Kim GH, Song JS, Nam JW, Lee WR, Yoo KB. Trajectory of medical expenditure and regional disparities in hypertensive patients in South Korea. Front Public Health 2024; 12:1294045. [PMID: 38975357 PMCID: PMC11225734 DOI: 10.3389/fpubh.2024.1294045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 06/03/2024] [Indexed: 07/09/2024] Open
Abstract
The aim of this study is to understand how different regions influence the management and financial burden of hypertension, and to identify regional disparities in hypertension management and medical expenditure. The study utilized data from the Korean Health Panel Survey conducted between 2014 and 2018, focusing on individuals with hypertension. Medical expenditures were classified into three trajectory groups: "Persistent Low," "Expenditure Increasing," and "Persistent High" over a five-year period using trajectory analysis. Inverse Probability Weighting (IPW) analysis was then employed to identify the association between regions and medical expenditure trajectories. The results indicate that individuals residing in metropolitan cities (Busan, Daegu, Incheon, Gwangju, Daejeon, and Ulsan) and rural areas were more likely to belong to the "Expenditure Increasing" group compared to the "Persistent Low Expenditure" group (OR = 1.07; 95% CI; p < 0.001), as opposed to those in the capital city (Seoul) (OR = 1.07; 95% CI; p < 0.001). Additionally, residents of rural areas were more likely to be in the "High Expenditure" group compared to the "Persistent Low Expenditure" group than those residing in the capital city (OR = 1.05; 95% CI; p = 0.001). These findings suggest that individuals in rural areas may be receiving relatively inadequate management for hypertension, leading to higher medical expenditures compared to those in the capital region. These disparities signify health inequality and highlight the need for policy efforts to address regional imbalances in social structures and healthcare resource distribution to ensure equitable chronic disease management across different regions.

Comparison of Health Care Utilization in Different Usual Sources of Care Among Older People With Cardiovascular Disease in China: Evidence From the Study on Global Ageing and Adult Health. Int J Public Health 2024; 68:1606103. [PMID: 38234446 PMCID: PMC10792126 DOI: 10.3389/ijph.2023.1606103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 12/14/2023] [Indexed: 01/19/2024] Open
Abstract
Objectives: To compare the health care utilization in different usual sources of care (USCs) among the elderly population with cardiovascular disease in China. Methods: Cross-sectional data for 3,340 participants aged ≥50 years with cardiovascular disease from Global AGEing and Adult Health (2010)-China were used. Using the inverse probability of treatment weighting on the propensity score with survey weighting, combined with negative binomial regression and logistic regression models, the correlation between USCs and health care utilization was assessed. Results: Patients using primary care facilities as their USC had fewer hospital admissions (IRR = 0.507, 95% CI = 0.413, 0.623) but more unmet health needs (OR = 1.657, 95% CI = 1.108, 2.478) than those using public hospitals. Patients using public clinics as their USC had higher outpatient visits (IRR = 2.188, 95% CI = 1.630, 2.939) than the private clinics' group. Conclusion: The difference in inpatient care utilization and unmet health care needs between public hospitals and primary care facilities, and the difference in outpatient care utilization between public and private clinics were significant. Using primary care facilities as USCs, particularly public ones, appeared to increase care accessibility, but it still should be strengthened to better address patients' health care needs.

Abstract
Objective The extent of regional variations in cardiovascular risk and associated risk factors in patients with gout in South Korea remains unclear. Therefore, we aimed to investigate the risk of major cardiovascular events in gout patients in different regions. Methods This was a nationwide cohort study based on the claims database of the Korean National Health Insurance and the National Health Screening Program. Patients aged 20 to 90 years newly diagnosed with gout after January 2012 were included. After cardiovascular risk profiles before gout diagnosis were adjusted, the relative risks of incident cardiovascular events (myocardial infarction, cerebral infarction, and cerebral hemorrhage) in gout patients in different regions were assessed. Results In total, 231,668 patients with gout were studied. Regional differences in cardiovascular risk profiles before the diagnosis were observed. Multivariable analysis showed that patients with gout in Jeolla/Gwangju had a significantly high risk of myocardial infarction (adjusted hazard ratio [aHR], 1.27; 95% confidence interval [CI], 1.02~1.56; p=0.03). In addition, patients with gout in Gangwon (aHR, 1.38; 95% CI, 1.09~1.74; p<0.01), Jeolla/Gwangju (aHR, 1.41; 95% CI, 1.19~1.67; p<0.01), and Gyeongsang/Busan/Daegu/Ulsan (aHR, 1.37; 95% CI, 1.19~1.59; p<0.01) had a significantly high risk of cerebral infarction. Conclusion We found there were regional differences in cardiovascular risk and associated risk factors in gout patients. Physicians should screen gout patients for cardiovascular risk profiles in order to facilitate prompt diagnosis and treatment.

HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:e5831-e5838. [PMID: 36073616 DOI: 10.1111/hsc.14014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 07/24/2022] [Accepted: 08/20/2022] [Indexed: 06/15/2023]
Abstract
Although continuous treatment leads to better patient outcomes, evidence regarding the effect of the continuity of care (COC) on preventable hospitalisation and medical expenses in Korea for patients with dyslipidaemia is insufficient. We evaluated the effect of COC on preventable hospitalisation and medical expenses for patients with dyslipidaemia. This study used National Health Insurance Sampling cohort data (2008-2015). We measured COC with the Bice-Boxerman index based on the outpatient visits of patients diagnosed with dyslipidaemia for the first time. Preventable hospitalisation included admission for cardiovascular disease (CVD) and all costs for outpatient visits. We evaluated the association of COC with preventable hospitalisation and medical expenses using a generalised estimating equation model. Patients (N = 53,372) with newly diagnosed dyslipidaemia participated. Compared to non-hospitalised patients, hospitalised patients had higher fragmentation scores for CVD, met more healthcare providers, had higher total outpatient visits and had a lower proportion of primary healthcare providers served. A higher fragmentation score was associated with an increased risk of hospitalisation (rate ratio [RR]: 1.873, 95% confidence interval [CI]: 1.520-2.309) and healthcare expenditure (RR: 1.381, 95% CI: 1.322-1.442). The magnitude of the effect of COC on hospitalisation differed according to patients' drug intake and residence location. Fragmentation of care was associated with preventable hospitalisation and increased healthcare costs, especially for patients taking medications/living in rural areas. It is necessary to promote a more effective COC.

BMC Public Health 2022; 22:1970.

Abstract
BACKGROUND Cardiovascular diseases (CVD) are emerging as the leading contributor to death globally. The usual source of care (USC) has been proven to generate significant benefits for the elderly with CVD. Understanding the choice of USC would generate important knowledge to guide the ongoing primary care-based integrated health system building in China. This study aimed to analyze the individual-level determinants of USC choices among the Chinese elderly with CVD and to generate two exemplary patient profiles: one who is most likely to choose a public hospital as the USC, the other one who is most likely to choose a public primary care facility as the USC. METHODS This study was a secondary analysis using data from the World Health Organization's Study on Global AGEing and Adult Health (SAGE) Wave 1 in China. 3,309 individuals aged 50 years old and over living with CVD were included in our final analysis. Multivariable logistic regression was built to analyze the determinants of USC choice. Nomogram was used to predict the probability of patients' choice of USC. RESULTS Most of the elderly suffering from CVD had a preference for public hospitals as their USC compared with primary care facilities. The elderly with CVD aged 50 years old, being illiterate, residing in rural areas, within the poorest income quintile, having functional deficiencies in instrumental activities of daily living and suffering one chronic condition were found to be more likely to choose primary care facilities as their USC with the probability of 0.85. Among those choosing primary care facilities as their USC, older CVD patients with the following characteristics had the highest probability of choosing public primary care facilities as their USC, with the probability of 0.77: aged 95 years old, being married, residing in urban areas, being in the richest income quintile, being insured, having a high school or above level of education, and being able to manage activities living. CONCLUSIONS Whilst public primary care facilities are the optimal USC for the elderly with CVD in China, most of them preferred to receive health care in public hospitals. This study suggests that the choice of USC for the elderly living with CVD was determined by different individual characteristics. It provides evidence regarding the choice of USC among older Chinese patients living with CVD.

Disparities in cardiovascular disease prevalence among middle-aged and older adults: Roles of socioeconomic position, social connection, and behavioral and physiological risk factors. Front Cardiovasc Med 2022; 9:972683.

Abstract
Introduction Cardiovascular disease (CVD) remains the leading cause of premature death globally and a major contributor to decreasing quality of life. In the present study, we investigated the contribution of social, behavioral, and physiological determinants of CVD and their different patterns among middle-aged and older adults. Methods We used harmonized data from 6 nationally representative individual-level longitudinal studies across 25 countries. We restricted the age to ≥50 years and defined cases as a self-reported history of CVD. The exposure variables were the demographic status (age and sex), socioeconomic position (education level, employment, and household income level), social connections (marital status and family size), behavioral factors (smoking, alcohol drinking, and frequency of moderate to vigorous physical activity), and physiological risk factors (obesity, presence of hypertension, and presence of diabetes). Mixed logistic regression models were fitted to investigate the associations, and dominance analysis was conducted to examine the relative contributions. Results In total, 413,203 observations were included in the final analysis, with the CVD prevalence ranging from 10.4% in Mexico to 28.8% in the United States. Physiological risk factors were the main driver of CVD prevalence with the highest dominance proportion, which was higher in developing countries (China, 57.5%; Mexico, 72.8%) than in developed regions (United States, England, 10 European countries, and South Korea). Socioeconomic position and behavioral factors also highly contributed but were less significant in developing countries than in developed regions. The relative contribution of socioeconomic position ranged from 9.4% in Mexico to 23.4% in the United States, and that of behavioral factors ranged from 5.7% in Mexico to 26.1% in England. Conclusion The present study demonstrated the different patterns of determinant contributions to CVD prevalence across developing and developed countries. With the challenges produced by different risk factors, the implementation of tailored prevention and control strategies will likely narrow disparities in the CVD prevalence by promoting health management and enhancing the capacity of health systems across different countries.

Abstract
Abstract
Objectives
The purpose of this study is to assess patients’ knowledge regarding statin–grapefruit interactions, to identify any pertinent demographic characteristics that may influence knowledge of this drug–food interaction, and to identify preferred patient sources of health information.
Methods
A cross-sectional study was conducted to collect data from statins users about the awareness regarding drug interaction with foods. Self-administered questionnaires have been distributed to collect data from statins users regardless of the type and the reason they administer these medications. Respondents were statins users visiting the King Fahd Hospital’s outpatient clinic (KFHU) and community pharmacies in the Eastern province of Saudi Arabia.
Key findings
Our study revealed that 62% of statin users never heard about the statin–grapefruit interaction. Only 11% have correctly recognized the interaction effect. Only 11, 21 and 6% of users have reported that they often/always received information on drug–food interaction from pharmacists, physicians and nurses, respectively. Users aged above 60 years had lower awareness than those aged <40 (6.0% vs. 14.1%). Similarly, the proportion was lower among users who had primary or lower educational attainment, unemployed or had income lower than 5000 SAR compared with that among the contrary groups. However, only income showed a statistically significant association (P = 0.007).
Conclusions
The majority of statin users have never heard about their interaction with food. Geriatrics, low-income and less educated patients had a lower level of awareness compared with their counterparts. Many patients may end up discontinuing their medications because of that interaction and the consequent side effects. Pharmacists are requested to play their expected role in providing adequate patient counselling to help improve patients’ awareness regarding safety concerns of statins medication.
