Abstract

The Korea National Disability Registration System (KNDRS) was established in 1989 to provide social welfare benefits based on predefined criteria for disability registration and an objective medical assessment using a disability grading system. Disability registration requires (1) a medical examination by a qualified specialist physician and (2) a medical advisory meeting to review the degree of disability. Medical institutions and specialists for the diagnosis of disabilities are legally stipulated, and medical records for a specified period are required to support the diagnosis. The number of disability types has gradually expanded, and 15 disability types have been legally defined. As of 2021, 2.645 million people were registered as disabled, accounting for approximately 5.1% of the total population. Among the 15 disability types, disabilities of the extremities account for the largest proportion (45.1%). Previous studies have investigated the epidemiology of disabilities using data from the KNDRS, combined predominantly with data from the National Health Insurance Research Database (NHIRD). Korea has a mandatory public health insurance system that covers the entire Korean population, and the National Health Insurance Services manages all eligibility information, including disability types and severity ratings. In short, the KNDRS-NHIRD is a significant data resource for research on the epidemiology of disabilities.

한국에서는 장애의 유형과 장애 유형별 장애정도를 장애인 복지법에서 규정하고 있다. 우리는 한국의 장애등록제도의 역사와 장애등록절차 그리고 장애유형별 통계 현황에 대해서 다루고자 한다.

Key Message
In Korea, the types and severity levels of disabilities are legally defined by the Korea National Disability Registration System (KNDRS). We address the history of the KNDRS, disability registration procedures, and current statistics.

Abstract

OBJECTIVES
Studies on the association between disabilities and tuberculosis (TB) are scarce. We aimed to assess the risk of active TB disease among people with disabilities.

METHODS

We conducted a nationwide serial cross-sectional study using national registry linkage databases from 2008 to 2017. The crude and age-standardized and sex-standardized incidence rates of TB were analyzed for each year according to the presence, type, and severity of disabilities. The crude incidence rate and odds of developing TB disease were examined with a multivariable logistic regression model using data from 2017.

RESULTS

The overall incidence of active TB decreased between 2008 and 2017. The age- and sex-standardized incidence rates of TB disease among people with disabilities were significantly higher than among those without disabilities throughout all observed years (p<0.001). As of 2017, the population with disabilities had a higher crude incidence rate of active TB disease than that without disabilities (119.9/100,000 vs. 48.5/100,000 person-years, p<0.001), regardless of sex, income level, and place of residence. Compared to those without disabilities, those with disabilities had higher odds of active TB (adjusted odds ratio [aOR], 1.19; 95% confidence interval [CI], 1.15 to 1.24). Individuals with mental disabilities (aOR, 1.51; 95% CI, 1.24 to1.84) had the highest odds of active TB incidence, followed by those with developmental disabilities (aOR, 1.30; 95% CI, 1.09 to 1.55).

CONCLUSIONS

People with disabilities are at a greater risk of developing TB disease. Active screening and care for TB cases would be beneficial for people with disabilities.

Summary

Korean summary
장애가 있는 사람은 이차적 건강 문제가 발생할 가능성이 더 높고 그들의 건강결정요인은 결핵 발생 위험 요인과 겹친다. 장애인은 비장애인에 비해 연령과 성별에 관계없이 활동성 결핵 발병률이 현저히 높았으며, 장애 유형 중 정신장애와 발달장애가 결핵에 더 취약한 것으로 나타났다. 장애인과 같이 결핵 감염 위험이 있는 취약계층을 파악하고 이들에게 결핵진단 및 항결핵치료의 어려움을 극복할 수 있도록 다학제적 지원을 제공하는 것이 중요하겠다.

Key Message
People with disabilities are more likely to develop secondary health conditions and their social determinants of health overlap with the risk factors for developing TB disease. We found that compared to people without disabilities, a markedly higher incidence of active TB disease among people with disabilities regardless of age and sex, and mental and developmental disabilities among types of disability were more prone to TB disease. It is critical to identify the vulnerable populations, such as people with disabilities, at risk of developing TB infection and provide them with multidisciplinary support to overcome any barriers during TB diagnosis and anti-TB treatment.
