Harnessing the Benefits of the Nutrition Care Process Quality Evaluation and Standardization Tool: A National Auditing Initiative to Improve Quality of Documentation.

The Nutrition Care Process Quality Standardization and Evaluation Tool (NCP QUEST) is a validated audit instrument assessing the quality of NCP documentation by registered dietitian nutritionists. The present quality improvement project describes change in documentation quality as measured by NCP QUEST and word count of notes after a monthly national digital training provided to Veterans Affairs registered dietitian nutritionists. The training and adoption of NCP QUEST was voluntary. Facilities were recruited among those that had participated during the design and validation study of NCP QUEST. The NCP QUEST score was calculated and the word count was determined for 52 documentation notes (28 from NCP QUEST nonuser facilities and 24 from NCP QUEST user facilities) before and after training. The mean pretraining NCP QUEST score for notes from NCP QUEST nonuser facilities was 13.71 and 13.88 for NCP QUEST user facilities. The mean posttraining total NCP QUEST score for nonuser facilities was 14.00 and 17.65 for user facilities, with no improvement for the nonuser facilities (P = 0.69). A significant improvement was identified for the NCP QUEST user facilities (P ≤ 0.001). All facilities experienced a significant reduction in the word count of assessment notes (P = 0.04). Use of the electronic NCP Terminology website increased 123-fold and was sustained after the training. NCP QUEST users reported that the audit tool is useful. The NCP QUEST should be at the center of registered dietitian nutritionists' training and more strategic effort is needed to engage practitioners in the optimal application of the NCP.

Nutrition Care Process Quality Evaluation and Standardization Tool: The Next Frontier in Quality Evaluation of Documentation.

Documentation is essential for communicating care between credentialed nutrition and dietetics practitioners and other health care providers. A validated tool that can evaluate quality documentation of the Nutrition Care Process (NCP) encounter, including progress on outcomes is lacking. The aim of the NCP Quality Evaluation and Standardization Tool (QUEST) validation study is to revise an existing NCP audit tool and evaluate it when used within US Veterans Affairs in all clinical care settings. Six registered dietitian nutritionists revised an existing NCP audit tool. The revised tool (NCP-QUEST) was analyzed for clarity, relevance, and reliability. Eighty-five documentation notes (44 initial, 41 reassessment) were received from eight volunteer Veterans Affairs sites. Five of six registered dietitian nutritionists participated in the interrater reliability testing blinded to each other's ratings; and two registered dietitian nutritionists participated in intrarater reliability reviewing the same notes 6 weeks later blinded to the original ratings. Results showed moderate levels of agreement in interrater reliability (Krippendorff's α = .62 for all items, .66 for total score, and .52 for quality category rating). Intrarater reliability was excellent for all items (α = .86 to .87 for all items; .91 to .94 for total score and.74 to .89 for quality category rating). The NCP-QUEST has high content validity (Content Validity Index = 0.78 for item level, and 0.9 for scale level) after two cycles of content validity review. The tool can facilitate critical thinking, improved linking of NCP chains, and is a necessary foundation for quality data collection and outcomes management. The NCP-QUEST tool can improve accuracy and confidence in charting.

Mapping U.S. Food System Localization Potential: The Impact of Diet on Foodsheds.

In the long term, food systems must heed natural resource limits. Localized production and dietary changes are often suggested as potential solutions. However, no U.S. analyses fully evaluate the feasibility to scale localization across a range of diets. We therefore modeled the biophysical capacity for regional food systems based on agricultural land area and productivity, population, and 7 diet scenarios ranging in meat-intensity, from current consumption to vegan. We estimated foodshed size, colloquially known as "food miles" for 378 U.S. metropolitan centers, in a hypothetical nationwide closed system that prioritizes localized food. We found that foodshed size (weighted average distance traveled) for three land types ranged from 351-428 km (cultivated cropland), 80-492 km (perennial forage cropland), and 117-799 km (grazing land). Localized potential varies regionally: foodsheds are generally larger in the populous Northeast, Southeast, and Southwest than in the Northwest and the center of the country. However, depending on consumption of animal-based foods, a sizable proportion of the population could meet its food needs within 250km: from 35%-53% (cultivated cropland), 39%-94% (perennial forage cropland, 100% for vegan), and 26%-88% (grazing land, 100% for ovolacto-vegetarian and vegan). All seven scenarios leave some land unused. This reserve capacity might be used to supply food to the global market, grow bioenergy crops, or for conservation.

Sustainability of Clinical Benefits Gained During a Multidisciplinary Diabetes Shared Medical Appointment After Patients Return to Usual Care.

IN BRIEF This study examined whether clinical benefits gained while participating in interdisciplinary diabetes shared medical appointments (SMAs) of finite duration (three to four monthly visits) are sustained after patients return to usual care. There are currently no publications confirming sustained clinical benefits beyond 9 months after SMA discharge without continued booster sessions to maintain benefits. At the end of the study, it was confirmed that both diabetes and cardiovascular benefits gained during multidisciplinary diabetes SMAs were sustained after patients were discharged to usual care without booster sessions for up to 3 years. The only exceptions were a statistically significant decrease in diastolic blood pressure at each yearly time point and a decrease in the percentage of patients meeting an A1C goal of <9% at year 2.

Effect of liraglutide on dietary lipid-induced insulin resistance in humans.

AIMS: To test whether liraglutide suppresses postprandial elevations in lipids and thus protects against high saturated fatty acid (SFA) diet-induced insulin resistance. METHODS: In a randomized placebo-controlled crossover study, 32 participants with normal or mildly impaired glucose tolerance received liraglutide and placebo for 3 weeks each. Insulin suppression tests (IST) were conducted at baseline and after a 24-hour SFA-enriched diet after each treatment. Plasma glucose, insulin, triglycerides and non-esterified fatty acids (NEFA) were measured over the initial 8 hours (breakfast and lunch) on the SFA diet. A subset of participants underwent ex vivo measurements of insulin-mediated vasodilation of adipose tissue arterioles and glucose metabolism regulatory proteins in skeletal muscle. RESULTS: Liraglutide reduced plasma glucose, triglycerides and NEFA concentrations during the SFA diet (by 50%, 25% and 9%, respectively), and the SFA diet increased plasma glucose during the IST (by 36%; all P < .01 vs placebo). The SFA diet-induced impairment of vasodilation on placebo (-9.4% vs baseline; P < .01) was ameliorated by liraglutide (-4.8%; P = .1 vs baseline). In skeletal muscle, liraglutide abolished the SFA-induced increase in thioredoxin-interacting protein (TxNIP) expression (75% decrease; P < .01 vs placebo) and increased 5'AMP-activated protein kinase (AMPK) phosphorylation (50% vs -3%; P = .04 vs placebo). CONCLUSIONS: Liraglutide blunted the SFA-enriched diet-induced peripheral insulin resistance. This effect may be related to improved microvascular function and modulation of TxNIP and AMPK pathways in skeletal muscle.

A human model of dietary saturated fatty acid induced insulin resistance.

BACKGROUND: Increased consumption of high-fat diets is associated with the development of insulin resistance and type 2 diabetes. Current models to study the mechanisms of high-fat diet-induced IR in humans are limited by their long duration or low efficacy. In the present study we developed and characterized an acute dietary model of saturated fatty acid-enriched diet induced insulin resistance. METHODS: High caloric diets enriched with saturated fatty acids (SFA) or carbohydrates (CARB) were evaluated in subjects with normal and impaired glucose tolerance (NGT or IGT). Both diets were compared to a standard eucaloric American Heart Association (AHA) control diet in a series of crossover studies. Whole body insulin resistance was estimated as steady state plasma glucose (SSPG) concentrations during the last 30min of a 3-h insulin suppression test. RESULTS: SSPG was increased after a 24-h SFA diet (by 83±74% vs. control, n=38) in the entire cohort, which was comprised of participants with NGT (92±82%, n=22) or IGT (65±55%, n=16) (all p<0.001). SSPG was also increased after a single SFA breakfast (55±32%, p=0.008, n=7). The increase in SSPG was less pronounced after an overnight fast following a daylong SFA diet (24±31%, p=0.04, n=10), and further attenuated 24h after returning to the control diet (19±35%, p=0.09, n=11). SSPG was not increased after a 24-h CARB diet (26±50%, p=0.11, n=12). CONCLUSIONS: A short-term SFA-enriched diet induced whole body insulin resistance in both NGT and IGT subjects. Insulin resistance persisted overnight after the last SFA meal and was attenuated by one day of a healthy diet. This model offers opportunities for identifying early mechanisms and potential treatments of dietary saturated fat induced insulin resistance.
