An increasing number of studies are using healthcare claims databases to assess healthcare intervention utilization patterns or outcomes in real-world clinical settings. However, methodological issues affecting study design or data analysis can make conducting and reporting these types of studies difficult. This review presents an overview of the types of information contained in claims data, describes some advantages and limitations of using claims data for research purposes, and outlines steps

The change of health insurance coverage policy substantially influenced OACs prescription pattern in whole Korean region. But the impact has been significantly different among regions and age groups, which provides the evidence for developing standard clinical practice guideline on OACs use.

BACKGROUND: There is increasing concern that the effects of the COVID-19 pandemic will result in excess suicides by increasing known risk factors, such as suicide attempts. However, evidence on the long-term impacts of COVID-19 on suicide attempts is lacking. We aimed to assess the short- and long-term effects of the COVID-19 pandemic on patients with suicide attempts in emergency departments (EDs) and to evaluate age- and sex-specific differences. METHOD: We conducted nationwide cross-sectional

The long-term outcome of first-line moderate-intensity statin with ezetimibe combination therapy for secondary prevention after percutaneous coronary intervention in patients with acute coronary syndrome (ACS) compared to high-intensity statin monotherapy remains elusive. The objective of this study was to compare the effectiveness of moderate-intensity statin and ezetimibe combination therapy with high-intensity statin monotherapy. We conducted a nationwide, population-based, retrospective, coh

We propose Object Cluster Registration (OCR) using Geometric Spatial Affordance Graph (GSAG) to support user interaction with multiple objects in a shared space generated from two dissimilar rooms. Previous research on generating a shared virtual space from dissimilar real spaces has only reflected the information of individual objects and aimed at maximizing the area of the shared space. This led to limited interactions relying on the singular affordances of objects, neglecting to consider the

BACKGROUND: Depression, the leading cause of nonfatal disease burden, has a strong correlation with suicide and affects approximately 7% of the general elderly population. Adverse drug reactions in older patients are particularly important because of reduced drug metabolism, polypharmacy, drug-drug interactions, and drug-disease interactions. Fluoxetine is the first representative selective serotonin reuptake inhibitor but is associated with the possibility of hemorrhage based on its mechanism o

Background: Fluoroquinolones (FQs) are commonly used to treat urinary tract infections (UTIs), but some studies have suggested they may increase the risk of aortic aneurysm or dissection (AA/AD). However, no large-scale international study has thoroughly assessed this risk. Methods: A retrospective cohort study was conducted using a large, distributed network analysis across 14 databases from 5 countries (United States, South Korea, Japan, Taiwan, and Australia). The study included 13,588,837 pa

To enable remote Virtual Reality (VR) and Augmented Reality (AR) clients to collaborate as if they were in the same space during Mixed Reality (MR) telepresence, it is essential to overcome spatial heterogeneity and generate a unified shared collaborative environment by integrating remote spaces into a target host space. Especially when multiple remote users connect, a large shared space is necessary for people to maintain their personal space while collaborating, but the existing simple interse

BACKGROUND: In order to ensure safer use of non-vitamin K antagonist oral anticoagulants (NOACs), continuously detecting unexpected adverse drug reactions (ADRs) after market approval is necessary. METHODS: We performed disproportionality analysis to evaluate association between ADRs and NOACs including apixaban, dabigatran, and rivaroxaban using data from the Korea Institute of Drug Safety and Risk Management-Korea Adverse Event Reporting System database (KIDS-KD) between 2012 and 2016.
