Enteral nutrition is an essential component of medical nutrition therapy for patients who are unable to meet their nutritional requirements orally while maintaining a functioning gastrointestinal tract. In appropriate patients, enteral feeding supports the delivery of energy, protein, fluids, and other nutrients and is generally preferred to parenteral nutrition when the gastrointestinal tract can be used safely. Effective enteral nutrition, however, depends on appropriate patient assessment, suitable formula selection, an appropriate feeding method and rate, and continued clinical monitoring.

Tolerance to enteral feeding is a major practical consideration. Formula intolerance may present with nausea, vomiting, reflux, abdominal distension, diarrhea, constipation, delayed gastric emptying, or concern for aspiration. These manifestations may arise from multiple and sometimes overlapping causes, including the patient’s underlying condition, medications, feeding rate or method, gastrointestinal function, and characteristics of the selected formula. For this reason, the presence of symptoms does not necessarily indicate that the formula itself should be changed immediately.

When intolerance is not assessed and managed systematically, enteral feeding may be interrupted, reduced, or altered unnecessarily. This can compromise the delivery of prescribed energy and protein and may contribute to deterioration in nutritional status and clinical outcomes. Conversely, changing formulas without adequate assessment can increase treatment complexity and cost while failing to address the actual cause of intolerance. A structured approach to symptom assessment, monitoring, review of modifiable factors, and formula-change decisions is therefore important in clinical nutrition practice.

Despite the availability of guidance on enteral nutrition, the management of enteral nutrition intolerance is not always standardized across clinical settings or professional groups. Decisions about whether to modify the feeding rate, change the feeding method, review medications, investigate other causes of symptoms, or switch the enteral formula may differ according to professional experience, training, local practice, formula availability, and institutional protocols.

Such variation may lead to inconsistent management and uncertainty regarding the point at which a formula change is clinically justified. There is limited practice-based evidence describing how dietitians and other healthcare professionals currently assess enteral nutrition formula intolerance, which actions they take before changing a formula, which factors influence their decisions, and what barriers prevent a more standardized approach. Understanding these practice patterns is necessary to identify gaps that may be addressed through clearer protocols, targeted training, and stronger multidisciplinary collaboration.

This study will provide a structured description of current practices used by dietitians and healthcare professionals when managing enteral nutrition formula intolerance. By examining reported symptoms, pre-change management steps, decision-making factors, monitoring practices, protocol availability, and perceived barriers, the study can help clarify where practice is consistent and where important variation exists. The findings may also identify areas in which standardized guidance, professional education, or multidisciplinary coordination could strengthen enteral nutrition care.

To assess practices related to the management of enteral nutrition formula intolerance among dietitians and healthcare professionals.

This study will use a cross-sectional observational design to assess current practices related to the management of enteral nutrition formula intolerance among dietitians and healthcare professionals involved in enteral nutrition care. The design is intended to capture current professional practices, experiences, and decision-making patterns at the time of data collection without introducing an intervention or altering routine clinical practice.

The study population will consist of dietitians and healthcare professionals involved in the care of patients receiving enteral nutrition. The questionnaire will collect information on professional role and experience so that practice patterns can be described across relevant participant groups.

Data will be collected using a structured questionnaire. The questionnaire will be designed to obtain consistent information on participant characteristics, professional role, experience, commonly encountered symptoms of enteral nutrition intolerance, management practices used before formula change, formula-change decision making, monitoring methods, availability of institutional protocols, and perceived barriers to standardized care.

The main variables of interest will include reported intolerance symptoms, management actions undertaken before formula change, factors influencing the decision to change an enteral formula, monitoring practices, availability of protocols, professional role, level of experience, and perceived barriers. The questionnaire will also assess perceived needs related to protocols, training, and multidisciplinary collaboration in enteral nutrition care.

The use of a structured questionnaire will support consistent data collection across participants. Questionnaire items will be organized to align directly with the study aim and objectives, allowing the analysis to distinguish participant characteristics from reported clinical practices, decision-making factors, and perceived barriers. Responses will be reviewed for completeness before analysis, and data will be handled in a consistent format to reduce avoidable errors during data entry and analysis.

Descriptive statistics will be used to summarize participant characteristics and reported practice patterns. Categorical variables will be presented using frequencies and percentages. Continuous variables, where applicable, will be summarized using appropriate measures of central tendency and dispersion according to their distribution. Associations between professional role, experience, availability of protocols, and management practices may be assessed using appropriate statistical tests according to variable type and data distribution. A p-value of less than 0.05 will be considered statistically significant.

Where subgroup comparisons are appropriate, the analysis will focus on identifying differences in reported practices rather than inferring causality, in keeping with the cross-sectional observational design. Findings will be interpreted in relation to the study objectives and the limitations inherent in self-reported practice data.

Ethical approval will be obtained before data collection. Participation will be voluntary, and informed consent will be obtained from all participants before participation. Participants will be informed that their decision to participate or not participate will not affect their professional status or work. Data will be kept confidential, used only for research purposes, and reported in a manner that does not identify individual participants.

The study is expected to provide a clear description of how enteral nutrition formula intolerance is currently managed in clinical practice by dietitians and other healthcare professionals. It may identify commonly reported intolerance symptoms, the management steps used before formula change, factors that influence formula-change decisions, and areas of variation between professional groups or levels of experience.

The study may also identify gaps in protocol use, training, formula availability, monitoring, and multidisciplinary coordination. These findings can support the development or refinement of clearer practice guidance, targeted education, and more standardized approaches to enteral nutrition care, with the broader goal of improving the consistency and quality of nutrition support for patients receiving enteral nutrition.

By focusing on real-world professional practices, this study can generate information that is directly relevant to clinical nutrition services. Identifying the steps clinicians currently take before changing a formula, and the barriers that influence those decisions, may help institutions recognize opportunities for quality improvement. The study may also provide a basis for future work evaluating standardized intolerance-management pathways or educational interventions.

As a cross-sectional questionnaire-based study, the findings will reflect reported practices at a defined period and will not establish causal relationships between professional characteristics and management decisions. Self-reported responses may also differ from directly observed clinical practice. These considerations will be taken into account when interpreting the results and drawing conclusions.
