|Initial Patient Population:||
Patients 18-50 years of age with a diagnosis of low back pain during an outpatient or emergency department visit
Equals Initial Population

Higher score indicates better quality
The outpatient or emergency department visit in the Initial Patient Population needs to occur during the first 337 days of the measurement period (337 days allows 28 days for the numerator event). This visit must be the first visit for low back pain during the measurement period.
- Copyright updated.
- eMeasure version number incremented.
- Introduced function 'satisfies all' to specify that qualifying events must meet all conditions from a set of conditions or 'satisfies any' to specify that qualifying events must meet at least one condition from a set of conditions to streamline expression logic.
- Introduced occurrencing on variables to enforce that the same instance of a clinical event is used throughout the measure when the logic within the variable does not limit the event to a single instance, e.g., FIRST or MOST RECENT.
- Introduced variable $LBPEncounter and $DiagnosisTraumaIVDrugNeuroImpairment to allow re-use of logical expressions and reduce redundancy/complexity.
- Replaced 'ORs' with 'Union of' operator.
- Replaced 'Patient Characteristic Birthdate' with 'Age at' operator.
- Replaced 'starts before or during' (SBOD) with 'starts before end of' (SBE).
- The top level logical operator for the Numerator Exclusions, Denominator Exclusions, Denominator Exceptions, and Measure Population Exclusions defaults to 'OR'.
- Updated Denominator Exclusion for active diagnosis of trauma, IV drug abuse, and neurologic impairment. Original logic stated that these denominator exclusions were valid if any occurred '<=365 day(s) starts before end of 'Measurement Period'.' The logic now states that these exclusions are valid if any should occur '<=365 day(s) starts before or concurrent with start of Occurrence A of $LBPEncounter.'
