Days at Home for Patients with Complex, Chronic Conditions

CBE ID
4555
Endorsement Status
E&M Committee Rationale/Justification

After the endorsement meeting, the developer of CBE #4555 submitted an appeal due to the following rationales:

  1. Procedural error in the endorsement process.
  2. Misapplication of measure evaluation criteria, specifically risk adjustment.

The appellant posited the:

  1. Discussion focused on out-of-scope topics (broader population beyond Medicare FFS and ACO-REACH). Insufficient time for comprehensive discussion. Dominance of a few voices, limiting inclusive discussion.
  2. Measure meets risk adjustment criteria. Variables in the risk model influence the outcome and are present at the start of care. Model excludes unjustified factors associated with care inequities. Measure adjusts for dual eligibility, accounting for social risk factors. ACO REACH Model provides resources for coordinated care, supporting the measure's intent.

The Appeals Committee voted to uphold the appeal based on both rationales above. Therefore, the measures’ s endorsement decision was overturned to Endorsed with Conditions. When the measure returns for maintenance (5 years), the measure developer should have: 

  • Explored differences in scores for rural and urban settings and/or explore whether adjusting on these variables is needed.
  • Explored the impact of variation in attribution based on utilization (in the denominator).

1.6 Measure Description

This is an ACO-level measure of days at home or in community settings (that is, not in acute care such as inpatient hospital or emergent care settings or post-acute skilled nursing) among adult Medicare Fee-for-Service (FFS) beneficiaries with complex, chronic conditions who are attributed to ACOs participating in the ACO REACH model. The measure includes risk adjustment for differences in patient mix across ACOs, with an additional adjustment based on patients’ risk of death. A policy-based nursing home adjustment that accounts for patients’ risk of transitioning to a long-term nursing home is also applied to incentivize community-based care. The performance period is one calendar year.

1.10 Measure Rationale

The goal of this outcome measure is to reduce unnecessary or excessive hospitalizations for Medicare patients with complex chronic conditions, thus increasing their “days at home.” Through reporting this outcome measure, ACOs will be able to compare their performance in relation to others and use the results to identify the root causes of excess acute care utilization, including insufficient or low-quality outpatient care. Improvements in this outcome mean that patients will spend fewer days in acute care settings, and more days at home or in the community, which often reflects patient preferences as well as cost savings to patients and providers. 

1.20 Types of Data Sources
1.25 Data Source Details

The measure uses CMS beneficiary enrollment and claims data for a given year accessed via the CMS Integrated Data Repository (IDR) and Chronic Conditions Data Warehouse Virtual Research Data Center (VRDC):

  • Medicare inpatient claims
  • Medicare outpatient claims
  • Medicare SNF claims
  • Medicare beneficiary enrollment data 

The ACO-beneficiary alignment/attribution file is determined prospectively based on the requirements of the program; for testing, we used the 2018 Shared Savings Program ACO attribution file used by that program for its other claims-based measures and the 2022 ACO REACH alignment file furnished by CMS.
