Improved management of hospital-acquired infections with DRG-based payment system: an interrupted time‑series analysis.
Article in BMC health services research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundWhile diagnosis-related group (DRG) payment system has been shown to improve healthcare quality and reduce costs in high-income countries, its effectiveness in developing countries, particularly in terms of hospital-acquired infection (HAI) management, remains unclear.
methodsHAI surveillance data were collected from nine public hospitals in Zhejiang province, China, that implemented the DRG system in 2020. Changes in HAI incidence rates following DRG adoption were assessed using interrupted time-series analysis with a generalized additive model, covering the period from January 2016 to September 2023.
resultsThe HAI incidence rate demonstrated a general downward trend both before and after the DRG system's implementation. While no immediate change in the HAI rate was observed (-0.0124%; 95% CI: -0.1375%, 0.1127%) in the month immediately following DRG implementation (January 2020) when compared with December 2019, a significant monthly decline of 0.0072% (95% CI: -0.0124%, -0.0020%) was detected from January 2020 to September 2023, following the system's implementation. Additionally, a significant reduction in hospital stays prior to acquiring infection was noted post-implementation of the DRG system. The rising trend in the proportion of female patients, from 31.52% in 2016 to 40.00% in 2019, was eliminated after DRG adoption, with the proportion stabilizing thereafter. The age distribution, infection sites, and pathogen profiles remained largely stable throughout the study period.
conclusionsThese findings suggest that the implementation of the DRG system may contribute to improving HAI management, with notable reductions in the HAI incidence rate over time. Our study serves as a reference for other developing countries facing similar healthcare challenges, and provides valuable insights for improving healthcare quality and enhancing patient safety.
