Evaluation of methods used to verify nasogastric feeding tube placement in hospitalized infants and children - A follow-up study.

BACKGROUND: Nasogastric (NG) feeding tubes are used to deliver nutrition, hydration, and medications to hospitalized infants and children but the ongoing use of non-evidence-based practice (EBP) methods to confirm NG tube (NGT) placement has been associated with adverse patient events. METHODS: A study was undertaken to ascertain if practice changes have occurred since findings from a previous study were published by the New Opportunities for Verification of Enteral tube Location (NOVEL) project. The NOVEL project was an initiative of the American Society of Parenteral and Enteral Nutrition (ASPEN). A survey was distributed to member organizations participating in the NOVEL project. Respondents were also asked if and when a change in practice occurred in the policy for NGT placement verification, if there was variation within the institutional units and if there were barriers to practice change. FINDINGS: Respondents were primarily nurses (205/245) from 166 institutions that provided care to combined adult/pediatric/neonatal (122/166) patients. Respondents indicated a radiograph (64%) or pH measurement (24%) were best practice but in actual practice 42% use pH measurement and 23% use a radiograph to verify NGT placement. There was variability within institutions, with the Neonatal Intensive Care Unit (NICU) most often using aspiration and direct eye visualization to verify placement and the other units within the institutions using EBP method(s). DISCUSSION: Comparing these results to previous work by the NOVEL project shows an increase toward the use of EBP method(s) to verify NGT placement verification. APPLICATION TO PRACTICE: This study demonstrates variation within units at the same facility using methods unsupported by the literature, demonstrating that many centers still rely on non-EBP methods of NG placement confirmation, despite cautions issued by many major healthcare organizations.

Investing in human development and building state resilience in fragile contexts: A case study of early nutrition investments in Burkina Faso.

Maternal and early malnutrition have negative health and developmental impacts over the life-course. Consequently, early nutrition support can provide significant benefits into later life, provided the later life contexts allow. This study examines the limits of siloed investments in nutrition and illustrates how ignoring life-course contextual constraints limits human development benefits and exacerbates inequality, particularly in fragile contexts. This case study focuses on Burkina Faso, a country with high rates of early malnutrition and a fragile state. We modelled the impact of scaling up 10 nutrition interventions to 80% coverage for a single year cohort on stunting, nationally and sub-nationally, using the Lives Saved Tool (LiST), and the consequent impact on earnings, without and with a complementary cash-transfer in later life. The impact on earnings was modelled utilising the well-established pathway between early nutrition, years of completed schooling and, consequent adult earnings. Productivity returns were estimated as the present value of increased income over individuals' working lives, then compared to estimates of the present value of providing the cost of nutrition interventions and cash-transfers. The cost benefit ratio at the national level for scaled nutrition alone is 1:1. Sub-nationally the worst-off region yields the lowest ratio < 0.2 for every dollar spent. The combination of nutrition and cash-transfers national cost benefit is 1:12, still with regional variation but with great improvement in the poorest region. This study shows that early nutrition support alone may not be enough to address inequality and may add to state fragility. Taking a life-course perspective when priority-setting in contexts with multiple constraints on development can help to identify interventions that maximizing returns, without worsening inequality.

An ontology of mechanisms of action in behaviour change interventions.

Background: Behaviour change interventions influence behaviour through causal processes called "mechanisms of action" (MoAs). Reports of such interventions and their evaluations often use inconsistent or ambiguous terminology, creating problems for searching, evidence synthesis and theory development. This inconsistency includes the reporting of MoAs. An ontology can help address these challenges by serving as a classification system that labels and defines MoAs and their relationships. The aim of this study was to develop an ontology of MoAs of behaviour change interventions. Methods: To develop the MoA Ontology, we (1) defined the ontology's scope; (2) identified, labelled and defined the ontology's entities; (3) refined the ontology by annotating (i.e., coding) MoAs in intervention reports; (4) refined the ontology via stakeholder review of the ontology's comprehensiveness and clarity; (5) tested whether researchers could reliably apply the ontology to annotate MoAs in intervention evaluation reports; (6) refined the relationships between entities; (7) reviewed the alignment of the MoA Ontology with other relevant ontologies, (8) reviewed the ontology's alignment with the Theories and Techniques Tool; and (9) published a machine-readable version of the ontology. Results: An MoA was defined as "a process that is causally active in the relationship between a behaviour change intervention scenario and its outcome behaviour". We created an initial MoA Ontology with 261 entities through Steps 2-5. Inter-rater reliability for annotating study reports using these entities was α=0.68 ("acceptable") for researchers familiar with the ontology and α=0.47 for researchers unfamiliar with it. As a result of additional revisions (Steps 6-8), 23 further entities were added to the ontology resulting in 284 entities organised in seven hierarchical levels. Conclusions: The MoA Ontology extensively captures MoAs of behaviour change interventions. The ontology can serve as a controlled vocabulary for MoAs to consistently describe and synthesise evidence about MoAs across diverse sources.

A Transdisciplinary Approach to Address Climate Change Adaptation for Human Health and Well-Being in Africa.

The health sector response to dealing with the impacts of climate change on human health, whether mitigative or adaptive, is influenced by multiple factors and necessitates creative approaches drawing on resources across multiple sectors. This short communication presents the context in which adaptation to protect human health has been addressed to date and argues for a holistic, transdisciplinary, multisectoral and systems approach going forward. Such a novel health-climate approach requires broad thinking regarding geographies, ecologies and socio-economic policies, and demands that one prioritises services for vulnerable populations at higher risk. Actions to engage more sectors and systems in comprehensive health-climate governance are identified. Much like the World Health Organization's 'Health in All Policies' approach, one should think health governance and climate change together in a transnational framework as a matter not only of health promotion and disease prevention, but of population security. In an African context, there is a need for continued cross-border efforts, through partnerships, blending climate change adaptation and disaster risk reduction, and long-term international financing, to contribute towards meeting sustainable development imperatives.

Pediatric Nasogastric Tubes in the Home: Recommendations for Practice.

One of the dilemmas facing home healthcare nurses is the placement of a nasogastric tube (NGT) in the home setting coupled with being assured and confident that the NGT tip is in the correct position, that is, the stomach. There are very limited data to address the issue of management of an NGT in the home care setting with even less guidance for the pediatric population. Therefore, home healthcare nurses must use agency policy and procedures coupled with their own education, knowledge, experience, and skills when performing this procedure. These may vary from agency to agency, thus providing inconsistencies in teaching and techniques.

Use of Temporary Enteral Access Devices in Hospitalized Neonatal and Pediatric Patients in the United States.

BACKGROUND: Temporary enteral access devices (EADs), such as nasogastric (NG), orogastric (OG), and postpyloric (PP), are used in pediatric and neonatal patients to administer nutrition, fluids, and medications. While the use of these temporary EADs is common in pediatric care, it is not known how often these devices are used, what inpatient locations have the highest usage, what size tube is used for a given weight or age of patient, and how placement is verified per hospital policy. MATERIALS AND METHODS: This was a multicenter 1-day prevalence study. Participating hospitals counted the number of NG, OG, and PP tubes present in their pediatric and neonatal inpatient population. Additional data collected included age, weight and location of the patient, type of hospital, census for that day, and the method(s) used to verify initial tube placement. RESULTS: Of the 63 participating hospitals, there was an overall prevalence of 1991 temporary EADs in a total pediatric and neonatal inpatient census of 8333 children (24% prevalence). There were 1316 NG (66%), 414 were OG (21%), and 261 PP (17%) EADs. The neonatal intensive care unit (NICU) had the highest prevalence (61%), followed by a medical/surgical unit (21%) and pediatric intensive care unit (18%). Verification of EAD placement was reported to be aspiration from the tube (n = 21), auscultation (n = 18), measurement (n = 8), pH (n = 10), and X-ray (n = 6). CONCLUSION: The use of temporary EADs is common in pediatric care. There is wide variation in how placement of these tubes is verified.

The practice of bariatric surgery at academic medical centers.

The growing demand for laparoscopic bariatric surgery has led to an increase in the development of new bariatric surgical practices. Proper hospital facilities and an experienced bariatric surgical team are necessary to ensure optimal patient results. We surveyed academic centers participating in the University HealthSystem Consortium to examine the current practice of bariatric surgery. The survey questioned (1) availability of resources and equipment designed for the morbidly obese, (2) accidents, equipment problems, and workers' compensation relating to the care of bariatric surgical patients, (3) credentialing of bariatric surgeons, and (4) suggestions for improvements in the bariatric surgery program. Twenty-five institutions that perform bariatric surgery responded. Although the majority of institutions noted that they had basic bariatric equipment, some organizations did not have facility resources such as high-weight operating room tables and computed tomography scanners or transfer devices. Twenty-eight percent of institutions reported having accidents or equipment problems and 40% of institutions had workers' compensation claims relating to the care of bariatric patients. With regard to credentialing, 60% of institutions required the surgeons to have performed a minimum number of procedures prior to granting privileges. Suggested improvements included the need for more specialized bariatric equipment, enhancement of the education of all members of the bariatric surgical team, and designation of a bariatric physician who would coordinate care. This survey of bariatric surgery practices at academic medical centers demonstrates that the practice of bariatric surgery could be improved with regard to availability of bariatric equipment and resources and credentialing of surgeons.

Disability as difference and the nursing profession.

Disability viewed as human difference under the broad umbrella of cultural diversity provides new possibilities for nursing to unite and show what it believes and stands for as a profession. Core essentials of professional nurses are considered. As nurse educators challenge traditions that perpetuate barriers to valuing human differences, the profession, those accepted into it, and those served by it will benefit.

Topical wound oxygen therapy in the treatment of severe diabetic foot ulcers: a prospective controlled study.

Diabetic foot ulcers (DFU) are common, difficult-to-treat, and prone to complications. A prospective, controlled study was conducted to: 1) examine the clinical efficacy of a pressurized topical oxygen therapy (TWO(2)) device in outpatients (N = 28) with severe DFU referred for care to a community wound care clinic and 2) assess ulcer reoccurrence rates after 24 months. Seventeen (17) patients received TWO(2) five times per week (60-minute treatment, pressure cycles between 5 and 50 mb) and 11 selected a silver-containing dressing changed at least twice per week (control). Patient demographics did not differ between treatment groups but wounds in the treatment group were more severe, perhaps as a result of selection bias. Ulcer duration was longer in the treatment (mean 6.1 months, SD 5.8) than in the control group (mean 3.2 months, SD 0.4) and mean baseline wound area was 4.1 cm2 (SD 4.3) in the treatment and 1.4 cm2 (SD 0.6) in the control group (P = 0.02). Fourteen (14) of 17 ulcers (82.4%) in the treatment group and five of 11 ulcers (45.5%) in the control group healed after a median of 56 and 93 days, respectively (P = 0.04). No adverse events were observed and there was no reoccurrence at the ulcer site after 24 months' follow-up in either group. Although the absence of randomization and blinding may have under- or overestimated the treatment effect of either group, the significant differences in treatment outcomes confirm the potential benefits of TWO(2) in the management of difficult-to-heal DFUs. Clinical efficacy and cost-effectiveness studies as well as studies to elucidate the mechanisms of action of TWO(2) are warranted.
