Malnutrition is prevalent in sufferers on dialysis and is related to morbidity and mortality. Dietary standing may be assessed by a wide range of biochemical and bodily parameters or dietary evaluation scores. Most of those strategies are costly or cumbersome to make use of and should not appropriate for routine repetitive follow-up in dialysis sufferers. The Mini Dietary Evaluation (MNA) has a brief kind screening set (MNA-SF), which might be appropriate as a screening instrument, however has not been validated but in dialysis sufferers. We aimed to evaluate whether or not the MNA is an acceptable instrument for figuring out dietary issues in dialysis sufferers.


MNA, routine biochemistry, bodily parameters, comorbidities have been assessed in cross-sectional multicentric cohorts of hemodialysis and peritoneal dialysis sufferers with a longitudinal observe up of two years for mortality.


On this cohort of 216 sufferers, mortality was 27.3% at a observe up of 750±350 days. The imply MNA-SF rating was 9.9±1.8, with 30.1%, 59.3% and 10.6% of sufferers categorized as having regular dietary standing, in danger for malnutrition and malnourished, respectively. The screening rating was related to mortality (HR 0.86, 95% CI 0.75–0.98 per level). With regular diet as reference, adjusted mortality was 2.50 (95% CI 1.16–5.37) and three.89 (95% CI 1.48–10.13) for sufferers in danger for malnutrition and with malnutrition, respectively. After recalibrating the MNA full rating for the specificity of a few of its domains for dialysis sufferers, the MNA-SF had a great sensitivity and specificity for not being properly nourished (0.95 and 0.63 respectively) within the full rating, and a excessive unfavourable predictive worth (0.91).


The MNA-SF is independently related to 2 12 months mortality in dialysis sufferers. It has a excessive unfavourable predictive worth for excluding being in danger or having malnutrition within the full rating. Due to this fact, it may be advocated as a screening instrument for dietary standing in dialysis sufferers.


Malnutrition is a crucial and prevalent drawback affecting 16% to 70% of dialysis sufferers, relying on the examine inhabitants and evaluation process [1–3]. In dialysis sufferers, inadequate dietary consumption, compromised scientific well-being, comorbidity and dialysis associated elements can result in poor dietary standing [4–6]. Poor dietary standing is on its flip related to impaired practical capability, elevated threat of problems, decrease high quality of life and restricted survival [3, 7–9]. Due to this fact it appears necessary to determine sufferers in danger for malnutrition already at an early stage, with the intention to begin interventions to enhance their dietary standing and scientific and psychological end result. Most pointers due to this fact suggest to judge dietary standing in dialysis sufferers [10–12]. Dietary standing of dialysis sufferers can change quickly, so frequent analysis is required. Goal standardized evaluation of dietary standing in dialysis sufferers may be laborious, logistically troublesome, time consuming and thus costly, so there’s a want for an correct and dependable screening instrument that may routinely be utilized on the bedside on a repetitive foundation. An sufficient dietary evaluation instrument ought to meet a number of important standards: (1) diagnose malnutrition precisely, (2) detect adjustments in dietary standing over time, (3) be related to morbidity and mortality and (4) consider the impression of a dietary intervention [9]. A number of scoring programs have been developed to estimate dietary standing primarily based on available parameters. The Mini Dietary Evaluation rating (MNA) might be probably the most broadly used and finest validated rating in numerous aged populations and settings [13–15]. The instrument consists of a 6-item quick kind screening instrument (MNA-SF) included within the 18-item lengthy kind scale (MNA-LF). In keeping with the directions of the MNA rating, no additional analysis by the total rating is required when sufferers are rated as “regular diet” by the MNA-SF, because the rating has a excessive unfavourable predictive worth for malnutrition. This makes the instrument ideally fitted to fast screening, as could be the case for normal follow-up in dialysis sufferers. Nonetheless, when the MNA-SF signifies ‘prone to malnutrition’ or ‘malnourished’, additional evaluation by the total model is required to substantiate the prognosis. Analysis exhibits the MNA has robust sensitivity, specificity and predictive worth for malnutrition [13, 14, 16]. A number of of the objects within the MNA scale are nevertheless more likely to have a unique which means in a dialysis cohort as in comparison with a extra common inhabitants, such because the objects on protein consumption, fluid consumption or consumption of fruit and greens. As a consequence, validation and eventual recalibration of the MNA rating in a dialysis cohort is important.

The goal of this examine is due to this fact 1/ to judge the affiliation of the MNA-SF and MNA-LF with 2 12 months mortality within the dialysis inhabitants; 2/ to judge the unfavourable predictive worth for threat for malnutrition/malnutrition of the rating “regular dietary standing” of the MNA-SF; 3/ to discover eventual want for recalibration of the MNA-LF.


Examine design and topics

For this cross-sectional multicentric examine with longitudinal observe up, all consecutive grownup (>18 years) dialysis sufferers of the hemodialysis items of the Ghent College Hospital and Antwerp College Hospital (Belgium) have been eligible. The Ghent College Hospital has 3 massive satellite tv for pc hemodialysis items, a unit for nocturnal hemodialysis and a peritoneal dialysis programme, and likewise these sufferers have been eligible for inclusion. Evaluation of sufferers with acute inflammatory illness and/or who underwent latest (<3 weeks) surgical procedure was postponed till their situation was stabilized. Being pregnant, substantial cognitive impairment and never with the ability to perceive Dutch have been exclusion standards. Sufferers have been included in numerous waves, ranging from November 2015, and adopted up prospectively till loss of life or finish of examine (January 9, 2019). The examine was accredited by the Moral Committee of the Ghent College Hospital and the Moral Committee of the Antwerp College Hospital and written knowledgeable consent was obtained from every participant (undertaking quantity Ghent B670201525559, and Antwerp B300201422642). Registration quantity on NTC03910426.

Questionnaires and scores

The Mini Dietary Evaluation (MNA)

The MNA is a validated instrument initially developed to evaluate dietary standing in aged sufferers and is especially indicated for analysis settings [13, 17]. The instrument accommodates 18 objects and evaluates 4 totally different features: anthropometric evaluation (physique mass index (BMI), weight reduction, and arm and calf circumferences); common evaluation (way of life, remedy, mobility and presence of indicators of despair or dementia); quick dietary evaluation (variety of meals, meals and fluid consumption and autonomy of feeding); and subjective evaluation (self-perception of well being and diet). By including up the scores, labelled as MNA-LF, people may be divided in 3 teams utilizing threshold values of <17 for ‘malnourished’, 17–23.5 for ‘prone to malnutrition’ and ≥ 24 for ‘regular dietary standing’, with a most whole rating of 30 factors [13]. As we made the speculation {that a} recalibration of the MNA-LF in sufferers on dialysis may be warranted, we used additionally totally different lower offs for categorization. First, a categorization whereby the median rating of sufferers not within the ‘regular dietary standing’ group was used to separate them additional right into a ‘low threat of malnutrition’ and a ‘excessive threat of malnutrition’ group. This rating was labelled as MNA-LF-new. Second, considering that in dialysis sufferers the objects “consumption of fruit and greens” and “quantity of fluid consumption” may very well be ruled by elements apart from dietary consumption, we lowered the lower off for “regular dietary standing” to 22 (as an alternative of 24). This rating was labelled as MNA-LF-ESKD (MNA-LF-end stage kidney illness). The primary six objects (collectively 14 factors) of the MNA can be utilized as a brief screening instrument to categorise sufferers as having a standard dietary standing, a threat for malnutrition and malnutrition, with threshold values of >11, 8 and eight>, respectively. This rating was labelled as MNA-SF. In keeping with the directions of the screening take a look at, no additional analysis is required when sufferers classify as “regular dietary standing”. For the aim of this examine, we have now nevertheless additionally carried out the MNA-LF in sufferers with regular dietary standing within the quick kind, so as to have the ability to assess re-categorization between MNA-SF and the three MNA-LF scores.

Davies stoke rating

Comorbidity was assessed utilizing the Davies Stoke Rating [18]. This rating assigns 1 level for every of the next situations: malignancy, ischemic coronary heart illness, peripheral vascular illness, left ventricular dysfunction, diabetes mellitus, systemic collagen vascular illness, and different important pathologies that have an effect on survival within the common inhabitants. The grade of comorbidity is derived immediately from the full rating; Grade 0 (low threat) is a zero rating, grade 1 (medium threat) is a rating of 1–2, and grade 2 (excessive threat) a cumulative rating of ≥ 3. All parameters of the scores have been surveyed by a educated analysis nurse and entered immediately in a devoted database. Diabetes was outlined as sufferers taking a number of glycaemia reducing medication or food plan.


Biochemical information have been retrieved from the digital medical data on a date as shut as doable to the information of inclusion, with a most distinction of 4 weeks. Solely information collected on the midweek pre-dialysis session have been included.

End result

The survival length information have been calculated from the time of inclusion within the examine cohort to loss of life (occasion) or the tip of the remark interval, January 9, 2019 (censored). Last standing of all sufferers was derived from digital medical data as no sufferers have been misplaced to observe up throughout the remark interval.

Methodological high quality

Methodological high quality was assessed utilizing the Newcastle-Ottowa High quality Evaluation Kind for cohort research (NOS) [19].

Statistical evaluation

Steady variables have been summarized as imply ± normal deviation (SD). Chi sq. or A technique ANOVA was used to match variables over subgroups.

Survival in numerous teams have been calculated as time to occasion utilizing Cox proportional hazard fashions, and as two 12 months survival price utilizing logistic regression. Outcomes are offered as hazard ratios (HR) with 95% confidence intervals (CI).


Total, 216 sufferers (63.9% males, 36.2% girls, 38.9% with diabetes, age 67±15 years) have been included. The pattern is consultant for the dialysis inhabitants in Flanders [20], with 90.3% of them residing independently, 94.9% handled with hemodialysis and 5.1% with peritoneal dialysis.

The imply MNA-SF rating was 9.9±1.8, with 30.1%, 59.3% and 10.6% of sufferers being categorized as having regular dietary standing, in danger for malnutrition and malnourished, respectively ().

Our outcomes point out that MNA is strongly related to mortality in sufferers on dialysis, and may thus be seen as a legitimate assessor of dietary issues on this inhabitants. Categorization primarily based on the MNA-SF rating and on the MNA-LF rating correspond fairly properly, however solely when the precise options of the dialysis inhabitants are taken into consideration by barely recalibrating the cut-offs for the MNA-LF rating as was additionally confirmed by ROC curve evaluation. The MNA-SF rating may be carried out simply and quickly at bedside, and is thus an excellent screening instrument for use frequently within the dialysis affected person to detect sufferers in danger for malnutrition.

Malnutrition is a typical drawback in sufferers on dialysis, and is strongly related to mortality. Most scoring programs for malnutrition use parameters that may be much less dependable or much less consultant in sufferers on dialysis, and their relation with mortality on this inhabitants may be counterintuitive. Probably the most placing instance is the weight problems paradox that greater BMI seems to be protecting in sufferers on dialysis [5]. Due to this fact, it’s important that malnutrition scores are validated in dialysis sufferers, utilizing mortality as end result. Few research aimed to validate the MNA in ESKD inhabitants [21–24], and solely 2 research carried out survival evaluation. Brzozko et al. [23] recognized the next hazard of loss of life in PD sufferers categorized by the MNA-LF as prone to malnutrition or malnourished (HR 5.7, 95% CL 4.1–7.2). These outcomes have been confirmed after adjustment for demographics, comorbidities and laboratory values. Nonetheless, the authors solely assessed the dietary standing on a pattern of 41 sufferers. Santin et al. [24] examined the predictive validity of the MNA-SF in an aged HD inhabitants (≥ 60 years) and reported the next mortality threat in sufferers with a threat of malnutrition and malnourishment within the crude and adjusted fashions (HR 5.53, 95% CL 1.34–4.77: adjusted for age, gender, dialysis classic and diabetes). Our outcomes point out that MNA performs properly, and is related to survival in a dose-dependent means. Earlier work has already validated Subjective World Evaluation (SGA) [25] as a instrument to evaluate dietary standing in different settings, and likewise within the dialysis inhabitants [26]. In most research, SGA was related to mortality [24, 27, 28]. For these causes, SGA is beneficial by European Renal Greatest Observe as a great instrument to display screen dietary standing within the aged [10]. Nonetheless, SGA nonetheless may be criticized for its subjectivity, and thus potential issues for reproducibility [28, 29], and several other authors report totally different outcomes on the affiliation of SGA with extra goal dietary markers [30, 31]. Additional SGA takes a while and experience to be evaluated, making it much less appropriate in actual fact for routine use as a daily screening instrument in a busy dialysis unit. To be used in sufferers on dialysis, one other Protein Vitality Losing (PEW) rating was developed primarily based on the ARNOS cohort [32]. This rating, graded from 0 (worse) to 4 (finest) was derived from 4 totally different features of diet: serum albumin, physique mass index, a normalized serum creatinine worth, and protein consumption as assessed by normalized Protein derived Nitrogen Look (nPNA) [10, 11]. This rating was related to survival at 3.5 12 months, and this in a dose dependent method: there was a discount in survival (5%-7%; P < 0.01) for every unit decrement within the rating grade. As well as, the 6-month variation of this PEW rating on reassessment additionally strongly predicted sufferers' survival (P<0.01) [32]. In concept, repetitive dedication of this PEW rating could also be of assist to raised determine subgroups of sufferers in danger for malnutrition, and wherein diet assist needs to be enforced. Nonetheless, evaluation of nPNA is in follow quite laborious, and it's due to this fact unclear whether or not this rating can be utilized in on a regular basis follow.

As dietary standing of dialysis sufferers can change quickly over time, common screening and observe up is important. Nonetheless, most dietary evaluation instruments are cumbersome, want specialised personnel or gear, or are merely time consuming, and may due to this fact not be used as repetitive, routine instruments.

Our outcomes point out that MNA performs as properly when solely the quick kind is carried out. This quick screening half consists of 6 questions that may simply and quickly be accomplished at bedside, with none further instrument or gear. Additional refinement in sufferers in danger may very well be carried out through the use of e.g. a PEW scoring as primarily based on ARNOS cohort [32].

Categorization of dietary standing as primarily based on the MNA quick kind appeared to have the strongest correlation with mortality, even stronger than the total rating of MNA. This may be defined by the precise scenario of dialysis sufferers, ensuing that some domains within the lengthy type of the MNA rating don’t add to its discriminative energy. The objects “fluid consumption” and “consumption of fruit and greens” should not consultant in dialysis sufferers, as these should not associated to lower in meals consumption, however are pressured by dietary restrictions linked to being a dialysis affected person. The merchandise “takes greater than 3 medication/day” is just not discriminatory in dialysis sufferers, as that is the case in practically all sufferers. This assumption is supported by research discovering low settlement between SGA and MNA [21, 22, 24]. The noticed low Cohen’s kappa scores may very well be attributed to the generalizability of the 2 scores outdoors their unique goal inhabitants. The SGA has already been validated extensively in adults on hemodialysis and due to this fact is acknowledged as being relevant on this inhabitants. The MNA nevertheless was developed for the aged generally and is thus not on itself tailored to an ESKD inhabitants. Due to this fact, the categorization primarily based on the MNA-LF rating in all probability wants some recalibration within the setting of dialysis sufferers. Based mostly on Receiver Working Traits evaluation and on the reasoning that it’s in actual fact for many dialysis sufferers inconceivable to get 2 factors (fluid, and fruit and greens), it appears cheap to make use of 22 factors because the cut-off between regular dietary standing and being in danger for malnutrition. When this categorization criterion is utilized, the screening rating and full rating seem like very properly matched, with only a few sufferers re-categorized. This additional strengthens that the screening rating could be very performant to determine sufferers with a questionable dietary standing, and {that a} regular rating is reassuring.

The strengths of this examine are the provision of the arduous end result of mortality, the potential assortment of knowledge, and the comparatively lengthy observe up time, with a imply of two years. Our inhabitants can be consultant for the common dialysis unit in Flanders, with a great mixture of sufferers on daytime dialysis in hospital in addition to in satellite tv for pc dialysis items, sufferers on nocturnal dialysis and peritoneal dialysis. Additional, with a NOS-score of 8 level, our examine may be thought-about as a ‘good high quality’ examine when making use of the standards urged by McPheeters et al. [33] (S1 Materials).

A limitation is after all the observational nature of our examine. It’s accordingly not doable to evaluate whether or not bettering dietary standing in sufferers in danger for malnutrition can even successfully lead to enchancment of outcomes.

In conclusion, sustaining a great dietary well being in sufferers on dialysis may very well be an important factor within the prevention of deteriorating well-being, and due to this fact dietary standing requires shut consideration. By making use of survival evaluation, this present examine signifies that MNA-SF is an acceptable evaluation instrument for figuring out dietary issues in dialysis sufferers. Furthermore the feasibility of the instrument makes it simple to combine dietary evaluation in routine care.
