The findings of this study highlight several critical barriers that ICU nurses face in adhering to tube feeding protocols. These barriers can be broadly categorized into three main themes: the gap between theory and practice, organizational and interpersonal barriers, and resistance to change.
One of the major challenges in nursing, particularly in the context of tube feeding, is the disparity between academic knowledge and practical application. Nurses often struggle to apply theoretical knowledge in real-world settings due to various scientific, practical, and social barriers. The necessity of having up-to-date knowledge to follow the latest guidelines was frequently mentioned by nurses (17).
In Pakistan, a study discovered that the majority of intensive care nurses possessed a moderate understanding of tube feeding. The study also revealed a noteworthy correlation between the nurses' level of education and the sources from which they obtained their knowledge about tube feeding. These findings underscore the importance of continuous training for nurses, especially those working in ICUs (17). Research in Turkey demonstrated that the average knowledge score of nurses about tube feeding doubled after training (18). Similarly, a study in Australia highlighted the effectiveness of training in improving the performance of nurses in this field. These studies collectively emphasize the critical need for ongoing education and training to bridge the gap between theoretical knowledge and clinical practice (19).
ICU nurses frequently face the dual challenges of heavy workloads and limited time, which significantly hinder their ability to review and incorporate the latest evidence into their practice. This issue is well-documented in the literature, with numerous studies highlighting the demanding nature of ICU settings and the high patient-to-nurse ratios that leave little room for continuous professional development (20, 21).. For instance, Ahmed et al. found that a majority of nurses were unfamiliar with the current guidelines for enteral feeding, underscoring the gap between recommended practices and actual bedside care (22). This disconnect not only affects the quality of patient care but also highlights the urgent need for institutional support in providing time and resources for ongoing education and training. By addressing these workload and time constraints, healthcare institutions can better equip nurses to stay updated with evidence-based practices, ultimately improving patient outcomes.
Rapid changes in tube feeding guidelines have been identified as a significant barrier to adherence among ICU nurses. Studies have shown that frequent updates to these guidelines can lead to confusion and inconsistencies in practice. For instance, O'Leary-Kelley and Bawel-Brinkley highlighted that the constant evolution of nutrition support protocols often results in nurses struggling to keep up, thereby reducing adherence and increasing the risk of errors (23). Similarly, McKnight and Carter discussed how the rapid changes in hospital nutritional guidelines contribute to confusion among nursing staff, making it challenging to maintain consistent practices (24).
A positive and correct attitude towards tube feeding can significantly enhance both performance and patient care. When nurses recognize the importance and effectiveness of tube feeding, their confidence and adherence to protocols increase, leading to improved patient outcomes. This positive attitude fosters a more proactive approach to patient care, ensuring that nutritional needs are met efficiently and effectively. Recent studies corroborate this notion. For instance, Ramuada et al. found that nurses with a positive attitude towards enteral nutrition were significantly more likely to adhere to feeding protocols. This adherence not only optimizes nutritional support but also minimizes complications associated with improper feeding practices. By cultivating a positive attitude towards tube feeding, healthcare institutions can empower nurses to deliver higher quality care, ultimately enhancing patient recovery and well-being (25).
Nurses' uncertainty regarding protocols, particularly in ICU settings, can significantly impact adherence to tube feeding guidelines. This uncertainty often stems from inconsistent updates and communication about the protocols, leading to confusion and variability in practice. A study by Preiser et al. highlighted that clear and consistent guidelines are crucial for improving adherence and ensuring optimal patient care in critical care environments (26)
Adherence to routine practices remains a significant barrier to the implementation of new evidence-based guidelines among ICU nurses. Many nurses, especially those with long-standing practices, find it challenging to adapt to new methods. This resistance is often rooted in familiarity of established routines. A study by Smith et al. found that despite recognizing the benefits of evidence-based practices, nurses often struggle to integrate new protocols due to ingrained habits and the constant flux of guideline (27).
