Healthcare Systems Usability Scale (HSUS) enhances clinical decision support system safety

A validated usability scale for clinical decision support systems can proactively identify potential issues, thereby reducing the risk of medical adverse events.

BMJ Open · 2023

01

Key Findings

  • 01The HSUS demonstrated good internal consistency (Cronbach's alpha).
  • 02The scale showed evidence of content, face, and construct validity.
  • 03The HSUS is a reliable tool for identifying usability issues in CDSS.
02

Application

Design takeaway

Integrate the HSUS or similar validated usability assessment tools into the design and development lifecycle of clinical decision support systems to ensure user-friendliness and patient safety.

How to apply

When designing or evaluating any clinical decision support system, use the HSUS to systematically measure and improve its usability.

Project actions

  • 01When designing a system for a specific user group, consider how you will measure its usability.
  • 02Look for existing, validated scales that can be adapted for your project's context.
03

Method & Evidence

AimTo develop and validate a reliable and valid tool for assessing the usability of clinical decision support systems (CDSS) within healthcare settings.
MethodMixed-methods approach involving scale development, validation, and statistical analysis.
ProcedureThe researchers developed the Healthcare Systems Usability Scale (HSUS) through an iterative process, including expert review for content validity, exploratory factor analysis for construct validity, and reliability testing using Cronbach's alpha. The scale was then validated in a clinical context.
ContextHealthcare systems, specifically clinical decision support systems (CDSS).

Variables

IVUsability characteristics of the CDSS.
DVScores on the HSUS, identification of usability issues.
CVType of CDSS, clinical setting, participant roles.
04

Strengths & Limitations

Strengths

  • +Rigorous validation process including multiple forms of validity and reliability testing.
  • +Mixed-methods approach provides both quantitative scores and qualitative insights.

Limitations

Developing a fully validated scale requires significant time, resources, and a large participant pool, which may not be feasible for all design projects.

Reliability & validity

The study employed Cronbach's alpha for internal consistency (reliability) and various methods like expert review and factor analysis for content, face, and construct validity.

Think critically

How might the specific workflow of healthcare professionals influence the perceived usability of a CDSS, and how can a general usability scale account for these nuances?

05

Design Principles

"Usability is a critical component of safety in healthcare technology design."

In healthcare, the usability of digital tools directly impacts patient safety and clinical efficiency. Developing and applying robust usability assessment tools like the HSUS is crucial for designers and engineers creating these systems, ensuring they are not only functional but also safe and effective in practice.

06

What This Means for Your Design

This research created a special checklist (the HSUS) to check if medical computer systems are easy to use. If systems are hard to use, doctors might make mistakes that could hurt patients. This checklist helps find those problems before they cause harm.

How to use in your project

  • 1.Reference the HSUS as a benchmark for usability testing in your design project.
  • 2.Discuss how your design addresses potential usability issues identified by such scales.

Quick Cite

Paragraph starter

The development and validation of the Healthcare Systems Usability Scale (HSUS) highlight the critical link between system usability and patient safety in clinical decision support systems. This research provides a robust framework for evaluating the user-friendliness of such technologies, demonstrating that proactive usability assessment can mitigate risks and prevent adverse medical events. Incorporating validated usability metrics into the design process is therefore essential for creating effective and safe healthcare solutions.
