Relationship Between Patients' "Sense of Participation" in Healthcare and Their Satisfaction A Survey of 5 Hospitals.

Patient participation is considered important for the safety and quality of care. The patient's perception of actually being able to participate in healthcare, namely, the sense of participation, may influence patient satisfaction (PS). This study aimed to quantitatively determine the relationship between sense of participation to healthcare and PS.

Cost of illness for colorectal cancer in Japan - a time trend and future projections (1996-2035) based on governmental statistics.

Background: In Japan, the crude mortality rate of colorectal cancer is the second highest among men and highest among women by site. We aimed to calculate the social burden of colorectal cancer using the cost of illness (COI) method and identify the main factors that drove changes in the COI.

Methods: From 1996 to 2020, the COI was estimated by summing direct, morbidity, and mortality costs.

Involvement of methodological experts and the quality of clinical practice guidelines: a critical appraisal of clinical practice guidelines and a questionnaire survey of the development groups in Japan.

Objective: To evaluate whether the involvement of methodological experts improves the quality of clinical practice guidelines (CPGs) after adjusting for other factors.

Setting: The quality of Japanese CPGs published in 2011-2019 was assessed using the Appraisal of Guidelines, Research, and Evaluation (AGREE) II instrument. A questionnaire survey targeting CPG development groups was conducted through postal mail.

Development and usability of a hospital standardized ADL ratio (HSAR) for elderly patients with cerebral infarction: a retrospective observational study using administrative claim data from 2012 to 2019 in Japan.

Background: Maintenance of activities of daily living (ADL) during acute hospitalization is an important treatment goal, especially for elderly inpatients with diseases that often leave disabilities, such as cerebral infarction. However, studies assessing risk-adjusted ADL changes are limited. In this study, we developed and calculated a hospital standardized ADL ratio (HSAR) using Japanese administrative claims data to measure the quality of hospitalization care for patients with cerebral infarction.

Cost of illness in a super-aged society-comparison of breast, lung, and prostate cancer in Japan.

Background: Aging increases the disease burden because of an increase in disease prevalence and mortality among older individuals. This could influence the perception of the social burden of different diseases and treatment prioritization within national healthcare services. Cancer is a disease with a high disease burden in Japan; however, the age-specific frequency and age-specific mortality rates differ according to site.

Evaluating the Hospital Standardized Home-Transition Ratios for Cerebral Infarction in Japan: A Retrospective Observational Study from 2016 through 2020.

Discharge to home is considered appropriate as a treatment goal for diseases that often leave disabilities such as cerebral infarction. Previous studies showed differences in risk-adjusted in-hospital mortality and readmission rates; however, studies assessing the rate of hospital-to-home transition are limited. We developed and calculated the hospital standardized home-transition ratio (HSHR) using Japanese administrative claims data from 2016-2020 to measure the quality of in-hospital care for cerebral infarction.

Hospital-level characteristics of the standardised mortality ratio for ischemic heart disease: a retrospective observational study using Japanese administrative claim data from 2012 to 2019.

Background: Ischemic heart disease (IHD) is one of the leading causes of mortality worldwide and imposes a heavy burden on patients. Previous studies have indicated that the optimal care for IHD during hospitalisation may reduce the risk of in-hospital mortality. The standardised mortality ratio (SMR) is an indicator for assessing the risk-adjusted in-hospital mortality ratio based on case-mix.

Trends in the development process of clinical practice guidelines: a questionnaire survey for the guideline development groups in Japan.

Background: Clinical practice guidelines (CPGs) are representative methods for promoting healthcare standardization and improving its quality. Previous studies on the CPG (published by 2006) development process in Japan reported that the involvement of experts and patients, efficient evidence collection and appraisal, and paucity of evidence on Japanese patients should be improved for the efficient CPG development. This study aimed to clarify the trends of CPG development process in Japan, focusing on the involvement of experts and patients, efficient evidence collection and appraisal, and paucity of Japanese evidence.

Characteristics and Trends of the Hospital Standardized Readmission Ratios for Pneumonia: A Retrospective Observational Study Using Japanese Administrative Claims Data from 2010 to 2018.

Previous studies indicated that optimal care for pneumonia during hospitalization might reduce the risk of in-hospital mortality and subsequent readmission. This study was a retrospective observational study using Japanese administrative claims data from April 2010 to March 2019. We analyzed data from 167,120 inpatients with pneumonia ≥15 years old in the benchmarking project managed by All Japan Hospital Association.

An Isolable and Bench-Stable Epoxidizing Reagent Based on Triazine: Triazox.

A new triazine-based oxidizing reagent, 2-hydroperoxy-4,6-diphenyl-1,3,5-triazine (Triazox), has been developed. The reagent can be synthesized from inexpensive starting materials and is a bench-stable solid that is isolable in pure form. Epoxidation of alkenes possessing acid-sensitive functionalities using Triazox proceeded in good to excellent yields.
