The purpose of this overview is to make the case for the establishment and publication of standards for home enteral nutrition (HEN) therapy in adult patients who require a long-term alternative to oral feeding. Overviews can provide a broad and often comprehensive summation of a topic area and, as such, have value for those coming to a subject for the first time. It will provide a broad summation, background and rationale, review specific considerations unique to HEN (tubes, products and supplies) and we describe a recent audit of seven HEN programs which highlights tube and process related challenges. Based on the overview of the literature and our experience with the audit we propose a way forward for best home enteral nutrition care.

AbstractBackgroundDiabetes mellitus (DM) is estimated to affect 9% of Americans and is associated with significant morbidity, mortality, and increased healthcare costs.MethodsA retrospective review of a home enteral nutrition (HEN) database of patients seen between March 1, 2004, and April 31, 2014, at our institution was conducted to identify HEN patients who had a diagnosis of DM or were diagnosed within the acute period (4 months) of starting HEN therapy.Results174 (3.7%) of 4682 patients in the HEN program had DM. HEN was provided through a gastrostomy tube in 82 patients and through a jejunostomy tube in 92 patients. At 3 months, data were available for 42 gastrostomy patients; 44% had a change in DM management, with 60% undergoing a change to insulin. Similarly, 34 patients with jejunostomy had data available, with 41% undergoing change in medication and 93% being changed to insulin therapy. For patients with available glycated hemogloblin values, at 3 months the gastrostomy patients noted a decrease of 0.5% (7.3% ± 1.1% to 6.8% ± 0.7%, not significant) and the jejunostomy patients noted a decrease of 0.4% (6.9% ± 0.9% to 6.5% ± 1.1%, P = .06). Conclusions: Overall, our results suggest that closer follow‐up and laboratory assessment are necessary for management of HEN patients with DM. In those with data available, glycemic control can be maintained in patients receiving HEN with appropriate adjustment of DM management and focus on ensuring that patients are not overfed.

AbstractBackgroundEnteral nutrition (EN) is a safe and cost‐effective intervention with significant morbidity and mortality benefit that can also be associated with complications. Peristomal infections can occur in 5%–30% of cases after percutaneous endoscopic gastrostomy placement. Despite this common occurrence, widespread use of objective diagnostic criteria is not prevalent, possibly leading to overuse of antibiotics.MethodsAll patients who were reporting symptoms consistent with peristomal infection were evaluated. Criteria based on erythema, induration, and exudates were applied with cumulative score ≥8 indicating peristomal infection. All patients were followed, with additional factors being collected if available.ResultsForty‐three patients noted complaints consistent with peristomal infection. In patients with a score <8 (n = 16), only 2 required antibiotics (12.5%) and 1 patient was hospitalized (6.3%). In patients with a score ≥8 (n = 27), 16 had a score of 8 or 9; all patients responded to antibiotics (100%), and 1 was hospitalized (6.3%). In patients with a score ≥10, all (100%) were treated with antibiotics. Five of 11 (45%) patients were hospitalized, with the most common diagnosis being sepsis. Of the baseline variables analyzed, higher body mass index correlated with score ≥10 (26.36 ± 2.94 vs 22.91 ± 4.35 in score <9, P = .0128).ConclusionsObjective criteria were effective in risk stratifying patients who presented with reports of peristomal infection. Patients with a score <8 tended to be at low risk, scores of 8–9 were of moderate risk, and patients with a score ≥10 were at high risk and required very close monitoring or hospitalization.

AbstractBackgroundDespite the importance of home enteral nutrition (HEN), there is a lack of understanding within the medical and general community of how HEN impacts the lives of patients and caregivers. Using a theoretical orientation that attends to the materiality of both everyday and medical objects, we explored patients' and family caregivers' everyday experiences of administering feeds during HEN.MethodsUsing the photo‐elicitation interviewing method, patients on HEN and their family caregivers were asked to take up to 10 photographs to portray material items and activities that they considered foundational to HEN. They subsequently narrated their experiences and the participant‐generated photographs in an interview. Participant‐generated photographs (126) and accompanying narratives were analyzed using layered analysis, and results were theorized with attention to both social and material significance of HEN.ResultsPatients and caregivers detailed overcoming misconceptions of HEN, and through their use of photographs, they conveyed their expertise in developing their own HEN feeding systems and practices, that used both the material artifacts provided by the hospital (the tube, syringe, and formula) as well as everyday material items found in the patient's home. More than this, photographs and patient narratives depicted intimate involvement of patients' families in tube feeding. This yielded a more comprehensive understanding of the material and experiential realities of HEN.ConclusionHome enteral nutrition was found to be a shared familial experience, that in addition to requiring medical equipment also incorporated ordinary material artifacts within the social setting of the home and family life. To more accurately convey the material, experiential, and social realities of HEN to future patients, our findings underscore the importance of drawing on both visual and textual forms of patient‐produced information in the development of HEN patient educational materials.

AbstractBackground: Since initial report in 1972, misconnections continue to be an issue, especially in hospitalized patients with multiple access devices. A new small‐bore connector standard (ENFit) has been proposed in order to minimize misconnections. Methods: Commercially available finalized ENFit tubes of a variety of sizes (14 French [Fr] size, 18Fr, 20Fr, 24Fr, and low‐profile) were obtained for current testing. Variety of commercially available formulas including blenderized tube feeding (BTF) products (Jevity 1 Cal, Abbott Nutrition, Abbott Park, IL; Nourish, Functional Formularies, Centerville, OH; Real Food Blends, Chesterton, IN) were tested. Results: Data from individual measurements were aggregated for ENFit and legacy tubes and revealed higher syringe compression force in legacy tubes compared with ENFit tubes for 20Fr size with Jevity formula. Our institution's BTF formula revealed that legacy tubes had lower syringe compression force than ENFit tubes for 14Fr tube size. Remaining measurements revealed no significant difference. Model 1 of regression analysis revealed that only formula and tube size were significant with R2 of 0.63. Model 2 evaluating the impact of tube size, blender, time of blending, and legacy vs ENFit revealed that tube size, blender used, and blending time were significant with legacy vs ENFit being nonsignificant (R2 of 0.72). Conclusions: Overall, only a small number of tube sizes (14Fr and 20Fr) with selected formulas revealed a significant difference between ENFit and Legacy tubes, with remaining studies finding no significant difference. Regression analysis revealed that variables such as formula, size of tube, blender used, and time of blending may have more impact on compression force.

ABSTRACT Background and purpose: Diabetes mellitus is an epidemic. Many organizations and states have established reportable quality care measures. Our organization explored novel ways of chronic disease management. The purpose of this article is to decrease the percentage of patients with a hemoglobin A1c (HbA1c) more than 8%. Methods: Prospective, pre- and postintervention, quality improvement project was implemented in the Employee and Community Health Clinic using an endocrinology nurse practitioner (NP) to coordinate and provide care to adult patients with diabetes. A convenience sample of 103 patients with diabetes was selected for this project. Patients were excluded from the project if they did not complete preintervention satisfaction surveys or did not sign research release forms. Conclusions: One hundred three patients were referred, and two met exclusion criteria. Of those patients, 51% were female with an average HbA1c of 9.1%. Eighty-one of the referred patients attended their appointment. The patients who sought care had a reduction in HbA1c from 9.0% ± 1.8% to 8.3% ± 1.7% (p value < .001). Patients who did not appear had no significant change in their HbA1c from 9.8% ± 3.1% to 9.4% ± 2.7% (p value = .61). Implications for practice: Incorporating specialty trained NPs can lead to improvements in HbA1c, patient-reported control of diabetes, and a reduction in the frequency of hypoglycemia.

Abstract Background Despite providing significant benefits, home parenteral nutrition (HPN) can be associated with complications such as infections, intestinal failure–associated liver disease, and metabolic abnormalities. Soybean oil (SO)–based intravenous lipid emulsion (ILE) has been noted to contribute to some of these complications, leading to the development of alternative sources of ILE. Mixed‐oil (MO) ILE has recently been approved for use in adults with short‐term studies revealing a benefit over SO ILE. Currently there is a paucity of data regarding long‐term use in the HPN population. Methods The current study reports our experience with MO ILE in 9 HPN patients. Results A total of 9 patients (3 women and 6 men) with average age of 48.1 ± 15.1 years and a median HPN use of 9.9 years (9.0 months–30.7 years) were transitioned from SO ILE to MO ILE as a result of intolerance. The 9 patients tolerated MO ILE well for 140.7 ± 29.7 days. The percentage of calories provided through ILE increased from 7.6 ± 6.5% to 18.4 ± 8.2% ( P = .003), whereas the dextrose decreased from 66.9 ± 8.4% to 56.9 ± 5.5% ( P = .0007). Although statistical significance was not reached, there was a trend toward improvement in alkaline phosphatase from 138.0 (52–884) to 106 (47–512; P = .09). Conclusion MO ILE was well tolerated in this small cohort and led to improvement in the macronutrient composition of HPN while providing a trend toward improvement in liver studies. These results are promising; however, additional randomized control trials are needed to delineate the true benefit.

Insulin stimulates the translocation fatty acid transport protein 1 (FATP1) to plasma membrane, and thus greater free fatty acid (FFA) uptake, in adipocyte cell models. Whether insulin stimulates greater FFA clearance into adipose tissue in vivo is unknown. We tested this hypothesis by comparing direct FFA storage in subcutaneous adipose tissue during insulin versus niacin-medicated suppression of lipolysis. We measured direct FFA storage in abdominal and femoral subcutaneous fat in 10 and 11 adults, respectively, during euglycemic hyperinsulinemia or after oral niacin to suppress FFA compared with 11 saline control experiments. Direct palmitate storage was assessed using a [U-13C]palmitate infusion to measure palmitate kinetics and an intravenous palmitate radiotracer bolus/timed biopsy. Plasma palmitate concentrations and flux were suppressed to 23 ± 3 and 26 ± 5 µmol ⋅ L−1 (P = 0.91) and 44 ± 4 and 39 ± 5 µmol ⋅ min−1 (P = 0.41) in the insulin and niacin groups, respectively, much less (P &lt; 0.001) than the saline control group (102 ± 8 and 104 ± 12 µmol ⋅ min−1, respectively). In the insulin, niacin, and saline groups, abdominal palmitate storage rates were 0.25 ± 0.05 vs. 0.25 ± 0.07 vs. 0.32 ± 0.05 µmol ⋅ kg adipose lipid−1 ⋅ min−1, respectively (P = NS), and femoral adipose storage rates were 0.19 ± 0.06 vs. 0.20 ± 0.05 vs. 0.31 ± 0.05 µmol ⋅ kg adipose lipid−1 ⋅ min−1, respectively (P = NS). In conclusion, insulin does not increase FFA storage in adipose tissue compared with niacin, which suppresses lipolysis via a different pathway.

ObjectiveTo report the impact of bariatric surgery on metabolic outcomes in patients with type 1 diabetes (DM1) versus insulin‐requiring type 2 diabetes mellitus (IRDM2).MethodsTen subjects with DM1 were compared with 118 subjects with IRDM2 at baseline and at 1 and 2 years post‐bariatric surgery for: anthropometric measures, HbA1c, and number of medications (anti‐hyperglycemic, anti‐hypertensive, lipid‐lowering).ResultsDM1 and IRDM2 groups lost similar amounts of weight 2 years post‐bariatric surgery (39.5 ± 14.7 kg vs. 40.3 ± 24.4 kg). IRDM2 subjects had significant improvements in HbA1c (7.8% ± 1.4% vs. 6.8% ± 1.4%, P value <0.0001) and decreases in number of anti‐hyperglycemic (2.4 ± 0.8 vs. 0.7 ± 0.8, P value <0.0001), anti‐hypertensive (2.2 ± 1.3 vs. 1.3 ± 1.2, P value <0.0001), and lipid‐lowering (1.1 ± 0.8 vs. 0.6 ± 0.6, P value <0.0001) medications. DM1 subjects had no improvement in HbA1c (8.2% ± 1.6% vs. 7.8% ± 0.9%) or use of anti‐hypertensive medications (2.1 ± 1.4 vs. 2.3 ± 1.5). Their use of lipid‐lowering medications improved (1.0 ± 0.5 vs. 0.5 ± 0.8, P value 0.04).ConclusionsOur study suggests that improved glycemic control may not be an expected outcome when considering bariatric surgery in patients with DM1; however, additional investigation is warranted.
