- Distributes data across a decentralized network, making it resistant to unauthorized modifications or deletions
- Enables secure and auditable tracking of data provenance and access history
Patient-Centric Care and Consent Management
- Patient-centric care focuses on empowering patients to actively participate in their own healthcare decisions and management
- Involves providing patients with secure access to their health information, enabling them to share data with healthcare providers and researchers as desired
- Supports personalized treatment plans, shared decision-making, and patient engagement in health management
- Consent management in healthcare refers to the process of obtaining and managing patient consent for the collection, use, and sharing of their health information
- Ensures patient privacy rights and control over their health data
- Blockchain-based consent management systems can provide a transparent and auditable record of patient consent, allowing for granular control over data access and sharing permissions
Smart Contracts in Healthcare
Applications and Benefits of Smart Contracts
- Smart contracts are self-executing contracts with the terms of the agreement directly written into code on a blockchain network
- Automatically enforce contract terms and conditions without the need for intermediaries
- Enable secure, transparent, and efficient execution of healthcare-related agreements and transactions
- Potential applications of smart contracts in healthcare include:
- Automating claims processing and payments between healthcare providers and payers
- Managing supply chain and inventory for medical devices and pharmaceuticals
- Facilitating clinical trial data sharing and patient recruitment
- Enabling secure and auditable data access control and consent management
- Benefits of using smart contracts in healthcare include:
- Reducing administrative costs and delays associated with manual processes and intermediaries
- Improving data security, privacy, and auditability through blockchain-based encryption and immutability
- Enhancing trust and transparency in healthcare transactions and agreements
- Enabling new models of patient-centric care and data sharing, such as patient-controlled health records and data marketplaces
Key Terms to Review (16)
Blockchain: Blockchain is a decentralized digital ledger technology that records transactions across many computers in such a way that the registered transactions cannot be altered retroactively. This feature ensures transparency, security, and trust among users without the need for a central authority. Its applications span various industries, enabling innovations in areas like finance, healthcare, and supply chains.
Data Integrity: Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle. It ensures that data remains unaltered during storage and transfer, providing a foundation for trust in digital records. Maintaining data integrity is crucial across various systems, as it prevents unauthorized modifications and helps in complying with regulations.
Data sovereignty: Data sovereignty refers to the concept that digital data is subject to the laws and regulations of the country in which it is stored or processed. This idea is critical in industries like healthcare, where sensitive information, such as patient records, must comply with specific legal frameworks and privacy regulations to ensure the protection of individual rights and maintain trust.
Electronic health records: Electronic health records (EHRs) are digital versions of patients' paper charts, providing a comprehensive, real-time view of a patient's health information. They allow for the storage, retrieval, and sharing of patient data among authorized healthcare providers, enhancing communication and coordination of care while ensuring accuracy and security.
