Causes failure modes​

  • Users enter non-existent or anatomically incorrect body sites.
  • Users input the wrong body site due to typos or misunderstandings.
  • Users specify body sites in an ambiguous manner, leading to confusion (e.g., "arm" instead of "left forearm").
  • Lack of documentation, guidance or prompts to help users accurately specify the body site.
  • Errors in mapping user-specified body sites to the system’s internal representation.
  • The system does not or incorrectly validate user input for body sites, allowing invalid entries to pass through.

Related risks​

    1. The endpoints of the device are not compatible with the user's software
    1. Medical device input requirements are not defined to users to its proper operation
    1. Inadequate specification of the product intended purpose.

User Requirement, Software Requirement Specification and Design requirement​

  • User Requirement 11.1: Users must be able to specify the body site of the skin structure in the request.
  • Software Requirement Specification 11.2: The device must accept and process input regarding the body site of the skin structure in relation to the submitted image.
  • Design Requirement 11.3: Ensure device request formatting allows for clear and standardised submission of body site data in line with healthcare data standards.

Description​

Just as age and sex hold significance in clinical diagnoses and medical assessments within the field of dermatology, the location on the body, referred to as "body sites," is equally vital. Dermatological conditions often manifest with varying visual characteristics depending on the specific body site, and their prevalence can differ accordingly. For instance, acne predominantly appears on the face in most cases.

Within this requirement, our focus lies in providing users with the means to specify the precise body site related to a skin structure. This task extends beyond merely introducing a data field; it entails the creation of a taxonomy that is both user-friendly and practical for the device. The taxonomy categorizes body sites hierarchically, commencing with the broad category of the whole body and progressively branching into more specific locations like the head, face, mouth, and lips. The finalized taxonomy will be available in our documentation, ensuring clarity and ease of use.
