ACEi or ARB Use in Diabetes Mellitus (Types 1 and 2) with CKD in the Military Health System

ACEi or ARB Use in Diabetes Mellitus (Types 1 and 2) with CKD in the Military Health System

Angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) use among Military Health System (MHS) beneficiaries with types 1 and 2 diabetes mellitus and chronic kidney disease (CKD) decreased from 69.7% to 63.6% (age-standardized) between 2016 and 2023. Use was generally higher during the period among adults aged over 60 years (crude) and males (age-standardized).

Data includes CKD stages 1–5. Estimates were standardized to the 2010 U.S. Census population for adults.

The Military Health System (MHS) provides comprehensive primary and specialty care for more than 9.6 million active-duty personnel and military retirees and their families worldwide. The MHS Data Repository (MDR) is the administrative claims database for all care received through MHS, including direct care received in military treatment facilities and purchased care received in civilian treatment facilities. The MDR does not capture health care delivery in combat zones or care received in the VHA system. All patients were in the TRICARE Prime managed care option. Data are from both the direct care (military facilities) and private care (private facilities through TRICARE coverage) systems.

De-identified patient data were obtained from the MHS data repository. Data contain both the estimated glomerular filtration rate (eGFR) definition of chronic kidney disease (CKD) and claims-based CKD defined by using ICD-9-CM and ICD-10-CM codes diagnosis codes with at least one inpatient or two outpatient CKD diagnoses. To be included in analyses, service members and their dependents had to have at least one inpatient or outpatient record during the fiscal year (October 1 to September 30). Data cells with 10 or fewer patients were suppressed.

Fiscal years 2016–2023 (October 1, 2015–September 30, 2023).

Numerator

MHS beneficiaries in the denominator population with filled ACEi or ARB prescription during each year.

Denominator

MHS beneficiaries aged ≥ 18 years with diagnosed type 1 diabetes or type 2 diabetes mellitus and CKD each year.

Exclusions

Adults with a diagnosis of dialysis or transplant and females with an ICD-10 code for pregnancy during the year were excluded from the denominator.

Definition of CKD and CKD Stages

CKD is defined as having one of the following: (1) one inpatient or two outpatient CKD ICD-10 codes, or (2) an average estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m² over the fiscal year, or (3) an average urine albumin-to-creatinine ratio ≥ 30 mg/g or average urine protein-to-creatinine ratio ≥ 0.15 g/g.

CKD stage 1 is an average eGFR ≥ 90 ml/min/1.73 m² who meet the criteria for either CKD ICD-10 codes or abnormal albuminuria/proteinuria.

CKD stage 2 is an average eGFR ≥ 60-89 ml/min/1.73 m² who meet the criteria for either CKD ICD-10 codes or abnormal albuminuria/proteinuria.

CKD stage 3 is an average eGFR = 30-59 ml/min/1.73 m².

CKD stage 4 is an average eGFR = 15-29 ml/min/1.73 m².

CKD stage 5 is an average eGFR < 15 ml/min/1.73 m².

Dialysis and Transplant

Beneficiaries with ≥1 inpatient or ≥2 outpatient encounters with ICD-10 codes for dialysis or transplant were excluded.

Definition of Diabetes

Type 1 and type 2 diabetes are determined using the Stanford algorithm (https://phekb.org/phenotype/1506), which uses one encounter with an ICD code for diabetes plus either the presence of prescribed hypoglycemic medications or the presence of abnormal chemistries (random outpatient glucose > 200 mg/dL or hemoglobin A1C ≥ 6.5%).

Age Standardization

Estimates were standardized to the 2010 U.S. Census population for adults: 18–39 years: 37.1%, 40–59 years: 38.1%, 60–69 years: 12.8%, and 70+ years: 12.0%.

Limitations of Indicator

Approximately 36% of adults with type 2 diabetes in the MHS each year do not have a recorded outpatient serum creatinine result, either due to no testing or testing done privately with inaccessible data. Consequently, the denominators would not include adults with undocumented eGFR < 60 mL/min/1.73 m² unless they also had ICD-10 codes for CKD or abnormal albuminuria or proteinuria. 

The percentage of adults in the denominator with unknown or unmeasured eGFR ranged from 15.5%–26.9%, with the higher numbers in later years mainly due to an increased proportion of beneficiaries seen in the private sector. 

The percentage of adults in the denominator with missing race declined from 18.1% to 11.1% from 2016 to 2023, while the percentage with unknown race declined from 11.0% to 5.0%. 

Analytical Considerations

Published studies define CKD using different serum creatinine criteria, such as single measurements, averages, or persistence over 90 days; comparisons must be made cautiously.
