Patients with diabetes
Diabetes is the most common cause of chronic kidney disease, often causing the accelerated deterioration of kidney function and subsequent need for renal replacement therapy.
Diabetic patients have unique challenges associated with clinical management once on dialysis that are related to:
- A higher prevalence of cardiovascular comorbidity,1 peripheral vascular disease, hypoalbumineria, and hyperparathyroidism2
- Excessive accumulation of advanced glycosylated end products (AGEs)2
- HbA1c levels being falsely elevated or decreased in patients with CKD2
Given conflicting observational trial results, there is no evidence-based outcome that supports the selection of PD or HD as the treatment of choice in Stage 5 CKD patients with diabetes.3

Patients who are elderly
By 2030, 72 million Americans will be > 65 years of age (~20% of the US population). In 2021, this age group accounted for 34% of the chronic kidney disease population.1,2
There is no straight answer when it comes to choosing between HD and PD in these patients. Factors that may affect outcomes, life expectancy, and needs include:
- The number of comorbidities
- Overall day-to-day functioning (physical and mental)
- Frailty3
PD has been shown to be an acceptable modality of renal replacement therapy in elderly patients, with no observed differences in survival, technique survival, or complication rates.4 A 2018 review article that investigated comparisons between PD and HD outcomes in elderly patients found that PD is not inferior to HD when looking at technique and elderly patient survival.5

Patients who are obese
Obesity is highly prevalent among the chronic kidney disease population and has an impact on health and outcomes.1
Previously, PD was considered not a treatment of choice for obese patients. However, a variety of clinical trials demonstrate similar results in obese compared to non-obese PD patients.1,2
A 2013 study of body size and longitudinal body weight changes in Brazilian PD patients found that being overweight or obese did not increase mortality in the studied population.2

Patients who “crash start”* onto dialysis
Despite efforts to reduce unplanned dialysis starts, “crash starts” and unplanned dialysis initiation remain a challenge.
This remains a concern due to the fact that unplanned dialysis starts in North America generally result in one option: HD with a central venous catheter.2
These patients have not had the opportunity to select the modality that best suits their personal situation.
In the past decade, PD has been more widely used for patients initiating dialysis urgently or in a crash manner. The data shows:
- Survival1,3
- Catheter patency2
- Low incidence of catheter-related complications2
- High retention rates1

Patients with autosomal dominant polycystic kidney disease (ADPKD)
Concerns about a higher kidney volume reducing the effective peritoneal surface as well as increased intraperitoneal pressure are reasons that some nephrologists wonder about the applicability of PD for patients with ADPKD.1
There are a number of publications that compare results between:
- PD patients with and without ADPKD1
- ADPKD patients on HD vs. PD2
These studies show either a favourability to PD for ADPKD patients or no difference in outcomes. Use of PD in patients with ADPKD is safe and effective and should be offered to these patients.1,2

Patients with prior abdominal surgery
The belief that patients with prior abdominal surgery are not candidates for PD is not supported by clinical evidence.1,2,3
In fact, studies have shown that “scars on the abdomen and prior peritonitis do not predict the extent of adhesions and should not be used to judge eligibility for peritoneal dialysis.”1
In 2021, a study was published that assessed 171 PD patients. This study found that “prior abdominal surgical procedures do not appear to compromise peritoneal membrane function or technique survival in patients successfully started on PD.”3

Patients about to undergo abdominal surgery
Depending on a patient’s wishes, they might prefer to remain on PD rather than temporarily being transferred to HD if they require an abdominal surgery. There are a number of reports demonstrating the feasibility and process by which to maintain these patients on PD.1,2,3,4

Patients with a left-ventricular assist device (LVAD)
LVADs are increasingly being used as a bridge to transplantation or therapy in patients with end-stage heart failure (HF) refractory to conventional medical therapy. Nearly two-thirds of hospitalized patients with HF also have CKD, with 44%,14%, and 7% having CKD Stage 3, 4, and 5 respectively.1
Although there are no RCTs comparing the use of LVADs in HD and PD patients, there are data that suggest reasons for PD to be the preferred therapy for these patients:
- HD is associated with a higher incidence of bacteremia than PD.2,3
- The continuous ultrafiltration of PD creates more hemodynamic stability.2
- Residual renal function is preserved with PD.4,5

Patients with ascites
There are unique challenges in managing the cirrhotic patient with ascites population while on dialysis that include:
- Hemodynamics and the bleeding risk with HD
- Risk of early catheter leak
- Risk of spontaneous bacterial peritonitis and protein losses in the dialysate with PD1
A recent review article concluded that:
- There are no differences in outcomes between patients with and without ascites on PD vs. HD
- PD provides hemodynamic stability and facilitates better volume management compared with HD
- PD provides continuous drainage of ascites, thus mitigating the need for large-volume paracentesis2
