DHIS version 2.22 is out with a lot of great new features and improvements.

Log in with admin/district on the demo system.

Data elements and indicators app: A completely new app for data elements and indicators maintenance features a much slicker user experience, with on-the-fly search, “access” and “last updated” visible in the lists, a new group editor, and much better looks.

Integrated tracker analytics: Tracker-type data elements, attributes and program indicators can now be included in aggregate indicators. This allows for creating integrated analysis through indicators where e.g. the numerator is being collected in a program while the numerator is collected in an aggregate form. This means that you can produce integrated analysis without caring about whether the data comes from routine forms, anonymous events or tracking.

Multiple programs in favorites: Data elements and attributes from any number of programs can now be included in the same pivot table or chart favorite.

File cloud storage in tracker: The tracker capture and event capture apps now support file storage for data elements of type file. This allows you to use tracker as a document repository, and to upload documentation and files related to events or people. Files can be stored either on the Web server or sent directly to AWS S3 cloud storage.

Tracker data audit: Tracker capture and event capture now store the audit trail of changes to data and make it readily available by clicking on the audit icon next to each input field in the form. This is useful to view historical changes to information and a requirement in many settings where sensitive data is being stored.

Improved tracker capture: The tracker capture app has received a range of improvements.

- Yes/No fields are rendered as radio-buttons instead of drop-downs for faster data entry.

- The enrollment and active programs widget have been merged for better usability.

- Easy search for option sets: Option sets can be searched from within the data entry widget.

- Enrollments can be incompleted in order to change existing values.

- You can filter for people who have a scheduled event today.

- Events of repeatable program stages can be viewed and edited in a list.

- Tracker data element and attribute values can contain up to 50’000 characters.

- The widgets in the tracker dashboard displays a loading indicator until data is available.

- Whether to include due date input field can be configured per program.

- Whether to list people on the front page can be configured per program.

Encryption: Tracker now lets you encrypt identifiable / confidential information in the database. You can set a tracked attribute to “confidential”, which will encrypt the information you capture for it. This protects against attacks directly against the database. Note that due to the nature of encryption you cannot query or do analytics for encrypted attributes. Encryption requires some extra configuration which is outlined in the docs.

LDAP: DHIS 2 now supports authentication against an LDAP server. This is useful in order to centralize user credentials across multiple systems. The LDAP connection can be specified in the dhis configuration file. A DHIS 2 user account can be matched to a directory entry through the username or through an explicit “LDAP identifier” set for each user.

Integrated app store installation: The apps management app has been rewritten and now lets you install apps from inside your own DHIS 2 instance directly from the app store at dhis2.org/appstore. This means that there is no practical distinction between the core apps (apps being part of the DHIS 2 installation) and external apps (residing in the app store).

Demo | Screenshot

Approval workflows: You can now create data approval workflows where each defines a list of data approval levels. Several data sets may be associated with a data approval workflow. This implies that you can have multiple parallel approval workflows in the same system. As an example, health facility reporting may have to be approved at district and provincial level, whereas district population data might have to be approved at the national level only. Approval levels and workflows can be configured in the settings app.

Aggregate functions in surveillance rules: For validation rules of type surveillance you can now specify aggregate functions such as average, count, std dev and median. This is useful e.g. in order to identify disease outbreaks and ignore outliers or poor-quality data.

Docs

Organisation unit translations: You can now translate the names and short names of organisation units and have those names be reflected in the hierarchy.

Screenshot

Unique meta-data attributes: Meta-data attributes can now be unique, meaning the system will enforce uniqueness for the attribute values for each object type. This is useful as you can use attributes for various identifiers, e.g. personal identifiers and batch identifiers. Dynamic attributes are now also supported for option sets, options and resources.

Docs | Screenshot

Data value bulk delete: A new import strategy for deleting data values is supported in order to make it easier to delete bulks of data.

Docs | Screenshot

Analytical object deletion handling: Associations to pivots, charts and maps will be removed when deleting data elements, indicators, data sets and organisation units.

Screenshot

User replication authority: The ability to replicate users can be granted through a new authority “Replicate user”.

Screenshot

WEB API FEATURES

------

ADX data export: You can now export data in the ADX format natively using the dataValueSets Web API resource with content type application/xml+adx.

Docs

Dynamic identifier schemes: For data imports you can now specify unique meta-data attributes as identifier schemes. This implies that DHIS 2 can be used to store any number of sets of identifiers and map data to those during import. This is useful when DHIS 2 is used to integrate data from a large number of systems and each have their own sets of identifiers.

Docs

SMS: SMS can now be completely managed through the Web API, with new resources for sending and receiving SMS, starting and stopping the SMS service and configuration of SMS gateways. The system has now built-in support for five popular SMS gateway providers. The SMS services have been revamped and made more scalable.

Docs

App store: The contents of the DHIS 2 app store is available at the appStore resource, which also allows you to install apps from the app store with a POST request.

Docs

Field filter operators: A range of new field filter operators has been added, such as ^(like/ilike) to match from start of string and $(like/ilike) to match from end.

Docs

Tracker bulk deletion: Bulk deletion of events, enrollments and tracked entity instances are now supported through a new delete import strategy.


Docs

Async data value import: Data values can now be imported asynchronously through a new async parameter, meaning you can post a large import file and poll for the results rather than having the response block until the process is done.

Docs

Data pruning by org unit: Data, complete data set registrations and approvals can be removed by organisation unit through the maintenance/dataPruning resource.

Docs

Typed user settings: You can now set all user settings through the userSettings resource, including those of complex types.

Docs

Data value deletion: Data values can now more easily be deleted through a new delete import strategy, which lets you indicate explicitly that the posted data values should be deleted.

Docs

SERVER MANAGEMENT FEATURES

------

System read-only mode: You can now set the system to start in read-only mode which means that no database write-operations will be executed when the system starts and when people are loggging in. This is useful in order to run DHIS 2 on read-only database replicas for horizontal scaling purposes.

Docs

General configuration file: The DHIS 2 configuration file has been renamed to dhis.conf, and the configuration properties have been given general names, removing the association to the Hibernate framework.
