The main goal of this study is to discuss the need for interoperability of Electronic Health Records (EHR) and Internet of Things (IoT) and highlight how the Health Level 7 (HL7) interoperability standard could be the solution to bringing the benefits of these disparate systems together for the benefit of all patients. This study conducted a thorough literature search and analyzed the EHR and HL7 critically. The results highlight that the health care industry is experiencing unprecedented changes, with a considerable increase in the use of electronic/automated systems that can make considerable improvements in the quality of life of patients around the world. However, to achieve such benefits, these systems need to be able to communicate freely with each other. Thus, more emphasis is made on improvising the health care systems such that they provide maximum benefits for the patients.
