Introduce
Although often associated with Bitcoin and other cryptocurrencies, blockchain technology has also been used to store and protect data in a range of different industries. Along with the charity and supply chain sectors, the healthcare sector is one of the most discussed use cases. But what aspects of blockchain make it suitable for the healthcare sector?
Benefits of using blockchain in the healthcare sector
Some of the features that allow cryptocurrency blockchains to act as a secure record for financial transactions are also applicable to storing medical data. Since most blockchains are designed as distributed systems that record and protect files through the use of cryptography, it is difficult to break or alter data without the approval of all those involved. other network participants. Therefore, immutability is one of the features that allows creating an indelible database for medical records.
Furthermore, the peer-to-peer architecture used in blockchains allows all copies of a patient's records to be synchronized with each other when updates are made, even though they are stored on separate computers. different. In fact, each network node keeps a copy of the entire blockchain, and they communicate regularly to ensure the data is updated and authenticated. Therefore, decentralization and data distribution are also important aspects.
It is worth mentioning that blockchains are distributed but not always decentralized (in terms of governance). Decentralization is not a black and white thing, it depends on how the nodes are distributed and on the overall architecture, distributed systems can create different levels of decentralization. In the healthcare sector, blockchains are often built as private networks, as opposed to public networks that are often used as cryptocurrency ledgers. While anyone can participate and contribute to the development of the public blockchain, private versions require permission and are managed by a smaller number of nodes.
Potential advantages of using blockchain in the healthcare sector
The power of blockchain goes beyond finance and is applicable in the healthcare sector as well. We can use blockchain to secure patient data and ensure the authenticity of pharmaceuticals. Below are some potential use cases that highlight how blockchain technology can revolutionize healthcare.
1. Enhance security
As mentioned, one of the most important use cases of blockchain in the healthcare industry is leveraging the technology to create a secure and unified peer-to-peer (decentralized) database. Thanks to the immutability of blockchain, data corruption is no longer a concern. Blockchain technology can be used to effectively register and track the medical data of thousands of patients.
Unlike traditional databases that rely on a centralized server, using a decentralized system allows data exchange with a higher level of security while also cutting down on administrative costs that the system incurs. current system imposed. The decentralized nature of blockchains also makes them less vulnerable to technical failures and external attacks that often compromise valuable information. The security provided by blockchain networks can be especially useful for hospitals, which often have to deal with hacker invasions and ransomware attacks.
2. Interoperability
Another advantage of blockchain-based medical records is the ability to increase interoperability between clinics, hospitals and other medical service providers. Technological differences in data storage systems often make it difficult for organizations to share documents.
However, blockchains can solve this problem by allowing authorized parties to access a unified database of patient files or even drug distribution records. So instead of trying to communicate with each other's internal memory, service providers can work together on a single memory.
3. Accessibility and transparency
In addition to simplifying the record sharing process, blockchain systems can also provide patients with a greater level of access and transparency regarding their own health information. In some cases, requiring confirmation of changes made to patient documents can ensure record accuracy. If used properly, this can provide an extra layer of security against human error and intentional tampering.
4. Reliable supply chain management
Blockchain can provide a reliable method of tracking pharmaceuticals through the entire manufacturing and distribution process, thereby cutting down on the common problem of counterfeit drugs. Combined with IoT devices used to measure factors such as temperature, blockchain technology can also be used to verify proper storage and transportation conditions or to authenticate drug quality.
5. Protection against insurance fraud
Blockchain can also be used to combat health insurance fraud, which is estimated to cost the US healthcare system more than $100 billion a year. Immutable records stored on the blockchain and shared with insurance providers can prevent some of the most common types of fraud, including paying for procedures that never took place and charging for unnecessary services.
6. Support for Clinical Experiment Activities
Another application of blockchain in healthcare is improving the quality and efficiency of clinical trials. Medical data on the blockchain can be used by laboratories to identify patients who may benefit from drugs being tested.
Such a search system could significantly improve clinical trial registration, as many patients never learn about relevant drug trials and, therefore, never have the opportunity to participate in them. they. Besides, when experiments are conducted, blockchains can be used to ensure the integrity of the data collected.
Challenges of applying blockchain to the healthcare sector
Implementing blockchain technology in healthcare is indeed promising, but it comes with some challenges. Let's dig into some of the concerns.
1. Compliance
Taking the United States as an example, healthcare companies interested in adopting blockchain technology are required to comply with applicable data regulations, such as the Information Disclosure and Accountability Act. Health insurance information of 1996 (HIPAA).
HIPAA outlines standards for storing, sharing, and protecting data in the healthcare sector. So, to be fully compliant, US-based companies will need to implement custom blockchain systems of record with enhanced security features and limited access capabilities.
2. Initial cost and speed
On the vendor side, blockchain solutions can require high initial investments, a reality that certainly prevents widespread adoption. Additionally, distributed systems tend to be significantly slower than centralized systems in terms of number of transactions per second.
A large blockchain network with many nodes will probably require more time to transmit and synchronize data when compared to centralized systems. This is especially relevant given the massive databases that will eventually need to store and track information on millions of patients. The problem gets worse for large image files, such as CT scans or MRI scans.
3. Education gap
The complexity of blockchain technology creates educational challenges in the healthcare sector. This understanding gap can lead to underutilization and improper implementation of blockchain solutions.
Ongoing training and education is needed to equip healthcare professionals with knowledge of potential use cases, appropriate implementation strategies, and awareness of evolving regulations and regulatory requirements. cyber threats.
4. Scalability
The massive amount of data generated by the healthcare sector poses a significant scalability challenge for blockchain networks. As data volumes increase, so do transaction times and operating costs on some blockchains.
This limitation can delay information retrieval or transaction verification, negatively impacting system efficiency and patient care. Additionally, these concerns could discourage healthcare organizations from adopting blockchain, halting innovations and advancements in the field.
5. Standardize data
Blockchain needs unified input data to promote effective communication and interoperability within the network. However, this is especially difficult in the healthcare sector, which has many types and formats of data.
Without a standardized data protocol, information exchange can lead to misunderstandings or errors, disrupting the system. Therefore, achieving data standardization without losing important details of health information poses a major obstacle to the use of blockchain in the healthcare sector.
summary
Blockchain has great potential for the healthcare industry, from securely managing patient data to enhancing transparency and safety. However, education gaps, scalability issues and current regulatory frameworks are some of the factors that need to be addressed. Balancing these barriers with the benefits of blockchain will require a meticulous and collaborative approach among all healthcare stakeholders.
