Unresolved issues in perioperative nutrition: A narrative review

Surgical patients are at an increased risk of negative outcomes if they are malnourished or at risk of malnutrition preoperatively. Optimisation of nutritional status should be a focus throughout the perioperative continuum to promote improved surgical outcomes. Enhanced Recovery after Surgery (ERAS) protocols are increasingly applied in the surgical setting but are not yet widespread. This narrative review focused on areas of perioperative nutrition that are perceived as controversial or are lacking in agreement. A search for available literature was conducted on 1 March 2022 and relevant high-quality articles published since 2015 were considered for inclusion. Most malnutrition screening tools are not specific to the surgical population except for the Perioperative Nutrition Screen (PONS) although more large-scale initiatives are needed to improve the prevalence of preoperative nutrition screening. Poor muscle health is common in patients with malnutrition and further exacerbates negative health outcomes indicating that prevention, detection and treatment is of high importance in this population. Although a lack of consensus remains for who should receive preoperative nutritional therapy, evidence suggests a positive impact on muscle health. Additionally, postoperative nutritional support benefits surgical outcomes, with some patients requiring enteral and/or parenteral feeding routes and showing benefit from immunonutrition. The importance of nutrition extends beyond the time in hospital and should remain a priority post-discharge. The impact of individual or personalised nutrition based on select patient characteristics remains to be further investigated. Overall, the importance of perioperative nutrition is evident in the literature despite select ongoing areas of contention.

Perioperative nutrition: Recommendations from the ESPEN expert group

BACKGROUND & AIMS

Malnutrition has been recognized as a major risk factor for adverse postoperative outcomes. The ESPEN Symposium on perioperative nutrition was held in Nottingham, UK, on 14-15 October 2018 and the aims of this document were to highlight the scientific basis for the nutritional and metabolic management of surgical patients.

METHODS

This paper represents the opinion of experts in this multidisciplinary field and those of a patient and caregiver, based on current evidence. It highlights the current state of the art.

RESULTS

Surgical patients may present with varying degrees of malnutrition, sarcopenia, cachexia, obesity and myosteatosis. Preoperative optimization can help improve outcomes. Perioperative fluid therapy should aim at keeping the patient in as near zero fluid and electrolyte balance as possible. Similarly, glycemic control is especially important in those patients with poorly controlled diabetes, with a stepwise increase in the risk of infectious complications and mortality per increasing HbA1c. Immobilization can induce a decline in basal energy expenditure, reduced insulin sensitivity, anabolic resistance to protein nutrition and muscle strength, all of which impair clinical outcomes. There is a role for pharmaconutrition, pre-, pro- and syn-biotics, with the evidence being stronger in those undergoing surgery for gastrointestinal cancer.

CONCLUSIONS

Nutritional assessment of the surgical patient together with the appropriate interventions to restore the energy deficit, avoid weight loss, preserve the gut microbiome and improve functional performance are all necessary components of the nutritional, metabolic and functional conditioning of the surgical patient.

Patient experience of health and care when undergoing colorectal surgery within the ERAS program

Background

Several studies show that the enhanced recovery after surgery (ERAS) program reduces complications postoperatively and leads to faster recovery and shorter hospital stays. However, little is known about patients’ self-reported health in an enhanced recovery context. The aim of this study was firstly to describe patient experiences of health within the concept of ERAS after colorectal (CR) surgery during a hospital stay and within 2 weeks of discharge. Secondly, to explore whether the ASA classification/co-morbidity, sex, and surgical method affect the patient’s experience of health.

Methods

Data were collected through the ERAS-HEALTH questionnaire, including two open-ended questions, and through telephone interviews postoperatively. Qualitative and quantitative analysis was used. Patients undergoing CR surgery (n = 80) were included from October 2016 to June 2018.

Results

The patients had mainly positive experiences of their hospital stay as well as most of them felt comfortable coming home. However, experienced state of health is affected by factors like surgical method and co-morbidity. Improvements were desired concerning information, food/food intake, pain management, and environment. At home, the patients experienced a lack of information about food/food intake and ostomy care. Decreased appetite and difficulties with micturition were also described. The most troublesome symptom was postoperative fatigue (POF). Analysis of the ERAS-HEALTH questionnaire showed that patients with higher co-morbidity and those who underwent open surgery have a significantly worse experience of their health compared with patients who underwent laparoscopy. However, it seems that the surgical method affects postoperative health to a greater extent than co-morbidity.

Conclusions

The patients reported many positive aspects and challenges when being cared for within the ERAS program. However, several improvements are needed to satisfy patient wishes regarding their care both in hospital and at home. Laparoscopic surgery affects patient state of health positively in several respects compared with open surgery.

Nursing Interventions in the Enhanced Recovery After Surgery®: Scoping Review

ABSTRACT Objective: To identify the Nursing interventions, described in literature, in the ERAS® program. Method: We defined a scoping review based on the recommendations of The Institute Joanna Brigs (JBI) and on research in electronic databases. We chose the studies through flow diagrams "Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)" and presented them in a chart. Results: We found 306 articles published between 2010 and 2018 and included 14 of them. The main results were: the crucial role nurses play throughout the surgical process, which begins at the preoperative nursing consultation; goes to post-operative care, such as early giving food to patients, effective management of pain or early mobilization; and ends in telephone follow-up. Conclusion: The introduction of the surgical program ERAS® may be an opportunity for nurses to play a more influential role in the surgical path, directly involving with their clients' results.

Determination of the Problems Experienced by Patients Post-Thyroidectomy

This descriptive, cross-sectional study investigated problems experienced by patients after undergoing a thyroidectomy. The study included 60 first-time, post-thyroidectomy patients diagnosed with benign thyroid disease from a university hospital's general surgery clinic in Ankara, Turkey. The data were collected in two stages: interviews with patients on the first day following surgery and postoperative follow-up telephone interviews in each of the first 4 weeks following surgery. The follow-ups revealed that patients principally experienced varying degrees of pain and difficulties in connection with work and recreation, communication, body image, and movement, for up to 4 weeks after surgery. These results showed that patients were particularly prone to problems on the first day and during the first week of the postoperative period; therefore, patients should be provided with follow-up telephone interviews to facilitate easier recovery and to help them overcome any problems experienced during the postoperative period.

Enhanced recovery, stomas and the community nurse

Enhanced recovery after surgery (ERAS) is gaining interest worldwide, to improve patient care in relation to their surgery. ERAS is a set of elements that are used to guide the multidisciplinary team in caring for patients before, during and after surgery. This ERAS care challenges traditional care, but it is research based and has been shown in many settings to be effective. There are no specific recommendations for post-discharge care in the remit of the community nurse, but this is extracted from the published literature and personal experience of enhanced recovery. This article will explore issues related to ERAS and how this may affect the community nurse. Issues surrounding stoma care will be explored, including how the community nurse can aid the care of this patient group.

Enhanced recovery and nurse-led telephone follow-up post surgery

AIM

Nurse-led telephone follow-up was undertaken for patients after major colorectal surgery on the enhanced recovery programme following their discharge, with the aim of ensuring they were provided with adequate advice and information to enable their recovery at home.

METHODOLOGY

A total of 200 patients were prospectively called within 4 weeks of discharge home from hospital by the enhanced recovery nurse.

RESULTS

Diet was generally tolerated and mobility was continued at home. Many of the patients had seen a health professional since their discharge home for issues such as wound care or stoma review. Readmission rates were low and most concerns that patients reported were addressed during the telephone call.

DISCUSSION

It is reassuring that the majority of patients were coping well and many of the concerns reported were simply addressed over the telephone with advice. After the first 100 patients were telephoned, improvements were made to the discharge advice provided to the second 100 patients. The responses suggest that there were less community nurse visits in the second half of the patient cohort and this may be associated with changes made to discharge advice.

CONCLUSION

Patients continue to recover well once discharged home following colorectal surgery on the enhanced recovery pathway. Nurse-led telephone follow-up may be a suitable method for short-term follow-up and, potentially, it is also suitable for long-term follow-up of select groups of cancer patients.
