Preimplementation of Critical Care Early Mobility Clinical Decision Support: A Content Validation Study.

Early mobility is a form of critical care rehabilitation ranging from in-bed exercise to ambulation and is known to limit post-intensive-care functional decline. Multiple barriers prevent widespread early mobility implementation. Clinical decision support systems can optimize the decision-making process and overcome barriers to care. However, critical care early mobility clinical decision support does not exist. Our objective was to develop and establish the content validation of the operational definitions for a novel critical care early mobility assessment instrument. Content validation was conducted in two steps: (1) development of operational definitions by the research team and (2) content validation with 10 nurse experts. Quality assessment and suitability of the operational definitions for 30 items, across four safety domains, were assessed using a 7 point-Likert scale. Item content validity index scores ranged from 0.6 to 0.1 after the first validation round. Domains containing items with item content validity index scores less than the lower limit of 0.78 were modified for clarity of language. Item content validity index scores ranged from 0.8 to 1.0, and the scale-level content validity index was 0.93 after the second content validation round. Excellent content validity of the operational definitions was achieved. This is the first methodological step in a larger project to develop clinical decision support for critical care early mobility.

Advanced Practice RN Student Practicum Placements: An Academic Health Center and College of Nursing Collaboration.

Academic health centers are faced with limited resources to navigate placement of advanced practice RN (APRN) students at the same time as APRN programs continue to increase. Clinical practicum sites are in higher demand due to clinical hour increases by accrediting organizations. This article describes a successful approach to the inefficient use of administration and preceptor resources for APRN student practicum placements via an innovative academic health system partnership.

Identifying Comorbid Subtypes of Patients With Acute Respiratory Failure.

BACKGROUND: Patients with acute respiratory failure have multiple risk factors for disability following their intensive care unit stay. Interventions to facilitate independence at hospital discharge may be more effective if personalized for patient subtypes. OBJECTIVES: To identify subtypes of patients with acute respiratory failure requiring mechanical ventilation and compare post-intensive care functional disability and intensive care unit mobility level among subtypes. METHODS: Latent class analysis was conducted in a cohort of adult medical intensive care unit patients with acute respiratory failure receiving mechanical ventilation who survived to hospital discharge. Demographic and clinical medical record data were collected early in the stay. Clinical characteristics and outcomes were compared among subtypes by using Kruskal-Wallis tests and χ2 tests of independence. RESULTS: In a cohort of 934 patients, the 6-class model provided the optimal fit. Patients in class 4 (obesity and kidney impairment) had worse functional impairment at hospital discharge than patients in classes 1 through 3. Patients in class 3 (alert patients) had the lowest magnitude of functional impairment (P < .001) and achieved the earliest out-of-bed mobility and highest mobility level of all subtypes (P < .001). CONCLUSIONS: Acute respiratory failure survivor subtypes identified from clinical data available early in the intensive care unit stay differ in post-intensive care functional disability. Future research should target high-risk patients in early rehabilitation trials in the intensive care unit. Additional investigation of contextual factors and mechanisms of disability is critical to improving quality of life in acute respiratory failure survivors.

Playing your pain away: designing a virtual reality physical therapy for children with upper limb motor impairment.

Children with upper limb motor impairment often undergo repetitive therapeutic physiotherapy sessions to minimize functional disabilities of the affected area. Even though therapeutic processes can improve functional outcomes and minimize persistent disabilities, patients often neglect to participate fully in physical therapies due to the associated procedural pain. Over recent decades, there has been a growing interest in designing non-pharmacological interventions which aim to minimize pain during physical therapies and improve functional outcomes. Via two interrelated studies, we explored the use of virtual reality (VR) as a tool to provide therapeutic physiotherapy for child patients in an out-patient hospital department. We found that VR is an effective solution for children with upper limb motor impairment undergoing painful therapeutic process within a hospital environment. VR can improve functional disabilities, alleviate perceived pain, reduce the perceived difficulty of rehabilitation exercises, increase exercise duration and produce positive emotions towards the therapy.

Rapid Response Systems at a Long-Term Acute Care Hospital.

Rapid Response Systems (RRS) improve patient outcomes at large medical centers. Little is known about how RRS are used in other medical settings. The purpose of this exploratory study was to describe RRS events at a long-term acute care hospital (LTACH). We conducted a retrospective review of 71 RRS event records at an urban 50-bed Midwestern LTACH. Measures included demographic data, triggering mechanisms, contextual factors, mechanism factors, and clinical outcomes. Of patients who experienced a RRS event, median age was 71 (62, 80) years; 52.1% were female; most (n = 49, 69%) were "full code." Most (n = 41, 58%) events occurred during the daytime. The most common trigger was "mental status changes/unresponsiveness." Registered nurses were the most frequent activator (n = 19, 26.8%) and responders (n = 63, 60.6%). Median duration of RRS events was 14 (6, 25) minutes. Most patients stabilized and their condition improved (n = 54, 76.1%). RRS can be expanded and modified to the LTACH population.

Post-intensive care syndrome: A review for the primary care NP.

ABSTRACT: Post-intensive care syndrome is a costly and complicated collection of physical, cognitive, and mental health problems experienced by survivors of critical illness. The primary care NP is uniquely positioned to assess, monitor, manage, and treat patients with this syndrome following hospital discharge.

Decision Support to Improve Critical Care Services Documentation in an Academic Emergency Department.

OBJECTIVES: Critical care services (CCS) documentation affects billing, operations, and research. No studies exist on documentation decision support (DDS) for CCS in the emergency department (ED). We describe the design, implementation, and evaluation of a DDS tool built to improve CCS documentation at an academic ED. METHODS: This quality improvement study reports the prospective design, implementation, and evaluation of a novel DDS tool for CCS documentation at an academic ED. CCS-associated ED diagnoses triggered a message to appear within the physician note attestation workflow for any patient seen in the adult ED. The alert raised awareness of CCS-associated diagnoses without recommending specific documentation practices. The message disappeared from the note automatically once signed. We measured current procedural terminology (CPT) codes 99291 or 99292 (representing CCS rendered) for 8 months before and after deployment to identify CCS documentation rates. We performed state-space Bayesian time-series analysis to evaluate the causal effect of our intervention on CCS documentation capture. We used monthly ED volume and monthly admission rates as covariate time-series for model generation. RESULTS: The study included 92,350 ED patients with an observed mean proportion CCS of 3.9% before the intervention and 5.8% afterward. The counterfactual model predicted an average response of 3.9% [95% CI 3.5-4.3%]. The estimated absolute causal effect of the intervention was 2.0% [95% CI 1.5-2.4%] (p = 0.001). CONCLUSION: A DDS tool measurably increased ED CCS documentation. Attention to user workflows and collaboration with compliance and billing teams avoided alert fatigue and ensures compliance.

Evaluation of early post-natal pig mammary gland development and human breast cancer gene expression.

Breast cancer is the second leading cause of death in women after lung cancer, and only 5% of patients with metastatic breast cancer survive beyond ten years of diagnosis. Considering the heterogeneous subclasses of breast cancer, current cancer models have shortfalls due to copy number variants, and genetic differences of humans and immunocompromised animal models. Preclinical studies indicate stem cell activity in early post-natal mammary development may be reactivated in the human adult as a trigger to initiate cell proliferation leading to breast cancer. The goal of the work reported herein was to compare genetic expression of early development, post-natal pig mammary glands to the literature reported genes implicated in different subclasses of human breast cancer. Differentially expressed genes associated with breast cancer and present in early developing pig samples include NUCB2, ANGPTL4 and ACE. Histological staining confirmed E-cadherin, Vimentin, N-cadherin, and Claudin-1, which are all implicated in malignant cancer. Due to the homology of gene expression patterns in the developing pig mammary gland and reported genes in human breast cancer profiles, this research is worthy of further study to address a potential model using mammary development cues to unravel breast cancer biology.

Immersive virtual reality in children with upper limb injuries: Findings from a feasibility study.

PURPOSE: Children who sustain Upper Limb Injuries (ULIs), including fractures and burns, may undergo intensive rehabilitation. The discomfort of therapy can reduce their compliance, limit their range of motion (ROM) and lead to chronic pain. Virtual Reality (VR) interventions have been found to reduce anticipated and procedural pain.This feasibility study aimed to explore perceptions and impacts of a custom-made, fully immersive Head-Mounted Display VR (HMD-VR) experience within a United Kingdom (UK) National Health Service (NHS) outpatient rehabilitation service for children with ULIs. METHODS: Ten children aged 9-16 in one UK Children's hospital trialled HMD-VR during one rehabilitation session. They, their parents (n = 10), and hospital physiotherapy staff (n = 2) were interviewed about their perceptions of pain, difficulty, enjoyability, therapeutic impacts, benefits, and limitations. Children rated the sessions on enjoyability, difficulty, and pain compared to usual rehabilitation exercises. Physiotherapists were asked to provide range of motion readings. RESULTS: Inductive thematic analysis of interview data generated three themes, 'Escape through Engagement'; 'Enhanced Movement'; and 'Adaptability and Practicality'. Children rated the session as more enjoyable, less difficult and painful than their usual rehabilitation exercises. Findings suggested that HMD-VR was an engaging, enjoyable experience that distracted children from the pain and boredom of therapy. Also, it seemed to enhance the movement they achieved. Participants perceived it was useful for rehabilitation and adaptable to individual needs and other patient groups. Suggestions were made to increase adaptability and build in practical safeguards. CONCLUSION: Findings from this small-scale feasibility study suggested HMD-VR was perceived as usable, acceptable, and effective with potential for further development. Future work could include larger scale trials.

Perspectives, experiences, and opinions precepting advanced practice registered nurse students.

BACKGROUND: Significant growth in advanced practice registered nurse (APRN) student placements for clinical practicums have forced APRN preceptors, hospitals, and clinics to restrict the volume of APRN students they can accommodate. PURPOSE: Describe the experiences and opinions of APRNs regarding their precepting experiences of APRN students in three main areas; placement antecedents, placement postcedents, and preceptor incentives. METHODS: Quality improvement study conducted via electronic survey that contained quantitative short answer and a qualitative open-ended question of APRNs licensed in the State of REDACTED in June, 2019. FINDINGS: A total of 757 surveys were quantitatively analyzed. Qualitative thematic analysis resulted in identifying one overarching theme, the need for shared responsibility and accountability, and six unique primary themes. DISCUSSION: Our findings indicate that APRN preceptors recognize their critical role but lack support and preparation to fully execute academic and profession strategic goals and objectives. There is the need for academic and professional ownership of APRN education at every level.

Computed Tomographic Measures of Funnel-Shaped Lumbar Vertebral Canal and Articular Process Dysplasia Malformations Differ Between German Shepherd and Belgian Malinois Military Working Dogs.

Researchers who study the selection and breeding program criteria for military working dogs aim to help maximize the years of active duty service. Computed tomographic (CT) quantitative phenotyping has been previously described as a method for supporting these research studies. Funnel-shaped lumbar vertebral foramen malformations have been previously described in Labrador retriever military working dogs and proposed to be risk factors for impaired arterial perfusion of nerve tissues during exercise. Articular process dysplasia malformations have been previously described in varying dog breeds and proposed to be risk factors for articular process degenerative joint disease and vertebral foramen stenosis. Aims of this retrospective, cross-sectional study were to describe quantitative CT phenotyping methods for characterizing funnel-shaped lumbar vertebral foramina and articular process dysplasia malformations and to apply these methods in a comparison between groups of German shepherd and Belgian Malinois military working dogs. A military working dog hospital's database was searched for German shepherd and Belgian Malinois dogs aged <6 years that had CT scans of the lumbosacral region during the period of 2008-2016. Observers unaware of CT findings recorded available clinical data for each of the dogs. An observer unaware of clinical data recorded CT measures of funnel-shaped lumbar vertebral foramina and articular process dysplasia malformations for each of dogs and each of the lumbar vertebrae that were available in the scans. A total of 59 dogs were sampled: 41 German shepherd and 18 Belgian Malinois. Articular process dysplasia and funnel-shaped vertebral foramen phenotypic traits were present in both breeds in this sample, with the frequency and quantitative measure of these traits being greater in German shepherd dogs and heavier dogs. Lower weight dogs had a lesser degree of a funnel-shaped foramen at all sampled vertebral locations. A consistent relationship between articular process dysplasia measures and body weight was not seen. Computed tomography measures of funnel shaped vertebral foramina were greater in German shepherd vs. Belgian Malinois dogs at the L7 vertebra (P < 0.01). The CT measures of cranial articular process dysplasia were greater in German shepherd vs. Belgian Malinois dogs at the L4 (P < 0.01) and L5 (P < 0.05) vertebrae.

The Use of a Smartphone App and an Activity Tracker to Promote Physical Activity in the Management of Chronic Obstructive Pulmonary Disease: Randomized Controlled Feasibility Study.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is highly prevalent and significantly affects the daily functioning of patients. Self-management strategies, including increasing physical activity, can help people with COPD have better health and a better quality of life. Digital mobile health (mHealth) techniques have the potential to aid the delivery of self-management interventions for COPD. We developed an mHealth intervention (Self-Management supported by Assistive, Rehabilitative, and Telehealth technologies-COPD [SMART-COPD]), delivered via a smartphone app and an activity tracker, to help people with COPD maintain (or increase) physical activity after undertaking pulmonary rehabilitation (PR). OBJECTIVE: This study aimed to determine the feasibility and acceptability of using the SMART-COPD intervention for the self-management of physical activity and to explore the feasibility of conducting a future randomized controlled trial (RCT) to investigate its effectiveness. METHODS: We conducted a randomized feasibility study. A total of 30 participants with COPD were randomly allocated to receive the SMART-COPD intervention (n=19) or control (n=11). Participants used SMART-COPD throughout PR and for 8 weeks afterward (ie, maintenance) to set physical activity goals and monitor their progress. Questionnaire-based and physical activity-based outcome measures were taken at baseline, the end of PR, and the end of maintenance. Participants, and health care professionals involved in PR delivery, were interviewed about their experiences with the technology. RESULTS: Overall, 47% (14/30) of participants withdrew from the study. Difficulty in using the technology was a common reason for withdrawal. Participants who completed the study had better baseline health and more prior experience with digital technology, compared with participants who withdrew. Participants who completed the study were generally positive about the technology and found it easy to use. Some participants felt their health had benefitted from using the technology and that it assisted them in achieving physical activity goals. Activity tracking and self-reporting were both found to be problematic as outcome measures of physical activity for this study. There was dissatisfaction among some control group members regarding their allocation. CONCLUSIONS: mHealth shows promise in helping people with COPD self-manage their physical activity levels. mHealth interventions for COPD self-management may be more acceptable to people with prior experience of using digital technology and may be more beneficial if used at an earlier stage of COPD. Simplicity and usability were more important for engagement with the SMART-COPD intervention than personalization; therefore, the intervention should be simplified for future use. Future evaluation will require consideration of individual factors and their effect on mHealth efficacy and use; within-subject comparison of step count values; and an opportunity for control group participants to use the intervention if an RCT were to be carried out. Sample size calculations for a future evaluation would need to consider the high dropout rates.

Methodology to analyze gene expression patterns of early mammary development in pig models.

In mammary gland development, normal stem cell activity occurs in the embryonic stage and postnatally. Research supports that certain breast cancers contain a small sub-population of cells that mimic stem-like activity. It is believed stem cell activation in the mutated mature human mammary tissue is what drives quiescent epithelial cells to convert to mesenchymal states initiating migration, invasion, and metastasis in breast cancer. The goal of the work reported herein was to investigate early mammary development gene expression in the postnatal pig using fine needle biopsy methods in order to establish a reliable model for human breast cancer detection. Tissue samples were collected from pig mammary glands beginning at Day 11 of age through Day 39 in order to capture early postnatal-growth gene expression. Based on the initial clustering analysis, two distinct clusters of gene expression profiles occurred before and after Day 25 of mammary development. Gene set enrichment analysis (GSEA) ontology indicated the cellular processes that changed after Day 25, and many of these processes were implicated in epithelial-mesenchymal transition (EMT) signaling events. Gene expression in the postnatal pig was compared with the Epithelial-Mesenchymal Transition gene database (dbEMT) confirming the presence of EMT activity in this early developmental program. Information from this study will provide insight into early postnatal mammary gland development. In addition, mechanisms exploited by mutated mammary epithelial cells leading to cancer initiation and growth may be detected considering that mutated mammary epithelial cells can reactivate early developmental signals.

A latent class analysis of prolonged mechanical ventilation patients at a long-term acute care hospital: Subtype differences in clinical outcomes.

RATIONALE: Patients on prolonged mechanical ventilation (PMV) at Long-Term Acute Care Hospital's (LTACHs) are clinically heterogeneous making it difficult to manage care and predict clinical outcomes. OBJECTIVES: Identify and describe subgroups of patients on PMV at LTACHs and examine for group differences. METHODS: Latent class analysis was completed on data obtained during medical record review at Midwestern LTACH. MAIN RESULTS: A three-class solution was identified. Class 1 contained young, obese patients with low clinical and co-morbid burden; Class 2 contained the oldest patients with low clinical burden but multiple co-morbid conditions; Class 3 contained patients with multiple clinical and co-morbid burdens. There were no differences in LTACH length of stay [F(2,246) = 2.243, p = 0.108] or number of ventilator days [F(2,246) = 0.641, p = 0.528]. Class 3 patients were less likely to wean from mechanical ventilation [χ2(2, N = 249) = 25.48, p < 0.001] and more likely to die [χ2(2, N = 249) = 23.68, p < 0.001]. CONCLUSION: Patient subgroups can be described that predict clinical outcomes. Class 3 patients are at higher risk for poor clinical outcomes when compared to patients in Class 1 or Class 2.

Cluster Analysis in Nursing Research: An Introduction, Historical Perspective, and Future Directions.

The use of cluster analysis in the nursing literature is limited to the creation of classifications of homogeneous groups and the discovery of new relationships. As such, it is important to provide clarity regarding its use and potential. The purpose of this article is to provide an introduction to distance-based, partitioning-based, and model-based cluster analysis methods commonly utilized in the nursing literature, provide a brief historical overview on the use of cluster analysis in nursing literature, and provide suggestions for future research. An electronic search included three bibliographic databases, PubMed, CINAHL and Web of Science. Key terms were cluster analysis and nursing. The use of cluster analysis in the nursing literature is increasing and expanding. The increased use of cluster analysis in the nursing literature is positioning this statistical method to result in insights that have the potential to change clinical practice.

Bacterial and Viral Products Affect Differential Pattern Recognition Receptor Activation of Chicken Thrombocytes Evidenced through RNA Sequencing.

It is now well understood that thrombocytes (nucleated platelets) express TLRs and respond to both bacterial and viral products. Release of proinflammatory molecules can be expected following relatively short exposure times to LPS, lipoteichoic acid (LTA), thymidine homopolymer phosphorothioate oligonucleotide [Poly(dT)], and polyinosinic-polycytidylic acid [Poly(I:C)]. This study reports the varied expressions of genes encoded for components of the TLR, nucleotide binding oligomerization domain-like receptor, and retinoic acid-inducible gene RIG-like receptor signaling pathways in response to the TLR ligands listed above. Highly sensitive RNA-sequencing technologies were used to analyze the complete transcriptome of thrombocytes treated with all four microbial products for a period of 1 h. A total of 14,326 gene transcripts were found in chicken thrombocytes across all ligand exposures. After 1 h of stimulation with ligands, 87, 138, 1013, and 22 genes were upregulated for LTA, LPS, Poly(dT), and Poly(I:C), and 12, 142, 249, and 16 genes were downregulated for LTA, LPS, Poly(dT), and Poly(I:C), respectively, with at least a 1-fold change relative to unexposed thrombocytes. Summarizations of biological processes, protein classes, and biochemical pathways reveal the role of chicken thrombocytes in proinflammatory responses linked to key signaling pathways. TLR, nucleotide binding oligomerization domain-like receptor, and retinoic acid-inducible gene RIG-like receptor pathways were mapped based on the transcriptome results with gene expression for common signal and proinflammatory mediators highlighted. The information reported in this study is useful for defining a limited set of proinflammatory molecules to evaluate in cases of either bacterial or viral disease monitoring.

Mobilization of prolonged mechanical ventilation patients: An integrative review.

Mobilization of mechanical ventilation patients has broadened to include patients requiring prolonged mechanical ventilation (PMV). A previous systematic review outlined methodological flaws in the literature. The purpose of this integrative review is to evaluate existing publications to determine if mobilization interventions in PMV patients improve physical function, weaning rates, pulmonary mechanics, and hospital outcomes. An electronicsearch covering 2005-2016, included five bibliographic databases: CINHAL, PubMed, PEDro, EMBASE, and Web of Science. Key terms: PMV, mobilization, therapy, and rehabilitation. Eight research studies were identified; 3 RCT's, 3 medical records reviews, 1 prospective cohort, and 1 undefined prospective interventional. Improvements in functional status, shorter duration of mechanical ventilation and hospitalization, decreased mortality, and superior 1-year survival rates in mobilized PMV patients were reported. Persistent methodological limitations impair the ability to determine if these outcomes were the result of improvements in pulmonary mechanics, overall functional status, or a combination of both.
