What have we learned about communication inequalities during the H1N1 pandemic: a systematic review of the literature.

ABSTRACT:

Background

During public health emergencies, public officials are busy in developing communication strategies to protect the population from existing or potential threats. However, a population's social and individual determinants (i.e. education, income, race/ethnicity) may lead to inequalities in individual or group-specific exposure to public health communication messages, and in the capacity to access, process, and act upon the information received by specific sub-groups- a concept defined as communication inequalities.The aims of this literature review are to: 1) characterize the scientific literature that examined issues related to communication to the public during the H1N1 pandemic, and 2) summarize the knowledge gained in our understanding of social determinants and their association with communication inequalities in the preparedness and response to an influenza pandemic.

Methods

Articles were searched in eight major communication, social sciences, and health and medical databases of scientific literature and reviewed by two independent reviewers by following the PRISMA guidelines. The selected articles were classified and analyzed in accordance with the Structural Influence Model of Public Health Emergency Preparedness Communications.

Results

A total of 118 empirical studies were included for final review. Among them, 78% were population-based studies and 22% were articles that employed information environment analyses techniques. Consistent results were reported on the association between social determinants of communication inequalities and emergency preparedness outcomes. Trust in public officials and source of information, worry and levels of knowledge about the disease, and routine media exposure as well as information-seeking behaviors, were related to greater likelihood of adoption of recommended infection prevention practices. When addressed in communication interventions, these factors can increase the effectiveness of the response to pandemics.

Conclusions

Consistently across studies, a number of potential predictors of behavioral compliance to preventive recommendations during a pandemic were identified. Our findings show the need to include such evidence found in the development of future communication campaigns to ensure the highest rates of compliance with recommended protection measures and reduce communication inequalities during future emergencies.

Project description:To systematically evaluate the effect of extracorporeal membrane oxygenation on survival in adults with acute respiratory failure and to help inform institutional decisions about implementing an extracorporeal membrane oxygenation program or transferring patients to experienced extracorporeal membrane oxygenation centers during the H1N1 influenza pandemic.National Guideline Clearinghouse, MEDLINE, EMBASE, Agency for Healthcare Research and Quality Evidence-based Practice reports, National Institute for Health and Clinical Excellence, Cochrane Library, International Network of Agencies for Health Technology Assessment, and citation review.Studies of extracorporeal membrane oxygenation in adult acute respiratory failure, reporting mortality rates for at least 10 patients in extracorporeal membrane oxygenation and nonextracorporeal membrane oxygenation groups.Mortality rates were abstracted for all patients and for patients with influenza. Risk ratios were meta-analyzed using random-effects methods and assessed for heterogeneity.There are no evidence-based clinical guidelines on the use of extracorporeal membrane oxygenation in patients with influenza. Three randomized controlled trials and three cohort studies evaluated extracorporeal membrane oxygenation in patients with acute respiratory failure; none reported specifically on patients with influenza. Meta-analysis of the randomized controlled trials revealed significant heterogeneity in risk of mortality. The summary risk ratio found by the meta-analysis was 0.93 (95% confidence interval, 0.71 to 1.22). The most recent trial found a reduction in mortality and severe disability at 6 months among patients in whom extracorporeal membrane oxygenation was considered. Observational studies suggest that extracorporeal membrane oxygenation for acute respiratory failure resulting from viral pneumonia is associated with improved mortality compared with other etiologies of acute respiratory failure.The best evidence to guide decisions regarding the use of extracorporeal membrane oxygenation for patients with influenza stems from trials of extracorporeal membrane oxygenation for acute respiratory failure of all etiologies, among which significant heterogeneity exists, and from case series describing outcomes of extracorporeal membrane oxygenation in patients with influenza. Thus, there is insufficient evidence to provide a recommendation for extracorporeal membrane oxygenation use among patients with respiratory failure resulting from influenza. However, clinicians should consider extracorporeal membrane oxygenation within the context of other salvage therapies for acute respiratory failure.

Project description:AimTo collect, organize and appraise evidence of socioeconomic and demographic inequalities in health and mortality among the older population using a summary measure of population health: Health Expectancy.MethodsA systematic literature review was conducted. Literature published in English before November 2014 was searched via two possible sources: three electronic databases (Web of Science, Medline and Embase), and references in selected articles. The search was developed combining terms referring to outcome, exposure and participants, consisting in health expectancy, socioeconomic and demographic groups, and older population, respectively.ResultsOf 256 references identified, 90 met the inclusion criteria. Six references were added after searching reference lists of included articles. Thirty-three studies were focused only on gender-based inequalities; the remaining sixty-three considered gender along with other exposures. Findings were organized according to two leading perspectives: the type of inequalities considered and the health indicators chosen to measure health expectancy. Evidence of gender-based differentials and a socioeconomic gradient were found in all studies. A remarkable heterogeneity in the choice of health indicators used to compute health expectancy emerged as well as a non-uniform way of defining same health conditions.ConclusionsHealth expectancy is a useful and convenient measure to monitor and assess the quality of ageing and compare different groups and populations. This review showed a general agreement of results obtained in different studies with regard to the existence of inequalities associated with several factors, such as gender, education, behaviors, and race. However, the lack of a standardized definition of health expectancy limits its comparability across studies. The need of conceiving health expectancy as a comparable and repeatable measure was highlighted as fundamental to make it an informative instrument for policy makers.

Project description:BackgroundThe COVID-19 pandemic impacted how people accessed health services and likely how they managed chronic conditions such as type 2 diabetes (T2D). Social media forums present a source of qualitative data to understand how adaptation might have occurred from the perspective of the patient.ObjectiveOur objective is to understand how the care-seeking behaviors and attitudes of people living with T2D were impacted during the early part of the pandemic by conducting a scoping literature review. A secondary objective is to compare the findings of the scoping review to those presented on a popular social media platform Reddit.MethodsA scoping review was conducted in 2021. Inclusion criteria were population with T2D, studies are patient-centered, and study objectives are centered around health behaviors, disease management, or mental health outcomes during the COVID-19 pandemic. Exclusion criteria were populations with other noncommunicable diseases, examining COVID-19 as a comorbidity to T2D, clinical treatments for COVID-19 among people living with T2D, genetic expressions of COVID-19 among people living with T2D, gray literature, or studies not published in English. Bias was mitigated by reviewing uncertainties with other authors. Data extracted from the studies were classified into thematic categories. These categories reflect the findings of this study as per our objective. Data from the Reddit forums related to T2D from March 2020 to early March 2021 were downloaded, and support vector machines were used to classify if a post was published in the context of the pandemic. Latent Dirichlet allocation topic modeling was performed to gather topics of discussion specific to the COVID-19 pandemic.ResultsA total of 26 studies conducted between February and September 2020, consisting of 13,673 participants, were included in this scoping literature review. The studies were qualitative and relied mostly on qualitative data from surveys or questionnaires. Themes found from the literature review were "poorer glycemic control," "increased consumption of unhealthy foods," "decreased physical activity," "inability to access medical appointments," and "increased stress and anxiety." Findings from latent Dirichlet allocation topic modeling of Reddit forums were "Coping With Poor Mental Health," "Accessing Doctor & Medications and Controlling Blood Glucose," "Changing Food Habits During Pandemic," "Impact of Stress on Blood Glucose Levels," "Changing Status of Employment & Insurance," and "Risk of COVID Complications."ConclusionsTopics of discussion gauged from the Reddit forums provide a holistic perspective of the impact of the pandemic on people living with T2D, which were found to be comparable to the findings of the literature review. The study was limited by only having 1 reviewer for the literature review, but biases were mitigated by consulting authors when there were uncertainties. Qualitative analysis of Reddit forms can supplement traditional qualitative studies of the behaviors of people living with T2D.
