Why is body composition analysis an
effective tool for dialysis programs?
Disclaimer: InBody devices should be used as an adjunct tool for clinical decision making and are not intended to diagnose or treat any diseases.
InBody devices take the guesswork out of dialysis treatments to help identify the most effective treatment options for the patient and obtain the ideal goal weight. In 60 seconds, professionals can use the InBody to:
- Obtain objective fluid measures to guide goal weight management
- Assess muscle and fat mass to make nutritional changes
- Evaluate segmental fluid imbalances to identify circulation issues
Importance of Fluid Balance
“Overhydration as assessed by ECW/TBW is prevalent in adult PD patients, and is associated with loss of residual renal function, inflammation, malnutrition and hypertension.”
Fan et al., 2012
Benefits of Phase Angle
“BIA is an attractive method because it is safe, easy to use, noninvasive, and relatively low cost. BIA-derived parameters have therefore been investigated as novel nutritional markers, especially in patients with ESRD who are receiving maintenance hemodialysis.”
Shin et al, 2017
Benefits of BIA with Goal Weight
“MF-BIA was superior…in the evaluation of body water distribution in end-stage renal disease and other clinical disorders of fluid volume and/or distribution and validation for assessment of body water in HD patients.”
Lee et al., 2001
Balance muscle and fat development per individual needs.
Dialysis vintage can disrupt lifestyle habits including diet and exercise, leading to malnutrition and muscle loss. Identifying changes in body composition allows dietitians and nutritionists to adjust nutrition plans and educate patients on importance of muscle and fat balance.
Restrictions to normal food intake and exercise can lead to malnutrition changes to body composition that can complicate the setting of appropriate dry weights. The InBody test tracks changes in body composition so dietitians and nutritionists can educate patients on dietary and exercise needs to promote muscle and fat maintenance. Understanding changes specific to each patient allows professionals to develop specific dietary recommendations based on individual needs.
Increase success of dialysis treatment and long-term outcomes
Doctors rely on indirect measures of fluid retention to determine how much fluid to remove or when to stop dialysis treatments, often leading to intradialytic complications. Direct fluid measures increase the precision with dialysis treatments and the establishment of goal weight for patients.
By understanding changes in body composition and the accumulation of fluids during the intradialytic period, physicians can determine how much water to remove and achieve an appropriate goal weight. Setting goal weights based on objective measures of body composition and fluid levels, physicians can avoid intradialytic complications such as hypo- or hypertensive episodes, increasing the success of dialysis treatments. Relieving these symptoms in patients leads to better long-term outcomes and attendance of appointments.
Segmental ECW/TBW Water Analysis
Avoid intradialytic complications from fluid accumulation
Intradialytic weight gain can be masked by the loss of muscle and fat mass. Professionals rely on the indirect practice of pitting edema to identify changes in fluid levels. Objective measures of body water help identify water retention as a form of weight change independent of changes in muscle or fat mass.
Nephrologists can use Segmental ECW/TBW Analysis to distinguish fluid accumulation from muscle and fat composition, allowing for more accurate tracking of fluid overload independent of nutritional status. This will allow physicians to set proper goal weights, confirm fluid volumes post-dialysis, and make more appropriate adjustments of patient goal weights long-term.
Why do nephrologists trust InBody?
All InBody professional body composition analyzers rely on four pillars of technology to deliver quick, accurate and precise results. These pillars allow you to trust that the results reflect your patients’ true health from the inside out.
Direct Segmental Measurement (DSM)
InBody Direct Segmental Bioelectrical Impedance Analysis (DSM-BIA) provides water measurements along with muscle mass and fat mass readings in each segment of the body: right arm, left arm, left leg, right leg and trunk. By measuring each segment of the body separately, the InBody is able to provide an in-depth analysis of a patient’s fluid balance for each region. These outputs include intracellular and extracellular water and ECW/TBW ratio. Objective measures of intracellular and extracellular water can identify fluid imbalances in a certain limb, while Segmental ECW/TBW can track circulation problems, disease progression and treatment efficacy.
InBody devices use multiple frequencies to measure body water more accurately than commonly used methods like pitting edema scores. These high and low frequencies are able to measure both intra- and extracellular water, producing more precise measurements of body water compartments. Having an accurate measure of the different water compartments can indicate fluid imbalances or water retention stemming from kidney dysfunction and can be used to monitor changes in fluid balance following dialysis treatment.
8 Point Tactile Electrodes
InBody devices use 8-Point Tactile Electrodes to ensure that measurements always start in the same place, test after test. This technology creates precise and reproducible results, ensuring the results professionals are seeing are genuine changes happening to their patient and are not due to error.
No Empirical Estimations
InBody devices do not rely on empirical data or pre-loaded data. Age, gender and ethnicity does not change an individual’s results, an important factor for nephrology professionals as renal dysfunction affects each patient differently. By not relying on pre-loaded data, nephrology professionals know that the data they are obtaining on their patient is based on that patient alone. Therefore, any changes that are happening to a patient reflects a genuine change in their body composition and fluid levels.
