Saudi Clinical Guidelines for Peritoneal Dialysis 2014

Introduction

The Saudi Clinical Guidelines for Peritoneal Dialysis (PD) were first published in 2014 by the Saudi Center for Organ Transplantation (SCOT) and the Saudi Society of Nephrology and Transplantation (SSNT). These guidelines were developed to standardize the care of patients requiring peritoneal dialysis across the Kingdom of Saudi Arabia, providing evidence-based recommendations for healthcare professionals involved in the management of end-stage renal disease (ESRD) patients.

Patient Selection and Preparation

The guidelines emphasize careful patient selection and thorough preparation before initiating peritoneal dialysis. According to the 2014 Saudi guidelines:

Contraindications

• Absolute contraindications include untreatable mechanical defects that prevent effective PD, extensive abdominal adhesions, and lack of suitable peritoneal membrane function.
• Relative contraindications include recent abdominal surgery, inflammatory bowel disease, severe malnutrition, morbid obesity, and lack of reliable helper for patients with physical or cognitive limitations.

Patient Assessment

Before initiating PD, a comprehensive assessment should include:

• Evaluation of psychosocial status and family support
• Assessment of manual dexterity and cognitive abilities of patients and caregivers
• Appropriate nutritional assessment
• Adequate education about treatment options
• Assessment of living conditions and ability to store supplies

Catheter Placement

The guidelines recommend that:

• PD catheters should be placed by experienced surgeons or interventional nephrologists
• Pre-operative evaluation should include assessment of anatomical considerations
• Adequate time for healing (typically 2-4 weeks) should be allowed before catheter use
• Laparoscopic insertion is recommended as the preferred method for optimal placement

Peritoneal Dialysis Prescriptions

The Saudi guidelines provide recommendations for both Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD) modalities.

Initial Prescription

The initial prescription should be individualized based on:

• Patient's size and body surface area
• Residual renal function
• Peritoneal membrane characteristics
• Presence or absence of comorbid conditions
• Personal lifestyle preferences

Dose Targets

The guidelines suggest targeting a total weekly Kt/V urea of at least 1.7. This should be achieved through a combination of peritoneal clearance and residual renal function. Creatinine clearance should also be monitored, with a target of at least 50 L/week/1.73 m.

Solution Selection

Regarding dialysis solution selection:

• Icodextrin solution is recommended for patients with poor ultrafiltration
• Biocompatible solutions should be considered, especially for patients at risk of peritonitis

Lactate-buffered solutions are the standard in Saudi Arabian practice

Monitoring and Follow-up

Regular monitoring is essential to ensure optimal outcomes in patients receiving peritoneal dialysis:

Clinical Monitoring

• Regular assessment of volume status and blood pressure
• Monitoring of nutritional status using subjective global assessment (SGA)
• Evaluation of residual renal function every 3-6 months
• Regular assessment of peritoneal membrane function (PET test) annually or when clinically indicated

Laboratory Monitoring

Parameter	Frequency
Hemoglobin	Monthly
Serum albumin	Every 3 months
Calcium, phosphate, PTH	Every 3 months
Kt/V and creatinine clearance	Every 6 months
Lipid profile	Annually

Complications Management

The Saudi guidelines provide detailed recommendations for preventing and managing complications of peritoneal dialysis.

Peritonitis

For peritonitis treatment:

1. Empiric antibiotic therapy should cover both gram-positive and gram-negative organisms
2. Intraperitoneal administration of antibiotics is the preferred route
3. Cefazolin or vancomycin are recommended for gram-positive coverage
4. Ceftazidime or aminoglycoside for gram-negative coverage
5. Antifungal prophylaxis should be considered during antibiotic therapy
6. Catheter removal may be indicated in refractory cases or with fungal peritonitis

Exit-site and Tunnel Infections

The guidelines recommend:

• Daily cleansing of the catheter exit site with mild soap and water
• No routine use of topical antibiotics for prophylaxis
• Systemic or topical antibiotics based on culture results
• Catheter removal may be necessary in cases of refractory tunnel infections

Fluid Management

To ensure adequate fluid balance:

• Sodium restriction (approximately 2g/day) is recommended
• Individualized fluid restriction based on urine output and ultrafiltration
• Use of icodextrin for long dwells in patients with inadequate ultrafiltration
• Consideration of diuretics to maintain residual renal function
• Education on daily weight monitoring and recognition of fluid overload

Special Considerations for Saudi Patients

The 2014 guidelines address specific considerations relevant to the Saudi population:

Diabetes and Peritoneal Dialysis

Given the high prevalence of diabetes in Saudi Arabia:

• Tight glycemic control targets (HbA1c <7%) are recommended when safely achievable
• Using non-glucose-based solutions (icodextrin) may help reduce glucose absorption
• Careful monitoring for increased risk of infection and cardiovascular complications
• Regular screening for diabetic retinopathy and neuropathy

Religious and Cultural Considerations

The guidelines note that:

• Patients observing Ramadan may require adjustments to their dialysis schedule
• Education about performing PD procedures in a state of fasting should be provided
• Cultural sensitivity in approach to body image concerns regarding the PD catheter
• Family involvement in care planning should be encouraged when culturally appropriate

Genetic Disorders

In consideration of the higher prevalence of certain genetic disorders in the Saudi population:

• Special attention should be given to patients with hereditary renal diseases
• Family screening should be encouraged when appropriate
• Genetic counseling should be offered when hereditary conditions are identified

Training and Education

The guidelines place strong emphasis on patient and caregiver education:

Patient Training Content

Comprehensive training should include:

• Proper hand hygiene techniques
• Connection and disconnection procedures
• Exit-site care and monitoring for signs of infection
• Diet and fluid management
• Blood pressure monitoring and management
• Recognition of complications requiring medical attention
• Proper waste disposal techniques

Training Methodology

Recommendations for training approach include:

• Training should be provided by dedicated PD nurses with appropriate expertise
• A minimum of 5-7 training sessions is recommended
• Assessment of competence should be documented before independent performance
• Periodic retraining and competency assessment should be performed
• Training should be adapted to patient's educational level and cultural background

Patient Outcomes

The Saudi guidelines set benchmarks for expected outcomes in PD patients:

Expected Technical Survival

• 1-year technical survival: 80-90%
• 2-year technical survival: 70-80%
• Primary catheter failure rate: <15%

Expected Patient Survival

• 1-year patient survival: 80-90%
• 2-year patient survival: 70-80%
• 5-year patient survival: 40-50%

Quality Indicators

The guidelines recommend monitoring the following quality indicators:

• Peritonitis rate (target: <1 episode per 18 patient-months)
• Exit-site infection rate (target: <1 episode per 24 patient-months)
• Hospitalization rate
• Patient and technique survival
• Achievement of adequacy targets
• Rehabilitation status and quality of life measures

Conclusion

The 2014 Saudi Clinical Guidelines for Peritoneal Dialysis provide a comprehensive framework for the management of patients requiring peritoneal dialysis in Saudi Arabia. These guidelines, based on international evidence while addressing specific needs of the Saudi population, aim to standardize care and improve patient outcomes. Regular updates are recommended as new evidence emerges and practices evolve, with periodic review of these guidelines suggested within 5 years of initial publication. Implementation of these guidelines across healthcare centers in Saudi Arabia is encouraged to ensure consistency in the delivery of high-quality peritoneal dialysis care.
