This review aims to review the benefits and effects of health information technology on health care system. Therefore, a Literature search was performed in the following databases: Cochrane library; PubMed; MEDLINE; CINAHL, for all relevant articles published up to 2022. To better understand why physicians and nurses utilize a certain health information or communication technology (e.g., CPOE, pager, email), we will employ a specialized interview approach called as think-aloud in conjunction with shadowing to examine their communication practices. During the course of action, the think-aloud technique entails asking participants what they are thinking and feeling as they communicate about patient care. This strategy reveals the difficult-to-obtain meanings underlying acts and will provide us deeper insight into communication strategies and workplace relationships.
