A Randomized Controlled Trial of Precision Nutrition Counseling for Service Members at Risk for Metabolic Syndrome.

INTRODUCTION: Metabolic syndrome (MetS) is a threat to the active component military as it impacts health, readiness, retention, and cost to the Military Health System. The most prevalent risk factors documented in service members' health records are high blood pressure (BP), low high-density lipoprotein cholesterol, and elevated triglycerides. Other risk factors include abdominal obesity and elevated fasting blood glucose. Precision nutrition counseling and wellness software applications have demonstrated positive results for weight management when coupled with high levels of participant engagement and motivation. MATERIALS AND METHODS: In this prospective randomized controlled trial, trained registered dietitians conducted nutrition counseling using results of targeted sequencing, biomarkers, and expert recommendations to reduce the risk for MetS. Upon randomization, the treatment arm initiated six weekly sessions and the control arm received educational pamphlets. An eHealth application captured diet and physical activity. Anthropometrics and BP were measured at baseline, 6 weeks, and 12 weeks, and biomarkers were measured at baseline and 12 weeks. The primary outcome was a change in weight at 12 weeks. Statistical analysis included descriptive statistics and t-tests or analysis of variance with significance set at P < .05. RESULTS: Overall, 138 subjects enrolled from November 2019 to February 2021 between two military bases; 107 completed the study. Demographics were as follows: 66% male, mean age 31 years, 66% married, and 49% Caucasian and non-Hispanic. Weight loss was not significant between groups or sites at 12 weeks. Overall, 27% of subjects met the diagnostic criteria for MetS on enrollment and 17.8% upon study completion. High deleterious variant prevalence was identified for genes with single-nucleotide polymorphisms linked to obesity (40%), cholesterol (38%), and BP (58%). Overall, 65% of subjects had low 25(OH)D upon enrollment; 45% remained insufficient at study completion. eHealth app had low adherence yet sufficient correlation with a valid reference. CONCLUSIONS: Early signs of progress with weight loss at 6 weeks were not sustained at 12 weeks. DNA-based nutrition counseling was not efficacious for weight loss.

Ambulatory Care Nurse-Sensitive Indicators: A Scoping Review of the Literature 2006-2021.

BACKGROUND/PURPOSE: Meeting recommendations that nurses should partner in leading health care change is hampered by the lack of ambulatory care nurse-sensitive indicators (ACNSIs). This scoping review was conducted to identify evidence regarding ACNSI identification, development, implementation, and benchmarking. METHODS: Following the PRISMA-ScR reporting guide, we performed PubMed/MEDLINE, CINAHL, and Cochrane Library searches for the period January 2006 to March 2021. RESULTS: Twelve of the 1984 articles from 6 countries met inclusion criteria. All focused on identifying, developing/pilot testing indicators, and included structure, process, and outcome indicators. Seven articles were level II and all were at least grade B quality. Leverage points involved leadership support, automated data extraction infrastructure, and validating links between nurses' roles/actions and patient outcomes. CONCLUSIONS: While high-quality work is ongoing to identify clinically meaningful and feasible ACNSIs, knowledge in this field remains underdeveloped. Prioritizing this work is imperative to address gaps and facilitate national strategic health care goals.

Improving 9.5 Million Lives: Pilot Testing Ambulatory Care Nurse-Sensitive Quality Indicators.

OBJECTIVE: The aim of this study was to evaluate scientific acceptability, feasibility, utility, and value of ambulatory care nurse-sensitive quality indicators (ACNSIs) in military outpatient clinics. BACKGROUND: Optimizing healthcare quality and cost requires scientifically sound metrics. However, ACNSI development and measurement have lagged behind inpatient nurse-sensitive indicators. Validated and reliable ACNSIs are urgently needed to maximize nurses' efforts to improve healthcare quality. METHODS: Two staffing and 4 patient-centered ACNSIs were pilot tested in 5 military clinics over a 6-month period using a mixed-methods design. RESULTS: Reliability and validity were generally acceptable. Most ACNSIs demonstrated feasibility, utility, and value for performance measurement. Challenges to using ACNSIs include absence of standardized administrative and clinical processes, infrastructure, and leadership and technological support. CONCLUSIONS: These ACNSIs show promise as valid performance metrics. Provider- and nurse-level metrics may synergistically improve practice, enhancing the team approach so critical to ambulatory care.

Novel Phototherapy Kiosk Shows Promise as a Treatment Option for Low Vitamin D.

INTRODUCTION: The purpose of this study was to demonstrate the feasibility of a phototherapy kiosk (PK) to engage community adults in health promotion and to stimulate production of circulating 25-hydroxyvitamin (OH)D as effectively as a vitamin D3 oral supplement (OS). Although optimal production of vitamin D comes from sun exposure, ultraviolet B radiation with a wavelength of 290 to 320 nm penetrates exposed skin and may produce vitamin D3 using a PK. MATERIALS AND METHODS: A prospective study was conducted with adults randomized to either six PK treatments or D3 OS for 10 weeks. Serum 25(OH)D was drawn at baseline, 10 weeks, and 14 weeks. Primary outcome was serum 25(OH)D level. Mann-Whitney test was used to assess continuous data and Chi squared test for pairwise comparisons of categorical data. Significance was set at P < .05. RESULTS: With 18% attrition, final sample size was 88; OS, n = 45, PK, n = 43. Sample was mostly female (60%), median age 35 years, with no differences observed between groups for age, race/ethnicity, marital status, military affiliation, or season of enrollment. Median daily intake of calcium and vitamin D was well below the recommended daily allowance for each nutrient, and group. Baseline median serum 25(OH)D levels were similar. By 10 weeks, PK median level was 30 ng/mL (interquartile range [IQR] 25.8-37.0) and OS was 26 ng/mL (IQR 21.5-30.5), P = .02. The difference in 25(OH)D levels persisted at 14 weeks; the PK group returned to baseline, 27 ng/mL (IQR 22.0-32.5), and OS group declined to 21 ng/mL (IQR 17.0-30.0), P = .02. CONCLUSION: Programmed ultraviolet B phototherapy appears to be an efficacious alternative to oral vitamin D supplementation with consistent use.

Clinical Nutrition Research and the COVID-19 Pandemic: A Scoping Review of the ASPEN COVID-19 Task Force on Nutrition Research.

The purpose of this scoping review by the American Society for Parenteral and Enteral Nutrition (ASPEN) Coronavirus Disease 2019 (COVID-19) Nutrition Task Force was to examine nutrition research applicable to the COVID-19 pandemic. The rapid pace of emerging scientific information has prompted this activity to discover research/knowledge gaps. This methodology adhered with recommendations from the Joanna Briggs Institute. There were 2301 citations imported. Of these, there were 439 articles fully abstracted, with 23 main topic areas identified across 24 article types and sourced across 61 countries and 51 specialties in 8 settings and among 14 populations. Epidemiological/mechanistic relationships between nutrition and COVID-19 were reviewed and results mapped to the Population, Intervention, Comparator, Outcome, and Time (PICO-T) questions. The aggregated data were analyzed by clinical stage: pre-COVID-19, acute COVID-19, and chronic/post-COVID-19. Research gaps were discovered for all PICO-T questions. Nutrition topics meriting urgent research included food insecurity/societal infrastructure and transcultural factors (pre-COVID-19); cardiometabolic-based chronic disease, pediatrics, nutrition support, and hospital infrastructure (acute COVID-19); registered dietitian nutritionist counseling (chronic/post-COVID-19); and malnutrition and management (all stages). The paucity of randomized controlled trials (RCTs) was particularly glaring. Knowledge gaps were discovered for PICO-T questions on pediatrics, micronutrients, bariatric surgery, and transcultural factors (pre-COVID-19); enteral nutrition, protein-energy requirements, and glycemic control with nutrition (acute COVID-19); and home enteral and parenteral nutrition support (chronic/post-COVID-19). In conclusion, multiple critical areas for urgent nutrition research were identified, particularly using RCT design, to improve nutrition care for patients before, during, and after COVID-19.

A Prospective Cohort Study of Vitamin D Supplementation in AD Soldiers: Preliminary Findings.

PURPOSE: To explore response to vitamin D supplementation in active duty (AD) warfighters and translate findings into evidence-based health policy. BACKGROUND: Soldiers are at risk for musculoskeletal injuries and metabolic dysfunction that impact physical performance and military readiness; the link with low vitamin D status is unclear. METHODS: This prospective trial enrolled 152 soldiers; baseline 25 hydroxyvitamin (OH) D level determined assignment to a no-treatment control (CG) or treatment group (TG) receiving a vitamin D3 supplement for 90 days. Symptoms, diet, sun exposure, and blood biomarkers obtained at baseline (T1) and 3 months (T2). RESULTS: Cohort was predominantly white (58%) with a significant difference in racial distribution for vitamin D status. Mean (SD) 25(OH)D levels were 37.8 (5.6) ng/mL, 22.2 (5.0) ng/mL, and 22.9 (4.7) ng/mL for the CG, low dose TG, and high-dose TG at T1, respectively. Following three months of treatment, one-way ANOVA indicated a statistically significant difference between groups (F5,246 = 44.37; p < 0.0001). Vitamin D intake was 44% of Recommended Dietary Allowance throughout the first phase of the trial. Patient-Reported Outcomes Measurement Information System scores improved in TG for fatigue and sleep, p < 0.01. CONCLUSIONS: Vitamin D deficiency is widespread in AD soldiers. Clinicians must intervene early in preventable health conditions impacting warfighter performance and readiness and recommend appropriate self-care strategies.

Immunonutrition in Critical Illness: What Is the Role?

Acute illness-associated malnutrition leads to muscle wasting, delayed wound healing, failure to wean from ventilator support, and possibly higher rates of infection and longer hospital stays unless appropriate metabolic support is provided in the form of nutrition therapy. Agreement is still lacking about the value of individual immune-modulating substrates for specific patient populations. However, it has long been agreed that there are 3 primary targets for these substrates: 1) mucosal barrier function, 2) cellular defense function, and 3) local and systemic inflammation. These targets guide the multitude of interventions necessary to stabilize and treat the hypercatabolic intensive care unit patient, including specialized nutrition therapy. The paradigm shift that occurred 30 years ago created a unique role for nutrition as an agent to support host defense mechanisms and prevent infectious complications in the critically ill patient. This overview of immunonutrition will discuss the evidence for its role in critical illness today.

Critical Care in the Military Health System: A Survey-Based Summary of Critical Care Services.

Introduction: Critical care is an important component of in-patient and combat casualty care, and it is a major contributor to U.S. healthcare costs. Regular exposure to critically ill and injured patients may directly contribute to wartime skills retention for military caregivers. Data describing critical care services in the Military Health System (MHS), however, is lacking. This study was undertaken to describe MHS critical care services, their resource utilization, and differences in care practices amongst military treatment facilities (MTFs). Materials and Methods: Twenty-six MTFs representing 38 adult critical care services or intensive care units (ICUs) were surveyed. The survey collected information about organizational structure, resourcing, and unit characteristics at the time of a concurrent 24-h point-prevalence survey designed to describe patient characteristics and staffing in these facilities. The survey was anonymous and protected health information was not collected. We analyzed the data according to high capacity centers (HCCs) (≥200 beds) and low capacity centers (LCCs) (<200 beds). Differences between HCCs and LCCs were compared using Fisher's exact test. Results: Seventeen MTFs (7 HCCs and 10 LCCs), representing 27 ICUs, responded to the survey. This was a 65% response rate for MTFs and a 71% response rate for services/ICUs. HCCs reported more closed vs. open ICUs; more dedicated critical care services (i.e., medical and surgical ICUs vs. mixed ICUs); fewer respiratory therapists available, but more with certification; more total nursing staff and more critical care certified nurses; the use of subjectively more effective protocols (10.5 vs. 6.7 protocols/unit or service); higher utilization of an ICU daily rounds checklist (65% vs. 0%); and less consistency of clinician type participation during multidisciplinary rounds. ICU leadership structure was similar among the institutions. The majority of respondents were unable to provide summary APACHE II scores, but HCCs were more likely to submit this information than LCCs. Most centers perform multidisciplinary rounds daily, but they are more likely to be run by a physician credentialed in critical care at HCCs (85% vs. 59%, p < 0.05). 67% of respondents reported mortality rates <5%. The two services that reported mortality rates greater than 10% were both LCCs. Conclusion: This is the first comprehensive report about MHS critical care services. Despite notable variability in data reporting, an important finding itself, this study highlights notable differences in organizational structure and resourcing between HCCs and LCCs within the MHS. The clinical implication of these differences (i.e., impact on patient outcomes) of these differences require further study. Better understanding of MHS critical care services may improve enterprise decision-making about these services which could ultimately improve care of combat casualties.

Critical Care in the Military Health System: A 24-h Point Prevalence Study.

Background: Healthcare expenditures are a significant economic cost with critical care services constituting one of its largest components. The Military Health System (MHS) is the largest, global healthcare system of its kind. In this project, we sought to describe critical care services and the patients who receive them in the MHS. Methods: We surveyed 26 military treatment facilities (MTFs) representing 38 critical care services or intensive care units (ICUs). MTFs with multiple ICUs and critical care services responded to the survey as services (e.g., surgical or medical ICU service), whereas MTFs with only one ICU responded as a unit and gave information about all types of patients (i.e., medical and surgical). Our survey was divided into an administrative portion and a 24-h point prevalence survey of patients and patient care. The administrative portion is reported separately in this journal. The 24-h point prevalence survey collected information about all patients present in, admitted to, or discharged from participating services/units during the same 24-h period in December 2014. The survey was anonymous and protected health information was not collected. Findings: Sixteen MTFs (69%) and 27 ICU services/units (71%) returned the point prevalence survey. MTFs with >200 beds (n = 3, 22%) were categorized as "high capacity centers" (HCCs) whereas those with ≤200 beds (n = 13, 78%) were characterized as low capacity centers (LCCs). Two MTFs (one HCC and one LCC) returned only administrative data. The remaining 16 MTFs reported data about 151 patients. In all, 100 (67%) of the patients were at three HCCs during this study period. One HCC accounted for 39% (59 patients) of all patient care during this study. Most patients were cared for in mixed medical/surgical ICUs (34.4%), followed by medical (21.2%), surgical (18.5%), trauma (11.9%), cardiac (7.9%), and burn (6.0%) ICUs. The most common medical indication for admission was cardiac followed by general medical. The most common surgical indications for admission were trauma, other, and cardiothoracic surgery. The average APACHE II score of all patients across both LCCs and HCCs was 11 ± 8.1 (8 ± 7.8 vs. 13 ± 7.7 p = 0.008). The lower acuity of patients in this study is reflected in a high turnover rate, low rate of arterial and central line placements (33%), and low rates of life support (all types, 30%; mechanical ventilation only, 21.2%; noninvasive mechanic ventilation only, 7.9%; and vasoactive medications, 6.6%). Thirty-five (23.2%) patients within the study were affected by a total of 57 complications. The three most common complications experienced were acute kidney injury, bleeding, and sepsis. Discussion: This is the first detailed report about MHS critical care services and the patients receiving care. It describes a low acuity ICU patient population, concentrated at larger MTFs. This study highlights the need for the establishment of a system that allows for the continuous collection of high priority information about clinical care in the MHS in order to facilitate implementation of standardized protocols and process improvements.

Twenty years of staffing, practice environment, and outcomes research in military nursing.

BACKGROUND: Two decades ago, findings from an Institute of Medicine (IOM) report sparked the urgent need for evidence supporting relationships between nurse staffing and patient outcomes. PURPOSE: This article provides an overview of nurse staffing, practice environment, and patient outcomes research, with an emphasis on findings from military studies. Lessons learned also are enumerated. METHOD: This study is a review of the entire Military Nursing Outcomes Database (MilNOD) program of research. DISCUSSION: The MilNOD, in combination with evidence from other health care studies, provides nurses and leaders with information about the associations between staffing, patient outcomes, and the professional practice environment of nursing in the military. Leaders, therefore, have useful empirical evidence to make data-driven decisions. The MilNOD studies are the basis for the current Army nursing dashboard, and care delivery framework, called the Patent CaringTouch System. CONCLUSION: Future research is needed to identify ideal staffing based on workload demands, and provide leaders with factors to consider when operationalizing staffing recommendations.

Health promotion research in active duty army soldiers: The road to a fit and ready force.

BACKGROUND: In the last decade the Military Health System has changed its paradigm to focus on health promotion and disease prevention. PURPOSE: This paper reviews a decade of research exploring the effects of military life on nutritional status and bone health of Army soldiers. METHOD: Descriptive and experimental approaches have assessed occupational demands on soldiers in variable environments that require optimal nutrition status and physical health. DISCUSSION: The prevalence of overweight and obesity in the military has risen dramatically and the implications for health, readiness, productivity, and cost demands attention. The related nutritional deficits such as suboptimal vitamin D status likely contribute to musculoskeletal injuries which have a greater impact on the performance and readiness of soldiers than any other medical condition in peacetime or conflict. CONCLUSION: The greatest challenge in our system for health is optimizing the performance of all soldiers while minimizing health risks and long-term disability resulting from occupational hazards, particularly those inherent to war.

Improving the Patient Experience by Implementing an ICU Diary for Those at Risk of Post-intensive Care Syndrome.

The critical care literature in the US has recently brought attention to the impact an ICU experience can have long after the patient survives critical illness, particularly if delirium was present. Current recommendations to mitigate post-intensive care syndrome (PICS) are embedded in patient and family-centered care and aim to promote family presence in the ICU, provide support for decision-making, and enhance communication with the health-care team. Evidence-based interventions are few in number but include use of an ICU diary to minimize the psychological and emotional sequelae affecting patients and family members in the months following the ICU stay. In this paper we describe our efforts to implement an ICU diary and solicit feedback on its role in fostering teamwork and communication between patients, family members, and ICU staff. Next steps will involve a PICS follow-up clinic where trained staff will coordinate specialty referrals and perform long-term monitoring of mental health and other quality of life outcomes.

A Randomized Controlled Trial of Nurse Coaching vs. Herbal Supplementation for Weight Reduction in Soldiers.

The number of overweight and obese service members has tripled since the beginning of Overseas Contingency Operations.1 Overwhelming evidence suggesting links between obesity and increased risk for conditions such as musculoskeletal injuries, type II diabetes, and cardiovascular disease,2 poses a threat to the strength and performance of our current and future fighting force. OBJECTIVE: The purpose of the study was to test nurse health coaching (NHC) and/or herbal supplementation for weight reduction in Soldiers during a 12-week intervention. METHODS: Body composition, biomarkers, adherence, and motivation were measured at three time points. The NHC provided a weekly scripted interaction. Change scores were compared across study groups using general linear models. RESULTS: Sample demographics (N = 435): mean age 30 ± 8.2 years, 73.4% men, predominantly white (70.1%) and non-Hispanic (80%), 71% married, and 91% enlisted. Results represent the 3 NHC groups compared to control group. Beneficial intervention effects were observed for heel bone mineral density (d = 0.3), 25-Hydroxyvitamin D (d = 0.43), and fasting blood sugar (d = -0.4), but were not significant following application of a 10% false discovery rate. There were no significant findings for any other comparisons. CONCLUSION: Weight loss proved difficult for all groups; there was no advantage of NHC over an herbal supplement as adjuncts to Army MOVE! for weight reduction. Highly motivated Soldiers were unable to sustain weight loss or body composition changes.

Association of Temporal Variations in Staffing With Hospital-Acquired Pressure Injury in Military Hospitals.

To more precisely evaluate the effects of nurse staffing on hospital-acquired pressure injury (HAPI) development, data on nursing care hours per patient day (NCHPPD), nursing skill mix, patient turnover (i.e., admissions, transfers, and discharges), and patient acuity were merged with patient information from pressure injury prevalence surveys that were collected annually for the Military Nursing Outcomes Database (MilNOD) project. The MilNOD included staffing and adverse events from 56 medical-surgical, stepdown, and critical care units in 13 military hospitals over a 4-year-period. Data on 1,643 patients were analyzed with Cox proportional hazards models and generalized estimating equations. Staffing was not associated with pressure injuries in stepdown or critical care patients. However, among the 1,104 medical-surgical patients, higher licensed practical nurse (LPN) nursing care hours per patient day (NCHPPD) 3 days and 1 week prior to the HAPI discovery date were associated with fewer HAPI (HR 0.27, p < .001), after controlling for patient age, Braden mobility score, and albumin level. Neither total staff number, nor RN NCHPPD, nor the proportion of staff who were RNs (RN skill mix) were associated with HAPI. These findings suggest that on military medical-surgical units, LPNs play a major role in HAPI prevention. Although the national trend in acute care is to staff hospital units with more RNs and patient care technicians, and fewer LPNs, hospitals should reconsider LPNs as valuable members of the nursing care team. © 2016 Wiley Periodicals, Inc.

Telehealth Coaching: Impact on Dietary and Physical Activity Contributions to Bone Health During a Military Deployment.

PURPOSE: To examine the difference in bone health and body composition via blood biomarkers, bone mineral density, anthropometrics and dietary intake following deployment to Afghanistan among soldiers randomized to receive telehealth coaching promoting nutrition and exercise. METHODS: This was a prospective, longitudinal, cluster-randomized, controlled trial with repeated measures in 234 soldiers. Measures included heel bone scan for bone mineral density, blood biomarkers for bone formation, resorption, and turnover, body composition via Futrex, resting metabolic rate via MedGem, physical activity using the Baecke Habitual Physical Activity Questionnaire, and dietary intake obtained from the Block Food Frequency Questionnaire. RESULTS: There were significant increases in body fat (p = 0.00035), osteocalcin (0.0152), and sports index (p = 0.0152) for the telehealth group. No other statistically significant differences were observed between groups. Vitamin D intake among soldiers was ≤ 35% of the suggested Dietary Reference Intakes for age. CONCLUSIONS: A 9-month deployment to Afghanistan increased body fat, bone turnover, and physical activity among soldiers randomized to receive telehealth strategies to build bone with nutrition and exercise.

Developing a Diary Program to Minimize Patient and Family Post-Intensive Care Syndrome.

A series of evidence-based interventions beginning with an intensive care unit diary and a patient/family educational pamphlet were implemented to address the long-term consequences of critical illness after discharge from the intensive care unit, bundled as post-intensive care syndrome and post-intensive care syndrome-family. An extensive literature review and nursing observations of the phenomenon highlighted the potential for this project to have a favorable impact on patients, their families, and the health care team. The goal of this article is to explain the education of all stakeholders; the introduction of the diary, video, and educational pamphlet; and the evaluation of the acceptance of these interventions. This process began with an informal evaluation of the educational products and overall perception of the usefulness of the diary by patients, family members, and staff. The efforts described contribute to the evidence base supporting diaries as an adjunct to intensive care.

Practical Application of the Revised Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Adult Critically Ill Patient: A Case Study Approach.

BACKGROUND: Nutrition therapy is an essential component of the care plan for critically ill and injured patients. There is consensus that critically ill patients are at risk for malnutrition, and the associated consequences of increased infectious morbidity, multiorgan dysfunction, prolonged hospitalization, and disproportionate mortality can be minimized with specialized enteral and/or parenteral nutrition therapy. METHODS: In this article, we describe 2 case studies that are intended to introduce the nutrition support clinician to key updates in the recently released Guidelines for Provision and Assessment of Nutrition Support Therapy in the Adult Critically Ill Patient: Society of Critical Care Medicine (SCCM) and American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.). RESULTS: The case studies demonstrate a pragmatic approach to nutrition therapy in the intensive care unit (ICU) and are intended to elicit dialogue for timely, appropriate nutrition care at policy meetings, professional conferences, and ICU daily rounds. CONCLUSIONS: While explicitly stated in the formal document, it is worth repeating that the guidelines are directed toward generalized patient populations, but as with any therapeutic intervention in the ICU, nutrition therapy should be tailored to the individual patient. In addition, protocols and procedures should reflect the local institutional culture and meet with approval of critical care clinicians.
