Long-Term Home Parenteral Nutrition: It Takes an Interdisciplinary Approach

Characteristics and outcomes of home parenteral nutrition among children with severe neurological impairment

OBJECTIVES

To describe the characteristics, secular trends, and outcomes of home parenteral nutrition (HPN) use among children with severe neurological impairment (SNI) and non-primary digestive disorders from 2010 to 2023 and compare outcomes to children with primary digestive disorders on HPN.

METHODS

A retrospective review of all children with SNI and non-primary digestive disorders, where HPN was initiated between January 2010 and September 2023 at a tertiary care pediatric hospital. The Mann-Kendall trend test was used to assess trends in HPN initiation. We compared acute care service utilization in the year prior and following HPN initiation. Mortality and ability to achieve enteral autonomy outcomes were compared to those of children with HPN and primary digestive disorders.

RESULTS

Of the 205 included children with HPN, 18 children had SNI and non-primary digestive disorders, 187 children had primary digestive disorders. There was an increase in HPN initiation among children with SNI and non-primary digestive disorders (p = 0.002) between 2010 and 2020. Among children with SNI and non-primary digestive disorders, HPN-related complications (line-associated infection/thrombus, nephrolithiasis, cholelithiasis) occurred in 72%. There was no change in acute care utilization in the year prior versus year following HPN initiation. Compared with the primary digestive disorders group, children with SNI and non-primary digestive disorders were less likely to achieve enteral autonomy (p < 0.0001); however, no significant differences in mortality were observed (22% vs. 8%, p = 0.09).

CONCLUSIONS

HPN is increasingly being used among SNI children with non-primary digestive disorders. Compared to children with primary digestive disorders on HPN, those with SNI are less likely to achieve enteral autonomy.

Parenteral nutrition at home/long-term parenteral nutrition

PURPOSE

Some diseases require that patients receive parenteral nutrition (PN) over a prolonged time period. Long-term administration of PN can further complicate an already complex therapy, posing additional risk of potential complications. This article is based on presentations and discussions held at the International Safety and Quality of PN Summit, providing insights into aspects of home PN (HPN) and examples of good HPN practice.

SUMMARY

One critical step in the HPN process is when patients transition from a hospital to a home setting, and vice versa. Generally, electronic PN ordering is not feasible in an HPN setting, leading to potential difficulties in communication and coordination. HPN requires that patients (or their home caregivers) administer PN, and thus their education and competency are crucial. Likewise, the choice of PN formulation is of great importance. For example, using more modern intravenous lipid emulsions containing medium-chain triglycerides, olive oil, and/or fish oil can provide benefits in terms of liver function during long-term HPN. Internationally, there are wide variations in delivery of HPN, with compounded PN dominating in some countries while others make greater use of market-authorized multichamber bags (MCBs). Patient-related factors, institutional considerations, and the availability of different MCB formulations, are also contributing factors guiding formulation and delivery system preferences.

CONCLUSION

Education and communication remain key components of a successful HPN process. The information shared here may help to motivate efforts to improve HPN processes and to consider the often-differing perspectives of patients and their healthcare professionals.

Comparison between self-reported and actigraphy-derived sleep measures in patients receiving home parenteral nutrition: Secondary analysis of observational data

BACKGROUND

Patients receiving home parenteral nutrition (HPN) frequently report disrupted sleep. However, there are often inconsistencies between objectively measured and questionnaire-derived sleep measures. We compared sleep measures estimated from wrist actigraphy and self-report in adults receiving HPN.

METHODS

In this secondary analysis, we pooled data from two sleep-related studies enrolling adults receiving habitual HPN. We compared measures from 7-day averages of wrist actigraphy against comparable responses to a sleep questionnaire. Sleep measures included bedtime, wake time, time in bed, total sleep time, and sleep onset latency (SOL). Spearman correlation coefficients, Bland-Altman plots, and linear regression models for each set of sleep measures provided estimates of agreement.

RESULTS

Participants (N = 35) had a mean age of 52 years, body mass index of 21.6 kg/m2 , and 77% identified as female. Correlation coefficients ranged from 0.35 to 0.90, were highest for wake time (r = 0.90) and bedtime (r = 0.74), and lowest for total sleep time (r = 0.35). Actigraphy overestimated self-reported bedtime, wake time, and total sleep time and underestimated self-reported time in bed and SOL. Regression coefficients indicated the highest calibration for bedtime and wake time and lower calibration for time in bed, total sleep time, and SOL.

CONCLUSION

We observed strong-to-moderate agreement between sleep measures derived from wrist actigraphy and self-report in adults receiving HPN. Weaker correlations for total sleep time and SOL may indicate low wrist actigraphy sensitivity. Low-quality sleep resulting from sleep disruptions may have also contributed to an underreporting of perceived sleep quantity and lower concordance.

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.

Short bowel syndrome: Complications and management

Short bowel syndrome (SBS) occurs when a patient loses bowel length or function significantly enough to cause malabsorption, oftentimes requiring lifelong parenteral support. In adults, this occurs most commonly in the setting of massive intestinal resection, whereas congenital anomalies and necrotizing enterocolitis predominate in children. Many patients with SBS develop long-term clinical complications over time related to their altered intestinal anatomy and physiology or to various treatment interventions such as parenteral nutrition and the central venous catheter through which it is administered. Identifying, preventing, and treating these complications can be challenging. This review will focus on the diagnosis, treatment, and prevention of several complications that can occur in this patient population, including diarrhea, fluid and electrolyte imbalance, vitamin and trace element derangements, metabolic bone disease, biliary disorders, small intestinal bacterial overgrowth, d-lactic acidosis, and complications of central venous catheters.

ESPEN practical guideline: Home parenteral nutrition

This guideline will inform physicians, nurses, dieticians, pharmacists, caregivers and other home parenteral nutrition (HPN) providers, as well as healthcare administrators and policy makers, about appropriate and safe HPN provision. This guideline will also inform patients requiring HPN. The guideline is based on previous published guidelines and provides an update of current evidence and expert opinion; it consists of 71 recommendations that address the indications for HPN, central venous access device (CVAD) and infusion pump, infusion catheter and CVAD site care, nutritional admixtures, program monitoring and management. Meta-analyses, systematic reviews and single clinical trials based on clinical questions were searched according to the PICO format. The evidence was evaluated and used to develop clinical recommendations implementing Scottish Intercollegiate Guidelines Network methodology. The guideline was commissioned and financially supported by ESPEN and members of the guideline group were selected by ESPEN.

A Cross Sectional Survey-Based Study to Investigate the Availability and Utilisation of Home Nutrition Support in Saudi Arabia

Background and Aims

Many patients require long-term nutrition support, typically in the form of home nutrition support (HNS). The availability and utilisation of HNS in Saudi Arabia is currently unknown; therefore, this study was conducted to assess the availability of HNS in Saudi hospitals and to explore factors associated with the availability of HNS in different healthcare facilities in Saudi Arabia.

Methods

A cross-sectional study was conducted among physicians, dietitians, and pharmacists working in Saudi Arabia with regular practice in nutrition support. Data was collected through self-administered web-based survey, which was distributed via social-media platforms.

Results

A total of 114 responses were received from healthcare providers involved in nutrition support across Saudi Arabia. Of the respondents, 55 (48.2%) indicated that nutrition support services were available at their facility. Regression analysis showed that other regions in Saudi Arabia had lower odds of having HNS compared with the Western region (OR=0.01; 95% CI=0.01-0.69). The university and specialised hospitals had lower odds of having HNS compared with Ministry of Health hospitals (OR=0.11; 95% CI=0.02-0.71, OR=0.11; 95% CI=0.02-0.56, respectively). Hospitals with capacities of 100-250 beds and 251-500 had higher odds of having HNS than smaller hospitals (OR=13.17; 95% CI=1.09-159.5, OR=3.11; 95% CI=2.04-248.77, respectively).

Conclusion

There is lack of published reports from hospitals with implemented HNS. Therefore, it is difficult to assess the current situation of HNS programmes. Future national studies focusing on HNS are warranted as there is a rising international trend in the number of patients requiring HNS.

Micronutrients in paediatric Intestinal Failure Patients receiving home parenteral nutrition

BACKGROUND & AIMS

Children with intestinal failure (IF) receive parental nutrition to ensure adequate growth and development. The aim of this study was to assess micronutrient status in paediatric IF patients receiving home parenteral nutrition (HPN) in comparison to a group of healthy children.

METHODS

An observational cross-sectional study was performed at Oslo University Hospital and at the Department of Nutrition, University of Oslo from January to September 2017. All children with IF, aged two to 18 years, were invited to participate. A reference group of healthy children was recruited through social media advertisement. Dietary intake was assessed by a four-day food record, and enteral and parenteral provision was recorded. Blood samples were analysed for vitamins, minerals and haematology to assess iron status. Two spot urine samples from each subject were analysed for iodine concentration (UIC) and creatinine.

RESULTS

Nineteen children with IF and 50 healthy children were included. The mean age of the participants was 10.0 years. IF-patients received a median of 76% of their estimated energy requirements from parenteral nutrition (PN). Recommended intake (RI) for iodine from the diet was reached by 16% of IF patients and 28% of healthy children. In the IF group there was a significant positive correlation between UIC and the percentage of iodine intake from oral diet and enteral nutrition support (r = 0.57, p = 0.03). Although the IF patients had a median parenteral iodine supply of more than twice the ESPGHAN recommendation, the median UIC was 89 μg/L indicating insufficient iodine status. This may suggest that the ESPGHAN recommendation for iodine in paediatric parenteral nutrition is too low. The healthy children had sufficient iodine status according to the median UIC (133 μg/L). IF patients had significantly lower total provision of iron compared to the healthy children, 4,9 vs 8,4 mg/day (p = 0.01) with 21% of IF patients and 28% of healthy children reaching RI for iron. The prevalence of anaemia was higher in IF patients than in the healthy children (40 vs.10%, p = 0.016).

CONCLUSION

The study indicates an insufficient iodine and iron status among paediatric IF patients. Iodine status was associated with enteral provision and patients had insufficient status even if they received the ESPGHAN recommendation of iodine.

Telemedicine Support Groups for Home Parenteral Nutrition Users

Patients receiving home parenteral nutrition (HPN), a life-sustaining intravenous (IV) infusion that provides nourishment and hydration to patients with short gut or inflammatory bowel diseases, are often isolated and not in visual contact with peers or health providers. One completed clinical trial (Clinical Trials.gov NCT0190028) and 1 ongoing clinical trial (Clinical Trials.gov NCT02987569) are evaluating a mobile videoconferencing-delivered support group intervention for patients on HPN and their caregivers. This home-based telemedicine intervention uses encrypted tablet-based videoconferencing to connect multiple families in real time. The twice-daily IV regimen is challenging for patients who may experience infusion catheter-related bloodstream infections, difficulties with fatigue, loss of sleep, depressive disorders, and worry over the potential life-threatening side effects and the expenses of this therapy. Using secure telemedicine, the facilitated support group intervention aims to enhance HPN home care, daily functioning, and quality of life. The authors provide the rationale for the telemedicine approach with HPN users and caregivers. They provide "how-to" information about the content and process of the facilitated support group sessions via secure videoconferencing. They share lessons learned from the ongoing evaluation of the telemedicine approach.

When Is Parenteral Nutrition Appropriate?

Parenteral nutrition (PN) represents one of the most notable achievements of modern medicine, serving as a therapeutic modality for all age groups across the healthcare continuum. PN offers a life-sustaining option when intestinal failure prevents adequate oral or enteral nutrition. However, providing nutrients by vein is an expensive form of nutrition support, and serious adverse events can occur. In an effort to provide clinical guidance regarding PN therapy, the Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) convened a task force to develop consensus recommendations regarding appropriate PN use. The recommendations contained in this document aim to delineate appropriate PN use and promote clinical benefits while minimizing the risks associated with the therapy. These consensus recommendations build on previous ASPEN clinical guidelines and consensus recommendations for PN safety. They are intended to guide evidence-based decisions regarding appropriate PN use for organizations and individual professionals, including physicians, nurses, dietitians, pharmacists, and other clinicians involved in providing PN. They not only support decisions related to initiating and managing PN but also serve as a guide for developing quality monitoring tools for PN and for identifying areas for further research. Finally, the recommendations contained within the document are also designed to inform decisions made by additional stakeholders, such as policy makers and third-party payers, by providing current perspectives regarding the use of PN in a variety of healthcare settings.

Defining the Specialty of Vascular Access through Consensus: Shaping the Future of Vascular Access

The Association for Vascular Access (AVA) is an organization of health care professionals founded in 1985 to support and promote the specialty of vascular access. The mission of AVA is to distinguish the vascular access specialty and define standards of vascular access through an evidence-based approach designed to enhance health care. There is little guidance for multidisciplinary procedures/practice, and this is the case for vascular access. There are also inconsistencies and conflicts in terminology. Additionally, there is no consensus of vascular access as a specialty. It is the focus of AVA to promote consistency in vascular access practice. This document embraces a common title for a clinician with knowledge and skills in the area of vascular access. This establishes a new paradigm that will strengthen the advancement of the vascular access specialty.
