Human Factors Engineering

Human Factors Engineering describes the discipline of designing medical products, devices, and interfaces to minimise user errors and improve safety by accounting for human capabilities, limitations, and real-world usage conditions. In biopharma, this is especially relevant for self-administered therapies using autoinjectors, prefilled syringes, inhalers, and wearable delivery systems.

The pharmaceutical industry integrates human factors engineering into combination product development to support safe and effective use across diverse patient populations. Studies assess usability risks such as incorrect injection technique, dose misreading, device handling challenges, or packaging confusion. Regulatory agencies require evidence that device designs mitigate foreseeable errors through appropriate labelling, training materials, and design controls. Human factors findings influence product design decisions including grip shape, force requirements, audible feedback, and step simplification. As patient-centric care expands and home administration becomes more common, human factors engineering increasingly determines real-world success of therapies.
