EHR and Bioinformatics: Blockchain to the rescue

By Sairam Bollapragada (Prof.) & Shravani B

The convergence of electronic health records (EHRs) and bioinformatics has led to significant advancements in healthcare. However, the integration of sensitive patient data with complex computational tools also introduces new cybersecurity vulnerabilities. Protecting patient data and ensuring the integrity of bioinformatics research is paramount to maintaining public trust and advancing healthcare.

1.?Growing Research Needs Through Bioinformatics for Biotechnology

Bioinformatics plays a crucial role in driving innovation and addressing pressing healthcare challenges. Some of the growing research needs include:

a.?Personalized Medicine: Bioinformatics helps lessen the number of trials & errors and supports the development of pharmacogenomics, where drugs are tailored to a patient's unique genetic profile, improving efficacy and reducing side effects.

b.???? Drug Discovery and Development: By utilizing bioinformatics, researchers can simulate molecular interactions and use the huge library of compounds present to accelerate the drug discovery process. Computational models also help predict the bioavailability, toxicity, and off-target effects of potential drugs, making clinical trials easier and quicker.

c.?Disease Diagnosis and Prognosis: Advanced bioinformatics algorithms can integrate genetic and clinical data to improve the accuracy of disease diagnostics and ML models can be used to detect patterns in data that might be missed by traditional methods, offering earlier detection of diseases like cancer.

d.?Epidemiological Studies: The power of bioinformatics in handling large datasets is crucial in tracking disease outbreaks and understanding the mutations of the pathogen causing it.

e.?Clinical Genomics: In clinical genomics, bioinformatics tools are essential for interpreting vast amounts of genomic data. These tools will help in identifying clinically relevant genetic variants associated with inherited diseases, which can help us have more precision in treatment. Moreover, it lets us integrate patient data with global genetic databases, enhancing the ability to diagnose rare genetic disorders and advancing personalized healthcare approaches.

For all the above areas to be taken up in the research labs, the seed point for all information is still the EHRs and millions of such atomic records which when collated and integrated, can bring out the inferential patterns so to chalk out further research progression. Hence the criticality of the data quality, authenticity of sources and their accuracy amongst many other parameters.This brings us then to the most critical component of data security. Secure data coming from authentic sources can be a strong positive catalyst and hence the emphasis on the same!

2.????? Data Security and Its Significance

While we speak of EHRs being so convenient for sharing and establishing a research base for a wider population sample, we need to be absolutely sure of the data security threats as of utmost importance in the context of EHR and bioinformatics.

The healthcare industry continues to be a primary target for cyberattacks, with 83% of healthcare organizations reporting at least one data breach in the last two years . In 2023 alone, healthcare data breaches affected over 42 million individuals in the U.S. This highlights how critical it is to fortify data protection measures to ensure both patient privacy and trust.

Protecting patient data not only ensures privacy and confidentiality but also maintains public trust and compliance with regulatory requirements.

Data protection laws like the Health Insurance Portability and Accountability Act (HIPAA) in the U.S. impose strict security guidelines on EHR management. Non-compliance can result in heavy fines. In 2021, for instance, HIPAA fines totaled over $13 million, underscoring the financial burden of negligence in maintaining security standards .

A breach of patient data can have severe consequences, including financial loss, reputational damage, and legal liabilities.

Recent case studies demonstrate the impact of such breaches. For example, the 2021 Scripps Health data breach resulted in a $112 million financial loss, including the costs of system recovery and loss of revenue due to disrupted services . Additionally, lawsuits stemming from breaches can take years to resolve, and the average cost of a healthcare data breach has reached $10.93 million, one of the highest across all industries.

3.?Cybersecurity Vulnerabilities

Let us dig deeper into the vulnerabilities that needs mention on the darker side of the spectrum:

• Data Breaches: According to a report by Blue-chip’s Cost of a Data Breach Study, the average cost of a data breach in healthcare reached $10.05 million in 2023. This highlights the significant financial and reputational risks associated with data breaches in the healthcare industry.
• Data Manipulation: Malicious actors can alter or delete medical records, compromising patient care and legal evidence.
• Ransomware Attacks: Ransomware attacks have become increasingly prevalent in recent years. Healthcare organizations are particularly vulnerable due to the critical nature of their services and their reliance on digital systems.
• Supply Chain Attacks: Vulnerabilities in third-party software or hardware used in EHR systems can be exploited to gain unauthorized access.
• Insider Threats: Employees with access to EHRs may misuse or steal data for personal gain or malicious purposes.

4.?Blockchain for Enhanced Data Security and Trust

Blockchain technology, known for its immutability and transparency, offers a promising solution to address many of the cybersecurity challenges faced by EHR and bioinformatics systems. Here are some potential use cases:

• Secure Data Storage: Blockchain can provide a decentralized and tamper-proof ledger for storing patient data, ensuring its integrity and preventing unauthorized access.
• Consent Management: Blockchain can be used to create a transparent and verifiable record of patient consent for data sharing and usage, enhancing patient privacy and control.
• Data Sharing: Blockchain can facilitate secure and efficient sharing of patient data among healthcare providers and researchers, while maintaining privacy and confidentiality.
• Supply Chain Transparency: Blockchain can be used to track the provenance of medical devices and pharmaceuticals, ensuring their authenticity and preventing counterfeit products from entering the supply chain.
• Clinical Trial Data Management: Blockchain can provide a secure and transparent platform for managing clinical trial data, reducing the risk of data manipulation and improving the efficiency of clinical research.

By integrating blockchain technology into EHR and bioinformatics systems, healthcare organizations can enhance data security, improve patient trust, and drive innovation in healthcare research.

5.?Sample Reference Use Cases

Let us quote below top 5 simple use cases in the above context below where blockchain can prove beneficial:

1. Secure Patient Data Storage: Blockchain's immutability and transparency can provide a robust solution for storing sensitive patient data, ensuring its integrity and preventing unauthorized access.
2. Consent Management: Blockchain can create a verifiable record of patient consent for data sharing and usage, empowering patients and enhancing privacy.
3. Interoperable Data Sharing: Blockchain can facilitate secure and efficient sharing of patient data among healthcare providers and researchers, improving care coordination and research outcomes.
4. Supply Chain Transparency: Blockchain can track the provenance of medical devices and pharmaceuticals, preventing counterfeit products and ensuring their authenticity.
5. Clinical Trial Data Management: Blockchain can provide a secure and transparent platform for managing clinical trial data, reducing the risk of data manipulation and improving the efficiency of research.
