Prevalence and Incidence of Neuromyelitis Optica Spectrum Disorder in Korea: Population Based Study.

Background: Although neuromyelitis optica spectrum disorder (NMOSD) is known to be a rare disease, its prevalence and incidence have not yet been studied in Korea. We performed a population-based study to examine the prevalence and incidence of NMOSD in Korea using data from the Korean National Health Insurance (NHI) claims database.

Methods: Data from 2013 to 2017 were obtained, with a washout period set as 2013 and 2014.

Healthcare utilization among children and young people with life-limiting conditions: Exploring palliative care needs using National Health Insurance claims data.

Paediatric palliative care (PPC) is regarded as standard care for children and young people (CYP) with life-limiting conditions (LLCs). There is a lack of knowledge about the rate of CYP with LLCs, hampering the development of PPC. This retrospective study aimed to examine population-based statistics of South Korean CYP with LLCs and the pattern of healthcare use and costs in their last year of life, analysing the National Health Insurance Service claims database for the period 2013-2015.

Parkinson's Disease as Risk Factor in Osteoporosis and Osteoporotic Vertebral Fracture : Prevalence Study Using National Inpatient Sample Database in Korea.

Objective: To determine the prevalence of osteoporosis (OP) and osteoporotic vertebral fracture (OVF) in people with Parkinson's disease (PD) in Korea and its association with socioeconomic status.

Methods: Using Health Insurance Review and Assessment Service-National Inpatient Sample (HIRA-NIS) data from 2009 to 2013, we estimated the annual prevalence of PD, OP, and OVF and investigated its association with socioeconomic status using data from National Health Insurance (NHI) beneficiaries and Medical Aid (MA) recipients. This study was supported by research funding from Korean Society for Bone and Mineral Research 2015.

Socioeconomic status can affect pregnancy outcomes and complications, even with a universal healthcare system.

Korea has been adopting a universal healthcare system. All Korean citizens must be enrolled National Health Insurance (NHI) or be recipient of Medical Aid (MA).

Differences in pregnancy outcomes, prenatal care utilization, and maternal complications between teenagers and adult women in Korea: A nationwide epidemiological study.

Teenage mothers are at high risk for maternal and neonatal complications. This study aimed to evaluate the socioeconomic circumstances of teenage pregnancy, and determine whether these increased risks remained after adjustment for socioeconomic circumstances in Korea.

Methods: We attempted to estimate the incidence and prevalence rates of MG using the Korean National Health Insurance claims database for 2010 to 2013.

Pregnancy, prenatal care, and delivery of mothers with disabilities in Korea.
