Integrating Community Care for the Prevention and Treatment of Diabetes.

Introduction: This paper describes 'Project 8', a campaign that aims to reduce glycated haemoglobin (HbA1c) to 8% or more among patients with diabetes mellitus, utilising healthcare professionals and local community residents and focusing on education and support. The study is based in Uonuma-a small rural city in Japan with a declining population and an increased number of older people. Description: 'Project 8' began in Uonuma's Koide Hospital in 2008. The Uonuma School for Community Health and Social Care was established in 2011 with the cooperation of a clinic's general practitioner. Medical students, trainees, doctors, and health care professionals have been holding 'open schools' (daytime lectures) and 'night schools' (evening lectures) to educate the community residents about various health issues. Through repeated lectures, the residents have been made aware of lifestyle-related diseases, including diabetes, and the meaning of 'Project 8'. Discussion: Over the last decade, the hospital's campaign has expanded within the community, showing a statistically significant reduction of diabetic patients with HbA1c ≥ 8%, which successfully deferred the start of dialysis for many of them. Conclusion: Well-integrated community care requires interprofessional education, collaborative practice, and the participation of community residents in health education.

Regional Disparities in Adherence to Guidelines for the Treatment of Chronic Heart Failure.

Objective The incidence of chronic heart failure (CHF) is likely to keep increasing in Japan as the population ages, placing increased burdens on medical facilities, particularly on the limited numbers of rural hospitals. We explored the appropriateness of CHF treatment in rural areas in Japan. Methods We compared rates of adherence to therapeutic guidelines for CHF between residents with a left ventricular ejection fraction <35% living in urban areas (n = 207) and those in rural areas (n = 180). Treatments included pharmacological [beta-blockers, angiotensin-converting enzyme inhibitors (ACEi)/angiotensin II receptor blocker (ARB), mineralocorticoid receptor antagonist (MRA) and anticoagulants for atrial fibrillation] and non-pharmacological [implantable cardioverter defibrillator (ICD)/cardiac resynchronization therapy (CRT), cardiac rehabilitation and HF education] approaches. Patients This study included 387 patients with CHF, prior myocardial infarction or cardiomyopathy, and a left ventricular ejection fraction (LVEF) <35% as determined by echocardiography. Results The respective rates of treatments administered in urban and rural areas were as follows: beta-blockers, 91.3% vs. 61.7% (p<0.05); ACEi/ARB, 86.5% vs. 68.3% (p<0.05); MRA, 74.4% vs. 59.4% (p<0.01); anticoagulants, 100% vs. 86.5%, (p<0.05); ICD/CRT, 45.4% vs. 5.0% (p<0.05); cardiac rehabilitation, 32.4% vs. 13.3% (p<0.05) and HF education, 33.3% vs. 32.8% (p=0.75). Conclusion Regional disparities in treatment for CHF persist, even in Japan. Improvements in the use of guideline-directed treatment in rural areas might improve the outcomes for CHF patients.

Performance of the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) for depression in primary care.

OBJECTIVE: To assess the performance of the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) for depression in primary care. METHODS: Participants in both phases completed the J-PHQ-9, while patients in the second phase also completed the SF-8 (the short form for the health-related QOL scale SF-36). Subjects (n = 284; male = 107, female = 177) had to return the questionnaires to their health care professional within 48 hours and undergo a diagnostic evaluation interview based on the Japanese version of M.I.N.I-Plus. RESULTS: 93 patients were diagnosed as having major depressive disorder (MDD). In the J-PHQ-9, the optimal cutpoint ≥ 10 had sensitivity of 90.5% and specificity of 76.6%. As for the categorical algorithms, the sensitivity was 80.6%; specificity was 89.5%, and a positive likelihood ratio of 7.7. The Stratum-specific likelihood ratios (SSLRs) of the J-PHQ-9 scores of 0-9, 10-14, 15-19, and 20-27 for major depression were 0.10 (95% CI: 0.05-0.20), 1.67 (95% CI: 1.02-2.76), 5.41 (95% CI: 2.87-10.22), and 11.98 (95% CI: 5.39-26.63), respectively. The relationship between the severity of J-PHQ-9 and the MCS of SF-8 was significant (χ 2 ＝ 85.72, df = 4, P ≤ 0.0001). CONCLUSIONS: This study has validated the J-PHQ-9 as a useful tool for the assessment of MDD in primary care in Japan.

The amplification of somatic symptoms in upper respiratory tract infections.

To assess the cultural differences in the role of somatosensory amplification in Japan and North America, we re-examined the role of psychological amplification of objective physical symptoms, as measured by the Somatosensory Amplification Scale (SSAS), in 82 Japanese patients with upper-respiratory tract infections. Anxiety and depression were measured with the Hospital Anxiety and Depression Scale (HADS). We determined the association among continuous variables using the Spearman correlation coefficient. Next, we used multiple regression analysis and selected all symptoms as independent variables. The SSAS was significantly associated with all somatic symptoms. It was also closely related to discomfort, but the SSAS was not significantly correlated with either anxiety or depression. All somatic symptoms were not significantly correlated with the objective physical findings. Multiple regression analyses indicated that amplification by SSAS was a statistically significant predictor of the patient's somatic symptoms and discomfort. The objective findings did not significantly predict the patient's symptoms. Our study provides some empirical evidence regarding psychological amplification of objective physical symptoms, as measured by SSAS, in Japanese patients with upper-respiratory tract infections. Our findings suggest that there is no difference in the role of amplification of bodily sensations between Japanese and North Americans.
