The primary objective of this paper is to explore whether COVID-19 affects nurses’ behavior on updating assessment results in EMRs in an intensive care unit (ICU) and analyze how the patterns of updating assessment results can be different. The study considered information from March (before the pandemic) and July (during the pandemic) in terms of average process time and frequency. In this study, the response-time measurement system data was used to analyze ICU nurses’ workflow related to EMR documentation. After that, multiple hierarchical task analysis (HTA) charts were developed to find different EMR documentation patterns for assessment results. The results revealed that these patterns were significantly different in terms of average process time and frequency before and during the pandemic. The finding of this study might reveal the possible impact of COVID-19 pandemic on the patterns of updating patient assessment results and how nurses’ preferences can be different in terms of average process time and frequency.
