Currently, cross-institutional data sharing does not exist in the US healthcare system due to multiple challenges like high third party costs, lack of transparency and inadequate auditing. Personal health records are seldom with the individual patients as they are maintained by the healthcare institutions and healthcare payers. So, without the implementation of blockchain technology in healthcare, availing seamless medical care across the country is almost impossible.
Adding to this, most healthcare organizations even delete patients’ medical records after a certain period of time due to regulatory requirements and high cost of maintenance. Hence, after that particular time period, the chances of accessing personal health records are almost nil as it would be permanently erased.
