Functional Barriers to Access for Virtual Care

Potential Barriers to Access for Virtual Care

This document draws on earlier research conducted by the Inclusive Design Research Centre to understand barriers to access for information and communication technologies more generally. The document outlines barriers in terms of functional requirements and personal constraints that need to be considered to provide flexible way to access services or operate devices and systems that may be part of virtual healthcare.

When understanding barriers to access, it is helpful utilize the social model of disability which defines disability as a product of the environment, design or even society. In this way, a barrier or a disability can be viewed as a mismatch between the access needs of the individual (based upon their skills and constraints) and the access options provided by the service. Systems that are flexible and responsive to individual needs and preferences are most likely to be accessible and able to meet the needs of diverse populations, even needs not yet articulated. Therefore it is helpful to treat mismatches as affecting individuals rather than homogeneous "vulnerable populations".

Approach

The following sources of information and techniques were used to gather the information about barriers:

  • Literature review
  • Review of litigation
  • Press review
  • Ombudsman reports
  • Disability advocacy organizations
  • Research, reviews and summative reports
  • Interviews with key organizations of people with disabilities
  • Interviews with disability studies organizations
  • Interviews with organizations for people with disabilities

Potential Barriers by Functional Requirements

The following operational requirements may present barriers.

Device Manipulation Barriers

Fine Motor Control

  • writing (e.g. form-filling, signatures, stylus, “mouse signatures” etc.)
  • physical manipulatives (e.g. swipe cards, etc.)
  • devices with small controls (e.g. keypads, keyboards)
  • devices requiring accurate pointing or gestures (e.g. mouse, touch screens, flat membrane keyboards)
  • devices employing tactile feedback

Gross Motor Control

  • devices that are easily damaged
  • devices that are sharp or otherwise dangerous
  • requirement to communicate in-person (as opposed to by phone or online)
  • web sites or software lacking keyboard accessibility
  • time constraints on use of communication

Effort & Reach

  • excessive force
  • reach (e.g. touchscreens)
  • sustained effort (e.g. stylus)
  • use of both arms simultaneously
  • operating two parts simultaneously
  • tight grasping
  • pinching
  • twisting of the wrist
  • quick repetition (e.g. mouse clicks)
  • device controls out of sight/reach from sitting position (e.g. kiosk)

Communication Barriers

Speech

  • as primary communication mode (e.g. language, spoken, gestural)
  • voice recognition (e.g. software, phone systems)
  • voice identification
  • barriers to lip reading (e.g. camera position, speaking quickly, masks)

Modality

Information conveyed through visual means:

  • print documents and other text (e.g. forms, publications, books)
  • graphics (e.g. images showing placement of blood pressure cuff)
  • videos
  • visual feedback/indicators/alarms
  • dynamic communication devices (e.g. touch screens, soft controls such as buttons depend on mode)
  • web sites or software (lacking keyboard accessibility, semantic markup for visual layout or other supports)
  • colour-coding or colour indicators

Information conveyed through sounds:

  • auditory feedback
  • indicators/alarms
  • lack of volume control

Cognitive Load

  • complex or unnecessary information
  • lack of attention cues
  • lengthy phone menus
  • expectation of continuous concentration (e.g. more than 15 mins)
  • lack of memory cues and supports (e.g. instructions)
  • expectation to retain and recall information

Processing

  • complex or inconsistent text (e.g. forms, signs, etc.)
  • text-intensive information displays
  • time constraints on use or communication
  • complex or unnecessary use of numbers or math
  • time-telling, calendar use
  • lack of word prediction or spell-checking support

Other Barriers

Physical Barriers

  • biometric identification
  • devices sensing body parts (e.g. capacitive or infrared controls)
  • devices designed for a specific hand
  • iris or other eye identification

Equipment Barriers

  • not operable with AT
  • older equipment (e.g. due to constraints on technology refresh funding) may not meet system requirements

Attitudinal Barriers

  • when no other barrier exists, an individual who is older, has a disability or is in some other way perceived as vulnerable, may still be prevented from performing an action by a person in authority with an inappropriate attitude

Privacy & Security

  • privacy threats (e.g. remote setting limits privacy, audio output overheard)
  • information and data security (e.g. network security)

Scenarios

The following are scenarios where patients are required to perform certain functions in order to engage in virtual healthcare appointment booking and attending.

  • Using a software platform to register and book an appointment
  • Prepare for an appointment
  • Attending the virtual visit and dealing with any technical issues
  • Any asynchronous interactions such as chat or sharing of documents

Another application of virtual healthcare is the use of remote patient monitoring. The following are example scenarios where patients are required to perform a functions in order to engage in this aspect of virtual healthcare:

  • Enrolling in the program
  • Setting up the equipment and service
  • Scheduling coaching or training
  • Submitting records or data
  • Completing health surveys
  • Dealing with alerts, and clinician interventions

In all these scenarios, whether it is booking an appointment or setting up a health monitoring device, a number of functional barriers can arise that will affect an individual's ability to complete the activity. For example, if the instructions for setting up a device uses small text that isn't legible to the user, the user will experience a barrier in participating in this aspect of healthcare.
