How DRG Payment Reform Shapes Inpatient Neurological Care in an Underdeveloped Region: Evidence from a Controlled Interrupted Time Series Study in Yunnan, China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: This study evaluates the impact of the DRG-based payment reform pilot, initiated in January 2023, in an underdeveloped city in Southwest China. The reform's implications are particularly relevant for resource-limited settings, where healthcare cost control and service efficiency are critical for improving patient care. Purpose: This study aims to evaluate the impact of this reform on the inpatient service capacity, cost, and efficiency of the Neurology Department in the leading hospital within a county-level medical community. Material and Methods: We conducted a controlled interrupted time series (ITS) analysis using monthly administrative data from January 2021 to June 2024, focusing on inpatients treated in the Neurology Department of M Hospital, A City, Yunnan Province. Eleven outcome indicators were assessed, including Total DRG Weight, Case Mix Index (CMI), Average Length of Stay (ALOS), and Average Inpatient Cost (measured in Renminbi, RMB). A comparable control group was used to strengthen causal inference. Results: Following the DRG reform, the Neurology Department experienced a 32.37% increase in Total DRG Weight, a 12.21% rise in CMI, and an 8.94% increase in the number of DRG groups, while ALOS decreased by 9.85%. The ITS model revealed a significant upward trend in Total DRG Weight (trend change = 2.16, Conclusion: The implementation of DRG-based payment reform in A City was associated with enhanced inpatient service efficiency in the Neurology Department, including improved case complexity management, shorter hospital stays, and reduced costs. However, medical equipment-related expenses remained unaffected, potentially due to increasing patient severity and ongoing technology investments. These findings offer valuable evidence for policymakers aiming to optimize hospital performance through payment system reform in resource-limited settings.
