Insights

Patients on hemodialysis (HD) face higher COVID-19 mortality risks. This study analyzed 141 infected HD patients in Kuwait, finding a significant mortality rate within this vulnerable group, especially those requiring intensive care.

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Epidemiology

Background:

  • Patients undergoing hemodialysis (HD) exhibit elevated susceptibility to severe COVID-19.
  • Significant variability exists in COVID-19 infection rates among HD patients.
  • Understanding mortality factors in this population is crucial for public health strategies.

Purpose of the Study:

  • To characterize COVID-19 positive hemodialysis patients in Kuwait.
  • To determine COVID-19 infection rates within the HD population.
  • To identify factors associated with mortality among HD patients with COVID-19.

Main Methods:

  • Prospective data collection from March to July 2020.
  • Analysis included demographics, comorbidities, and treatments of hospitalized HD patients with COVID-19.
  • Mortality data for HD patients with COVID-19 was systematically recorded.

Main Results:

  • 141 HD patients were admitted with COVID-19, representing 7% of the HD population and 0.2% of all COVID-19 cases.
  • Mortality rate among infected HD patients was 19% (27 deaths), accounting for 6% of total COVID-19 deaths.
  • Patients requiring continuous kidney replacement therapy (CKRT) or intensive care had higher mortality rates (34% and 65% respectively).

Conclusions:

  • Despite representing a small fraction of the total population, COVID-19 positive HD patients constitute a substantial proportion of COVID-19 cases and mortality.
  • The HD population experiences a disproportionately high COVID-19 related mortality rate.
  • Urgent attention and targeted interventions are needed for this high-risk group.

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Hemodialysis II: Procedure and Complications

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,...

Hemodialysis III: Nursing Management

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...

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
