Implementing and sustaining an evidence-based nutrition service in a haematology unit for autologous stem cell transplant patients

Core elements and principles of nutrition models of care for people with cancer: A scoping review

BACKGROUND AND AIMS

The development and implementation of evidence-based cancer nutrition models of care into clinical practice is challenging and pragmatic guidance is lacking. This scoping review aimed to identify the core elements and principles of nutrition models of care for people with cancer.

METHODS

MEDLINE Complete, CINAHL and Embase were systematically searched between 1 January 2003-8 November 2023. Studies were eligible for inclusion and data extraction if they reported on the implementation or evaluation of a nutrition model of care for adults with any cancer diagnosis. The protocol was prospectively registered on Open Science Framework (https://doi.org/10.17605/OSF.IO/RQVHJ) on 7 November 2023.

RESULTS

The search identified 4599 papers, 28 studies met inclusion criteria. Studies were primarily conducted in Australia (71.4 %), within a hospital (96.4 %), metropolitan setting (89.3 %) and with various cancer diagnoses. Most studies described a nutrition screening process and 50 % used a valid and reliable assessment tool. Studies described provision of direct care by the dietitian (n = 26), primarily conducted in the outpatient setting (n = 26) and lesser in the inpatient setting (n = 12), and frequently face-to-face (n = 25) [phone (n = 14), telehealth (n = 3)]. Ten core elements were identified that underpinned the models of care including: timely care driven by a care pathway, protocol or clinic (100.0 %); nutrition expertise and leadership (100.0 %); flexible and integrated (100.0 %); with multi-directional communication (96.4 %); accessible (92.9 %); stratified by risk (89.3 %); multidisciplinary engagement (85.7 %); across different care time-points and settings (85.7 %); supported by training/education (50.0 %) and data integration (25.0 %).

CONCLUSIONS

Nutrition expert-led cancer nutrition models of care literature was primarily limited to metropolitan, hospital settings and many lacked valid nutrition assessment tools. Ten core elements were identified that underpinned nutrition care, with the most utilised being: timely care driven by a care pathway, protocol or clinic; nutrition expert-led; flexible and integrated; with multi-directional communication; accessible; and stratified by risk. There is great potential for an evidence-based model of nutrition care to improve the implementation and embedding of high-quality nutrition elements into the cancer pathway.

Prehabilitation to improve function after autologous stem cell transplantation: A pilot randomized controlled trial (PIRATE)

PURPOSE

Exercise and nutrition interventions are not part of routine care for those undergoing autologous stem cell transplant (autoSCT). We aimed to explore estimates of effect, safety and feasibility of multidisciplinary prehabilitation for improving physical capacity after autoSCT.

METHODS

This single-blinded, parallel, two-armed pilot randomized trial included adults receiving autoSCT. Participants were randomized to twice-weekly, supervised, tailored exercise and fortnightly telephone-based nutrition education, for up to 8-weeks prior to autoSCT (n = 11) or usual care (n = 11). Blinded assessments occurred at baseline (T0), pre-transplant (T1), and 4-weeks post-transplant (T2). The primary outcome was physical capacity (6-min walk test). Secondary measures included recruitment rate, adverse events, exercise adherence, physical status, nutritional status, health-related quality of life, and health service outcomes.

RESULTS

Positive estimates of effect for walking capacity in favour of the experimental group were demonstrated at T2 (MD + 141 m, 95% CI 24 to 257 m). There was high recruitment (81%) and adherence and no major adverse events. At T2 there were large estimates of effect favoring the experimental group for higher bodyweight, and less dyspnea and gastrointenstinal symptoms. There were no between-group differences in other outcomes.

CONCLUSION

Prehabilitation is safe, feasible and may improve walking capacity after autoSCT. Findings support a future fully-scaled trial of prehabilitation for autoSCT.

Nutritional aspects in autoimmune diseases undergoing hematopoietic stem cell transplantation: overview and recommendations on behalf of the EBMT ADWP and Nurses Group

Autoimmune diseases (ADs) represent a heterogeneous group of conditions affecting 5-10% of the global population. In recent decades, hematopoietic stem cell transplant (HSCT), mainly autologous, has been successfully adopted to treat patients affected by severe/refractory ADs. In this context malnutrition has a detrimental impact on relapse, mortality, infection rate, engraftment, long-term survival, and prolongation of hospitalization. However, in this population, the management of nutrition should be improved since nutritional assessment is partially performed in routine clinical practice. A panel of nurses and physicians from the European Society for Blood and Marrow Transplantation (EBMT) reviewed all available evidence based on current literature and expert practices from centers with extensive experience in HSCT for ADs, on the nutritional management of ADs patients during HSCT procedure. In this context, adequate nutritional status predicts a better response to treatment and improves quality of life. Herein, a systematic and comprehensive monitoring of nutritional status before, during and after HSCT, with adequate nutritional support in the case of ADs patients, in addition to assessing the dietary requirements associated with HSCT has been covered. Moreover, given the singularity of each AD, the underlying disease should be considered for an appropriate approach. The management and evaluation of nutritional status must be carried out by a multidisciplinary team to assess the needs, monitor the effectiveness of each intervention, and prevent complications, especially in complex situations as patients affected by ADs.

Medical nutrition therapy during intensive remission-induction treatment and hematopoietic stem cell transplantation in acute myeloid leukemia patients: Hematologists' experiences and perspectives

BACKGROUND & AIMS

The European Societies for Clinical Nutrition and Metabolism (ESPEN) and Blood and Marrow Transplantation (EBMT) recommend enteral nutrition (EN) as the first-choice medical nutrition therapy in acute myeloid leukemia (AML) patients undergoing intensive treatments, including high-dose remission-induction chemotherapy and hematopoietic stem cell transplantation (HSCT). However, parenteral nutrition (PN) remains the preferred method of nutrition support in current clinical practice. The aim of this qualitative study was to gain insight into hematologists' experiences and perspectives regarding the choice and ESPEN/EBMT recommendations on EN versus PN.

METHODS

Online semi-structured interviews were conducted with one hematologist from each of the 21 hospitals offering intensive AML treatments in the Netherlands, using Microsoft Teams. Interviews were audio-recorded, transcribed verbatim and thematically analyzed using Atlas. ti. One hundred nineteen hematologists working in the same hospitals were invited to complete a short online questionnaire survey (SurveyMonkey®) regarding their knowledge and opinion on the ESPEN/EBMT guidelines recommending EN over PN during intensive AML treatments. The results of this survey are presented in a descriptive way.

RESULTS

Fifty-nine hematologists participated in this study (42% overall response rate), of which 21 in the semi-structured interviews (response rate 100%) and 38 in the online survey (response rate 32%). Hematologists considered medical nutrition therapy important for prevention and treatment of malnutrition and associated adverse outcomes in AML patients undergoing intensive remission-induction treatment and HSCT. However, opposed to the ESPEN/EBMT guidelines, the vast majority of hematologists were hesitant or reluctant to use EN instead of PN as the first-choice medical nutrition therapy in these patients. The most frequently cited barriers to use EN were the expected low feasibility and tolerance of EN, feeding tube-related discomfort and bleeding risk, and patient refusal. Other barriers to follow the guidelines on EN were related to personal factors, including hematologists' knowledge (lack of awareness and familiarity) and attitude (lack of agreement, outcome expectancy, experience, success, motivation, and learning culture), guideline-related factors (lack of evidence and applicability), and external factors (lack of collaboration and resources). Facilitators included strategies for nutrition education and dissemination of nutritional guidelines, interprofessional and patient collaboration, availability of feeding tubes that can be inserted without endoscopy and stronger scientific evidence.

CONCLUSIONS

Hematologists recognized the importance of medical nutrition therapy for reducing malnutrition and related negative outcomes during intensive AML treatments. However, contrary to the ESPEN/EBMT guidelines, they preferred PN instead of EN as the medical nutrition therapy of first choice. To reduce compliance barriers, interventions should focus on improving hematologists' knowledge of medical nutrition therapy and dietary guidelines, enhancing success rates of EN by adequately triaging patients eligible for EN and inserting duodenal feeding tubes using an electromagnetic sensing device without endoscopy, developing decision aids and multidisciplinary guidelines and care pathways. Furthermore, future trials should focus on the feasibility and benefits of EN versus PN both during remission-induction treatment and HSCT.

The Critical Exploration into Current Evidence behind the Role of the Nutritional Support in Adult Patients Who Undergo Haematogenic Stem Cell Transplantation

Haematopoietic stem cell transplantation (HSCT) is a treatment option for many haematological conditions in patients of all ages. Nutritional support is important at each stage of treatment, but particular nutritional needs and dictated support occur during the preparatory (conditioning regimen) and post-transplant periods. Patients may require nutritional treatment by the enteral or parenteral route. The quantitative and qualitative composition of meals may change. Vitamin requirements, including vitamin D and vitamin C, might also be different. An adequately composed diet, adapted to the needs of the patient, may influence the occurrence of complications such as graft-versus-host disease (GvHD), gastrointestinal disorders, infections, and reduced survival time. Haematological diseases as well as transplantation can negatively affect the intestinal flora, with negative consequences in the form of mucosal inflammation and disorders of a functional nature. Currently, aspects related to nutrition are crucial in the care of patients after HSCT, and numerous studies, including randomized trials on these aspects, are being conducted. This study serves the critical analysis of current scientific evidence regarding nutritional support for patients after HSCT.

Prehabilitation to improve outcomes afteR Autologous sTem cEll transplantation (PIRATE): A pilot randomised controlled trial protocol

BACKGROUND

Autologous stem cell transplant is a common procedure for people with haematological malignancies. While effective at improving survival, autologous stem cell transplant recipients may have a lengthy hospital admission and experience debilitating side-effects such as fatigue, pain and deconditioning that may prolong recovery. Prehabilitation comprising exercise and nutrition intervention before stem cell transplant aims to optimise physical capacity before the procedure to enhance functional recovery after transplant. However, few studies have evaluated prehabilitation in this setting. We aim to explore preliminary efficacy of improving physical capacity of prehabilitation for people undergoing autologous stem cell transplant.

METHODS

The PIRATE study is a single-blinded, parallel two-armed pilot randomised trial of multidisciplinary prehabilitation delivered prior to autologous stem cell transplantation. Twenty-two patients with haematological malignancy waitlisted for transplant will be recruited from a tertiary haematology unit. The intervention will include up to 8 weeks of twice-weekly, supervised tailored exercise and fortnightly nutrition education delivered via phone, in the lead up to autologous stem cell transplant. Blinded assessments will be completed at week 13, approximately 4 weeks after transplant and health service measures collected at week 25 approximately 12 weeks after transplant. The primary outcome is to assess changes in physical capacity using the 6-minute walk test. Secondary measures are time to engraftment, C-reactive protein, physical activity (accelerometer), grip strength, health-related quality of life (EORTC QLQ-C30 and HDC29 supplement), self-efficacy and recording of adverse events. Health service data including hospital length of stay, hospital readmissions, emergency department presentations and urgent symptom clinic presentation at will also be recorded.

DISCUSSION

This trial will inform design of a future definitive randomised controlled trial and implementation of prehabilitation for people receiving autologous stem cell transplant by providing data on efficacy and safety.

TRIAL REGISTRATION

The PIRATE Trial has been approved by the Eastern Health Human Research Ethics Committee (E20/003/61055) and is funded by the Eastern Health Foundation. This trial is registered with the Australian New Zealand Clinical Trials Registry ACTRN12620000496910. Registered April 20, 2020.

Implementation of a standardised perioperative nutrition care pathway in upper gastrointestinal cancer surgery: a multi-site pilot study

BACKGROUND

Perioperative nutrition support is recommended for patients undergoing upper gastrointestinal (UGI) cancer surgery; however, limited evidence exists regarding implementation of a nutrition care pathway in clinical practice. The aims of this pilot study were to determine if implementation of a standardised perioperative nutrition pathway for patients undergoing UGI cancer surgery improves access to dietetics care, and to evaluate study feasibility, fidelity, resource requirements and effect on clinical outcomes.

METHODS

Patients with newly diagnosed UGI cancer from four major metropolitan hospitals in Melbourne, planned for curative intent surgery, were included in the prospective pilot study (n=35), with historical controls (n=35) as standard care. Outcomes were dietetics care (dietetics contacts) nutritional status; hand grip strength; weight change; preoperative hospital admissions; complications and length of stay; recruitment feasibility; fidelity and adherence; and, resource requirements. Continuous data were analysed using independent samples t-test accounting for unequal variances or Mann-Whitney U test. Dichotomous data were analysed using Fisher's exact test.

RESULTS

The percentage of participants receiving preoperative dietetic intervention increased from 55% to 100% (p<0.001). Mean and standard deviation (SD) dietetics contacts increased from 2.2 (3.7) to 5.9 (3.9) (p<0.001). Non-statistically significant decreases in preoperative nutrition-related hospital admissions, and surgical complications were demonstrated in patients who underwent neoadjuvant therapy. Recruitment rate was 81%, and adherence to the nutrition pathway was high (>70% for all stages of the pathway). The mean estimated resource requirement for the preoperative period was 3.7 (2.8) hours per patient.

CONCLUSION

Implementation of this standardised nutrition pathway resulted in improved access to dietetics care. Recruitment feasibility and high fidelity to the intervention suggest that a larger study would be viable. This article is protected by copyright. All rights reserved.

Health service nutrition practices and associations with clinical outcomes in patients undergoing resection for upper gastrointestinal cancer: results from the multi-centre NOURISH point prevalence study

BACKGROUND

This study aimed to investigate health service nutrition practices of sites providing care to patients undergoing surgery for upper gastrointestinal (UGI) cancer within Australia, including the provision of perioperative nutrition support services and outpatient clinics, and the use of evidence-based nutrition care pathways/protocols. Secondary aims were to investigate associations between the use of a nutrition care pathway/protocol and patient outcomes.

METHODS

Principal investigator dietitians for the sites (n=27) participating in the NOURISH point prevalence study participated in a purpose-built site-specific survey regarding perioperative nutrition practices and protocols. Data from the 200 patients who participated in the study (including malnutrition prevalence, preoperative weight loss and receipt of dietetics intervention, intraoperative feeding tube insertions, provision of nutrition support day one post surgery, length of stay and complications) were investigated using multivariate analysis to determine associations with the sites' use of a nutrition care pathway/protocol.

RESULTS

The majority of sites (>92%) reported having dietetics services available in chemotherapy/radiotherapy. Eighty-five percent of sites reported having some form of outpatient clinic service; however, a routine service was only available at 26% of sites preoperatively and 37% postoperatively. Most preoperative services were embedded into surgical/oncology clinics (70%); however, this was reported for only 44% of postoperative clinics. Only 44% had a nutrition care pathway/protocol in place. The use of a nutrition care pathway/protocol was associated with lower rates of malnutrition, and higher rates of preoperative dietetics intervention, intraoperative feeding tube insertions and ESPEN guideline compliant care day one post surgery.

CONCLUSIONS

The results of this study demonstrate varied perioperative outpatient nutrition services in this high-risk patient group. The use of nutrition care pathways and protocols was associated with improved patient outcomes. This article is protected by copyright. All rights reserved.

Implementing a standardised perioperative nutrition care pathway in upper gastrointestinal cancer surgery: a mixed-methods analysis of implementation using the Consolidated Framework for Implementation Research

Background

Implementation studies of complex interventions such as nutrition care pathways are important to health services research, as they support translation of research into practice. There is limited research regarding implementation of a nutrition care pathway in an upper gastrointestinal (UGI) cancer population. The aim of this study was to comprehensively evaluate the implementation process of a perioperative nutrition care pathway in UGI cancer surgery using The Consolidated Framework for Implementation Research (CFIR).

Methods

This was a mixed methods implementation study conducted during a pilot study of a standardised nutrition care pathway across four major hospitals between September 2018 to August 2019. Outcome measures included five focus groups among study dietitians (n = 4–8 per group), and quantitative satisfaction surveys from multi-disciplinary team (MDT) members (n = 14) and patients (n = 18). Focus group responses were analysed thematically using the CFIR constructs, which were used as a priori codes. Survey responses were summarised using means and standard deviations. A convergent parallel mixed methods approach according to CFIR domains and constructs was used to integrate qualitative and quantitative data.

Results

Qualitative data demonstrated that dietitian perceptions primarily aligned with five CFIR constructs (networks and communications, structural characteristics, adaptability, compatibility and patient needs/resources), indicating a complex clinical and implementation environment. Challenges to implementation mostly related to adapting the pathway, and the compatibility of nutrition coordination to existing aspects of care within each setting. Identified benefits from dietitian qualitative data and MDT survey responses included increased engagement between the dietitian and MDT, and a more proactive approach to nutrition care. Patients were highly satisfied with the service, with the majority of survey items being rated highly (≥4 of a possible 5 points).

Conclusions

The nutrition care pathway was perceived to be beneficial by key stakeholders. Based on the findings, sustainability and compliance to this model of care may be achieved with improved systems level coordination and communication.

Awareness and perceptions of nutrition support in upper gastrointestinal cancer surgery: A national survey of multidisciplinary clinicians

BACKGROUND

Patients undergoing surgery for upper gastrointestinal (UGI) cancer are at high risk of malnutrition, and a multidisciplinary approach to management is recommended. This study aimed to determine practices, awareness and perceptions of multi-disciplinary clinicians with regards to malnutrition screening and provision of nutrition support.

METHODS

A national survey of dietitians, surgeons, oncologists and nurses was conducted using a 30-item online REDCap survey, including questions regarding self-reported malnutrition screening/nutrition support practices, awareness and perceptions, and barriers and enablers. The survey was distributed via professional organisations/networks between 1st September and 30th November 2020. Results are presented as counts and percentages.

RESULTS

There were 130 participants (56% dietitians, 25% surgeons, 11% nurses, 8% oncologists). The majority reported that dietitians and nurses performed malnutrition screening, and dietitians and surgeons prescribed nutrition support. Most participants reported that their health service had dietetics support available overall (98%), however only 41% reported having an outpatient service. Participants (>90%) demonstrated very high awareness of the significance of malnutrition and the importance of early nutrition support. Participants mostly perceived dietitians, nurses and surgeons to be responsible for malnutrition screening, whilst responsibility of prescription of nutrition support was mostly dietitians and surgeons. There were a higher number of barriers for the outpatient setting (48%) than the inpatient setting (38%).

CONCLUSIONS

Participants identified a high awareness of the importance of identification and treatment of malnutrition in UGI cancer surgery. However reported practices varied and appear to be lacking in the outpatient setting, with significant barriers identified to providing optimal nutrition care.

Implementation of a Multidisciplinary Allied Health Optimisation Clinic for Cancer Patients with Complex Needs

This study examined the feasibility of implementing a multidisciplinary allied health model of care (MOC) for cancer patients with complex needs. The MOC in this retrospective study provided up to eight weeks of nutritional counselling, exercise prescription, fatigue management and psychological support. Implementation outcomes (acceptability, adoption, fidelity and appropriateness) were evaluated using nine patient interviews, and operational data and medical records of 185 patients referred between August 2017 and December 2018. Adoption, including intention to try and uptake, were acceptable: 88% of referred patients agreed to screening and 71% of eligible patients agreed to clinic participation. Fidelity was mixed, secondary to inpatient admissions and disease progression interrupting patient participation. Clinician compliance with outcome assessment was variable at program commencement (dietetic, 95%; physiotherapy, 91%; occupational therapy, 33%; quality of life, 23%) and low at program completion (dietetic, 32%; physiotherapy, 13%; occupational therapy, 10%; quality of life, 11%) mainly due to non-attendance. Patient interviews revealed high satisfaction and perceived appropriateness. Adoption of the optimisation clinic was acceptable. Interview responses suggest patients feel the clinic is both acceptable and appropriate. This indicates a multidisciplinary model is an important aspect of comprehensive, timely and effective care. However, fidelity was low, secondary to the complexities of the patient cohort.

Awareness, perceptions and practices regarding cancer-related malnutrition and sarcopenia: a survey of cancer clinicians

PURPOSE

Cancer-related malnutrition and sarcopenia have severe negative consequences including reduced survival and reduced ability to complete treatment. This study aimed to determine the awareness, perceptions and practices of Australian oncology clinicians regarding malnutrition and sarcopenia in people with cancer.

METHODS

A national cross-sectional survey of Australian cancer clinicians was undertaken between November 2018 and January 2019. The 30-item online purpose-designed survey was circulated through professional organizations and health services.

RESULTS

The 111 participants represented dietetic (38%), nursing (34%), medical (14%) and other allied health (14%) clinicians. Overall, 86% and 88% clinicians were aware of accepted definitions of malnutrition and sarcopenia, respectively. Perception of responsibility for identification of these conditions varied across participants, although 93% agreed this was a component of their role. However, 21% and 43% of clinicians had limited or no confidence in their ability to identify malnutrition and sarcopenia, respectively. Common barriers to the identification and management of malnutrition were access to the tools or skills required and a lack of services to manage malnourished patients. Common barriers to identification of sarcopenia were lack of confidence and lack of services to manage sarcopenic patients. Enablers for identification and management of malnutrition and sarcopenia were variable; however, training and protocols for management ranked highly.

CONCLUSION

While awareness of the importance of cancer-related malnutrition and sarcopenia are high, participants identified substantial barriers to delivering optimal nutrition care. Guidance at a national level is recommended to strengthen the approach to management of cancer-related malnutrition and sarcopenia.
