Introduction
Blockchain technology stands out as an innovation that has the potential to revolutionize the healthcare industry. With the advantages it offers in terms of security, transparency and efficiency of health data, it finds applications in many areas. Blockchain, which is used in a wide range of areas from electronic health records to the pharmaceutical supply chain, is being integrated into the healthcare sector with the aim of increasing the quality and accessibility of healthcare services.
The Power of Blockchain in Healthcare: Applications and Challenges
Electronic Health Records (EHR)
Blockchain makes electronic health records (EHR) more secure and transparent. By ensuring that patient data is stored securely, it also enables the fast and accurate sharing of data. Thanks to its decentralized structure, patient data is only accessible by authorized individuals. In addition, the accuracy of the data is maintained, as every change in data is recorded. Patients can determine who has access to their health data, giving them more control over it.
Pharmaceutical Supply Chain Management
The pharmaceutical supply chain is crucial for transparency and reliability. Blockchain enables medicines to be tracked from production to the end user. This prevents counterfeit medicines from entering the market and provides accurate information about the origin of medicines. By keeping a record of each batch of medicine, blockchain automates supply chain processes minimizing human errors. This increases overall efficiency and prevents counterfeiting.
Patient Authentication and Security
Blockchain technology secures patient authentication processes. Each patient’s unique digital identity is created and securely stored on the blockchain. This prevents identity theft. In addition, who can access patients’ data can be determined on the blockchain, which ensures data confidentiality. Data is prevented from being altered or manipulated, so that every piece of information remains accurate and secure.
Clinical Research and Data Management
Blockchain enables clinical research to be conducted in a more transparent and reliable manner. While facilitating data sharing between researchers, the accuracy of the data is guaranteed by blockchain. Furthermore, patients’ consent for data sharing can be recorded on the blockchain, which increases transparency. Every research process becomes traceable and auditable, ensuring security and transparency.
Health Insurance and Payments
Blockchain offers fast and secure solutions for health insurance transactions. Thanks to smart contracts, insurance transactions can be automated and payment processes can be accelerated. By verifying the accuracy of insurance claims on the blockchain, the risk of fraud is reduced. With the automation of these processes, cost efficiency is achieved, and manual processes are minimized.
Challenges Faced
In addition to the benefits that blockchain brings to the healthcare sector, some parts of the system may struggle to keep up with the radical changes it brings. First, the healthcare sector is highly regulated, so it may be difficult for blockchain applications to comply with these rules. In addition, the transparent nature of blockchain may pose challenges for the privacy of patient data. Integrating the technological infrastructure of existing healthcare systems into blockchain also poses a significant obstacle. In addition, the high costs and resource requirements of blockchain projects may make it difficult for some healthcare organizations to adopt the technology. Furthermore, the lack of adequate training and awareness of healthcare professionals about blockchain technology may hinder its widespread adoption.
