BLOCK CHAIN TECHNOLOGY AND THE MEDICAL FIELD

Ankle osteoarthritis is a condition that causes pain and stiffness in the ankle joint. Traditional treatments like joint fusion can limit mobility. An alternative procedure called ankle distraction arthroplasty has been gaining some traction, but how well does it hold up in the long term? 

A recent study by Greenfield et al. (2019) investigated this very question. They conducted a survival analysis of ankle distraction arthroplasty for ankle osteoarthritis. Their findings suggest that this procedure may be a viable option for some patients. 

Key takeaways from the study: 

  • Ankle distraction arthroplasty showed promising results, with an 84% survival rate at 5 years. This is better than some previously reported outcomes. 
  • The study also identified factors that can influence the success of the procedure. Avascular necrosis of the talus (bone death) was associated with a lower survival rate. Additionally, sex may play a role, with the study suggesting potential gender differences in long-term outcomes. 

What this means for patients: 

Ankle distraction arthroplasty offers a potential option for preserving joint mobility in patients with ankle osteoarthritis. This study provides valuable data for surgeons and patients to consider when making treatment decisions. 

Important to note: 

  • This was a retrospective study, meaning researchers analyzed past data. More robust research designs are needed to confirm these findings. 
  • The study involved a relatively small group of patients. Larger studies are necessary to draw more definitive conclusions. 

Overall, this research suggests that ankle distraction arthroplasty may be a valuable tool for treating ankle osteoarthritis. However, more research is needed to solidify its place as a standard treatment option.

Healthcare research initiatives are embracing industry 4.0 tools, facilitating more computer usage in their research efforts, and enabling better decision making processes to take place as discoveries are being made. In the computing realm, the blockchain technology, which facilitates decentralized data processing. How then, can the data be processed in order to facilitate these outcomes? 

Science is well known for cross functional uses. Many modern technologies that we rely on, such as GPS were developed by scientists and engineers in either army labs or NASA labs. If a discovery doesn’t make it on sphere, it can be repurposed for use in another realm. Interestingly, blockchain technology still has its origins in its original realm – Bitcoin and the financial sector. The underlying framework however, has usage in the medical realm in the facilitation of data transfer and processing. 

The medical industry prides itself on patient confidentiality. When it comes to general research, it is important for data to be properly interpreted and analysed. For patient data that is collected and analyzed for a cause, it will be important for critical information to be cleansed from the original data pool. With data sources ranging from healthcare institutions, insurance companies and third party sources, care must be taken to protect original patient data.  

As a decentralised ledger system, blockchain technology is a web-based framework that allows both patients and researchers to access a pool of information. Based on the system design and access, it will be possible to facilitate both user confidentiality and data exchange as transactions are processed.  With data transparency, it will be possible to facilitate the desired data pooling during clinical trials. With data traceability, data audits and information validity can be facilitated. With open data in systems, studies such as patient feasibility analysis and population studies can be conducted. 

Blockchain Technology 

As a distributed, public ledger of information linked in a peer-to-peer network of computers blockchain technology is key to healthcare data processing. Blockchain technology has various advantages including: decentralized management, immutable audit trail, data provenance, robustness, and improved security and privacy. 

Technically, a blockchain consists of ordered records. These are organized in an array, resembling that of a block. Each data block has a unique identifier that enables it to be traced. With this identifier, the history of transactions that the data block is involved in, can be tracked. Block connection is facilitated in a sequential fashion, and the resultant technology then derives its name. The beauty of blockchain technology is that connected blocks of data make it difficult to modify data in part of a sequence without modifying the entire block. 

The immutability of data, the phenomenon described above, is expected to improve patient care, by improving the current state of medical record management. From a peripheral perspective, organizations such as insurance companies that are linked to the hospital, can optimize their insurance claim process. Within the medical entities themselves, inhouse clinical and biomedical research can be accelerated. 

Additional Advantages of Blockchain Technology

While institution research, and medical innovation is key, with patients having the right to assign access rules to their medical data for a time that they determine, the patients can also log into the systems and collect their own medical data. This information will be critical in those instances where they feel like they might want a second opinion on their particular cases. Having the ability to access and utilize data will be a win for all. Dissecting the medical data, certain fields in the patient data will be tagged and stored in data blocks. Private data will be kept on internal files, while critical data such as patient allergy data, will be published on a public domain. 

With blockchain technology currently evolving, there are challenges to be met and overcome, before the technology can be readily accessible for mainstream or organizational healthcare applications. Once privacy, sharing access, network speed and other inherent challenges are dealt with, blockchain technology will become more widespread. As with all things that are new, there will be an initial phase of introduction, after which tweaking will facilitate the desired outcomes.
