Defining Attributes
Definition
The measure assesses the number of inpatient hospitalisations for patients age 18 and older who have an acute kidney injury (stage 2 or greater) that occurred during the encounter.
Numerator
Inpatient hospitalisations for patients who develop AKI (stage 2 or greater) during the encounter, as evidenced by: (1) 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 sex-specific normal value for serum creatinine, OR (2) Kidney dialysis (CRRT, haemodialysis or peritoneal dialysis) initiated more than 48 hours after the start of the encounter. Evidence of a 2 times increase in serum creatinine is not required.
Denominator
Inpatient hospitalisations 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 hospitalisation.
Exclusions
• Inpatient hospitalisations 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 hospitalisations for patients with the index eGFR value of <60 mL/min within 48 hours of the encounter start. Inpatient hospitalisations for patients who have less than two serum creatinine results within the first 48 hours of the encounter start. • Inpatient hospitalisations for patients who have kidney dialysis (CRRT, haemodialysis or peritoneal dialysis) initiated 48 hours or less after the encounter start, and who do not have evidence of a 2 times increase in serum creatinine. • Inpatient hospitalisations for patients with at least one specified diagnosis present on admission or procedure that starts during the encounter that puts them at extremely high risk for AKI.
