Measure Steward Centers for Medicare & Medicaid Services (CMS)
Description

The measure assesses the number of inpatient hospitalizations for patients age 18 and older who have an acute kidney injury (AKI) stage 2 or greater that occurred during the encounter. AKI stage 2 or greater is defined as a substantial increase in serum creatinine value, or by the...

Risk Adjustment

Sex and Age

First vital signs since the encounter start:

- Heart Rate: {Beats}/min

- Respiratory Rate: {Breaths}/min

- Systolic Blood Pressure: mm[Hg]

- Temperature: Cel [degF]

The estimated glomerular filtration rate (eGFR) is calculated using the index serum creatinine, patient sex, and...

Rationale

This measure focuses on stage 2 or greater AKI as an outcome in the hospital inpatient setting. The incidence of AKI in general hospitalized patients is 10–20%, and among critically ill patients, the incidence of AKI has been reported as high as 45–50%; in cardiac surgery patients it...

Clinical Recommendation Statement

Serum creatinine is an accepted proxy for AKI (Ostermann et al., 2020; KDIGO, 2012). It is cited by many guidelines for defining and monitoring AKI (Lameire et al., 2021; Ostermann et al., 2020; Lopes & Jorge, 2013; KDIGO, 2012). eGFR equations that incorporate creatinine and cystatin C...

Definition

Inpatient hospitalizations: Includes time in the emergency department and observation when the transition between these encounters (if they exist) and the inpatient encounter are within an hour or less of each other.

The numerator harm, AKI stage 2 or greater, is defined as an increase in...

Guidance

A patient characteristic of male or female sex is required as part of the initial population criteria, as sex is crucial to this measure. For example:

- The eGFR estimating equation that is used to identify AKI is sex-specific; and

- The reference ranges for the serum creatinine value are...

Initial Population

Inpatient hospitalizations that end during the measurement period for patients 18 years of age or older without an obstetrical or pregnancy related condition, with a length of stay of 48 hours or longer, and who had at least one serum creatinine value after 48 hours from the start of the...

Equals Initial Population

Denominator Exclusions

Inpatient hospitalizations for patients with an increase in serum creatinine value of at least 0.3 mg/dL between the index serum creatinine and a subsequent serum creatinine taken within 48 hours of the encounter start.

Inpatient hospitalizations for patients with the index eGFR value of...

Numerator

Inpatient hospitalizations for patients who develop AKI stage 2 or greater during the encounter, as evidenced by:

A subsequent increase in serum creatinine value at least 2 times higher than the lowest serum creatinine value, and the increased value is greater than the highest...
