In-Hospital Death and End-of-Life Status Among Patients With Adult Congenital Heart Disease　- A Retrospective Study Using the JROAD-DPC Database in Japan.

BACKGROUND: The end-of-life (EOL) status, including age at death and treatment details, of patients with adult congenital heart disease (ACHD) remains unclear. This study investigated the EOL status of patients with ACHD using a nationwide Japanese database.Methods and Results: Data on the last hospitalization of 26,438 patients with ACHD aged ≥15 years, admitted between 2013 and 2017, were included. Disease complexity (simple, moderate, or great) was classified using International Classification of Diseases, 10th Revision codes. Of the 853 deaths, 831 patients with classifiable disease complexity were evaluated for EOL status. The median age at death of patients in the simple, moderate, and great disease complexity groups was 77.0, 66.5, and 39.0 years , respectively. The treatments administered before death to patients in the simple, moderate, and great complexity groups included cardiopulmonary resuscitation (30.1%, 35.7%, and 41.9%, respectively), percutaneous cardiopulmonary support (7.2%, 16.5%, and 16.3%, respectively), and mechanical ventilation (58.7%, 72.2%, and 75.6%, respectively). Overall, 70% of patients died outside of specialized facilities, with >25% dying after ≥31 days of hospitalization. CONCLUSIONS: Nationwide data showed that patients with ACHD with greater disease complexity died at a younger age and underwent more invasive treatments before death, with many dying after ≥1 month of hospitalization. Discussing EOL options with patients at the appropriate time is important, particularly for patients with greater disease complexity.

Somatic Changes Perceived by Patients With Heart Failure During Acute Exacerbation: A Qualitative Study Using Text Mining.

BACKGROUND: Patients with heart failure (HF) often inadequately perceive their symptoms. This may be because the medical terms do not match the somatic changes experienced by patients. To improve symptom perception, healthcare professionals must understand the somatic changes as perceived by patients. OBJECTIVE: This study aims to analyze patients' narratives about somatic changes in patients with HF by text mining and to clarify the overall description of somatic changes using patients' expressions. METHODS: Semistructured interviews were conducted on 21 patients hospitalized for acute exacerbation of HF. Qualitative data obtained from the interviews were analyzed by content analysis through text mining. RESULTS: Among the 21 patients, 76.2% were men. The mean (SD) age was 71.3 (13.7) years. The most frequently used terms were "breath," "distressed," "feet," and " ha-ha (gasping sound)" (46, 40, 29, and 28 times, respectively). The somatic changes noticed by patients could be categorized into medical jargon such as "dyspnea on exertion," "exercise intolerance," "fatigue," "paroxysmal nocturnal dyspnea," "frequent urination," "increased sputum," "weight gain," "feet and face edema," "abdominal edema," and "ankle edema." However, the expressions of somatic changes used by the patients were diverse. CONCLUSIONS: The findings of patient-specific expressions of symptoms suggest that there is a need to assess symptoms not only using medical jargon but also by focusing on patient-specific expressions.

Validation of the Japanese Transition Readiness Assessment Questionnaire.

BACKGROUND: For patients with childhood-onset chronic illnesses, the transition to adult care requires an understanding of transition readiness and the effectiveness of evaluation methods. However, no such psychometrically verified scales exist in Japan. This study aimed to develop a Japanese version of the Transition Readiness Assessment Questionnaire (TRAQ) and verify its validity and reliability. METHODS: The Japanese TRAQ was developed in accordance with international guidelines, followed by a preliminary survey to verify face validity among six participants who fulfilled the inclusion criteria. For the main survey 107 patients who fulfilled the same inclusion criteria were asked to complete the questionnaire and provide basic information. After descriptive statistics analysis, the construct validity of the Japanese TRAQ was tested using the t-test and Pearson's correlation coefficients. Cronbach's alpha coefficients were calculated to assess reliability. RESULTS: In the main survey, 76 participants with no missing data were included in the complete data analysis (40 males 36 females; mean age, 17.8 and 18.2 years, respectively). The mean total Japanese TRAQ score was 3.9. Cronbach's alpha coefficients were 0.94 overall and 0.8-0.96 for each of the four domains. The known-groups analysis revealed that older participants (r = 0.23, P = 0.044), those having knowledge of the disease name (yes [4.0] vs no [3.4]; P < 0.001), and making unaccompanied hospital visits (with parent/others [3.7] vs alone [4.4]; P < 0.001) had significantly higher total TRAQ scores. CONCLUSION: We confirmed preliminarily the validity and reliability of the Japanese TRAQ.

Incidence and Prevalence of Infectious Diseases and Their Risk Factors among Patients Who Use Visiting Nursing Services in Japan.

This study aimed to clarify the incidence of infectious diseases and the associated risk factors among patients who use visiting nursing services in Japan. We conducted a one-year follow up cohort study with 419 participants. The incidence and period prevalence rate of infectious diseases were 0.63 and 15.0%, respectively. In the multiple logistic regression analysis, the presence of chronic respiratory failure, Parkinson's disease, dermatosis other than pressure ulcers, and the inability to perform oral self-care were significantly related to the contraction of an infectious disease.

Preferences Regarding Transfer of Patients With Congenital Heart Disease Who Attend Children's Hospital.

BACKGROUND: The aim of this study was to determine preferences regarding transfer of patients with congenital heart disease (CHD) attending a children's hospital in Japan and related factors. Methods and Results: We conducted a self-administered questionnaire survey with CHD patients >15 years of age treated at the pediatric cardiology outpatient clinic of a children's hospital. Logistic regression analysis was used to identify factors related to patient preferences regarding the transfer. One hundred and eleven of the 122 patients given a questionnaire provided valid responses (valid response rate, 91.0%). Sixty-six subjects (64.9%) reported "not being told anything specific" by their physicians about the transfer from the children's hospital, and 72 (59.5%) stated that they "wished to continue attending the children's hospital". Visiting outpatient clinic with parents (OR, 11.00; 95% CI: 2.01-60.97), having low uncertainty about continuing to attend the children's hospital (OR, 0.95; 95% CI: 0.92-0.98), and having high uncertainty about leaving the current physician (OR, 1.04; 95% CI: 1.01-1.07) were significantly related to the patient's wish to continue to attend the children's hospital. CONCLUSIONS: There is a need to improve patient education regarding the opportunities for transfer, and to develop a systematic transition program for children's hospitals and aligned specialized adult CHD centers.

Social independence of adult congenital heart disease patients in Japan.

BACKGROUND: As treatment outcomes for congenital heart disease (CHD) have improved, the social independence of adult CHD patients has become a key goal. The aims of this study were therefore to (i) determine the relationship between social independence and psychological profile, and (ii) identify patient anxieties, difficulties, and demands related to life in society. METHODS: A total of 143 patients aged ≥15 years with physical disability certificates were selected using a questionnaire distributed by a patients' association. Each participant was asked about employment status, income, and receipt of disability pension as a social independence index, and about financial and psychological distress as a psychological status index. Furthermore, each participant was asked to freely describe his or her difficulties, anxieties, and needs pertaining to life in society. RESULTS: The subjects were 15-73 years old. Seventy-one (50%) were female, and 94 (66%) had a grade 1 physical disability certificate. Fifty-nine subjects (41%) were employed, 37 (26%) were unemployed, and 45 (31%) were students. Of those employed, 34 subjects (58%) reported annual individual income ≤2 million yen. Frequent hospital visits, low total household income, low individual annual income, work dissatisfaction, and receipt of a disability pension were associated with poorer psychological profile. In an open description section, subjects expressed desires for better pension systems, support for medical fees, and employment support. CONCLUSIONS: Because financial issues can adversely affect the psychological profiles of adult CHD patients, enhancement of social welfare and employment support may improve their social independence.

Difficulties in Performing Mesalazine Enemas and Factors Related to Discontinuation Among Patients With Ulcerative Colitis.

Current first-line treatment of ulcerative colitis consists of a combination of mesalazine enemas and oral mesalazine; however, many patients may discontinue mesalazine enemas. In this single-center, cross-sectional study, 165 outpatients with ulcerative colitis completed a self-administered questionnaire regarding the frequency of mesalazine enemas, difficulties in performing these enemas, and factors possibly associated with their discontinuation, as well as patient clinical and demographic characteristics. Of 165 patients, 34 (20.6%) discontinued mesalazine enemas because of a lack of efficacy. Five of the 13 items assessing difficulties were answered affirmatively by the majority of patients. Discontinuation of enema application was associated with a perceived lack of efficacy, four or more bowel movements per day, and lower scores on measurement of the doctor-patient relationship. Application of mesalazine enemas by patients with ulcerative colitis may be improved by discussions with peers and healthcare professionals and by adjusting the frequency of application or the time of starting the enema based on worsening of ulcerative colitis.

Nationwide Survey of the Transfer of Adults With Congenital Heart Disease From Pediatric Cardiology Departments to Adult Congenital Heart Disease Centers in Japan.

BACKGROUND: Current Japanese transfer practices for adult congenital heart disease (ACHD) patients in pediatric departments are elucidated in this study. The focus was on 149 facilities (from the Japanese Society of Pediatric Cardiology and Cardiac Surgery Subspecialty Board and the Japanese Association of Children's Hospitals and Related Institutions). One hundred and thirteen facilities were surveyed and the response rate was 75.8%. METHODS AND RESULTS: Twenty-six facilities (23.0%) treated ≥200 outpatients annually; 48 facilities (42.9%) treated <50 outpatients. Only eight facilities admitted ≥50 inpatients; 61 facilities (54.0%) admitted <10 inpatients. Nine facilities fulfilled international regional ACHD center criteria. The estimated median number of patients receiving outpatient pediatric department follow up was 33,806. Sixty facilities (53.6%) treated patients in pediatric departments after they reached adulthood. Of 49 facilities that transferred patients, the transfer was most commonly to another department in the same facility (20 facilities; 40.8%), typically the adult cardiology department (29 facilities; 59.2%). In future, 55 facilities (48.7%) desired the transfer of patients to regional ACHD centers, while 34 facilities (30.1%) preferred to continue treating patients in the pediatric department. CONCLUSIONS: The number of regional ACHD centers offering sufficient outpatient and inpatient care is limited; transfer from pediatric departments is not standard in Japan. Role division clarification between regional ACHD centers and other facilities and cooperative network establishment including transitional care programs is necessary. (Circ J 2016; 80: 1242-1250).

Nationwide Survey on Transitional Care for Patients With Childhood-Onset Cardiomyopathy in Japan.

Background: Individuals transitioning into adulthood require age-appropriate medical care and delegation of decision-making authority from their parents to the patients themselves. Although there have been multiple observational and interventional studies on transitional care for patients with congenital heart disease (CHD) in the cardiovascular field, transitional care specific to childhood-onset cardiomyopathy (CM) remains unaddressed. Methods and Results: A nationwide questionnaire-based survey was performed in the pediatric cardiology departments of 151 facilities in Japan. Responses were obtained from 100 (66%) facilities with low transfer rates (<5%) for childhood-onset CM cases. The comparison between CHD-transferring and non-CHD-transferring facilities revealed a significantly higher transfer rate (83.9%) for childhood-onset CM cases in the CHD-transferring facilities (P<0.001). Regarding the transition programs, 72 (72%) facilities do not offer any programs for CM, while most (92%) facilities recognize its necessity. Finally, only 19 (19%) facilities provided a transition program, 10 of which were CHD based. Conclusions: To the best of our knowledge, this is the first study to demonstrate the poor transition/transfer care status of patients with childhood-onset CM in Japan. The transfer rate of CMs was lower than that of CHDs, and transition programs were less available. Referring to the system established for CHD could help develop a successful transitional care system for CM.

Development of self-care educational material for patients with heart failure in Japan: a pilot study.

This study assessed the need for information regarding heart failure and self-care, developed self-care educational material, and investigated the feasibility of the material. A total of 22 hospitalized heart failure patients (mean age: 63 years) completed a self-administered questionnaire. We found that more than 90% of patients desired information, particularly about heart failure symptoms, time to notify healthcare providers, prognosis, and exercise/physical activity. After examining the eight existing brochures for Japanese heart failure patients, we developed self-care educational material. This was based on heart failure guidelines and on the results of our inquiry regarding information needs. Finally, a pilot study was conducted in nine hospitalized heart failure patients (mean age: 57 years). None of the patients had difficulty reading or understanding the educational material. The self-administrated questionnaire survey revealed that comprehension of the following improved after the educational sessions with the material: heart failure symptoms, medication, weighing, sodium intake, and fluid intake (P < 0.05). In conclusion, heart failure patients have a great need for information about heart failure. Our pilot study suggests that the material was readable and had a beneficial effect on heart failure comprehension.

Difficulties in taking aminosalicylates for patients with ulcerative colitis.

Aminosalicylates are effective in inducing remission and are also useful in preventing relapse of ulcerative colitis (UC); however, previous studies have reported a 30%-45% rate of nonadherence to prescribed medication among UC patients. Enumerating and conceptualizing the difficulties in taking aminosalicylates enable us to assess and support patients more effectively. The aim of this study was to investigate the difficulties in taking aminosalicylates among Japanese UC patients and explore factors related to these difficulties. Outpatients with UC (n = 242) completed a questionnaire supported by a semistructured interview on the basis of a literature review. Twelve items about difficulties in taking aminosalicylates were processed by factor analysis and the related factors regarding difficulties were analyzed. The following three independent domains were identified: Domain 1: diminished sense of priority for medication; Domain 2: concern about side effects; and Domain 3: burden of taking the prescribed drug. Factors related to the difficulties in taking aminosalicylates included the disease state, psychosocial factors, and demographic characteristic variables. On the basis of the results, we recommend the creation and validation of a program aimed at decreasing the difficulties in taking aminosalicylates.

Content validity of the Japanese version of the health literacy and resiliency scale for youth with chronic illness.

Health literacy, which is the ability to find, understand, and use information as well as services to make informed health-related decisions and actions, is essential for ensuring that youths with chronic diseases adapt to and live with their illnesses. However, in Japan, an appropriate approach for measuring health literacy levels among children is yet to be developed. The Health Literacy and Resiliency Scale for Youth (HLRS-Y) was developed by Kathy Bradley-Klug and her colleagues to assess health literacy, resiliency, and self-advocacy/support among youths aged between 13 and 21 years with chronic illnesses in the United States of America (United States). In this study, we aimed to develop a Japanese version of the HLRS-Y and evaluate its content validity. After receiving approvals from the original authors, four nurse researchers with expertise in pediatric nursing translated the scale into Japanese (forward translation). Afterwards, the appropriateness of each expression was examined by a pediatrician. Next, an English native speaker translated the expressions into English (back-translation). We reported the back-translated version of the scale to the original authors to confirm its accuracy. The scale's content validity index (CVI) was evaluated by health professionals working in the fields of pediatric, transitional, and adult health care. The participants rated the items using a four-point scale. Each item was evaluated for a minimum item-level content validity index (I-CVI) value of 0.78. The scale's total and subscale validities were evaluated using a minimum scale-level content validity index based on an average (S-CVI/Ave) value of 0.90. Eleven participants responded to an online survey for evaluating content validity. Of the 36 items, 34 met the I-CVI criteria. Two items did not exceed the criteria's value, but they approximated it. The values of the S-CVI/Ave were 0.96, thereby satisfying the criteria's requirements. Based on the results, it was confirmed that the Japanese version of the HLRS-Y had good content validity. Future studies should examine the factor validity, known group validity, and reliability of this scale.

Efficacious interventions for improving the transition readiness of adolescents and young adult patients with chronic illness: A narrative review of randomized control trials assessed with the transition readiness assessment questionnaire.

Objective: We inspected efficacious interventions to improve the transition readiness of adolescent and young adult patients with childhood-onset chronic illnesses using the Transition Readiness Assessment Questionnaire (TRAQ). Methods: Our narrative review was conducted on randomized control studies assessed with TRAQ for outcome measurement before and after the interventions. We included all patients with chronic diseases. We searched eight electronic database(s): Allied and Complementary Medicine Database (AMED) Allied and Complementary Medicine, BioSciences Information Service of Biological Abstracts (BIOSIS) Previews, Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Library, Embase, Ichu-shi, Medline, and Web of Science. The text words for the search of data sources were as follows: "("transition readiness assessment questionnaire" OR TRAQ) AND 2011/01:2022/06[DP] AND (clinical AND trial OR clinical trials OR clinical trial OR random* OR random allocation)." More studies were identified from the references in our reported study. This data set was independently cross-checked by two reviewers. Results: We identified 261 reports and collected three articles. The target diseases were type-1 diabetes, congenital heart disease, cystic fibrosis, and inflammatory bowel disease. All the studies excluded patients with intellectual disabilities. The age of the participants was distributed between 12 and 20 years. Nurse-provided web-based intervention of transition readiness was constructed using digital resources in two studies. The intervention ranged from 6 to 18 months. All the interventions were efficacious in improving transition readiness assessed with TRAQ scores, except for the self-advocacy score. Conclusions: We obtained three randomized control studies with TRAQ for outcome measurement. In two studies, web-based and nurse-led organized interventions were shown to improve transition readiness.

Hospital Support for Siblings of Children With Illness in Japan.

Recent years have seen increased attention to the needs and support of siblings of children with chronic illness, and reports of intervention studies on siblings are gradually increasing worldwide. In Japan, the basic policy approved by the Cabinet in 2021 of The Basic Law for Child and Maternal Health and Development stipulates promoting support for the siblings of children with chronic illness, medical care, and disabilities. Simultaneously, practical reports are emerging. However, reports on the actual state of sibling support at medical institutions in Japan are limited. This study aimed to describe the actual state of support for siblings of children with illness in Japanese medical institutions using a cross-sectional design. Responses were obtained from 207 of 484 registered training facilities for Board-Certified Pediatricians of the Japan Pediatric Society through anonymous questionnaires investigating the actual state of siblings' support. Descriptive statistics were calculated, and the state of siblings' support was described. Fifty-two participants (25.1%) answered that the entire ward, including two outpatient departments, provided siblings' support, while 37 (17.9%) answered some staff made an effort, and 117 (56.5%) did not. Support mentioned included conversing with siblings, actively speaking to siblings, calling siblings' names, and counseling care through the parents. Of the 45 cases (21.7%) where siblings were invited to events and gatherings, 10 (22.2%) were siblings-centered events. Some cases involved collaboration with local sibling support groups such as non-profit organizations. This study clarified the actual state of siblings' support, and further expansion of this support is required.

Status and future needs of regional adult congenital heart disease centers in Japan.

BACKGROUND: Although the prevalence of adult congenital heart disease (ACHD) in Japan continues to rise, the number and geographic distribution of facilities potentially serving as regional ACHD centers remains unknown. We examined trends in ACHD care in Japan to identify needs and to determine potential regional responses to this growing patient population. METHODS AND RESULTS: A descriptive, cross-sectional, nationwide survey was conducted to assess the status and needs of cardiology specialists related to providing ACHD care. Questionnaires were mailed to 138 cardiology departments located in 8 geographical regions throughout Japan; respondents were asked to document the status and future direction of ACHD care for each facility. Of the 109 facilities that responded, approximately one-third currently treat or plan to treat all ACHD patients. Fourteen facilities (12.8%) fulfilled all criteria for becoming regional ACHD centers. Although each regional center was projected to serve a population of 9.1 million, in 2 regions, no centers possessed the necessary care structure. CONCLUSIONS: Our findings revealed a shortage of adult cardiologists dedicated to ACHD care. Moreover, basic as well as formal fellowship ACHD training was deemed necessary. In Japan, the number of potential regional ACHD centers has just reached international standards. However, based on the geographic gaps documented here, a strategy other than regional centralization might be required to deliver adequate ACHD care to rural areas.

Gender differences in HIV testing service visits and its related factors among adults: a cross-sectional study in Homa Bay, Kenya.

INTRODUCTION: at least 90% of people living with human immunodeficiency virus (HIV) were expected to know their HIV status by 2020. However, only 84% are aware of their status. This study determined the frequency of HIV testing services visits (HTS) and its related factors to HTS visits among adults in Homa Bay County, Kenya. METHODS: this was a cross-sectional study. Quantitative and qualitative data were collected. A backward stepwise logistic regression analysis was conducted for quantitative data by gender. Qualitative data were thematically categorised into factors of HTS visits by gender. RESULTS: a total of 645 adults participated in quantitative survey and 17 in qualitative survey. There were no gender differences in the frequency of HTS visits (males=56.3%; females= 58.7%, P=0.785). The frequency of visits was however significantly different between the rural-based (Rachuonyo North=87.5%; Ndhiwa=58.7%) and urban-based (Homa Bay Town=36.8%) facilities at P<0.001. In males, HTS visits were positively associated with ´being in Protestant church´, ´partner´s attitude´, and ´being accompanied by a friend to HTS´. ´Distance to HTS´ was negatively associated with HTS visits in males. For females, 'sexual intercourse in the past 2-5 months´ was positively associated with HTS visits. ´Being in a polygamous marriage´, ´not married´, ´community HIV testing´, and ´affordability of transport cost to HTS centre´ were negatively associated with HTS visits. CONCLUSION: there were no gender differences in the frequency of HTS visits. Social position for males and position in the family for females are suggested as the factors influencing HTS visits in Homa Bay County.

Objective and Personalized Assessment of Disease-Related Knowledge Among Patients With Congenital Heart Disease　- Development and Validation of the Japanese Version of the Leuven Knowledge Questionnaire for Congenital Heart Disease.

Background: Disease understanding in patients with congenital heart disease is important in transitional and lifelong care. This study aimed to develop the Japanese version of the Leuven Knowledge Questionnaire for Congenital Heart Disease (LKQCHD) and identify factors associated with disease-related knowledge. Methods and Results: After confirming the content and face validity of the scale, a questionnaire including the LKQCHD was distributed to 59 eligible patients aged >16 years attending a university hospital. For the 58 participants who responded (30 males, 28 females; median age 22 years), the mean (±SD) LKQCHD total score was 53.7±15.4, with mean (±SD) scores for each domain as follows: Disease and Treatment, 68.3±19.7; Preventing Complications, 45.8±19.0; Physical Activity, 74.1±34.1; Sex and Heredity, 37.9±35.4; and Contraception and Pregnancy, 40.2±29.1. Regarding known-groups validity, we found a positive correlation between the LKQCHD score and age (ρ=0.268, P=0.042), and a significantly low LKQCHD score in the moderate/severe disease group (η2=0.131, P=0.021). Regarding convergent validity, the LKQCHD score was positively correlated with the total and subscale scores of the Resilience Assessment Tool (r=0.213 [P=0.109] and r=0.405 [P=0.002], respectively). Conclusions: We confirmed the validity of the Japanese version of the LKQCHD, concluding that patient education regarding long-term complications, prevention methods, heredity, pregnancy, and childbirth is needed.

Characteristics of patients with adult congenital heart disease treated by non-specialized doctors: The potential loss of follow-up.

BACKGROUND: In the treatment of adult congenital heart disease (ACHD), the transfer of patients from pediatric cardiologists to ACHD cardiologists is of relevance. However, little is known about the clinical courses of ACHD patients that have been referred by non-CHD-specialized doctors (n-CSDs). METHODS: This retrospective cohort study included 230 patients (average age: 37 ± 15.2 years, male: 97) who were referred to a single specialized ACHD center between April 2016 and July 2019. We compared the characteristics and clinical courses between patients referred by n-CSDs and those referred by CHD-specialized-doctors (CSDs). RESULTS: Overall, 121 (53%) patients were referred by n-CSDs. Among them, 91 (75%) patients were referred by adult cardiologists. Univariate analysis showed that the patients referred by n-CSDs were older than those referred by CSDs (41.6 ± 16.3 vs. 32.0 ± 12.0 years, p < 0.01), were more likely to have simple CHD, and less likely to have severe CHD (27.0% vs. 12.8% and 16.5% vs. 40.4%, respectively, p < 0.01). Patients referred by n-CSDs were also more likely to have a history of loss of follow-up (16.5% vs. 3.7%, p < 0.01) and to require invasive treatments after referral, including cardiac surgeries and transcatheter interventions (47.9% vs. 26.6 %, p < 0.01). Notably, unintended invasive treatments that were not designated by the referring doctors were more frequently required in patients with moderate complexity referred by n-CSDs (50.0% vs. 23.3%, p = 0.02). CONCLUSIONS: Patients with moderate CHD complexity referred by n-CSDs are more likely to require unintended invasive treatments. Referrals to specialized ACHD centers may be most beneficial for these patients.

Perceptions of physicians and nurses concerning advanced care planning for patients with heart failure in Japan.

BACKGROUND: The importance of advance care planning (ACP) has been recognized in the palliative care of patients with heart failure. It is necessary for dissemination of ACP to characterize the perceptions of physicians and nurses towards ACP and to promote mutual understanding. The aim of this study is to investigate the perceptions of physicians and nurses concerning ACP for patients with heart failure. METHODS: We conducted a self-administered questionnaire survey with physicians and nurses who belonged to the 427 certified institutions for implantable cardioverter defibrillator (ICD) and/or cardiac resynchronization therapy (CRT) in Japan. The self-administered questionnaire was originally designed based on the guidelines on palliative care or ACP and previous studies on the barriers of ACP. We asked the participants the recognition about condition/timing to implement ACP, Content of care to be implemented in ACP, and barriers against implementing ACP. A Mann-Whitney U test was performed and r value was calculated an effect size (ES) in order to evaluate the characteristic perceptions among physicians and nurses. RESULTS: Valid responses were obtained from 163 physicians (38.2%) and 208 nurses (48.7%). Regarding the condition/timing, nurses tended to recognize that ACP should be implemented from earlier clinical stages than physicians. Regarding the contents of ACP, both physicians and nurses placed emphasis in assessing the patient's perception of disease progression. The biggest difference was found in the item "Ask patient about what has been important in life so far"; 78.6% of physicians but 94.2% of nurses chose "it must/should be implemented" (Cohen's r=0.31). Regarding the barriers, both physicians and nurses recognized the difficulty in prognosis prediction. The biggest differences were found in the items "Medical staff does not know how to implement ACP for patients and their families" (45.6% of physicians and 70.4% of nurses chose "strongly agree/agree", r=0.27), and "There is disagreement regarding care goals among team members of different professions" (18.5% in physicians and 43.3% in nurses, r=0.27). CONCLUSIONS: It is suggested that discussions and further studies are necessary concerning the condition/ timing of implementing ACP from early stages, specific manuals/protocols and recommendation on rolesharing within a multidisciplinary team.
