over 10 mo | Percent decrease |
|---|---|---|---|---|
| 1 | 150 | 3,000 | 903‡ | 70 |
| 2 | 38 | 768 | 279‡ | 64 |
| 3 | 34 | 687 | 333‡ | 52 |
| 4 | 4 | 81 | 15‡ | 81 |
| 5 | 25 | 505 | 259‡ | 49 |
| Total | 251 | 5,041 | 1,789‡ | 65 |
A one-sample Wilcoxon test was used to compare the 14 d change out compared with BSI alert-based cage change. A one-sample t test was used for 4 animals per cage comparison. ‡, P < 0.001.
