Who Determines PEG Feeding Rate
The PEG feeding rate is determined by the healthcare team, with the primary responsibility typically falling to the dietitian, in collaboration with the physician, nurse, and other healthcare providers involved in the patient's care. 1
Multidisciplinary Approach to PEG Feeding
- A nutritional support team (NST) typically consists of gastroenterologists, speech pathologists, and dietitians who collaborate to determine appropriate feeding regimens for patients requiring PEG feeding 2
- Studies show that when PEG discussions are initiated by nutritional support team clinicians rather than other healthcare providers, there is a significant increase in PEG uptake (56% vs 24%) 2
- The multidisciplinary team approach ensures that all aspects of the patient's condition are considered when determining feeding rates 1
Role of Different Healthcare Professionals
Dietitian's Role
- Dietitians typically calculate the patient's nutritional requirements and determine the appropriate feeding regimen including rate, volume, and formula 2
- They monitor the patient's nutritional status and make adjustments to the feeding plan as needed 3
- Dietitians ensure that the PEG feeding regime meets the patient's estimated total energy requirements (initially meeting approximately 73% of requirements, increasing to 87% prior to death in terminal patients) 2
Physician's Role
- Physicians make the initial decision regarding the need for PEG placement based on the patient's clinical condition 1
- They oversee the overall care plan and may adjust feeding rates based on the patient's medical condition 1
- Physicians are responsible for addressing complications related to PEG feeding that may require modification of the feeding rate 3
Nursing Role
- Nurses are often responsible for the day-to-day administration of PEG feeds and maintenance of the feeding tubes 4, 5
- They monitor for complications such as infection, tube blockage, or feeding intolerance that may necessitate adjustments to the feeding rate 5
- Nurses play a crucial role in providing feedback to the healthcare team about how the patient is tolerating the current feeding regimen 4
Factors Influencing PEG Feeding Rate Determination
- Patient's nutritional status including weight measurements and BMI 2
- Underlying medical condition (neurological disorders, cancer, etc.) 3
- Presence of dysphagia and ability to take any nutrition orally 1
- Patient's tolerance to the feeding (gastrointestinal symptoms, aspiration risk) 1
- Metabolic parameters to prevent refeeding syndrome, especially in malnourished patients 1
Implementation of PEG Feeding
- For patients who did not reach their nutritional requirements before PEG insertion, feeding should be initiated in a stepwise fashion with monitoring of biochemical parameters 1
- Initial PEG feeding regimens typically meet about 73% of estimated total energy requirements, with adjustments made to reach approximately 87% as tolerated 2
- Some patients require immediate full feeding via PEG, while others use it to supplement oral intake, for medication administration, or for hydration 2
Monitoring and Adjustment of Feeding Rates
- Regular assessment of nutritional status, including weight measurements, is essential for determining if feeding rates need adjustment 3, 2
- PEG feeding has been shown to stabilize weight in patients (BMI at 3 months: 22.6 ± 2.2 kg/m², at 6 months: 22.5 ± 2.0 kg/m²) 2
- Adjustments to feeding rates may be needed as the patient's condition changes, particularly in progressive neurological disorders 6
Common Pitfalls in PEG Feeding Rate Determination
- Delayed consideration of PEG placement can lead to significant weight loss (average of 11.4 ± 1.5 kg in the three months before PEG placement) 3
- Failing to adjust feeding rates in response to complications such as diarrhea, constipation, or bloating 2
- Not considering the patient's ability to supplement PEG feeding with oral intake when determining rates 1
- Inadequate monitoring of weight and nutritional parameters leading to suboptimal feeding regimens 3
