Point-of-Care Testing in Outpatient Diabetes Care

September 4, 2025 updated by: Jun-Sing Wang, MD, PhD, Taichung Veterans General Hospital

Evaluation of a Fast Point-of-care Platform for Diabetes Care at Out-patient Clinics

Using a point-of-care (POC) platform, the investigators will investigate the effects of POC testing for glycated hemoglobin (HbA1c) and cystatin C at out-patient clinics on long-term diabetes outcomes.

Study Overview

Status

Active, not recruiting

Conditions

Intervention / Treatment

Detailed Description

Laboratory testing for HbA1c and cystatin C is time-consuming, and healthcare providers often do not have update results when they evaluate outpatients with diabetes. A POC testing platform may help address this issue, and the investigators aim to examine its effects on diabetes outcomes.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Outpatients with diabetes who provide consent to POC testing
Intervention: POC testing for HbA1c and cystatin C. Observational follow up: data on fasting glucose, HbA1c, serum creatinine, urine albumin to creatinine ratio (UACR), lipids profile, ...etc.
POC testing for HbA1c and cystatin C
No Intervention: Outpatients with diabetes who decline to POC testing, but consent to observational follow up
This group will serve as the controls. Follow up data on fasting glucose, HbA1c, serum creatinine, urine albumin to creatinine ratio (UACR), lipids profile, ...etc.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes from baseline to the end of study in eGFR
Time Frame: Observational follow up period of 3 years
Estimated glomerular filtration rate (eGFR) will be determined using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation (Levey AS, et al. Ann Intern Med. 2009; 150: 604-12).
Observational follow up period of 3 years

Secondary Outcome Measures

Outcome Measure
Time Frame
Changes from baseline to the end of study in UACR
Time Frame: Observational follow up period of 3 years
Observational follow up period of 3 years

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incident chronic kidney disease
Time Frame: Observational follow up period of 3 years
incident chronic kidney disease is defined as an eGFR <60 ml/min/1.73 m2 of at least 3 months duration.
Observational follow up period of 3 years
