Relationship between complexity of the prescribing decision and decision outcomes
| Relative complexity of the decision
|
||||
|---|---|---|---|---|
| Lower | Higher | Statistical difference between groups | ||
| Mean complexity scores | ||||
| MML, bits | 35.8 | 67.7 | t=34.75 | p<0.001 |
| CASA | 17 | 33 | t=14.59 | p<0.001 |
| EIP | 164 | 388 | t=22.74 | p<0.001 |
| Agreement with the expert panel, n (%) | 99/124 (80%) | 79/124 (64%) | Chi S = 7.96 | p= 0.005 |
| Confident or highly confident of prescribing decision, n (%) | 97/124 (78%) | 79/124 (64%) | Chi S = 6.34 | p=0.012 |
| Time taken (seconds per case) | ||||
| Mean | 125 | 156 | t = 2.58 | p=0.010 |
| Median | 91 | 120 | ||
| SD | 95 | 94 | ||
Chi S = Chi square; MML, minimum message length; CASA, clinical algorithm structure analysis; EIP, elementary information process.
