Dementia and frailty often accompany one another in older age, requiring complex care resources. Available projections provide little information on their joint impact future health-care need from different segments of society the associated costs. Using a newly developed microsimulation model, we forecast this situation Japan as its population ages decreases size.In modelling study, built model that simulates an individual's status transition across 11 chronic diseases (including diabetes,...
This paper reviews the history of storage systems. The first section begins with era early mechanical calculators and following four sections review historically major devices such as magnetic tapes, disks, optical devices, solid-state devices. final two focus on recent system technologies networking cloud-based storage.
To evaluate condition-specific antibiotic prescription rates and the appropriateness of use in outpatient settings Japan.Using Japan's national administrative claims database, all visits with infectious disease diagnoses were linked to reimbursed oral prescriptions. Prescription stratified by age, sex, prefecture, category determined for each diagnosis. The proportions any first-line prescriptions calculated diagnosis.Of 659 million between April 2012 March 2015, antibiotics prescribed 266...
ABSTRACT Objectives Antibiotic prescription trends in dentistry Japan remain underexplored. This study aimed to describe these and evaluate the impact of national antimicrobial stewardship program launched 2016. Methods Using Japan's administrative claims database from fiscal year (FY) 2015 FY 2020, this cross‐sectional comprehensively analyzed antibiotic by dentists. Prescription rates were computed per 1000 inhabitants yearly standardized population. Changes evaluated using Poisson...
Abstract Background The World Health Organization aims to eliminate hepatitis C virus (HCV) infections by 2030. Interferon-free direct-acting antiviral (DAA) therapy, available in Japan since 2014, has demonstrated high cure rates and reduced C-related hepatocellular carcinoma (HCC). However, DAA therapeutic efficacy on a national scale remains underexplored. In this study, we investigated trends HCV prevalence complications, including liver cancer, during the era of interferon-free DAAs,...
Research on the effectiveness of Japan's national action plan antimicrobial resistance, including among individuals with HIV, remains scarce. To evaluate impact policies antibiotic prescription practices. Outpatient oral data from 2012 to 2020 were extracted a claims database comprising >98% Japanese population. Prescription rates stratified according class, diagnosis and HIV status. An interrupted time-series analysis was performed assess plan. average 129,989,400 prescriptions issued...
The COVID-19 pandemic has raised concerns about continuity of care for chronic diseases such as diabetes, hypertension, and dyslipidemia. Although studies have documented declines in healthcare utilization, few assessed individual-level patterns treatment interruption. We conducted a retrospective cohort analysis using administrative claims data (2018-2021) from Prefecture, Japan. Eligible patients were diagnosed with prescribed medications diabetes mellitus, or dyslipidemia January 2019...
The COVID-19 pandemic has forced people to change many behaviours, including physical distancing, hygiene measures and lifestyles. This study aimed evaluate the indirect impact of on incidence non-COVID-19 infections medical care costs/visits using health insurance claims.This was an observational patient-based administrative claims covering approximately 800,000 insured persons their dependents in Mie Prefecture Japan.This identified infectious disease incidences, number outpatient visits...
Telehealth using telephones or online communication is being promoted as a policy initiative in several countries. However, there lack of research on telehealth utilization country such Japan that offers free access to medical care and regulates provision-particularly with respect COVID-19.The present study aimed clarify utilization, the characteristics patients institutions telehealth, changes order support formulation strategies for provision.Using administrative claim database National...
Background: Driven by the rapid aging of population, Japan introduced public long-term care insurance to reinforce healthcare services for elderly in 2000. Precisely predicting future demand helps authorities plan and manage their resources citizens prevent health status deterioration.
Data intensive applications such as MapReduce can have large performance degradation from the effects of I/O interference when multiple processes access same resources simultaneously, particularly in case disks. It is necessary to understand this effect order improve resource allocation and utilization for these applications. In paper, we propose a model predicting impact on application performance. Our takes basic parameters workload hardware environment, knowledge behavior predict how...
Flash SSDs are being incorporated in many enterprise storage platforms recently. However, the characteristics of flash SSD quite different from that hard disk. The IO strategies existing systems should be carefully evaluated. This paper provides an evaluation on flash-based transaction processing system. Two file systems, traditional in-place update-based system and log-structured system, selected as representative two write strategies. Usually, is believed to play better SSDs. Our...
Understanding the spread of diseases and use medicines is practical importance for various organizations, such as medical providers, payers, national governments. This study aims to detect change in prescription trends identify its cause through an analysis Medical Insurance Claims (MICs), which comprise specifications fees charged health insurers. Our approach two-fold. (1) We propose a latent variable model that simulates medication behavior physicians accurately reproduce monthly time...
Intra-query parallelism is a key for database software to offer acceptable responsiveness data-intensive queries. Many researchers have studied how achieve greater execution Partitioning representative approach, which divides query into multiple sub-tasks and executes them in parallel. However, given new query, optimal division not necessarily obvious. Database utilizes heuristic rules or statistical information decide divide the before execution. As yet another approach parallelism, this...
A geo-referenced time series database represents the data generated by a set of fixed locations (or items) observing particular phenomenon over time. Useful information that can facilitate users to achieve socio-economic development lies hidden in this data. This paper introduces novel model Fuzzy Geo-referenced Periodic-Frequent Patterns (FGPFPs) may exist these databases. An FGPFP frequently occurring neighboring items observed at regular intervals database. For example, an traffic...
A 47-year-old right-handed female became aware of proximal ache and muscle weakness in the right shoulder elbow 1997. Atrophy biceps was recognized deltoid, triceps, supraspinatus, infraspinatus muscles were weak. The Morley test elevated arm stress positive. Neurolysis brachial plexus anterior scalenectomy performed via a supraclavicular approach. An abnormal fibromuscular band identified passing between upper middle trunks constricting trunk. Another scalene anomaly found C-5 C-6 nerve...
