Unifying HF Usability: Streamlining Processes Inside Departments

Industry

Healthcare

Method

Consulting, IDIs, Co-creation workshop

Duration

1.5 Years

Background

A large medical systems manufacturer with 5 different departments, all following different usability processes, wanted to streamline its usability processes. Historically, the different departments had been developing their usability processes in silos.  Our task was to help our client build one usability process for all departments, based on the feedback and needs of each department.

Approach

  • We interviewed different types of stakeholders (UX/usability engineers, risk managers, developers, managers, etc.) to map out each departments' usability processes.

  • Afterwards, we facilitated several rounds of iteration workshops with stakeholders to refine early designs of a unified process for all departments and select the best approach.

Outcome

A final common usability process could be established, taking into account the requirements of all departments' stakeholders and the guidelines and regulations (FDA/IEC)

The common usability process was tested successfully during a pilot roject and the client decided to move forward and implement it across all departments.

Validating a Digital Biomarker App for Clinical Trials

Industry

Healthcare

Method

Formative usability test, Health app testing

Duration

3 months

Background

A pharmaceutical manufacturer was planning to use a smartphone app in a clinical trial. The app consisted of several tests to assess specific disease symptoms.

The data captured via the app would help assess changes of patients’ abilities and therefore potentially assess the effectiveness of the treatment.

To ensure usability of the app and if it would capture appropriate data , it had to be tested with patients prior to launch.

Approach

  • We recruited 20 patients diagnosed with different stages of a neurodegenerative disease.

  • During face-to-face interviews, patients were asked to use the smartphone app and its “games”.

  • For some sessions, alternative versions (e.g., with several difficulty levels, or different parameters) were tested to identify the best design and/or baseline settings.

Outcome

The research revealed several usability issues with the app. Additionally, we showed that some of the instructions were not understood by all participants and could be a source of confusion.

Based on these results, uintent provided recommendations for the manufacturer to address before the app’s launch in the clinical trial.

Method

Summative usability test

Duration

4 months

Background

A medical device manufacturer was devel-oping a new angiography system, which included a hard- and software update of the previous version.

The study intended to demonstrate that critical use tasks could be performed safely and effectively by the intended users in the intended use environment.

Approach

  • A summative evaluation was carried out with n=15 intended users in a market research facility, on a partial angiography system.

  • Use tasks were assessed via simulated use, and warnings in the instruction manual were assessed via a comprehension assessment.

Outcome

Results for the simulated use tasks were categorized and a detailed root causes analysis was performed for non-successful tasks. A residual risk analysis was conducted.

Comprehension of the warnings was also assessed, results were categorized, and a root cause analysis was performed. The final HFE report was used for FDA submission.

Evaluating Safety & Usability: Validation of a Patient Supply Unit Interface for HCPs

Industry

Healthcare

Method

Summative usability test

Duration

2 months

Background

A medical device company required a validation study to determine if the use of a patient supply unit was safe and effective.

Our task was to determine if nurses and physicians can operate the height adjustment and mobility features of the unit, considering the interface modifications from the previous model. We also examined the capability of service technicians to execute specific maintenance tasks associated with the device.

Approach

N=20 face-to-face usability test sessions were conducted with the intended user groups - nurses, physicians and hospital technicians.

The interviews took place directly at the client’s premises due to the technical setup restrictions of the supply units.

Outcome

Participants successfully executed usage and maintenance tasks for the patient supply units.

Nonetheless, the study revealed new technical issues with the supply unit.

Subsequently, the manufacturer utilized the study findings to proactively address and resolve these identified issues.
