Cancer care patterns in South Korea: Types of hospital where patients receive care and outcomes using national health insurance claims data.

ABSTRACT:

Background

Although strengthening coverage has improved cancer care, there are concerns related to medical distortion. Previous studies have only examined whether patients visit a specific hospital, and not the continuum of patients with cancer, resulting in a lack of evidence in South Korea. This study aimed to investigate the patterns in hospital type for cancer care and analyze their association with outcomes.

Methods

The data for this study were obtained from the National Health Insurance Services Sampled Cohort database. This study included patients with four types of cancer (top four cancer incidence in 2020): gastric (3353), colorectal (2915), lung (1351), and thyroid (5158) cancer. The latent class mixed model was used to investigate cancer care patterns, and multiple regression or survival analysis was performed to examine medical cost, length of stay (LOS), and mortality.

Results

The patterns in each cancer type were classified into two to four classes, namely, mainly visited clinics or hospitals, mainly visited general hospitals, mainly visited tertiary hospitals (MT), and tertiary to general hospitals through trajectory modeling based on the utilization of cancer care. Compared to the MT pattern, other patterns were generally associated with higher cost, LOS, and mortality.

Conclusion

The patterns found in this study may be a more realistic way of defining patients with cancer in South Korea compared to previous studies, and its association-related outcomes may be used as a basis to address problems in the healthcare system and prepare alternatives for patients with cancer. Future studies should review cancer care patterns related to other factors such as regional distribution.

Project description:BackgroundSince antimicrobial overuse and misuse can have substantial impacts on both public health and fetal well-being, it is essential to gain comprehensive insights into antimicrobial consumption patterns in pregnant women. This study aims to demonstrate antimicrobial utilization in pregnant women.MethodsWe conducted a population-based cohort study using National Health Insurance claims data from January 2009 to December 2020 in South Korea. The target population was pregnancies in women aged 15-45 years who gave birth between 2011 and 2019. The outcome measure was the percentage of antibiotic prescriptions by trimester, subgroup, diagnostic category, and therapeutic category. Antibiotics were defined as J01 in the WHO ATC/DDD classification. To analyze the factors that influenced antibiotic prescriptions, we conducted multivariate logistic regression analysis.ResultsAntibiotics were prescribed at least once in 1,808,588 (50%) of the 3,614,478 pregnancies. The proportion of deliveries with exposure to antibiotic therapy during pregnancy increased from 48% in 2011 to 54.8% in 2020. The prescription rate of antibiotics was highest in mothers younger than 25 years old, and it was lowest in participants aged 30-34 years. Also, antibiotic use was highest in the first trimester (30%) and lowest in the second trimester (18.2%). The most commonly used class was J01D (other beta-lactam antibacterials), which includes cephalosporins, and it accounted for 57% of the prescribed antibiotics. An increased probability of being prescribed antibiotics was associated with those younger than 25 years old, insurance (Medical Aid), hospitalization experience, an increase in physician visits, and comorbidities. For comorbidities, the OR was higher for respiratory tract infection (RTI), sexually transmitted infection, and urinary tract infection compared to those without disease, whereas it was decreased for diabetes and epilepsy.ConclusionThe prescribing rate of antibiotics to pregnant women in South Korea has remained stably high. Also, an increase in the use of broad-spectrum beta-lactam penicillin was noted. It is necessary to monitor antibiotics in pregnant women generally in accordance with recommendations.

Project description:BackgroundFluoroquinolones are one of the commonly used antibiotics for the initial empiric combination treatment. However, there is insufficient evidence to support the use of fluoroquinolones combination therapy for the treatment of hospital-acquired pneumonia (HAP). This study aimed to evaluate the effectiveness of fluoroquinolones as part of the empiric combination therapy for HAP using national health insurance claims data in Korea.MethodsWe compared the clinical outcomes of patients with HAP who received fluoroquinolones combination and those treated with cefepime or piperacillin/tazobactam monotherapy. The primary outcome was hospital mortality, and the secondary outcome was readmission caused by pneumonia as the primary cause of hospitalization within 7 days after discharge from index hospitalization. The association between the combination with fluoroquinolones and outcomes was evaluated with logistic regression analysis.ResultsAmong the 9,955 patients with HAP administered with cefepime or piperacillin/tazobactam, 4,918 (49%) received fluoroquinolones combination. During hospitalization, 1,059 (11%) patients with HAP died. Compared with the monotherapy group, the fluoroquinolones combination therapy group was associated with a higher mortality risk [adjusted odds ratio (OR), 1.30; 95% confidence interval (CI): 1.02-1.65]. After adjusting for potential confounding factors, the association remained significant in the non-high-risk HAP group (adjusted OR, 1.30; 95% CI: 1.02-1.66). Meanwhile, the mortality risk was similar between the fluoroquinolones combination therapy group and the monotherapy group of patients with high-risk HAP (adjusted OR, 0.99; 95% CI: 0.35-1.16). Among the patients alive and discharged (n=8,896), 152 (1.7%) were readmitted within 7 days after discharge. The fluoroquinolones combination therapy group was more likely to be readmitted because of pneumonia than the monotherapy group in patients with high-risk HAP (adjusted OR, 1.60; 95% CI: 1.04-2.47).ConclusionsFluoroquinolones combined with β-lactams was prescribed in nearly half of patients with low-risk HAP, and it was associated with a higher mortality risk in real-world practice. However, it was not associated with hospital mortality even in patients with high-risk HAP.
