Introduction: A hospital information system (HIS) is a comprehensive, integrated information system designed to manage the administrative, financial and clinical aspects of a hospital. As an area of medical informatics, the introduction of a HIS into a hospital was purported to reduce the time spent on administrative and clinical activities by electronic data processing. However, adoption has been slow, and a key concern has been that staffs will require more time to complete their work using HIS. And also Most of available HIS have lots of deficiencies in data gathering, so hospital managers decided to keep their paper records and same time use HIS. Most previous studies addressing this issue have been done with concentration on clinical staff activities.

Methods: Comparative observational of the impact of a HIS on Medical Records Department time in four units: Admission Discharge and Transfer/ADT, Medical Filing and Retrieval, Medical coding/billing, and Medical Statistics. Measurements: We used a time-motion method to measure staff time spent in predefined activities. Medical Records staff monitored while using HIS and paper based system. 15 clerical medical records staff were observed treating 300 documents while still using paper-based records, and same persons were observed treating 400 patients’ records with HIS.

Results: Following HIS implementation, the use of the computerized system decreased the average total workload by 61.35% (from 66.41 to 23.93 m).

Conclusion: Hospital Information System (HIS) reduces three nonclinical activities time noticeably which is vital to decision making and plays a crucial role in the success of the organization.

The  most recent editorial (June 2021)

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

An editorial by Dr. Mehrdad Jalalian

Read more.

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
