The impact of physician order entry on nursing roles.

This study examines the impact of physician order entry (POE) on nurses perceptions of work, quality of care, and nurse/physician communication. Four hospitals that have implemented a computerized order-entry system with POE were compared with four similar hospitals using the same computerized system with clerk order entry only. Three factors were extracted from the 29 item survey using principal component extraction with varimax rotation that accounted for 16.5%, 12.4% and 8.7% of the variance respectively. Three scales were constructed from these factors measuring perceptions of impact of the information system on the quality of care, job, control, and nurse/physician communication. Nurses working in the POE environment rated their computer system as having greater impact on the quality of care and lower ratings of perceived control than those working in non-POE environments. No differences were found between nurses working in POE environments and those working in POE in terms of their ratings of frequency of contact and ease of access to physicians.
