Sociodemographic determinants of digital health literacy: A systematic review and meta-analysis.

INTRODUCTION: Differences in digital health literacy levels are associated with a lack of access to digital tools, usage patterns, and the ability to effectively use digital technologies. Although some studies have investigated the impact of sociodemographic factors on digital health literacy, a comprehensive evaluation of these factors has not been conducted. Therefore, this study sought to examine the sociodemographic determinants of digital health literacy by conducting a systematic review of the existing literature. METHODS: A search of four databases was conducted. Data extraction included information on study characteristics, sociodemographic factors, and the digital health literacy scales used. Meta-analyses for age and sex were conducted using RStudio software with the metaphor package. RESULTS: A total of 3922 articles were retrieved, of which 36 were included in this systematic review. Age had a negative effect on digital health literacy (B = -0.05, 95%CI [-0.06; -0.04]), particularly among older adults, whereas sex appeared to have no statistically significant influence among the included studies (B = - 0.17, 95%CI [-0.64; 0.30]). Educational level, higher income, and social support also appeared to have a positive influence on digital health literacy. DISCUSSION: This review highlighted the importance of addressing the digital health literacy needs of underprivileged populations, including immigrants and individuals with low socioeconomic status. It also emphasizes the need for more research to better understand the influence of sociodemographic, economic, and cultural differences on digital health literacy. CONCLUSIONS: Overall, this review suggests digital health literacy is dependent on sociodemographic, economic, and cultural factors, which may require tailored interventions that consider these nuances.

Insights on COVID-19 Vaccination in Portugal: A Qualitative Study among Health Professionals and Teachers.

BACKGROUND: Vaccination against COVID-19 has had a major impact over the course of the pandemic, leading to a reduced number of hospitalizations and deaths. However, the mass vaccination process has been accompanied by skepticism and hesitancy since its beginning. As health professionals and teachers are important public health actors who can strongly intervene to reduce vaccination hesitancy among their patients and students, respectively, this study aimed to assess their main perceptions towards COVID-19 vaccination. METHODS: Two focus group sessions, one with health professionals and the other with teachers, were conducted according to the COREQ checklist. Qualitative data were analyzed through theoretical thematic analysis. RESULTS: In general, none of the groups showed vaccine hesitancy, although both groups had concerns regarding the safety and efficacy of the vaccines. The main concerns of health professionals were mostly related to the long-term impact of the COVID-19 pandemic, while teachers were more worried about the lack of access to reliable information about the COVID-19 vaccination. CONCLUSIONS: It is plausible to conclude that it is imperative to provide clear and accurate information for the population in order to avoid vaccination hesitancy.

Educational Interventions to Reduce Prescription and Dispensing of Antibiotics in Primary Care: A Systematic Review of Economic Impact.

Antibiotic resistance remains a crucial global public health problem with excessive and inappropriate antibiotic use representing an important driver of this issue. Strategies to improve antibiotic prescription and dispensing are required in primary health care settings. The main purpose of this review is to identify and synthesize available evidence on the economic impact of educational interventions to reduce prescription and dispensing of antibiotics among primary health care professionals. Information about the clinical impact resulting from the implementation of interventions was also gathered. PubMed, Scopus, Web of Science and EMBASE were the scientific databases used to search and identify relevant studies. Of the thirty-three selected articles, most consisted of a simple intervention, such as a guideline implementation, while the others involved multifaceted interventions, and differed regarding study populations, designs and settings. Main findings were grouped either into clinical or cost outcomes. Twenty of the thirty-three articles included studies reporting a reduction in outcome costs, namely in antibiotic cost and associated prescription costs, in part due to an overall improvement in the appropriateness of antibiotic use. The findings of this study show that the implementation of educational interventions is a cost-effective strategy to reduce antibiotic prescription and dispensing among primary healthcare providers.

Unravelling the drivers behind COVID-19 vaccination hesitancy and refusal among teachers: A nationwide study.

This study aims to assess the determinants of the coronavirus disease 2019 (COVID-19) vaccination hesitancy and refusal (VHR) among teachers, from pre-school to higher education, through an online survey. A logistic regression analysis was used to determine the adjusted odds ratio (OR) of the independent variables (perceptions, knowledge, and attitudes) per 1-point increase in the Likert scale, and VHR. Concerns about the vaccines' efficacy and safety increase the risk of VHR (OR = 6.97, 95 %CI: 4.82-10.09 and OR = 8.71, 95 %CI: 5.52-13.73, respectively). Higher risk perceptions of getting infected (1/OR = 3.94, 95 %CI: 2.93-5.29), trust in the effectiveness of vaccines in reducing this risk or protecting against suffering complications (OR = 3.52, 95 %CI: 2.72-4.55 and OR = 10.94, 95 %CI: 7.16-16.68, respectively), and higher trust levels on the information transmitted regarding COVID-19 vaccination, are associated to lower VHR. As VHR appears to be highly influenced by perceptions, knowledge, and attitudes, it is crucial to promote and design interventions targeted to transforming these determinants.

eHealthResp, a Digital Intervention to Improve Antibiotic Prescribing in Respiratory Infections: A Pilot Study.

The emergence of antibiotic resistance (ABR) is one of the most serious public health threats worldwide. The inappropriate use of antibiotics is considered the main determinant for the increase and development of ABR, contributing to a greater risk of therapeutic ineffectiveness, particularly within primary care context. Therefore, this pilot study aims to raise awareness and promote an adequate antibiotic use among physicians, through the evaluation of the eHealthResp platform, a digital intervention composed by an online course and a mobile application, to aid in the management of respiratory tract infections. The global validation of the eHealthResp platform was carried out by 12 physicians who explored and performed a quantitative and qualitative evaluation of the contents of the online course and mobile app. The global evaluation of the analyzed parameters was very positive, with the highest median scores being attributed to adequacy, correction, format, and trust of the eHealthResp platform. The qualitative feedback enhanced the contents' relevance, clarity, and consolidation, as well as the effectiveness of the educational intervention against ABR. Overall, this study revealed that the eHealthResp may be regarded as an important e-health tool for the management of respiratory tract infections and improvement of antibiotic prescription practices among physicians.

Improving Pharmacists' Awareness of Inadequate Antibiotic Use for URTIs through an Educational Intervention: A Pilot Study.

The inadequate use of antibiotics led to the development of multi-resistant bacteria that are now causing millions of deaths worldwide. Since most antibiotics are prescribed/dispensed to treat respiratory tract infections, it is important to raise awareness among health professionals to optimize antibiotic use, especially within the primary care context. Thus, this pilot study aimed to evaluate pharmacists' feedback about the eHealthResp platform, composed by an online course and a mobile application (app) to help in the management of upper respiratory tract infections (URTIs). Ten community pharmacists were invited to participate in this study, exploring the contents of the eHealthResp platforms and answering a content validation questionnaire composed by eight qualitative and thirty-five quantitative questions about the online course and mobile app. The eHealthResp platform is a comprehensive, consistent, and high-quality e-learning tool. Median scores of 5.00 were attributed to the course contents' and clinical cases' adequacy and correction. Most qualitative feedback was about completeness and objectivity of the course, and its usefulness for clinical practice. This study showed that eHealthResp has great potential as an e-health tool for the management of URTIs' symptoms, which may ultimately aid in reducing inappropriate antibiotic use.

A roadmap for the development and evaluation of the eHealthResp online course.

Background: Inappropriate antibiotic use constitutes one of the most concerning public health issues, being one of the main causes of antibiotic resistance. Hence, to tackle this issue, it is important to encourage the development of educational interventions for health practitioners, namely by using digital health tools. This study focuses on the description of the development and validation process of the eHealthResp online course, a web platform directed to physicians and pharmacists, with the overall goal of improving antibiotic use for respiratory tract infections, along with the assessment of its usability. Methods: The eHealthResp platform and the courses, developed with a user-centered design and based on Wordpress and MySQL, were based on a previously developed online course. A questionnaire to assess the usability was distributed among physicians (n = 6) and pharmacists (n = 6). Based on the obtained results, statistical analyses were conducted to calculate the usability score and appraise the design of the online course, as well as to compare the overall scores attributed by both groups. Further qualitative comments provided by the participants have also been analyzed. Results: The eHealthResp contains two online courses directed to physicians and pharmacists aiming to aid in the management of respiratory tract infections. The average usability score of the eHealthResp online courses for physicians and pharmacists was of 78.33 (±11.57, 95%CI), and 83.75 (±15.90, 95%CI), respectively. Qualitative feedback emphasized the usefulness of the course, including overall positive reviews regarding user-friendliness and consistency. Conclusions: This study led us to conclude that the eHealthResp online course is not recognized as a complex web platform, as both qualitative and quantitative feedback obtained were globally positive.

What determines health professionals' COVID-19 vaccine hesitancy? A nationwide study.

INTRODUCTION: To contain the COVID-19 pandemic, higher vaccination rates are essential. However, as vaccine hesitancy is a reality, it is important to understand what drives health professionals to refuse getting vaccinated against COVID-19, who have been in the frontline of this pandemic since its beginning and may be key actors to improve vaccine coverage among their patients. PURPOSE: This study aims to assess the factors associated with vaccine hesitancy (VH) among health professionals (physicians, nurses, pharmacists and dentists). METHODS: A nationwide cross-sectional study was conducted through an online survey, with 890 Portuguese health professionals. A logistic regression analysis was used to determine the adjusted odds ratio (OR) of the independent variables (perceptions, knowledge and attitudes) per 1-point increase in the Likert scale and VH. RESULTS: Complacency, communications, confidence and convenience were strongly associated with VH probability. Concerns about vaccines' efficacy (ORPhysicians  = 8.33, 95% CI: 4.51-15.36) and safety (ORNurses  = 11.07, 95% CI: 4.12-29.77) increase the risk of VH on all health professional groups. A reduction of VH probability is associated with higher risk perceptions of getting infected (1/ORNurses  = 2.76, 95% CI: 1.52-5.02) and suffering complications (1/ORNurses  = 33.72, 95% CI: 8.48-134.13), higher confidence in the effectiveness of COVID-19 vaccines (1/ORDentists  = 12.29, 95% CI: 2.91-51.89), risk perception of getting infected if vaccinated (1/ORPhysicians  = 14.92, 95% CI: 6.85-32.50), risk of suffering from complications after getting vaccinated, and higher trust levels on the information transmitted by competent authorities (1/ORDentists  = 17.76, 95% CI: 3.83-82.22). CONCLUSIONS: To reduce COVID-19 VH, which appears to be highly influenced by perceptions, knowledge and attitudes, it is essential to promote interventions directed to transforming these potentially modifiable determinants.

The Effect of Nutrition on Aging-A Systematic Review Focusing on Aging-Related Biomarkers.

Despite the increasing life expectancy, an individual's later years tends to be accompanied by a decrease in the quality of life. Though biological changes that occur through the natural process of aging cannot be controlled, the risk factors associated with lifestyle can. Thus, the main goal of this systematic review was to evaluate how nutrition can modulate aging. For this purpose, thirty-six studies were selected on (i) the efficiency of nutrition's effect on aging, (ii) the evaluation of biomarkers that promote healthy aging, and (iii) how to increase longevity through nutrition, and their quality was assessed. The results showed that choosing low carbohydrate diets or diets rich in vegetables, fruits, nuts, cereals, fish, and unsaturated fats, containing antioxidants, potassium, and omega-3 decreased cardiovascular diseases and obesity risk, protected the brain from aging, reduced the risk of telomere shortening, and promoted an overall healthier life. With this study, the conclusion is that since the biological processes of aging cannot be controlled, changing one's nutritional patterns is crucial to prevent the emergence and development of diseases, boost longevity, and, mostly, to enhance one's quality of life and promote healthy aging.

Perceptions, knowledge and attitudes about COVID-19 vaccine hesitancy in older Portuguese adults.

BACKGROUND: Coronavirus 2019 (COVID-19) has become a public-health emergency of international concern. Most efforts to contain the spread and transmission of the virus rely on campaigns and interventions targeted to reduce Vaccine Hesitancy and Refusal (VHR). OBJECTIVE: this study aims to assess the major factors associated with VHR in the older population in Portugal. METHODS: a nation-wide cross-sectional study was conducted in the older Portuguese population (≥65 years old) through computer-assisted telephone interviewing. Logistic regression was used to determine the adjusted odds ratio (OR) of the independent variables (perceptions, knowledge and attitudes) and of the outcome (VHR). RESULTS: the response rate was 60.1% (602/1,001). Perceptions, knowledge and attitudes were strongly associated with VHR probability. A 1-point Likert scale increase in concerns about the vaccines' efficacy and safety increased the risk of VHR by 1.96 (95% confidence interval [CI]: 1.40-6.28) and 3.13 (95%CI: 2.08-8.22), respectively. A reduction of VHR probability for 'reliability of the information released by social media' (OR = 0.34, 95%CI: 0.16-0.70) and for 'trust in national and international competent authorities' (OR = 0.34, 95%CI: 0.17-0.69) is also observed per 1-point increase. CONCLUSIONS: as VHR seems to be strongly associated with perceptions, knowledge and attitudes, the design and promotion of vaccination campaigns/educational interventions specifically targeted at changing these potentially modifiable determinants may help to tackle COVID-19 VHR and achieve a wider vaccine coverage.

Prescription of anxiolytics, sedatives, hypnotics and antidepressants in outpatient, universal care during the COVID-19 pandemic in Portugal: a nationwide, interrupted time-series approach.

BACKGROUND: The COVID-19 pandemic has had a significant impact on the population's mental health. However, its impact on the consumption of anxiolytics, sedatives, hypnotics and antidepressants remains to be evaluated. Hence, this article aims to assess the prescription trends of these drugs in Portugal, from January 2018 to March 2021, while critically examining whether the COVID-19 pandemic had an impact on these prescription trends or not. METHODS: A nationwide interrupted time-series analysis of the prescription data of anxiolytics, sedatives, hypnotics and antidepressants in outpatient setting of the public health sector was conducted. The data encompassed the defined daily dose per month, age range and sex and were analysed following a segmented regression approach. RESULTS: The pandemic preceded an immediate reduction in the prescription of anxiolytics, sedatives and hypnotics for children and adolescents. However, an increasing trend throughout the pandemic has been noted in the prescription of these drugs, especially among adults aged 65 years or above. A drop in antidepressant prescription was observed as an immediate effect of the pandemic among male and female adolescents and elderly women. From March 2020 to March 2021, a decreasing prescription trend has been noted among men. CONCLUSIONS: When analysing specific genders and age ranges, differences can be noted, in terms of both immediate impact and prescribing trends throughout 1 year of the COVID-19 pandemic. The impact of the pandemic on mental health and its association with the consumption trends of psychoactive drugs, and with the access to mental health treatments, should be further assessed.

The Impact of the COVID-19 Pandemic on Antibiotic Prescribing Trends in Outpatient Care: A Nationwide, Quasi-Experimental Approach.

Coronavirus disease 2019 (COVID-19) has spread globally and is currently having a damaging impact on nearly all countries in the world. The implementation of stringent measures to stop COVID-19 dissemination had an influence on healthcare services and associated procedures, possibly causing antibiotic consumption fluctuations. This paper aims to evaluate the immediate and long-term impact of the COVID-19 pandemic on antibiotic prescribing trends in outpatient care of the Portuguese public health sector, including in primary healthcare centers and hospitals, as well as on specific antibiotic groups known to be closely associated with increased resistance. Segmented regression analysis with interrupted time series data was used to analyze whether the COVID-19 pandemic had an impact in antibiotic prescribing tendencies at a national level. The outcomes from this quasi-experimental approach demonstrate that, at the beginning of the pandemic, a significant, immediate decrease in the overall antibiotic prescribing trends was noticed in the context of outpatient care in Portugal, followed by a statistically non-significant fall over the long term. The data also showed a significant reduction in the prescription of particular antibiotic classes (antibiotics from the Watch group, 3rd-generation cephalosporins, fluoroquinolones, and clarithromycin) upon COVID-19 emergence. These findings revealed an important disruption in antibiotics prescribing caused by the current public health emergency.

Comparing Hospital and Primary Care Physicians' Attitudes and Knowledge Regarding Antibiotic Prescribing: A Survey within the Centre Region of Portugal.

BACKGROUND: Antibiotic resistance is a worldwide public health problem, leading to longer hospital stays, raising medical costs and mortality levels. As physicians' attitudes are key factors to antibiotic prescribing, this study sought to explore their differences between primary care and hospital settings. METHODS: A survey was conducted between September 2011 and February 2012 in the center region of Portugal in the form of a questionnaire to compare hospital (n = 154) and primary care (n = 421) physicians' attitudes and knowledge regarding antibiotic prescribing. RESULTS: More than 70% of the attitudes were statistically different (p < 0.05) between hospital physicians (HPs) and primary care physicians (PCPs). When compared to PCPs, HPs showed higher agreement with antibiotic resistances being a public health problem and ascribed more importance to microbiological tests and to the influence of prescription on the development of resistances. On the other hand, PCPs tended to agree more regarding the negative impact of self-medication with antibiotics dispensed without medical prescription and the need for rapid diagnostic tests. Seven out of nine sources of knowledge's usefulness were statistically different between both settings, with HPs considering most of the knowledge sources to be more useful than PCPs. CONCLUSIONS: Besides the efforts made to improve both antibiotic prescribing and use, there are differences in the opinions between physicians working in different settings that might impact the quality of antibiotic prescribing. In the future, these differences must be considered to develop more appropriate interventions.

Validation of the eHealthResp online course for pharmacists and physicians: A Delphi method approach.

FRAMEWORK: The inappropriate use of antibiotics for respiratory tract infections is dispersed worldwide, thus being a strong contributor to antibiotic resistances. As the use of educational interventions among health practitioners is shown to have an impact on judicious antibiotic use, an online course (eHealthResp) has been developed, especially targeted to pharmacists and physicians. Thus, the main goal of this study is to validate the contents of the online course eHealthResp. METHODS: This two-round Delphi study involved the recruitment of a multidisciplinary panel (n = 19), to which the questionnaires of the first round were sent. After the first round, a report summing up the results has been forwarded to the panel, along with a new, reformulated version of the questionnaire. RESULTS: After the two rounds of the Delphi process, consensus was evaluated. Six clinical cases and fifty-one treatments obtained minor consensus [60-75%] or full consensus (≥75%). The question on antibiotic practice has obtained a consensus >90% on both rounds. CONCLUSIONS: The validation of the contents based on experts' consensus has been an essential approach to improve eHealthResp's online course, as valuable feedback has been provided by the panel on both rounds.

The Use of Antidepressants, Anxiolytics, Sedatives and Hypnotics in Europe: Focusing on Mental Health Care in Portugal and Prescribing in Older Patients.

(1) Background: Mental disorders are a growing concern in the 21st century. The most prevalent common mental disorders include depression and anxiety. It is predicted that half of the population will at some point in their lives experience one or more mental disorders. Although common mental disorders are highly prevalent, some of the most significant related problems are the wide treatment gap and the excessive use of antidepressants, anxiolytics and sedatives/hypnotics, especially among older patients. (2) Methods: This study aimed to analyze mental health care in Portugal, with a focus on the consumption of antidepressants, anxiolytics, sedatives and hypnotics among older patients. (3) Results: The use of antidepressants, anxiolytics, sedatives and hypnotics has increased overall across Europe. In Portugal, a downward trend of sedatives and hypnotics consumption can be observed. Anxiolytics and antidepressants, on the other hand, have been increasing. Patients aged ≥60 years old consume more than half of the aforementioned drugs. (4) Conclusions: Mental health policies should be designed to improve the conscientious use of antidepressants, anxiolytics, sedatives and hypnotics, particularly among older adults.

E-Health Tools to Improve Antibiotic Use and Resistances: A Systematic Review.

(1) Background: e-Health tools, especially in the form of clinical decision support systems (CDSSs), have been emerging more quickly than ever before. The main objective of this systematic review is to assess the influence of these tools on antibiotic use for respiratory tract infections. (2) Methods: The scientific databases, MEDLINE-PubMed and EMBASE, were searched. The search was conducted by two independent researchers. The search strategy was mainly designed to identify relevant studies on the effectiveness of CDSSs in improving antibiotic use, as a primary outcome, and on the acceptability and usability of CDSSs, as a secondary outcome. (3) Results: After the selection, 22 articles were included. The outcomes were grouped either into antibiotics prescription practices or adherence to guidelines concerning antibiotics prescription. Overall, 15 out of the 22 studies had statistically significant outcomes related to the interventions. (4) Conclusions: Overall, the results show a positive impact on the prescription and conscientious use of antibiotics for respiratory tract infections, both with respect to patients and prescribing healthcare professionals. CDSSs have been shown to have great potential as powerful tools for improving both clinical care and patient outcomes.
