ABSTRACT
This study aimed to evaluate the cost-effectiveness of Chaiyin Granules compared with Oseltamivir Phosphate Capsules in the treatment of influenza(exogenous wind-heat syndrome). Based on a randomized, double-blind, positive drug parallel control clinical trial, this study evaluated the pharmacoeconomics of Chaiyin Granules with cost-effectiveness analysis method. A total of 116 patients with influenza from eight hospitals(grade â ¡ level A above) in 6 cities were selected in this study, including 78 cases in the experimental group with Chaiyin Granules and Oseltamivir Phosphate Capsules placebo, and 38 cases in the control group with Oseltamivir Phosphate Capsules and Chaiyin Granules placebo. The total cost of this study included direct medical cost, direct non-medical cost, and indirect cost. The remission time of clinical symptoms, cure time/cure rate, antipyretic onset time/complete antipyretic time, viral nucleic acid negative rate, and traditional Chinese medicine(TCM) syndrome curative effect were selected as the effect indicators for cost-effectiveness analysis. Four-quadrant diagram was used to estimate the incremental cost-effectiveness ratio. The results showed that Chaiyin Granules were not inferior to Oseltamivir Phosphate Capsules in the remission time of clinical symptoms of influenza(3.1 d vs 2.9 d, P=0.360, non-inferiority margin was 0.5 d). Compared with Oseltamivir Phosphate Capsules, Chaiyin Granules would delay the remission time of clinic symptoms of influenza for 1 d, but could save 213.9 yuan. 1 d delay in cure time could save 149.3 yuan; 1% reduction in the cure rate could save 8.2 yuan; 1 d delay in antipyretic onset time could save 295.4 yuan; 1 d delay in complete antipyretic time could save 114.3 yuan; 1% reduction in the 5-day cure rate of TCM syndrome could save 19.2 yuan. Different from other indicators, there was no statistically significant difference between two groups in the effect of negative conversion rate of viral nucleic acid, but the cost was lower and the effect was superior, and the pharmacoeconomics was not different from that of Oseltamivir Phosphate Capsules in the field of influenza treatment.

Since the initiation of the New Rural Cooperative Medical Scheme (NCMS) in 2003 in China, medical reimbursement plays an increasingly important role in reducing the familial burden of critical illness healthcare in rural China. However, the current medical reimbursement system is operated based on prefecture-level administrative boundaries, which may prevent some residents from accessing higher-quality medical resources. Using a reliable and high-accuracy geographic information system (GIS) dataset, this study investigates whether this reimbursement system restricts rural residents from freely seeking out medical services in the Hubei Province by employing a two-step floating catchment area (2SFCA). Results show that there are spatial differences between the catchment area of different graded medical centers and prefecture-level administrative boundaries. Spatial reimbursement boundaries should be readjusted so that most rural residents receive equitable coverage by the system and reimburse their medical expenses in a more convenient way. Therefore, we argue that the local government should delineate the spatial region of the medical reimbursement for rural residents according to an assessment of their spatial accessibility to different graded medical centers beyond prefecture-level boundaries. We also discuss potential methods for designing reimbursement boundaries and reimbursement management strategies that the Chinese central government could adopt.

OBJECTIVES: To evaluate the effects of the National Essential Medicine Policy (NEMP) on outpatient service utilization and expenditure in Tianjin, China. METHODS: All government-owned general primary health care centers (PHCs) within the Urban Employee Basic Medical Insurance in Tianjin were involved in the study. Of these, 49 PHCs implemented the NEMP in April 2009, and constituted the intervention group, and the remaining PHCs constituted the control group. Patients who had visited only one of the two groups at least once pre-NEMP (April 2008 to March 2009) and post-NEMP (April 2009 to March 2010) were included in the correspondent group. A difference-in-differences (DID) analysis was used to estimate the impacts adjusting for patients' sociodemographic characteristics and health status. Sensitivity was tested using the propensity score matching method. RESULTS: A total of 23,362 and 4,148 patients from the intervention and control groups were identified, respectively. The patients in the intervention group were older (63.7 years vs. 58.8 years; P < 0.001) and in worse health status, as indicated by the Quan-Charlson comorbidity index (1.0 vs. 0.7; P < 0.001), than their counterparts in the control group. The DID results controlling for other confounders indicated that the annual outpatient visits, total annual expenditure, drug expenditure, and out-of-pocket expenditure per capita for the intervention group were not significantly different from those of the control group. Propensity score matching-adjusted DID regression models demonstrated similar results. CONCLUSIONS: The China NEMP implementation did not affect the annual outpatient visits, total expenditure, drug expenditure, and out-of-pocket expenditure in the short term and the original policy goals were not met.
