RESUMO
OBJECTIVES: Mild cognitive impairment, a pressing concern in the face of a rapidly growing global older adult population, necessitates effective management strategies focused on sustained symptom relief and preventing deterioration. Community Dementia Care Centers, in partnership with in-network hospitals, aim to provide support for preventing mild cognitive impairment and dementia. Medical counseling, influenced by in-network hospitals, is crucial for tailoring interventions to the cognitive abilities and specific needs of each older adult, protecting against dementia. Disparities in the number of in-network hospitals and healthcare infrastructure can contribute to uneven access to dementia care, thereby creating health inequities. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Using data from the Korea Community Health Survey (2018-2019), this study focused on South Korean individuals aged 60 and older in 17 metropolitan areas and provinces. METHODS: A multiple regression analysis was used to examine the relationship between the average number of in-network hospitals and medical counseling experience, considering sociodemographic factors and related variables. RESULTS: Areas with a higher average number of in-network hospitals exhibited increased medical counseling experiences. Significantly higher odds for medical counseling experience were observed in regions with "more than 5 hospitals" (1.36; 95% CI, 1.20-1.54; P = .000) than those with "3 or fewer hospitals." CONCLUSIONS AND IMPLICATIONS: This study underscores the importance of infrastructure, particularly collaborative hospitals that support Community Dementia Care Centers, in influencing individual dementia management and prevention. These findings highlight the significance of dementia prevention and management infrastructures, emphasizing the need for practical assistance, particularly in regions crucial for achieving health equity.
RESUMO
BACKGROUND: In aging populations, more elderly patients are going to the intensive care unit (ICU) and surviving. However, the specific factors influencing the occurrence of post-intensive care syndrome in the elderly remain uncertain. OBJECTIVE: To investigate the association between socioeconomic status (SES) and risk of developing dementia within two years following critical care. METHODS: This study included participants from the Korean National Health Insurance Service Cohort Database who had not been diagnosed with dementia and had been hospitalized in the ICU from 2003 to 2019. Dementia was determined using specific diagnostic codes (G30, G31) and prescription of certain medications (rivastigmine, galantamine, memantine, or donepezil). SES was categorized into low (medical aid beneficiaries) and non-low (National Health Insurance) groups. Through a 1:3 propensity score matching based on sex, age, Charlson comorbidity index, and primary diagnosis, the study included 16,780 patients. We used Cox proportional hazard models to estimate adjusted hazard ratios (HR) of dementia. RESULTS: Patients with low SES were higher risk of developing dementia within 2 years after receiving critical care than those who were in non-low SES (HR: 1.23, 95% CI: 1.04-1.46). Specifically, patients with low SES and those in the high-income group exhibited the highest incidence rates of developing dementia within two years after receiving critical care, with rates of 3.61 (95% CI: 3.13-4.17) for low SES and 2.58 (95% CI: 2.20-3.03) for high income, respectively. CONCLUSIONS: After discharge from critical care, compared to the non-low SES group, the low SES group was associated with an increased risk of developing dementia.
