Fructose malabsorption and fructan malabsorption are associated in patients with irritable bowel syndrome.

BACKGROUND: Food malabsorption and intolerance is implicated in gastrointestinal symptoms among patients with irritable bowel syndrome (IBS). Key triggers include fructose and fructan. Prior studies examined fructose and fructan malabsorption separately in IBS patients. None have concurrently assessed both within the same patient group. We aimed to investigate the association between fructose and fructan malabsorption in the same patients with IBS using hydrogen breath testing (HBT). METHODS: We retrospectively identified patients with IBS who underwent fructose and fructan HBTs and abstracted their results from the electronic medical record. Fructose and fructan HBTs were performed by administering a 25 g fructose solution or 10 g fructan solution, followed by breath hydrogen readings every 30 min for 3 h. Patients were positive for fructose or fructan malabsorption if breath hydrogen levels exceeded 20 ppm. RESULTS: Of 186 IBS patients, 71 (38.2%) were positive for fructose malabsorption and 91 (48.9%) were positive for fructan malabsorption. Of these patients, 42 (22.6%) were positive for fructose malabsorption and fructan malabsorption. Positive fructose HBT readings were significantly associated with positive fructan HBT readings (p = 0.0283). Patients positive for fructose malabsorption or fructan malabsorption had 1.951 times higher odds of testing positive for the other carbohydrate. CONCLUSIONS: Our results reveal a clinically significant association between fructose malabsorption and fructan malabsorption in patients with IBS. Fructan malabsorption should be assessed in patients with fructose malabsorption, and vice versa. Further studies are required to identify the mechanisms underlying our findings.

Using feedback on patient health outcomes to improve orthopaedic physical therapist practice: a quality improvement study.

OBJECTIVE: Measuring health outcomes plays an important role in patient-centred healthcare. When aggregated across patients, outcomes can provide data for quality improvement (QI). However, most physical therapists are not familiar with QI methods based on patient outcomes. This mixed-methods study aimed to develop and evaluate a QI programme in outpatient physical therapy care based on routinely collected health outcomes of patients with low-back pain and neck pain. METHODS: The QI programme was conducted by three teams of 5-6 physical therapists from outpatient settings. Plan-do-study-act cycles were used based on team-selected goals. Monthly feedback reports of process and outcomes of care, including pre-post treatment changes in Oswestry Disability Index (ODI) and Neck Disability Index (NDI), guided the QI efforts. Primary outcomes were pre-QI and post-QI changes in knowledge and attitudes towards outcome measures through a survey, and administered and self-reported compliance with using the ODI and NDI. Semistructured interviews and a focus group were conducted to evaluate the perceived value of the programme. RESULTS: Post-QI, the survey showed improvements in two items related to the role of patients and implementation of outcome measures. Registered pre-QI and post-QI completion rates were high at intake (ODI:91% pre, 88% post; NDI:75% pre, 84% post), while completion rates at discharge improved post-QI (ODI:14% pre, 66% post; NDI: 32% pre, 50% post). Perceived benefits of the QI programme included clinician and institutional accountability to processes and strategies aimed at continuous improvement in patient care. An important facilitator for programme participation was autonomy in project selection and development, while a main barrier was the time required to set up the QI project. CONCLUSION: A QI programme based on the feedback of routinely collected health outcomes of patients with low back pain and neck pain was feasible and well accepted by three pilot teams of physical therapists.

Management of non-compressible torso hemorrhage of the abdomen in civilian and military austere environments: a scoping review.

Background: Non-compressible abdominal hemorrhage (NCAH) is the leading cause of potentially preventable deaths in both civilian and military austere environments, and an improvement in mortality due to this problem has not been demonstrated during the past quarter century. Several innovations have been developed to control hemorrhage closer to the point of injury. Objective: This review assessed NCAH interventions in civilian and military settings, focusing on austere environments. It identified innovations, effectiveness, and knowledge gaps for future research. Methodology: The Joanna Briggs Institute for Evidence Synthesis methodology guided this scoping review to completion. Studies evaluating NCAH with human participants in civilian and military austere environments that were eligible for inclusion were limited to English language studies published between December 1990 and January 2023. The PCC (Participant, Concept, Context) framework was used for data synthesis. Deductive and inductive thematic analyses were used to assess the literature that met inclusion criteria, identify patterns/themes to address the research questions and identify common themes within the literature. A stakeholder consultation was conducted to review and provide expert perspectives and opinions on the results of the deductive and inductive thematic analyses. Results: The literature search identified 868 articles; 26 articles met the inclusion criteria. Textual narrative analysis of the 26 articles resulted in the literature addressing four main categories: NCAH, penetrating abdominal trauma, resuscitative endovascular balloon occlusion of the aorta (REBOA), and ResQFoam. The deductive thematic analysis aimed to answer three research questions. Research question 1 addressed the effectiveness of REBOA, damage control resuscitation, and damage control surgery in managing NCAH in austere environments. No effectiveness studies were found on this topic. Research question 2 identified three knowledge gaps in NCAH management in austere environments. The analysis identified early hemorrhage control, prehospital provider decision-making ability, and REBOA implementation as knowledge gaps in NCAH. Research question 3 identified five innovations that may affect the management of NCAH in the future: transport of patients, advanced resuscitative care, expert consultation, REBOA implementation, and self-expanding foam implementation. The inductive thematic analysis resulted in four recurrent themes from the literature: prehospital care, decision-making, hemorrhage control, and mortality in NCAH. During the stakeholders' consultation, the results of the deductive and inductive thematic analyses were reviewed and agreed on by the stakeholders. Special emphasis and discussion were given to prehospital management, expert opinions in the prehospital environment, decision-making in the prehospital environment, transport and resuscitation in the prehospital setting, REBOA, alternative discussion for research, and research gaps. Conclusion: NCAH is still a significant cause of preventable death in both military and civilian austere environments, even with ongoing research and interventions aimed at extending survival in such conditions. This scoping review has identified several potential concepts that could reduce the mortality associated with a preventable cause of death due to hemorrhage in austere environments.

Identifying facilitators and barriers to culturally responsive communication for racial, ethnic, sexual, and gender minoritized patients when screened for COVID-19 vaccinations: A scoping review protocol.

INTRODUCTION: Racial, ethnic, sexual, and gender minoritized groups are considered historically excluded groups and have been disproportionately affected by the coronavirus disease 2019 (COVID-19) pandemic. The influence of social determinants of health (SDOH), including access to screening and treatment, and other systemic and structural factors are largely responsible for these disparities. Primary care practitioner (PCP) competence in culturally responsive screening practices will be critical to reducing the impact of systemic and structural factors serving as barriers to screening and treatment. Correspondingly, improving the capacity of PCPs to communicate with patients in a culturally responsive manner may influence improved screening and treatment outcomes for minoritized groups related to COVID-19. This scoping literature review aims to determine the current breadth of literature on culturally responsive communication (CRC) in regard to COVID-19 vaccination screening for historically excluded, or minoritized groups. Results from this review will inform the development of a training series and social marketing campaign to improve PCPs capacity in CRC. This manuscript provides details on our study protocol. OBJECTIVES: This scoping literature review aims to analyze existing literature on culturally responsive COVID-19 vaccinations between PCPs and patients in the U.S., specifically for racial, ethnic, sexual, and gender minoritized groups. Results of this scoping review will inform the development of a training series and social marketing campaign to improve capacity of PCPs in this area. Additionally, the review will inform recommendations for future research. MATERIALS AND METHODS: This scoping review will be performed following the framework of Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). Relevant studies between the years 2019-2022 were identified using a rigorous search strategy across four databases: MEDLINE (via PubMed), Scopus, Cochrane (CENTRAL; via Wiley), and CINAHL (via EBSCO), using Boolean and Medical Subject Headings (MeSH) search terms. Studies will be uploaded to the data extraction tool, Covidence, to remove duplicates and perform a title/abstract screening, followed by a full-text screening. RESULTS: The data extraction and analysis phases of the scoping review are in progress. Data will be analyzed for themes related to culturally responsive COVID-19 screening practices in clinical encounters with the identified study populations. Results will be reported by theme and align to PRISMA-ScR guidelines. DISCUSSION: To our knowledge, this is the first study to use scoping methods to investigate the barriers and facilitators to CRC of COVID-19 vaccine screening for historically excluded communities in the U.S. The work and results from this research will be directly utilized for the development of nationally-accessible, continuing medical education materials to teach PCPs about CRC, as well as other materials to influence relevant policy changes within the healthcare landscape.

Teaching at the Convergence of Pandemics and Historically Excluded Patient Populations: The Challenges, and Importance, of Culturally Responsive Communication.

Issue: Historically excluded patient populations-particularly racial, ethnic, and sexually and gender minoritized people-experience gross inequities in health, worsened by the HIV and COVID-19 pandemics. Culturally responsive communication (CRC) is a vital tool health professionals can use to address these inequities. Yet, CRC can be challenging to teach, particularly during pandemics. The authors argue that pandemics magnify the powerful intersecting oppressions of heterosexism, racism, transphobia, nationalism, and sexism, essentially targeting Othered bodies for dying, a phenomenon known as necropolitics. Evidence: Five aspects of pandemics make teaching CRC more difficult and, because of the magnification of necropolitics, more critical. First, pandemics heighten teachers' and learners' personal frailties, engendering worries about their own and their families' health and increasing cognitive load. This can make it difficult for them to embrace the discomfort required of CRC, particularly when an increased patient load is squeezing instructional time. Second, guidelines for HIV and COVID-19 testing, prevention, and treatment are ever-changing, often faster than the pace of curriculum development and instructor professional development. Third, for instructors who may already be stretched thin, it is challenging to prepare learners for the variability in how their future practice contexts may address HIV and COVID-19 and, further, how to take a social justice approach to assess and resist the distinct equity issues of each of these contexts. Fourth, pandemics cause uncertain access to patient information about testing, disease status, and vaccination or pre-exposure prophylaxis. This worsens already disparate outcomes for minoritized patients and adds to the complexity of CRC curricula. Finally, virtual care is more prevalent in pandemics and teaching CRC in online contexts can be difficult. Implications: To address these challenges, we adopt the Dimensionality and R4P Health Equity Framework as a tool for evaluating academic programs for CRC so that it remains robust amidst pandemics. This tool addresses the varied social positions and identities (i.e., "dimensions") that present different opportunities for health. We offer specific evaluation questions programs can ask and approaches they can take to (a) redress past harms through removing existing racist, heteronormative and transphobic structures and repairing the damage they have done; (b) plan for a more equitable future by restructuring via policy and organizational change and providing programs that address intersectional disadvantage; and (c) critically evaluate the present by remediating current damage immediately until restructuring efforts are fully functional. As Martin Luther King, Jr. stated, "Of all the forms of inequality, injustice in healthcare is the most shocking and inhuman because it often results in physical death." It is our imperative to teach CRC with intentionality; otherwise we will support necropolitics as we continue to condone disproportionate morbidity and mortality for racialized and queer bodies.

Identifying the barriers and facilitators to culturally responsive HIV and PrEP screening for racial, ethnic, sexual, and gender minoritized patients: A scoping review protocol.

INTRODUCTION: While mainstream messaging about human immunodeficiency virus (HIV) disparities continues to highlight individual risk-taking behavior among historically marginalized groups, including racial, ethnic, sexual, and gender minoritized patients, the effect of structural factors and social determinants of health (SDOH) on morbidity and mortality remain underestimated. Systemic barriers, including a failure of adequate and acceptable screening, play a significant role in the disparate rates of disease. Primary care practitioner (PCP) competency in culturally responsive screening practices is key to reducing the impact of structural factors on HIV rates and outcomes. To address this issue, a scoping review will be performed to inform the development of a training series and social marketing campaign to improve the competency of PCPs in this area. OBJECTIVES: This scoping review aims to analyze what recent literature identify as facilitators and barriers of culturally responsive HIV and pre-exposure prophylaxis (PrEP) screening practices for historically marginalized populations, specifically racial, ethnic, sexual, and gender minoritized groups. A secondary aim is to identify themes and gaps in the literature to help guide future opportunities for research. METHODS: This scoping review will be performed following the framework set forth by Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). Relevant studies between the years 2019-2022 will be identified using a rigorous search strategy across four databases: MEDLINE (via PubMed), Scopus, Cochrane (CENTRAL; via Wiley), and CINAHL (via EBSCO), using Boolean and Medical Subject Headings (MeSH) search terms. Studies will be uploaded to the data extraction tool Covidence to remove duplicates and perform a title/abstract screening, followed by a full-text screening and data extraction. RESULTS: Data will be extracted and analyzed for themes related to culturally responsive HIV and PrEP screening practices in clinical encounters with the identified target populations. Results will be reported according to PRISMA-ScR guidelines. DISCUSSION: To our knowledge, this is the first study to use scoping methods to investigate barriers and facilitators to culturally responsive HIV and PrEP screening practices for racial, ethnic, sexual, and gender minoritized populations. The limitations of this study include the analysis restrictions of a scoping review and the timeframe of this review. We anticipate that this study's findings will interest PCPs, public health professionals, community activists, patient populations, and researchers interested in culturally responsive care. The results of this scoping review will inform a practitioner-level intervention that will support culturally sensitive quality improvement of HIV-related prevention and care for patients from minoritized groups. Additionally, the themes and gaps found during analysis will guide future avenues of research related to this topic.

Barriers and Facilitators to Implementing Simulation-Based Translational Research: A Qualitative Study.

INTRODUCTION: Translational research has been identified as a research priority for the National Institutes of Health (NIH) and the Society for Simulation in Healthcare (SSH). Despite a larger focus on translational research in recent years, the overall amount of simulation-based translational research remains low. Greater understanding of how to approach translational simulation is required to inform novice simulation and translational researchers. This study sought to answer the following research questions: How do simulation experts describe the barriers and facilitators to implementing translational simulation programs? How do simulation experts describe their various approaches to implementing translational simulation programs? What recommendations do simulation experts describe for overcoming barriers to implementing translational simulation programs? METHODS: A qualitative instrumental case study was used to elicit multiple instances of translational simulation research to gather an in-depth description from study participants. Three data sources were used: documents, semistructured interviews, and a focus group. RESULTS: Data analyses revealed 5 major themes: clarifying goals and definitions, special considerations, social networking, research, and factors external to the simulation program. CONCLUSIONS: Key findings include a lack of a standardized definitions for translational simulation and simulation-based translational research, the challenge of demonstrating the value of translational simulation, and the need for translational simulation programs to be integrated into departmental quality, patient safety, and risk management work. The findings and advice from the experts in this research can assist new researchers or those encountering challenges in implementing translational simulations.

Identifying requisite learning health system competencies: a scoping review.

OBJECTIVES: Learning health systems (LHS) integrate knowledge and practice through cycles of continuous quality improvement and learning to increase healthcare quality. LHS have been conceptualised through multiple frameworks and models. Our aim is to identify and describe the requisite individual competencies (knowledge, skills and attitudes) and system competencies (capacities, characteristics and capabilities) described in existing literature in relation to operationalising LHS. METHODS: A scoping review was conducted with descriptive and thematic analysis to identify and map competencies of LHS for individuals/patients, health system workers and systems. Articles until April 2020 were included based on a systematic literature search and selection process. Themes were developed using a consensus process until agreement was reached among team members. RESULTS: Eighty-nine articles were included with most studies conducted in the USA (68 articles). The largest number of publications represented competencies at the system level, followed by health system worker competencies. Themes identified at the individual/patient level were knowledge and skills to understand and share information with an established system and the ability to interact with the technology used to collect data. Themes at the health system worker level were skills in evidence-based practice, leadership and teamwork skills, analytical and technological skills required to use a 'digital ecosystem', data-science knowledge and skill and self-reflective capacity. Researchers embedded within LHS require a specific set of competencies. Themes identified at the system level were data, infrastructure and standardisation; integration of data and workflow; and culture and climate supporting ongoing learning. CONCLUSION: The identified individual stakeholder competencies within LHS and the system capabilities of LHS provide a solid base for the further development and evaluation of LHS. International collaboration for stimulating LHS will assist in further establishing the knowledge base for LHS.

Management of non-compressible torso hemorrhage of the abdomen in civilian and military austere/remote environments: protocol for a scoping review.

The management of non-compressible torso hemorrhage in military austere/remote environments is a leading cause of potentially preventable death in the prehospital/battlefield environment that has not shown a decrease in mortality in 26 years. Numerous conceptual innovations to manage non-compressible torso hemorrhage have been developed without proven effectiveness in this setting. This scoping review aims to assess the current literature to define non-compressible torso hemorrhage in civilian and military austere/remote environments, assess current innovations and the effectiveness of these innovations, assess the current knowledge gaps and potential future innovations in the management of non-compressible torso hemorrhage in civilian and military austere/remote environments, and assess the translational health science perspective of the current literature and its potential effect on public health. The Joanna Briggs Institute for evidence synthesis will guide this scoping review to completion. A nine-step development process, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist, will be used to enhance the methodological and reporting quality of this scoping review. The Participant, Concept, Context framework will broaden this scoping review's reach in developing a comprehensive search strategy. Thirty years will be explored to assess all relevant literature to ensure a thorough search. Two researchers will explore all the discovered literature and develop consensus on the selected literature included in this scoping review. The article will undergo review and data extraction for data analysis. The knowledge to action framework will guide the knowledge synthesis and creation of this scoping review. A narrative synthesis will systematically review and synthesize the collected literature to produce and explain a broad conclusion of the selected literature. Lastly, a consultation exercise in the form of qualitative interviews will be conducted to assess the thematic analysis results and validate the result of this scoping review. This scoping review will require Institutional Review Board approval for the expert consultation in the form of qualitative interviews. Consultants' identifying information will remain confidential. The collected and analyzed data from this scoping review will identify gaps in the literature to create an evidence-informed protocol for the management of non-compressible torso hemorrhage of the abdomen in civilian and military austere/remote environments. The results of this scoping review will be distributed in peer-reviewed journals and educational, medical presentations. Scoping Review Protocol, Level IV.

C4Tech: Virtual connections between the classrooms, clinicians, and community clinics to bridge the gap between research and practice.

AIM: E-learning technologies are becoming vital components of medical and health professions education, as highlighted during the current coronavirus disease (COVID-19) pandemic. The National Academy of Medicine (NAM) considers education technologies essential to forming connections between education and healthcare delivery systems, which promote evidence-based practice and continuous learning and quality improvement in healthcare. There is a lack of evidence-based models to guide the integration of technology in medical and health profession education, in particular models that form synergistic linkages between healthcare education and delivery systems. This paper presents the evaluation of an innovative blended learning model, which leverages virtual technology to connect students in the classroom with clinicians in community clinics (C4Tech) for authentic learning related to quality improvement (QI) and social determinants of health (SDH). METHOD: This study applied a case study approach to evaluate the efficacy of the C4Tech model in supporting learning outcomes and assessed how virtual collaboration influenced the process of learning. RESULTS: This study contributes to a more comprehensive understanding of how to design effective blended courses that connect the healthcare education and delivery systems through virtual technology. It also demonstrates how to connect students and practicing clinicians virtually to design evidence-based quality improvement projects.

Learning health systems from an academic perspective: establishing a collaboratory within a school of medicine and health sciences.

Learning Health Systems (LHSs) seek continuous improvement through the translation and integration of internally and externally generated knowledge across stakeholders within and external to the organization, yet current approaches are primarily described from the healthcare delivery perspective, leaving teaching and research responsibilities underexposed. Academic medical centers offer a unique perspective on LHSs because their mission includes teaching, research, and healthcare. This introduces an opportunity to enact, educate, and study processes and outcomes of LHSs within a single system. Little information is available to describe these processes and outcomes, resulting in a knowledge gap regarding the role of education and research in the quality improvement cycles and learning of LHSs. To close this knowledge gap, The George Washington University School of Medicine and Health Sciences initiated the Health Research and Education Collaboratory (GW Collaboratory) in 2017. The GW Collaboratory was established to study mechanisms supporting continuous quality improvement and learning in health systems within an academic medical center. We envision the GW Collaboratory as interconnected knowledge nodes facilitating collaboration among clinicians, patients, researchers, and educators to study the knowledge generation, dissemination, application, and evaluation required for continuous quality improvement and learning. We employ a project-based approach to foster communities of learning focused on exploring specific health problems of interest. We propose the GW Collaboratory as one model by which academic medical centers can contribute to the science of LHS.

Connecting Classrooms, Clinicians, and Community Clinics Through Technology (C4Tech) for Active and Collaborative Learning.

PURPOSE: This pilot study investigated the level of cognition that physician assistant (PA) students achieved through adoption of an innovative blended learning model that connects the classroom, clinicians, and community clinics through electronic-learning (e-learning) technologies (C4Tech) used in a PA course. This education intervention aimed to facilitate authentic learning collaborations between PA students and practicing clinicians that would result in higher-order cognition related to the manifestations of social determinants of health and health disparities. METHODS: A case study approach was adopted to assess levels of cognition and changes in those levels resulting from application of an innovative blended learning model. Content analysis using Bloom's taxonomy of cognitive domains facilitated determination levels of cognition and changes in those levels. The sample of 8 groups comprised 70 PA students and 8 clinical instructors from community clinics with underrepresented patient populations. RESULTS: Analysis of 2 course assignments revealed that application of the C4Tech model yields high levels of cognition. By the course's end, all 8 groups achieved at least the "evaluate" level of cognition and half of the groups achieved the highest level of cognition, the "create" level. A wide variation in the level of cognition was demonstrated between the first and second assignments in each group and among groups. CONCLUSION: Our findings suggest that e-learning technologies can be effective in blending classrooms and work environments for authentic and collaborative learning. Adoption of the C4Tech model yielded higher-order cognition related to course content.

Hot weather increases competition between dairy cows at the drinker.

Heat-stressed dairy cows on pasture will compete for resources that aid cooling, but it is not known how heat stress affects the competition for water by indoor-housed cows. The aim of this observational study was to evaluate how heat stress affects the behavior of indoor-housed cows at the drinker at both group and cow levels. For 3 wk after calving, cows were housed in a dynamic group of 20 animals in a pen with 12 electronic feed bins, 2 electronic water bins, and 24 freestalls. A total of 69 lactating Holstein dairy cows were enrolled over the 59-d study. The electronic water bins recorded time spent at the drinker, frequency of visits, water intake, and competitive events for 24 h/d. Competitive events were quantified using the number of replacements (recorded when there was a ≤29-s interval between 2 cows sequentially visiting the same drinker). The number of replacements a cow was involved in was used to determine her level of competitive success at the drinker (low, medium, high). The temperature-humidity index (THI) was recorded by the local weather station, and moving averages for daily maximum THI over a 3-d period were calculated. For the analysis of time spent at the drinker, frequency of visits, and water intake, the measures from all cows were averaged to create 1 observation per day, and the number of replacements at the drinker was summed. A linear regression was performed to determine the relationship between THI and group-level drinking behavior. At the cow level, a repeated measures mixed model, with fixed effects of level of competitive success, milk yield, and 3-d maximum THI and a first-order autoregressive covariance structure, was used to determine how increasing THI affects the drinking behavior of individual cows based on their level of competitive success. Feed intake was included as a fixed effect in the water intake model. We found that, with increasing THI, cows drank more water, spent more time at the drinker, made more visits to the drinker, and engaged in more competitive events at the drinker. In exploratory analysis, we found that cows with low competitive success at the drinker shifted their drinking behavior to avoid the drinker at the hottest and most competitive time of day. These results indicate that behavior can be used to indicate when cows feel hot. These measures may be of practical value in deciding when to provide cooling, especially for farms where attendance at the drinker can be monitored electronically.

Technical note: Using an electronic drinker to monitor competition in dairy cows.

The objective of this study was to determine whether data from an electronic drinking system that tracks individual animal attendance with ear tag transponders could be used to detect social competition between dairy cows at the drinker. Specifically, we sought to identify the interval between one cow leaving the drinker and another cow taking her place that most accurately identified competitive replacements (when physical contact initiated by one cow causes the other to entirely remove her head from the drinker and the initiator subsequently places her head in the same drinker). The optimal interval to accurately identify replacements at the drinker was determined using a receiver operating characteristic curve and by evaluating the sensitivity (Se), specificity (Sp), and confusion matrix values (true positives, true negatives, false positives, false negatives) of different thresholds identified by 3 metrics: the Youden index, the point closest to (0,1) on the curve, and the point where Se roughly equals Sp. Lactating Holstein dairy cows (n = 20) were monitored for 4 consecutive 24-h periods by video recording and with an electronic drinking system. Two periods were used to identify the optimal interval (the baseline set), and the other 2 periods were used to validate the interval (the validation set). The occurrence of a replacement identified by video was paired with the interval between drinking events of 2 cows at the same electronic drinker to identify the interval that best predicted replacement events. Based on the low prevalence of replacement events compared with nonreplacement events, the interval with the lowest number of false positives was considered optimal. Of the 3 potential metrics, the point on the receiver operating characteristic curve where Se and Sp were roughly equal yielded the fewest false positives. The optimal interval to identify replacements at the drinker was ≤29 s, with 82% Se and 83% Sp in the baseline set. This interval was found to have 85% Se and 89% Sp when applied to the validation set. These results indicate that social competition between dairy cows at the drinker can be accurately measured with an electronic drinking system.

Comparing student outcomes in traditional vs intensive, online graduate programs in health professional education.

BACKGROUND: Health professions' education programs are undergoing enormous changes, including increasing use of online and intensive, or time reduced, courses. Although evidence is mounting for online and intensive course formats as separate designs, literature investigating online and intensive formats in health professional education is lacking. The purpose of the study was to compare student outcomes (final grades and course evaluation ratings) for equivalent courses in semester long (15-week) versus intensive (7-week) online formats in graduate health sciences courses. METHODS: This retrospective, observational study compared satisfaction and performance scores of students enrolled in three graduate health sciences programs in a large, urban US university. Descriptive statistics, chi square analysis, and independent t-tests were used to describe student samples and determine differences in student satisfaction and performance. RESULTS: The results demonstrated no significant differences for four applicable items on the final student course evaluations (p values range from 0.127 to 1.00) between semester long and intensive course formats. Similarly, student performance scores for final assignment and final grades showed no significant differences (p = 0.35 and 0.690 respectively) between semester long and intensive course formats. CONCLUSION: Findings from this study suggest that 7-week and 15-week online courses can be equally effective with regard to student satisfaction and performance outcomes. While further study is recommended, academic programs should consider intensive online course formats as an alternative to semester long online course formats.
