Pediatric medication error reports in Korea adverse event reporting system database, 1989-2012: comparing with adult reports.

Children have dynamic process of maturation and substantial changes in growth and development which eventually make the drug safety profiles different from adults. Medication errors (MEs) in pediatrics are reported to occur three times more likely than adults. The aims of this study were to identify the characteristics of pediatric MEs in Korea at national level and help raise awareness of risks from the MEs in pediatrics. We conducted a descriptive analysis with the pediatric ME reports in Korea Adverse Event Reporting System (KAERS) database from 1989 to 2012 and 208 ME reports in pediatrics were found. Based on KAERS database, the proportion of reported pediatric ME in adverse drug event (ADE) reports was 2.73 times (95% CI, 2.35-3.17) higher than that of adult ME. In 208 ME reports, we found a total of 236 ME-related terms within 19 types of MEs. The most common type of MEs was "accidental overdose" (n=58, 24.6%), followed by "drug maladministration" (n=50, 21.2%) and "medication error" (n=41, 17.4%). After the narratives of ME reports were reviewed, we noticed that most of them did no harm to patients, but some cases were needed for medical treatment. Our data suggest that MEs in pediatrics are not negligible in Korea. We expect that this study would increase the awareness of the problem in pediatric MEs and induce the need for further development of an effective national ME preventing system in Korea.

New initiatives for pharmacovigilance in South Korea: introducing the Korea Institute of Drug Safety and Risk Management (KIDS).

PURPOSE: Pharmacovigilance plays a vital role in ensuring that patients receive appropriate medical products that are safe and effective. This paper aims to describe the history of pharmacovigilance in Korea and introduce the establishment and goal of the KIDS. METHODS: In Korea, the adverse drug reactions (ADR) reporting system was launched in 1988 by the Korea Ministry of Food and Drug Safety (MFDS) and spontaneous ADR reports have been collected from health care professionals and the general public. Although the ADR reporting system has begun, the reporting rate was very low in the first 10 years, and safety actions were done passively in response to the US Food and Drug Administration (FDA) or European Medicines Agency (EMA)'s safety alert and communications. RESULTS: Therefore, the Korea Institute of Drug Safety and Risk Management (KIDS) was established in April 2012 as a new initiative for pharmacovigilance. CONCLUSIONS: The KIDS will continue to contribute to the improvement of Korean pharmacovigilance by collecting, managing, and analyzing consumer-centered drug safety information.

Korean Pharmacovigilance System Based on EHR-CDM.

An electronic health record (EHR) contains various clinical information for pharmacovigilance studies, but they remain difficult to use. From 2016 to 2018, the ministry of food and drug safety and Korea institute of drug safety & risk management (KIDS) converted the EHRs of more than 9 million patients to a MOA common data model (CDM). KIDS developed the Medical record observation and assessment for drug safety network (MOA-Net), a web portal site to build a network between CDM data partners. Through MOA-Net, hospitals participated in pharmacovigilance studies and confirmed the usability and adequacy of the CDM.

Comparison of drug-induced sleep endoscopy and lateral cephalometry in obstructive sleep apnea.

OBJECTIVES/HYPOTHESIS: To evaluate the association between findings from drug-induced sleep endoscopy (DISE) and lateral cephalometry in obstructive sleep apnea (OSA) STUDY DESIGN: Cross-sectional. METHODS: This was a consecutive series of subjects with OSA who underwent DISE and lateral cephalometry. DISE findings were characterized according to the region/degree of obstruction as well as the VOTE classification (velum, oropharyngeal lateral walls, tongue, and epiglottis). The primary measurements from lateral cephalometry images were sella-nasion-point A angle, sella-nasion-point B angle, distance from the posterior nasal spine-tip of palate, posterior airway space, and mandibular plane to hyoid (MPH) distance, although additional airway measurements were taken. Descriptive statistics summarized DISE and lateral cephalometry findings, and χ(2) and t tests examined potential associations between their findings. RESULTS: Among the 55 subjects, most demonstrated velum-related obstruction, although obstruction related to other structures was also common. Lateral cephalometry findings were within population norms with the exception of an increased MPH and decreased airway 4 and airway 5 measurements. There was little association between DISE and lateral cephalometry findings, although significant associations were identified between tongue-related obstruction and airway measurements posterior to the tongue base. CONCLUSIONS: DISE and lateral cephalometry are largely distinct airway evaluation techniques in OSA. The use of these techniques remains complementary.
