Quality of life in patients and in family members of those receiving home parenteral support with intestinal failure: A systematic review

Emerging drugs for the treatment of short bowel syndrome

INTRODUCTION

SBS is a rare and disabling condition. The standard management is based on diet optimization with parenteral supplementation. In addition, glucagon-like peptide-2 (GLP-2)analogs, have shown promising results as disease-modifying therapies for SBS.

AREAS COVERED

Short bowel syndrome (SBS) is defined as a reduction in functional intestinal length to less than 200 cm, leading to intestinal failure (IF) leading to malnutrition and parenteral support dependency. This review discusses the current management of SBS-CIFpatients, the place of GLP-2 analog treatment in terms of efficacy, safety and availability, and the new perspectives opened by the use of enterohormones.

EXPERT OPINION

Clinical trials and real-world experience demonstrated that Teduglutide   reduces dependence on parenteral support and has a place in the management of patients with SBS-CIF.  The use of Teduglutide should be discussed in patients stabilized after resection and its introduction requires the advice of an expert center capable of assessing the benefit-risk ratio. The complex, individualized management of SBS-C IF requires theexpertise of a specialized IF center which a multidisciplinary approach. The arrival of new treatments will call for new therapeutic strategies, and the question of how to introduce and monitor them will represent a new therapeutic challenge.

The Anxiety Burden in Patients with Chronic Intestinal Failure on Long-Term Parenteral Nutrition and in Their Caregivers

Background and aims: Home parenteral nutrition (HPN) is a life-saving treatment for patients affected by chronic intestinal failure (CIF). Both this clinical condition and its therapy require radical lifestyle modifications, affecting life quality and psychological balance in patients as well as family members. Patient psychological burden has rarely been taken into consideration, not to mention that of caregivers. This study aims to evaluate the levels of anxiety in CIF patients on HPN, and their caregivers, consequently determining their impact on the psychological and physical aspects. Methods: After a brief introductory interview, adult patients on HPN for CIF and their caregivers were asked to fill in the HAMA-A questionnaire. Results: Fifty patients and their respective caregivers were enrolled. Mean HAMA-A scores were similar in patients and caregivers and testified the presence of a mild to severe impact of CIF and HPN in both groups, with a significantly higher impact on female patients and caregivers. After adjusting age, education level, duration of CIF and HPN dependence, and degree of kinship, no differences were revealed in the scores. Conclusions: The study confirms that CIF patients on HPN and their caregivers have a significant anxiety burden independently from the duration of the disease, therefore needing appropriate support.

ESPEN guideline on chronic intestinal failure in adults - Update 2023

BACKGROUND & AIMS

In 2016, ESPEN published the guideline for Chronic Intestinal Failure (CIF) in adults. An updated version of ESPEN guidelines on CIF due to benign disease in adults was devised in order to incorporate new evidence since the publication of the previous ESPEN guidelines.

METHODS

The grading system of the Scottish Intercollegiate Guidelines Network (SIGN) was used to grade the literature. Recommendations were graded according to the levels of evidence available as A (strong), B (conditional), 0 (weak) and Good practice points (GPP). The recommendations of the 2016 guideline (graded using the GRADE system) which were still valid, because no studies supporting an update were retrieved, were reworded and re-graded accordingly.

RESULTS

The recommendations of the 2016 guideline were reviewed, particularly focusing on definitions, and new chapters were included to devise recommendations on IF centers, chronic enterocutaneous fistulas, costs of IF, caring for CIF patients during pregnancy, transition of patients from pediatric to adult centers. The new guideline consist of 149 recommendations and 16 statements which were voted for consensus by ESPEN members, online in July 2022 and at conference during the annual Congress in September 2022. The Grade of recommendation is GPP for 96 (64.4%) of the recommendations, 0 for 29 (19.5%), B for 19 (12.7%), and A for only five (3.4%). The grade of consensus is "strong consensus" for 148 (99.3%) and "consensus" for one (0.7%) recommendation. The grade of consensus for the statements is "strong consensus" for 14 (87.5%) and "consensus" for two (12.5%).

CONCLUSIONS

It is confirmed that CIF management requires complex technologies, multidisciplinary and multiprofessional activity, and expertise to care for the underlying gastrointestinal disease and to provide HPN support. Most of the recommendations were graded as GPP, but almost all received a strong consensus.

The impact of targeted interventions aimed to improve quality of life in patients receiving home parenteral nutrition: A systematic literature review

BACKGROUND

Home parenteral nutrition (HPN) is a specialised therapy offered to people suffering from intestinal failure. Underlying disease, HPN complications and limitations of HPN can significantly impact a person's quality-of-life (QOL). The aim of this review was to evaluate the evidence on existing non-surgical/non-pharmacological interventions aimed at improving QOL, clinical, patient-reported and economic outcomes for patients receiving parenteral nutrition therapy at home across adult and paediatric settings.

METHODS

Online databases Medline (Ovid), Embase and Cinahl were searched to identify studies published between 1937 and 31 March 2022. Identified studies were appraised using the Cochrane Collaboration risk of bias tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment.

RESULTS

Nine studies were included in this review. Interventions were focused on education (n = 4), telemedicine (n = 2), preparation of infusion mixtures (n = 1), mindfulness-based cognitive therapy (n = 1) and a multi-modal approach (n = 1). Only one study measured QOL before and after the intervention using a validated QOL tool. All studies were assessed at either some, high or critical risk of bias, resulting in low or very low-quality evidence for the interventions evaluated.

CONCLUSIONS

The findings from this review highlight the lack of high-quality non-surgical/non-pharmacological studies seeking to improve QOL for people on HPN. Because the majority of people receiving HPN are not eligible for surgical or pharmaceutical treatments, higher quality research using clinical trial design, and research focused on improving QOL is needed to inform healthcare managers about the effectiveness (and value) of alternative service delivery models for this vulnerable patient group.

Epidemiology, survival, costs, and quality of life in adults with short bowel syndrome

Short bowel syndrome (SBS) is a rare disorder with known physical, psychosocial, and economic burdens and significant morbidity and mortality. Many individuals with SBS require long-term home parenteral nutrition (HPN). The incidence and prevalence of SBS is difficult to determine because it is often based on HPN usage and may not account for those who receive intravenous fluids or achieve enteral autonomy. The most common etiologies associated with SBS are Crohn's disease and mesenteric ischemia. Intestinal anatomy and remnant bowel length are prognostic for HPN dependency, and enteral autonomy confers a survival advantage. Health economic data confirm that PN-related costs are higher for hospitalizations than at home; yet significant healthcare resource utilization is necessary for successful HPN, and patients and families report substantial financial distress that impacts quality of life (QOL). An important advancement in QOL measurement is the validation of HPN- and SBS-specific QOL questionnaires. In addition to the known factors negatively impacting QOL, such as diarrhea, pain, nocturia, fatigue, depression, and narcotic dependency, research has shown that the volume and number of PN infusions per week is associated with QOL. Although traditional QOL measurements describe how underlying disease and therapy influence life, they do not assess how symptoms and functional limitations affect the QOL of patients and caregivers. Patient-centered measures and conversation focused on psychosocial issues helps patients with SBS and HPN dependency better cope with their disease and treatment. This article presents a brief overview of SBS, including epidemiology, survival, costs, and QOL.

Survey of healthcare professionals' experiences of care delivery in patients with chronic intestinal failure: ATLAS of Variance

BACKGROUND AND AIM

Chronic intestinal failure (IF) is a rare but life-altering condition, care delivery of which is complex. The ATLAS Programme was initiated in 2016 to increase disease awareness and address inconsistencies in delivery of care across Europe. We describe the results of a non-interventional study that aimed to explore how adult patients with chronic IF are managed across Europe.

MATERIALS AND METHODS

This mixed-methods, non-interventional, cross-sectional study comprised a desk-based landscape assessment (Phase 1), qualitative interviews (Phase 2), and an online quantitative survey (Phase 3) completed by healthcare professionals (HCPs) involved in the management of adult patients with chronic IF during the period November 2020 to January 2021. Data were collected from 12 European countries. Survey data were anonymised and pooled for analysis at European and country level. Responses were summarised as frequencies, ranks and percentage.

RESULTS

The quantitative survey was carried out on 119 HCPs across an estimated 58 centres. Gastroenterology was the most frequent specialty of respondents (45%). Three-quarters of HCPs (N = 119) reported that their department/unit had a multidisciplinary team for the management of patients with chronic IF. HCPs reported improving quality of life (QoL) to be the most important goal of treatment (39%), followed by reducing mortality (25%), intestinal rehabilitation (20%) and reducing morbidity (9%). Similarly, 63% of HCPs responded that improved QoL was the most important treatment goal from the perspective of their patients. Overall, 87% of HCPs reported that patients with chronic IF routinely receive home parenteral nutrition (HPN) in their country, which was more common in Western versus Eastern Europe. Meeting treatment goals (53%) and achieving better levels of support with HPN (44%) were reported as the main challenges faced by HCPs in the management of patients with chronic IF. A general lack of disease awareness of chronic IF among HCPs (46%), and insufficient accredited patient referral centres (41%) were considered the most important areas for improvement.

CONCLUSIONS

HCPs specialising in treating chronic IF considered that improvement in QoL is needed for their patients. They reported a low level of awareness of chronic IF among non-specialist HCPs.

In their shoes: Health care professionals walking a day in the life of patients with short bowel syndrome & intestinal failure

BACKGROUND & AIMS

Short bowel syndrome leading to intestinal failure (SBS-IF) is a condition characterised by the inability of the gut to absorb the amount of water, nutrients and micronutrients needed to survive and requires long term home parenteral nutrition (HPN) to sustain life. Health care professionals (HCPs) working with patients with SBS-IF are aware of the daily challenges patients face. However, few have experienced the condition first-hand and put themselves 'in the shoes' of their patients. In Their Shoes (ITS) is an immersive simulation delivered through a smartphone application (app), in which participants experience the typical real-life challenges that somebody with SBS-IF will experience over a 24-h period, including social and psychological challenges. This study evaluated the impact of ITS simulation on HCPs working with adults with SBS-IF.

METHODS

A representative sample of 27 multi-disciplinary team (MDT) members working on an Intestinal Failure Unit completed the ITS simulation over a 24-h period. A mixed methods design was used, which included participants completing a survey pre- and post-ITS experience, followed by focus groups and in-depth qualitative interviews. Pre- and post-intervention questions were analysed quantitively via paired t-tests and qualitative data arising from the focus groups and interviews were analysed using inductive thematic analysis.

RESULTS

25 participants (93%) completed 80% of the ITS challenges whilst 27 (100%) completed more than 50% challenges. Participants reported a 16% increase in knowledge, 18% increase in being able to talk to others about SBS and a 2% increase in empathy between pre- and post-simulation. Nineteen team members participated in focus groups and 10 in-depth interviews; qualitative analysis of digital recordings comprised four overarching themes: empathy; admiration and respect; empathy fatigue; learning experience. Despite the small and insignificant increase in empathy scores quantitatively, analysis of open-ended questions and qualitative data found that 74% of participants reported an increase in empathy levels whereas 26% felt it stayed the same.

CONCLUSIONS

As a simulation-based learning method, ITS can have a positive impact on HCPs working into the SBS-IF setting. Positive benefits in clinical practice include increased levels of empathy, admiration and respect for patients amongst HCPs. Immersing into the ITS experience also allows HCPs to recognise the function and benefits to MDT working, both in terms of ensuring holistic patient centred care and managing HCP empathy fatigue.

Investigating the Relationship between Home Parenteral Support and Needs-Based Quality of Life in Patients with Chronic Intestinal Failure: A National Multi-Centre Longitudinal Cohort Study

Home parenteral support (HPS) is an essential but potentially burdensome treatment that can affect quality of life (QoL). The aims of this longitudinal study were to understand whether any changes in HPS over time were associated with QoL. The Parenteral Nutrition Impact Questionnaire (PNIQ) was used, and data were collected on HPS prescribed at three time points. Data were analysed using multi-level mixed regression models presented as effect size and were adjusted for confounders. Study recruited 572 participants from 15 sites. Of these, 201 and 145 completed surveys at second and third time-points, respectively. PNIQ score was out of 20 with a higher score indicating poorer QoL. Any reduction in HPS infusions per week was associated with an improved PNIQ score of -1.10 (95% CI -2.17, -0.02) unadjusted and -1.34 (95% CI -2.45, -0.24) adjusted. Per day change to the number of infusions per week was associated with a change in the PNIQ score of 0.32 (95% CI -0.15, 0.80) unadjusted and 0.34 (95% CI -0.17, 0.85) adjusted. This is the largest national study to demonstrate improvements in QoL associated with HPS reduction over time using an HPS-specific and patient-centric tool, adding unique data for use of therapies in intestinal failure.

Efficacy of Teduglutide for Parenteral Support Reduction in Patients with Short Bowel Syndrome: A Systematic Review and Meta-Analysis

Teduglutide has been described as an effective treatment for parenteral support (PS) reduction in patients with short bowel syndrome (SBS). However, a quantitative summary of the available evidence is still lacking. PubMed/Medline, EMBASE, Cochrane library, OVID, and CINAHL databases were systematically searched up to July 2021 for studies reporting the rate of response (defined as a ≥20% reduction in PS) to teduglutide among PS-dependent adult patients. The rate of weaning (defined as the achievement of PS independence) was also evaluated as a secondary end-point. Ten studies were finally considered in the meta-analysis. Pooled data show a response rate of 64% at 6 months, 77% at 1 year and, 82% at ≥2 years; on the other hand, the weaning rate could be estimated as 11% at 6 months, 17% at 1 year, and 21% at ≥2 years. The presence of colon in continuity reduced the response rate (-17%, 95%CI: (-31%, -3%)), but was associated with a higher weaning rate (+16%, 95%CI: (+6%, +25%)). SBS etiology, on the contrary, was not found to be a significant predictor of these outcomes, although a nonsignificant trend towards both higher response rates (+9%, 95%CI: (-8%, +27%)) and higher weaning rates (+7%, 95%CI: (-14%, +28%)) could be observed in patients with Crohn's disease. This was the first meta-analysis that specifically assessed the efficacy of teduglutide in adult patients with SBS. Our results provide pooled estimates of response and weaning rates over time and identify intestinal anatomy as a significant predictor of these outcomes.

Impact of home parenteral nutrition on family members: A national multi-centre cross-sectional study

BACKGROUND & AIMS

Home parenteral nutrition (HPN) is a necessary treatment for patients with chronic, type 3, intestinal failure (IF). HPN often requires lifestyle adaptations, which are likely to affect quality of life (QoL) in both patients and family members. The aim of this study was to identify the level of burden on family members who are involved with HPN care and to understand specific factors that contribute to any burden.

METHODS

Patients over the age of 18 and receiving HPN were identified in IF clinics from multiple centres across the U.K. Eligible patients were asked to complete the parenteral nutrition impact questionnaire (PNIQ) to assess their QoL, while family members were asked to complete the burden scale for family caregivers (BSFC). Logistical regression was undertaken giving adjusted odds ratios (aOR).

RESULTS

678 participants completed the survey representing 339 patients with their appointed family member. Mean PNIQ score was 11.53 (S.D. 5.5), representing a moderate impact of HPN on patients' QoL. On the BSFC scale, 23% of family members reported a moderate to very severe subjective burden indicating an increased risk of psychosomatic symptoms. After adjusting for age and gender, predictors of BSFC included: family members self-reported health status using the EuroQol visual analogue scale (aOR 19.91, 95% CI 1.69, 233.99, p = 0.017) and support received by health services (aOR = 5.83, 95% CI = 1.93, 17.56, p = 0.002). Employment status, disease type, number of nights on HPN and length of time on HPN were not associated with BSFC.

CONCLUSIONS

Family members with a poor health status or lack of support by health service were more likely to have a moderate to very severe subjective burden. Tailored support from the multi-professional IF team may reduce the burden experienced by family members of people dependent on HPN.

Nutritional considerations in severe primary chronic small intestinal dysmotility

PURPOSE OF REVIEW

To provide an update on the recent evidence underpinning the approach to nutritional care in patients with severe primary chronic small bowel dysmotility.

RECENT FINDINGS

Patients with severe chronic small intestinal dysmotility suffer nutritional and nonnutritional morbidity, both as a result of their underlying polysymptomatic, poorly understood condition and the interventions required. A proportion require artificial nutrition support; however, this is associated with impaired quality of life and associated complications. The approach to nutritional support must therefore engage a multidisciplinary team (MDT) to ensure that decisions to escalate beyond oral nutrition reflect individualised risk-benefit discussions while adopting a holistic approach to symptom management. Since nutritional outcomes are worse in those with the chronic intestinal pseudo-obstruction (CIPO) phenotype, differentiation into CIPO and non-CIPO subgroups, using a pragmatic diagnostic approach rather than invasive/poorly tolerated investigations, can be an important step in achieving nutritional care tailored to the individual.

SUMMARY

Malnutrition in patients with severe chronic small intestinal dysmotility is multifactorial. Early engagement of a broad team that includes dietitians, psychologists and pain management experts is crucial to achieving the most beneficial and least harmful patient-centred nutritional care outcomes.
