Linus iADL Assessment [SOFTWARE AS A MEDICAL DEVICE]
Instrumental activities of daily living (iADLs) are things you do every day to take care of yourself and your home. They are one way to measure how well you can live on your own.
The level of dependence while performing iADLs is critical to be able to make the distinction between mild cognitive impairment (MCI), and early dementia. This feature is vital for triaging new therapeutics like Lecanemab and tracking disease progression. Linus's scientific foundation supports predicting iADL performance based on DCR (Digital Clock and Recall) performance. A more accurate prediction is achieved by incorporating both DCR and LHQ (Life and Health Questionnaire) into a model.
Since the validated Functional Activities Questionnaire was pretty expensive, the medical team at Linus decided to create their own set of iADL questions, meant to be offered as our iADL outcome measure. Since this assessment is not validated, the team hosted a Linus-sponsored research study where we were able to show the list of questions to specialists and measure the perceived clinical appropriateness of the questions. This effort allowed us to introduce the Linus iADL Assessment to the market, emphasizing trust and adoption. In the future, this assessment will contribute to Linus Clinical Pathways.
Instant Results
Following the design of our initial assessment in 2021, we identified a gap. Medical Assistants (MAs) are a primary user and need instant result access on the testing device. Within one quarter, we successfully implemented this feature for our customers. Now, it has become a standard practice for each assessment to deliver scores promptly on the Admin App, with accompanying access to the PDF through a web view. This streamlined process allows MAs to efficiently triage next steps. Additionally, the PDF is automatically uploaded to the Electronic Health Record (EHR), eliminating the need for Providers to access the Linus Portal.
PERSONAS
Older Adults/Patients (aged 55+): This user would be an older adult (him/her/them), who may live independently in the community or in an assistive facility and may visit clinics for regular or acute check-ups. In the Linus platform Patients will have the ability to take assessments and view patient facing reports.
Practice Managers: The person who manages the operational aspects of a clinic or practice. In the Linus platform they will have a Clinical Administrator role and have the ability to add and deactivate users in the system.
Clinicians (ex: MD, DO, NP, PA, RN, MA): This can be any healthcare provider or other qualified healthcare professional. In the Linus platform they will have the Clinician role which will give them the ability to add patients, administer assessments and view reports and recommendations.
Primary Site Contacts, Manager Role: These are contacts at our clinical sites who may have responsibility across multiple sites and may want to view patients across many clinic locations within a parent organization. In the Linus platform, Managers have the ability to view the web portal for multiple clinic locations, but they cannot administer assessments.
Linus Admin: A Linus Health employee in the Customer Support department who configures the software for customers and access the system data to help troubleshoot and guide customers through their use of the system.
Researcher: An academic, pharmaceutical or clinical researcher interested in capturing and analyzing tremor or cognitive assessment data.
Personas
We crafted Fictional Characters based on our UXR research, representing diverse user types who may engage with our product or service features. Developing personas is instrumental in comprehending our users' needs, experiences, behaviors, and goals. It enables us to step into the users' shoes, acknowledging their varied needs and expectations. Personas simplify the design process, guide our ideation, and contribute to creating a positive user experience for the target user group.
