<p>Smart Contracts have played a significant role in healthcare applications and have been used for various purposes, such as the secure and decentralized way of managing patient data, monitoring medication adherence, or automating insurance claim processing. Developing decentralized healthcare applications (DApps) powered by blockchain technology could revolutionize the healthcare industry. Quality of service (QoS) measures the level of service quality that a system can provide to its users. In healthcare, QoS requirements may include availability, reliability, performance &amp; security. However, the QoS of smart contracts is crucial for the success of these DApps. The present research has considered the quality of services and conventional healthcare solutions for smart contracts. In this paper, we have proposed a novel approach to enhance the QoS of smart contracts in healthcare DApps. By conducting thorrow literature review to understand the current state of the art and identify existing solutions, research question is developed and methodology is defind accordingly to evaluate the effectiveness of current approach. The results have shown that current approach can significantly improve the QoS of smart contracts in healthcare DApps, thereby improving patient outcomes and reducing costs.</p>
