Common tests & procedures
Fewer than 18% of CKD patients (235/1,312) were correctly diagnosed with CKD. The decisions by PCPs not to prescribe BP- or lipid-lowering agents for CKD patients only adhered to guideline recommendations in 51% and 46% of cases, respectively. Open in a separate window
What percentage of patients with chronic kidney disease are correctly diagnosed?
The risk of cardiovascular outcomes is greater than the risk of progression to end-stage kidney disease for most people with CKD. CKD also predisposes to acute kidney injury – a major cause of morbidity and mortality worldwide.
How does chronic kidney disease affect the risk of cardiovascular disease?
Optimal management of CKD includes cardiovascular risk reduction, treatment of albuminuria, avoidance of potential nephrotoxins, and adjustments to drug dosing. Patients also require monitoring for complications of CKD, such as hyperkalemia, metabolic acidosis, anemia, and other metabolic abnormalities.
What is the optimal management of chronic kidney disease (CKD)?
Fewer than 18% of CKD patients (235/1,312) were correctly diagnosed with CKD. The decisions by PCPs not to prescribe BP- or lipid-lowering agents for CKD patients only adhered to guideline recommendations in 51% and 46% of cases, respectively.
How accurate are PCP guidelines for diagnosing chronic kidney disease?
What patient specific factors most often contribute to chronic kidney disease?
Diabetes and high blood pressure, or hypertension, are responsible for two-thirds of chronic kidney disease cases. Diabetes: Diabetes occurs when your blood sugar remains too high.
How is chronic kidney disease diagnosed?
Chronic kidney disease (CKD) can be diagnosed with blood and urine tests. In many cases, CKD is only found when a routine blood or urine test you have for another problem shows that your kidneys may not be working normally.
How does the diagnosis stage 3 chronic kidney disease affect your choices?
In Stage 3 CKD, your kidneys have mild to moderate damage, and they are less able to filter waste and fluid out of your blood. This waste can build up in your body and begin to harm other areas, such as to cause high blood pressure, anemia and problems with your bones.
What is the main reason for chronic kidney disease diagnosis group of answer choices?
Diabetes and high blood pressure are the most common causes of chronic kidney disease (CKD).
What tests are used to diagnose kidney disease?
Tests for kidney diseaseBlood test: eGFR.Blood test: Serum creatinine test.Blood urea nitrogen (BUN) test.Urine test.Kidney ultrasound.Kidney biopsy.
What causes chronic kidney disease?
What causes CKD? The two most common causes of CKD are diabetes and high blood pressure. Diabetes means that your blood sugar is too high, which can damage your kidneys. High blood pressure means that the force of blood in your blood vessels is too strong, which can damage your blood vessels and lead to CKD.
What is the treatment for stage 3 chronic kidney disease?
The more impactful symptoms of kidney disease stage 3 are the health implications of your decreased kidney functioning such as high blood pressure, anemia, and bone disease. If your kidneys fail, you will either need to have dialysis or a kidney transplant. Dialysis is a treatment that will clean your blood.
What are the 5 stages of chronic kidney disease?
Five stages of chronic kidney diseaseStage 1 with normal or high GFR (GFR > 90 mL/min)Stage 2 Mild CKD (GFR = 60-89 mL/min)Stage 3A Moderate CKD (GFR = 45-59 mL/min)Stage 3B Moderate CKD (GFR = 30-44 mL/min)Stage 4 Severe CKD (GFR = 15-29 mL/min)Stage 5 End Stage CKD (GFR <15 mL/min)
How many stages are there in kidney disease?
There are five stages of chronic kidney disease. The mildest are stages 1 and 2. In these early stages of kidney disease, the kidneys are damaged and not working at full strength. At stage 3, about half of kidney function has been lost.
When is CKD formally diagnosed?
According to the KDIGO CKD guidelines (and the English National Institute for Health and Care Excellence (NICE) CKD guidelines), a patient is identified with CKD if abnormalities of kidney structure or function were present for a minimum of 3 months.

What is the leading cause of CKD and ESRD in both developed and developing countries?
Diabetes mellitus (DM) is the leading cause of CKD and ESRD in both developed and developing countries.3According to the registry of Turkish Society of Nephrology, diabetic patients constitute 37.3% of the hemodialysis population in Turkey.26According to the USRDS data, half of the new ESRD patients in the United States have diabetic nephropathy.27
How can we reduce the economic burden of kidney disease?
One way to reduce the economic burden of chronic kidney disease would be early intervention. In order to achieve this, we should be able to identify individuals with increased risk of renal disease. An individual's genetic and phenotypic make-up puts him/her at risk for kidney disease. Factors such as race, gender, age, and family history are highly important. For instance, being of African-American decent, older age, low birth weight and family history of kidney disease are considered to be strong risk factors for chronic kidney disease. Moreover, smoking, obesity, hypertension, and diabetes mellitus can also lead to kidney disease. An uncontrolled diabetic and/or hypertensive patient can easily and quickly progress to an end-stage kidney disease patient. Exposure to heavy metals, excessive alcohol consumption, smoking, and the use of analgesic medications also constitute risks. Experiencing acute kidney injury, a history of cardiovascular disease, hyperlipidemia, metabolic syndrome, hepatitis C virus, HIV infection, and malignancy are further risk factors. Determination of serum creatinine levels and urinalysis in patients with chronic kidney disease risk will usually be sufficient for initial screening.
What is the cause of low nephron numbers?
In the 1980s, Brenner and colleagues hypothesized that intrauterine growth restriction might cause a low nephron number, which could predispose to hypertension and renal disease (also known as the Barker hypothesis).13In support of this hypothesis, it has been shown that there is an increase in nephron numbers by 257,426 glomeruli per kg increase in birth weight.14Low nephron number leads to intraglomerular hypertension and hyperfiltration in the available nephrons and lower over-all GFR and higher urine albumin-to-creatinine ratio.15In a recent cohort study with a maximum follow-up of 38 years, low birth weight and intrauterine growth restriction were significantly associated with increased risk for ESRD among Norwegians.15
How high is the risk of ESRD in African Americans?
Several studies performed in the United States have confirmed an increased risk for the development of ESRD in African Americans compared with Caucasians.10Moreover, the risk of hypertensive ESRD is approximately fivefold higher in African Americans.11In a recent study, it was found that the lifetime risk of ESRD was 7.8% for 20 year old black women, 7.3% for black men, 1.8% for white women, and 2.5% for white men.3
What is the significance of acute kidney injury?
Researchers have recognized the importance of acute kidney injury (AKI) episodes in the development of CKD.25According to 2009 USRDS data, adults with a history of AKI during hospitalization had a 10-fold greater risk of developing ESRD in the next 12 months than those without AKI episode.25Even after a single episode of experimental AKI, histologic repair can be impaired and focal tubulointerstitial fibrosis may develop.25
What is CKD in health?
Chronic kidney disease (CKD) is a health problem, which could lead to end-stage renal disease (ESRD) and increased cardiovascular morbidity and mortality. According to the registries of different countries including the United States, CKD affects 10–16% of adults around the world.1Within the Turkish population the prevalence of CKD is 15.7%.2Identification of factors predisposing an individual to CKD is essential in terms of personal and community health, as some risk factors can be modified and can prevent or slow down progression to ESRD. This paper aims to review the risk factors, such as age, gender, race and ethnicity, family history, drug use, smoking, and socioeconomic status; and concurrent diseases, such as hypertension and diabetes which are traditionally or nontraditionally associated with CKD.3
What are the risk factors for ESRD?
One of the strongest yet modifiable risk factors for ESRD in the twenty-first century is obesity .16Glomerular hypertrophy and hyperfiltration may accelerate kidney injury by increasing capillary wall tension of the glomeruli and decreasing podocyte density.16
Why is chronic kidney disease bad?
Chronic kidney disease may be caused by diabetes, high blood pressure and other disorders. Early detection and treatment can often keep chronic kidney disease from getting worse. When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life.
What are the high risk groups for kidney failure?
High risk groups include those with diabetes, hypertension and family history of kidney failure.

Most people may not have any severe symptoms until their kidney disease is advanced. However, you may notice that you:
How to tell how much kidney function you have?
Calculate your Glomerular Filtration Rate (GFR), which is the best way to tell how much kidney function you have. You do not need to have another test to know your GFR. Your doctor can calculate it from your blood creatinine, your age, race, gender and other factors. Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment.
What is CKD in medical terms?
Chronic kidney disease (CKD) is a condition characterized by a gradual loss of kidney function over time. To read more about kidney function, see How Your Kidneys Work. CKD is also known as chronic renal disease.
What causes kidney disease?
The two main causes of chronic kidney disease are diabetes and high blood pressure, which are responsible for up to two-thirds of the cases. Diabetes happens when your blood sugar is too high, causing damage to many organs in your body, including the kidneys and heart, as well as blood vessels, nerves and eyes.
How many people in the US have CKD?
More than 1 in 7, that is 15% of US adults or 37 million people, are estimated to have CKD. *. As many as 9 in 10 adults with CKD do not know they have CKD. About 2 in 5 adults with severe CKD do not know they have CKD.

Why is understanding CKD important?
Understanding the definition and staging of CKD is crucial to correctly identify people with the condition in clinical practice. Such information is also a key to appropriately advise patients about their kidney health and stratify their future risk.
Why is it important to communicate with patients with CKD?
In early CKD, comorbidities may be of greater importance to patients with CKD, although this may change if CKD progresses. 91 Clinicians in primary care therefore have an important overseeing and coordination role to provide better integration of care for people with CKD. 92 Linked to this is the importance of good communication with patients who have CKD. This applies at mild-to-moderate stages in order to discuss risk stratification and inform self-management efforts including smoking cessation and weight loss (if overweight or obese) and the potential need for pharmacological intervention. It is also vital in more advanced CKD where informed decisions are needed with regard to dialysis and transplantation and in decisions to opt for palliative treatment. 93 In this context, the evidence that health literacy may be poor in a high proportion of people with CKD is of concern. 94 The response to this, however, may not just be to simplify messages for patients but to encourage education programmes and patient support groups in order to empower patients and increase self-efficacy.
How often should I monitor ACR?
Recommended frequency of ACR monitoring also varies across different guidelines. Johnson 49 provided a useful summary of the variation, with several bodies not specifying a recommended testing frequency (the KDOQI, Caring for Australasians with Renal Insufficiency [CARI], Scottish Intercollegiate Guidelines Network [SIGN], and Canadian Society of Nephrology [CSN]), while others recommend annually or “at least annually” (NICE, Royal Australian College of General Practitioners [RACGP], and European Renal Best Practice Guidelines [ERBP]). KDIGO guidelines recognize the areas of uncertainty in this area: “We recommend further research to more accurately define the frequency with which GFR and albuminuria measurements should be performed based on their ability to inform strategies which prevent adverse outcomes (eg, progression of kidney disease and death)”. 6 This therefore remains an area for which further evidence is needed, and, in the meantime, frequency of monitoring should be guided by the clinical situation and degree of risk as stratified using the KDIGO framework. For the majority of people with CKD in primary care (who are likely to have stages G1–G3 and A1), annual ACR testing is likely to be sufficient to quantify the degree of any albuminuria and detect change. 5 This is best conducted on an early morning urine specimen, particularly for quantification. 5
How is CKD diagnosed?
It is identified and defined by the presence of an abnormality of kidney structure or function (or both) present for at least 3 months. 5, 6 It is classified by the degree of renal dysfunction, as measured by the estimated glomerular filtration rate ( [eGFR] derived from serum creatinine using standard estimating equations) and by the presence or absence of structural kidney abnormality or by other evidence of chronic kidney damage, particularly albuminuria. 6 The Kidney Disease Improving Global Outcomes (KDIGO) organization has summarized the stages of CKD using a “traffic light” staging system that incorporates both creatinine-based eGFR and albuminuria ( Figure 1 ). 6 This classification gives five levels of dysfunction defined by eGFR (G1–G5) and three by albuminuria (A1–A3). As such, a person with normal or mildly decreased eGFR (G1 or G2) and little or no albuminuria (A1) is considered at low risk, whereas someone with eGFR < 60 mL/min/1.73 m 2 and a moderate degree of albuminuria is at greater risk. This inclusion of albuminuria (usually measured by urinary albumin-to-creatinine ratio [ACR]) recognizes the independent prognostic importance of both eGFR and albuminuria to a variety of renal and nonrenal outcomes, including mortality, progression to end-stage kidney disease, cardiovascular disease, and AKI. 7 – 14 Key to the definition of CKD is the need to assess these markers of renal function over time in order to confirm chronicity.
What is the importance of BP in CKD?
Managing hypertension is a key strength of primary care and controlling BP arguably the most important intervention in reducing both progression and cardiovascular risk in people with CKD. A very high proportion of the population of people with CKD have hypertension. In a large database study in Canada (n=530,771), ~47% of people with all stages CKD had hypertension. 3 In the US Kidney Early Evaluation Program (KEEP) database, hypertension prevalence was >80% among people with eGFR <60 mL/min/1.73 m 2 or albuminuria ≥3 mg/mmol, and in a UK cohort study of 1,741 people with CKD stage 3, the prevalence was 88%. 79, 80
What is CKD in primary care?
Chronic kidney disease (CKD) is a common condition that refers to a long-term loss of kidney function. It tends to be diagnosed in the presence of other comorbidities (particularly hypertension, diabetes, and cardiovascular disease), isolated CKD is the exception rather than the rule, and CKD is associated with socioeconomic deprivation. 1 – 3 Effective identification and management are necessary in order to prevent CKD progression and cardiovascular events, reduce the risks associated with acute kidney injury (AKI), and improve patient safety and medicines management. Historically, it was considered that managing patients with CKD is the responsibility of nephrologists in secondary care settings, but improved understanding of the nature and implications of early stages of the condition mean that primary care clinicians have an essential role to play. 4 For those working in primary care, an understanding of the condition is required in order to identify people with CKD, undertake appropriate risk stratification, communicate the diagnosis to patients, and work with them toward optimal management and risk reduction. This review is not a clinical guideline, rather it draws upon existing national and international guidelines to summarize the importance of CKD and provide an overview of key aspects in its management in primary care.
Why is primary care important?
Primary care plays an important role in the monitoring and management of CKD, particularly in efforts to reduce the risk of cardiovascular disease and other complications. Only a small proportion of people with mild or moderate CKD will progress to end-stage disease. In a population-based study in Norway (the HUNT II study), for example, of 3,069 people with CKD followed for median 8 years, only 38 (1%) progressed to end-stage disease. 44 Therefore, the main purpose of monitoring in people with CKD is to undertake risk stratification incorporating objective measures alongside clinical judgment in discussion with the patient and to regularly review this risk, not only to identify this small proportion of people at risk of disease progression but also to identify those at risk of other complications, particularly cardiovascular disease and AKI.
What are the complications of CKD?
Complications include, but are not limited to, cardiovascular disease; anemia; malnutrition; mineral and bone disorders; depression and reduced functional status.
What is the management of CKD?
Management of CKD involves an interdisciplinary approach. Monitoring trends in urine albumin-to-creatinine ratios (UACR) and estimated glomerular filtration rates (eGFR) may be used to assess response to interventions. Medical interventions that may help slow progression include control of blood pressure, use of medications that block the renin-angiotensin-aldosterone system (RAAS) to lower urine albumin; and glucose control in those with diabetes. Interventions may include nutrition therapy, lifestyle modification, and self-management education.
Why is it important to know your kidneys?
Knowledge of kidney function is important for dosage of medications that are excreted by the kidneys. Food and Drug Administration (FDA)-approved drug-labeling guides provide adjustments of drug dosages for patients with impaired kidney function.
What is chronic kidney disease?
Chronic kidney disease (CKD) means that your kidneys are diseased or damaged in some way, or are ageing. As a result, your kidneys may not work as well as they used to. A range of conditions can cause chronic kidney disease (see later).
Why do you need to treat kidney disease?
You may need treatments to reduce your risk of progressing to more severe chronic kidney disease. You will probably also need other treatments to reduce your risk of any other problems, particularly cardiovascular diseases (CVDs - see below).
What is the relationship between increased protein in urine and decreased eGFR?
Increased protein in the urine and decreased eGFR are both associated with an increased risk of progressive chronic kidney disease.
What does it mean when your kidneys are not working?
Chronic kidney disease means that your kidneys are not working as well as they once did. Various conditions can cause chronic kidney disease. Severity can vary but most cases are mild or moderate, occur in older people, do not cause symptoms and tend to become worse gradually over months or years.
How is eGFR calculated?
The eGFR is calculated from your age, sex and blood creatinine level. An adjustment to the calculation is needed for people with African-Caribbean origin. See the separate leaflets called Routine Kidney Function Blood Test and Estimated Glomerular Filtration Rate (eGFR).
What does CKD mean?
Chronic Kidney Disease. Chronic kidney disease (CKD) means that your kidneys are not working as well as they once did . Various conditions can cause CKD. Severity can vary but most cases are mild or moderate, occur in older people, do not cause symptoms and tend to become worse gradually over months or years.
How is creatinine cleared from the blood?
Creatinine is normally cleared from the blood by the kidneys. If your kidneys are not working so well and the glomeruli are not filtering as much blood as normal, the level of creatinine in the blood goes up. The eGFR is calculated from your age, sex and blood creatinine level.
