2020 MIPS Measure #478: Functional Status Change for Patients with Neck Impairments

Quality ID 478
High Priority Measure Yes
Specifications Registry
Measure Type Outcome
Specialty Chiropractic Medicine Orthopedic Surgery Physical Therapy/Occupational Therapy

Measure Description

This is a patient-reported outcome performance measure (PRO-PM) consisting of a patient-reported outcome measure (PROM) of risk-adjusted change in functional status (FS) for patients aged 14+ with neck impairments. The change in FS is assessed using the Neck FS PROM.* The measure is risk-adjusted to patient characteristics known to be associated with FS outcomes. It is used as a performance measure at the patient, individual clinician, and clinic levels to assess quality.

*The Neck FS PROM is an item-response theory-based computer adaptive test (CAT). In addition to the CAT version, which provides for reduced patient response burden, it is available as a 10-item short form (static/paper-pencil).

 

Instructions

This outcome measure is to be submitted once per Treatment Episode for all patients with a functional deficit related to the neck. This is an outcome measure, and its calculation requires submitting of the patient’s FS PROM score, as a minimum, at the start (Initial Evaluation or Intake) and again at the conclusion (Discharge) of a Treatment Episode. The Initial Evaluation score is recorded during the first treatment encounter, and the Discharge score is recorded at or near the conclusion of the final treatment encounter. It is anticipated that Merit-based Incentive Payment System (MIPS) eligible clinicians providing treatment for functional neck deficits will submit this measure.

Measure Submission Type:

Measure data may be submitted by individual MIPS eligible clinicians, groups, or third party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality-data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.

 

Denominator

Patients aged 14+ who initiated rehabilitation therapy, chiropractic, or medical episodes of care for neck impairments including but not limited to cervical (neck) pain, radiculopathy, strain, sprain, stenosis, myelopathy, spondylosis or disc disorders

Denominator Criteria (Eligible Cases):

Patients 14 years and older

AND

Patient encounter during the performance period identifying evaluation (CPT or M-code): 97161, 97162, 97163, 97165, 97166, 97167, 99201, 99202, 99203, 99204, 99205, 99212, 99213, 99214, 99215, 98940, 98941, 98942, 98943 or M1143

 

Numerator

The proportion of a provider’s (clinic’s or clinician’s) patient care episodes that met or exceeded the risk-adjusted predicted Residual Change Score

Definition:

The Residual Change Score is defined as the difference between the Actual and Predicted Change Scores where.

  • The Actual Score is the patient’s Functional Status (FS) Score,
  • The Actual Change Score is the change in the patient’s FS score from Admission to Discharge, and
  • The Predicted Change Score is the risk-adjusted prediction of FS change

Calculating the Residual Change Score, Example:

Actual Score at Admission = 45
Actual Score at Discharge = 60
Actual Change Score (Discharge minus Admission) = +15
Predicted Change Score = +10
Residual (Actual Change minus Predicted) = +5

 

NUMERATOR NOTE: Performance may be calculated on 3 levels as follows:

  1. Patient Level: For the individual patient episode, the patient’s Actual FS scores relative to the risk-adjusted predicted. This level should be used for optimizing care as described below.*
  2. Clinician Level: The average of the Residuals for patient care episodes managed by a clinician (individual provider) over a 12 month time period.
  3. Clinic Level: The average of the Residuals for patient care episodes managed by a group of clinicians within a clinic over a 12 month time period.

* A provider’s (clinician’s or clinic’s) performance must be assessed based on an average all of the provider’s patient episodes. On the level of the individual patient, variation is expected. When an individual episode does not result in meeting or exceeding the performance standard, the functional data should be useful to the provider in optimizing the balance of effectiveness/efficiency for that particular care episode. For example, if patient-perceived function is not improving, or has plateaued in progress, that data may be a component of provider-patient communication and care decision-making such as the following examples:

  1. Does the provider understand the patient’s perception of his/her current level of function?
  2. Should the treatment plan be modified?
  3. Should the patient be discharged sooner than later?
  4. Should the patient be referred to a different care provider

 

Numerator Options:

Performance Met: The Residual Change Score is equal to or greater than 0 (G2152)

OR

Denominator Exception: Patient refused to participate at admission and/or discharge; patient unable to complete the Neck FS PROM at admission or discharge due to cognitive deficit, visual deficit, motor deficit, language barrier, or low reading level, and a suitable proxy/recorder is not available; patient self-discharged early; medical reason (G2166)

OR

Performance Not Met: The Residual Change Score is less than 0 (G2167)

 

Rationale

The findings by Wang and colleagues supported the uni-dimensionality and local independence of responses to the Neck FS PROM CAT. The items were found to have negligible differential item functioning and no ceiling or floor effects. The CAT-based measure yielded precision equal to a fixed measure that included all items. N=439, age 48.4 +/- 13.8, 59% female (Wang et al. 2015).

The primary sample in the study by Deutscher et al. included 250,741 patients, ages 14-89, who completed the Neck FS PROM CAT at admission (age/SD=54/16; 65% women). Of these, 169,039 patients completed the Neck FS CAT at discharge, resulting in a completion rate of 67%. The scale-level reliability of the Neck FS CAT was 0.91. Standard Errors of Measurement (SEMs) were stable across the measurement continuum ranging from 3.7 to 3.9 points (range = 0 to 100), which corresponds to 6.1 to 6.4 points at the 90% confidence interval (CI). Minimal Detectable Improvement (MDI) at the 90% CI ranged between 6.6 to 7.0 points. A half standard deviation of baseline scores was 6.2 points. Minimal clinically important improvement (MCII) estimates ranged from 15 to 4 points from 1st to 4th quartile of baseline Neck FS CAT scores, respectively. Thus, greater change was needed to achieve MCII for patients with lower baseline functional status. The majority of patients (61%) demonstrated functional staging change during treatment (Deutscher et al. 2018).


Clinical Recommendation Statements

PROMs are increasingly advocated as necessary components of an overall strategy to improve healthcare (Black 2013; Griggs et al. 2017) and are advocated for use in clinical decision making in clinical practice guidelines pertaining to neck impairments (Blanpied et al. 2017; Bier et al. 2018; Childs et al. 2008; Baisden et al. 2010; Bono et al. 2011). Placing risk-adjusted Neck FS PROM data directly into the hands of the provider embodies the definition of patientcentered healthcare and is consistent with National Quality Forum’s vision to achieve performance improvement and accountability through patient-reported outcomes (National Quality Forum 2013). This approach improves quality of care by promoting improved communication between provider and patient and enhancing the provider’s understanding of the patient’s perception of functional status. The Neck FS PROM and PRO-PM results can be shared with the patient to further promote patient engagement.
