How Blockchain Technology Will Improve Mobile Healthcare

The key concerns of healthcare management today are data processing and data security. Patients don’t have full ownership of their medical records, and are unable to control how their information is updated. There isn’t enough transparency to the process. There are also significant concerns related to data security, especially in the areas of personalized medicine and the rise of wearables. Patients and medical staff need secure and straightforward ways to record data, send it over networks, and receive advice without security concerns. Blockchain technology can help solve these problems. Introduced in 2008 as a means of recording cryptocurrency transactions, blockchain is a distributed cloud-based ledger that offers the ability to verify the origin of data and prevent breaches. When a user wants to make a transaction, they issue a request signed with their private key. The network verifies its authenticity by using a public key. If the verification is successful, the transaction is broadcast to the network and included in a block. The network of “miners” solves the block to get a reward, and once the block is revealed, it is added to the blockchain, making it permanent. It’s impossible to introduce new information in a block unnoticed, because that would change the structure of the entire chain. This feature makes the system safe and transparent.

Preparing for the Future of Healthcare in Light of Automation

Article | February 24, 2020

Software automation accelerates processes and makes them more cost-effective, accurate, scalable, and measurable. But it also lets organizations coordinate and manage a collection of disparate systems according to business rules. These benefits offer enough value that automation is becoming an indispensable part of the enterprise toolkit. A 2019 Deloitte survey of 523 executives across industries found that 58% of organizations were already using Robotic Process Automation (RPA) and artificial intelligence (AI) combined. The top four objectives of this intelligent automation: increased productivity, cost savings, accuracy, and customer experience. How will this trend affect the healthcare job market? In the healthcare industry, examples include scheduling appointments, physician order entry, checking for allergies, ordering electronic prescriptions, validating a spreadsheet’s entries against data on a website, and manually transferring data from one system to another. Healthcare office workers tend to hate these tasks, which typically require very little decision-making, judgment, or creativity.

Artificial intelligence and healthcare

Article | March 10, 2020

When we imagine the future, we think about "The Jetsons" or "Back to the Future." Although we are not flying our cars or transporting instantly to any location at the push of a button, Artificial Intelligence (AI) permeates our lives. Think about the last time Netflix picked out your last binge marathon, Gmail finished your sentence or Siri created your grocery list. These are all examples of AI. Companies use Al to predict actions customers will take based on their habits. Al is also shaping the healthcare industry. In fact, according to Becker's Healthcare, Al will save healthcare $52 billion by 2021. Al bots track consumer health, enabling doctors to more easily access patients' health information. Apps and chat bots bridge the communication between the patient and the healthcare provider. Patients receive advice from their bedside and save time by using Al. Al takes a patient's health information and creates recommendations that can prevent further illnesses from occurring. A recent article provides insights on Al and data as a "what is next" for the communication industry.
