In addition to the web version, NextCloud offers desktop applications for Windows, Mac OSX, and Linux. It also provides mobile apps for Android, iOS, and Windows mobile.

NextCloud for Healthcare

1- Cloud DICOM viewer:

With the DICOM viewer application, available for one-click installation from the NextCloud AppStore, you can access a full-featured cloud DICOM viewer with syncing capabilities, mobile apps, team and multi-user functionality, and powerful chat/groupware apps.

A basic NextCloud installation provides all the necessary features for file sharing, including a PDF file viewer, file tagging, folder management, image viewer, file permissions, public file sharing, and contact management. However, system administrators can browse and install hundreds of other applications to use as they see fit for their teams. These include collaborative document writing tools, security and encryption packages, and antivirus scanners for files.

4-PHR  " Personal Health Records "  for patients and families:

Personal Health Records are basic apps built to help the patient keep record of his medical records securely.

5- Communication platform and Groupware:

5-Email apps:

 There are several email apps provided in NextCloud App store which make it easier for teams to use NextCloud email for work emails.

NextCloud community

NextCloud has a strong community of developers, users, and open-source supporters. It offers enterprise services to various industries, including education, healthcare, finance, law, manufacturing, and construction. NextCloud is becoming more popular in the open-source and enterprise worlds, showing it is a reliable choice.

NextCloud Security

Nextcloud provides both end-to-end encryption and server-side encryption for files, but this can slow down the system. Nextcloud also offers powerful password options for system administrators to enforce strong passwords and check them against breached passwords worldwide.

The Nextcloud App Store has many security apps and extensions, including an Antivirus app, a Two-factor authentication app, Brute-force settings for Whitelist IPs, Login restriction to certain IPs, Ransomware protection, and file recovery. While Nextcloud itself provides secure features, these additional security measures can further enhance its security capabilities.

NextCloud for Developers

NextCloud provides developers with rich and necessary documentation for creating applications on top of NextCloud and uploading them to the NextCloud AppStore.

Recently, NextCloud released an industrial analysis for healthcare usage. The analysis compares public and private cloud systems and emphasizes the necessity of using a private cloud with full control over source code, updates, encryption, and extensions.

While there are many private, open-source, and free clouds available for the healthcare industry, the benefits of using a private cloud are obvious. So, what makes NextCloud different?

  • Adherent to the healthcare standards
  • Committed to provide high security standards
  • Developer friendly
  • Provide solid platform for building cloud apps which can be extended as EMR, Cloud DICOM server
  • Integration with other services

Currently, there is a full-featured DICOM viewer app that is the first and most popular medical/healthcare app for NextCloud. However, in the future, we would like to see more apps from the community, such as an EMR (Electronic Medical Records) or a dedicated PHR for patients, built on top of NextCloud.
