Abstract
Adverse effects of EMR use have been rarely reported in South Korea. This study examined nurses' experiences with unintended adverse consequences associated with EMR implementation. The participants were 155 nurses using the EMR for patient care in three public hospitals. The statistically tested 21-item instrument and the same 21 open-ended questions were used for data collection. The data collected were analyzed using descriptive statistics and two-way analysis of variance, and the descriptions were grouped by meaning. The participants frequently experienced unintended adverse consequences that resulted from EMR use, and their experiences were organized into 11 subgroups under four dimensions of the unintended consequences instrument including the malfunction and inefficient design of EMR screens dimension (two groups), extra work from EMR implementation dimension (three groups), EMR incompatibility and changes in the prescription pattern dimension (three groups), and patient safety and EMR dependence (three groups). Successful implementation of EMRs is possible when unintended adverse consequences identified by the users are corrected and EMRs are tailored to user needs. Healthcare organizations should provide administrative support, timely technical remedy, and user training to increase user acceptance on a system.
