Article Abstract

This study examines the inequality between people with and without disabilities regarding unmet healthcare needs and preventable hospitalization. We used the Korea Health Panel of 2016-2018; the final analytical observations were 43,512, including 6.95% of persons with disabilities. We examined the differences in contributors to the two dependent variables and decomposed the observed differences into explained and unexplained components using the Oaxaca-Blinder approach. Unmet healthcare needs and preventable hospitalizations were 5.6% p (15.36% vs. 9.76%) and 0.68% p (1.82% vs. 0.61%), respectively, higher in people with disabilities than in those without, of which 48% and 35% were due to characteristics that the individual variables cannot explain. Decomposition of the distributional effect showed that sex, age, and chronic disease significantly increased disparities for unmet healthcare needs and preventable hospitalization. Socioeconomic factors such as income level and Medical aid significantly increased the disabled-non-disabled disparities for unmet healthcare needs. Socioeconomic conditions increased the disparities, but around 35%-48% of the disparities in unmet healthcare needs and preventable hospitalization were due to unexplained factors, such as environmental barriers.

Background And Objectives: Over 12% of older Latinos in the United States have Alzheimer's disease and related dementias (ADRD), facing earlier onset of the disease and severe symptoms compared to non-Hispanic Whites. These disparities in ADRD among Latinos can lead to significant caregiver strain and burden in Latino ADRD caregivers. Notably, Latino ADRD caregivers have poor overall health outcomes and face systemic inequities including limited access to quality dementia care resources that impact their well-being significantly.

Introduction: There remains limited research exploring the experiences of informal carers from ethnically minoritised groups, particularly to illustrate perceptions of caring roles and challenges they may face to address unmet needs. While barriers such as language, cultural expectations and discrimination are acknowledged in wider literature, little is known about how these influence caregiving experiences or access to services in practice. This work seeks to better describe the barriers and facilitators impacting carers from ethnically minoritised groups, as well as illustrate possible influences of culture and carer identity affecting this under-researched population.

Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are common respiratory conditions that significantly impact patient health and contribute to substantial healthcare burdens. While conventional treatments offer symptom relief, many patients continue to experience persistent symptoms, side effects, or resistance to standard therapies. This highlights the growing need for novel, non-invasive, and sustainable therapeutic strategies to manage chronic airway inflammation.

Background: Women who use drugs (WWUD) experience increasingly worse outcomes from drug use as compared to men. Additionally, transactional sex, unstable housing, and unmet needs may further complicate their ability to get needed health care. To inform the design of gender-based, mobile health services, we sought perspectives on health care service delivery from WWUD and health care and harm reduction professionals (HHRPs) in Seattle, WA.
