RESUMO

Academic social contexts and educational beliefs may influence teaching practices and teaching intentions. Insight into such beliefs represents an important source of information for medical schools to improve the quality of teaching and to guide content of faculty development programs. The aim of this study was to explore beliefs about teaching among prospective clinical teachers at a newly established medical school in Southern Switzerland and to estimate the relationship between these beliefs and intention to commit to teaching in the newly established medical curriculum using Fishbein's integrative model of behaviour prediction. We targeted a purposive sample of physicians working in hospital departments potentially involved in the clinical immersion of medical students enrolled in the program. We designed a cross-sectional quantitative study using an online questionnaire. The questionnaire included both items developed by the authors and items belonging to a previously validated questionnaire. Participants showed a high intention to commit to teaching in the newly established curriculum. We found that self-efficacy beliefs and two sets of behavioural beliefs, namely perceived importance and expectations, had a positive correlation with the intention to commit. On the other hand, we pointed out a number of normative beliefs that in the long run could hinder the maintenance of this commitment, which should be addressed both at the levels of both faculty development and institutional policy rules. Our study also highlights the importance of reinforcing teachers' perceived self-efficacy in providing clinical supervision, strengthening their perceived importance of the clinical supervision, and incentivising the commitment of teachers by ensuring they have protected time to devote to this activity.

RESUMO

AIMS: Undue concerns about the consequences of fever and its inappropriate management have been documented worldwide among physicians. However, no data exist on medical students. We investigated the perception, knowledge and attitude towards childhood fever among final-year medical students. METHODS: Between June and September 2021, final-year medical students of six Italian universities were invited to complete an online survey on their conceptions and attitude towards pharmacological and non-pharmacological management of childhood fever. History of relevant personal or second-hand experience with childhood fever was also addressed. Both quantitative and qualitative approaches were used. RESULTS: Of 1095 (69%) final-year medical students, 756 completed the survey. Many students believe that high fever might cause brain damage, would recommend physical methods and alternate two drugs for fever. Most students do not think that fever has mainly beneficial effects. In Northern Italy, students are less likely to believe that fever might lead to brain damage (OR 0.55, 95% CI 0.33-0.94), and in Southern Italy students are more likely to advise physical methods (OR 1.77, 95% CI 1.22-2.57) and less likely to believe that fever has mainly beneficial effects (OR 0.55, 95% CI 0.39-0.77). History of a relevant personal episode of fever during childhood was not associated with these outcomes. CONCLUSIONS: Misconceptions about fever are common among final-year medical students in Italy. Cultural factors rather than individually learned traits might underlie these beliefs. Medical students are a promising target for educational interventions to improve childhood fever management.

RESUMO

Despite the availability of clinical guidelines on the correct symptomatic management of fever in children, several studies have reported inaccurate knowledge about this symptom and inappropriate management behaviours among caregivers. There is evidence that caregivers' management of fever is largely influenced by unrealistic and unwarranted concerns about the potential harm that elevated body temperature can cause, a phenomenon commonly referred to as fever phobia. Research on fever phobia has predominantly focused on the role of fever misconceptions in triggering anxiety and impeding a proper fever management, in terms of both concept and operationalization, with little attention to the influence of the relationship between caregivers and the healthcare team. The aim of this pilot study was to explore and describe fever-related knowledge, experience and behaviour among a sample of caregivers, paediatricians and their medical assistants in the Canton of Ticino, Switzerland. We used a qualitative study design with semi-structured, one-to-one interviews with paediatricians employed in private healthcare facilities, their medical assistants and caregivers with at least one child between the ages of 0 and 3 years. We conducted individual interviews either in person or by phone, according to participants' preferences, between October 2020 and February 2021. We performed an inductive-deductive analysis of the transcripts to identify the most meaningful themes from participants' reports. The analysis of the transcripts yielded three main themes. The first theme refers to participants' awareness of the emotional component in managing the child's fever and the challenges this component presents. The second theme refers to the risk of overtreating when the child's right to be sick is not recognized and respected. The third theme refers to the importance of the relational component, showing how a solid therapeutic alliance with the healthcare team helps caregivers develop self-confidence in managing the child's fever. This study contributes to advance our understanding of fever phobia and to a better conceptualization and operationalization of this phenomenon. CONCLUSION: Our results point out to the importance of going beyond a knowledge gap paradigm and recognizing both the emotional and the relational component of fever phobia, the former being entrenched in latter, that is, the unique relationship caregivers establish with their child's paediatrician and the medical assistant. WHAT IS KNOWN: • Research on fever phobia has predominantly focused on the role of fever misconceptions in triggering anxiety and impeding a proper fever management, in terms of both concept and operationalization, with little attention to the relational component of this phenomenon. WHAT IS NEW: • Our results point out to the importance of recognizing the emotional component of fever phobia, beyond its declarative and procedural knowledge dimensions. They also suggest that overtreating is not necessarily and not only the result of a phobia but also of a particular conception of health and the relational component of this phenomenon, which is entrenched in the unique relationship caregivers establish with their child's paediatrician and the medical assistant.

RESUMO

AIM: Misconceptions and non-evidence-based practices toward childhood fever are reported worldwide. Medical students might be ideal candidates to introduce long-lasting changes in clinical practice. However, no study has gauged the effectiveness of an educational intervention to improve fever management in this population. We conducted an educational, interventional study on childhood fever among final-year medical students. METHODS: We conducted a prospective, multicentre interventional study employing a pre/post-test design. Participants from three Italian Universities filled in a questionnaire just before the intervention (T0), immediately after (T1) and 6 months later (T2) in 2022. The intervention was a two-hour lecture focused on the pathophysiology of fever, recommendations for its treatment and risks associated with improper management. RESULTS: 188 final-year medical students (median age of 26 years, 67% females) were enrolled. Relevant improvements in the criterion for treating fever and conceptions about the beneficial effects of fever were observed at T1 and T2. Similar data were found for the reduction of physical methods advice to decrease body temperature and concerns for brain damage from fever. CONCLUSION: This study shows for the first time that an educational intervention is effective in changing students' conceptions and attitudes toward fever both in the short and medium term.

RESUMO

BACKGROUND: Despite consensus about the importance of implementing shared decision-making (SDM) in clinical practice, this ideal is inconsistently enacted today. Evidence shows that SDM practices differ in the degree of involvement of patients or family members, or in the amount of medical information disclosed to patients in order to "share" meaningfully in treatment decisions. Little is known on which representations and moral justifications physicians hold when realizing SDM. This study explored physicians' experiences of SDM in the management of paediatric patients with prolonged disorders of consciousness (PDOC). Specifically, we focused on physicians' SDM approaches, representations, and ethical justifications for engaging in SDM. METHODS: We used a qualitative approach to explore the SDM experiences of 13 ICU physicians, paediatricians, and neurologists based in Switzerland who have been or were involved in the care of paediatric patients living with PDOC. A semi-structured interview format was used and interviews were audio-recorded and transcribed. Data were analysed through thematic analysis. RESULTS: We found that participants followed three main decision-making approaches: the "brakes" approach, characterized by maximized family's decisional freedom, though conditional to physician's judgment regarding the medical appropriateness of a treatment; the "orchestra director" approach, characterized by a multi-step decision-making process led by the main physician aimed at eliciting the voices of the care team members and of the family; and the "sunbeams" approach, characterized by a process oriented to reach consensus with family members through dialogue, where the virtues of the physician are key to guide the process. We also found that participants differed in the moral justifications sustaining each approach, citing the duty to respect parental autonomy, to invest in an ethics of care, and to employ physicians' virtues to guide the decision-making process. CONCLUSION: Our results show that physicians come to perform SDM in different ways, with several representations, and distinct ethical justifications. SDM training among health care providers should clarify the ductility of SDM and the several ethical motivations underpinning it, rather than insisting on the principle of respect for patient's autonomy as its only moral foundation.

RESUMO

BACKGROUND: Unfounded concerns regarding fever are increasingly observed among nurses worldwide. However, no study has so far explored the preferred approach towards pediatric fever among nursing students. Therefore, we aimed to investigate the attitude towards pediatric fever among final-year nursing students. METHODS: Between February and June 2022, final-year nursing students of 5 Italian university hospitals were asked to answer an online survey on their approach to fever in children. Both quantitative and qualitative methods were utilized. Multiple regression models were employed to explore the existence of moderators on fever conceptions. RESULTS: The survey was filled in by 121 nursing students (response rate 50%). Although most students (98%) do not consider discomfort to treat fever in children, only a minority would administer a second dose of the same antipyretic in nonresponsive cases (5.8%) or would alternate antipyretic drugs (13%). Most students would use physical methods to decrease fever (84%) and do not think that fever has mainly beneficial effects in children (72%). The own know-how adequacy on fever was inversely associated (OR 0.33, 95% CI 0.13-0.81) with the beliefs that high fever might lead to brain damage. No further predictive variable was significantly associated with the concern that fever might be associated with brain damage, the advice of physical methods use, and the assumption that fever has mostly positive effects. DISCUSSION: This study shows for the first time that misconceptions and inappropriate attitudes towards fever in children are common among final-year nursing students. Nursing students could potentially be ideal candidates for improving fever management within clinical practice and amongst caregivers.

RESUMO

BACKGROUND AND PURPOSE: Advances in medicine have resulted in treatments that can extend the survival of patients with prolonged disorders of consciousness (PDOC) for several years. However, several diagnostic and prognostic uncertainties remain, particularly in the care of pediatric patients. In the absence of international guidelines, we aimed to explore physicians' decision-making when managing pediatric patients with PDOC. METHODS: We conducted a qualitative study using semistructured, individual interviews and employed an inductive thematic analytical approach to explore physicians' subjective experiences and decision-making when managing pediatric patients with PDOC. We recruited a purposive sample of 19 Italian-speaking physicians currently or previously employed in intensive care units or pediatric, internal medicine, or neurology departments in Switzerland. RESULTS: Participants stated that making clinical decisions involving pediatric patients with PDOC is extremely challenging, because the decisional process requires finding a balance between several contending factors. We found that physicians experienced ambivalence in three domains of care (time, goals of care, and target of care), and that they were aware of the risk of self-fulfilling prophecies for both prognosis and main clinical outcomes. CONCLUSIONS: Our study confirmed that experienced clinicians acknowledge the complex nature and challenge of clinical decision-making in the care of pediatric patients with PDOC. More research is warranted to improve and expand existing guidelines aimed at assisting and facilitating clinical and ethical decision-making, and improving physicians' awareness of the factors affecting their decisions when dealing with patients with PDOC.

RESUMO

BACKGROUND: Increasing public awareness and understanding of dementia is the second key action area of the 2017 WHO Global action plan on a public health response to dementia. To achieve this aim, the first indispensable step is to understand the average level of dementia knowledge and to identify areas of low dementia knowledge. We aimed to quantify dementia knowledge in the general population, and to explore the extent to which it differs by age, sex, education, and indirect experience with dementia. METHODS: We conducted an online cross-sectional survey in two Italian-speaking sites, south Switzerland (Ticino) and northern Italy (Piedmont). The survey was distributed between September and December 2019. We registered socio-demographic characteristics including whether the participant had contact with a person living with dementia, and measured dementia knowledge with the Dementia Knowledge Assessment Survey (DKAS). RESULTS: Misconceptions about dementia were common among respondents, and lack of knowledge has been identified in dementia causes, characteristics, risk factors, and health promotion. Our results point out the lack of knowledge about how to communicate and relate with, and take care of a person living with dementia. The overall DKAS score was significantly and positively associated with female sex (ß = 0.21; p < 0.001), educational level (ß = 0.15; p < 0.001) and contact with a person living with dementia (ß = 0.17; p < 0.001), but not with age (ß = -0.01; p = 0.57). CONCLUSION: Our results confirmed that general population's knowledge of dementia is thin. Interventional studies that rely on participatory action research methods are warranted to co-design interventions aimed at improving dementia knowledge and understanding in the public.

RESUMO

BACKGROUND: Receiving a diagnosis that leads to severe disability in childhood can cause a traumatic experience with long-lasting emotional stress for patients and family members. In recent decades, emerging digital technologies have transformed how patients or caregivers of persons with disabilities manage their health conditions. As a result, information (eg, on treatment and resources) has become widely available to patients and their families. Parents and other caregivers can use digital platforms such as websites or social media to derive social support, usually from other patients and caregivers who share their lived experiences, challenges, and successes on these platforms. However, gaps remain in our understanding of platforms that are most frequently used or preferred among parents and caregivers of children with disabilities. In particular, it is not clear what factors primarily drive or discourage engagement with these digital tools and what the main ethical considerations are in relation to these tools. OBJECTIVE: We aimed to (1) identify prominent digital platforms used by parents or caregivers of children with disabilities; (2) explore the theoretical contexts and reasons for digital platform use, as well as the experiences made with using these platforms reported in the included studies; and (3) identify any privacy and ethical concerns emerging in the available literature in relation to the use of these platforms. METHODS: We conducted a scoping review of 5 academic databases of English-language articles published within the last 10 years for diseases with childhood onset disability and self-help or parent/caregiver-led digital platforms. RESULTS: We identified 17 papers in which digital platforms used by parents of affected children predominantly included social media elements but also search engines, health-related apps, and medical websites. Information retrieval and social support were the main reasons for their utilization. Nearly all studies were exploratory and applied either quantitative, qualitative, or mixed methods. The main ethical concerns for digital platform users included hampered access due to language barriers, privacy issues, and perceived suboptimal advice (eg, due to missing empathy of medical professionals). Older and non-college-educated individuals and ethnic minorities appeared less likely to access information online. CONCLUSIONS: This review showed that limited scientifically sound knowledge exists on digital platform use and needs in the context of disabling conditions in children, as the evidence consists mostly of exploratory studies. We could highlight that affected families seek information and support from digital platforms, as health care systems seem to be insufficient for satisfying knowledge and support needs through traditional channels.

RESUMO

OBJECTIVES: To explore prospective participants' preferences regarding the return of their individual-specific results from a dementia prevalence study (a probabilistic diagnosis of dementia). METHODS/DESIGN: We conducted a qualitative study with 22 individuals aged 45 to 86 and resident in the Canton of Ticino (Switzerland). Participants had previously joined the validation phase of an epidemiological study into dementia and its impact. RESULTS: We found that individuals welcome the return of their individual-specific results, provided these meet a number of validity, clinical, and personal utility criteria. They justify researchers' duty to return study findings with the principles of beneficence (eg, providing information that can help participants' medical decision-making) and justice (eg, acknowledging participants' efforts to help research by sharing their personal information). Furthermore, individuals anticipate societal benefits of the return of individual specific study findings, including improved interpersonal relationships among individuals and decreased dementia-related stigma. CONCLUSIONS: Our findings suggest that researchers should address the return of individual-specific study results early on during study design and involve prospective participants in identifying both the conditions under which results should be offered and the perceived individual and societal benefits returning can have.

RESUMO

Health literacy is an important predictor of health status, health behaviours, and other health outcomes. However, research on health literacy in the Arab world is scarce and no health literacy tool has been validated to test the health literacy level of the Lebanese population so far. The aim of this study was to validate Arabic translations of three commonly used health literacy assessment tools, the S-TOFHLA, the REALM-R, and the Brief Health Literacy Screening items. The tools were linguistically and culturally adapted to the Lebanese context, and 250 face-to-face interviews were conducted in an outpatient clinic in Beirut, Lebanon, between April and June 2015. The General Self-Efficacy Scale and socio-demographic questions such as gender, age, origin, education and chronic condition were included to assess predictive validity. Reliability of the instruments was found to be low to high (Cronbach's α =0 .94 for the S-TOFHLA, Cronbach's α = 0.46 for the REALM-R). Younger and highly educated participants scored higher on the S-TOFHLA. The Brief Health Literacy Screening items were significantly correlated with age, education, self-efficacy and the S-TOFHLA, reinforcing the convergent and predictive validity of the two tools. Results indicate that the S-TOFHLA and the three screening questions are a valuable tool to measure health literacy in Lebanon and, allowing for minimal adaptations according to each country's healthcare system, in the entire Arabic-speaking area.

RESUMO

BACKGROUND: Whether or not to vaccinate one's child is one of the first health-related decisions parents have to make after their child's birth. For the past 20 years, the share of parents choosing not to immunize their children has increased in many countries, for various reasons. Among these, rumors affirming that vaccinations contain dangerous chemicals or might trigger severe chronic diseases have negatively affected parental attitudes towards pediatric immunizations, particularly the vaccination against measles, mumps and rubella (MMR), raising a number of public health concerns. The primary aim of this qualitative study is to understand what drives parents' decision, giving special attention to vaccination literacy and psychological empowerment in such a context. METHODS: Twenty individual semi-structured interviews were conducted in the Canton of Ticino (Switzerland) between January and June 2014. Participants were either mothers or fathers of children less than 1 year old living in Switzerland. An inductive thematic analysis was performed to identify the main themes with regard to vaccination literacy and psychological empowerment in the MMR vaccination decision-making. RESULTS: Parents' reports yielded four main themes: (a) the paradox of the free choice, referring to the misinterpretation of current vaccination policies; (b) giving up the power, pointing at the outcomes of a low perceived competence; (c) a far-reaching decision, reflecting the importance attributed to the MMR choice and the different levels of impact the decision can have; (d) the demand for shared-decision making, referring to the parental needs in relation to the child's healthcare provider. CONCLUSION: Understanding what drives parents' management of their children's immunization schedule in terms of vaccination literacy and psychological empowerment can help health professionals to communicate more effectively with parents in order to facilitate an informed decision, and stakeholders to design tailored health education programs and materials. This can ultimately help increase the coverage of the MMR vaccination.

RESUMO

Despite cardiopulmonary resuscitation (CPR) and do-not-attempt-resuscitation (DNAR) decisions are increasingly considered an essential component of hospital practice and patient inclusion in these conversations an ethical imperative in most cases, there is evidence that such discussions between physicians and patients/surrogate decision-makers (the person or people providing direction in decision making if a person is unable to make decisions about personal health care, e.g., family members or friends) are often inadequate, excessively delayed, or absent. We conducted a study to qualitatively explore physician-reported CPR/DNAR decision-making approaches and CPR/DNAR conversations with patients hospitalized in the internal medicine wards of the four main hospitals in Ticino, Southern Switzerland. We conducted four focus groups with 19 resident and staff physicians employed in the internal medicine unit of the four public hospitals in Ticino. Questions aimed to elicit participants' specific experiences in deciding on and discussing CPR/DNAR with patients and their families, the stakeholders (ideally) involved in the discussion, and their responsibilities. We found that participants experienced two main tensions. On the one side, CPR/DNAR decisions were dominated by the belief that patient involvement is often pointless, even though participants favored a shared decision-making approach. On the other, despite aiming at a non-manipulative conversation, participants were aware that most CPR/DNAR conversations are characterized by a nudging communicative approach where the physician gently pushes patients towards his/her recommendation. Participants identified structural cause to the previous two tensions that go beyond the patient-physician relationship. CPR/DNAR decisions are examples of best interests assessments at the end of life. Such assessments represent value judgments that cannot be validly ascertained without patient input. CPR/DNAR conversations should be regarded as complex interventions that need to be thoroughly and regularly taught, in a manner similar to technical interventions.

RESUMO

The emergence of big data science presents a unique opportunity to improve public-health research practices. Because working with big data is inherently complex, big data research must be clear and transparent to avoid reproducibility issues and positively impact population health. Timely implementation of solution-focused approaches is critical as new data sources and methods take root in public-health research, including urban public health and digital epidemiology. This commentary highlights methodological and analytic approaches that can reduce research waste and improve the reproducibility and replicability of big data research in public health. The recommendations described in this commentary, including a focus on practices, publication norms, and education, are neither exhaustive nor unique to big data, but, nonetheless, implementing them can broadly improve public-health research. Clearly defined and openly shared guidelines will not only improve the quality of current research practices but also initiate change at multiple levels: the individual level, the institutional level, and the international level.

RESUMO

Massive coral bleaching episodes induced by thermal stress are one of the first causes of coral death worldwide. Overproduction of reactive oxygen species (ROS) has been identified as one of the potential causes of symbiosis breakdown between polyps and algae in corals during extreme heat wave events. Here, we propose a new strategy for mitigating heat effects by delivering underwater an antioxidant to the corals. We fabricated zein/polyvinylpyrrolidone (PVP)-based biocomposite films laden with the strong and natural antioxidant curcumin as an advanced coral bleaching remediation tool. Biocomposites' mechanical, water contact angle (WCA), swelling, and release properties can be tuned thanks to different supramolecular rearrangements that occur by varying the zein/PVP weight ratio. Following immersion in seawater, the biocomposites became soft hydrogels that did not affect the coral's health in the short (24 h) and long periods (15 days). Laboratory bleaching experiments at 29 and 33 °C showed that coral colonies of Stylophora pistillata coated with the biocomposites had ameliorated conditions in terms of morphological aspects, chlorophyll content, and enzymatic activity compared to untreated colonies and did not bleach. Finally, biochemical oxygen demand (BOD) confirmed the full biodegradability of the biocomposites, showing a low potential environmental impact in the case of open-field application. These insights may pave the way for new frontiers in mitigating extreme coral bleaching events by combining natural antioxidants and biocomposites.

RESUMO

Receiving the diagnosis of a severe disease may present a traumatic event for patients and their families. To cope with the related challenges, digital interventions can be combined with traditional psychological support to help meet respective needs. We aimed to 1) discuss the most common consequences and challenges for resilience in Neuro Muscular Disease patients and family members and 2) elicit practical needs, concerns, and opportunities for digital platform use. We draw from findings of a transdisciplinary workshop and conference with participants ranging from the fields of clinical practice to patient representatives. Reported consequences of the severe diseases were related to psychosocial challenges, living in the nexus between physical development and disease progression, social exclusion, care-related challenges, structural and financial challenges, and non-inclusive urban design. Practical needs and concerns regarding digital platform use included social and professional support through these platforms, credibility and trust in online information, and concerns about privacy and informed consent. Furthermore, the need for safe, reliable, and expert-guided information on digital platforms and psychosocial and relationship-based digital interventions was expressed. There is a need to focus on a family-centered approach in digital health and social care and a further need in researching the suitability of digital platforms to promote resilience in the affected population. Our results can also inform city councils regarding investments in inclusive urban design allowing for disability affected groups to enjoy a better quality of life.

RESUMO

OBJECTIVES: The COVID-19 pandemic continues, and evidence on infection- and vaccine-induced immunity is key. We assessed COVID-19 immunity and the neutralizing antibody response to virus variants across age groups in the Swiss population. STUDY DESIGN: We conducted a cohort study in representative community-dwelling residents aged five years or older in southern Switzerland (total population 353,343), and we collected blood samples in July 2020 (in adults only, N = 646), November-December 2020 (N = 1457), and June-July 2021 (N = 885). METHODS: We used a previously validated Luminex assay to measure antibodies targeting the spike (S) and the nucleocapsid (N) proteins of the virus and a high-throughput cell-free neutralization assay optimized for multiple spike protein variants. We calculated seroprevalence with a Bayesian logistic regression model accounting for the population's sociodemographic structure and the test performance, and we compared the neutralizing activity between vaccinated and convalescent participants across virus variants. RESULTS: The overall seroprevalence was 7.8% (95% CI: 5.4-10.4) by July 2020 and 20.2% (16.4-24.4) by December 2020. By July 2021, the overall seroprevalence increased substantially to 72.5% (69.1-76.4), with the highest estimates of 95.6% (92.8-97.8) among older adults, who developed up to 10.3 more antibodies via vaccination than after infection compared to 3.7 times more in adults. The neutralizing activity was significantly higher for vaccine-induced than infection-induced antibodies for all virus variants (all p values < 0.037). CONCLUSIONS: Vaccination chiefly contributed to the reduction in immunonaive individuals, particularly those in older age groups. Our findings on the greater neutralizing activity of vaccine-induced antibodies than infection-induced antibodies are greatly informative for future vaccination campaigns.

Objectives: We compared socio-demographic characteristics, health-related variables, vaccination-related beliefs and attitudes, vaccination acceptance, and personality traits of individuals who vaccinated against COVID-19 and who did not vaccinate by December 2021. Methods: This cross-sectional study used data of 10,642 adult participants from the Corona Immunitas eCohort, an age-stratified random sample of the population of several cantons in Switzerland. We used multivariable logistic regression models to explore associations of vaccination status with socio-demographic, health, and behavioral factors. Results: Non-vaccinated individuals represented 12.4% of the sample. Compared to vaccinated individuals, non-vaccinated individuals were more likely to be younger, healthier, employed, have lower income, not worried about their health, have previously tested positive for SARS-CoV-2 infection, express lower vaccination acceptance, and/or report higher conscientiousness. Among non-vaccinated individuals, 19.9% and 21.3% had low confidence in the safety and effectiveness of SARS-CoV-2 vaccine, respectively. However, 29.1% and 26.7% of individuals with concerns about vaccine effectiveness and side effects at baseline, respectively vaccinated during the study period. Conclusion: In addition to known socio-demographic and health-related factors, non-vaccination was associated with concerns regarding vaccine safety and effectiveness.

RESUMO

This study aimed to understand parental discourse about vaccination, and to provide guidance for communication that addresses the needs of parents. We analyzed parental discourse on child vaccination in general and tick-borne encephalitis (TBE) specifically in a Swiss parental online community. For this purpose, a data set containing 105k posts written by parents between 2007 and 2019 was analyzed using a combination of linguistic discourse analysis and qualitative content analysis. Results show that parents enter into a multidimensional decision-making process, characterized by elaborate practices of negotiation, consideration of vaccination recommendations as well as six distinct influencing thematic factors (vaccination safety, development and control, effectiveness, epidemiology, necessity, alternatives or additional prevention methods). The study shows a clear pattern of seasonality, with parents talking about TBE vaccination mostly triggered by events such as tick bites in spring and summer. From a public health perspective, the study emphasizes the need for sufficient, balanced, and tailored information about TBE vaccination. Online forums provide valuable information about what matters to parents and when, which can help public health authorities and practitioners provide information according to these concerns and enhance health literacy among parents.
