Brief Summary

Enteral nutrition (EN) is the first choice route for nutritional support in ICU patients with a functioning digestive tract. Nevertheless, EN alone is often associated with digestive intolerance, including diarrhoea. In case of diarrhoea, EN is often reduced or discontinued, resulting in insufficient energy and protein intakes and increase complications rate in ICU patients. Diarrhoea is more frequent in ICU patients receiving EN that in those without EN or on Parenteral nutrition (PN). This difference is likely to be related to the level of EN administration needed to optimize the coverage of nutritional needs at a time when the gut has reduced absorptive capacity. Diarrhoea is suspected to have a negative economic impact on global cost, because the management of patients with diarrhoea is time-consuming for the nurses and all medical staff, it requires investigations (water and electrolytes balances, microbiology investigations, etc.) and treatments (anti-diarrhoeal drugs, antibiotics, etc). However, the economic impact of diarrhoea related to EN or the combination of EN and PN has never been evaluated in the ICU setting.

Detailed Description

Rationale: Enteral nutrition (EN) is the first choice route for nutritional support in ICU patients with a functioning digestive tract (1). Nevertheless, EN alone is often associated with digestive intolerance, including diarrhoea (2,3). In case of diarrhoea, EN is often reduced or discontinued, resulting in insufficient energy and protein intakes (4) and increase complications rate in ICU patients (5-7). Diarrhoea is more frequent in ICU patients receiving EN that in those without EN or on PN. This difference is likely to be related to the level of EN administration needed to optimize the coverage of nutritional needs at a time when the gut has reduced absorptive capacity. Diarrhoea is suspected to have a negative economic impact on global cost, because the management of patients with diarrhoea is time-consuming for the nurses and all medical staff, it requires investigations (water and electrolytes balances, microbiology investigations, etc.) and treatments (anti-diarrhoeal drugs, antibiotics, etc). However, the economic impact of diarrhoea related to EN or the combination of EN and PN has never been evaluated in the ICU setting.

Hypothesis: We made the hypothesis that the extra cost related to the combination of EN and PN prescription is compensated by the decrease in cost secondary to a reduced prevalence of EN-related diarrhoea, which means that the combination of EN and PN is cost-efficient strategy for optimal feeding in ICU patients.

It is known that:

• diarrhoea is more frequent in ICU patients with EN than in those without EN,
• the higher the EN delivery rate, the higher the risk of diarrhoea,
• the combination of EN and PN decreases the need for high EN delivery rate to fully cover the patients' nutritional needs.

It is likely that:

• diarrhoea-related care costs of EN are higher than those observed in patients receiving a combination of EN and PN,
• extra costs related to the combination of EN and PN prescription are compensated by the decrease in costs secondary to a reduced prevalence of EN-related diarrhoe,

Study objectives:

• To determine retrospectively the global prevalence of diarrhoea in all the ICU patients during a three month period.
• To determine prospectively the prevalence of diarrhoea in the ICU patients included in the "SPN study" on EN alone or EN + PN. To validate this current prevalence of diarrhoea by comparison to the retrospective prevalence rate in our ICU.
• To determine prospectively the diarrhoea-related overall costs in the patients of the "SPN study" on EN alone or EN + PN.

Study endpoints: Three categories of study endpoints will be assessed: economic, gastrointestinal tolerance, feeding protocol.

• Economic in Swiss francs:

• Nursing time for the management of diarrhoea (changes of bed-clothes and disposable nappies)and of nutritional support (time spent to prepare and administer EN and/or PN solutions, introduction and maintenance of naso-gastric tube, catheters, lines, etc)
• Medical time for prescriptions in seconds of the investigations required by the managment of diarrhoea and of the material costs: drugs (antibiotics, drugs inhibiting motility, etc.), bed-clothes, gloves, disposable nappy, EN and/or PN solutions.
• Gastrointestinal tolerance: Symptoms such as as diarrhoea, defined as liquid stools, defined as three or more liquid stools per day, for at least 1 day, and nausea, vomiting, diarrhoea, flatulence, or constipation.
• Feeding protocol: the route of feeding (EN versus PN), the type, quantities and modalities for delivering nutrition products.
• Inclusion criteria: All patients already included in the "SPN study" receiving.
• Exclusion criteria: none.
• Risk and benefit: The present study will not induce any change to the cares defined in the "SPN study" protocol.
• Additional data recorded to the "SPN study" database:

Clinical data: Diarrhoea: number and frequency of stools for the 5 intervention days (Day 3 and 8) and digestive tolerance: measurements of gastric residues according to ou on-going ICU protocol, frequency of nausea, vomiting, flatulence and constipation.

Economic data: Time measurements for physicians activities using a chronometer:Management of nutritional support, Prescription of nutritional support and micronutrients, Investigations related to the management of nutritional support: upper gastrointestinal endoscopy for the insertion of nasojejunal or nasogastric feeding tube or for the investigation of digestive intolerance, Insertion of central venous catheter, Prescription of drugs for the management of diarrhoea: antibiotics, drugs inhibiting motility, etc., Prescription of investigations for the management of diarrhoea: lower gastrointestinal endoscopy, microbiology for the analysis of stools, blood analysis (electrolytes, renal fucntion, etc)

The cost for each item will be calculated according to the cost of manpower based on mean Swiss data as previously described (8).

• Time measurements for nurses activities using a chronometer:

• Management of nutritional support

• Preparation of nutritional support: installation of pumps, connections of bottles with bags, addition of micronutrients (vitamins and trace elements) and insertion of naso-gastric tube for EN
• Monitoring: calculation and setting of flow rates
• Supervision: noting all observations regarding nutritional support in patient nursing file, changes of bottles and bags
• Management of diarrhoea

• Preparation of anti-diarrhoea drugs or antibiotics
• Nursing cares: cleaning, resetting of bed-clothes, wearing of disposable nappies, wound-dressings The cost for each item will be calculated according to the cost of manpower based on mean Swiss data as previously described (8).
• Material costs

• Drugs: antibiotics, anti-diarrhoea drugs
• Nutritional support: central venous catheters, naso-gastric tubes, cost of one day IV pump utilization, cost of nutrient solutions, additive materials
• Cleaning and disinfections: bed-clothes, gloves, caps, disposable nappy
• Statistics:

All patients included in the "SPN study" (9) will provide prospective data about the association between the type of nutritional support (EN, combination of EN and PN) and the occurrence of diarrhoea. We plan to complete this analysis by measuring the economic criteria, as described in the paragraph 7 above. These data will allow to develop an economic model to be applied to all the data acquired in the SPN study.

• Ethics This study protocol is the addendum no 1 to our existing protocol and which is in full compliance with our institution guidelines. Briefly, this extension of the protocol has been approved by the Chief of the ICU before the procedure has been initiated.
