Description

This measure is used to assess the percentage of patients with a primary diagnosis of low back pain who did not have an imaging study (plain x-ray, magnetic resonance imaging [MRI], computed tomography [CT] scan) within 28 days of the diagnosis.

The measure is reported as an inverted rate (1 - [numerator/denominator]). A higher score indicates appropriate treatment of low back pain (i.e., the proportion for whom imaging studies did not occur).

Note from the National Quality Measures Clearinghouse (NQMC): For this measure, there are both Electronic and Hybrid Specifications. This NQMC measure summary is based on the Electronic specification. Refer to the original measure documentation for details pertaining to the Hybrid specification.

Rationale

Low back pain is a pervasive problem that affects two thirds of adults at some time in their lives. It ranks among the top 10 reasons for patient visits to internists and is the most common and expensive reason for work disability in the United States (U.S) (Jarvik & Deyo, 2002). Back problems are second only to cough among symptoms of people who seek medical care at physician offices, outpatient departments and emergency rooms (Center for the Advancement of Health, 2000).

Back pain is among the most common musculoskeletal conditions, afflicting approximately 31 million Americans, and is the number one cause of activity limitation in young adults. For most individuals, back pain quickly improves. Nevertheless, approximately 15 percent of the U.S. population reports having frequent low back pain that lasted for at least two weeks during the previous year. Persistent pain that lasts beyond 3 to 6 months occurs in only 5 to 10 percent of patients with low back pain (Lawrence et al., 1998). According to the American College of Radiology (n.d.), uncomplicated low back pain is a benign, self-limited condition that does not warrant any imaging studies. The majority of these patients are back to their usual activities in 30 days.

There is no compelling evidence to justify substantial deviation from the diagnostic strategy published in clinical guidelines, which indicate that for most patients with acute low back pain, diagnostic imaging is usually unnecessary. Although patients may have a perceived need for imaging studies, efforts to educate patients on appropriate indications for imaging are within a provider's capacity.

Primary Health Components

Low back pain; imaging studies; plain x-ray, magnetic resonance imaging (MRI); computed tomography (CT) scan

Denominator Description

Patients age 18 years as of January 1 of the measurement year to 50 years as of December 31 of the measurement year, with a Negative Diagnosis History, who had an outpatient or emergency department (ED) visit with a primary diagnosis of low back pain (see the related "Denominator Inclusions/Exclusions" field)

Numerator Description

An imaging study with a diagnosis of low back pain on the Index Episode Start Date (IESD) or in the 28 days following the IESD (see the related "Numerator Inclusions/Exclusions" field)

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A clinical practice guideline or other peer-reviewed synthesis of the clinical research evidence
  • A formal consensus procedure, involving experts in relevant clinical, methodological, public health and organizational sciences
  • One or more research studies published in a National Library of Medicine (NLM) indexed, peer-reviewed journal

Additional Information Supporting Need for the Measure

Unspecified

Extent of Measure Testing

All HEDIS measures undergo systematic assessment of face validity with review by measurement advisory panels, expert panels, a formal public comment process and approval by the National Committee for Quality Assurance's (NCQA) Committee on Performance Measurement and Board of Directors. Once NCQA establishes national benchmarks for accountable care organization (ACO) performance, all measures will undergo formal reliability testing of the performance measure score using beta-binomiol statistical analysis. Where applicable, measures also are assessed for construct validity using the Pearson correlation test.

Denominator Inclusions/Exclusions

Inclusions
Patients age 18 years as of January 1 of the measurement year to 50 years as of December 31 of the measurement year, with a Negative Diagnosis History, who had an outpatient visit (Outpatient Value Set), an observation visit (Observation Value Set), an emergency department (ED) visit (ED Value Set), or osteopathic manipulative treatment (Osteopathic Manipulative Treatment Value Set), with a principal diagnosis of low back pain (Low Back Pain Value Set), during the Intake Period

Note:

  • Intake Period: January 1 to December 3 of the measurement year. The Intake Period is used to identify the first outpatient or ED visit with a primary diagnosis of low back pain. If the patient had more than one visit, include only the first visit.
  • Negative Diagnosis History: A period of 180 days (6 months) prior to the Index Episode Start Date (IESD) when the patient had no visits with any diagnosis of low back pain.
  • IESD: The earliest date of service for any outpatient or ED visit during the Intake Period with a primary diagnosis of low back pain.

Refer to the original measure documentation for steps to identify the eligible population.

Exclusions
