Background: Dialysis is an intervention used chiefly to cover poorly functioning kidneys' ultrafiltration and diffusion functions. Dialysis can be performed using three major approaches: peritoneal dialysis, hemodialysis, and continuous renal replacement therapy, which have varying degrees of efficiency. We sought to compare the mortality rates among patients receiving different dialysis modalities. Study Design: Statistical Review and Meta-Analysis. Setting & Population: The investigation was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Data sources were drawn from Google Scholar, ResearchGate, PubMed (MEDLINE), Cochrane Library, and Embase databases. Eligible patients had to be ones presenting with acute or chronic kidney failure who required assistance with kidney function. Selection Criteria for Studies: The eligibility criteria included studies with participants requiring dialysis and comparing two of the three dialysis modalities that provided outcomes on mortality rates. Inclusion criteria (underlying disease, chronic or acute kidney disease, presenting signs, age categories, subject consent, etc.), the type of dialysis modalities under investigation, and the mortality rates (% per modality group). Index Texts: 'mortalities, fatalities, dialysis, hemodialysis, continuous renal replacement therapy (CRRT), Peritoneal dialysis, and comparative.' Outcomes: We sought to explore the studies' findings by comparing the mortality rates among the three broad categories of dialysis. Therefore, we aimed to compare mortality rates in CRRT vs. Hemodialysis, mortality Rates in CRRT vs. PD, and mortality rates in patients with PD vs. HD. Results: Fifteen studies were narrowed down from the study search and were placed into three categories: PD vs. CRRT (4), PD vs. HD (5), and CRRT vs. HD (6). For the three outcomes, none recorded statistically significant differences in mortality rates between the patient categories (p= 0.92, 0.009, 0.22). Conclusion: Like other interventions for patients with chronic kidney disease, dialysis is associated with detrimental effects caused by the inflammatory response and worsening progression of the condition. Mortality is a common complication among dialysis patients, independent of modality, based on the lack of statistically significant differences between the three groups. Keywords: Hemodialysis, Peritoneal dialysis, CRRT, Continuous Renal Replacement Therapy.

This study did not receive any funding

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).
