Administering an IV Pump Bolus: Performance Metrics by Experimental Condition
| Performance Metric | Sample Size, n | Opportunities for Performance Metric Per Experimental Condition | Experimental Condition | Statistics | ||
|---|---|---|---|---|---|---|
| Baseline (Traditional Pump) | Traditional Pump With Bolus Feature | Smart Pump With Bolus Feature | ||||
| Programming errors, n (%) | 39a | 78 (2 per participant) | 9(11.5%) | 8(10.3%) | 1 (1.3%) | F(2, 76) = 3.167 P = 0.048 |
| Task time, s | 38a | 38(1 per participant) | 30 | 37 | 38 | F (2, 74) = 0.849 P = 0.43 |
Abbreviation: IV, intravenous.

One participant (of 40) refused to give an IV pump bolus in the baseline condition because of concerns about bolusing other infusions running into the same access port (i.e., dead volume, see Theme 3: Managing Dead Volume); this participant's data were excluded from the comparative analysis of programming errors and task time, reducing the sample size from 40 to 39. Because of issues during data collection, another participant's data were excluded from the comparison of task time, reducing the sample size to 38.
