Abstract

Healthcare organizations must evolve and adopt current evidence-based practices while maintaining care quality and operational effectiveness. Human-computer interaction is essential to enhancing clinical trial management processes and ensuring patient safety by optimizing how healthcare providers engage with critical information systems. However, technology transitions present challenges that require effective training and evaluation to ensure smooth adoption and usability. To strengthen clinical research capabilities, a comprehensive workflow and process mapping strategies was implemented to develop a novel custom-built electronic medical record application, PowerTrials. Understanding how healthcare team members interact with the PowerTrials interface during training is crucial for identifying potential shortcomings and optimizing future training designs. This study aimed to improve PowerTrials training by analyzing staff perceptions, performance, and user experience through biometric data. Two pre-recorded videos on clinical trial information and PowerTrials interface navigation were presented to 17 and 27 clinical participants, respectively, from a rural hospital in the western United States. Eye-tracking and facial expressions, along with quiz scores were collected to evaluate the PowerTrials training sessions. On average, participants directed more visual attention to key text (2,707 fixations) compared to random images (390 fixations) and focused more on central screen content (1,995 fixations) than on side content (512 fixations). Negative emotions were noted more frequently (38.6%) than positive ones (0.4%) based on emotional intensity. Pop-up windows and audible explanations effectively captured participant attention. Quiz results showed higher scores for the PowerTrials interface training (91.3/100) than for the clinical trial information training (85/100). Future research will evaluate user interaction with PowerTrials following training to further refine the interface.

1. Introduction

Healthcare organizations, like other large private and public organizations, must continue to evolve and change to keep current with evidence-based practices but also to maintain care quality, operational effectiveness, and efficiency [1]. Private industry has a long-standing history of proactively addressing organizational readiness to change [2], organizational resilience and change management. Yet these core dimensions can be implemented in healthcare organizations that enable the use of best practices and lessons learned for a broader impact. Specifically, hospitals can proactively detect those items that are likely to impede successful change using practical managerial tools to implement a transformation, planned or sudden, that enhances organizational...
