Summary
The number of Brazilians on chronic dialysis is rising. In 2021, COVID-19 significantly impacted mortality rates, despite high vaccination coverage among dialysis patients.
Area of Science:
- Nephrology
- Epidemiology
- Public Health
Background:
- The Brazilian Dialysis Survey (BDS) provides crucial national data on chronic dialysis patients.
- This data informs health policies for kidney failure management.
Purpose of the Study:
- To present the 2021 epidemiological data from the Brazilian Society of Nephrology's (BSN) Brazilian Dialysis Survey (BDS).
Main Methods:
- A national survey of Brazilian chronic dialysis centers was conducted using an online questionnaire.
- Data collected included patient demographics, dialysis therapy, center characteristics, and COVID-19 pandemic impact in 2021.
Main Results:
- In July 2021, 148,363 patients were on dialysis, with prevalence and incidence rates of 696 and 224 pmp, respectively.
- 94.2% of patients used hemodialysis (HD), 5.8% used peritoneal dialysis (PD), and 21% were on the transplant waiting list.
- The COVID-19 incidence rate was 1,236/10,000 patients, with a 25.5% case-fatality rate. Overall mortality was 22.3%, and COVID-19 mortality was 5.3%.
Conclusions:
- The prevalence of chronic dialysis patients in Brazil continues to increase.
- High COVID-19 vaccination rates (88.6%) were achieved, but the pandemic remained associated with increased overall mortality.

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...

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,...

197
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...

128
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...

123
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...

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
