Validation of recorded data is a prerequisite for studies that utilize administrative databases. The present study evaluated the validity diagnoses and procedure records in Japanese Diagnosis Procedure Combination (DPC) data, along with laboratory test results newly-introduced Standardized Structured Medical Record Information Exchange (SS-MIX) data.Between November 2015 February 2016, we conducted chart reviews 315 patients hospitalized between April 2014 March four middle-sized acute-care...
To investigate the temporal trend in national incidence of bronchiolitis hospitalizations, their characteristics, inpatient resource use, and hospital cost from 2000 through 2016.
Heart failure (HF) and atrial fibrillation (AF) are growing in prevalence worldwide. Few studies have assessed to what extent stage 1 hypertension the 2017 American College of Cardiology/American Association blood pressure (BP) guidelines is associated with incident HF AF.Analyses were conducted a nationwide health claims database collected JMDC Claims Database between 2005 2018 (n=2 196 437; mean age, 44.0±10.9 years; 58.4% men). No participants taking antihypertensive medication or had...
We reviewed the results of endovascular aneurysm repair in patients from Japanese Committee for Stentgraft Management registry to determine significance persistent type II endoleak (p-T2EL) and risk late adverse events, including sac enlargement.The prospectively captured medical records 17 099 <75 years age who underwent abdominal aortic 2006 2015 were reviewed. Patients divided into 2 groups (with or without p-T2EL) compared examine correlation between p-T2EL occurrence enlargement after...
To examine the incidence of vertebral osteomyelitis (VO) and clinical features VO focusing on risk factors for death using a Japanese nationwide administrative database.Retrospective observational study.Hospitals adopting Diagnosis Procedure Combination system during 2007-2010.We identified 7118 patients who were diagnosed with (International Classification Diseases, 10th Revision codes: A18.0, M46.4, M46.5, M46.8, M46.9, M48.9 M49.3, checked detailed diagnoses in each case all other codes...
Objectives: The role of intraaortic balloon pumping combined with venoarterial extracorporeal membrane oxygenation in cardiogenic shock patients remains unknown. This study investigated the effect on reducing mortality patients. Design: Retrospective cohort study. Setting: Japanese Diagnosis Procedure Combination national inpatient database. Patients: Cardiogenic adult receiving peripheral at admission were identified database from July 1, 2010, to March 31, 2013. Interventions: None....
Abstract Background High morbidity and mortality rates after pancreaticoduodenectomy (PD) have led to concentration of this surgery in high-volume centres, with improved outcomes. The extent which better outcomes might be apparent a healthcare system where the rate is already low unclear. Methods Japanese Diagnosis Procedure Combination database was used identify patients undergoing PD between 2007 2010. Patient data included age, sex, co-morbidities at admission, type hospital, PD, year...
We aimed to examine the concurrent effects of timing and intensity rehabilitation on improving activities daily living (ADL) among patients with ischemic stroke.Using Japanese Diagnosis Procedure Combination inpatient database, we retrospectively analyzed consecutive stroke at admission who received (n=100 719) from April 2012 March 2014. Early was defined as that starting within 3 days after admission. The average per day calculated total units during hospitalization divided by length...
In Brief Objective: a large nationwide administrative database of hospitalized patients, we investigated postoperative outcomes after laparoscopic or open distal gastrectomy in Japan. Background: The benefits gastrectomy, such as decreased length stay and morbidity, have typically been evaluated only with limited data on the basis small samples. Methods: Using Japanese Diagnosis Procedure Combination Database, identified 9388 patients who were preoperatively diagnosed stage I II gastric...
The mortality rate of severely ill patients treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO) remains unknown because differences in patient background, clinical settings, and sample sizes between studies. We determined the in-hospital VA-ECMO proportion weaned from using a national inpatient database Japan. Patients aged ≥19 years who received during hospitalization for cardiogenic shock, pulmonary embolism, hypothermia, poisoning, or trauma 1 July 2010 31 March 2013...
Japan established an original case-mix classification system in 2002, so called Diagnosis Procedure Combination (DPC). The main purposes of introducing the DPC are providing transparency hospital performance as well implementing electronic billing system. Researchers can utilize data to identify, track, and analyze national trends health care utilization, access, quality, outcomes, costs. unique advantage is inclusion detailed process several clinical data, which be applied academic studies...
<h3>Objective</h3> A catecholamine-mediated mechanism has been implicated in the pathogenesis of Takotsubo cardiomyopathy (TC). However, impact β-blockers acute-phase management TC remains uncertain. This study aimed to examine whether early β-blocker use was associated with lower in-hospital mortality. <h3>Methods</h3> a retrospective cohort using Diagnosis Procedure Combination nationwide inpatient database Japan. Patients aged ≥20 years who were admitted acute-care hospitals between 2010...
