Using poster presentation to assess large classes: a case study of a first-year undergraduate module at a South African university
Authors: Ross Andrew , Dlungwane Thembelihle , Van Wyk Jacqueline 
Published: November 2019

AbstractBackgroundThe massification of higher education is often associated with poor student engagement, poor development of their critical thinking, inadequate feedback and poor student throughput. These factors necessitate the need to devise novel, innovative methods to teach, assess and provide feedback to learners to counter the restrictions imposed due to the large class learning environments. This study was conducted to ascertain the perceptions of 1st year medical students and staff at the Nelson Mandela School of Medicine regarding the value of poster presentations as a strategy to enhance learning, assessment and feedback.MethodsThis was an exploratory observational, descriptive cross-sectional, case study. Data was collected through separate student and staff questionnaires that required participant responses on a five-point Likert scale. The data was extracted into Excel spreadsheets for quantitative analysis.ResultsTwo-hundred- and-thirty (92%) student questionnaires were returned (N = 250). Most students indicated that the design and presentation of the poster had helped them to select important material (92%), understand and describe disadvantage (86%) and to make a difference in the community (92%). The students agreed that the poster assessment was an efficient (81%) and fair method (75%) that provided opportunities for meaningful feedback. Ten staff members responded to the questionnaire. Most staff members (90%) indicated that the poster presentation had allowed students to demonstrate their engagement in a meaningful and appropriate way around issues of disadvantage and HIV and agreed that the poster presentations allowed for immediate and effective feedback.ConclusionStudents’ interactions in the tasks promoted active engagement with others and course material; the development of higher order thinking and skills which added to students’ accounts of transformative learning experiences. They could describe and illustrate the difference that they had made in their chosen community. The poster presentations allowed for quick and efficient marking, immediate feedback and an opportunity to validate the students’ participation.Poster presentations offered an innovative way to encourage deep meaningful engagement and learning amongst peers and facilitators. Poster presentations should be more widely considered as an innovative way of encouraging deeper engagement and learning in a large class setting.

Abstract
Background
Citizen science is increasingly prevalent in the biomedical sciences, including the field of human genomics. Genomic citizen science initiatives present new opportunities to engage individuals in scientific discovery, but they also are provoking new questions regarding who owns the outputs of the research, including intangible ideas and discoveries and tangible writings, tools, technologies, and products. The legal and ethical claims of participants to research outputs become stronger—and also more likely to conflict with those of institution-based researchers and other stakeholders—as participants become more involved, quantitatively and qualitatively, in the research process. It is not yet known, however, how genomic citizen science initiatives are managing the interests of their participants in accessing and controlling research outputs in practice. To help fill this gap, we conducted an in-depth review of relevant policies and practices of U.S.-based genomic citizen science initiatives.

Methods
We queried the peer-reviewed literature and grey literature to identify 22 genomic citizen science initiatives that satisfied six inclusion criteria. A data collection form was used to capture initiative features, policies, and practices relevant to participants’ access to and control over research outputs.

Results
This analysis revealed that the genomic citizen science landscape is diverse and includes many initiatives that do not have institutional affiliations. Two trends that are in apparent tension were identified: commercialization and operationalization of a philosophy of openness. While most initiatives supported participants’ access to research outputs, including datasets and published findings, none supported participants’ control over results via intellectual property, licensing, or commercialization rights. However, several initiatives disclaimed their own rights to profit from outputs.

Conclusions
There are opportunities for citizen science initiatives to incorporate more features that support participants’ access to and control over research outputs, consistent with their specific objectives, operations, and technical capabilities.

Abstract
Background
Neuropsychological tests (NPTs) are important tools for informing diagnoses of cognitive impairment (CI). However, interpreting NPTs requires specialists and is thus time-consuming. To streamline the application of NPTs in clinical settings, we developed and evaluated the accuracy of a machine learning algorithm using multi-center NPT data.

Methods
Multi-center data were obtained from 14,926 formal neuropsychological assessments (Seoul Neuropsychological Screening Battery), which were classified into normal cognition (NC), mild cognitive impairment (MCI) and Alzheimer’s disease dementia (ADD). We trained a machine learning model with artificial neural network algorithm using TensorFlow (https://www.tensorflow.org) to distinguish cognitive state with the 46-variable data and measured prediction accuracies from 10 randomly selected datasets. The features of the NPT were listed in order of their contribution to the outcome using Recursive Feature Elimination.

Results
The ten times mean accuracies of identifying CI (MCI and ADD) achieved by 96.66 ± 0.52% of the balanced dataset and 97.23 ± 0.32% of the clinic-based dataset, and the accuracies for predicting cognitive states (NC, MCI or ADD) were 95.49 ± 0.53 and 96.34 ± 1.03%. The sensitivity to the detection CI and MCI in the balanced dataset were 96.0 and 96.0%, and the specificity were 96.8 and 97.4%, respectively. The ‘time orientation’ and ‘3-word recall’ score of MMSE were highly ranked features in predicting CI and cognitive state. The twelve features reduced from 46 variable of NPTs with age and education had contributed to more than 90% accuracy in predicting cognitive impairment.

Conclusions
The machine learning algorithm for NPTs has suggested potential use as a reference in differentiating cognitive impairment in the clinical setting.
Secondary care usage and characteristics of hospital inpatients referred to a UK homeless health team: a retrospective service evaluation
Authors: Field Hannah , Hudson Briony , Hewett Nigel , Khan Zana 
Published: November 2019

Abstract
Background
UK “Pathway” teams offer specialist hospital care coordination for people experiencing homelessness. Emergency healthcare use is high among homeless people, yet “homelessness” is not routinely coded in National Health Service (NHS) data. Pathway team records provide an opportunity to assess patterns in admissions and outcomes for inpatients identified as homeless.

Methods
Retrospective analysis of patients referred to “Pathway” homelessness teams in seven UK hospitals to explore the patterns of hospital admission, morbidity, secondary healthcare utilisation and housing status. Each patient was individually identified as experiencing homelessness. Within a six-month period, demographic data, reason for admission, morbidity, mortality and secondary care hospital usage 120-days before and 120-days after the index admission was collected.

Results
A total of 1009 patients were referred, resulting in 1135 admissions. Most admissions had an acute physical health need (94.9%). Co-morbid mental illness and/or substance misuse was common (55.7%). Reasons for admission included mental and behavioral disorders (overdose, alcohol withdrawal or depression, 28.3%), external causes of morbidity and mortality (assault or trauma, 18.7%), and injury, poisoning and external causes (head injury, falls and fractures, 12.4%). Unplanned Emergency Department attendances reduced after index admission and unplanned hospital admissions increased slightly. Planned admissions doubled and total bed days increased. Housing status was maintained or improved for over 60% of inpatients upon discharge. Within 12 months of index admission, 50 patients (5%) died, 15 deaths (30%) occurred during the index admission.

Conclusions
Disengagement with health services is common among homeless people. Many deaths are due to treatable medical conditions (heart disease, pneumonia, cancer). Observed increases in planned admissions suggests intervention from Pathway teams facilitates necessary investigations and treatment for homeless people. Equity, parity of care, and value should be inbuilt interventions for inclusion health groups and evaluations need to move beyond simply seeking cost reductions.
A realist evaluation of the implementation of open visiting in an acute care setting for older people
Authors: Hurst Helen , Griffiths Jane , Hunt Carrie , Martinez Ellen 
Published: November 2019

Abstract
Background
Open visiting refers to the principle of unrestricted visiting hours in the hospital setting to enable relatives, families and carers to visit at any time. There has been recognition that open visiting supports the principle of patient and family supported care and improves communication. Despite this there has been difficulty in implementing open visiting and barriers identified. The aims of this study were therefore to evaluate the implementation of open visiting, the barriers to implementation, sustainability and the impact of open visiting on communication between health care professionals, families and carers.

Methods
The study was conducted on two large acute wards for the older person. Realist evaluation methods were used to understand ‘what works well, how, for whom and to what extent.’ Mixed methods were employed including qualitative interviews and descriptive analyses of routine data sets. Following the methodology of realist evaluation, programme theories were identified a long with the context, mechanisms and outcomes of implementation, to better understand the implementation process.

Results
The results of this study identified some key findings, demonstrating that open visiting does improve communication and can help to build trusting relationships between families/carers and health care professionals (HCP). Barriers to implementation were based on the belief that it would impinge on routines within the ward setting. To achieve the principles of patient and family/carer centred care, the key mechanisms are the confidence and skills of individual nurses and health care assistants to engage with relatives/carers, whilst retaining a sense of control, particularly when care is being delivered to other patients.

Conclusion
In summary, open visiting creates a positive culture which fosters better relationships between families/carers and HCPs. Involving families/carers as partners in care does not happen automatically in an environment where open visiting is the policy, but requires engagement with staff to encourage and support relatives/carers.
The Value Equation: Three complementary propositions for reconciling fidelity and adaptation in evidence-based practice implementation
Authors: von Thiele Schwarz Ulrica , Aarons Gregory A. , Hasson Henna 
Published: November 2019

AbstractBackgroundThere has long been debate about the balance between fidelity to evidence-based interventions (EBIs) and the need for adaptation for specific contexts or particular patients. The debate is relevant to virtually all clinical areas. This paper synthesises arguments from both fidelity and adaptation perspectives to provide a comprehensive understanding of the challenges involved, and proposes a theoretical and practical approach for how fidelity and adaptation can optimally be managed.DiscussionThere are convincing arguments in support of both fidelity and adaptations, representing the perspectives of intervention developers and internal validity on the one hand and users and external validity on the other. Instead of characterizing fidelity and adaptation as mutually exclusive, we propose that they may better be conceptualized as complimentary, representing two synergistic perspectives that can increase the relevance of research, and provide a practical way to approach the goal of optimizing patient outcomes. The theoretical approach proposed, the “Value Equation,” provides a method for reconciling the fidelity and adaptation debate by putting it in relation to the value (V) that is produced. The equation involves three terms: intervention (IN), context (C), and implementation strategies (IS). Fidelity and adaptation determine how these terms are balanced and, in turn, the end product – the value it produces for patients, providers, organizations, and systems. The Value Equation summarizes three central propositions: 1) The end product of implementation efforts should emphasize overall value rather than only the intervention effects, 2) implementation strategies can be construed as a method to create fit between EBIs and context, and 3) transparency is vital; not only for the intervention but for all of the four terms of the equation.SummaryThere are merits to arguments for both fidelity and adaptation. We propose a theoretical approach, a Value Equation, to reconciling the fidelity and adaptation debate. Although there are complexities in the equation and the propositions, we suggest that the Value Equation be used in developing and testing hypotheses that can help implementation science move toward a more granular understanding of the roles of fidelity and adaptation in the implementation process, and ultimately sustainability of practices that provide value to stakeholders.

Abstract
Background
Preterm birth is a worldwide challenge with the highest burden in low- and middle-income countries. Despite availability of low-cost interventions to decrease mortality of preterm, low birth weight, and sick newborns, these interventions are not well integrated in the health systems of low- and middle-income countries. The aim of this study was to assess, from the perspective of key stakeholders comprising leaders in the public health system, the health system readiness to support health care facilities in the care provided to preterm, low birth weight, and sick newborns in different regions of Ethiopia.

Methods
A qualitative assessment using in-depth interviews with health facility leaders was conducted in health facilities in 3 regions of Ethiopia from December 2017 to February 2018. The interview guide was developed using a modified version of the World Health Organization health system building blocks.

Results
Across the public health system, adequate and reliable space, power, and water were problematic. Human resource issues (training, staffing, and retention) were critical to being able to properly care for preterm, low birth weight, and sick newborns. Problems with functional equipment and equipment distribution systems were widespread. Funds were lacking to support preterm, low birth weight, and sick newborn needs in facilities. Data collection practices, data quality, and data utilization were all problematic. There were gaps in the availability of guidelines and protocols, specifically targeting preterm, low birth weight, and sick newborn care. Key facilitators, information disseminators, and influencers identified in the study were the Health Development Army, community and religious leaders, and mothers and families who had had positive experiences or outcomes of care.

Conclusions
The Ethiopian health system has opportunities across all 7 World Health Organization health system building blocks to strengthen readiness to support health facilities to provide quality care and improve outcomes for preterm, low birth weight, and sick newborns.
The impact of nurse staffing levels and nurse’s education on patient mortality in medical and surgical wards: an observational multicentre study
Authors: Haegdorens Filip , Van Bogaert Peter , De Meester Koen , Monsieurs Koenraad G. 
Published: November 2019

Abstract
Background
Growing evidence indicates that improved nurse staffing in acute hospitals is associated with lower hospital mortality. Current research is limited to studies using hospital level data or without proper adjustment for confounders which makes the translation to practice difficult.

Method
In this observational study we analysed retrospectively the control group of a stepped wedge randomised controlled trial concerning 14 medical and 14 surgical wards in seven Belgian hospitals. All patients admitted to these wards during the control period were included in this study. Pregnant patients or children below 17 years of age were excluded. In all patients, we collected age, crude ward mortality, unexpected death, cardiac arrest with Cardiopulmonary Resuscitation (CPR), and unplanned admission to the Intensive Care Unit (ICU). A composite mortality measure was constructed including unexpected death and death up to 72 h after cardiac arrest with CPR or unplanned ICU admission. Every 4 months we obtained, from 30 consecutive patient admissions across all wards, the Charlson comorbidity index. The amount of nursing hours per patient days (NHPPD) were calculated every day for 15 days, once every 4 months. Data were aggregated to the ward level resulting in 68 estimates across wards and time. Linear mixed models were used since they are most appropriate in case of clustered and repeated measures data.

Results
The unexpected death rate was 1.80 per 1000 patients. Up to 0.76 per 1000 patients died after CPR and 0.62 per 1000 patients died after unplanned admission to the ICU. The mean composite mortality was 3.18 per 1000 patients. The mean NHPPD and proportion of nurse Bachelor hours were respectively 2.48 and 0.59. We found a negative association between the nursing hours per patient day and the composite mortality rate adjusted for possible confounders (B = − 2.771, p = 0.002). The proportion of nurse Bachelor hours was negatively correlated with the composite mortality rate in the same analysis (B = − 8.845, p = 0.023). Using the regression equation, we calculated theoretically optimal NHPPDs.

Conclusions
This study confirms the association between higher nurse staffing levels and lower patient mortality controlled for relevant confounders.

Abstract
Background
The aim of the study was to identify the proportion of female sex workers, men who have sex with men, and people who inject drugs who had accessed HIV prevention services at public health facilities and peer-led facilities, their level of satisfaction with these services, and perceived barriers and challenges to accessing HIV services from public and peer-led HIV prevention service providers.

Methods
A mixed-method approach was used to collect data from key populations in the four states in Nigeria. Quantitative data collected included level of satisfaction with and barriers to use of public and peer-led facilities. In-depth interviews and focus-group discussions were conducted to explore reasons for satisfaction with and barriers to use of services. Descriptive and bivariate analyses were was conducted for quantitative data. Qualitative data were summaried, emerging themes identified, described and quotes reflecting the themes corresponding to interview questions highlighted.

Results
Nine hundred sixty-seven persons responded to questions on the use of public health or/and peer-led facilities. Two hundred thirty-eight (49.4%) respondents had received HIV and sexual and reproductive health services through public health facilities, and 236 (48.7%) had received the services through peer-led facilities. Significantly more respondents were satisfied with the quality of services provided by peer-led organisations than with public health facilities with respect to service providers listening to respondent’s problems and concerns (p = 0.007),privacy and confidentiality (p = 0.04) and respect of rights of service recipients (p = 0.04). Significantly more respondents using peer-led organisations than those using public health facilities identified no barriers to service access (p = 0.003). More respondents using public health facilities than peer-led facilities identified cost of services (p = 0.01), confidentiality (p = 0.002), waiting time (p < 0.01) and staff attitude (p = 0.001) as barriers to service access. Thee was no difference in the proportion of respondents willing to discontinue their use of either facilities (p = 0.08). Qualitative data revealed that concerns with access of services at the public health facility were due mainly to stigma and the effects of the same-sex prohibition law.

Conclusion
Key populations were more satisfied receiving HIV prevention services at peer-led organisations than at public health facilities.
