COVID-19 in the homeless population: a scoping review and meta-analysis examining differences in prevalence, presentation, vaccine hesitancy and government response in the first year of the pandemic.

AIMS: People experiencing homelessness (PEH) have been identified as being increasingly susceptible to Coronavirus disease (COVID-19), with policies enacted to test, isolate, increase hygiene practices and prioritise vaccines among this population. Here, we conduct a scoping review of the current evidence-base pertaining to the prevalence and presentation of COVID-19 in PEH, COVID-vaccine hesitancy rates and government interventions enacted within the first year of the pandemic for PEH. MATERIALS AND METHODS: A systematic search was conducted on Pubmed, Cochrane, Embase and MedRxiv databases for studies reporting primary data on COVID-19 prevalence and clinical characteristics in PEH, vaccine uptake for PEH and policies enacted targeting PEH. Study qualities were assessed with The National Heart, Lung and Blood Institute's set of Study Quality. RESULTS: Eighty-three studies were included in our final analysis. The overall prevalence of symptomatic COVID-19 infection in PEH is estimated at 35%. The most common symptoms found were cough and shortness of breath, followed by fever. Concerns regarding vaccine hesitancy amongst PEH related to thoroughness of COVID-19 vaccine clinical trials, side effects and mistrust of the government. The main strategies implemented by governments were mass testing, adaption of healthcare service provision, provision of alternative housing, encouraging personal hygiene (hand sanitation and mask wearing), and inter-organisational communication. DISCUSSION: In our meta-analysis, 35% of PEH with a COVID-19 infection presented symptomatically; the low prevalence of symptomatic COVID-19 infection suggests widespread testing following outbreaks would be beneficial for this group of individuals. Temporary recuperation units and measures for housing stability in the pandemic, namely provision of alternative housing and stopping evictions, were found to be highly effective. High rates of vaccine hesitancy means that education and encouragement towards vaccination would be beneficial for this vulnerable population, where comorbidities are common. Finally increased focus in research should be placed on the mental health burden of COVID-19 and the pandemic on PEH moving forwards.

Effect of integrated intervention to prevent child drowning in rural areas of Guangdong, China: a cluster randomized controlled trial.

BACKGROUND: Drowning is the leading cause of death for children under the age of 15 years in Guangdong Province, China. This serious public health issue also exists in low- and middle-income countries (LMICs), which have few value-integrated intervention programs. The current study presents an integrated intervention project that aims to explore an effective pattern of prevention for child drowning in rural areas and feasibility to perform in other LMICs. METHODS: We conducted a cluster randomized controlled trial by comparing the incidence of non-fatal drowning among children in two groups in rural areas of southern China. We recruited the participants in two phases and reached a total of 10 687 students from 23 schools at two towns in Guangdong Province, China. At the first and second phases, 8966 and 1721 students were recruited, respectively. RESULTS: The final evaluation questionnaires were collected after 18 months of integrated intervention, where we obtained 9791 data from Grades 3-9. The incidence of non-fatal drowning between the intervention and control groups after intervention did not differ significantly from the baseline according to the total number of students, male students, female students and Grades 6-9 [0.81; 95% confidence interval (CI): [0.66, 1.00]; p = 0.05, 1.17; 95% CI: [0.90, 1.51]; p = 0.25, 1.40; 95% CI: [0.97, 2.02]; p = 0.07 and 0.97; 95% CI: [0.70, 1.34]; p = 0.86], except for Grades 3-5 (1.36; 95% CI: [1.02, 1.82]; p = 0.037). The study observed a significantly positive benefit of awareness and risk behaviours of non-fatal drowning between the intervention and control groups (0.27, 95% CI: [0.21, 0.33]; p = 0.00, -0.16; 95% CI: [-0.24, -0.08]; p = 0.00). CONCLUSIONS: The integrated intervention exerted a significant impact on the prevention and management of child non-fatal drowning, especially in rural areas.

Selecting Review Outcomes for Systematic Reviews of Public Health Interventions.

For systematic reviews to have an impact on public health, they must report outcomes that are important for decision-making. Systematic reviews of public health interventions, however, have a range of potential end users, and identifying and prioritizing the most important and relevant outcomes represents a considerable challenge.In this commentary, we describe potentially useful approaches that systematic review teams can use to identify review outcomes to best inform public health decision-making. Specifically, we discuss the importance of stakeholder engagement, the use of logic models, consideration of core outcome sets, reviews of the literature on end users' needs and preferences, and the use of decision-making frameworks in the selection and prioritization of outcomes included in reviews.The selection of review outcomes is a critical step in the production of public health reviews that are relevant to those who use them. Utilizing the suggested strategies may help the review teams better achieve this.

'Evidence' within local authority decision making.

Michael Cook looks at the role of an embedded Public Health Information Specialist highlighting the ways the core evidence, information and knowledge skills are used to progress Public Health activity in local government settings. Acknowledging the current pandemic, he explores how COVID-19 has dominated all aspects of health and social care, and outlines how evidence services have work within these complex Public Health systems to lead the local response and recovery efforts.

Addressing Health Equity in Public Health Practice: Frameworks, Promising Strategies, and Measurement Considerations.

This review describes the context of health equity and options for integrating equity into public health practice. We first discuss how the conceptualization of health equity and how equity considerations in US public health practice have been shaped by multidisciplinary engagements. We then discuss specific ways to address equity in core public health functions, provide examples of relevant frameworks and promising strategies, and discuss conceptual and measurement issues relevant to assessing progress in moving toward health equity. Challenges and opportunities and their implications for future directions are identified.

Patterns of pesticide usage in agriculture in rural Tanzania call for integrating agricultural and public health practices in managing insecticide-resistance in malaria vectors.

BACKGROUND: Unrestricted use of pesticides in agriculture is likely to increase insecticide resistance in mosquito vectors. Unfortunately, strategies for managing insecticide resistance in agriculture and public health sectors lack integration. This study explored the types and usage of agricultural pesticides, and awareness and management practices among retailers and farmers in Ulanga and Kilombero districts in south-eastern Tanzania, where Anopheles mosquitoes are resistant to pyrethroids. METHODS: An exploratory sequential mixed-methods approach was employed. First, a survey to characterize pesticide stocks was conducted in agricultural and veterinary (agrovet) retail stores. Interviews to assess general knowledge and practices regarding agricultural pesticides were performed with 17 retailers and 30 farmers, followed by a survey involving 427 farmers. Concurrently, field observations were done to validate the results. RESULTS: Lambda-cyhalothrin, cypermethrin (both pyrethroids) and imidacloprids (neonicotinoids) were the most common agricultural insecticides sold to farmers. The herbicide glyphosate (amino-phosphonates) (59.0%), and the fungicides dithiocarbamate and acylalanine (54.5%), and organochlorine (27.3%) were also readily available in the agrovet shops and widely used by farmers. Although both retailers and farmers had at least primary-level education and recognized pesticides by their trade names, they lacked knowledge on pest control or proper usage of these pesticides. Most of the farmers (54.4%, n = 316) relied on instructions from pesticides dealers. Overall, 93.7% (400) farmers practised pesticides mixing in their farms, often in close proximity to water sources. One-third of the farmers disposed of their pesticide leftovers (30.0%, n = 128) and most farmers discarded empty pesticide containers into rivers or nearby bushes (55.7%, n = 238). CONCLUSION: Similarities of active ingredients used in agriculture and malaria vector control, poor pesticide management practices and low-levels of awareness among farmers and pesticides retailers might enhance the selection of insecticide resistance in malaria vectors. This study emphasizes the need for improving awareness among retailers and farmers on proper usage and management of pesticides. The study also highlights the need for an integrated approach, including coordinated education on pesticide use, to improve the overall management of insecticide resistance in both agricultural and public health sectors.

State Health Official Career Advancement and Sustainability Evaluation-Description of the Methods Used in the SHO-CASE Study.

State health officials (SHOs) lead state governmental public health agencies, playing an important role in their states. However, little comprehensive research has examined SHOs or characteristics of these leaders, limiting evidence about ways to improve SHO selection and subsequent performance. This brief describes the methods of the SHO-CASE study focused on current and former SHOs in state public health agencies. Methods used include qualitative components that informed the development of survey questions, survey administration, and survey response. A total of 147 SHOs responded to the SHO survey representing every state and Washington, District of Columbia. The SHO-CASE study survey database represents the most comprehensive database of its kind regarding a range of attributes of current and former SHOs. These data can be used to explore factors contributing to SHO success including valuable insights into effectively working with the states' elected officials.

Early hospital readmission after kidney transplantation under a public health care system.

Early hospital readmission (EHR) is associated with increased mortality after kidney transplantation. This is influenced by population demographics and the comprehensiveness of the healthcare system. We investigated the incidence and risk factors associated with EHR and 1-year patient and graft survivals. METHODS: We included all recipients of kidney transplant between 2011 and 2012. We excluded recipients younger than 18 years, retransplants and who died or lost the graft during the index hospital admission. RESULTS: Among 1175 recipients, the incidence of EHR was 26.6%. The main reasons for EHR were infection (67%), surgical complications (14%), and metabolic disturbances (11%). Independent risk factors associated with EHR were recipient age (OR = 1.95, 95% CI 1.46-2.63, P < 0.001), CMV serology negative (OR = 2.2, 95% CI 1.31-3.65, P = 0.003), use of rabbit anti-thymocyte globulin (OR = 2.06, 95% CI 1.33-3.13, P < 0.001), treatment for acute rejection during index hospitalization (OR = 1.68, 95% CI 1.15-2.47, P = 0.008), and length of stay (OR = 1.72, 95% CI 1.18-2.5, P = 0.005). Patient (88.8% vs 97.6%, P < 0.001) and death-censored graft (97.4% vs 99.0%, P < 0.001) survivals were inferior comparing patients with and without EHR. Conclusion EHR was independently associated with mortality (OR 4.01, 95% CI 2.13-7.54, P < 0.001), but its incidence and causes are directly related to the local characteristics of the population and healthcare system.

Prevalence of psychological distress and associated factors among adult tuberculosis patients attending public health institutions in Dire Dawa and Harar cities, Eastern Ethiopia.

BACKGROUND: In developing countries, the prevalence of psychological distress was higher among tuberculosis patients. Patients with tuberculosis infection were more prone to psychological distress than peoples without tuberculosis. However, little studies were conducted on psychological distress among tuberculosis patients in Ethiopia, particularly in the Eastern Ethiopian health institutions. METHODS: Institution-based cross-sectional study design was conducted. Based on the TB burden, four hospitals and six health centers were selected from Dire Dawa and Harar cities. Socio-demographic factors, psychological distress, TB related stigma experience, and alcohol use data were collected by face to face interview while TB and HIV related variables collected from TB registration book. All TB patients from the first month of TB treatment initiation through 6 were consecutively interviewed by trained data collectors from January to February 2018. The collected data were entered into Epi Data Version 3.1 software and exported into SPSS window version 20 for analysis. Bivariate and multivariate binary logistic regression was carried out. All variables with P-value ≤0.25 were taken into the multivariate model. Crude and adjusted odds ratios with a 95% confidence interval were estimated, and variables with P-value less than 0.05 in the final model were taken as significant predictors of psychological distress. RESULTS: The prevalence of psychological distress among tuberculosis in this study population was 63.3% (95% CI: 58.1, 68.1). Being from rural residence (AOR: 1. 98; 95% CI: 1.01,3.86), co-infection TB- HIV (AOR: 2.15; 95% CI:1.02, 4.56), presence of at least one chronic disease (AOR:3.04; 95% CI:1.59,5.79), experience of stigma (AOR: 1.71; 95% CI:1.01, 2.90), Pulmonary and MDR-TB (AOR:2.53; 95% CI:1.50,4.28) and smoking cigarette (AOR:2.53; 95% CI:1.06,6.03) were associated with psychological distress. CONCLUSIONS: In this study, almost two-thirds of the tuberculosis patients had psychological distress. Chronic disease morbidity, HIV-TB co-infection and experienced TB related stigma were associated with psychological distress. Attention should be given to chronic diseases including HIV/AIDS diagnosis and referring to chronic disease units to prevent the impact on mental health. Consideration should be given for psychological distress and linking moderate to severe form of the disease to the Psychiatric clinics to hinder its effects.

Public health nurses' activities at a time of specialization in nursing-A national study.

OBJECTIVES: To provide a detailed, up-to-date account of the job description and practice areas of current public health nurses. DESIGN AND SAMPLE: A cross-sectional study. A sample of 824 public health nurses, 80% of public health nurses in Israel, participated in a national structured survey. MEASURES: A structured questionnaire eliciting self-reported public health nursing activities, priorities, perceived deficiencies, and job satisfaction was compiled. RESULTS: Nearly 70% of surveyed public health nurses provided individual-level interventions and less population-health-focused activities such as community needs assessments and development and implementation of community-based projects. CONCLUSIONS: Advanced training should be required in several areas of practice and the scope of public health nurses' practice should be expanded, with greater emphasis on population health.

A Multifaceted Approach to Public Health Career and Professional Development Training.

The purpose of this article is to describe how a multifaceted approach to career and professional development training, focused on core competencies, student-driven programming, inter and multidisciplinary collaboration, and cultivating a community of insight and support, is being implemented by a university Public Health Career Services office with limited staff and resources and to share these practices for other public health programs to scale this approach to their own students' needs. The design of the career and professional development training program comprised five main approaches: (1) one-on-one career counseling, (2) peer-to-peer learning workshops, (3) community partnerships and experiential opportunities, (4) student-driven programming, and (5) accessible training and digital resources. All programs were tracked to gauge participation and to assess effectiveness. Noteworthy findings from program evaluations include (1) a large increase in student confidence levels in professionalism topics, from all of the school's departments; (2) benefits of student-driven programming and peer-to-peer learning, and (3) importance of employer and alumni engagement. Rather than use an optional participation model, it is recommended that a cohort model or mandatory participation be implemented as the opportunity to build on curriculum is vital.

State-Level Point-of-Sale Tobacco News Coverage and Policy Progression Over a 2-Year Period.

BACKGROUND: Mass media content may play an important role in policy change. However, the empirical relationship between media advocacy efforts and tobacco control policy success has rarely been studied. We examined the extent to which newspaper content characteristics (volume, slant, frame, source, use of evidence, and degree of localization) that have been identified as important in past descriptive studies were associated with policy progression over a 2-year period in the context of point-of-sale (POS) tobacco control. METHOD: We used regression analyses to test the relationships between newspaper content and policy progression from 2012 to 2014. The dependent variable was the level of implementation of state-level POS tobacco control policies at Time 2. Independent variables were newspaper article characteristics (volume, slant, frame, source, use of evidence, and degree of localization) and were collected via content analysis of the articles. State-level policy environment contextual variables were examined as confounders. RESULTS: Positive, significant bivariate relationships exist between characteristics of news content (e.g., high overall volume, public health source present, local quote and local angle present, and pro-tobacco control slant present) and Time 2 POS score. However, in a multivariate model controlling for other factors, significant relationships did not hold. DISCUSSION: Newspaper coverage can be a marker of POS policy progression. Whether media can influence policy implementation remains an important question. Future work should continue to tease out and confirm the unique characteristics of media content that are most associated with subsequent policy progression, in order to inform media advocacy efforts.

Organizational Supports for Research Evidence Use in State Public Health Agencies: A Latent Class Analysis.

OBJECTIVE: Use of research evidence in public health decision making can be affected by organizational supports. Study objectives are to identify patterns of organizational supports and explore associations with research evidence use for job tasks among public health practitioners. DESIGN: In this longitudinal study, we used latent class analysis to identify organizational support patterns, followed by mixed logistic regression analysis to quantify associations with research evidence use. SETTING: The setting included 12 state public health department chronic disease prevention units and their external partnering organizations involved in chronic disease prevention. PARTICIPANTS: Chronic disease prevention staff from 12 US state public health departments and partnering organizations completed self-report surveys at 2 time points, in 2014 and 2016 (N = 872). MAIN OUTCOME MEASURES: Latent class analysis was employed to identify subgroups of survey participants with distinct patterns of perceived organizational supports. Two classify-analyze approaches (maximum probability assignment and multiple pseudo-class draws) were used in 2017 to investigate the association between latent class membership and research evidence use. RESULTS: The optimal model identified 4 latent classes, labeled as "unsupportive workplace," "low agency leadership support," "high agency leadership support," and "supportive workplace." With maximum probability assignment, participants in "high agency leadership support" (odds ratio = 2.08; 95% CI, 1.35-3.23) and "supportive workplace" (odds ratio = 1.74; 95% CI, 1.10-2.74) were more likely to use research evidence in job tasks than "unsupportive workplace." The multiple pseudo-class draws produced comparable results with odds ratio = 2.09 (95% CI, 1.31-3.30) for "high agency leadership support" and odds ratio = 1.74 (95% CI, 1.07-2.82) for "supportive workplace." CONCLUSIONS: Findings suggest that leadership support may be a crucial element of organizational supports to encourage research evidence use. Organizational supports such as supervisory expectations, access to evidence, and participatory decision making may need leadership support as well to improve research evidence use in public health job tasks.

Developing Safe Syringe Exchange Programs: Role of the North Carolina Division of Public Health.

Syringe exchange programs became legal in North Carolina on July 11, 2016. A combination of forces led to this progressive public health measure, including advocacy of the State Health Official, in a state characterized by a conservative political climate. Data collected by the division of public health were a key contributor to the initiative. Nearly 5 North Carolinians died each day from unintentional medication or drug overdose. High rates of coinfection including hepatitis B and C, human immunodeficiency virus, and endocarditis were shown to have substantial economic consequences. The North Carolina Harm Reduction Coalition and use of Moral Foundations Theory in crafting messages were important in influencing legislation. North Carolina now has 30 active syringe exchange programs serving 40 counties. Individuals using intravenous drugs who take advantage of these syringe exchange programs are provided with clean needles to not only help prevent the spread of illness but also learn more about safe health practices.

Public health information in crisis-affected populations: a review of methods and their use for advocacy and action.

Valid and timely information about various domains of public health underpins the effectiveness of humanitarian public health interventions in crises. However, obstacles including insecurity, insufficient resources and skills for data collection and analysis, and absence of validated methods combine to hamper the quantity and quality of public health information available to humanitarian responders. This paper, the second in a Series of four papers, reviews available methods to collect public health data pertaining to different domains of health and health services in crisis settings, including population size and composition, exposure to armed attacks, sexual and gender-based violence, food security and feeding practices, nutritional status, physical and mental health outcomes, public health service availability, coverage and effectiveness, and mortality. The paper also quantifies the availability of a minimal essential set of information in large armed conflict and natural disaster crises since 2010: we show that information was available and timely only in a small minority of cases. On the basis of this observation, we propose an agenda for methodological research and steps required to improve on the current use of available methods. This proposition includes setting up a dedicated interagency service for public health information and epidemiology in crises.

Overachieving Municipalities in Public Health: A Machine-learning Approach.

BACKGROUND: Identifying successful public health ideas and practices is a difficult challenge towing to the presence of complex baseline characteristics that can affect health outcomes. We propose the use of machine learning algorithms to predict life expectancy at birth, and then compare health-related characteristics of the under- and overachievers (i.e., municipalities that have a worse and better outcome than predicted, respectively). METHODS: Our outcome was life expectancy at birth for Brazilian municipalities, and we used as predictors 60 local characteristics that are not directly controlled by public health officials (e.g., socioeconomic factors). RESULTS: The highest predictive performance was achieved by an ensemble of machine learning algorithms (cross-validated mean squared error of 0.168), including a 35% gain in comparison with standard decision trees. Overachievers presented better results regarding primary health care, such as higher coverage of the massive multidisciplinary program Family Health Strategy. On the other hand, underachievers performed more cesarean deliveries and mammographies and had more life-support health equipment. CONCLUSIONS: The findings suggest that analyzing the predicted value of a health outcome may bring insights about good public health practices.

Exploring the multidisciplinary extent of public health career structures in 12 countries: an exploratory mapping.

Background: While much is known about multidisciplinary public health (MDPH) professional practice in the UK which developed particularly in the 1990s, little is known about it in other settings especially low and middle-income countries (LMICs). This study reports on findings of a mapping review of public health career structures and an examination of how multidisciplinary they are in 12 countries. Methods: A 12-element template was used to collect data from relevant websites and key informants with public health experience in the 12 countries. Results: We found that while countries had similarities such as having MDPH professional organizations, there were differences in terms of public health specialty training programmes and openness of senior public health posts at various administrative levels to non-medical professionals. Conclusion: We conclude that there still gaps in MDPH career structures internationally. While this study provides preliminary knowledge on the subject, we recommend further research to inform debates and policies in MDPH professional practice especially in LMICs.

The public health evidence-base on novel psychoactive substance use: scoping review with narrative synthesis of selected bodies of evidence.

Background: This review aimed to address what was known about the public health burden associated with novel psychoactive substances (NPS) use, and the effectiveness of responses targeting NPS use and/or associated problems. Methods: Relevant literature was identified through a range of searches covering the period from January 2006 to June 2016. Data synthesis was undertaken in three stages. Firstly we mapped the evidence available in order to characterize the literature according to a set of analytic categories developed a priori. Secondly, we identified evidence gaps from a set of a priori research questions. Finally, we then undertook a narrative synthesis of selected bodies of evidence, interpreting data using a conceptual framework specifically designed for use in this review. Results: A total of 995 articles were included in the scoping review with the majority being case reports/series on individual level adverse effects due to NPS use. We synthesized UK data from 29 surveys and 7 qualitative studies, and international data in 10 systematic reviews on harms associated with NPS use, and 17 evaluations of policy responses. We found little data on risk factors, harms associated with long-term NPS use, and interventions. Conclusion: In all cases we found the available evidence to be at an early stage of development.

[Shortage of physicians in rural areas and in the public health service : A critical analysis of the evidence on the role of medical education and training]. / Ärztemangel in der hausärztlichen Versorgung auf dem Lande und im Öffentlichen Gesundheitsdienst : Eine kritische Analyse der Evidenz bezüglich der Rolle von Aus- und Weiterbildung.

BACKGROUND: A shortage of medical personnel has been seen for several decades in at least two sectors of the healthcare system: primary care in remote areas as well as medical care in the state public health departments (Öffentliches Gesundheitswesen). Strategies to reduce these problems are being sought. OBJECTIVE: This review examines the proposals, practical initiatives and empirical studies in under- and postgraduate medical education in order to estimate their potential impact on the solution of these problems. The analysis covers both Germany and Anglo-Saxon countries. MATERIALS AND METHODS: The study is based on a literature search in PubMed and Medline covering the last 20 years. With regard to Germany, programmatic documents and studies published in the German Journal of General Practice (Zeitschrift für Allgemeinmedizin) were also included. RESULTS AND DISCUSSION: Foreign empirical studies identify almost equal two factors with regard to primary care in remote areas: the recruitment of students from rural areas combined with special educational programs with a rural primary care orientation both in under- and postgraduate medical education. These programs should include several and longer practical working periods in primary care units and be well coordinated between the medical school and the local teaching physicians. As for the state public health sector, comparable initiatives are still lacking.

Yemen field epidemiology training programme: a tool for strengthening the public health workforce.

BACKGROUND: The shortage of skilled public health workers, especially epidemiologists, remains an important challenge for building effective public health systems in many low-income countries, including Yemen. To address this need, in 2011 the Ministry of Public Health and Population established the Yemen Field Epidemiology Training Programme (Y-FETP). AIMS: To describe the Y-FETP and its strengths and challenges in addressing Yemen's National Health System (NHS) needs. METHODS: We describe the structure and functions of the Y-FETPs and analyse the achievements and challenges of the first 7 years of programme implementation as they relate to the NHS. RESULTS: The Y-FETP is a postgraduate competency-based training with the objective of strengthening capacity in field epidemiology so that events of public health importance can be detected and investigated in a timely and effective manner. Since its establishment, the Y-FETP has successfully trained 30 health professionals in advanced field epidemiology. Furthermore, trainees investigated over 100 outbreaks, analysed and evaluated 95 surveillance systems, conducted 30 planned studies and presented 70 oral and poster presentations at national and international conferences. The main challenges are low retention of graduates by the NHS and financial unsustainability. CONCLUSIONS: The Y-FETP has strengthened the capacity of the Yemen health workforce and has been instrumental in supporting the NHS, especially during the war and the current crisis and health emergency as the security situation deteriorated and access to outside experts becomes limited. The programme provides a practical example of health systems strengthening through health workforce capacity development that can be replicated in countries with similar health workforce capacity challenges.
