Blockchains Applications in Healthcare

  • A block chain is a database which is spread through a computer network. It is very hard to change when a record has been added to the chain. The network performs constant checks to ensure all the copies of the database are the same.
  • Block Chain has a wide range of healthcare applications and uses. The ledger technology makes it easier to securely transfer patient medical records, manages the supply chain of medicine and helps researchers in healthcare to unlock genetic code.

Block chain Medical Records Can Streamline Care and Prevent Costly Mistakes

  • Miscommunication between medical professionals usually costs the healthcare industry a staggering amount. The time consuming process of obtaining access to a patient’s medical records exhausts staff resources and delays patient care. Block chain-based medical records offers a cure for these ills.
  • The decentralized nature of the technology creates one ecosystem of patient data that can be quickly and efficiently referenced by doctors, hospitals, pharmacists and anyone else involved in treatment.


Block chain in healthcare examples include the following usage issues:

  • Problem: Patient Data Management
    The privacy of patient data is strictly governed by the Portability and Transparency Act of Health Insurance (HIPAA), and requires PHI to be fully safe. However, there is another PHI-related problem: often patients need to share their medical history with third parties (e.g. when they need to purchase particular drugs with pharmacies). So how can the block chain help secure data while simultaneously having partial access?
    Block Chain Based solution:
    A hash for each PHI block, along with a patient ID, is generated by the Block chain. Using an API, covered organizations may receive the information required without disclosing the identity of a patient. In the same manner, a patient will assess how to have access and whether this access will be either total or partial.
    In addition, if the patient is not aware about what he or she is doing a patient may create unique third parties who will have to give their permission to share the PHI.

  • Problem: Drug Traceability:
    One of the most serious problems in pharmacology is drug counterfeit. According to the Health Research Funding Organization (HRFO), approximately 10%-30% of drugs in developing countries are fake.
    Block Chain based solution:
    All block chain transactions are time-stamped and permanent, it is easy to recognize fraudulent drug dealers. Two forms of block chain exist: private and public. In order to ensure authenticity and the high quality of their drugs, trustworthy healthcare block chain companies must register their products in the private system. Central institutions are moderated by private block chains, and the fact that a single manufacturer or distributor has access to the so-called drug block chain is evidence of drug authenticity. This is where the transparency of the block chain comes in handy. The operational data is registered on the block chain until a drug is manufactured and passes from the supplier to the retailer. It makes it incredibly easy to verify the entire drug route, and at any time to determine all chain ties.
