Background: The field of medicine has been influenced by the growth and development of information systems such as the Computerized Provider Order Entry (CPOE) System. 
Objective: This study aimed to evaluate the usability of CPOE systems for electronic prescription in Tehran, Iran. 
Methods: This was an evaluation study conducted in 2017. The research population consisted of the CPOE systems used in hospitals of Tehran (Iran) and nurses who had access to, and used, the CPOE systems. Five hospitals with CPOE systems were included in the research sample. The data were collected using a questionnaire, and included a total of 50 questions. The questionnaires were distributed among 254 nurses who were the users of the systems. Data analysis was performed by IBM-SPSS version 21, using independent-samples t-test. A p-value of ≤0.05 was considered statistically significant.
Results: Among the four aspects assessed, the “user-friendliness” (3.87±0.59) had the highest mean score. The lowest mean score (2.01±0.58) was related to the “decision support” feature of the systems. The highest and lowest mean scores for “prescription support” criterion belonged to system E (3.26±0.23) and system C (1.90±0.16), respectively. There was a statistically significant difference between the usability of the systems used in the private and the public hospitals (p<0.001). It was found that the CPOE systems in private hospitals had a higher level of usability (3.42+0.10) compared to those in public hospitals (2.91+0.25). 
Conclusion: Two main functions of the studied CPOE systems i.e., decision support and prescription support should be developed to make electronic prescription safer and more intuitive. Addressing usability aspects of CPOE systems in practice could improve the usability of these systems for prescription.

Ethics of Publishing Case Reports: Do We Need Ethics Approval and Patient Consent?

An editorial by Dr. Mehrdad Jalalian

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.


To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
