Background:The objective of the study was to determine the impact of continuous care on health outcomes and cost of type 2 diabetes mellitus (T2DM) in Korea. Methods: A nationwide retrospective, observational case-control study was conducted. Continuity of treatment was measured using Continuity of Care (COC) score. Information of all patients newly diagnosed with T2DM in 2004 was retrieved from the National Health Insurance database for the period of 2002 to 2013. The study examined 2,373 patients after applying exclusion criteria, such as for patients who died from conditions not related to T2DM. Statistical analyses were performed using frequency distribution, simple analysis (t-test and chi-squared test), and multi-method analysis (simple linear regression, logistic regression, and survival analysis). Results: The overall COC score was 0.83±0.24. The average incidence of diabetic complications was 0.39 per patient with a higher COC score, whereas it was 0.49 per patient with a lower COC score. In both survival and logistic analyses, patients who had high COC score were significantly less likely to have diabetic complications (hazard ratio, 0.69; 95% confidence interval, 0.54 to 0.88). The average medical cost was approximately 3,496 United States dollar (USD) per patient for patients with a higher COC score, whereas it was 3,973 USD per patient for patients with a lower COC score during the 2006 to 2013 period, with a difference of around 477 USD, which is statistically significant after adjusting for other factors (β=-0.152). Conclusion: Continuity of care for diabetes significantly reduced health complications and medical costs from patients with T2DM.
The purpose of this study was to determine whether the introduction of diagnosis-related groups (DRGs) shifted the medical services from inpatient to outpatient settings. Using a difference-in-difference analysis, the changes in length of stay, outpatient visit days within 30 days before hospitalization, and outpatient visit days within 30 days after hospital discharge were evaluated. The length of stay was reduced after the DRG policy, consistent with previous studies. Outpatient visit days within 30 days before a hospital admission increased significantly after the policy change. In addition, outpatient visit days within 30 days after a hospital discharge increased in all the medical institutions excluding hospitals. The study findings are consistent with the expectation that providers respond to changes in the payment system to protect or enhance their economic interests. Health care providers in Korea responded to the DRG policy by reducing the intensity of inpatient treatment and transferring costs to outpatient settings.
This study estimates the financial burden of healthcare in Korea using the National Survey of Tax and Benefit panel data from 2009 to 2019. The sum of a household’s premium and out-of-pocket medical expenses defines the household financial burden of healthcare. We find that the household financial burden is regressive to income. We also find that the high burden household whose financial burden is over 10% of their household income accounts for about 30% of total household. This result suggests that equity in contribution to healthcare finance does not work well in Korea, which chose the universal health system that emphasizes the progressive contribution by income to medical finance.
BackgroundThis study examines whether bed days are alternative methods to medical care use for treating a particular illness. If bed days at home are considered as an alternative to medical treatment, then medical care use and bed days at home should be influenced by an individual’s health insurance status.MethodThis study uses data from the 2003 Medical Expenditure Panel Survey (MEPS) on medical care use and bed days at home for each contracted illness of non-working married women.ResultsThe results suggest that the health insurance status of non-working married women has considerable influence on their choice between medical care use and bed days at home. In addition, those with health insurance are more likely to use medical care and less likely to use bed days at home, but they tend to avoid the simultaneous use of medical care and bed days at home.ConclusionsIn contrast to previous studies’ findings indicating that absences from work and medical care use among working males may be complements, this study’s results for non-working married women without health insurance suggest that they use rest and medical treatment as substitutes, not complements.
