Dietitian-led micronutrient management in a public bariatric surgery outpatient clinic.

AIMS: This study aimed to explore the multidisciplinary team attitudes and knowledge of bariatric surgery micronutrient management (pre- and postoperative care) and to evaluate the implementation of an extended-scope of practice dietitian-led model of care for micronutrient monitoring and management. METHODS: A mixed method study design included quantitative evaluation of micronutrient testing practices and deficiency rates. Qualitative reflexive thematic analysis was used to interpret multidisciplinary experience with micronutrient monitoring in a traditional and dietitian-led model of care. In addition, deductive analysis used normalisation process theory mapping of multidisciplinary experience with the implementation of the dietitian-led model of care. RESULTS: In the traditional model, a lack of quality evidence to guide micronutrient management, and a tension in trust between surgeons and patients related to adherence to micronutrient prescriptions were described as challenges in current practice. The dietitian-led model was seen to overcome some of these challenges, increasing collaborative, and coordinated, consistent and personalised patient care that led to increased testing for and detection of micronutrient deficiencies. Barriers to sustainability of the dietitian-led model included a lack of workforce succession planning, and no clearly defined delegation for some aspects of care. CONCLUSION: An extended scope dietitian-led model of care for micronutrient management after bariatric surgery improves clinical care. Challenges such as succession planning must be considered in design of extended scope services.

Monitoring for micronutrient deficiency after bariatric surgery-what is the risk?

BACKGROUND: Bariatric surgery may increase the risk of micronutrient deficiencies; however, confounders including preoperative deficiency, supplementation and inflammation are rarely considered. OBJECTIVE: To examine the impact of bariatric surgeries, supplementation and inflammation on micronutrient deficiency. SETTING: Two public hospitals, Australia. METHODS: Participants were recruited to an observational study monitoring biochemical micronutrient outcomes, supplementation dose, inflammation and glycaemic control, pre-operatively and at 1-3, 6 and 12 months after gastric bypass (GB; Roux-en-Y Gastric Bypass and Single Anastomosis Gastric Bypass; N = 66) or sleeve gastrectomy (SG; N = 144). Participant retention at 12 months was 81%. RESULTS: Pre-operative micronutrient deficiency was common, for vitamin D (29-30%), iron (13-22%) and selenium (39% GB cohort). Supplement intake increased after surgery; however, dose was <50% of target for most nutrients. After SG, folate was vulnerable to deficiency at 6 months (OR 13 [95% CI 2, 84]; p = 0.007), with folic acid supplementation being independently associated with reduced risk. Within 1-3 months of GB, three nutrients had higher deficiency rates compared to pre-operative levels; vitamin B1 (21% vs. 6%, p < 0.01), vitamin A (21% vs. 3%, p < 0.01) and selenium (59% vs. 39%, p < 0.05). Vitamin B1 deficiency was independently associated with surgery and inflammation, selenium deficiency with improved glycaemic control after surgery and inflammation, whilst vitamin A deficiency was associated with inflammation only. CONCLUSION: In the setting of prophylactic post-surgical micronutrient prescription, few nutrients are at risk of de novo deficiency. Although micronutrient supplementation and monitoring remains important, rationalising high-frequency biochemical testing protocols in the first year after surgery may be warranted.

Patient experiences with micronutrient and overall nutrition management after bariatric surgery: identifying facilitators and barriers to implementing care.

BACKGROUND: Adherence to perioperative guideline recommendations for prophylactic supplementation and regular biochemical monitoring is suboptimal. However, little is known about the patient perspective on this postoperative challenge. OBJECTIVES: To qualitatively explore patient experiences of postoperative micronutrient management and identify patient-reported barriers and facilitators to the provision of nutrition care. SETTING: Two tertiary public hospitals in Queensland, Australia. METHODS: Semi-structured interviews were conducted with 31 participants 12 months after bariatric surgery. Inductive analysis of interview transcripts was performed using applied thematic analysis, and deductive analysis was performed by aligning interview themes against the Theoretical Domains Framework and the Capability, Motivation, and Opportunity Behavior Change Wheel Framework. RESULTS: Participants' perceptions of engagement with the bariatric surgery multidisciplinary team greatly influenced their experience with overall nutrition care, including but not exclusive to micronutrient care. At times, this engagement negatively impacted patients' experiences with their nutrition care and related to varied acceptance of healthcare advice from the team or, at times, an unmet desire for person-centered communication styles. Engaging person-centered care techniques had a positive influence on patient experience with micronutrient and overall nutrition care. Micronutrient management (taking supplements and having regular blood tests) was broadly accepted and enabled by the presence of established medication and blood test routines preoperatively. However, challenges did exist and were practical in nature. Incorporating education on habit-forming techniques was identified as a facilitator to assist with micronutrient management. CONCLUSION: Although participants mostly accept embedding micronutrient management into their life, developing interventions that focus on habit-forming skills and that enable multidisciplinary teams to provide person-centered care is recommended to enhance care after surgery.

Iron, Vitamin B12, Folate and Copper Deficiency After Bariatric Surgery and the Impact on Anaemia: a Systematic Review.

Bariatric surgery may increase the risk of iron, vitamin B12, folate and copper deficiencies, which can cause anaemia. This review aims to critique the evidence on the prevalence of these nutritional deficiencies and the impact on anaemia in the first 12 months after surgery. PRISMA and MOOSE frameworks, the NHMRC evidence hierarchy and The Academy of Nutrition and Dietetics bias tool were used to systematically critique current literature. Seventeen studies reported on deficiency prevalence with the majority being of low quality. Important confounders to serum micronutrient levels were not adequately considered. Results on the prevalence of nutritional anaemias were also lacking. Further investigation into the prevalence of iron, vitamin B12, folate and copper deficiency and its impact on anaemia in bariatric surgery is needed.

Patient and carer experience of nutrition care throughout treatment for head and neck cancer: a systematic qualitative review and thematic synthesis.

Nutrition care plays a critical role in the provision of best practice care to head and neck cancer (HNC) patients, with carers playing an important role in supporting patients to maintain nutrition intake. This qualitative systematic review investigated patient and carer experience of nutrition care throughout and beyond HNC treatment. Five databases were systematically searched for qualitative studies reporting on patient and carer experience of nutrition care throughout HNC. Twenty-five studies including 435 patients and 46 carers were identified, revealing three themes: information and support in the healthcare setting, enteral feeding challenges and management, and life outside hospital. Findings highlight the importance of providing individualised person-centred nutrition care to patients with HNC and their carers. Further qualitative research is needed to inform healthcare professionals about the needs of patients and carers to provide appropriate support throughout the treatment trajectory across and between different treatment modalities.

Micronutrient management following bariatric surgery: the role of the dietitian in the postoperative period.

Bariatric surgery is increasingly being utilized to manage obesity and obesity related comorbidities, but may lead to the development of micronutrient deficiencies postoperatively. The anatomical, physiological, nutritional and behavioral reasons for micronutrient vulnerabilities are reviewed, along with recommendations for routine monitoring and replacement following surgery. The role the dietitian and their contribution in the postoperative identification, prevention and management of micronutrient vulnerabilities in bariatric patients is described. Specific considerations such as the nutritional and dietetic management of pregnant and lactating women post-bariatric surgery is also discussed.

Does Bariatric Surgery Cause Vitamin A, B1, C or E Deficiency? A Systematic Review.

BACKGROUND: The restrictive and/or malabsorptive nature of bariatric surgery may increase the risk for micronutrient deficiencies. This systematic review aimed to identify and critique the evidence for vitamin A, B1, C or E deficiencies associated with bariatric surgery. METHODS: This review utilised PRISMA and MOOSE frameworks with NHMRC evidence hierarchy and the American Dietetic Association bias tool to assess the quality of articles. RESULTS: Twenty-one articles were included and once critiqued all studies were of level IV grade and neutral or negative in quality. The relevance of measuring micronutrient supplementation and inflammatory markers for validity of serum vitamins is absent within the literature. CONCLUSIONS: Future research is needed to investigate the risk of deficiency for these procedures with focus on confounders to serum micronutrients.

Comparison of Patient Food Intake, Satisfaction and Meal Quality Between Two Meal Service Styles in a Geriatric Inpatient Unit.

This pilot study evaluated the introduction of a bistro evening meal service in a geriatric inpatient unit by comparing patient intake, satisfaction and meal quality of this new service to the usual central preplated service. Ten meals were observed under each condition (n = 30; mean age 79 years, 47% male). Data were collected on intake of each meal component (none, », ½, ¾, all; converted to energy and protein using known food composition data), patient satisfaction with meals (meal flavor/taste, appearance, quality, staff demeanor; seven-point scale) and meal quality (sensory properties, temperature; five-point scale). Independent t-tests were used to compare energy and protein intakes between bistro and preplated services. There was no difference in mean energy or protein intake (energy: 2524 ± 927 kJ vs. 2692 ± 857 kJ, p = 0.612; protein: 29 ± 12 g vs. 27 ± 11 g, p = 0.699) patient satisfaction or meal quality between the bistro and preplated meal services. Patients were provided with fewer meal items during the bistro service, but ate a higher proportion of what was provided to them. Implementing a bistro service did not increase intake, satisfaction or meal quality in this study, suggesting that meal plating may be only one of many factors influencing intake and satisfaction of older inpatients.
