Abstract

Introduction: Clinical information systems (CISs) used in intensive care units (ICU) integrate large amounts of patient data every minute, and from multiple systems and devices. Intensive care requires efficient use of information technology to acquire, synchronize, integrate, and analyze data in order to make quick decisions and implement interventions in a timely manner.

Objectives: To identify factors affecting poor user experience (UX) of CISs used in ICUs in Finland.

Methods: Data from national Electronic Health Record (EHR) and user experience survey was undertaken in 2017. Those, who used the ICU CIS on a daily or weekly basis were asked supplementary questions and, therefore, comprise a subset of the responses reported in this article.

Results: On a 4–10 scale (i.e., “Fail” to “Excellent”), the mean ‘grade’ for the principally used ICU CIS was 6.9 (SD 1.3) points. Of the respondents, 119 (57%) were categorized as having good UX. The factors identified as affecting poor UX of the ICU CISs related to poor interface design (OR 7.8; 95% CIs 12.5–24.1; p = 0.001), insufficient customizability (OR 7.2; 95% CIs 1.7–30.6; p = 0.008), the inefficiency of performing routine tasks (OR 4.3; 95% CIs 1.0–18.2; p = 0.044), malfunctions (OR 3.5; 95% CIs 1.2–9.6; p = 0.019), and difficulties in information retrieval (OR 3.0; 95% CIs 1.0–8.8; p = 0.044). The most commonly reported usability problems with the main EHR system and ICU CISs were also identified.

Conclusions: Overall satisfaction with the principally used ICU CIS was moderate. However, the overall grades varied significantly. Poor interface design, insufficient customizability, inefficiency, malfunctions, and difficulties in information retrieval all affect poor UX.
