Introduction: Recently, community-based medical education has become widespread in Japanese medical schools, but the current status is not clear on a national level. A second survey of community-based medical education at all Japanese medical schools was conducted. The first survey was done in 2011. Methods: Members of the Council made and distributed a questionnaire to medical schools in order to assess the situation of community-based medical education as of April 2014. Results: A total of eighty schools responded. The number of schools which had community medicine programs was seventy-eight. In the first survey, the number was seventy-three. Seventy-seven schools gave community-based clinical clerkships. Discussion: The number of medical schools that had curriculum about community medicine was more than indicated in the first survey. Further research about the contents or implementation system of community-based clerkships is needed.

Introduction : The appropriate size of the regional coverage area for primary care in Japan has been unclear. The aim of this study was to determine the geographical distribution of primary care clinics for elderly ambulatory diabetic patients.
Methods : Using an insurance claims database, we extracted data of patients aged 75 years and older requiring ambulatory diabetic care in May 2010 in Ibaraki prefecture. The geographical distance from each municipal office to the clinics was analyzed.
Results : A total of 17,717 data points were extracted from the database. Data points that could not be mapped due to coding errors were eliminated, resulting in 17,144 (96.8%) data points that were ultimately analyzed. The median [25th-75th percentile] geographical distance was 5.5 [2.3-9.9] km. The distance was not related to municipal population, aging rate, or area size.
Conclusion : The coverage area for diabetic care in this primary care setting was estimated. For most elderly ambulatory diabetic patients, clinics are distributed within a 10-km radius area. Further investigation is needed to clarify primary care coverage areas that result in the most efficient use of medical resources.

Aim: To describe the current use of percutaneous endoscopic gastrostomy (PEG) in long-term care national health insurance facilities (special nursing homes for the elderly, health service facilities for the elderly, and long-term health care facilities), and assess whether its prevalence increased or not between 2007 and 2010. Methods: Based on data from the "Survey of Institutions and Establishments for Long-term Care" by the Ministry of Health, Labour and Welfare, we calculated the prevalence of residents with PEG in each type of long-term care facility in 2007 and 2010. Results: The prevalence of residents with PEG in 2007 versus 2010 was 5.8% versus 8.1% in special nursing homes for the elderly, 3.9% versus 5.9% in health service facilities for the elderly, and 18.4% versus 26.1% in long-term health care facilities. Among residents requiring level 3 or higher care, the prevalence of PEG increased in all three types of long-term care facility. Conclusion: From 2007 to 2010, the use of PEG increased among residents of long-term care facilities requiring level 3 or higher care.

Objective: We investigated the relation between fasting insulin (FI) and risk of cerebral infarction in a Japanese general population. Methods: The subjects were 2,610 men and women without past history of stroke or myocardial infarction and under treatment for diabetes, examined between 1992 and 1995 as part of the Jichi Medical School Cohort Study. The FI level was measured once at the baseline. Subjects were divided into quintiles by FI levels, and Cox’s proportional hazard model was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for cerebral infarction. Results: During an average of 11.1 years of follow-up, 87 participants developed cerebral infarction. Crude incidence rates of FI quintiles 1-5 were 4.69, 2.35, 1.85, 2.77 and 3.30 per 1,000 person-years, respectively. The multivariate-adjusted HRs for cerebral infarction were 2.33 (95% CI, 1.10 – 4.96) in quintile 1 (Q1), 1.25 (95% CI, 0.55 – 2.84) in Q2, 1.68 (95% CI, 0.76 – 3.70) in Q4 and 2.06 (95% CI, 0.94 – 4.47) in Q5, using Q3 as the reference. Conclusions: The lowest FI level was associated with increased risk of cerebral infarction and the association between FI and risk of cerebral infarction appeared to be a U-shaped relationship.

Objective : To analyze and reveal the contents of medical questionnaires distributed to nationwide general practice outpatients prior to their initial medical consultations.
Method : An observational study was conducted, based on questionnaire format. Sample questionnaires were collected from 85 hospitals registered with the Japan Primary Care Association.
Results : No standard format was found among the samples. A4 size forms (210 mm×297 mm) averaging 19.7 questions were in the majority, accounting for 68%. The distribution frequency of questionnaires reported by research cooperation centers listed 28 items (31.8%) concerning medical history, 19 items (21.6%) related to lifestyle, and 7 items (8.0%) referring to social and reproductive status.
Conclusion : This research assessed the qualitative value of medical questionnaires used in General Practice Clinics in Japan. The results indicate the nature of the medical information required by physicians prior to medical consultation.

Background: When analyzing regional disparities in healthcare resources, hospital accessibility is given little consideration. We surveyed accessibility from residential districts to medical institutions using GIS (Geographic Information System) and estimated Gini coefficient for each hospital distribution.
Methods: The subjects were 2,688 census mesh blocks ( “Cho-cho-aza” ) and 109 hospitals in Tochigi prefecture. The number of hospitals located within the road distances of 5 km, 10 km and 15 km from the geometrical center of each block was calculated using GIS. The Gini coefficient of each hospital per 100 residents was calculated among the regions located within 5 km, 10 km and 15 km from the geometrical center of the census mesh block.
Results: The population of each block was 748±1,067 (mean±SD), and the road distance to the nearest hospital from the center of each block was 4.3±4.5 km. The number of census mesh blocks with distances from the center of each block to the nearest hospital within 5 km, 5-10 km, 10-15 km and more than 15 km were 1909 (71.0%), 561 (20.9%), 139 (5.2%) and 79 (2.9%) respectively. The number of hospitals located within 5 km, 10 km and 15 km were 3.3±4.7, 8.3±8.6 and 14.4±11.4. Gini coefficients were 0.65, 0.52 and 0.43.
Conclusion: When analyzing regional disparities in healthcare resources, it is necessary to take into account not only the number of physicians and beds, but also accessibility. Gini coefficient is useful to estimate geographical distributions, and can be used as an indicator for improvement projects for hospitals.

Background: To date there had been no investigations using the International Classification of Primary Care, Second Edition (ICPC-2) at a clinic on an isolated island. In order to analyze health problems on the island, we investigated the reasons for visits, chronic illnesses, and the number of cases referred to other medical facilities using the ICPC-2.
Methods: The study was conducted over a 12-month period, from April 1, 2006 to March 31, 2007. Patient complaints/symptoms were classified according to ICPC-2, and diseases of patients who regularly visited the clinic as of November 2006 were investigated.
Results: Half of the patients that regularly visited the clinic had lifestyle-related or musculoskeletal diseases. On the first visit, several patients presented with cold, musculoskeletal, or skin symptoms. The specialist care to which the patients were most frequently referred was orthopedic surgery.
Conclusion: Physicians working at a clinic on an isolated island need to be able to control lifestyle-related diseases and provide initial treatment for musculoskeletal or skin diseases.

Background: Kampo medicine is the traditional form of medicine practiced in Japan, based on ancient Chinese medicine. Kampo medicine includes acupuncture and moxibustion, as well as herbal medicine. Physicians are allowed to prescribe ethical Kampo extract granules used in various formulae and practice acupuncture and moxibustion as acupuncturists and moxibustionists. However, medical schools do not offer many classes in traditional medicine. This study aims to analyze the use of Kampo formulae and practice of acupuncture and moxibustion in contemporary community health care.
Methods: The subjects (1538 clinicians) were graduates of Jichi Medical University on or after 1978, affiliated with a clinic or hospital with 300 beds or less on July 2010, and surveyed by postal questionnaire in October 2010.
Results: The effective response rate across Japan was 44% (n=679). Of these responders, 30%, 45%, and 22% were found to prescribe Kampo formulae regularly, occasionally, and rarely, respectively, in daily clinical care. Frequently prescribed formulae included shakuyakukanzoto, daikenchuto, kakkonto, rikkunshito, and hochuekkito. The reasons for using Kampo formulae given by 61% and 58% of the responders were, respectively, applicability for common diseases and ease of use for unidentified complaints and psychosomatic disease. Among the reasons for unlikely use, unclear applicability was chosen by 34% of the responders; difficulty stocking many formulations by 33%; and insufficient evidence of efficacy by 30%. Practitioners of acupuncture and moxibustion accounted for 4% of the responders. The main indications for acupuncture and moxibustion included low back pain and shoulder stiffness.
Conclusions: A large number of primary care physicians use Kampo formulae, implying their usefulness. However, one out of three physicians complains of unclear applicability and insufficient evidence of efficacy for Kampo formulae. In the future, appropriate education and research will be needed to clarify these issues.

Background: Helicobacter pylori (H. pylori) infection has been reported to be associated with cardiovascular risk factors by inducing chronic low-grade inflammation and by influencing endocrine and metabolic systems, as well as the immunological response evoked by the host. This study investigated the association between H. pylori infection and high density lipoprotein cholesterol (HDL-C) in Japanese subjects.
Methods: The study subjects were 2,632 (1,061 men and 1,571 women) living in rural areas in Japan. We checked H. pylori serum immunoglobulin G (IgG), HDL-C and other cardiovascular risk factors in 1999.
Results: The overall prevalence of H. pylori seropositivity was 53.5% and increased with age. The prevalence was higher among men (58.3%) than women (50.3%). H. pylori seropositive women were more associated with decreased HDL-C than seronegative subjects (58.1±13.6 vs. 60.5±14.7, p<0.01). Multiple linear regression analysis with H. pylori seropositivity, age, body mass index (BMI), fibrinogen, blood glucose, and smoking and alcohol habits demonstrated that H. pylori seropositivity was a significant predictor of decreased HDL-C in women. In addition, there was a linear decrease in HDL-C with increments in the value of H. pylori antibody titer as a continuous variable in women. This association remained in H. pylori seropositive women aged ≥50 years. Moreover, H. pylori seropositive women with BMI <22 were associated with decreased HDL-C, whereas the association was not significant in women with BMI ≥22.
Conclusions: We show that H. pylori seropositivity is associated with decreased HDL-C, especially in women with a lower BMI in rural areas of Japan.
