Educating surgeons on the importance of nutrition

Precision, expertise, and attention to detail are demanded of doctors who practice the art of surgery. Surgical techniques and approaches have advanced significantly in our era, yet the impact of nutrition on patient outcomes is often overlooked. Optimized nutrition is an indispensable tool in the provision of comprehensive surgical care, affecting wound healing, immune function, and overall morbidity and mortality.[1] “Prehabilitation” for patients on surgical waiting lists has slowly gained momentum in recent years, which includes physical fitness training, improving psychological resilience, and not surprisingly optimization of nutritional status.[2] The importance of integrating education on the principles of nutrition into surgical curricula is therefore a fundamental duty we owe to the next generation of surgeons. The most conservative figure on the prevalence of malnutrition among surgical patients is 15%, but some estimate over 50%. It is associated with increased postoperative complications, longer hospital stays, and higher mortality rates.[1] In the treatment of rectal cancer, for example, the usual combination of chemotherapy, radiotherapy, and surgery results in malnutrition rates of 51% and is an independent risk factor for anastomotic leakage which is a potentially life-threatening complication.[3] Adequate nutrition perioperatively has been demonstrated as one effective approach to mitigate these risks. Understanding the role of specific nutrients in wound healing, surgeons can develop individualized nutrition plans to enhance patients’ recovery. Similarly, there must be an increased awareness that traditional fasting guidelines for surgery have been challenged, with shorter fasting durations and carbohydrate-rich drinks prior to surgery showing improved patient outcomes.[4] Enhanced recovery after surgery initiatives integrate routine nutrition education for patients, which is dependent on healthcare practitioners and surgeons having the appropriate knowledge to transfer.[5] Surgeons should have a deep understanding of traditional macronutrients (carbohydrates, proteins, and fats) and their role in providing energy, promoting tissue repair, and aiding in metabolic processes. An awareness of micronutrients (vitamins, minerals, amino acids, and trace elements), such as vitamins C and E, selenium, zinc, arginine, glutamine, and omega-3 fatty acids, is crucial as deficiencies can impair wound healing, compromise immune function, and hinder patient recovery. Accurate estimation of complex energy requirements and appropriate caloric intake are essential for developing personalized nutrition plans for patients.[6] Many surgical training programs lack comprehensive nutrition education, resulting in a deficiency of knowledge among surgeons. Challenges such as limited curriculum time, lack of faculty expertise, and a traditional focus on technical skills have impeded the integration of nutrition education into surgical training programs.[7,8] Addressing the current gaps in nutrition education is the first step toward implementing corrective strategies. For those involved in clinical training of surgeons, a multidisciplinary approach to patient care is the usual pathway to implement fundamental nutrition education. Collaboration with dieticians and nutritionists enhances knowledge exchange and promotes comprehensive care plans. Advanced educators may employ case-based learning or simulation exercises allow trainees to apply their nutrition knowledge in realistic scenarios. An active learning approach can reinforce concepts and develop critical thinking skills. Academic tutors responsible for post-graduate or higher degrees may facilitate continuous learning through online modules, mobile applications, or similar virtual platforms to provide trainees with easily accessible nutrition resources.[9] Attending conferences, participating in workshops, and engaging in self-directed learning opportunities help established surgeons stay updated with evolving nutritional guidelines and advancements. Embracing the current wave of artificial intelligence and machine learning technology will no doubt enable this. Of great significance also is the need for continued research such as high-quality randomized controlled trials – and funding opportunities for research – to strengthen the evidence base linking nutrition to surgical outcomes. The development of evidence-based algorithms, such as the regularly updated practical guidelines by the European Society for Parenteral and Enteral Nutrition,[10] requires ongoing collaboration between anesthetists, nutritionists, and allied health staff but must be spearheaded by surgeons who are ultimately responsible for their patient outcomes. Nutrition education is of paramount importance for surgeons, as it plays a significant role in surgical outcomes and patient recovery, and of even greater importance for those entrusted with surgical education. By addressing the current gaps in nutrition education and implementing comprehensive nutrition curricula, the next generation of surgeons will stand on our shoulders to optimize patient care, reduce complications, and enhance surgical outcomes.
