简要总结
Chronic Kidney Disease (CKD) is a worldwide major public health problem that is associated with an increased incidence of kidney failure and cardiovascular events, that lead a high burden for affected patients and high costs for society. Symptoms of CKD occur late, when kidney function drops to below 30%. At that time preventive measures will have only limited efficacy. Protein excretion in urine has increasingly been recognized as early marker of CKD, and is often associated with high blood pressure, diabetes, and/or high cholesterol levels. These are all important risk factors for progression of kidney and cardiovascular disease. Population screening for urinary protein loss could detect a considerable number of subjects with yet unknown risk factors for progressive kidney and cardiovascular disease who can benefit of early intervention. However, there is no validated method for population screening yet. The aim is to to develop a home based population screening for elevated urinary protein loss. Two screening methods will be investigated, and yield and cost-effectiveness of these screening methods will be evaluated
详细描述
Chronic kidney disease (CKD) is a worldwide major public health problem that is associated with an increased incidence of kidney failure and cardiovascular disease (CVD). To tackle this burden, screening for CKD among the general population could be beneficial to allow early detection and treatment. In the last decades, elevated albuminuria has increasingly been recognized as an early marker of generalized vascular endothelial damage, that predicts CKD and CVD progression.
It has been estimated that approximately 6% of the general population has elevated albuminuria, and that the majority of these subjects are not known yet with this abnormality. Among these subjects, many have hypertension, hyperlipidemia, diabetes and/or impaired kidney function, that often is also not known yet. Early detection of elevated albuminuria may be important because it gives the opportunity to invite subjects that test positive for further screening for CKD and CVD risk factors. Thus these risk factors for CKD and CVD progression could be treated in an early stage.
Population screening for albuminuria could be justified according to the WHO criteria of Wilson and Jungner , because CKD has important consequences for subjects, the course of the disease is initially symptomless, and there are treatment methods available. However, implementation research to validate screening the general population for albuminuria and related health consequences is lacking, as are cost-effectiveness studies.
In the current study the aim is to develop a home-based screening technique for detecting elevated albuminuria. Two screening methods will be investigated, and yield and cost-effectiveness of these screening methods will be evaluated

研究组 & 干预措施
Group A
Group A will receive an invitation for home based albuminuria screening using a more conventional urine collection device (known as "Peespot Test").
干预措施: Approach A (PeeSpot urine collection device). (Diagnostic Test)
Group B
Group B will receive an invitation for home based albuminuria screening using an app (internet application) and an ACR dipstick test (known as "ACR| EU Test").
干预措施: Approach B (ACR | EU Test kit). (Diagnostic Test)
结局指标
主要结局
Participation rate of the screening (i.e. home-based screening, elaborate screening and overall screening program)
时间窗: Screening period of 6 months.
The participation rate is defined as the number of persons completing the albuminuria screening (i.e. returning the first PeeSpot urine device or scanned the first ACR \| EU urine test strip with use of the app, and in case of an ACR \>30 mg/g in this initial test, also completing the a confirmatory albuminuria screening tests), elaborate screening and overall screening program relative to the invited number of individuals.
The yield of albuminuria screening.
时间窗: Screening period of 6 months.
These are twofold. First, the yield of the home-based screening is defined as the number of persons who test positive for albuminuria (at least 2 tests positive) relative to the number of persons participating in the corresponding arm (=per-protocol analysis) and of all invited persons in the corresponding arm (intention-to-screen analysis). Second, the yield of the elaborate screening is defined as the number of subjects with increased albuminuria (defined as ACR \>30 mg/g) with newly diagnosed and/or poorly controlled CVD and CKD risk factors. These risk factors, which will be assessed during the elaborate screening, include hypertension, diabetes mellitus, hyperlipidemia, impaired kidney function.
Cost-effectiveness of the screening.
时间窗: 6 months follow-up after screening period.
Incremental cost-effectiveness ratio (ICER) in euro per QALY gained for the two screening methods;
次要结局
