Demographic and occupational profile of dietitians working in dialysis centers in Brazil

INTRODUCTION

In 2004, the Ministry of Health stipulated that dialysis centers were required to have at least one dietitian on their staff. However, the regulation did not include recommendations regarding the number of dietitians or the workload based on the number of patients assisted.

OBJECTIVE

To describe the demographic and occupational profiles of dietitians working in dialysis centers in Brazil.

METHODOLOGY

An electronic questionnaire was disseminated in social media and messaging apps with questions about the demographic and occupational profile of dietitians working in dialysis centers and matters related to patient care.

RESULTS

A total of 207 questionnaires were answered, covering 24% of the dialysis centers in Brazil. More than half of the dietitians (58%) had worked for more than five years in dialysis centers, and 83% reported additional training in Nephrology. The median (interquartile range) number of patients per monthly working hour was 1.6 (1.0-2.3). Considering all dialysis centers, 64% of the patients were seen at least once a month. Differences in demographic/occupational profiles and patient care were associated with workload, the main source of dialysis funding, and Brazilian geographical region.

CONCLUSION

Most dietitians were experienced and trained in Nephrology. Substantial variability was found in the number of patients per dietitian workload, and proportion of patients receiving monthly nutritional care. Further studies are needed to discuss the demands of dietitians, dialysis centers, and patients.

Telehealth strategies in the care of people with chronic kidney disease: integrative review

OBJECTIVE

to evaluate the evidence about telehealth strategies in caring for people with chronic kidney disease.

METHOD

integrative literature review. The search for primary studies was carried out in six databases: PubMed/MEDLINE, Web of Science, EMBASE, CINAHL, LILACS, and Scopus. The sample consisted of 48 articles published between 2000 and 2021. The telehealth strategy was applied by a multidisciplinary team of doctors, nurses, pharmacists, nutritionis, and social workers. The type of study, country, strategy applied, setting, population, and professional were extracted from the articles. The studies were selected by reading the title and abstract (phase 1) and then reading them in full (phase 2), categorizing them by telehealth strategy. The results were summarized descriptively and the studies were classified according to their level of evidence.

RESULTS

the home was the most representative in dialysis and conservative treatment. Six categories of telehealth strategies were identified: remote monitoring devices, teleconsultation, digital platforms, apps, multimodality strategies, and telephone contact.

CONCLUSION

using these strategies for the care of people with chronic kidney disease presents different forms and implementations, being feasible for the renal population at any stage of the disease and applicable by different health professionals with an emphasis on the home environment. The evidence shows that telehealth favors lower cost, accessibility to remote locations, and better monitoring of dialysis with positive resul in symptom control, risk reduction, and patient training.

BACKGROUND

Telehealth in chronic kidney disease care is feasible and promising. (2) Telehealth is feasible for people at all stages of CKD. (3) Health promotion and monitoring were the most applied by telehealth. (4) Remote care can reduce costs, emergencies, and contac with the clinic. (5) Nurses mainly used telephone contact and teleconferencing.

Hospitalization and mortality during the pandemic in chronic hemodialysis patients and the general population in Peru

BACKGROUND

Patients with chronic kidney disease have a higher risk of severe disease and mortality from COVID-19 than the general population.

OBJECTIVE

To compare hospitalization and mortality rates during the pandemic among chronic hemodialysis (HD) patients and the general population in Lima (Peru).

METHODS

This retrospective cohort included an assessment of the database of chronic HD patients of the health service providers of the social health insurance benefit networks of Lima and Callao between 2019 and 2021. Hospitalization and mortality rates were obtained for every 1,000 individuals, and variations in the percentages of COVID-19 cases and deaths were calculated. These rates were compared with those of the general population data and standardized by age and sex.

RESULTS

An average of 3,937 chronic HD patients were evaluated each month. Of these, 4.8% had COVID-19 and 64.97% were mild cases. The hospitalization rates per 1,000 patients were 19.5, 29.28, and 36.7 in 2019, 2020, and 2021, respectively. The mortality rates per 1,000 patients were 5.9, 9.74, and 11.49 in 2019, 2020, and 2021, respectively. When compared to the standardized general population, the peaks of both rates coincided with the plateaus of the waves during the pandemic. The hospitalization rate for COVID-19 was 12 times higher in HD patients than in the general population, and the mortality rate for COVID-19 was twice as high.

CONCLUSION

HD patients had higher hospitalization and standardized mortality rates than the general population. Peaks in hospitalizations and mortality coincided with the plateaus of the first and second waves of the pandemic.

The challenges of the pandemic and the vaccination against covid-19 in pediatric patients with kidney disease

The covid-19 vaccine confers direct protection and reduces transmission rates of the virus and new variants. Vaccines from Pfizer/BioNTech and CoronaVac have been cleared for children in Brazil. They are safe, effective, and immunogenic. There are no known complications associated with the use of steroids or vaccines in pediatric patients with covid-19 and nephrotic syndrome. With or without immunosuppression, these patients are not at increased risk of severe covid-19, and steroids are safe for them. A milder form of covid-19 occurs in patients with chronic kidney disease without the need for hospitalization. The vaccine response may be reduced and/or the duration of antibodies after vaccination may be shorter than in the general population. However, considering risk of exposure, vaccination against covid-19 is recommended. It is believed that patients with hemolytic-uremic syndrome are at higher risk of severe covid-19. Vaccination is recommended, although specific data on the safety and efficacy of the covid-19 vaccine are limited. There is agreement that the benefits of induced immunity outweigh the risks of immunization. Vaccination against covid-19 is recommended for children and adolescents needing kidney transplantation or who have undergone transplantation. These patients present decreased immune response after vaccination, but immunization is recommended because the benefits outweigh the risks of vaccination. Current recommendations in Brazil stipulate the use of the messenger RNA vaccine. This paper aims to provide pediatric nephrologists with the latest knowledge about vaccination against covid-19 for children with kidney disease.

Factors associated with the safety culture of patients under dialysis in the context of the COVID-19 pandemic

OBJECTIVES

to assess the factors associated with the safety culture of patients under dialysis in the context of the COVID-19 pandemic.

METHODS

a cross-sectional and analytical study, carried out in Minas Gerais, with 134 professionals from three dialysis services. The Hospital Survey on Patient Safety Culture, adapted for Brazil, was used.

RESULTS

only variable type of management was associated with the highest percentage of positive response in public and private services. Patient safety was rated as good by 55.7% of respondents. In dimension assessment, the public service presented one strength and five weaknesses, the private service did not present weak areas, and the philanthropic service presented a weakness. The priority areas for improvement actions are represented by dimensions "Nonpunitive response to error" and "Staffing".

CONCLUSIONS

interventions should consider the type of service management, as it is a factor associated with safety culture.

Dialysis-related constrictive pericarditis: old enemies may sometimes come back

Cardiovascular disease is the main cause of death in patients with chronic kidney disease (CKD). Several heart conditions have been associated with CKD, including myocardial and pericardial diseases. This paper describes a case of Dialysis-related constrictive pericarditis in a patient diagnosed with sudden hypotension during a hemodialysis session. A 65-year-old man diagnosed with hypertension, diabetes, obesity, and cirrhosis on hemodialysis for two years complained of symptoms during one of his sessions described as malaise, lipothymia, and confusion. The patient had a record of poor compliance with the prescribed diet and missed dialysis sessions. He was sluggish during the physical examination, and presented hypophonetic heart sounds, a blood pressure of 50/30mmHg, and a prolonged capillary refill time. The patient was referred to the intensive care unit and was started on antibiotics and vasoactive drugs. His workup did not show signs of infection, while electrocardiography showed low QRS-wave voltage. His echocardiogram showed signs consistent with a thickened pericardium without pericardial effusion. Cardiac catheterization showed equalization of diastolic pressures in all heart chambers indicative of constrictive pericarditis. The patient underwent a pericardiectomy. Examination of surgical specimens indicated he had marked fibrosis and areas of dystrophic calcification without evidence of infection, consistent with Dialysis-related constrictive pericarditis. Hypotension for unknown causes must be considered in the differential diagnosis of dialysis patients.

Clinical outcomes of COVID-19 in patients undergoing chronic hemodialysis and peritoneal dialysis

BACKGROUND

The reported incidence and fatality rate of the severe acute respiratory syndrome coronavirus 2 in patients receiving chronic dialysis are higher than in the general population. We sought to study the outcomes following coronavirus disease 2019 (COVID-19) diagnosis in patients undergoing chronic hemodialysis (HD) or peritoneal dialysis (PD) in a single center in Brazil.

METHODS

Of the 522 patients on dialysis evaluated between March 1, 2020, and October 1, 2021, those presenting symptoms or with a history of close contact with COVID-19 patients were tested with reverse-transcription polymerase chain reaction of samples from nasopharyngeal swabs.

RESULTS

Of the 522 patients, 120 were positive for COVID-19 infection, of which 86% were on HD and 14% in the PD program. The incidence per 10,000 inhabitants was higher in the HD group than in the PD group (2,423.5 vs. 1,752.5). The mortality per 10,000 inhabitants (470.5 vs. 927.8) and the fatality rate (19.4 vs. 52.9%, p = 0.005) were higher in the PD group. The PD group also had a higher need for hospitalization, intensive care, and mechanical ventilation.

CONCLUSIONS

We advise caution when considering strategies to transfer patients from HD to the PD program to minimize the risk of COVID-19 for patients on HD.

Multidisciplinary treatment for patients with chronic kidney disease in pre-dialysis minimizes costs: a four-year retrospective cohort analysis

INTRODUCTION

Chronic kidney disease (CKD) can progress to end-stage renal disease (ESRD), and clinical studies show that this progression can be slowed. The objective of this study was to estimate the costs to Brazil's public health system (SUS) throughout the course of CKD in the pre-dialysis stage compared to the costs to the SUS of dialysis treatment (DT).

METHODS

A retrospective cohort study was conducted to analyze clinical and laboratory variables; the outcome analyzed was need for DT. To assess cost, a microcosting survey was conducted according to the Methodological Guidelines for Economic Evaluations in Healthcare and the National Program for Cost Management, both recommended by the Brazilian Ministry of Health for economic studies.

RESULTS

A total of 5,689 patients were followed between 2011 and 2014, and 537 met the inclusion criteria. Average costs increased substantially as the disease progressed. The average cost incurred in stage G1 in Brazilian reals was R$ 7,110.78, (US$1,832.06) and in stage G5, it was R$ 26,814.08 (US$6,908.53), accumulated over the four years.

CONCLUSION

A pre-dialysis care program may reduce by R$ 33,023.12 ± 1,676.80 (US$ 8,508.26 ± 432.02) the average cost for each year of DT avoided, which is sufficient to cover the program's operation, minimizing cost. These results signal to public health policy makers the real possibility of achieving significant cost reduction in the medium term for CKD care (4 years), to a program that disbursed R$ 24 billion (US$ 6.8 billion) for DT in Brazil between 2009 and 2018.

Is the Fistula First Approach still valid?

The Fistula First Breakthrough Initiative, founded in 2003, was responsible for changing the access profile in the United States, increasing the prevalence of arteriovenous fistulas (AVFs) by 50% and reducing that of arteriovenous grafts (AVGs). However, the concept that AVFs are always the best access for all patients has been challenged. Discussion points are: (1) the questionable survival benefit of AVFs over AVGs, if one takes into account the high rates of primary AVF failure; (2) the potential benefits of using AVGs for greater primary success; and (3) the questionable benefit of AVFs over AVGs in patients with shorter survival, such as the elderly. The high rate of primary failure and maturation procedures leads to prolonged use of catheters, and it is one of the weaknesses of the fistula first strategy. AVGs proved to be better than AVFs as a second access after the failure of a first AVF, and in patients with non-ideal vessels, with greater primary success and reduced catheter times. AVGs appear to have a similar survival to AVFs in patients older than 80 years, with less primary failures and interventions to promote maturation. The most recent KDOQUI guidelines suggest an individualized approach in access planning, taking into account life expectancy, comorbidities and individual vascular characteristics, with the aim of chosing adequate access for the right patient, at the right time, for the right reasons.

Covid-19 pandemic: from carnival masks to surgical masks

Given the high transmissibility of SARS-CoV-2, COVID-19 pandemic has a huge impact on our health system. Even in developed countries, strategic resources soon become insufficient. Although people over 60 and with comorbidities are at greater risk of developing severe forms, younger people may also require precious and scarce care. Hence, the World Health Organization recommend tests - PCR and serological tests - for detecting infected people on a large scale. The most common symptoms are fever, fatigue, dry cough, anorexia, myalgia, and dyspnea, with tomographic pulmonary findings being frequent even in asymptomatic cases. The Brazilian Society of Nephrology has published guidelines for the management of hypertensive, diabetic, dialysis, and transplant patients. In its alerts, care and precautions in dialysis units are also being detailed, both for the health team and for the patients. Although important renal manifestations are not yet evident in the admission of positive cases, recent studies with renal patients and performed in nephrology services are listed here. This pandemic lead us to learn from its progress in order to face new challenges in dialysis clinics, transplant services, and intensive care services.
