Summary

Hospital way-finding is challenging for those with low vision. Decorative elements, lighting issues, and poor signage create significant obstacles, increasing fall risks for aging patients.

Area of Science:

  • Healthcare accessibility
  • Human factors engineering
  • Gerontology

Background:

  • Aging populations experience declining vision and increased health issues, complicating navigation in healthcare settings.
  • Effective way-finding is crucial for patient safety and reducing stress within hospitals.

Purpose of the Study:

  • To investigate way-finding challenges faced by individuals with simulated low-vision impairments in a hospital environment.
  • To identify specific environmental factors that hinder navigation for patients with visual impairments.

Main Methods:

  • A pilot study involving 50 healthy, sighted participants using five low-vision impairment simulators.
  • Participants navigated common hospital paths, with data collected through objective observation and subjective questionnaires.
  • Analysis focused on obstacles encountered during way-finding tasks.

Main Results:

  • Decorative elements significantly disrupt way-finding for individuals with low vision.
  • Inconsistent lighting alters perceptions of space, making corridors appear crooked and doorways misleading.
  • Signage issues, including text size, placement, illumination, and physical size, were frequently unsatisfactory.

Conclusions:

  • Low-vision simulation effectively identifies environmental barriers in hospitals.
  • Addressing decorative elements, lighting, and signage can mitigate way-finding difficulties and reduce fall risks.
  • Hospitals can enhance patient safety and reduce frustration by implementing evidence-based environmental modifications.
