“…Additionally, the rate of pure “attended deaths at home” should be used as an objective outcome indicator in assessing the prevalence of home care. A recent innovative research analyzed the medical care provided to end-of-life elderly patients, based on the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) [14]. The spread of utilization of NDB will support the imperfection of the vital statistics stated above and elucidate the actual status of home care in Japan.…”

BackgroundNo study has yet been performed on the importance of the rate of pure “attended deaths at home,” excluding examined deaths subjected to a postmortem examination. Therefore, in the present study, we investigated actual state of pure “attended deaths at home,” in order to provide reference data for the future development of end-of-life care at home.MethodsWe performed a detailed survey in Yokohama City according to the type of death, age, and underlying cause of death in cases of home deaths, based on the detailed version of the Vital Statistics Survey Death Forms. Then, we divided deaths occurring in each municipality in Kanagawa Prefecture into two categories: “examined deaths” or “attended deaths,” which were also stratified by the place of death, based on the Vital Statistics, and data on number of death cases subjected to postmortem examination from the Kanagawa Prefectural Police Headquarters.ResultsIn 2013, the survey in Yokohama City showed large differences in age distribution and cause of death between examined and attended deaths. In 2014, home deaths accounted for 15.7% of all deaths in the prefecture, whereas the overall proportion of attended deaths at home was 6.9%.ConclusionsWe should utilize the rate of pure “attended deaths at home” for objective outcome indicator.

“…We did not collect diagnostic codes because it is said that diagnostic codes in NDB do not reflect the actual patient's diagnosis due to insurance claims needs. 32 To address the uncertainty/inaccuracy of diagnostic codes in NDB, some studies have combined diagnostic codes with other reliable examination or treatment codes (eg, breast cancer code and cancer treatment codes (surgery/ chemotherapy/medication/radiation procedure)). 33 However, in the psychiatric field, diagnostic codes in NDB are usually based on medical doctors' own judgement, and there are no other reliable examination or treatment codes to determine specific disorders.…”

ObjectivesTo clarify the dissemination status of cognitive behavioural therapy (CBT) in Japan under the national health insurance scheme.DesignRetrospective observational study.SettingNational Database of Health Insurance Claims and Specific Health Checkups of Japan.ParticipantsPatients who received CBT under the national health insurance scheme from fiscal years (FY) 2010 to 2015.Primary and secondary outcome measuresWe estimated the change rate and the standardised claim ratio (SCR) for the number of patients receiving CBT and analysed the association between the CBT status and several regional factors.ResultsWe found that (a) a total of 60 304 patients received CBT during the study period; (b) the number of patients receiving CBT was highest in the first year (−1.8% from FY2010 to FY2015); (c) the number of patients who received CBT per 100 000 population decreased (or remained at zero) in most prefectures (32 out of 47); (d) there was a maximum 424.7-fold difference between prefectures in the standardised claim ratio for CBT and (e) the number of registered CBT institutions was significantly associated with the number of patients who received CBT.ConclusionsThe provision of CBT did not increase in the first 6 years (FY2010–2015) after its coverage in Japan’s national health insurance scheme. Further studies including a questionnaire survey of registered CBT institutions are required to get more detailed information on the dissemination of CBT in Japan.

“…The NDB was established by the Japanese government to monitor health care claims, costs, evaluate medical utilization, and conduct clinical research and is the only claims database that can be used to assess real-world health care in a country where 100% of its older population is covered by a universal health care system. 17,18 The NDB database contains data for all diagnoses and all medical practices covered by universal health insurance, but specific items that can be extracted for each research purpose are limited. For this study, only data related to 3 indicators were available, and the available data did not include laboratory values, such as estimated glomerular filtration rate (eGFR) or hemoglobin levels.…”
