OHDSI/Achilles 1.3.0

Version 1.3.0

on GitHub

This is the July release of Achilles including the following changes:

Bugfixes

• R version was updated

Features

• new type of Heel output (NOTIFICATION) that is even less significant than WARNING
• rules are divided into DQ rules and model-conformance checking rules (in a rule comment (at this point))
• Heel rule output indicates in square brackets what type of DQ issue is being checked (e.g., plausibility)
• new rules were added (for example for unmapped data)
• new analyses (for v5 CDM) #125
• new concept of derived analyses (now also called measures). Derived measures have measure_id (similar to analysis_id) (but it is a string (and not integer)) #106
• derived measures can output float as output (not just integer) (such as ratios, percentages)
• allow rules to be simple (using derived measures) and thus applied to non CDM datasets (partially) #116
• new analysis going after concept_0 #72
• derived measure can be used for data quality assesment that is qualitative (and not mere warning) select * from achilles_results_derived For example select * from achilles_results_derived where measure_id = 'Provider:PatientProviderRatio' (compare data density between databases)

Examples of new rules outputs
