RESUMEN
BACKGROUND: The diversification of information sources and changes in social structures necessitates updates on the state of public awareness of palliative care. Therefore, we clarified the status and determinants of awareness, information sources, and beliefs, regarding palliative care in Japan. METHODS: This nationwide cross-sectional survey included 10 000 participants aged ≥20 years enrolled through random sampling using a two-stage stratification in 2023. We used a mailed self-administered questionnaire (INFORM Study 2023). The questionnaire items were selected (partially modified) from the Health Information National Trends Survey (USA) to ensure comparability, included palliative care awareness, information sources, and beliefs. Weighted logistic regression was conducted to explore the determinants of awareness. RESULTS: Of the 3452 participants that responded (response rate: 35.3%), 65.2% had palliative care awareness. The weighted logistic regression analysis revealed that respondents less likely to have any palliative care awareness were younger, were male, had limited education history, had lower household income, and were non-Internet users. Of these, sex had the clear association (adjusted odds ratio for female vs. male: 3.20 [95% CI: 2.66-3.85]). Across all age groups, healthcare professionals (58.5%) and the Internet (30.5%) were the most trusted source of information. Younger participants frequently received information online. Most participants believed that palliative care was beneficial, although 82.0% associated it with death. CONCLUSIONS: The Japanese population had a relatively high palliative care awareness, with the majority trusting information from healthcare professionals rather than the Internet. Further efforts are warranted to address barriers to receiving trustworthy palliative care information.
RESUMEN
INTRODUCTION: Older patients with cancer are less likely to express their treatment preferences than younger patients. Question prompt lists (QPLs) facilitate communication between patients and physicians. Geriatric assessment (GA) is recommended when older patients with cancer make treatment decisions. This study estimated the effect size of a shared decision-making (SDM) support program combining QPLs with GA in terms of patients' subjective evaluation of the SDM process for a future definitive randomized controlled trial. We also evaluated the number and quality of aging-related communication during consultations, and feasibility and acceptability of the study for exploratory purposes. MATERIALS AND METHODS: This is a pilot study with randomized allocation and blind evaluation. Patients aged 65 years or older at the National Cancer Center Hospital, Tokyo, Japan, scheduled to discuss the changes of their treatment, were randomly assigned in a 1:1 ratio to the SDM support program or usual care. This program consisted of 30-60 min of face-to-face coaching, with QPLs and GA provided before the coaching. As the primary endpoint, the decisional conflict scores given by the patients immediately after the consultation were compared between the two groups. For the secondary endpoints, the number and quality of aging-related communications during the consultations were assessed by evaluators (blinded) using audio-recordings. Adherence, burden, and usefulness were assessed for evaluating feasibility and acceptability of the SDM support program. RESULTS: Forty patients were enrolled. All patients completed the GA questionnaire, for which 70% did not require any individual assistance. Answering the questionnaires took approximately 11 min. The decisional conflict scores were mean [standard deviation (SD)]: 19.3 [10.8] vs. 18.0 [11.1] (effect size: Cohen's d = 0.12) for the SDM support program and usual care groups, respectively. The number of aging-related communications during the consultation for the new treatment was higher in the SDM support program group than the usual care (mean [SD]: 3.3 [1.2] vs. 2.2 [1.5], effect size: cohen's d = 1.32). Patients felt that the SDM support program was useful but not burdensome or difficult. DISCUSSION: The SDM support program was considered useful and feasible for older patients and able to facilitate communication regarding aging-related concerns. TRIAL REGISTRATION NUMBER: The study protocol was registered on September 23, 2020, in the UMIN Clinical Trials Registry (UMIN000041867).

OBJECTIVE: To describe patients' perceptions of the patient-centeredness of their communication with healthcare providers in Japan, and to examine factors associated with these perceptions. METHODS: We analyzed the cross-sectional data from the INFORM Study 2020, which is a nationwide survey on health information access in Japan. A total of 3605 respondents completed the survey. Our primary outcome was the nine elements of the patient-centered communication scale (PCCS), which was compiled from 2703 respondents (75.0%) reporting at least one provider visit within 12 months. It was rated on a four-point Likert scale: always, usually, sometimes, and never. We used binary logistic regression to examine the association between sociodemographic and health-related variables, and each element of the PCCS. RESULTS: For all elements, the percentage of respondents who agreed that their healthcare providers always communicated in a patient-centered way was low (17-31%). Patients with higher age, higher education, poorer general health status and a larger number of visits to providers in the previous 12 months were more likely to have positive perception. CONCLUSION: Patient-centered communication as reported in a national sample in Japan was low. CLINICAL IMPLICATIONS: Efforts are needed to improve the patient-centeredness of patient-provider communication in Japan to optimize health outcomes.

BACKGROUND: People with schizophrenia have a lower colorectal screening rate than the general population. A previous study reported an intervention using case management to encourage colorectal cancer screening for patients with schizophrenia in psychiatric outpatient settings. In this feasibility study, we developed provider-level implementation strategies and evaluated the feasibility of conducting a definitive trial in terms of the penetration of the intervention assessed at the patient level. Additionally, we examined the fidelity of strategies to implement the intervention at the provider level in a routine clinical psychiatric setting. METHODS: This was a multicenter, single-arm feasibility study with medical staff at psychiatric hospitals in Japan. The provider-level implementation strategies developed in this study included three key elements (organizing an implementation team appointed by the facility director, interactive assistance using a clear guide that outlines who in the hospital should do what, and developing accessible educational materials) to overcome major barriers to implementation of the intervention and four additional elements (progress monitoring, joint meetings and information sharing among participating sites, adaptation of encouragement methods to specific contexts, and education of on-site staff), with reference to the elements identified in the Expert Recommendations for Implementing Change (ERIC). The feasibility of the strategies was evaluated by the proportion of patients who were eligible for encouragement (patients with schizophrenia aged 40, 50, or 60) who received encouragement. We set the goal of providing encouragement to at least 40% of eligible patients at each site. RESULTS: Two public and four private psychiatric hospitals in Okayama and Shimane prefectures participated in this study. Regarding fidelity, all elements of the strategies were conducted as planned. Following the procedures in the guide, each team prepared and provided encouragement according to their own facility and region. Penetration, defined as the proportion of eligible patients who received encouragement, ranged from 33.3 to 100%; five of the six facilities achieved the target proportion. CONCLUSIONS: The provider-level implementation strategies to implement encouragement were feasible in terms of penetration of the intervention assessed at the patient level. The results support the feasibility of proceeding with a future definitive trial of these strategies. TRIAL REGISTRATION: jRCT, jRCT1060220026 . Registered on 06/04/2022.
RESUMEN
IntroductionIn Japan, heated tobacco products (HTPs) are promoted by the tobacco industry as reduced-risk tobacco products despite the lack of evidence for this claim. This study determined the distribution of HTP-harmfulness perception and identify the explanatory factors associated with the perception of HTP as less harmful than conventional cigarettes.MethodsA nationwide cross-sectional survey was conducted with Japanese people aged 20 years or older (INFORM Study 2020) using a self-administered questionnaire. We performed descriptive analysis and weighted logistic regression analysis to examine the relationship between explanatory factors (e.g., individual characteristics, socioeconomic status, and trusted sources of cancer information) and the perception of HTPs as less harmful.ResultsAmong 3,420 participants (response rate: 35.2%), the proportions of those who perceived HTPs as less harmful were 40.3% and 18.3% for users and non-users of tobacco, respectively. For participants aged 20-39 years, the proportion were 49.9% and 30.4%, respectively. Among 1,160 non-tobacco users who were familiar with HTPs, male, aged under 39 years, and had lower education were associated with the perception of HTPs as less harmful. Trusted sources of cancer information were not associated with the perception of HTPs as less harmful.ConclusionsThis study showed that, among non-tobacco users, being male, aged under 39 years, and lower education were associated with a perception of HTPs as less harmful. Public health stakeholders should provide the latest evidence about HTP harmfulness in their daily practice, and strengthen the regulations on HTP marketing directed at both tobacco- and non-tobacco users.
RESUMEN
Trust is a major factor in effective public dissemination and use of relevant health information to guide important health decisions. To examine mass media as a communication channel for delivering cancer information among Japanese adults, we identified the level of trust in various types of mass media as sources of cancer information, and examined factors associated with trust, including exposure to mass media, sociodemographic factors, and cancer history. Data were analyzed for 3,109 Japanese adults who responded to a nationally representative cross-sectional mail survey. Data included trust in cancer information sources, sociodemographic variables, cancer history, and exposure to mass media. Logistic regression analysis was used. The prevalence of high trust in cancer information sources was highest for physicians (94.7%). Among mass media, Internet (47.2%) was the most trusted source of cancer-related information, followed by television (44.3%), newspapers/magazines (42.7%), and radio (32.7%). The high-exposure group for newspapers (AOR = 1.28, 95%CI = 1.07-1.54) was more likely to trust newspapers. Similarly, high-exposure groups for radio (1.22, 1.02-1.45), Internet (1.21, 1.01-1.45), and television (1.30, 1.10-1.53) were positively associated with trust in each media type. Although trust in mass media was lower than trust in physicians, the study found that a large group of respondents had high levels of trust in mass media sources. Trust in cancer information from each mass media type was mainly related to the level of exposure to each mass media type. Developing health communication strategies using mass media may be effective for disseminating relevant cancer information in Japan.

INTRODUCTION: Since May 2019, comprehensive genomic profiling (CGP) has been covered by Japan's health insurance system for patients with solid tumours that have progressed on standard chemotherapy, rare tumours or tumours of unknown primary origin. Although CGP has the potential to identify actionable mutations that can guide the selection of genomically matched therapies for patients with advanced cancer and limited treatment options, less than 10% of patients benefit from CGP testing, which may have a negative impact on patients' mental status. The aim of this study is to investigate the prevalence of psychological distress and associated factors among patients with advanced cancer who are undergoing CGP testing across Japan. METHODS AND ANALYSIS: This multicentre, prospective cohort study will enrol a total of 700 patients with advanced cancer undergoing CGP testing. Participants will be asked to complete questionnaires at three timepoints: at the time of consenting to CGP testing (T1), at the time of receiving the CGP results (T2; 2-3 months after T1) and 4-5 months after T2 (T3). Primary outcome is the prevalence of depression as measured by the Patient Health Questionnaire-9 at the three timepoints. Secondary outcomes are the prevalence of anxiety and Quality of Life Score. Associated factors with psychological distress will also be examined, including knowledge about CGP, attitudes, values and preferences towards CGP, satisfaction with oncologists' communication and patient characteristics as well as medical information including CGP test results and genomically matched therapies if provided. The prevalence of depression and anxiety will be estimated using the unadjusted raw rates observed in the total sample. Longitudinal changes in measures will be explored by calculating differences between the timepoints. Multivariate associations between variables will be examined using multiple or logistic regression analysis depending on the outcomes to adjust for confounders and to identify outcome predictors. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Board of the National Cancer Center Japan on 5 January 2023 (ID: 2022-228). Study findings will be disseminated through peer-reviewed journals and conference presentations. TRIAL STATUS: The study is currently recruiting participants and the enrolment period will end on 31 March 2025, with an expected follow-up date of 31 March 2026. TRIAL REGISTRATION NUMBER: UMIN000049964.

The Japanese government's 2013 suspension of its proactive recommendation for Human papillomavirus (HPV) vaccination resulted in low HPV vaccination coverage and was unique. However, data on awareness and knowledge of HPV vaccines in the general population was limited. Here, to investigate more recent awareness and knowledge of HPV vaccines by age, gender, and socioeconomic status, we used data from the INFORM Study 2020, a nationally representative cross-sectional survey of self-administered questionnaires with 1,998 Japanese individuals aged 20 to 59 years. We found that 47.5% of females and 21.0% of males had heard of HPV, and 33.6% of females and 16.8% of males had knowledge of HPV vaccine efficacy. After adjusting for potential confounders, females aged 50-54 years were more likely to be aware of HPV than females aged 20-24 (AOR, 2.02, 95%CI: 1.12-3.65). Females (AOR, 2.13, 95%CI: 1.48-3.07) and males (AOR, 1.64, 95%CI: 1.03-2.59) with higher education had more awareness than those with less education. Females with higher education had more knowledge about HPV vaccine efficacy than those with less education (AOR, 1.70; 95%CI: 1.16-2.50). We found a generally low level of awareness and knowledge about HPV vaccines in Japan, which might be attributable to the suspension of proactive recommendations. Additionally, we identified disparities in awareness and knowledge by age, gender, socioeconomic status, and health literacy. Enhancing HPV awareness and understanding of HPV vaccines and implementing targeted efforts for specific subpopulations within Japan after the resumption of proactive recommendation for HPV vaccines, are imperative.

BACKGROUND: This study aimed to explore prefecture-level differences in suicide risk among patients with cancer in Japan. METHODS: Data from the National Cancer Registry, which covers the entire Japanese population, were used. Patients diagnosed with cancer between 2016 and 2017 were included. The standardized mortality ratio (SMR) for suicide within 2 years after cancer diagnosis was quantified compared with the general population for each prefecture. Multivariate Poisson regression analysis was conducted to quantify the adjusted relative risk using Hokkaido as the reference. RESULTS: The analysis included 2,133,502 patients. The SMRs were high among patients with cancer residing in certain prefectures, such as the Hokuriku region (the middle and western parts of Japan's main island). These areas also exhibited a significant relative risk in the Poisson regression model. CONCLUSION: The results demonstrated that patients with cancer in certain prefectures in Japan have a high suicide risk.

INTRODUCTION: Various guidelines recommend geriatric assessment (GA) for older adults with cancer, but it is not widely implemented in daily practice. This study uses an implementation framework to comprehensively and systematically identify multi-level barriers and facilitators to implementing GA in daily oncology practice. MATERIALS AND METHODS: We conducted 16 semi-structured interviews with healthcare providers in 10 designated cancer hospitals in Japan, using purposive and convenience sampling. The Consolidated Framework for Implementation Research (CFIR) was used to guide collection and analysis of interview data following a deductive content analysis approach with consensual qualitative research methods. After coding the interview data, ratings were assigned to each CFIR construct for each case, reflecting the valence and strength of each construct relative to implementation success. Then, those constructs that appeared to distinguish between high-implementation hospitals (HI) where GA is routinely performed in daily practice and low-implementation hospitals (LI) where GA is performed only for research purposes or not at all were explored. RESULTS: Of the 24 CFIR constructs assessed in the interviews, 15 strongly distinguished between HI and LI. In HI, GA was self-administered (Adaptability), or administered via a mobile app with interpretation (Design Quality and Packaging). In HI, healthcare providers were strongly aware of the urgent need to change practice for older adults (Tension for Change) and recognized that GA was compatible with existing workflow as part of their jobs (Compatibility), whereas in LI, they did not realize the need to change practice, and dismissed GA as an extra burden on their heavy workload. In HI, usefulness of GA was widely recognized by healthcare providers (Knowledge & Beliefs about the Intervention), GA had a high priority (Relative Priority) and had strong support from hospital directors, managers, and nursing chiefs (Leadership Engagement), and multiple stakeholders were successfully engaged, including nurses (Key Stakeholders), peer doctors (Opinion Leaders), and those who drive implementation of GA (Champions). DISCUSSION: These findings suggest that successful implementation of GA should focus on not only individual beliefs about the usefulness of GA and the complexity of GA itself, but also organizational factors related to hospitals and the engagement of multiple stakeholders.

Financial toxicity during cancer survival has been studied mainly in the United States; 47-49% of cancer survivors reported financial hardships and 12-63% reported debt owing to treatment costs. Financial toxicity is influenced by each country's economic status and healthcare system. We aimed to review the evidence on financial toxicity in Japan. A systematic search was performed using PubMed and Ichushi databases. We included English or Japanese peer-reviewed articles that (1) explored the experiences of cancer patients facing financial toxicity due to cancer diagnosis and treatment, (2) were specific to Japan, and (3) focused on the experiences of financial toxicities among cancer patients. Data were extracted focusing on the experiences of patients, families, and healthcare providers. The main themes were synthesized based on a previous study. The search yielded 632 citations from PubMed and 21 from Ichushi, and non-duplicates were identified. Of these, 31 articles were selected for full-text review. Literature was divided into studies describing the following elements: (a) risk factors for financial toxicity, (b) description of financial toxicity, (c) psychological reactions, (d) coping strategies for financial toxicity, and (e) impact on treatment outcomes. Only three studies reported comprehensive financial toxicity scores. Furthermore, treatment costs influenced physicians' treatment decisions, and patients and their families adopted various strategies to cope with treatment costs. Two studies showed that low current income and younger age were high-risk factors. As for utilization of the support system, approximately 70% of the patients used the high-cost medical expense system, 20% used the sickness benefit system, and 40% used the medical expense deduction system. Many cancer patients in Japan suffer from financial toxicity during cancer survival. One reason for this is that the awareness of the system supporting financial toxicity is insufficient and actual utilization is low. It is necessary to actively encourage patients to ask healthcare providers questions, improve the link between patients and the support system, reconstruct the support system design, and improve the method of publicizing the system.
RESUMEN
OBJECTIVES: This study aimed to validate the Japanese versions of the Trust in Oncologist Scale (TiOS-J) and the TiOS-Short Form (TiOS-SF-J). METHODS: A cross-sectional web-based survey was conducted among cancer patients in Japan. The forward-backward translation method was used to develop the TiOS-J. The web-based survey was mailed to 633 people, of whom 309 responded. After 2 weeks, 103 among the 156 first-time respondents completed the second survey to verify the reliability of the retest method. The validity was evaluated by exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Spearman's correlation coefficients between the Patient Satisfaction Questionnaire-Japanese, willingness to recommend the oncologist, trust in health care, and number of oncological consultations. To evaluate reliability, Cronbach's α and test-retest correlation were calculated. RESULTS: The theoretically driven four-factor model and the EFA-driven one-factor model of the full-form TiOS-J (18 items) did not result in an acceptable fit; however, CFA supported the one-dimensionality of the 5 items from the TiOS-SF-J (χ2 (5) = 12.36, p = 0.03, goodness-of-fit index = 0.984, adjusted goodness-of-fit index = 0.952, comparative fit index = 0.991, and root mean square error of approximation = 0.069). With regard to the reliability of TiOS-J and TiOS-SF-J, the Cronbach's alpha values were 0.94 and 0.89, respectively; the test-retest values were 0.82 and 0.78. SIGNIFICANCE OF RESULTS: This study indicated that the TiOS-J and TiOS-SF-J are valid and reliable instruments for measuring patients' trust in their oncologists and can be used to assess trust in oncologists for both clinical and research purposes.
RESUMEN
Objective: To develop the Japanese version of the Patient Satisfaction Questionnaire (PSQ-J) and examine its validity and reliability. Methods: A cross-sectional, web-based survey was conducted among cancer patients in Japan. The PSQ-J was developed following the forward-backward translation method, using a numerical rating scale. Data on patient characteristics and psychometric scales, like the PSQ-J, willingness to recommend an oncologist to others, trust in the healthcare system, uncertainty, and the Physician Compassion Questionnaire were collected. Validity was examined using exploratory and confirmatory factor analyses and by calculating the correlations between the total PSQ-J score and the criterion variables. Reliability was confirmed by Cronbach's alpha and test-retest score correlations at a two-week interval. Results: The first and second surveys were conducted on 309 and 107 patients, respectively. One-dimensionality and model fit were verified using factor analyses. The PSQ-J was significantly associated with other comparable scales. Cronbach's alpha was 0.962; the correlation between the PSQ-J test-retest scores was 0.835 (p < .001). Conclusion: The current study indicates that the PSQ-J can be valid and reliable for assessing satisfaction with oncologist consultation. Innovation: The PSQ-J enables the effective assessment of patient satisfaction with oncologist consultations, leading to better practice reflecting the patient's viewpoint.
RESUMEN
BACKGROUND: Tobacco control should be a higher public health priority in Japan. Some workplaces provide smoking cessation support and connect employees to effective smoking cessation treatments such as outpatient clinics. However, tobacco control measures have not been sufficiently implemented in Japan, especially in small- and medium-sized enterprises (SMEs), where resources are limited. Organizational commitment and consistent leadership are crucial to facilitate implementation, but research on whether supporting organizational leaders leads to health behavior changes among employees is limited. METHODS: This hybrid type II cluster randomized effectiveness implementation trial (eSMART-TC) aims to examine the effects of interactive assistance for SME management on health and implementation outcomes. We will provide interactive assistance to employers and health managers for 6 months, aiming to promote the utilization of reimbursed smoking cessation treatments by public health insurance and to implement smoke-free workplaces. The intervention will consist of three strategies: supporting employees through campaigns, tailored ongoing facilitation, and ensuring executive engagement and support. The primary health and implementation outcomes will be salivary cotinine-validated 7-day point-prevalence abstinence rate, and the adoption of two recommended measures (promoting utilization of smoking cessation treatment and implementing smoke-free workplaces) 6 months after the initial session, respectively. Other outcomes for implementation (e.g., penetration of smoking cessation clinic visits), health (e.g., salivary cotinine-validated 7-day point-prevalence abstinence rate at 12 months), and process (e.g., adherence and potential moderating factors) will be collected via questionnaires, interviews, logbooks, and interventionists' notes at 6 and 12 months. An economic analysis will be undertaken to assess the cost-effectiveness of the implementation interventions at 12 months. DISCUSSION: This will be the first cluster randomized controlled trial to evaluate the effectiveness of an implementation intervention with interactive assistance for employers and health managers in SMEs on smoking cessation and implementation of evidence-based tobacco control measures in SMEs. The findings of this trial targeting management in SMEs have the potential to accelerate the implementation of evidence-based smoking cessation methods as well as abstinence rates among employees in SMEs across Japan. TRIAL REGISTRATION: The study protocol has been registered in the UMIN Clinical Trials Registry (UMIN-CTR; ID: UMIN000044526). Registered on 06/14/2021.
RESUMEN
Precision medicine is rapidly changing the diagnostic and treatment spectrum of oncology. In May 2019, comprehensive genomic profiling (CGP) (somatic and/or germline) was approved for reimbursement in Japan. While the promise of novel and targeted therapies has elevated hopes for the benefits of CGP, the lack of relevant genomic findings and/or limited access to relevant therapies remain important themes in this field. These challenges may also negatively influence the psychology of both cancer patients and their family members. However, few studies have reported longitudinal data on quality of life (QOL) with CGP. Here, we report the protocol of a prospective study, Q-CAT (QOL for Cancer genomics and Advanced Therapeutics among patients and their family members), which aims to explore the mental burden on patients and families arising from the implementation of CGP testing by collecting real-world longitudinal data using outcomes obtained with an electronic patient report, known as ePRO. This study has been registered with the Japan Registry of Clinical Trials (jRCT1030200039).

BACKGROUND: Health literacy (HL) has gained increasing attention as a factor related to health behaviors and outcomes. This study aimed to investigate geographic differences in HL levels and effect modification by geographic area on their relationship with self-rated health in the Japanese population using a nationwide sample. METHODS: Data for this study were derived from a nationally representative cross-sectional survey on health information access for consumers in Japan using a mailed self-administered questionnaire in 2020 (INFORM Study 2020). Valid responses from 3,511 survey participants, selected using two-stage stratified random sampling, were analyzed in this study. HL was measured using the Communicative and Critical Health Literacy Scale (CCHL). Multiple regression and logistic regression analyses were conducted to examine the associations between geographic characteristics and HL and effect modification on the association between HL and self-rated health by geographic area, controlling for sociodemographic characteristics. RESULTS: The mean HL score was 3.45 (SD = 0.78), somewhat lower compared with previous studies on the Japanese general population. HL was higher in Kanto area than in Chubu area, after controlling for sociodemographic factors and municipality size. Furthermore, HL was positively associated with self-rated health after controlling for sociodemographic and geographic factors; however, this association was more evident in eastern areas than in western areas. CONCLUSION: The findings indicate geographic differences in HL levels and effect modification by geographic area on the relationship between HL and self-rated health in the general Japanese population. HL was more strongly associated with self-rated health in eastern areas than in western areas. Further investigation is needed to explore the moderating effects of areal features, including the distribution of primary care physicians and social capital, when formulating strategies to improve HL in different contexts.

OBJECTIVES: To reduce cancer care disparities in people with mental illness, this study aimed to quantify psychiatric care providers' perceptions regarding issues that are insufficiently addressed or difficult to address. METHODS: Psychiatric care providers at 23 psychiatric hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 15 items with four categories related to insufficiencies/difficulties in cancer care for patients with mental illness on a five-point Likert scale. We analyzed the proportion of respondents who answered "insufficient/difficult" for each item. RESULTS: A total of 255 (76.3%) psychiatric care providers responded. For questions related to the skills and attitudes of psychiatric professionals, 48.3%-58.4% of respondents perceived that efforts for supporting cancer screening and treatment were insufficient. For the questions related to collaborations between cancer and psychiatric care providers, 75.3% of respondents perceived that inpatient visits between psychiatric and cancer hospitals were insufficient. For the questions related to in-psychiatric-hospital medical systems, 50.2%-87.2% of respondents perceived that support for screening, diagnosis/treatment, and palliative care for psychiatric inpatients were insufficient/difficult. 41.9%-57.4% of respondents perceived that social services in the community were insufficient. CONCLUSIONS: This study clarified the level of insufficiency/difficulty perceived by psychiatric care providers regarding issues related to cancer care for people with mental illness. Psychiatric care providers are required to have knowledge and skills in cancer screening and treatment. To improve access to cancer prevention, treatment, and palliative care, it may be helpful to establish systems to promote coordination between cancer hospitals and psychiatric hospitals.
