Discovering Innovative Peritoneal Dialysis Techniques Employed by UK Nephrologists
The Growing Need for Advanced Kidney Care
Chronic kidney disease (CKD) affects millions of people worldwide, with approximately 3 million individuals in the UK alone suffering from this condition. For those who progress to end-stage renal disease, dialysis becomes a necessary lifeline. Peritoneal dialysis (PD) is one of the treatment options that offers patients the flexibility of home therapy, but it requires meticulous training and innovative approaches to ensure optimal outcomes.
Innovative Training Methods: The Role of Virtual Reality
In the UK, nephrologists are embracing cutting-edge technologies to enhance patient training for peritoneal dialysis. One such innovation is the use of virtual reality (VR) training tools.

stay•safe MyTraining VR: A New Era in Patient Training
Fresenius Medical Care’s stay•safe MyTraining VR is a prime example of this innovation. This digital training tool uses immersive 3D environments to prepare patients for PD therapy at home. Here are some key benefits of this VR training:
- Additional Training Opportunities: Patients can repeat the steps of the bag exchange at their own pace, as often as needed, which helps in reinforcing the learning process.
- Support for Different Learning Styles: The tool incorporates visual, auditory, interactive, and text elements to cater to various learning styles.
- Preparation Before Hands-On Training: Patients can use VR training before or after catheter insertion, helping them be better prepared for the hands-on training that follows.
- Reduced Peritonitis Rates: Studies have shown that longer training times and starting training prior to catheter implantation are associated with lower peritonitis rates.
Predictive Analytics and AI in Dialysis Care
Beyond training, UK nephrologists are also leveraging advanced analytics and artificial intelligence (AI) to improve patient outcomes.

AI Model for Predicting Intradialytic Hypotension
Researchers at the University of Portsmouth, in collaboration with Portsmouth Hospitals University NHS Trust, have developed an AI model to predict patients at risk of intradialytic hypotension (IDH), a common and potentially fatal complication during haemodialysis.
- Data Collection and Analysis: The study collected pre-dialysis and real-time data from 10 treatment centers over two decades, involving 3,944 patients and 73,323 dialysis sessions.
- Key Predictor Variables: The AI model identified 33 variables, including systolic and diastolic blood pressures, to predict IDH events with a high degree of accuracy.
- Clinical Implications: The model can help clinicians intervene early, reducing the risk of IDH and other complications, and paving the way for personalized care.
Wearable Dialysis Devices: A Step Towards Freedom
In addition to innovative training and predictive analytics, wearable dialysis devices are another area where significant advancements are being made.
Vivance’s Viva Kompact: A Wearable Peritoneal Dialysis Device
Vivance, formerly AWAK Technologies, has completed a pre-pivotal trial of its wearable peritoneal dialysis device, Viva Kompact. This device, which received FDA breakthrough device designation in 2019, allows patients to perform dialysis independently at home.
- Trial Outcomes: The trial conducted at Singapore General Hospital involved 10 patients who used the device successfully for at least one week without any device-related serious adverse events.
- Patient Experience: The device’s performance, efficacy, and patient experience were positive, highlighting its potential to advance the possibility of dialysis anytime, anywhere.
Comparative Analysis of Dialysis Techniques
When considering the various dialysis techniques, it’s crucial to understand their differences and benefits. Here is a comparative table highlighting some key aspects of peritoneal dialysis and hemodialysis:
| Aspect | Peritoneal Dialysis (PD) | Hemodialysis (HD) |
|---|---|---|
| Location | Can be performed at home or in a clinic | Typically performed in a dialysis center |
| Frequency | Continuous or intermittent (e.g., continuous ambulatory peritoneal dialysis – CAPD) | Usually 3 times a week, 3-4 hours per session |
| Training | Requires extensive training for patients and caregivers | Less complex training required |
| Equipment | Uses a catheter and dialysis solution bags | Uses a dialysis machine and access (e.g., fistula or graft) |
| Peritonitis Risk | Higher risk of peritonitis, which can be mitigated with proper training and hygiene | Lower risk of peritonitis but higher risk of other complications like IDH |
| Lifestyle Flexibility | Offers greater flexibility and independence | Less flexible, requires regular visits to a dialysis center |
| Cost | Generally lower costs compared to HD, especially for home-based PD | Higher costs due to the need for a dialysis center and more frequent sessions |
| Clinical Outcomes | Studies show that PD can have comparable or even better outcomes in certain patient groups | HDF has been associated with better survival rates and lower hospitalization rates |
Practical Insights and Actionable Advice
For patients and healthcare providers considering peritoneal dialysis, here are some practical insights and actionable advice:
- Thorough Training: Ensure that patients receive comprehensive training, including the use of VR tools, to reduce the risk of complications like peritonitis.
- Regular Follow-Up: Regular follow-up appointments with nephrologists are crucial to monitor the patient’s condition and adjust the treatment plan as needed.
- Hygiene and Infection Control: Emphasize the importance of strict hygiene and infection control measures to minimize the risk of peritonitis.
- Lifestyle Adjustments: Encourage patients to make necessary lifestyle adjustments, such as dietary changes and regular exercise, to manage their kidney disease effectively.
- Support Systems: Establish a strong support system for patients, including family members, caregivers, and support groups, to help them cope with the emotional and physical challenges of dialysis.
