This study had the following specific aims:
This experiment was also conducted in the Human Exploration Research Analog (HERA), during HERA 1 Campaign, missions 2-4 to test the ease and usability of the handheld device in regards medication usage.
Six crewmembers completed flight data collection and five completed ground data collection before NASA’s early study discontinuation. There were 5766 medication use entries, averaging 20.6 ± 8.4 entries per subject per flight week. Types of medications and their indications were similar to previous reports, with sleep disturbances and muscle/joint pain as primary drivers. Two subjects treated prolonged skin problems. Subjects also used the application in unanticipated ways: to note Drug Tolerance Testing or medication holiday per research protocols, and to share data with flight surgeons. Subjects also provided usability feedback on application design and implementation.
The volume of data collected (20.6 ± 8.4 entries per subject per flight week) is much greater than was collected previously (< 12 per person per entire mission), despite user criticisms regarding app usability. It seems likely that improvements in a software-based questionnaire application could result in a robust data collection tool that astronauts find more acceptable, while simultaneously providing researchers and clinicians with useful data.
