IoMT sensor nodes, Internet of Things (IoT) wearable medical equipment, healthcare facilities, patients, and insurance firms are all increasingly being included in IoMT systems. Therefore, it is difficult to create a blockchain design for such systems, since scalability is among the most important aspects of blockchain technology. This realization prompted us to comprehensively analyze blockchain-based IoMT solutions developed in English between 2017 and 2022. This review incorporates the theoretical underpinnings of a large body of work published in highly regarded academic journals over the past decade, to standardize evaluation methods and fully capture the rapidly developing blockchain space. This study categorizes blockchain-enabled applications across various industries such as information management, privacy, healthcare, business, and supply chains according to a structured, systematic evaluation, and thematic content analysis of the literature that is already identified. The gaps in the literature on the topic have also been highlighted, with a special focus on the restrictions posed by blockchain technology and the knock-on effects that such restrictions have in other fields. Based on these results, several open research questions and potential avenues for further investigation that are likely to be useful to academics and professionals alike are pinpointed.

When it comes to the use of the Internet of Things (IoT), the healthcare sector is set to become the next frontier of the digital revolution thanks to the Internet of Medical Things (IoMT). Due to their weight, importance, and sensitivity, these files must be protected in the strictest manner. Now that blockchain is becoming more widespread, scientists are concentrating on how to use blockchain tactics within healthcare management to improve data security. Nevertheless, owing to the differing needs of these two technologies, such integration is exceptionally complex and demanding. In order to help users, take full control of their data, this study provides an overview of the current state of blockchain platforms for the IoMT by focusing on the difficulties presented by combination systems. This article will examine blockchain's use in healthcare IoT, including supply chain transparency, health data arrangement, smart contracts, and IoT security for remote monitoring. The final portions focus on challenges and potential developments in the future.
