Let's dive into what blockchain can do in the healthcare system and, of course, what it can do for each and every one of us affected.
Decentralised Electronic Health Records (EHRs)
Decentralised EHRs are digital health record systems that distribute and store patient data across multiple nodes or servers, i. e. the blockchain version of your health records. They have a number of advantages:
Improved Data Security
Decentralised EHRs use cryptographic techniques, such as encryption and digital signatures, to protect the confidentiality and integrity of health records. This makes it harder for unauthorised individuals or entities to access or tamper with sensitive patient information.
However, it's important to note that decentralised EHRs also come with their own challenges and considerations. Implementing and maintaining a secure decentralised system requires careful design, robust infrastructure, and adherence to privacy regulations.
Interoperability is a challenge in the current healthcare system, as different providers may use incompatible EHR systems. Decentralised EHRs based on standards such as HL7 FHIR (Fast Healthcare Interoperability Resources) can facilitate seamless data exchange between different healthcare providers, improving care coordination while maintaining security.
By empowering patients to control their medical data and share it with healthcare providers, blockchain technology fosters a more patient-centric approach to healthcare. This increased data ownership and control can lead to better engagement and understanding of their health, ultimately leading to improved health outcomes.
Also, patients can grant and revoke access permissions to healthcare providers or other entities, ensuring that only authorised individuals can view their records. This reduces the risk of data breaches and unauthorised access.
Supply Chain Management and Tracking
By leveraging blockchain's transparent and tamper-proof nature, pharmaceutical supply chains can be tracked from manufacturing to the end consumer. This traceability can help identify and eliminate counterfeit drugs, ensuring patient safety and protecting the reputation of the industry.
Medical Device Authentication
Blockchain can also be used to authenticate medical devices, ensuring that only genuine and approved products reach patients. This authentication can help reduce the risk of using counterfeit or substandard devices, which could lead to serious health complications.
Efficient and Transparent Supply Chains
Blockchain's ability to provide an immutable record of transactions can streamline the healthcare supply chain, reducing delays and increasing transparency. This can lead to more efficient processes, lower costs, and improved patient care.
Insurance and Claims Management
Smart Contracts for Policy Administration
Blockchain-based smart contracts can automate insurance policy administration, simplifying processes and reducing the potential for human error. This can result in faster and more accurate policy management, benefiting both insurance providers and policyholders.
Fraud Detection and Prevention
The transparency and security offered by blockchain technology can help insurance companies detect and prevent fraudulent claims. By maintaining an immutable record of transactions, insurers can quickly identify suspicious activities and take necessary actions to mitigate risks.
Streamlined Claims Processing
Blockchain's ability to automate processes can significantly reduce the time and effort required for claims processing. This can lead to faster reimbursements for policyholders and lower administrative costs for insurance companies.
