Description
Summary:	Rationale, aims, and objectives Time is an important element in medical data. Physicians record and store information about patients' disease progress and treatment response in electronic medical records (EMRs). Because EMRs use timestamps, physicians can identify patterns over time regarding a patient's disease and treatment (eg, laboratory values and medications). However, analyses of physicians' use and satisfaction with EMRs have focused on functionality, storage, and system operation rather than the use of time‐oriented information. This study aimed to understand physicians' needs regarding time‐oriented patient information in EMRs in clinical practice. Methods The reliability and validity of the items in the questionnaire were evaluated in 87 physicians at a national university hospital. Internal consistency was satisfactory (Cronbach alpha coefficient, 0.87). Results Four dimensions were identified in exploratory factor analysis. Correlations between the 4 dimensions supported the construct validity of the items. Scores of time‐oriented patients' medical history in the 4 dimensions showed a significant association with physician age. Based on confirmatory factor analysis, associations were significant and positive (P < .001). In terms of the needs of physicians regarding time‐oriented patient information in EMRs, both time‐oriented treatment results followed by time‐oriented team information had significant positive associations. Conclusion Our study suggests that 4 specific time‐oriented patient information factors in EMRs are needed by physicians. Exploring physicians' needs regarding patient‐specific time‐oriented information may provide a better understanding of the barriers facing the adoption and use of EMRs (eg, decision‐making and practice safety concerns) and lead to better acceptance of EMRs in physicians' clinical practices.
