Objectives : To determine factors related to peoples' preference for visiting home-doctors when experiencing new health problems.
Method : A questionnaire survey was conducted of people receiving annual health checkups in municipalities in the vicinity of Jichi Medical University Hospital. We surveyed personal characteristics, test equipment, having of a home-doctor, and answers to an assumed scenario (asking about willingness to visit a home-doctor in case of getting certain health problems).
According to the responses to the scenario, we divided the subjects into two groups (a home-doctor group: visiting a home-doctor; and a specialist group: not visiting a home-doctor) and statistically compared the two groups.
Results : In the analytic sample of 1,829, the home-doctor group numbered 1,097 individuals (60%) and the specialist group numbered 732 individuals (40%). The home-doctor group statistically had more home-doctors than the specialist group (adjusted odds ratio, 95% confidence interval: 2.47, 2.00-3.05).
More home-doctors in the home-doctor group had test equipment than home-doctors in the specialist group: Gastrointestinal test equipment (gastroscopy, colonoscopy, or ultrasonography) (adjusted odds ratio, 95% confidence interval: 1.39, 1.06-1.83).
Conclusion : We revealed two factors relating to the preference for visiting home-doctors: First, those people had home-doctors, and, second, the home-doctors had test equipment.

The aim of this article is to describe the 2017 revised consensus criteria for the clinical diagnosis of dementia with Lewy bodies (DLB) with future directions for the diagnostic criteria. The criteria for the clinical diagnosis of probable and possible DLB were first published as the first consensus report in 1996 and were revised in the third consensus report in 2005. After discussion at the International DLB Conference in Fort Lauderdale, Florida, USA, in 2015, the International DLB Consortium published the fourth consensus report including the revised consensus criteria in 2017. The 2017 revised criteria clearly distinguish between clinical features and diagnostic biomarkers. Significant new information about previously reported aspects of DLB has been incorporated, with increased diagnostic weighting given to rapid eye movement (REM) sleep behavior disorder (RBD) and iodine-123-metaiodobenzylguanidine (MIBG) myocardial scintigraphy. Future directions include the development of the criteria for early diagnosis (prodromal DLB) and the establishment of new biomarkers that directly indicate Lewy-related pathology, including α-synuclein imaging, biopsies of peripheral tissues (skin, etc.) for the demonstration of α-synuclein deposition, and biochemical markers (cerebrospinal fluid/blood), as well as the pathological evaluation of the sensitivity and specificity of the 2017 revised diagnostic criteria. In conclusion, the revised consensus criteria for the clinical diagnosis of DLB were reported with the incorporation of new information about DLB in 2017. Future directions include the development of the criteria for early diagnosis and the establishment of biomarkers directly indicative of Lewy-related pathology.
