RESUMO
ABSTRACT: Worldwide the assistance on renal replacement therapy (RRT) is carried out mainly by private for-profit services and in a market with increase in mergers and acquisitions. The aim of this study was to conduct an integrative systematic review on privatization and oligopolies in the RRT sector in the context of contemporary capitalism. The inclusion criteria were scientific articles without language restrictions and that addressed the themes of oligopoly or privatization of RRT market. Studies published before 1990 were excluded. The exploratory search for publications was carried out on February 13, 2024 on the Virtual Health Library Regional Portal (VHL). Using the step-by-step of PRISMA flowchart, 34 articles were retrieved, of which 31 addressed the RRT sector in the United States and 26 compared for-profit dialysis units or those belonging to large organizations with non-profit or public ones. The main effects of privatization and oligopolies, evaluated by the studies, were: mortality, hospitalization, use of peritoneal dialysis and registration for kidney transplantation. When considering these outcomes, 19 (73%) articles showed worse results in private units or those belonging to large organizations, six (23%) studies were in favor of privatization or oligopolies and one study was neutral (4%). In summary, most of the articles included in this systematic review showed deleterious effects of oligopolization and privatization of the RRT sector on the patients served. Possible explanations for this result could be the presence of conflicts of interest in the RRT sector and the lack of incentive to implement the chronic kidney disease care line. The predominance of articles from a single nation may suggest that few countries have transparent mechanisms to monitor the quality of care and outcomes of patients on chronic dialysis.

BACKGROUND Although approximately 25% of Brazilians have private health coverage (PHC), studies on the surveillance of chronic kidney disease (CKD) in this population are scarce. The objective of this study was to estimate the prevalence of CKD in individuals under two PHC regimes in Brazil, who total 8,335,724 beneficiaries. METHODS Outpatient serum creatinine and proteinuria results of individuals from all five regions of Brazil, ≥18 years of age, and performed between 10/01/2021 and 10/31/2022, were analyzed through the own laboratory network database. People with serum creatinine measurements were evaluated for the prevalence and staging of CKD, and those with simultaneous measurements of serum creatinine and proteinuria were evaluated for the risk category of the disease. CKD was classified according to current guidelines and was defined as a glomerular filtration rate (GFR)<60 ml/min/1.73 m² estimated by the 2021 CKD-EPI equation. RESULTS The number of adults with serum creatinine results was 1,508,766 (age 44.0 [IQR, 33.956.8] years, 62.3% female). The estimated prevalence of CKD was 3.8% (2.6%, 0.8%, 0.2% and 0.2% in CKD stages 3a, 3b, 4 and 5, respectively), and it was higher in males than females (4.0% vs. 3.7%, p<0.001, respectively) and in older age groups (0.2% among 18-29-year-olds, 0.5% among 30-44-year-olds, 2.0% among 45-59-year-olds, 9.4% among 60-74-yearolds, and 32.4% among ≥75-year-olds, p<0.001) Adults with simultaneous results of creatinine and proteinuria were 64,178 (age 57.0 [IQR, 44.867.3] years, 58.1% female). After adjusting for age and gender, 70.1% were in the low-risk category of CKD, 20.0% were in the moderate-risk category, 5.8% were in the high-risk category, and 4.1% were in the very high-risk category. CONCLUSION The estimated prevalence of CKD was 3.8%, and approximately 10% of the participants were in the categories of high or very high-risk of the disease. While almost 20% of beneficiaries with PHC had serum creatinine data, fewer than 1% underwent tests for proteinuria. This study was one of the largest ever conducted in Brazil and the first one to use the 2021 CKD-EPI equation to estimate the prevalence of CKD.

RESUMO
INTRODUCTION: This study aimed to compare the characteristics and outcomes of critically ill patients with COVID-19-associated acute kidney injury (AKI) who were treated with kidney replacement therapy (KRT) in the first and second waves of the pandemic in the megalopolis of Sao Paulo, Brazil. METHODS: A multicenter retrospective study was conducted in 10 intensive care units (ICUs). Patients aged ≥18 years, and treated with KRT due to COVID-19-associated AKI were included. We compared demographic, laboratory and clinical data, KRT parameters and patient outcomes in the first and second COVID-19 waves. RESULTS: We assessed 656 patients (327 in the first wave and 329 in the second one). Second-wave patients were admitted later (7.1±5.0 vs. 5.6±3.9 days after the onset of symptoms, p<0.001), were younger (61.4±13.7 vs. 63.8±13.6 years, p = 0.023), had a lower frequency of diabetes (37.1% vs. 47.1%, p = 0.009) and obesity (29.5% vs. 40.0%, p = 0.007), had a greater need for vasopressors (93.3% vs. 84.6%, p<0.001) and mechanical ventilation (95.7% vs. 87.8%, p<0.001), and had higher lethality (84.8% vs. 72.7%, p<0.001) than first-wave patients. KRT quality markers were independently associated with a reduction in the OR for death in both pandemic waves. CONCLUSIONS: In the Sao Paulo megalopolis, the lethality of critically ill patients with COVID-19-associated AKI treated with KRT was higher in the second wave of the pandemic, despite these patients being younger and having fewer comorbidities. Potential factors related to this poor outcome were difficulties in health care access, lack of intra-hospital resources, delay vaccination and virus variants.

INTRODUÇÃO: A nefropatia induzida por contraste (NIC) é uma complicação dos procedimentos angiográficos que requerem a administração de meios de contraste. Grandes volumes estão associados à NIC. Não está claro se o tipo de contraste interfere nessa diferença. OBJETIVO: Avaliar se o volume de contraste utilizado nos procedimentos percutâneos tem interação com o tipo de contraste (baixa ou isosmolar) no desenvolvimento de NIC. MÉTODOS: A NIC é definida como uma elevação de creatinina sérica de mais de 25% ou ≥0,5 mg/dl da basal após 48 h. Subanálise de estudo randomizado, centro único, incluindo 2268 pacientes consecutivos submetidos a procedimentos coronários diagnósticos e terapêuticos entre 2016 a 2018. Todos os procedimentos foram realizados com contraste de baixa osmolaridade ou iso-osmolar. A amostra foi dividida em 2 grupos em relação ao volume de 150ml de contraste. Análise estatística: para avaliar o efeito do contrate e do volume no NIC, utilizou-se um modelo de regressão logística com efeito de interação. Este modelo foi avaliado também ajustado para síndrome coronária aguda, disfunção ventricular, creatinina basal, sexo e idade. Os dados foram analisados com uso do software R versão 4.1.2. RESULTADOS: População predominantemente masculina, HAS (85%), DM (52%), DRC (31%). Modelo de regressão logística com efeito de interação entre contraste e volume (p>0,999). Modelos aditivos para NIC apresentado sem diferença entre os grupos (p= 0.974 e p= 0.202) ajustado para sexo, idade, creatinina basal, IC, SCA. CONCLUSÃO: Nesse estudo, mesmos nos casos em que maior quantidade de contraste foi utilizada, o tipo de contraste (iso-osmolar ou de baixa osmolaridade) não foi associado à ocorrência de NIC.

Chronic kidney disease (CKD) provides a worse prognosis for patients with heart disease. In Latin America, studies that analyzed the prevalence and risk stratification of CKD in this population are scarce. We aimed to evaluate CKD prevalence and risk categories in patients of a public referral cardiology hospital in São Paulo, Brazil. This was a cross-sectional study based on a laboratory database. Outpatient serum creatinine and proteinuria results performed between 1 January 2021 and 31 December 2021 were analyzed. CKD was defined by estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 and proteinuria, by the albumin/creatinine ratio in a spot urine sample (UACR) >30 mg/g. A total of 36,651 adults were identified with serum creatinine levels (median age 72.4 [IQR, 51.0-73.6] years, 51% male). Among them, 51.9% had UACR dosage (71.5% with UACR < 30 mg/g, 22.6%, between 30-300 mg/g, and 5.9% with UACR > 300 mg/g). The prevalence of CKD was 30.9% (15.3% stage 3a, 10.2% stage 3b, 3.6% stage 4, and 1.7% stage 5), and the distribution of patients in the risk categories of the disease was: 52.0% with low-risk, 23.5%, moderate risk, 13.0%, high risk, and 11.2%, very high. In an outpatient setting, the prevalence of CKD in cardiological patients was almost three times (31%) that of the general population; about half of the individuals evaluated (48%) were not screened for an important risk marker (proteinuria), and approximately a quarter of these patients (24%) were in the high or very high CKD risk categories.

BACKGROUND: Acute kidney injury (AKI) is a worldwide public health problem and is often treated by non-nephrologists. The objective of this study was to evaluate the knowledge of non-nephrologists, undergraduate medical students and health professionals regarding AKI. METHODS: An unsupervised and closed-response electronic questionnaire was sent to sixth-year medical students and non-nephrologist health professionals working in the city of São Paulo, Brazil. RESULTS: A total of 424 responses were returned from 650 invitations (40.1% males, 39.2% physicians, 34.0% senior medical students or resident physicians, 16.3% nurses and 10.6% pharma-cists). The knowledge of medical students and health professionals about the prevalence and lethality of AKI in hospitals ranged from 40.8% to 59.2%. The most recognized susceptibilities and risk factors for AKI were sepsis/septic shock (95.0%) and diabetes mellitus (91.3%); the less-recognized susceptibilities and risk factors were exposure to gadolinium-based contrast (23.3%) and chronic liver disease (55.7%). The study participants' rate of knowledge regarding the diagnosis of AKI was 50.973.6%, and their rate of knowledge regarding the criteria of increased serum creatinine and reduced urine volume was 52.6%. The most-recognized nephrotoxic medications were vancomycin (82.3%) and diclofenac (80.4%), and the least-recognized were acyclovir (34.0%) and cotrimoxazole (30.4%). The indications for emergency renal replacement therapy that were recognized by the study respondents were metabolic acidosis (82.3%), uremic syn-drome (81.6%), hyperkalemia unresponsive to clinical treatment (78.1%) and acute pulmonary edema (71.6%). CONCLUSION: The study showed knowledge gaps that can impact patient care and can be used to guide professional training programs.

INTRODUCTION: Chronic kidney disease and acute kidney injury (AKI) are important complications of heart diseases. In developing countries, epidemiological and cost information on the interaction of these conditions are scarce. OBJECTIVES: To determine the prevalence, costs and outcomes of patients admitted for acute coronary syndrome (ACS) with renal dysfunction and AKI. METHODS: The study was based on a prospective database analysis of patients admitted for ACS to a Brazilian public hospital specialized in cardiology between 7/16/2018 and 12/31/2019. Renal dysfunction was defined as an estimated glomerular filtration rate (eGFR) <60ml/min/1.73m² at hospital admission. Community-acquired and hospital-acquired AKI were defined as a fall and an increase of ≥0.3mg/dl in serum creatinine from baseline, respectively. RESULTS: 1295 of the 1620 patients had a confirmed diagnosis of ACS (median age 64.2 [56.5-70.6] years, 65.4% male, 82.7% had hypertension, 45.5% diabetes and 22.6% renal dysfunction). The imaging diagnosis of ACS was coronary angiography in 84.3% and the treatment was performed by angioplasty, only clinically and by myocardial revascularization in 47.3%, 40.0% and 12.7%, respectively. Hospital- and community-acquired AKI occurred in 43.9% and 2.3% of patients, respectively. Compared with patients admitted with eGFR ≥60ml/min/1.73m², those with eGFR <60 were older (70.6 vs. 62.5 years, p<0.001), had a higher prevalence of hypertension (92.1% vs. 80.0%, p<0.001) and diabetes mellitus (60.6% vs.54.5%, p=0.010), had a higher incidence of AKI (65.0% vs. 51.4%, p <0.001) and higher: median amount reimbursed for hospitalization (1,344 [366-2,103] vs. 1,334 [290-2,018] dollars, p=0.034), median length of stay (5 [3-10] vs. 4 [2-7] days, p<0.001), death within 30 days (4.1% vs. 1.4%, p=0.004) and death within 12 months (9.2% vs. 2.9%, p<0.001). Patients with AKI, compared to those without this condition, were older (65.6 vs.63.3 years, p=0.008), had lower eGFR on admission (78.1 ml/min/1.73m² vs.86.1 ml/min/1.73m², p<0.001) and greater: median amount reimbursed for hospitalization (1,334 [301-1,865] vs. 1,724 [973-2,549] dollars, p<0.001), median length of stay (6 [4-13] vs. 3 [2-5] days, p <0.001) and death within 12 months (4.8% vs. 2.3%, p=0.032). CONCLUSIONS: In patients with ACS at a cardiology referral hospital, renal dysfunction on admission and AKI during hospitalization were frequent and associated with worse clinical and economic outcomes.

INTRODUCTION: Chronic kidney disease (CKD) is common, preventable and silent in its early stages. Therefore, early detection of this condition in the population at risk, through laboratory tests, is essential. OBJECTIVES: To estimate the CKD prevalence and perform its risk stratification in a tertiary health service specialized in cardiology. METHODS: The study was cross-sectional and based on laboratory records of patients from a public hospital specialized in cardiology. The evaluated tests were serum creatinine and urinary albumin/creatinine ratio (ACR, random sample) performed on an outpatient basis between 01/01/2021 and 12/31/2021. Duplicate exams and patients under 18 years of age were excluded. The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI creatinine equation. CKD was defined by eGFR 300mg/g). According to the CKD risk map, individuals with simultaneous creatinine and ACR measurements were stratified into low, moderate, high or very high risk. RESULTS: The sample consisted of 36,651 patients in whom the same number of serum creatinine results and 19,031 ACR results were evaluated (median patients'age 72.5 [51.0-73.6] years, 51.3% male). The prevalence of CKD was 30.9% and patients with stages 3a, 3b, 4 and 5 corresponded to 15.3%, 10.2%, 3.6% and 1.7%, respectively. CKD was more frequent in older age groups: 18- 29 years (2.5%), 30-44 years (8.4%), 45-59 years (25.5%), 60-74 years (30 .7%) and ≥75 years (56.8%) (p<0.001). Patients with albuminuria categories A1, A2 and A3 were 71.5%, 22.6% and 5.9%, respectively. ACR ≥30mg/g was not associated with age: 18-29 years (23.3%), 30-44 years (23.4%), 45-69 years (26.0%), 60-74 years (28 .5%) and ≥75 years (36.9%) (p=0.671). Patients with simultaneous measurements of serum creatinine and ACR were 19,031 and their distribution in the CKD risk categories was: low (52.0%), moderate (23.8%), high (13.1%) and very high risk (11.2%). CONCLUSIONS: The results showed that CKD is present in about 30% of the patients assisted in the cardiology institute evaluated. In up to half of the patients, the risk of major outcomes such as hospitalization, need for renal replacement therapy, and death was moderate, high, or very high.

INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of death in Western countries, with heart failure being the final pathway of heart disease. Despite this, few patients are referred for Palliative Approach (PA). There is no consensus about the indication or the right time to refer patients to PA, whose main objective is to improve the patient's quality of life. OBJECTIVE: Characterize the epidemiological profile of patients with heart diseases with indication for PA in a hospital specialized in cardiology. METHODS: This is a cross-sectional study with analysis of 554 patients included for PA from Feb 2018 to Feb 2022. Frequency, median, percentage, mean, maximum and minimum value were used for statistical analysis RESULTS: The sample comprised of 554 patients (P), for PA 270( 57% ) were male, mean age 71 ±14 years, 179(37%) Catholic, 91(20%) Evangelical, With most frequent medical history of arrhythmia 242(51%), ventricular dysfunction 297(62%), Coronary artery bypass graft surgery 109 (23%) and stroke 175(15%). The most frequent clinical complains were: Dyspnea 329(59.30%), Lower limb edema 96(17.39%), diagnosis at the time of PA was renal failure 351 P (74.4%) and of these 148 (31%) needed hemodialysis, Heart failure 177(31.9%) (HF), Sepsis/Septic shock 146(26,3), stroke 113(20%). The mean ejection fraction was 40%. As for performance in activities of daily living we used the Palliative performance Scale (PPS) where 282 (71,1%) needed life support. We evaluated the prognosis with the PPI scale, 345(56.8%) with high short-term mortality. Regarding treatment, 277(58,7%) of patients with PA had CVC, 277(58.7%) received broad spectrum antibiotics, 196(41.5%) dobutamine, 138(30%) noradrenaline, 164 (34.7%) on mecanichl ventilation 130(27.5%) on hemodialysis 116(24.6%) sedated, 81 (8%) with IAP. Among these patients 295(52.9%) died during hospitalization and 126 (22%) were able to be discharged. Only 26(4.7%) did not accept the PA protocol, the most frequent site of the PA was 245(51.1%) in the ICU, followed by the ward with 227 (48%) P. CONCLUSION: In our sample we identified that patients with heart disease in PA still receive futile interventions and therapies, and the most frequent site of palliation is the ICU. This shows a later indication for PC , in patients with advanced HF and at the end of life. Strategies and institutional protocols are needed for an earlier indication, in order to promote integral care and better qualy of life.

OBJECTIVE: To determine the supply/demand ratio for procedures related to diagnosis and treatment for chronic kidney disease in the Brazilian National Health System (SUS), in the state of São Paulo, Brazil, 2019. METHODS: This was a descriptive study, using data from the SUS outpatient and hospital information systems. The numbers of medical consultations, diagnostic and chronic kidney disease monitoring tests, performed in the period, were compared with the demand estimation, obtained through ministerial guidelines. RESULTS: Exclusive SUS users were 28,791,244, and individuals with arterial hypertension and/or diabetes mellitus, 5,176,188. The number of procedures performed and the ratio between this number and the needs of the population were 389,414 consultations with nephrologists (85%); 11,540,371 serum creatinine tests (223%); 705,709 proteinuria tests (14%); 438,123 kidney ultrasounds (190%); and 1,045 kidney biopsies (36%). CONCLUSION: In the chronic kidney disease care in the SUS it could be seen simultaneous existence of lack of supply, waste and inadequate screening of important procedures.

ABSTRACT BACKGROUND: The number of nephrologists has risen slowly, compared with the prevalence of chronic kidney disease (CKD) in Brazil. Data on patients referred to nephrology outpatient clinics remains scarce. OBJECTIVE: To determine the demographic and kidney function characteristics of patients at their first appointment with a nephrologist. DESIGN AND SETTING: Retrospective study conducted at three nephrology outpatient clinics (public and private services), in São Paulo, Brazil. METHODS: From December 2019 to February 2020, we collected patient data regarding demographics, kidney function parameters and comorbidities. We then analyzed data on 394 patients who met a nephrologist for their first appointment. RESULTS: The main comorbidities were hypertension (63.7%), diabetes (33.5%) and nephrolithiasis (22.3%). Regarding CKD stages, 24.1%, 9.1%, 13.7%, 15.2%, 15.2% and 2.3% of the patients were in stages 1, 2, 3a, 3b, 4 and 5, respectively. Proteinuria was absent or mild, moderate and high in 17.3%, 15.2% and 11.7%, respectively; and 16.2% had not undergone previous investigation of serum creatinine or proteinuria (55.8%). For 17.5%, referral to a nephrologist occurred late. Patients in public services were older than those in private services (59 years versus 51 years, respectively; P = 0.001), more frequently hypertensive (69.7% versus 57.5%; P = 0.01) and reached a nephrologist later (22.4% versus 12.4%; P = 0.009). CONCLUSION: Referrals to a nephrologist were not being made using any guidelines for CKD risk and many cases could have been managed within primary care. Late referral to a nephrologist happened in one-fifth of the cases and more frequently in the public service.

Objective: To determine the supply/need ratio of procedures related to the diagnosis and care of chronic kidney disease in the SUS in the State of São Paulo, Brazil, in 2019. Methods: Descriptive study using data from SUS outpatient and hospital information systems. The number of medical consultations and diagnostic and follow-up tests for kidney disease carried out was compared with the estimates of need recommended by ministerial guidelines. Results: The exclusive SUS users were 28,791,244 and the number of individuals with hypertension and/or diabetes, 5,176,188. The number of procedures performed and the relationship between this number and the population's need was 389,414 consultations with a nephrologist (85%), 11,540,371 serum creatinine measurements (223%), 705,709 proteinuria measurements (14%), 438,123 renal ultrasounds (190%) and 1,045 kidney biopsies (36%). Conclusion: In the care of chronic kidney disease in the SUS, there is simultaneously a lack of supply, waste, and deficient tracking of important procedures.

RESUMO
Complications of chronic kidney disease (CKD) can be avoided when promptly diagnosed and treated. The objective was to describe quality indicators of CKD detection and health care in the primary care public service of a city in the State of São Paulo, Brazil. This retrospective study analyzed charts of patients who attended primary care in the public service between November 2019 and February 2020. We selected 10 health quality indicators based on their scientific relevance and availability from the medical records that could express how CKD was identified and managed in primary health care. We estimated the adequate percentage of health indicators with data from 1,066 individuals who had ≥ one risk factor for CKD: hypertension, diabetes, or > 60 years old. Among patients, 79.4% had information on serum creatinine, whereas 58.8% were investigated for proteinuria. Blood pressure data were found in 98.9% of the records. The percentage of patients with blood pressure < 140x90mmHg, glycosylated hemoglobin < 6.5% and LDL-cholesterol < 100mg/dL was 79.2%, 49.2%, and 33.3%, respectively. Renin-angiotensin system blockers were prescribed to 82.8% of the patients with hypertension and CKD. Serum potassium was measured in 35.7% for those who were using renin-angiotensin system blockers. Among those people with CKD, 16.7% had CKD assigned in the medical records as a diagnose. Among those participants at higher risk for CKD, the referral rate to a nephrologist was 31.6%. This study confirmed some missed quality indicators of CKD in primary healthcare. Our results may help administrators develop public policies that improve health care for individuals at high risk for CKD. Long-term follow-up of the health indicators we proposed here will be useful to assess the impact of policy intervention.

INTRODUCTION: Multicenter studies involving patients with acute kidney injury (AKI) associated with the disease caused by the new coronavirus (COVID-19) and treated with renal replacement therapy (RRT) in developing countries are scarce. The objectives of this study were to evaluate the demographic profile, clinical picture, risk factors for mortality, and outcomes of critically ill patients with AKI requiring dialysis (AKI-RRT) and with COVID-19 in the megalopolis of São Paulo, Brazil. METHODS: This multicenter, retrospective, observational study was conducted in the intensive care units of 13 public and private hospitals in the metropolitan region of the municipality of São Paulo. Patients hospitalized in an intensive care unit, aged ≥ 18 years, and treated with RRT due to COVID-19-associated AKI were included. RESULTS: The study group consisted of 375 patients (age 64.1 years, 68.8% male). Most (62.1%) had two or more comorbidities: 68.8%, arterial hypertension; 45.3%, diabetes; 36.3%, anemia; 30.9%, obesity; 18.7%, chronic kidney disease; 15.7%, coronary artery disease; 10.4%, heart failure; and 8.5%, chronic obstructive pulmonary disease. Death occurred in 72.5% of the study population (272 patients). Among the 103 survivors, 22.3% (23 patients) were discharged on RRT. In a multiple regression analysis, the independent factors associated with death were the number of organ dysfunctions at admission and RRT efficiency. CONCLUSION: AKI-RRT associated with COVID-19 occurred in patients with an elevated burden of comorbidities and was associated with high mortality (72.5%). The number of organ dysfunctions during hospitalization and RRT efficiency were independent factors associated with mortality. A meaningful portion of survivors was discharged while dependent on RRT (22.3%).
