Leveraging public health nurses for disaster risk communication in Fukushima City: a qualitative analysis of nurses' written records of parenting counseling and peer discussions

Predicting Public Cooperation with Face Covering at the Early Phases of COVID-19: Building Public Trust, Confidence, Knowledge Through Governmental Two-Way Symmetrical Communication

Despite the agreement on the importance of two-way communication during governmental response to pandemics, few studies provided empirical evidence to support the effectiveness of such communication strategy in times of a public health crisis. Integrating the concept of two-way symmetrical communication and the Trust, Confidence, and Cooperation model (the TCC model), this study investigates how strategic communication practices, in particular two-way symmetrical communication, is related to public's perceived trust and confidence in governments (i.e., CDC in this study), and how these perceptions may affect decisions to comply with the preventive behaviors (i.e., face covering in this study), while taking the moderating role of knowledge into consideration. An online survey was conducted with 502 participants who were living in the United States in early April 2020. The findings showed that two-way symmetrical communication may increase public trust and confidence in governments, and improve individuals' knowledge about the pandemic, which all subsequently leads to compliance with recommended behaviors. The results contribute to the theoretical understanding of pandemic communication and provide implications for practitioners in pandemic management, suggesting that health institutions should adopt two-way symmetrical communication practices in respond to public health emergencies.

The Background of a Patient Undergoing Long-Term Periodontal Disease Maintenance Using Step for Coding and Theorization: A Case Report

Periodontal maintenance is crucial for long-term periodontal stability, but some patients do not undertake maintenance following their initial treatment. To date, the motivations, backgrounds, and concerns of patients who underwent maintenance have not been researched. Therefore, we analyzed the subject's intentions and the behavior of the patient affected by periodontal maintenance using Step for Coding and Theorization (SCAT). The subject was a 50-year-old woman diagnosed with periodontitis. Periodontal therapy included oral hygiene instruction, scaling, root planing, and periodontal surgery. She has been continuing maintenance for 21 years. An interview was conducted on a one-to-one basis, between the patient and the surgeon, using a semistructured interview. The contents of the interview included her reasons for visiting the university hospital and her reasons for continuing maintenance. For the qualitative analysis using SCAT, the vocabulary obtained from the interview was filled out in a SCAT form. We determined that the relationship between the dental personnel and the patient was good, and we could convey the importance of maintenance to the patient. Appropriate periodontal treatment and the maintenance of a good relationship with the dental health oral care provider are key factors in improving the rate of maintenance visits and ensuring long-term periodontal stability.

Key issues in Japan's public health centers to prepare for future pandemics: a text mining study using a topic model

BACKGROUND

In Japan, over 450 public health centers played a central role in the operation of the local public health system in response to the COVID-19 pandemic. This study aimed to identify key issues for improving the system for public health centers for future pandemics.

METHODS

We conducted a cross-sectional study using an online questionnaire. The respondents were first line workers in public health centers or local governments during the pandemic. We solicited open-ended responses concerning improvements needed for future pandemics. Issues were identified from these descriptions using morphological analysis and a topic model with KHcoder3.0. The number of topics was estimated using Perplexity as a measure, and Latent Dirichlet Allocation for meaning identification.

RESULTS

We received open-ended responses from 784 (48.6%) of the 1,612 survey respondents, which included 111 physicians, 330 nurses, and 172 administrative staff. Morphological analysis processed these descriptions into 36,632 words. The topic model summarized them into eight issues: 1) establishment of a crisis management system, 2) division of functions among public health centers, prefectures, and medical institutions, 3) clear role distribution in public health center staff, 4) training of specialists, 5) information sharing system (information about infectious diseases and government policies), 6) response to excessive workload (support from other local governments, cooperation within public health centers, and outsourcing), 7) streamlining operations, and 8) balance with regular duties.

CONCLUSIONS

This study identified key issues that need to be addressed to prepare Japan's public health centers for future pandemics. These findings are vital for discussions aimed at strengthening the public health system based on experiences from the COVID-19 pandemic.

Impacts of environmental decontamination on the rebuilding of returnees' lives after the Fukushima accident

Environmental decontamination after a nuclear disaster not only contributes to reducing the public's exposure to radiation, it also introduces waste disposal issues arising from the decontamination process. In addition to that issue, the optimisation of decontamination efforts necessitates the consideration of various environmental, economic, and societal factors. Stakeholders' perspectives are important for identifying the multifaceted aspects to be considered. We conducted a semi-structured interview survey in 2019 with ten residents in a rural community in Fukushima, Japan, which experienced a six-year-long evacuation due to the 2011 Fukushima Daiichi Nuclear Power Plant accident. The main survey questions addressed returnees' perceptions of the decontamination of farmlands and forests. The 'Steps for Coding and Theorization' procedure was used for qualitative analysis. The analysis illuminated the positive and negative impacts of the decontamination process on the rebuilding of the returnees' rural lives from various perspectives and identified elements to be considered for the optimisation of future remediation efforts. The removal of radioactive materials had a positive psychological impact on the returnees, fostering a sense of security that their crops were safe and instilling confidence that the high-quality environment of the region had been restored. These aspects were not included among the initial governmental objectives for decontamination, which were aimed solely at reducing radiation exposure. By contrast, the removal of fertile topsoil from farmland had a negative impact on the residents, making them hesitant to resume farming. Our findings suggest that emphasising procedural fairness in decision-making of decontamination options such as reflection of stakeholders' opinions led to residents perceiving their post-decontamination situation more positively. Our results provide valuable insights for optimising remediation strategies for the recovery process following a significant nuclear accident.

Between Policy and Risk Communication: Coverage of Air Pollution in Ghanaian Newspapers

Mass media plays an increasingly persuasive role in orienting political decisions, shaping social agendas, influencing individuals' actions, and interpreting scientific evidence for the public. With growing scientific understanding of the health, social and environmental consequences of air pollution, there is an urgent need to understand how media coverage frames these links, particularly in Low- and Middle-Income Countries. This paper examines how the Ghanaian print and electronic media houses are covering air pollution issues given increased efforts at reducing air pollution within the country. The main goal of this work is to track the progress of policies to reduce air pollution. We used a qualitative content analysis of selected newspapers (both traditional and online) between the periods 2016 and 2021 and we found that articles on air pollution have been increasing, with more reportage on impact and policy issues compared to causes of air pollution. A focus group with six members of the media confirmed an interest in covering health and environmental issues, particularly coverage of specific diseases and human-interest pieces. This increasing attention is likely associated with intensifying local, national, and international action to improve air quality in Ghana, and growing awareness of the health impacts of air pollution.

Concerns related to returning home to a “difficult-to-return zone” after a long-term evacuation due to Fukushima Nuclear Power Plant Accident: A qualitative study

This study aimed to identify concerns related to returning to the Nagadoro district of Iitate Village, Fukushima Prefecture, Japan, in 2023 among its residents as it is designated as a difficult-to-return zone after the Fukushima Daiichi nuclear power plant accident. The following four concerns were extracted from the interviews and qualitative analysis: “Difficulties in restarting/continuing farming,” which represent the difficulties in making a living from agriculture due to the absence of family members and neighbors, and the insufficient radiation decontamination; “Discriminatory treatment of products and residents from villagers,” which suggests the presence of discriminations that residents of Nagadoro district are eccentrics and its agricultural products should not be treated together with those of other districts in the Village due to the recognition that the district is severely polluted by radiation; “Shift of the responsibility of returning home from the country to residents by scapegoating,” which is characterized by the shift of responsibility from the government to the residents, including harsh social criticism of the residents of Nagadoro district for not returning even though the evacuation order has been lifted, when it should have been the government’s responsibility to recover the district to a habitable state; “Loss of options for continued evacuation,” which is the loss or weakening of the position of residents of the Nagadoro district who continue to evacuate, and of administrative compensation, resulting from the legal change that they are no longer “evacuees” after the evacuation order is lifted. The findings of this study will provide a foundation for the support of residents of the Nagadoro district after lifting the evacuation order scheduled for the spring of 2023. The findings may be transferable to the residents of other difficult-to-return zones expected to be lifted after the Nagadoro district and to also a radiation disaster-affected place in the future.

Students' perception of a hybrid interprofessional education course in a clinical diabetes setting: a qualitative study

OBJECTIVES

To explore what the student participants learned and how they felt about the use of three educational settings, namely, face-to-face workshop setting, asynchronous and synchronous online learning environments and interactions with outpatients in a real-world clinical setting in a hybrid interprofessional education course.

METHODS

This qualitative study used semi-structured in-depth interviews with healthcare undergraduate student participants in a course comprising workshops in three educational settings. A total of 15 healthcare undergraduate students, which included four medical, three pharmacy, five nursing and three nutrition students, completed this IPE course. All students agreed to participate in the study. We conducted four focus groups selected using convenient sampling. Focus group transcripts were analysed using the 'Steps for Coding and Theorization' qualitative data analysis method. We investigated the students' perception through the experience of three educational settings in the hybrid interprofessional education course.

RESULTS

The students recognised that this course had three types of educational spaces, namely, real, semi-real and unreal. Then, the positive changes in the awareness of students are trained in recognition of the patient perspective, the recognition of the roles discharged by the other professions and the recognition of the functions of their own profession after experiencing the educational spaces designated for this course.

CONCLUSIONS

The repeated experience of participants to real, semi-real and unreal educational spaces promoted changes over time in the students' awareness of interprofessional competencies with respect to patient-centred care and ameliorated their readiness to undertake interprofessional tasks.

Physical Therapists' Perception and Educational Opportunities to Improve Exercise Adherence in Older Patients and Clients: A Qualitative Study

Objectives

: The aim of the study was to understand the physical therapist's experience and perception of the support they give to their older patients or clients to continue exercising.

Methods

: Using purposive sampling, we recruited fifteen physical therapists with more than 5 years of clinical experience and conducted semi-structured interviews. We analyzed the transcribed data using thematic analysis.

Results

: Three main themes emerged: (1) the expected results as healthcare professionals, (2) clinical experience and continuing professional development, and (3) limited educational opportunities. Physical therapists struggled to achieve a certain level of exercise adherence in their patients, and the low success rate decreased their confidence. We found that physical therapists needed not only to rely on clinical experience but also to integrate scientific evidence to implement better behavioral change techniques; they would also appreciate receiving appropriate educational opportunities.

Conclusions

: This study revealed a possibility of educational insufficiency for physical therapist to support of behavior change to improve exercise adherence in the older population.

Analysis of the Training Effect of a Nursing Undergraduate Course on the Management of Radiation-Related Health Concerns-A Single Group Experiment

After the 2011 Fukushima Daiichi accident, demands regarding nursing staff's management of nuclear disasters have increased. This study aimed to evaluate a basic training program to teach undergraduate nursing students on how to deal with public anxiety following a nuclear disaster. We analyzed the data of 111 third-year nursing students attending a Japanese university. We set attainment goals in three domains (cognitive, affective, psychomotor) regarding their acquisition of consultation techniques for radiation-related health concerns. We compared pre- and post-class response scores on a knowledge test and calculated word frequencies in health consultation scenarios. The pre-class mean score was 12.2 out of 27 points and the post-class mean score (directly after the course) was 21.0, a significant increase (p < 0.001). The mean level of attainment in each of the three domains increased significantly from pre-test to post-test (p < 0.001). The variety and number of words in the health consultations also increased. Students attained the program goals for radiation-related health concerns in all domains. During disasters, there is a great need for nursing staff to administer physical and mental care to the public. This program was evaluated to be one wherein nursing staff can acquire fundamental knowledge about radiation in a short time.

An Analysis of Government Communication in the United States During the COVID-19 Pandemic: Recommendations for Effective Government Health Risk Communication

Governments throughout the world can learn many critical lessons from examining instances of ineffective communication with the public during the global coronavirus disease (COVID‐19) pandemic. Ineffective government communication has resulted in a great deal of public confusion and misunderstanding, as well as serious errors in responding to this evolving health threat, leading to disastrous health and social outcomes for the public and prolonging the pandemic, especially within the United States. This article uses systems theory as a template for analyzing government communication in the United States during the COVID‐19 pandemic, providing governments with recommendations for establishing effective health risk communication strategies for use with the public. The communication strategies offered here promote the delivery of relevant, accurate, and sensitive information to key public groups, minimizing communication noise to guide desirable coordinated actions. These communication strategies can be applied locally, nationally, and internationally.

An experiential approach to developing radiological content for public health nursing: Lessons from a nuclear disaster

OBJECTIVE

This study identified the radiological content required for PHNs and public health nursing students based on PHNs' experiences caring for people affected by the 2011 Fukushima Daiichi nuclear power plant accident.

DESIGN

We used qualitative research, interviews, and content analysis.

SAMPLE

Participants were eight PHNs employed by local governments in Fukushima and neighboring prefectures.

RESULTS

Six content themes regarding the nuclear disaster were identified: (a) basic knowledge about radiation, (b) public health nursing activities in emergency exposure situations, (c) management in emergency exposure situations, (d) consultation to support residents affected by the nuclear disaster, (e) activities in the existing exposure situations, and (f) disaster preparedness in the planned exposure situations. Necessary content shifted depending on the phase of the nuclear disaster recovery.

CONCLUSIONS

The use of the experiences of PHNs after the nuclear power plant accident to inform PHNs and public health nursing students will enable PHNs to respond appropriately and support people without difficulties. Comprehensive radiation content is needed to address the range of situations caused by nuclear disaster.

Qualitative analysis of the vocabulary used in work logs of a preventive programme for elderly oral function and nutrition

BACKGROUND

In Japan, day care services for elders include programmes aimed at improving nutrition and oral and motor functions. Few studies have qualitatively assessed these interventions.

OBJECTIVE

To qualitatively search for the characteristic words used in the work logs of a preventive programme on oral function and nutrition for elders by intervention period and intervention type． METHODS: We included 83 participants (81.3 ± 8.2 years) from four day care services in Japan and divided them into the following groups randomly: those who received oral function intervention only, nutritional intervention only and those who received combined oral function plus nutritional intervention. The interventions were conducted twice per month for 24 months. Data from handwritten work logs were entered into a computer as text files. Monitoring of frequently appearing words, co-occurrence analysis and cross-tabulation by intervention period and intervention types was conducted using text mining analysis.

RESULTS

Correspondence analysis revealed that the words used during 1-6 months and 7-12 months were similar in participants' subjective content, and those used in objective content in 13-18 months and 19-24 months were similar. These results indicate that subjective improvements increased after 13 months, and it was maintained within 24 months. The combined intervention type is ideal for oral and nutrition problems.

CONCLUSION

Because this text mining approach revealed the changes in the words used and could be used to monitor any subjective improvement, this approach may help evaluate the effects of preventive care.

Newspaper coverage before and after the HPV vaccination crisis began in Japan: a text mining analysis

Background

The human papillomavirus (HPV) vaccination coverage rate has fallen sharply in Japan since 2013, when newspapers began covering negative campaigns against the vaccination. We examined and compared contents from newspaper articles before and after the start of this HPV vaccination crisis.

Methods

We collected articles published between January 2005 and September 2017 in the four daily national Japanese newspapers with the highest domestic circulation. We then conducted text mining analysis to chronologically examine content distribution.

Results

From among the 1178 articles analyzed, 12 types of contents were identified. Contents related to cervical cancer prevention, such as on the risk of developing cervical cancer, causes of cervical cancer, and the effects of vaccination, were frequently conveyed until 2012. However, after March 2013, they were replaced with anti-vaccination contents, such as on adverse effects to vaccines, alleged victims, and related lawsuits. Meanwhile pro-vaccination contents, such as safety statements from the World Health Organization, scarcely received coverage.

Conclusions

Newspaper contents changed profoundly before and after the start of the vaccination crisis. Those newspaper reports potentially had impact on readers’ beliefs and actions. Journalists should strive for impartial coverage so readers can make more-informed decisions. Health professionals should be expected to work with journalists to help improve impartiality in newspaper coverage. The Ministry of Health, Labour and Welfare should discus benefits and risks of the HPV vaccination based on the scientific evidences, and consider to resume the proactive recommendation of HPV vaccination. Well-organized advocacy among medical societies, scientists and health professionals will also be needed to influence the government.

Japanese anti- versus pro-influenza vaccination websites: a text-mining analysis

Anti-vaccination sentiment exists worldwide and Japan is no exception. Health professionals publish pro-influenza vaccination messages online to encourage proactive seeking of influenza vaccination. However, influenza vaccine coverage among the Japanese population is less than optimal. The contents of pro- and anti-influenza vaccination websites may contribute to readers' acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing content on websites for and against influenza vaccination. We conducted online searches in January 2017 using two major Japanese search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as 'pro', 'anti' or 'neutral' depending on their claims, with author(s) classified as 'health professionals', 'mass media' or 'laypersons'. Text-mining analysis was conducted, and statistical analysis was performed using a chi-squared test. Of the 334 websites analyzed, 13 content topics were identified. The three most frequently appearing content topics on pro-vaccination websites were vaccination effect for preventing serious cases of influenza, side effects of vaccination, and efficacy rate of vaccination. The three most frequent topics on anti-vaccination websites were ineffectiveness of influenza vaccination, toxicity of vaccination, and side effects of vaccination. The main disseminators of each topic, by author classification, were also revealed. We discuss possible tactics of online influenza vaccination promotion to counter anti-vaccination websites.

Cancer information needs according to cancer type: A content analysis of data from Japan's largest cancer information website

The provision of information about cancer is an important aspect of cancer care. Cancer information provided online is expected to meet the needs of information seekers. Whether information needs vary according to tumor site is largely unknown. We aimed to examine similarities and differences in informational needs by cancer type. Data were collected using a questionnaire administered on Japan's largest cancer information website, “Ganjoho service”. A total of 2782 free descriptive responses in the period from April 2012 to December 2017 were analyzed using text-mining software. We identified the top 10 informational need contents, in order of appearance frequency, for eight tumor sites: gastric, colorectal, esophageal, lung, pancreatic, breast, cervical, and prostate cancer. Frequent information needs common to all tumor sites included symptoms, disease stages, treatments, chance of cure, recovery, metastasis, and recurrence. A need for information about diet, pain, side effects of treatments, complementary and alternative medicine was frequent for some tumor sites. Tumor site-specific information should include the following, according to cancer type: information of scirrhous carcinoma for gastric cancer; unusual feces for colorectal cancer; lung X-ray images for lung cancer; early detection for pancreatic cancer; adenocarcinoma, sexual activity, pregnancy, and childbirth for cervical cancer; breast conservation or reconstruction and triple negative cancer for breast cancer; test values and diagnosis and urinary problems for prostate cancer; and hormone therapy for breast and prostate cancer. Cancer information provided online should meet these frequent informational needs, considering similarities and differences of the information required according to tumor site.

•

We examined similarities and differences in cancer information needs by tumor site.

•

Common needs are symptoms, stages, treatment, cure, recovery, metastasis, recurrence.

•

Site-specific needs include diet, pain, side effects, early detection, test values.

•

Cancer information should be provided to meet frequent needs, by tumor site.

Listen to the outpatient: qualitative explanatory study on medical students' recognition of outpatients' narratives in combined ambulatory clerkship and peer role-play

BACKGROUND

Understanding patients' narratives has been associated with methods of improving care that go beyond what may be regarded as a "narrow" view of scientific medicine. Medical interview training in which medical students develop understanding of the importance of patients' narratives is receiving increased attention. However, students generally receive education on patients' narratives that does not distinguish inpatients and outpatients. No studies exploring the characteristics of outpatients' narratives have been reported. We developed an educational program combining ambulatory clerkship and peer role-play using actual narratives from outpatients that students had encountered during their clerkship. These narratives were used as peer role-play scenarios in which the students acted as outpatients. This study explored what and how medical students learned about the characteristics of outpatients' narratives through this original educational program.

METHODS

Participants were 70 fifth-year medical students from Nagoya University, Japan. We conducted 13 focus groups, based on a convenience sample of 11 groups in 2012, one group in 2013, and one group in 2017 (from 17 clinical groups in each year). Focus group transcripts were analyzed using the "Steps for Coding and Theorization" qualitative data analysis method. We assessed medical anthropological findings regarding narratives in a conceptual framework.

RESULTS

Patients' narratives as perceived by medical students were divided into four quadrants by two axes: medical versus lived content, and objective versus subjective structure. Students recognized that outpatients' narratives mainly used a subjective structure, but were mixed and crossed each quadrant. This was described as "irreproducibility." Students also recognized that narratives of simulated patients and inpatients were mainly limited to a medical-lived content with an objective structure. These differences in narrative characteristics were recognized through students' previous interactions with simulated patients and inpatients.

CONCLUSIONS

Despite some limitations, medical students learn about patients' narratives in our original educational program in a way that would be difficult to achieve through training using simulated patients or inpatients.

Twitter use in scientific communication revealed by visualization of information spreading by influencers within half a year after the Fukushima Daiichi nuclear power plant accident

Scientific communication through social media, particularly Twitter has been gaining importance in recent years. As such, it is critical to understand how information is transmitted and dispersed through outlets such as Twitter, particularly in emergency situations where there is an urgent need to relay scientific information. The purpose of this study is to examine how original tweets and retweets on Twitter were used to diffuse radiation related information after the Fukushima Daiichi nuclear power plant accident. Out of the Twitter database, we purchased all tweets (including replies) and retweets related to Fukushima Daiichi nuclear power plant accident and or radiation sent from March 2^nd, 2011 to September 15^th, 2011. This time frame represents the first six months after the East Japan earthquake, which occurred on March 11^th, 2011. Using the obtained data, we examined the number of tweets and retweets and found that only a small number of Twitter users were the source of the original posts that were retweeted during the study period. We have termed these specific accounts as “influencers”. We identified the top 100 influencers and classified the contents of their tweets into 3 groups by analyzing the document vectors of the text. Then, we examined the number of retweets for each of the 3 groups of influencers, and created a retweet network diagram to assess how the contents of their tweets were being spread. The keyword “radiation” was mentioned in over 24 million tweets and retweets during the study period. Retweets accounted for roughly half (49.7%) of this number, and the top 2% of Twitter accounts defined as “influencers” were the source of the original posts that accounted for 80.3% of the total retweets. The majority of the top 100 influencers had individual Twitter accounts bearing real names. While retweets were intensively diffused within a fixed population, especially within the same groups with similar document vectors, a group of influencers accounted for the majority of retweets one month after the disaster, and the share of each group did not change even after proven scientific information became more available.

Lexical analysis suggests differences between subgroups in anxieties over radiation exposure in Fukushima

Although many experts have attempted communication about radiation risk, fears about radiation exposure stemming from the Fukushima Daiichi Nuclear Power Plant accident remain deeply rooted. The characteristics of the anxiety vary with social background, which makes it difficult to alleviate with one approach. Our ultimate goal is therefore to create risk-communication materials tailored to various groups with differing social backgrounds. Towards that end, the purpose of the present study was to clarify potential factors associated with radiation-related anxieties within these groups. After obtaining informed consent, we conducted focus group interviews (FGIs) with Fukushima residents from various social groups, including evacuees, emergency responders, government personnel, medical staff, and decontamination workers. We obtained narrative comments specifically related to the following two themes: (i) lessons learned (at work or home) in light of one's position in society, and (ii) health issues. After transcribing the comments, we examined potential factors associated with radiation-related anxieties using both quantitative and qualitative study methods simultaneously, using the KH Coder software and the Steps for Coding and Theorization (SCAT) method respectively. FGIs were undertaken with 141 persons. Categories, words and storylines extracted in this study might indicate potential anxieties that are unique to each group, but our analysis also suggested that some anxieties were common to all groups. We expect to continue the analyses and, ultimately, to establish group-tailored risk-communication materials for achieving our final goal of adapting and better managing risk-communication efforts to help people deal more effectively with the scientific, technological and societal changes that came about after the disaster.

Mental health of nurses after the Fukushima complex disaster: a narrative review

Work-related mental health impairment is recognized as a real problem in the context of helping responders, including health professionals, due to adverse health outcomes after a severe disaster. The Great East-Japan Earthquake, which occurred on 11 March 2011, was an unprecedented complex disaster that caused a nuclear accident at the Fukushima Daiichi Nuclear Power Plant (NPP). In addition to disaster stress and daily work, medical and health-care professionals, particularly nurses, provided counseling services to residents concerned about radiation health risks or mental health issues. This review focuses on the psychological aspects of the complex nuclear disaster, which was a combined artificial nuclear accident and natural disaster, and we investigated the psychological effects on hospital nurses associated with their experiences during the disaster. We looked at several investigations into the mental health of nurses after a nuclear disaster and in other situations. It was shown that mental health of nurses is impacted, not only after nuclear disasters but also in other circumstances. Furthermore, we noted the effects of extended periods of a heavy workload and daily life. Regarding anxiety about radiation exposure, nurses who had more knowledge of radiation tended to have better mental health, suggesting that education about the health risks of radiation exposure is important for health-care professionals. In summary, it is essential that nurses are provided with education about radiation exposure and its associated health risks, and also that there is a comprehensive approach to mental health care for nurses during the chronic phase of a disaster.

Contents of Japanese pro- and anti-HPV vaccination websites: A text mining analysis

OBJECTIVE

In Japan, the human papillomavirus (HPV) vaccination rate has sharply fallen to nearly 0% due to sensational media reports of adverse events. Online anti-HPV-vaccination activists often warn readers of the vaccine's dangers. Here, we aimed to examine frequently appearing contents on pro- and anti-HPV vaccination websites.

METHODS

We conducted online searches via two major search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as "pro," "anti," or "neutral" according to their claims, with the author(s) classified as "health professionals," "mass media," or "laypersons." We then conducted a text mining analysis.

RESULTS

Of the 270 sites analyzed, 16 contents were identified. The most frequently appearing contents on pro websites were vaccine side effects, preventable effect of vaccination, and cause of cervical cancer. The most frequently appearing contents on anti websites were vaccine side effects, vaccine toxicity, and girls who suffer from vaccine side effects. Main disseminators of each content according to the author's expertise were also revealed.

CONCLUSION

Pro-HPV vaccination websites should supplement deficient contents and respond to frequent contents on anti-HPV websites.

PRACTICE IMPLICATIONS

Effective tactics are needed to better communicate susceptibility to cervical cancer, frequency of side effects, and responses to vaccine toxicity and conspiracy theories.

Collaborative Processes of Developing A Health Literacy Toolkit: A Case from Fukushima after the Nuclear Accident

Following the Fukushima nuclear accident in 2011, the central government provided health and radiation-related information that was incomplete, difficult to understand and contradictory, leading to widespread distrust in the community. Thus, from 2013 to 2014, we developed and implemented a series of health literacy training workshops for local public health nurses, often the first health care professionals with whom members of the community interact. The results from our program evaluation revealed that the task of paraphrasing professional terms and skills related to relaying numeric information to the community were difficult for the nurses to acquire. In 2016, to further support the communication efforts of public health nurses, we developed a pocket-size "health literacy toolkit" that contained a glossary explaining radiation-related terms in plain language and an index to measure the accessibility of both text and numerical information, so that nurses could calibrate and appreciate the literacy demand of information. This case study documents an interprofessional collaborative effort for the development of the toolkit, and highlights the iterative process of building health literacy skills in health care professionals.

Japanese citizens' attitude toward end-of-life care and advance directives: A qualitative study for members of medical cooperatives

Background

Japanese citizens are interested in choosing their own end‐of‐life care, but few have created their own advance directive. This study examined changes among Japanese citizens' attitudes toward end‐of‐life care and advance directives and explored factors that affected these attitudes.

Methods

We conducted five focus groups with 48 participants in 2009 and 2010. All participants were members of health cooperatives in Tokyo.

Results

We identified many barriers and reasons for creating and writing down advance directives. Experience caring for dying people and having a serious disease affected attitudes toward advance directives. Some participants changed their attitude toward end‐of‐life care by writing their own advance directive.

Conclusions

When someone is writing advance directives, asking about his/her past experience of caring may be helpful. And learning about or filling out advance directives may help to break down resistance to using these documents.

Mental Health and Related Factors of Hospital Nurses

The mental health of hospital nurses is a key health issue in public health promotion during the recovery phase following the Fukushima disaster. In this study, conducted 4 years after the disaster, we analyzed the overall mental health, knowledge, risk perception of radiation, and work and daily life burdens of nurses working at medical institutions in the Fukushima Prefecture (collection rate = 89.6%; response number = 730). Overall mental health status was estimated using the 12-item version of the General Health Questionnaire, and 333 respondents (45.6%) scored above the 12-item General Health Questionnaire threshold point (≥4), indicating probable emotional distress compared with the general population under normal circumstances. Multivariate logistic analysis suggested that the ability to cope with daily life and work-related stressors were more important than risk perception and acquisition of knowledge regarding radiation and its control methods for supporting the mental health of nurses following the Fukushima disaster.

Assertions of Japanese Websites for and Against Cancer Screening: a Text Mining Analysis

Background: Cancer screening rates are lower in Japan than in Western countries such as the United States and the United Kingdom. While health professionals publish pro-cancer-screening messages online to encourage proactive seeking for screening, anti-screening activists use the same medium to warn readers against following guidelines. Contents of pro- and anti-cancer-screening sites may contribute to readers’ acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing contents on sites for and against cancer screening. Methods: We conducted online searches in December 2016 using two major search engines in Japan (Google Japan and Yahoo! Japan). Targeted websites were classified as “pro”, “anti”, or “neutral” depending on their claims, with the author(s) classified as “health professional”, “mass media”, or “layperson”. Text-mining analyses were conducted, and statistical analysis was performed using the chi-square test. Results: Of the 169 websites analyzed, the top-three most frequently appearing content topics in pro sites were reducing mortality via cancer screening, benefits of early detection, and recommendations for obtaining detailed examination. The top three most frequent in anti-sites were harm from radiation exposure, non-efficacy of cancer screening, and lack of necessity of early detection. Anti-sites also frequently referred to a well-known Japanese radiologist, Makoto Kondo, who rejects the standard forms of cancer care. Conclusion: Our findings should enable authors of pro-cancer-screening sites to write to counter misleading anti-cancer-screening messages and facilitate dissemination of accurate information.

Thinking, talking, and working with professional community workers after the Fukushima nuclear accident

This article examines postdisaster public health activities (focusing primarily on parenting support) through collaboration between universities and local government, and reports on the support provided to public health nurses, who are the gatekeepers of community health. For a year after the Fukushima disaster, discussions were held on the short- and long-term measures for responding to the concerns of parents, who face difficulty interpreting risks. Child health checkup data and mothers' counselling sessions with public health nurses were analysed to gather evidence to reinforce the health system over the long term. As the results of the analysis showed a need for the development of a system for communicating health information in ways that are accessible to residents, a health literacy training programme was developed and implemented for public health nurses in Fukushima Prefecture.

Availability of Japanese Government's supplemental texts on radiation reflecting the Fukushima Daiichi Nuclear Power Plant accident for elementary and secondary education from dental students' understanding

Following the Fukushima Nuclear Power Plant accident, the Japanese government created two supplemental texts about radiation reflecting the accident for elementary, middle school, and high school students. These texts were made to explain radiation and consequently to obtain public consent for the continuation of the nuclear program. The present study aimed to evaluate the appropriateness of the content of the texts and to collect the basic data on the level of understanding necessary to improve radiation education. Lectures on radiology including nuclear energy and the Fukushima accident were given to 44 fourth-year dental students in 2013. The questionnaire was administered in 2014 when these students were in their sixth-year. The survey was also administered to 40 first-year students and 41 fourth-year students who hadn't any radiology lectures. Students rated their level of understanding of 50 phrases used in the texts on a four-point scale (understanding = 3, a little knowledge = 2, having heard = 1, no knowledge = 0). Questions on taking an advanced physics course in high school and means of learning about radiation in daily life were also asked. The level of understanding of phrases in the supplemental text for middle and high school students was significantly higher among sixth-year students (mean = 1.43) than among first-year (mean = 1.12) or fourth-year (mean = 0.93) students (p < 0.05). Overall, the level of understanding was low, with scores indicating that most students knew only a little. First-year students learning about radiation from television but four-year and six-year students learning about radiation from newspaper scored significantly higher (p < 0.05). It was concluded that radiation education should be improved by using visual material and preparing educators to teach the material for improving the public's understanding of radiation use-especially nuclear power generation because the phrases used in the supplementary texts are very difficult for students to understand.

Mental health and psychological impacts from the 2011 Great East Japan Earthquake Disaster: a systematic literature review

Background

On March 11, 2011, Japan experienced an unprecedented combination of earthquake/tsunami/nuclear accidents (the Great East Japan Earthquake; GEJE). We sought to identify mental health and psychosocial consequences of this compound disaster.

Method

A systematic literature review was conducted of quantitative research articles addressing mental health of survivors and the psychological impact of the GEJE. For articles between March 2011 and December 2014, PubMed, PsychINFO, and EMBASE databases were searched with guidance on literature review method.

Results

Forty-nine studies met the inclusion criteria. A substantial proportion of the affected individuals experienced considerable psychological distress. Mental health outcomes included, but were not limited to, posttraumatic stress disorder, depression, and anxiety symptoms. Physical health changes, such as sleeping and eating disturbances, also occurred. In Fukushima, radioactive release induced massive fear and uncertainty in a large number of people, causing massive distress among the affected residents, especially among mothers of young children and nuclear plant workers. Stigma was additional challenge to the Fukushima residents. The review identified several groups with vulnerabilities, such as disaster workers, children, internally displaced people, patients with psychiatric disorders, and the bereaved.

Conclusions

Following the GEJE, a considerable proportion of the population was mentally affected to a significant degree. The affected individuals showed a wide array of mental and physical consequences. In Fukushima, the impact of nuclear disaster was immense and complex, leading to fear of radiation, safety issues, and stigma issues.

Health Literacy Training for Public Health Nurses in Fukushima: A Multi-site Program Evaluation

Public health nurses (PHNs) are community residents' access points to health information and services in Japan. After the Fukushima nuclear accident, they were challenged to communicate radiation-related health information to best meet community needs. We previously developed and evaluated the outcome of a single-site health literacy training program to augment PHNs' ability to improve community residents' access to written health information. This paper presents an evaluation of an identical training program using data combined from multiple sites, and further included proximal and distal evaluations to document the impact of health literacy training in a post-disaster setting. A total of 64 participants, primarily experienced PHNs, attended one of three multi-session health literacy workshops conducted in multiple sites across Fukushima. Quantitative and qualitative data on PHNs' training satisfaction, self-evaluation of achievements regarding training goals, and application of learned skills were collected and analyzed. Each workshop consisted of two 2-hour sessions introducing health literacy and assessment tools and developing skills to improve written materials, followed by a one-month follow-up assessment on PHNs' application of the gained skills in the field. Post-training evaluations on the appropriateness and usefulness of the workshop were highly positive. At the end of the one-month follow-up, 45% of participants had gained confidence in assessing and revising written materials and had applied the skills they had gained to develop and communicate health information in various settings and modes. This increase in confidence was associated with further application of the learned skills at the municipal level. However, participants reported difficulties in explaining risks, and the need to learn more about plain language to be able to paraphrase professional terms. This paper highlighs the positive outcomes of health literacy training among PHNs. Practical strategies to reinforce their skills to use plain language and communicate the epidemiological concept of risk are also recommended.

Nuclear disasters and health: lessons learned, challenges, and proposals

Past nuclear disasters, such as the atomic bombings in 1945 and major accidents at nuclear power plants, have highlighted similarities in potential public health effects of radiation in both circumstances, including health issues unrelated to radiation exposure. Although the rarity of nuclear disasters limits opportunities to undertake rigorous research of evidence-based interventions and strategies, identification of lessons learned and development of an effective plan to protect the public, minimise negative effects, and protect emergency workers from exposure to high-dose radiation is important. Additionally, research is needed to help decision makers to avoid premature deaths among patients already in hospitals and other vulnerable groups during evacuation. Since nuclear disasters can affect hundreds of thousands of people, a substantial number of people are at risk of physical and mental harm in each disaster. During the recovery period after a nuclear disaster, physicians might need to screen for psychological burdens and provide general physical and mental health care for many affected residents who might experience long-term displacement. Reliable communication of personalised risks has emerged as a challenge for health-care professionals beyond the need to explain radiation protection. To overcome difficulties of risk communication and provide decision aids to protect workers, vulnerable people, and residents after a nuclear disaster, physicians should receive training in nuclear disaster response. This training should include evidence-based interventions, support decisions to balance potential harms and benefits, and take account of scientific uncertainty in provision of community health care. An open and joint learning process is essential to prepare for, and minimise the effects of, future nuclear disasters.

Public health activities for mitigation of radiation exposures and risk communication challenges after the Fukushima nuclear accident

Herein we summarize the public health actions taken to mitigate exposure of the public to radiation after the Fukushima accident that occurred on 11 March 2011 in order to record valuable lessons learned for disaster preparedness. Evacuations from the radiation-affected areas and control of the distribution of various food products contributed to the reduction of external and internal radiation exposure resulting from the Fukushima incident. However, risk communication is also an important issue during the emergency response effort and subsequent phases of dealiing with a nuclear disaster. To assist with their healing process, sound, reliable scientific information should continue to be disseminated to the radiation-affected communities via two-way communication. We will describe the essential public health actions following a nuclear disaster for the early, intermediate and late phases that will be useful for radiological preparedness planning in response to other nuclear or radiological disasters.

Immediate effects of the Fukushima nuclear power plant disaster on depressive symptoms among mothers with infants: a prefectural-wide cross-sectional study from the Fukushima Health Management Survey

BACKGROUND

Mothers of young children are at high-risk for developing adverse mental health effects following a nuclear accident. Using the Japanese pregnancy registration system, the prefecture of Fukushima launched a population-based survey of women who were pregnant at the time of the Fukushima nuclear accident in order to assess their and their newborns' health. In this paper, we focus on the results of a screen for depressive symptoms among new mothers and its association with geographical region and interruption of obstetrical care after the Fukushima nuclear accident, which occurred after the Great East Japan Earthquake on March 11, 2011.

METHODS

The survey targeted women who lived in Fukushima prefecture and who had registered their pregnancies between August 1, 2010 and July 31, 2011. Among the 16,001 women targeted, 9,321 returned the questionnaires (response proportion = 58.3%) and data from 8,196 women with singleton live births were analyzed. The main outcome measure was a standard two-item depression screen. Regional radiation levels were determined from the prefecture's periodical reports, and interruption in obstetrical care after the Fukushima nuclear accident was determined from mothers' individual responses to the questionnaire.

RESULTS

Among the 8,196 women, 2,262 (28%) screened positive for depressive symptoms. After adjusting for maternal and infant characteristics, both mothers in Soso, the region in which the nuclear power plant is located, and mothers that had changed obstetrical care facilities were significantly more likely to screen positive for depression. In contrast, mothers in Iwaki and Aizu, regions with relatively low radiation levels, were significantly less likely to screen positive for depression.

CONCLUSIONS

Our findings suggest that improving mental health support for mothers with infants should be a high priority in the acute phase of nuclear disaster response. We further recommend that in the strategic provisioning of parental support, close attention should be paid to regional variations in negative mental health consequences, particularly to those who experienced an interruption in their obstetrical care.

Patient perspectives on online health information and communication with doctors: a qualitative study of patients 50 years old and over

Background

As health care systems around the world shift toward models that emphasize self-care management, there is increasing pressure for patients to obtain health information online. It is critical that patients are able to identify potential problems with using the Internet to diagnose and treat a health issue and that they feel comfortable communicating with their doctor about the health information they acquire from the Internet.

Objective

Our aim was to examine patient-identified (1) problems with using the Internet to identify and treat a health issue, (2) barriers to communication with a doctor about online health information seeking, and (3) facilitators of communication with a doctor about patient searches for health information on the Internet.

Methods

For this qualitative exploratory study, semistructured interviews were conducted with a sample of 56 adults age 50 years old and over. General concerns regarding use of the Internet to diagnose and treat a health issue were examined separately for participants based on whether they had ever discussed health information obtained through the Internet with a doctor. Discussions about barriers to and facilitators of communication about patient searches for health information on the Internet with a doctor were analyzed using thematic analysis.

Results

Six higher-level general concerns emerged: (1) limitations in own ability, (2) credibility/limitations of online information, (3) anxiety, (4) time consumption, (5) conflict, and (6) non-physical harm. The most prevalent concern raised by participants who communicated with a doctor about their online health information seeking related to the credibility or limitations in online information. Participants who had never communicated with a doctor about their online health information seeking most commonly reported concerns about non-physical harm. Four barriers to communication emerged: (1) concerns about embarrassment, (2) concerns that the doctor doesn’t want to hear about it, (3) belief that there is no need to bring it up, and (4) forgetting to bring it up. Facilitators of communication included: (1) having a family member present at doctor visits, (2) doctor-initiated inquiries, and (3) encountering an advertisement that suggested talking with a doctor.

Conclusions

Overall, participants displayed awareness of potential problems related to online health information seeking. Findings from this study point to a set of barriers as well as facilitators of communication about online health information seeking between patients and doctors. This study highlights the need for enhanced patient communication skills, eHealth literacy assessments that are accompanied by targeted resources pointing individuals to high-quality credible online health information, and the need to remind patients of the importance of consulting a medical professional when they use online health resources to diagnose and treat a health issue.

Chronological changes in Japanese physicians' attitude and behavior concerning relationships with pharmaceutical representatives: a qualitative study

Background

Recent qualitative studies indicated that physicians interact with pharmaceutical representatives depending on the relative weight of the benefits to the risks and are also influenced by a variety of experiences and circumstances. However, these studies do not provide enough information about if, when, how and why their attitudes and behaviors change over time.

Methods and Findings

A qualitative study using semi-structured face-to-face individual interviews was conducted on 9 Japanese physicians who attended a symposium on conflicts of interest held in Tokyo. Interviews were designed to explore chronological changes in individual physicians' attitude and behavior concerning relationships with pharmaceutical representatives and factors affecting such changes. Their early interaction with pharmaceutical representatives was passive as physicians were not explicitly aware of the meaning of such interaction. They began to think on their own about how to interact with pharmaceutical representatives as they progressed in their careers. Their attitude toward pharmaceutical representatives changed over time. Factors affecting attitudinal change included work environment (local regulations and job position), role models, views of patients and the public, acquisition of skills in information seeking and evidence-based medicine, and learning about the concepts of professionalism and conflict of interest. However, the change in attitude was not necessarily followed by behavioral change, apparently due to rationalization and conformity to social norms.

Conclusions

Physicians' attitudes toward relationships with pharmaceutical representatives changed over time and factors affecting such changes were various. Paying attention to these factors and creating new social norms may be both necessary to produce change in behavior consistent with change in attitude.

Health literacy training for public health nurses in fukushima: a case-study of program adaptation, implementation and evaluation

Health literacy comprises not only an individual's ability to gain access to, understand and use health information, but also health care providers' ability to make health information accessible and usable. The Fukushima nuclear accident has posed challenges related to the communication of radiation-related health information. Public health nurses are gatekeepers of community health in Japan, and have primary responsibility for communicating this complex information about science and risk to lay members of the community. A health literacy training program was designed to augment communication skills of participating nurses with two primary goals: changing communication practices and norms among public health nurses, and improving access to information for community residents. Training content incorporated an overview of health literacy skills (including numeracy), processes for assessing written materials and visual displays, as well as guidelines for text improvement. The workshop was spread across two days with two-hour sessions each day. A proximal post-training evaluation survey was conducted, followed by a more distal one-month follow-up evaluation to assess the application of learned skills in practice. Twenty-six nurses in Fukushima City attended the first trial. Post-training evaluations were highly positive, with agreement from 85-100% of participants on the appropriateness and usefulness of the workshop. During a one-month follow-up, the nurses reported applying new knowledge and skills to develop written materials. However, they faced difficulties sharing their new skills with colleagues and challenges changing work norms. Participants also encountered difficulties using graphics and explaining risks in practice. This paper highlights the importance of providing health literacy training opportunities for professionals to strengthen health system's ability to accessible information and services. This program also serves as important reference for future disaster management efforts.
