Transmission of respiratory viruses when using public ground transport : a rapid review to inform public health recommendations during the COVID-19 pandemic

CITATION: Zhen, J. et al. 2020. Transmission of respiratory viruses when using public ground transport : a rapid review to inform public health recommendations during the COVID-19 pandemic. South African Medical Journal, 110(6), doi:10.7196/SAMJ.2020.v110i6.14751.The original publication is available at http://www.samj.org.zaIn response to the COVID-19 pandemic, numerous countries worldwide declared national states of emergency and implemented interventions to minimise the risk of transmission among the public. Evidence was needed to inform strategies for limiting COVID-19 transmission on public transport. On 20 March 2020, we searched MEDLINE, CENTRAL, Web of Science and the World Health Organization’s database of ‘Global research on coronavirus disease (COVID-19)’ to conduct a rapid review on interventions that reduce viral transmission on public ground transport. After screening 74 records, we identified 4 eligible studies. These studies suggest an increased risk of viral transmission with public transportation use that may be reduced with improved ventilation. International and national guidelines suggest the following strategies: keep the public informed, stay at home when sick, and minimise public transport use. Where use is unavoidable, environmental control, respiratory etiquette and hand hygiene are recommended, while a risk-based approach needs to guide the use of non-medical masks.http://www.samj.org.za/index.php/samj/article/view/12943Publisher's versio

Household evacuation characteristics in American Samoa during the 2009 Samoa Islands tsunami

Tsunamis represent significant threats to human life and development in coastal communities. This quantitative study examines the influence of household characteristics on evacuation actions taken by 211 respondents in American Samoa who were at their homes during the 29 September 2009 Mw 8.1 Samoa Islands earthquake and tsunami disaster. Multiple logistic regression analysis of survey data was used to examine the association between evacuation and various household factors. Findings show that increases in distance to shoreline were associated with a slightly decreased likelihood of evacuation, whereas households reporting higher income had an increased probability of evacuation. The response in American Samoa was an effective one, with only 34 fatalities in a tsunami that reached shore in as little as 15 minutes. Consequently, future research should implement more qualitative study designs to identify event and cultural specific determinants of household evacuation behaviour to local tsunamis

Are US degree-granting institutions associated with better community health determinants and outcomes?

Objectives: The impact of individual education level on health outcomes is well-established, but the effect of degree-granting institutions on county health rankings (CHRs) is unknown. The objective of this study is to determine if there is an association between the presence of degree-granting institutions and CHRs. Study design: This is an ecologic study. Methods: Data for 3062 counties were derived from the Robert Wood Johnson County Health Rankings and the Integrated Postsecondary Education Data System for year 2016. Ordinal logistic regression was utilized to determine the association between presence of a degree-granting institution and county rankings for health behaviors, health outcomes, clinical care, social and economic factors, and physical environment. All models were adjusted for potential confounding factors including age, sex, race/ethnicity, English language proficiency, and urban/rural location. Results: The presence of a degree-granting institution was positively associated with CHRs for length of life (odds ratio [OR] = 1.28; 95% confidence interval [CI]: 1.05, 1.58), health behaviors (OR = 1.46; 95% CI: 1.19, 1.79), and clinical care (OR = 1.36; 95% CI: 1.11, 1.67). Counties with the highest rankings in one health category were more likely to score in the highest rankings for other health categories. Conclusions: These findings suggest that degree-granting institutions are associated with CHRs. Partnerships between public health agencies and degree-granting institutions are recommended to improve population health

The influence of community health on hospitals attainment of Magnet designation: Implications for policy and practice

Aims: To determine if there is an association between better County Health Rankings and the increased odds of a hospital gaining Magnet designation in subsequent years (2014–2019) compared with counties with lower rankings. Background: The Magnet hospital model is recognized to have a great effect on nurses, patients and organizational outcomes. Although Magnet hospital designation is a well-established structural marker for nursing excellence, the effect of County Health Rankings and subsequent hospital achievement of Magnet status is unknown. Design: A descriptive, cross-sectional quantitative approach was adopted for this study. Methods: Data were derived from 2010 to 2019 U.S. County Health Rankings, American Hospital Association, and American Nursing Credentialing Center databases. Logistic regression models were utilized to determine associations between county rankings for health behaviours, clinical care, social and economic factors, physical environment and counties with a new Magnet hospital after 2014. Results: Counties with the worst rankings for clinical care and socio-economic status had reduced odds of obtaining a Magnet hospital designation compared with best-ranking counties. While middle-ranking counties for the physical environment ranking had increased odds of having Magnet designation compared with best-ranking counties. Additionally, having an increased percent of government non-federal hospital or a higher percentage of critical access hospitals in the county reduced the odds of having a Magnet-designated facility after 2014. Conclusion: The findings underscore the important associations between Magnet-designated facilities’ location and the health of its surrounding counties. This study is the first to examine the relationship between County Health Rankings and a hospital\u27s likelihood of obtaining Magnet status and points to the need for future research to explore outcomes of care previously identified as improved in Magnet-designated hospitals. Implications: Recognizing the benefits of Magnet facilities, it is important for health care leaders and policy makers to seek opportunities to promote centres of excellence in higher need communities through policy and financial intervention

Factors Affecting Household Adoption of an Evacuation Plan in American Samoa After the 2009 Earthquake and Tsunami.

American Samoa is still recovering from the debilitating consequences of the September 29, 2009 tsunami. Little is known about current household preparedness in American Samoa for future earthquakes and tsunamis. Thus, this study sought to enumerate the number of households with an earthquake and tsunami evacuation plan and to identify predictors of having a household evacuation plan through a post-tsunami survey conducted in July 2011. Members of 300 households were interviewed in twelve villages spread across regions of the principle island of Tutuila. Multiple logistic regression showed that being male, having lived in one\u27s home for \u3c 30 years, and having a friend who suffered damage to his or her home during the 2009 tsunami event increased the likelihood of having a household evacuation plan. The prevalence of tsunami evacuation planning was 35% indicating that survivors might feel that preparation is not necessary given effective adaptive responses during the 2009 event. Results suggest that emergency planners and public health officials should continue with educational outreach to families to spread awareness around the importance of developing plans for future earthquakes and tsunamis to help mitigate human and structural loss from such natural disasters. Additional research is needed to better understand the linkages between pre-event planning and effective evacuation responses as were observed in the 2009 events
