Introduction

The objective of the research study was to compare the effects of integrated data information displays with traditional data displays used by Intensive Care Unit (ICU) nurses. The study measured outcomes to determine if using an integrated information display improved the accuracy of interpretation and reduced task completion times compared to the use of traditional displays.

Method

The researchers used a counter-balanced (display order) repeated measures study, with experienced a ICU nurses randomly divided into two groups. Two separate study sessions were conducted in which each group used traditional displays during one session and integrated displays in the second session. The difference between the two groups was the order in which the traditional or integrated display types were viewed. Tools use to control for individual differences and learning effects included competency testing, repeated measures and randomize presentation. [1]

To create the integrated display, traditional tabular displays from multiple sources were integrated into a single visual interface with information for similar tasks displayed in close proximity. [1] Medication administration information was shown concurrently with trending historical vital signs. Visual cues were added to notify nurses of changes in orders for equipment settings and to facilitate accurate medication administration. Monitored outcomes measured were.

  • Accuracy based on questions regarding perception, understanding and anticipation of future implications
  • Task completion time based on response time to answer questions

Results

Compared to traditional graphical displays, integrated displays resulted in:

  • Increase in accuracy from 61.8% to 85.3%
  • Decrease in median task completion time from 42.1 to 26.0 seconds

The findings may have been influenced not only by integration of displayed information but by the prominent, appealing visualization associated with the integrated display presentation. This study of integrated display is not conducive to generalization because it was designed to address specific deficits found in the ICU setting.

Conclusions

Nurses responded positively to the usability of integrated information displays. Those who used the integrated format demonstrated more accuracy of perception, understanding and Situational Awareness. The decrease in task completion time when using an integrated information display helped to improved productivity and promoted faster response times to developing patient needs. Additional studies could be conducted to discover which levels of situational awareness are most improved by using integrated information displays.
