Quantifying the Time Used for Renal Dietitian's Responsibilities: A Pilot Study

Dietitians' practices in dialysis units in Brazil: nutritional assessment and intervention

INTRODUCTION

The importance of dietitians in dialysis units is indisputable and mandatory in Brazil, but little is known about the practices adopted by these professionals.

OBJECTIVE

To know practices adopted in routine nutritional care, focusing on nutritional assessment tools and treatment strategies for people at risk or diagnosed with malnutrition.

METHODOLOGY

Electronic questionnaire disseminated on social media and messaging applications. It included questions that covered dietitians' demographic and occupational profile characteristics and of the dialysis unit, use and frequency of nutritional assessment tools, nutritional intervention strategies in cases of risk or diagnosis of malnutrition, prescription and access to oral supplements.

RESULTS

Twenty four percent of the Brazilian dialysis units (n = 207) responded electronically. The most used nutritional assessment tools with or without a pre-established frequency were dietary surveys (96%) and Subjective Global Assessment (83%). The strategies in cases of risk or presence of malnutrition used most frequently (almost always/always) were instructions to increase energy and protein intake from foods (97%), and increasing the frequency of visits (88%). The frequency of prescribing commercial supplements with standard and specialized formulas was quite similar. The availability of dietary supplements by the public healthcare system to patients varied between regions.

CONCLUSION

Most dietitians use various nutritional assessment tools and intervention strategies in cases of risk or malnutrition; however, the frequency of use of such tools and strategies varied substantially.

Changes in US Dialysis Dietitian Responsibilities and Patient Needs During the COVID-19 Pandemic

OBJECTIVE

This study described the job responsibilities and modalities of care among dialysis dietitians in the United States and their observations regarding the nutrition needs of their patients, during the COVID-19 pandemic.

DESIGN AND METHODS

Cross-sectional online survey captures dietitian characteristics and responsibilities, dialysis facility characteristics, and patient needs. We recruited US dialysis dietitians. We used chi-square tests to compare respondent stress and facility-level policies regarding eating/drinking and oral nutrition supplements based on facility ownership type.

RESULTS

We received 191 complete or partial survey responses. Sixty-three percent of respondents stated that their center banned eating/drinking during dialysis due to COVID-19 masking policies. DaVita and non-profit facilities were significantly more likely to still allow eating/drinking during dialysis (31% and 29%, respectively) compared to Fresenius facilities (7%). A common theme in open-ended responses regarding nutrition care for COVID-19-positive patients was providing less care to these patients. A majority of respondents admitted to stress from working in healthcare during COVID-19. The majority of respondents indicated that patients were taking precautions such as having a family member or friend grocery shop for them (69%) or going to the store less often (60%). Just over a quarter of respondents indicated that affordability of food was a concern among patients. Seventy-two percent reported that patients were cooking at home more often, 60% had observed an increase in serum phosphorus, and 72% an increase in interdialytic weight gain.

CONCLUSIONS

Due to the increased risk of malnutrition and symptoms that can affect dietary intake in COVID-positive patients, and the economic conditions leading to increased rates of food insecurity, dietitians must be proactive in preventing and/or treating malnutrition through adequate protein and energy intake. Eating/drinking bans should not become permanent and dialysis centers should take precautions to allow intradialytic meals and oral nutrition supplement protocols to continue during the pandemic.

Workforce needs and estimated costs/savings for nutrition care in chronic kidney disease-stage 3 through maintenance dialysis

The role of nutrition in chronic kidney disease (CKD) is well known. However, controversies, misconceptions, and gaps in the literature exist regarding the workforce required to provide nutrition care in CKD. This paper reviews the existing literature on this topic, focusing primarily on the United States. Topics covered in this review include the qualifications and services of the registered dietitian nutritionist (RDN), to which specific patients nutrition care should be provided in CKD and on dialysis, barriers to the utilization of nutrition services, the quantity of nutrition care needed to improve patient outcomes, and the risks of provider burnout. Controversies include whether more staffing is associated with better care and the best measures of staffing. The topics are supported with estimations for the economic impact and practicality of workforce decisions.

A qualitative exploration of dietitians' experiences of prescribing oral nutritional supplements to patients with malnutrition: A focus on shared tailoring and behaviour change support

BACKGROUND

Oral nutritional supplements (ONS) are commonly prescribed to patients with malnutrition. Dietitians have been suggested as preferred prescribers but generally lack ONS prescribing rights. How dietitians with prescribing rights experience their professional practice of prescribing ONS remains understudied. Thus, by exploring dietitians' experiences of prescribing ONS, the present study aimed to obtain a deeper understanding of specific aspects that are of importance for dietitians when providing a nutrition therapy including ONS.

METHODS

Qualitative individual interviews were conducted with 13 dietitians prescribing ONS to free-living adult outpatients with malnutrition or at nutritional risk in the hospital or primary care setting. Systematic text condensation was used for data analysis.

RESULTS

Two main categories signifying important aspects were identified and labelled: 'Shared tailoring of the ONS prescription' and 'Supporting and facilitating ONS use'. First, the dietitians described tailoring the ONS prescription together with the patient, having their acceptance as a prerequisite, and being flexible regarding products and amounts prescribed. Second, they described performing different communication strategies and organising of practical issues (e.g., ONS delivery and support from others) to support and facilitate patients' ONS usage.

CONCLUSIONS

The present study identifies patient involvement and the role of dietitians as behaviour change facilitators as two important aspects when dietitians prescribe ONS. These findings allow for dietitians' ideals and strategies on how to prescribe ONS to be made more visible, which can inform both clinical practice and clinical trials for future improvements in nutrition therapy to address malnutrition.

Effect of Phosphate-Specific Diet Therapy on Phosphate Levels in Adults Undergoing Maintenance Hemodialysis: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Hyperphosphatemia is a persistent problem in individuals undergoing maintenance hemodialysis, which may contribute to vascular and bone complications. In some dialysis centers, dietitians work with patients to help them manage serum phosphate. Given the regularity of hyperphosphatemia in this population and constraints on kidney dietitian time, the authors aimed to evaluate the evidence for this practice.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

There was a systematic review and meta-analysis of clinical trials. MEDLINE, Embase, CINAHL, Web of Science, Cochrane Central Register of Controlled Trials, and other databases were searched for controlled trials published from January 2000 until November 2019 in the English language. Included studies were required to examine the effect of phosphate-specific diet therapy provided by a dietitian on serum phosphate in individuals on hemodialysis. Risk of bias and certainty of evidence were assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) method.

RESULTS

Of the 8054 titles/abstracts identified, 168 articles were reviewed, and 12 clinical trials (11 randomized, one nonrandomized) were included. Diet therapy reduced serum phosphate compared with controls in all studies, reaching statistical significance in eight studies, although overall certainty of evidence was low, primarily due to randomization issues and deviations from protocol. Monthly diet therapy (20-30 minutes) significantly lowered serum phosphate in patients with persistent hyperphosphatemia for 4-6 months, without compromising nutrition status (mean difference, -0.87 mg/dl; 95% confidence interval, -1.40 to -0.33 mg/dl), but appeared unlikely to maintain these effects if discontinued. Unfortunately, trials were too varied in design, setting, and approach to appropriately pool in meta-analysis, and were too limited in number to evaluate the timing, dose, and strategy of phosphate-specific diet therapy.

CONCLUSIONS

There is low-quality evidence that monthly diet therapy by a dietitian appears to be a safe and efficacious treatment for persistent hyperphosphatemia in patients on HD.

Registered Dietitian Staffing in Dialysis: Impact on Quality Ratings in Mandate and Nonmandate States

OBJECTIVE

Texas is the only state to mandate a patient to full-time equivalent (FTE) registered dietitian (RD) ratio (<125 patients:FTE RD) in dialysis. Little research exists about the relationship between patient:FTE RD ratio and quality. Our objectives were to a) examine the effect of the mandate on patient:FTE RD ratios in Texas facilities compared to similar nonmandated facilities and b) examine the association between patient:FTE RD ratio and the patient rating of staff quality or star rating of the facility.

DESIGN AND METHODS

Using data from Dialysis Facility Annual Reports, we excluded facilities with less than 125 patients and matched based on region, chain/profit status, and number of patients, pairing each Texas facility with 2 non-Texas facilities. T-tests for difference of means and chi-square tests were performed to compare facility groups characteristics and assess mandate impact. We used correlation between patient:FTE RD ratio and staff quality linearized score, and ANOVA to compare patient:FTE RD ratios between the star rating levels.

RESULTS

The patient:FTE RD ratio was higher in non-Texas than Texas facilities (111.84 ± 40.70 vs 90.80 ± 24.02, P < .01). The Pearson correlation between patient:FTE RD ratio and linearized score rating of the dialysis center staff was essentially nonexistent (r = -0.046). We found a trend of higher patient:FTE RD ratios in facilities with lower star ratings for quality and staff but no statistical significance.

CONCLUSION

The mandate effectively lowered the patient:FTE RD ratio in Texas dialysis facilities with over 125 patients, indicating that states considering such a mandate may benefit from implementing it. We found no association between patient:FTE RD staffing and quality, either objectively or via patient assessment. Further research should examine whether dialysis facilities are trending toward smaller patient sizes to circumvent staffing mandates and examine the relationship between other professions' staffing ratios and quality.
