This project contains libraries for parsing HQMF documents and parsing MAT packages.
To load measures from a MAT package file into the measure model, use the Measures::CqlLoader class. It can be used to create an array of measure models. For a composite measure, the array will contain the component measures and the last element will be the composite measure. For a non-composite measure (most measures), the array will contain one item.
Example measure loading:
# Set the VSACValueSetLoader options; in this example we are fetching a specific profile.
vsac_options = { profile: 'MU2 Update 2016-04-01' }
# Set the measure details. For defaults, you can just pass in {}.
measure_details = { 'episode_of_care'=> false }
# Load a MAT package from test fixtures.
measure_file = File.new File.join('some/path/CMS158_v5_4_Artifacts.zip')
# Initialize a value set loader, in this case we are using the VSACValueSetLoader.
value_set_loader = Measures::VSACValueSetLoader.new(vsac_options, get_ticket_granting_ticket)
# Initialize the CqlLoader with the needed parameters.
loader = Measures::CqlLoader.new(measure_file, measure_details, value_set_loader)
# Build an array of measure models.
measures = loader.extract_measuresNote that a different value set loader could be passed in; for example if you had a file containing value sets you could create a loader that read the value sets from file instead of fetching them from VSAC.
