Blockchain also empowers patients with enhanced control over their medical data. Traditional practices typically see healthcare providers maintaining patient records, often limiting patient involvement in data access decisions. Blockchain technology, through its decentralized nature and cryptographic features, allows patients to dictate who can view their health records. Utilizing private keys, which serve as digital signatures, patients can selectively grant or revoke access to portions of their medical history.

Traditional healthcare systems, often reliant on manual data entry and paper documentation, are prone to human error, billing inaccuracies, claims processing delays, and verification complications. Adopting blockchain technology can significantly reduce administrative burdens within the healthcare sector. Blockchain’s potential for task automation within the industry enhances efficiency and diminishes the prevalence of inaccuracies and fraud, which are common issues in conventional healthcare frameworks. The Federal Bureau of Investigation estimates that fraudulent billing accounts for 3% to 10% of total healthcare expenditures, contributing to inefficiency, elevated healthcare costs, and wastage. Blockchain technology can activate automated processes through smart contracts, which execute actions upon meeting specific criteria, thus eliminating the need for manual oversight. For instance, in the context of insurance claim processing, smart contracts on a blockchain can autonomously validate a claim once all requisite conditions are satisfied, streamlining the process and expediting settlements.

Blockchain’s implementation in healthcare also supports automated billing procedures. When a patient undergoes treatment, the associated transaction is instantaneously logged on the blockchain, enabling real-time billing and minimizing error or overcharge risks.

Lastly, blockchain plays a pivotal role in securing clinical trials and research endeavors. Informed consent is a fundamental aspect of clinical trials, requiring secure and accurate documentation of a patient’s agreement to participate in a study. Clinical fraud often involves the falsification of patient consent or the manipulation of consent forms, which compromises trial integrity and breaches ethical norms. The immutable ledger characteristic of medical blockchains is instrumental in preserving the authenticity and provenance of clinical trial data. Its unalterable nature makes blockchain an ideal medium for recording patient consent, maintaining precise trial records, and safeguarding against fraudulent activities.
