“…However, there has been little systematic scientific study to quantify the global nature of the home health care device usability problem and characterize device usability in a field situation. Much of the available literature has tended to focus around a handful of devices, such as pregnancy test kits [ 9 ], cholesterol test kits [ 10 ], glucometers, and other diabetes management tools [ 11 ]. Studies typically assess a few medical devices of a single type in a laboratory setting, making it difficult to compare usability across studies and devices.…”

BackgroundAn increasing amount of health care is now performed in a home setting, away from the hospital. While there is growing anecdotal evidence about the difficulty patients and caregivers have using increasingly complex health care devices in the home, there has been little systematic scientific study to quantify the global nature of home health care device usability in the field. Research has tended to focus on a handful of devices, making it difficult to gain a broad view of the usability of home-care devices in general.ObjectiveThe objective of this paper is to describe a remote usability assessment method using the System Usability Scale (SUS), and to report on the usability of a broad range of health care devices using this metric.MethodsA total of 271 participants selected and rated up to 10 home health care devices of their choice using the SUS, which scores usability from 0 (unusable) to 100 (highly usable). Participants rated a total of 455 devices in their own home without an experimenter present.ResultsUsability scores ranged from 98 (oxygen masks) to 59 (home hormone test kits). An analysis conducted on devices that had at least 10 ratings showed that the effect of device on SUS scores was significant (P<.001), and that the usability of these devices was on the low end when compared with other commonly used items in the home, such as microwave ovens and telephones.ConclusionsA large database of usability scores for home health care devices collected using this remote methodology would be beneficial for physicians, patients, and their caregivers.

“…According to the principles of human-centric design, a key step in improving user experience in any context is to identify and address the functional constraints associated with a task through consultation with end users. 11 Previous studies have successfully employed this strategy to inform improvements to collection processes for HIV selftest kits 12 , instructions for test kits targeting cholesterol 13 , and home bowel cancer screening. 14…”

Objectives: Despite the widely publicised health benefits of participation in bowel cancer screening, only 43.5% of recipients participate in the Australian National Bowel Cancer Screening Program (NBCSP). Through consultation with kit recipients, this study aimed to identify features of home bowel screening kits that could be modified to increase their use.Method: Participants (n = 25) were presented with nine different bowel cancer screening kits and asked to identify features of each kit that might prevent or promote their use. Responses were coded using content analysis, and a narrative synthesis is presented summarising preferences relating to each element of the kit.Results: Six modifiable elements were identified: collection tool, collection sheet, specimen container, instruction, packaging and processes. Participant preferences were for collection devices that limited the users' proximity to faecal matter, smaller packaging, simpler processes and step-by-step pictorial instructions. Responses regarding aesthetics, the amount of information included and receiving immediate results were mixed. Conclusions:Findings provide several consumer-driven recommendations, which are to be tested in future research aimed at improving the acceptability and usability of kits distributed in population bowel cancer screening programs.

“…21 This approach, however, brought in other inaccuracies stemming from the signal-generating system that requires a significant amount of blood to be sucked into the test strip, as well as an operational inconvenience due to several minutes of waiting time between successive steps. 35 These challenges may be overcome to some extent by using complementary metal oxide semiconductor (CMOS)-based detection, 36 including multi-modal analytical features such as integrated colorimetric, chemiluminescence, surface plasmon resonance and hydrogen ion measurements. 37…”
