Background
Cardiovascular disease and hypertension is highly prevalent in patients on peritoneal dialysis (PD), yet little is known about contemporary practices for blood pressure (BP) management in PD.
Methods
We conducted a national survey of US nephrologists with publicly available email addresses affiliated with 150 ACGME-accredited adult nephrology training programs. Email invitations were sent to 1786 nephrologists between January and February 2026. 100 nephrologists actively caring for patients on PD consented and completed the survey.
Results
BP management practices varied amongst nephrologists (Table 1). 68% use both home and clinic BP measurements to guide treatment decisions, while 32% rely primarily on home BP. Involvement in patient education for BP measurement technique was inconsistent. 25% had minimal or no involvement and 48% had partial involvement with staff-led education. Knowledge about patient's home BP device or cuff placement was also limited. The target systolic BP for patients varied, ranging <110 to <160 mmHg.
Conclusion
Epidemiology literature linking BP and adverse outcomes in PD is largely based on clinic BP (PMID: 41640791, 40545494), yet US nephrologists caring for PD patients rely heavily on home BP data with inconsistent oversight of home BP measurement technique. Prospective studies are needed to determine whether home BP guided management improves outcomes and to define optimal BP targets in PD.
Table 1. Summary of survey responses from nephrologists actively treating peritoneal dialysis patients (n = 100).
| Q1 | Approximately how many patients receiving PD do you care for? (n=100) | |
| 1-5 patients 6-15 patients 15-30 patients >30 patients | 31% 42% 13% 14% | |
| Q2 | When managing BP in patients receiving PD, which BP measurement setting do you primarily use to guide treatment decisions? (n=100) | |
| Home BP measurements PD clinic BP measurements Both Home and PD clinic BP measurements | 32% 0% 68% | |
| Q3A | How confident are you in the accuracy of BP measurements obtained at home (n=100) | |
| <25% 25-49% 50-74% 75-100% | 0 4 24 72 | |
| Q3B | How confident are you in the accuracy of BP measurements obtained at clinic (n=100) | |
| <25% 25-49% 50-74% 75-100% | 1 10 36 53 | |
| Q4 | How often do you recommend that your patients receiving PD measure their BP at home? (n=100) | |
| Daily Multiple times per day Several times per week Weekly Other | 61% 13% 14% 4% 8% | |
| Q5 | How involved are you in your patients | |
| Minimally or not involved – I have little or no direct involvement in education Somewhat involved – I provide some education, majority staff-led Very involved – I personally provide all or most of the education Other | 25% 48% 26% 1% | |
| Q6 | For your patients receiving PD, how often do you know which BP device (brand or cuff placement) they use at home? (n=100) | |
| Always Often Sometimes Rarely/Never | 12% 22% 31% 35% | |
| Q7 | What is your home SBP goal in patients receiving PD? (n=100) | |
| Less than 110 mmHg Less than 120 mmHg Less than 130 mmHg Less than 140 mmHg Less than 150 mmHg Less than 160 mmHg | 1% 16% 59% 23% 0% 1% | |
| Q8 | What is your clinic SBP goal in patients receiving PD? (n=68) | |
| Less than 110 mmHg Less than 120 mmHg Less than 130 mmHg Less than 140 mmHg Less than 150 mmHg Less than 160 mmHg | 0% 7% 49% 40% 3% 1% | |
