Class Method Details

.select_code(oid, value_sets) ⇒ Object

Select the relevant value set that matches the given OID and generate a hash that can be stored on a Record. The hash will be of this format: { “codeSystem” => “code_set_identified”, “code” => code }

Parameters:

  • oid (String) —

    The target value set.

  • value_sets (Hash) —

    Value sets that might contain the OID for which we’re searching.

Returns:

  • A Hash including a code and code system containing one randomly selected code.

def self.select_code(oid, value_sets)
  codes = select_codes(oid, value_sets)
  code_system = codes.keys()[0]
  return nil if code_system.nil?
  {
    'code_system' => code_system,
    'code' => codes[code_system][0]
  }
end

.select_codes(oid, value_sets) ⇒ Object

Select the relevant value set that matches the given OID and generate a hash that can be stored on a Record. The hash will be of this format: { “code_set_identified” => [code] }

Parameters:

  • oid (String) —

    The target value set.

  • value_sets (Hash) —

    Value sets that might contain the OID for which we’re searching.

Returns:

  • A Hash of code sets corresponding to the given oid, each containing one randomly selected code.

end

.select_value_sets(oid, value_sets) ⇒ Object

Filter through a list of value sets and choose only the ones marked with a given OID.

Parameters:

  • oid (String) —

    The OID being used for filtering.

  • value_sets (Array) —

    A pool of available value sets

Returns:

  • The value set from the list with the requested OID.
