Setting Up and Programming Multiple Primary Continuous IV Infusions: Performance Metrics by Experimental Condition
| Performance Metric | Sample Size, n | Opportunities for Performance Metric Per Experimental Condition | Experimental Condition | Statistics | |
|---|---|---|---|---|---|
| Baselinea | One-at-a-Time Protocol | ||||
| Programming errors, n (%) | 20b | 60 (3 per participant) | 7 (11.7%) | 4 (6.7%) | t(19) = 1.14 P = 0.27 |
| Auxiliary labelling errors, n (%) | 6c | 24 (4 per participant) | 0 (0.0%) | 0 (0.0%) | NA |
| Task time, s | 20b | 20 (1 per participant) | 528 | 469 | t(19) = 2.16 P = 0.04 |

Data from participants who used the one-at-a-time protocol in the baseline condition were excluded.
Twenty (of 40) participants were excluded from the comparative analysis of programming errors because they either did not complete the line change task in both the baseline and one-at-a-time conditions due to time constraints (n = 7) and/or they naturally followed a one-at-a-time protocol in the baseline condition (n = 15). Two participants did not complete the task in both conditions and naturally followed a one-at-a-time protocol in the baseline condition. Thus, the number of participants included in the comparative analysis was 20 (i.e., 40 − 7 − 15 + 2).
Only 6 (of 40) participants labelled infusions in the baseline condition; only those 6 were included in the comparative analysis of labelling errors.
