Written by Alex Morphy,

Electronic medical records (EMRs) have revolutionized the way healthcare providers manage, gather, and distribute patient data. Medical practices can now store vast quantities of confidential information online rather than on paper and retrieve it at any time. But digital records have their problems of security. Patient information can be shared as a result of cyberattacks, unauthorized access, data breaches, and accidental disclosure.

What is Data Encryption?

Data encryption is a process of making data hard to read or incomprehensible from plaintext (readable) to ciphertext (encoded). The encrypted information can only be converted back into its original form by someone with the appropriate decryption key.

In healthcare, encryption can be used for patient data security when it’s stored and when it’s transferred between systems.

Encryption at Rest

Encryption at rest is the security method used to protect information, whether it’s on the device, on the server, on the database, or on the cloud. Once an unauthorized user accesses a storage system, files are much more difficult to access without a decryption key.

If a health care organization stores patient data in a database, for instance, encryption can help protect the patient information stored on the database if the storage device is compromised or stolen.
Encryption in transit

Security of data as it is being transferred from one location to another. Healthcare providers often share patient data with other authorized individuals, such as other healthcare providers, pharmacies, insurance companies, and laboratories, among others, between computers, servers, and the like.

Secure encryption protocols help to ensure that the data is protected from being accessed while in transit over networks.

Why is it important to use encryption with an electronic medical record system?

Some of the more subtle information relating to the people is included in EMRs. Personal information, such as names, addresses, medical history, diagnoses, treatment details, insurance information and more can be found in a single patient record.

This security breach can wreak a great amount of harm on the patient and the health care organization.

Minimizing the risk of data breaches

Healthcare organizations often hold all the trimmings for cybercriminals to strike because of the information they typically store. Encryption is another level of security because if it is lost or stolen or intercepted, it is not as easy to use.

Though encryption is not a solution for all cyberattacks, it does limit the potential impact if a cyberattack succeeds in gaining access to sensitive information.

Protecting Patient Privacy

Doctors and other health care professionals are expected to keep patient information confidential. Robust encryption methods can help organizations protect this data from unauthorized access.

Encryption makes patient information more difficult for an unauthorized user to access or utilize.

Supporting HIPAA Compliance

The Health Insurance Portability and Accountability Act (HIPAA) sets forth regulations for healthcare companies in the United States dealing with protected health information (PHI). HIPAA provides guidelines to protect private patient information.

Encryption is a key element of an overall strategy of securing electronic PHI. When selecting an EMR system, organizations should look for a solution that has robust security measures and encryption features. Healthcare providers can also conduct a search for the best HIPAA-Compliant EMR software solutions and find one that meets their privacy and security needs when researching options.

How Encryption is used in EMR Systems.

There are multiple ways in which modern EMR platforms can provide data security across the healthcare data’s lifecycle.

Security of Stored Patient Data

Medical professionals typically keep extensive patient records in data centers and cloud systems. This data can be protected from unauthorized access using encryption.

Another way cloud-based EMR systems can protect information stored on their servers is through the use of encryption. But for healthcare organizations, it is important to consider a vendor’s security measures and its implementation of encryption.

Providing secure remote access

The use of remote access in the healthcare sector is increasingly prevalent. Authorities and doctors may require accessing information from patient records on multiple devices or places.

Encryption may be used to help secure information during remote sessions, and should be used in conjunction with other security measures like multi-factor authentication, access controls and secure device management.

Access Controls

Patient information must be accessed by only authorized employees. Role based access controls can restrict access to information based on users’ role in order to allow access to only the information that they need to do their job.

Regular Security Updates

The vulnerability in software can give rise to an opportunity for attackers. Security risks can be minimized by maintaining EMR platforms, operating systems, and connected devices up to date.

Employee Security Training

There is still the possibility of human error as a security threat. Similar to the other characters, regular training of healthcare employees should be conducted regarding password security, phishing attacks, social engineering, and handling patient information.

Let’s look at some of the things that healthcare organizations should consider.

Healthcare providers need to consider factors beyond mere functionality when choosing an EMR system. Security should be an important consideration throughout the decision-making process.

Organizations should seek out information from vendors on encryption, data storage methods, access control, authentication, backup, and data incident response. They should also assess if the vendor has the necessary documentation and agreements to deal with protected health information.

 

Conclusion

Encryption is one of the fundamental technologies used to defend electronic medical records in the modern digital healthcare surroundings. Encryption not only protects data while it is being transmitted but also when it is stored, helping to minimize the chances of unauthorized access or data breaches and contributing to overall patient privacy and security measures.
