The economic burden of rotavirus infection in South Korea from 2009 to 2012.

ABSTRACT: Rotavirus is a common cause of diarrhea worldwide, and vaccination prevents rotaviral gastroenteritis. Since the rotavirus vaccine was introduced in Korea in 2007, the prevalence of rotaviral gastroenteritis has decreased. However, little is known on the economic burden of rotavirus infection and its variations in Korea. Here, we estimated the economic costs of rotavirus infection from 2009 to 2012 using nationwide data from the National Health Insurance Service (NHIS) claims. Socioeconomic costs were subdivided into direct and indirect and measured with a prevalence-based approach. Costs were converted from Won to United States dollars (US$). The number of children <5 years old infected with rotavirus decreased from 21,437 to 10,295 during the study period, representing a decrease in prevalence from 947 to 443 per 100,000. The sum of direct and indirect costs also decreased, from $17.3 million to $9.6 million, and the days of admission decreased from 76,000 to 38,000. However, per capita expenditures slightly increased, from $809 to $934. Thus, the economic burden of rotavirus infection decreased after implementation of rotavirus vaccination. Including the vaccine as part of the national essential vaccination program could reduce the prevalence of and economic loss from rotavirus infection in Korea.

Project description:We evaluated the survival rates and medical expenditure in patients with lung cancer using a nationwide claims database in South Korea. A retrospective observational cohort study design was used, and 2,919 lung cancer patients and their matched controls were included. Medical expenditures were analyzed with the Kaplan-Meier sample average method, and patients were categorized into 4 groups by operation and primary treatment method (i.e. Patients with operation: OP = surgery, OP+CTx/RTx = surgery with anti-cancer drugs or radiotherapy; Patients without operation: CTx/RTx = anti-cancer drugs or radiotherapy, Supportive treatment). The 5-year medical expenditure per case was highest in the OP+CTx/RTx group ($36,013), followed by the CTx/RTx ($23,134), OP ($22,686), and supportive treatment group ($3,700). Lung cancer-related anti-cancer drug therapy was the major cost driver, with an average 53% share across all patients. Generalized linear regression revealed that monthly medical expenditure in lung cancer patients, after adjustment for follow-up month, was approximately 3.1-4.3 times higher than that in the control group (cost ratio for OP = 3.116, OP+CTx/RTx = 3.566, CTx/RTx = 4.340, supportive treatment = 4.157). The monthly medical expenditure at end of life was estimated at $2,139 for all decedents, and approximately a quarter of patients had received chemotherapy in the last 3 months. In conclusion, this study presented the quantified treatment costs of lung cancer on various aspects compared with matched controls according to the treatment of choice. In this study, patients with operation incurred lower lifetime treatment costs than patients with CTx/RTx or supportive treatment, indicating that the economic burden of lung cancer was affected by treatment method. Further studies including both cancer stage and treatment modality are needed to confirm these results and to provide more information on the economic burden according to disease severity.
