Table 1.
Timing | Action | Outcomes |
---|---|---|
Day 0 | Initial monitor screening check | Proportion of inhalers that passed/failed initial screen for 10-week period
|
On two occasions each week | Low use actuations† | Accuracy* in detection of 20 episodes of low use per monitor (1600 actuations in total) |
On three occasions during study period | High use actuations‡ | Accuracy* in detection of three episodes of high use per monitor (960 actuations in total) |
Day 21 | Within study monitor screening check§ | Proportion of inhalers that passed/failed within study monitor check for 10-week period
|
Day 70 | Final data upload and battery test |
|
*Accuracy is determined by actuations correctly detected by the monitor and a lack of spurious actuations.
†Two sets of two actuations performed in the same day.
‡Two sets of eight actuations performed in the same day.
§Performed after actuations for that day (if any), and in half of the monitors only (monitors 1–10).
