The Impact of DRG Review Teams on Obstetric Disease Management and Cost Control: A Variance Analysis Approach.
Article in The journal of obstetrics and gynaecology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimThe global transition toward Diagnosis-Related Groups (DRG) payment systems has fundamentally reshaped hospital reimbursement landscapes, yet obstetric departments present distinctive implementation challenges owing to the dual-patient paradigm and inherent clinical heterogeneity of maternal-fetal medicine. This study investigates whether strategically constituted DRG review teams can optimize both cost containment and care quality in obstetric settings through variance analysis methodology.
methodsWe conducted a retrospective cohort analysis at Shenzhen Baoan Women's and Children's Hospital spanning June 2022 to June 2025, encompassing 120 obstetric cases stratified across major DRG categories. The analytical framework integrated Time Consumption Index (TCI), Cost Consumption Index (CCI), and Boston Matrix positioning analysis. Primary outcomes included cost variance patterns, length of stay trajectories, and composite quality indicators with statistical adjustment for patient complexity.
resultsMultidisciplinary DRG review team implementation yielded statistically significant improvements: TCI decreased from 1.15 ± 0.23 to 0.89 ± 0.18 (p < 0.001), representing 22.61% efficiency gains; CCI improved from 1.08 ± 0.21 to 0.91 ± 0.16 (p < 0.001), indicating 15.74% cost reduction. Average length of stay decreased from 6.21 ± 2.34 to 4.73 ± 1.87 days (p < 0.001), with mean cost savings of ¥1333.33 per case. Pharmaceutical expenses demonstrated the strongest correlation with total cost variance (ρ = 0.82, p < 0.001). Critically, quality indicators remained stable throughout implementation, with 30-day readmission rates maintained at 2.50% ± 1.20%.
conclusionsStructured multidisciplinary DRG review teams demonstrate substantial effectiveness in optimizing obstetric resource utilization while preserving care quality. Variance analysis provides a robust framework for identifying pharmaceutical cost management as the primary leverage point for system-wide optimization, informing targeted intervention strategies for DRG implementation within specialized obstetric contexts.
