PI 19 - Kidney function test result

Proportion of Indigenous regular clients with a selected chronic disease who have had a kidney function result (eGFR and ACR) within a specified level.

Description

Proportion of regular clients who are Indigenous aged 18 years and over, who are recorded as having one of the following:

Type 2 diabetes
Cardiovascular disease (CVD)
Type 2 diabetes and/or CVD

whose estimated glomerular filtration rate (eGFR) AND albumin/creatinine ratio (ACR) recorded within the previous 12 months were categorised as:

Normal risk
Low risk
Moderate risk
High risk

Table 1. eGFR & ACR risk categories
Risk level	Description
Normal risk	eGFR greater than or equal to 60 mL/min/1.73m² and: ACR less than 3.5 mg/mmol for females ACR less than 2.5 mg/mmol for males.
Low risk	eGFR greater than or equal to 45 mL/min/1.73m² and less than 60 mL/min/1.73m² and either: ACR less than 3.5 mg/mmol for females ACR less than 2.5 mg/mmol for males. OR eGFR greater than or equal to 60 mL/min/1.73m² and either: ACR greater than or equal to 3.5 mg/mmol and less than or equal to 35 mg/mmol for females ACR greater than or equal to 2.5 mg/mmol and less than or equal to 25 mg/mmol for males.
Moderate risk	eGFR greater than or equal to 45 mL/min/1.73m² and less than 60 mL/min/1.73m² and either: ACR greater than or equal to 3.5 mg/mmol and less than or equal to 35 mg/mmol for females ACR greater than or equal to 2.5 mg/mmol and less than or equal to 25 mg/mmol for males. OR eGFR greater than or equal to 30 mL/min/1.73m² and less than 45 mL/min/1.73m2 and either: ACR less than 35 mg/mmol for females ACR less than 25 mg/mmol for males
High risk	eGFR greater than or equal to 30 mL/min/1.73m² and either: ACR greater than 35ml/mmol for females ACR greater than 25mg/mmol for males mg/mmol OR eGFR less than 30 mL/min/1.73m² and : Any ACR result for both females and males

Notes

User may select between AIHW's definition of Regular Client (attended the OATSIH-funded primary health care service at least 3 times in 2 years), or Communicare's Current Patient status.
Patients must be recorded as Aboriginal or Torres Strait Islander or both.

Element	Description
Communicare reports	Report > National KPI > PI19 Kidney Function Results Patients Report > National KPI > PI19 Kidney Function Results
Numerator	ACR results are identified as belonging to a qualifier with the system code of `ACR`. Both laboratory and manually entered results are included. For more information, see System codes. eGFR results are identified as belonging to a qualifier with the system code of `GFE`. Both laboratory and manually entered results are included. GFR results of `>60` are included in the group `Greater than or equal to 60 but less than 90`.
Denominator	Regular, Indigenous patients aged 18 years and over at the end of the report period with Type II diabetes or CVD.
Disaggregation	Age 18–24 years 25–34 years 35–44 years 45–54 years 55–64 years 65 years and older Sex Male - calculation A Female - calculation B Chronic disease Type 2 diabetes Cardiovascular disease Either or both of the above
Additional data recording considerations	Where an eGFR result of `>60` has been returned by a lab these are reported as `Greater than or equal to 60 but less than 90`. Renal function risk result classifications differ between males and females. Type 2 diabetes – specifically excludes Type I diabetes, secondary diabetes, gestational diabetes mellitus (GDM), previous GDM, Impaired fasting glucose, and impaired glucose tolerance ACR – refers to an albumin/creatinine ratio Negative ACR and eGFR values are reported as not recorded
