Background. Offspring of type 2 diabetic patients are at a high risk of type 2 diabetes. Information on diabetes genetic susceptibility and prevention should be supplied to the offspring. Methods. A six-page booklet on diabetes genetic susceptibility and prevention was distributed to 173 patients who ere ordered to hand it to their offspring. The patients answered a self-administered questionnaire on booklet delivery and attitudinal and behavioral changes toward diabetes and its prevention in themselves and their offspring. Results. Valid responses were obtained from 130 patients. Forty-nine patients had actually handed the booklet. Booklet induces more relief than anxiety. From the patients view, favorable attitudinal and/or behavioral changes occurred in more than half of the offspring who were delivered the booklet. Conclusion. The booklet worked effectively on attitudes and behaviors toward diabetes and its prevention both in patients and their offspring. However, the effectiveness of patients as information deliverers was limited.

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.

Background: Palliative care service (PCS) has been shown to be utilized less in patients with leukemia and malignant lymphoma than in those with solid tumors. Previous studies have suggested hematologists’ limited awareness of PCS as one of the reason for low PCS referral in hematology. However, little is known about such an awareness and potential barriers to collaboration between hematologists and PCS. Aim: The present study aimed to assess ematologists and palliative care specialists’ perception about the roles of the hospital-based palliative care team (HPCT) and the barriers to collaboration between hematologists and palliative care teams on relapse or refractory leukemia and malignant lymphoma patients’ care Materials and Methods: A qualitative study was conducted using semistructured interviews with hematologists and palliative care specialists recruited from a hospital that provides hematology and palliative care by the HPCT. Data were evaluated via content analysis. Results: The study included 11 hematologists and 10 palliative care specialists. Our results revealed that they shared many common perceptions about the roles and expectations of the HPCT. Additionally, 7 categories of barriers to collaboration were identified, including not feeling the need to refer, the difficulty in referral timing, the lack of aggressive approach, the negative image of the HPCT, the need for hematologic malignancy-oriented management, the lack of communication, and others. Conclusion: We have identified hematologists’ and palliative care specialists’ perceptions of the HPCT’s roles and the barriers to their collaboration. A better understanding of such barriers may lead to effective collaboration between hematologists and the HPCT.

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 Childrens Hospitals and Related Institutions). One hundred and thirteen facilities were surveyed and the response rate was 75.8%. METHODSANDRESULTS 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).

Facilities for Patient Care

Ryota Ochiai; Atsushi Yao

The central role in a care delivery system for adult congenital heart disease (ACHD) should be performed by specialized ACHD centers. They should be well-staffed and equipped high volume centers, both for outpatient and inpatient care. The population that each specialized ACHD center should cover is assumed to be from 2 to 10 million. They will also provide education and training for the ACHD specialist and promote research and innovation. Methods for linking the roles of specialized ACHD centers and related facilities differ depending on the regional medical care system and medical resources, and appropriate methods should be found to suit each region. It is essential to clarify the preferences of the patients themselves in terms of treatment systems, giving due consideration to geographical access to medical institutions; it is also important for medical personnel to support such actions, with the expectation of political action by patient associations. Patients with ACHD may be examined in parallel by both distant specialized ACHD centers and a local nonspecialized facility, which complicates the monitoring of patient behavior. Therefore, it is essential to build a comprehensive database that incorporates specialized ACHD centers and nonspecialized facilities, as well as pediatric medical institutions such as children’s hospitals, to ascertain the behavior adopted by patients with ACHD, the medical services these patients are using, and the outcomes achieved by each facility. Even if appropriate medical facilities are established, they are meaningless unless the facilities are utilized by patients. Therefore, transition programs must be further developed in the future. At the same time as transition programs are developed for individuals and groups, research is needed to evaluate the effectiveness of these programs.

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.

ObjectiveTo develop both a revised version of the Diabetes Diet-Related Quality of Life (DDRQOL-R) scale that can be applied to patients with nephropathy and a short form of the DDRQOL-R.MethodA total of 184 outpatients with type 2 diabetes were asked to complete the self-administered DDRQOL-R scale to confirm its psychometric properties. A short-form version was developed, based on two methods: the result of the developed DDRQOL-R scale and consensus using the Delphi method among medical experts.ResultsCorrelations were generally strong between the DDRQOL-R factors extracted by factor analysis and each SF-36 subscale. Cronbach’s α coefficients were at least 0.7, and intraclass correlation coefficients were between 0.59 and 0.78. The nine items that showed high factor loadings were also assessed as important by the medical experts and were selected for the short form of the scale. The reliability and validity of the short form were found to be similar to those of the DDRQOL-R scale.DiscussionOur findings indicate that the DDRQOL-R scale and its short form have acceptable reliability and validity. The revised version is highly versatile, and the short form can be conveniently administered.
