Evaluation of analytical studies of critical pathway variances in Japan.

In the last 10 years (1994-2004), the contents of original papers that examined critical pathway variances were analyzed. The results revealed that many research achievements were not applied to practically improving path variances as a result of insufficient coding of variances, and the use of coded data for statistical tests was limited. In order to obtain scientific evidence for evidence-based nursing, it is necessary to actively plan a research design for intentionally analyzing variance.

Nurses' Actual Usage of EMRs: An Access Log-Based Analysis.

Access logs for electronic medical records (EMRs) are a useful source of data for understanding how nurses' perform their duties. The purpose of this study was to understand how nurses' used an EMR system, by inspecting and analyzing from one week EMR access logs (394,708) of accessing 'outcome Input' screen. Anytime day and night, nurses accessed 'outcome Input' screen. Viewing and information input obtained from observations, in order to monitor patients' conditions over tasks such as keeping nursing records.
