RESUMO
BACKGROUND: Little is known about disparities in diagnosis and treatment among colorectal cancer (CRC) patients with and without disabilities. AIM: To investigate the patterns of diagnosis, treatment, and survival for people with and without disabilities who had CRC. METHODS: We performed a retrospective analysis using the Korean National Health Insurance Service database, disability registration data, and Korean Central Cancer Registry data. The analysis included 21449 patients with disabilities who were diagnosed with CRC and 86492 control patients diagnosed with CRC. RESULTS: The overall distribution of CRC stage was not affected by disability status. Subjects with disabilities were less likely than those without disabilities to undergo surgery [adjusted odds ratio (aOR): 0.85; 95% confidence interval (95%CI): 0.82-0.88], chemotherapy (aOR: 0.84; 95%CI: 0.81-0.87), or radiotherapy (aOR: 0.90; 95%CI: 0.84-0.95). The rate of no treatment was higher in patients with disabilities than in those without disabilities (aOR: 1.48; 95%CI: 1.41-1.55). The overall mortality rate was higher in patients with disabilities [adjusted hazard ratio (aHR): 1.24; 95%CI: 1.22-1.28], particularly severe disabilities (aHR: 1.57; 95%CI: 1.51-1.63), than in those without disabilities. CONCLUSION: Patients with severe disabilities tended to have a late or unknown diagnosis. Patients with CRC and disabilities had lower rates of treatment with almost all modalities compared with those without disabilities. During the follow-up period, the mortality rate was higher in patients with disabilities than in those without disabilities. The diagnosis and treatment of CRC need improvement in patients with disabilities.
RESUMO
BACKGROUND: Existing studies on chronic obstructive pulmonary disease (COPD) in Korea lack full population coverage, relying on small sample sizes. Therefore, this study aims to investigate the prevalence and mortality of COPD in the entire Korean population. METHODS: This serial cross-sectional study used national databases, linking the National Health Information Database (2008-2017) with Causes of Death Statistics. Identification of individuals with COPD used diagnostic codes (International Classification of Diseases-10: J41-J44) or a history of COPD-related hospitalisation, focusing on adults aged 40 and above. Prevalence and mortality rates, calculated for 2008-2017, encompassed both crude and age-standardised and sex-standardised measures. A multivariate Poisson regression model estimated the association between COPD and all-cause and cause-specific mortality, presenting incidence rate ratios (IRRs) and 95% CIs, using data from the year 2017. RESULTS: Age-adjusted COPD prevalence exhibited a notable increase from 2008 (7.9%) to 2017 (16.7%) in both sexes. The prevalences of diabetes mellitus, hypertension, dyslipidaemia, ischaemic heart disease, cancer, osteoporosis and tuberculosis were higher in the COPD group than in the group without COPD (p for all <0.001). The incidence of stroke and myocardial infarction (p for all <0.001) and overall mortality were higher in the COPD group (adjusted IRR 1.23, 95% CI 1.22 to 1.24, p<0.001). In particular, incidence rate and risk of mortality due to lung cancer were higher than that of those without COPD compared with other cancer types (adjusted IRR 2.51, 95% CI 2.42 to 2.60, p<0.001). It was significantly higher the incidence rate and risk of mortality among group with COPD than those without COPD in lower respiratory disease (adjusted IRR 16.62, 95% CI 15.07 to 18.33, p<0.001), asthma (adjusted IRR 6.41, 95% CI 5.47 to 7.51, p<0.001) and bronchiectasis (adjusted IRR 11.77, 95% CI 7.59 to 18.26, p<0.001), respectively. DISCUSSION: Our study showed that the prevalence of COPD is gradually increasing from 9.2% in 2009 to 16.7% in 2018. Furthermore, in overall (all-cause) mortality, it was significantly higher in group with COPD than in group without COPD. The mortality rate of group with COPD was much higher than the overall mortality rate but is gradually decreasing.

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.

PURPOSE: Although obesity is an important risk factor for cancer incidence, the effect of body mass index (BMI) on health-related quality of life (HRQoL) after cancer treatment remains unknown. This population-based cross-sectional study assessed different levels of BMI as an important factor associated with impaired HRQoL in long-term cancer survivors. METHODS: The study enrolled 1104 cancer survivors from the fourth to seventh Korea National Health and Nutrition Examination Surveys (KNHANES 2007-2018) who were alive at least 5 years after their cancer diagnoses. The BMI was classified into four categories: < 20 (underweight), 20-22.9 (healthy weight), 23-24.9 (overweight), and ≥ 25 kg/m2 (obese). Impaired HRQoL was defined as the lowest quartile of European Quality of Life 5-Dimensions (EQ-5D) questionnaire scores. RESULTS: Cancer survivors who were underweight or obese were more likely to report health problems on each dimension of the EQ-5D compared to the other BMI groups. In multivariate logistic regression analysis, the two extreme BMI categories were significantly associated with impaired HRQoL (BMI < 20 kg/m2: odds ratio [OR] = 1.73, 95% confidence interval [CI] = 1.08-2.86; BMI ≥ 25 kg/m2: OR = 2.14, 95% CI = 1.41-3.25; P trend = 0.049), especially in the gastrointestinal cancer group (P heterogeneity = 0.007). Moreover, the association between underweight/obese and impaired HRQoL showed a significant sex difference (P heterogeneity = 0.019). CONCLUSIONS: The results of this study suggest that deviations from normal BMI, such as being underweight or obese, are negatively associated with HRQoL in long-term cancer survivors; to some extent, this may depend on cancer type and sex. IMPLICATIONS FOR CANCER SURVIVORS: Reaching or maintaining a healthy weight should be emphasized for cancer survivors as a long-term goal even after cancer treatment.

We aimed to evaluate the impacts of disability on the diagnosis, treatment, and prognosis of bile duct cancer (BDC) according to the severity and type of disability. Patients diagnosed with BDC were selected from an age- and sex-matched population (1:3 ratio) with or without disabilities from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claims database. The cohort included 15,065 patients with BDC, with a significantly lower rate in those with severe disabilities than in people without or with mild disabilities (110.6 vs. 136.5 vs. 147.6 per 105 persons, respectively). People with severe disabilities were diagnosed with BDC at an earlier age but were less likely to undergo surgery (adjusted odds ratio (aOR) = 0.52, 95% confidence interval (CI): 0.45-0.61) or chemotherapy (aOR = 0.76, 95% CI: 0.61-0.95) compared to those without disabilities. This trend was more evident in patients with mental disabilities. The overall and cancer-specific mortality rates were higher in patients (especially women) with disabilities than in those without. There needs systemic approach to ensure equal access to quality cancer care for people with disabilities.

Objective: Appendicitis is usually diagnosed based on a reliable set of signs and symptoms, and can be effectively treated with surgery, with low morbidity and mortality rates. However, appendicitis is often overlooked in vulnerable populations, including people with disabilities. This study compared 10-year trends of complicated appendicitis between South Koreans with a disability, according to disability severity and type, and those without disabilities. Methods: To identify cases of appendicitis, we used the DRG codes in the National Health Information Database of South Korea. Patients with appendicitis were classified in terms of severity based on the DRG codes. Age-standardized incidence rates were calculated for each year during 2008-2017 according to the presence, type, and severity of the disability. Factors associated with complicated appendicitis were examined by multivariate logistic regression using the most recent data (i.e., 2016-2017). Results: The incidence of complicated appendicitis was higher in people with disabilities, especially those with severe disabilities (26.9 vs. 11.6%). This difference was particularly marked when considering those with a severe disability (aOR = 1.868, 95% CI:1.511-2.309), internal organ problems (aOR = 10.000, 95% CI:5.365-18.638) or a mental disability (aOR = 2.779, 95% CI:1.563-4.939). Conclusions: The incidence of complicated appendicitis was higher in people with disability than in those without disability in all years. There was a substantial difference in the incidence of complicated appendicitis between the severe disability and non-disabled groups. Among the various disability types, the incidence of complicated appendicitis was highest for major internal organ problems, followed by intellectual or psychological disabilities. Our findings may be explained by barriers to healthcare access among people with disabilities, particularly those with a severe disability, internal organ problem, or mental disability.

BACKGROUND: This study was performed to examine the association between hospital volume and mortality in people with disability. METHODS: A retrospective cohort study was conducted using a data set linking the Korean National Health Service database, disability registration data, and Korean Central Cancer Registry data. Data was gathered from all patients undergoing the four major surgical procedures for cancer care during an 11-year period from 2003 to 2013. RESULTS: For all procedures, patients with disability were more likely to visit low-volume hospitals compared with those without disability. The 30-day mortality rate after each type of surgery at low-surgery-volume hospitals was higher in patients with disability; especially, the mortality rates after colectomy were 1.1% for patients without disabilities and 2.6% for patients severely disabilities. In univariate logistic regression analyses, patients with disability, especially those with severe or intellectual/psychological disabilities, were significantly less likely to undergo treatment at a high-volume hospital compared with patients without disability. In contrast, multiple logistic regression analysis indicated that patients with disability were significantly more likely to undergo gastrectomy (OR 3.76, 95% CI 1.64-8.58), colectomy (OR 3.08, 95% CI 1.46-6.48), and mastectomy (OR 3.92, 95% CI 1.25-12.33) at a high-volume hospital compared with patients without disability. CONCLUSION: Public health policies should focus on patients with disability to reduce health disparities and educate health care professionals, as well as the patients and their families, to alleviate negative perceptions about the need for equal diagnosis and treatment.

BACKGROUND: Disparities in cancer care have not been well documented for individuals with disability. OBJECTIVE: To investigate potential disparities in the diagnosis, treatment, and survival of prostate cancer (PC) patients according to disability status. METHODS: A retrospective cohort study using disability registration data linked to Korean National Health Insurance and national cancer registry data. Totals of 7924 prostate cancer cases among patients with disabilities (diagnosed between 2005 and 2013) and 34,188 PC patients without disability were included. RESULTS: While overall PC stage distribution at diagnosis was similar, unknown stage was more common in patients with severe disabilities compared to those without disabilities (18.1% vs. 16.2%, respectively). People with disabilities were less likely to undergo surgery (33.1% vs. 38.6%, respectively; adjusted odds ratio [aOR] 0.79, 95% confidence interval [CI] 0.74-0.84), and more likely to receive androgen deprivation therapy (ADT) (57.9% vs. 55%, respectively; aOR 1.10, 95% CI 1.04-1.16) compared to those without disabilities. This was more evident for people with severe brain/mental impairment (aORs 0.29 for surgery; 1.52 for ADT). Patients with disabilities had higher overall mortality (adjusted hazard ratio [aHR] 1.20; 95% CI, 1.15-1.25), but only slightly higher PC-specific mortality after adjustment for patient factors and treatment (aHR 1.11, 95% CI 1.04-1.18) than people without disability. CONCLUSIONS: PC patients with disabilities underwent less staging work-up and were more likely to receive ADT than surgical treatment. Overall mortality of PC patients with disabilities was greater than those of PC patients without disability, but PC-specific mortality was only slightly worse.

INTRODUCTION: Not much is known regarding the disparities in cancer care between women with and without disabilities. OBJECTIVES: The aim of this study was to investigate the potential disparities in the diagnosis, treatment, and survival of women with cervical cancer with and without disabilities. METHODS: We performed a retrospective cohort study and linked the National Disability Database, Korean Central Cancer Registry, and Korean National Health Insurance claims database. Charlson comorbidity index was used for adjusting the comorbidity. The study population comprised 3 185 women with disabilities (physical/brain, communication, mental, cardiopulmonary, and other impairment) who were diagnosed with cervical cancer and 13 582 age- and sex-matched women without disability who were diagnosed with cervical cancer for comparison. RESULTS: Distant metastatic stage (7.7% vs 3.7%) and unknown stage (16.1% vs 7.0%) were more common in cervical cancer women with grade 1 disabilities, compared with women without disabilities. Women with cervical cancer with disabilities were less likely to undergo surgery (adjusted odds ratio (aOR) 0.81, 95% confidence interval (CI) 0.73-0.90) or chemotherapy (aOR 0.86, 95% CI 0.77-0.97). Lower rate of surgery was more evident in patients with physical/brain impairment (aOR 0.46, 95% CI 0.37-0.58) and severe mental impairment (aOR 0.57, 95% CI 0.41-0.81). The overall mortality risk was also higher in patients with disabilities (adjusted hazard ratio (aHR) 1.36, 95% CI 1.25-1.48). CONCLUSION: Women with cervical cancer with disabilities, especially with severe disabilities, were diagnosed at later stages, received less treatment, and had higher mortality rates, compared with patients who lacked disabilities. Social support and policies, along with education for women with disabilities, their families, and healthcare professionals, are needed to improve these disparities.

GOAL: The goal of this study was to determine disparities in liver cancer surveillance among people with disabilities is the goal of this study. BACKGROUND: Using the linked administrative database in Korea, we sought to investigate (1) whether there are disparities in liver cancer surveillance according to degree and type of disability and (2) temporal trends in liver cancer surveillance among people with disabilities. MATERIALS AND METHODS: We linked national disability registration data with national cancer surveillance data. We analyzed age-standardized participation rates for each year during the 2006-2015 period according to presence, type, and severity of the disability. We also examined factors associated with liver cancer surveillance by multivariate logistic regression using the most current data (2014-2015). RESULTS: The age-adjusted and sex-adjusted surveillance rate for liver cancer in people with disabilities increased from 25.7% in 2006 to 49.6% in 2015; however, during the same period, surveillance rate among people without disabilities increased from 24.9% to 54.5%. As a result, disparities in surveillance for liver cancer increased over time. The surveillance participation rate among people with disabilities was 12% lower than among people without disabilities. Surveillance rates were markedly lower among people with severe disabilities [adjusted odds ratio (aOR)=0.71] and people with renal disease (aOR=0.43), brain injuries (aOR=0.60), ostomy problems (aOR=0.60), and intellectual disabilities (aOR=0.69). CONCLUSIONS: Despite the availability of a national liver cancer surveillance program, a marked disparity was found in liver cancer surveillance participation, especially among people with severe disabilities, renal disease, or brain-related or mental disabilities.

PURPOSE: The purpose of this study was to evaluate end-of-life resource utilization and costs for prostate cancer patients during the last year of life in Korea. MATERIALS AND METHODS: The study used the National Health Information Database (NHIS-2017-4-031) of the Korean National Health Insurance Service. Healthcare claim data for the years 2002 through 2015 were collected from the Korean National Health Insurance System. Among 83,173 prostate cancer patients, we enrolled 18,419 after excluding 1,082 who never claimed for the last year of life. RESULTS: From 2006 to 2015, there was a 3.2-fold increase the total number of prostate cancer decedents. The average cost of care during the last year of life increased over the 10-year period, from 14,420,000 Korean won to 20,300,000 Korean won, regardless of survival time. The cost of major treatments and medications, other than analgesics, was relatively high. Radiologic tests, opioids, pain control, and rehabilitation costs were relatively low. Multiple regression analysis identified age and living in rural area as negatively associated with prostate cancer care costs, whereas income level and a higher number of comorbidities were positively associated. CONCLUSIONS: Expenditure of prostate cancer care during the last year of life varied according to patient characteristics. Average costs increased every year. However, the results suggest underutilization of support services, likely due to lack of alternative accommodation for terminal prostate cancer patients. Further examination of patterns of utilization of healthcare resources will allow policymakers to take a better approach to reducing the burden of prostate cancer care.
RESUMO
INTRODUCTION: We investigated potential disparities in the diagnosis, treatment, and survival of gastric cancer (GC) patients with and without disabilities. METHODS: We linked Korean National Disability Registry data with the Korean National Health Insurance database and Korean Central Cancer Registry data. This study included a total of 16,849 people with disabilities and 58,872 age- and sex-matched control subjects in whom GC had been diagnosed. RESULTS: When compared to GC patients without disabilities, patients with disabilities tended to be diagnosed at a later stage (localized stage 53.7% vs 59.0% or stage unknown 10.7% vs 6.9%), especially those with severe disabilities (P < 0.001). This was more evident in patients with mental impairment (localized stage 41.7% and stage unknown 15.2%). In addition, not receiving treatment was more common in patients with disabilities than those without disabilities (29.3% vs 27.2%, P < 0.001), and this disparity was more evident in those with severe disabilities (35.4%) and in those with communication (36.9%) and mental (32.3%) impairment. Patients with disabilities were at slightly higher risk of overall mortality as well as GC-specific mortality compared to people without disabilities (adjusted hazard ratio [aHR] = 1.18, 95% confidence interval: 1.14-1.21 and aHR = 1.12, 95% confidence interval: 1.09-1.16, respectively), and these disparities were more pronounced in those with severe disabilities (aHR = 1.62 and 1.51, respectively). DISCUSSION: Patients with disabilities, especially severe disabilities, were diagnosed with GC at a later stage, received less staging evaluation and treatment, and their overall survival rate was slightly worse compared to those without disabilities.

We analyzed the patterns of diagnosis, treatment, and prognoses of acute myeloid leukemia (AML) patients with and without disabilities. The data were collected from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claim database. We built a cohort of 2 776 450 people with disabilities and a nondisabled cohort of 8 329 350 people who were selected at a ratio of 1:3 by matching age and sex. From this population, adult patients who were diagnosed with AML were analyzed. The number of patients with AML were 26.74 per 100 000 in people without disabilities and 20.39 per 100 000 in those with disabilities (P < .0001). The proportion of AML patients receiving chemotherapy and those of patients receiving transplants were significantly lower in the disabled population than that of nondisabled populations (71.2% vs 77.1%, P = .0031, and 17.5% vs 26.9%, P = .002). This trend was more pronounced in subgroups of communication disability and major internal organ disorder. The median survival was 10.8 months for patients with disabilities, which was significantly shorter than 17.1 months for those without a disability (P = .002). Individuals with disabilities have a low diagnosis rate of AML and undergo less active treatment, which results in inferior prognosis.

PURPOSE: Burnout in oncologists negatively impacts patient care and health care system, as it is associated with poor patient satisfaction, medical errors, leaving current practice, and/or early retirement. Because the quality of life of oncologists is influenced by various factors and ultimately affects the patient's treatment and medical system, we aimed to investigate burnout among oncologists and to identify factors affecting burnout. MATERIALS AND METHODS: A total of 130 oncologists recruited from 13 cancer centers participated in a nationwide survey. Professional Quality of Life scale used to evaluate burnout and multiple regression analysis was performed to identify factors affecting burnout. RESULTS: A total of 144 oncologists were invited, 134 (93.1%) responded, and 130 (90.2%) of those completed the survey. Burnout score of all participants was 49.9, and males was 48.8, females was 53.9, females score was higher than males. According to the hours worked per session, the average burnout score increased with the hours worked per session. Multiple regression analysis showed that influencing or predictive factors in burnout were sex and hours worked per session. CONCLUSION: To reduce burnout in oncologists, organization-directed interventions should be implemented to prevent work overload.

BACKGROUND: Health disparities among individuals with disabilities remain underrecognized. The objective of the current study was to investigate: 1) whether disparities exist in breast cancer screening rates among women with disabilities compared with women without disabilities; 2) whether breast cancer screening rates vary according to the type and severity of disabilities; and 3) trends in breast cancer screening disparities according to disability status over time. METHODS: Using national administrative databases concerning disability status and national cancer screening programs in Korea, age-standardized participation rates were calculated according to the type and severity of disabilities. RESULTS: The age-standardized rate for breast cancer screening in individuals with disabilities increased from 30.2% in 2006 to 53.7% in 2015 (change of +23.5%), whereas that among those without a disability increased from 29.3% to 60.1% (change of +30.8%). In general, disability was associated with slightly lower breast cancer screening rates (adjusted odds ratio [aOR], 0.824; 95% CI, 0.820-0.828). However, screening rates were especially low in women with severe disabilities (aOR, 0.465; 95% CI, 0.461-0.469) and among women with autism (aOR, 0.235; 95% CI, 0.143-0.388), renal failure (aOR, 0.342; 95% CI, 0.337-0.348), brain injury (aOR, 0.349; 95% CI, 0.346-0.352), intellectual disabilities (aOR, 0.403; 95% CI, 0.397-0.410), mental disorders (aOR, 0.494; 95% CI, 0.488-0.501), or ostomies (aOR, 0.529; 95% CI, 0.512-0.546). CONCLUSIONS: Even without a cost barrier, significant disparities were found in breast cancer screening participation, especially in women with severe disabilities and brain-related and/or mental disabilities. Policy efforts, such as ensuring the accessibility of information and equipment, transportation support, and access to a usual source of care, should be made to decrease this disparity.

PURPOSE: This study aimed to determine whether the diagnosis, treatment approach, and prognosis of multiple myeloma (MM) vary according to the presence and type of disability. Materials and Methods: Demographic, socioeconomic, and medical data were obtained from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claims database. An age- and sex-matched cohort was established using a 1:3 ratio constituted with 2,776,450 people with disabilities and 8,329,350 people without disabilities. Adult patients diagnosed with MM were subsequently selected from this cohort. Disabilities were categorized as physical, communication, intellectual or psychological, and affecting the major internal organs. RESULTS: The cohort included 4,090 patients with MM, with a significantly lower rate per 100,000 persons among people with disabilities than among people without disabilities (29.1 vs. 39.4, p < 0.001). People with disabilities were more likely to undergo dialysis treatment at the time of diagnosis (16.3% vs. 10.0%, p < 0.001), but were less likely to undergo autologous stem cell transplantation (37.5% vs. 43.7%, p=0.072). This trend was more evident among patients with intellectual or psychological disabilities. The median overall survival among patients with disabilities was significantly shorter than that among patients without disabilities (36.8 months vs. 51.2 months, p < 0.001). CONCLUSION: In Korea, people with disabilities generally have a lower rate of MM diagnosis, receive less intensive treatment, and have a lower survival rate than people without disabilities.

PURPOSE: With the aging population, our current understanding of patients with cancer and their family caregivers needs to be expanded to older patients with cancer and their caregivers. By differentiating spousal caregivers and non-spousal caregivers, we aimed to investigate the universalities and particularities of caregiving for older patients with cancer. METHODS: Through 11 cancer centers in South Korea, 358 patient-caregiver pairs were recruited in this cross-sectional study. Patients were of gastric, colorectal, or lung cancers, and caregivers were those who accompanied the patients to the clinic. Along with socio-demographic variables, medical records of the patients, and caregiving-related measurements, the caregiver's quality of life (AC-QOL) was rated both by patients and by caregivers. RESULTS: Statistically significant attributes of ACQOL included patient's age, caregiving duration, caregiver's concern about financial burden, caregiver's self-evaluation of their own physical health, and work conflicts due to caregiving for spousal caregivers (R2â¯=â¯0.687). For non-spousal caregivers, caregiving duration, caregiver's concern about financial burden, caregiver's self-evaluation of their own physical health, and family conflicts due to work were found significant (R2â¯=â¯0.272). Also patients rated ACQOL in higher accordance with their spousal caregivers than with non-spousal caregivers. CONCLUSION: The needs of spousal caregivers and non-spousal caregivers might vary, which should inform the effective and efficient channeling of support for family caregivers. Future research suggestions, along with the study limitations, are discussed.

PURPOSE: Implementation of screening program may lead to increased health disparity within the population if participation differs by socioeconomic status. In Korea, colorectal cancer screening is provided at no or minimal cost to all people over 50 by National Cancer Screening Program. We investigated colorectal cancer screening participation rate and its trend over the last 10 years in relation to disabilities. MATERIALS AND METHODS: We linked national disability registration data with National Cancer Screening Program data. Age, sex-standardized participation rates were analyzed by type and severity of disability for each year, and factors associated with colorectal cancer screening participation were examined by multivariate logistic regression. RESULTS: Age, sex-standardized participation rate in people without disability increased from 16.2 to 33.9% (change, +17.7), but it increased from 12.7% to 27.2% (change, +14.5) among people with severe disability. People with severe disabilities showed a markedly lower colorectal cancer screening participation rate than people without disability (adjusted odds ratio [aOR], 0.714; 95% confidence interval, 0.713 to 0.720). People with autism (aOR, 0.468), renal failure (aOR, 0.498), brain injury (aOR, 0.581), ostomy (aOR, 0.602), and intellectual disability (aOR, 0.610) showed the lowest participation rates. CONCLUSION: Despite the availability of a National Cancer Screening Program and overall increase of its usage in the Korean population, a significant disparity was found in colorectal cancer screening participation, especially in people with severe disabilities and or several specific types of disabilities. Greater effort is needed to identify the barriers faced by these particularly vulnerable groups and develop targeted interventions to reduce inequality.

BACKGROUND AND AIM: Using the national disability registration linked to the cancer screening database in Korea, we examined (1) trends in the gastric cancer screening rate among people with disabilities over time, and (2) whether gastric cancer screening participation and modalities differed according to presence, severity, and type of disability. METHODS: We examined gastric cancer screening participation rates among individuals with registered disability, from 2006 to 2015. RESULTS: The age- and sex-adjusted rate for gastric cancer screening in people with disabilities increased from 25.9% in 2006 to 51.9% in 2015 (change: + 26.0%). During the same period, screening rates among people without disability improved from 24.7 to 56.5% (change: + 31.8%). Disability was associated with a screening rate [adjusted odds ratio (aOR) 0.89, 95% confidence interval (CI), 0.88-0.89]. Screening rates were markedly lower among people with severe disabilities (aOR 0.58, 95% CI 0.57-0.58) and people with autism (aOR 0.36, 95% CI 0.25-0.52), renal failure (aOR 0.39, 95% CI 0.38-0.39), brain injury (aOR 0.41, 95% CI 0.40-0.41), ostomy problems (aOR 0.53, 95% CI 0.51-0.55), intellectual disabilities (aOR 0.54, 95% CI 0.53-0.54), or mental disorders (aOR 0.55, 95% CI 0.54-0.56). The use of gastroscopy as the initial screening modality in people with disabilities was lower than in people without a disability. CONCLUSIONS: In spite of the availability of national gastric cancer screening program, we found significant disparities in gastric cancer screening participation, especially among people with severe disabilities and those with renal failure or brain-related/mental disabilities.
