Summary
The number of patients on chronic dialysis in Brazil is increasing, with hemodialysis being the predominant treatment. The COVID-19 pandemic significantly impacted mortality rates among dialysis patients in 2020.
Area of Science:
- Nephrology
- Epidemiology
- Public Health
Background:
- National data on chronic dialysis are crucial for developing effective health policies.
- Understanding treatment trends and patient demographics is essential for improving care.
Purpose of the Study:
- To present epidemiological data from the 2020 Brazilian Dialysis Survey.
- To analyze the clinical and epidemiological aspects of chronic dialysis patients in Brazil.
- To assess the impact of the COVID-19 pandemic on dialysis treatment.
Main Methods:
- A nationwide survey of Brazilian chronic dialysis centers was conducted.
- An online questionnaire collected data on patient demographics, dialysis therapy, unit characteristics, and COVID-19 impact.
- Data from 235 responding centers (28% of total) were analyzed for July 2020.
Main Results:
- An estimated 144,779 patients were on dialysis, with prevalence and incidence rates of 684 and 209 per million population, respectively.
- Hemodialysis (HD) was used by 92.6% of patients, while 7.4% used peritoneal dialysis (PD). 23% were on the transplant waiting list.
- The COVID-19 incidence rate was 684/10,000 dialysis patients, with a 25.7% lethality rate. Overall mortality was 24.5%.
Conclusions:
- The prevalence of chronic dialysis patients continues to rise in Brazil.
- Low utilization of peritoneal dialysis and increased use of central venous catheters for hemodialysis were observed.
- The COVID-19 pandemic exacerbated the overall mortality rate among dialysis patients.

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

169
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

376
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

250
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

164
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

370
Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...
