Abstract: Objective This study aimed to systematically evaluate and mitigate risks associated with infectious disease prevention and control in general hospitals, with the ultimate goal of strengthening institutional capacity for infection management. Methods A hybrid risk analysis approach combining the Delphi technique and Failure Mode and Effects Analysis (FMEA) was employed to identify, assess, and prioritize key vulnerabilities in hospital-based infectious disease control processes. Following risk prioritization, evidence-informed interventions were designed and implemented for the highest-ranking issues, and their impact was rigorously measured through pre- and post-intervention comparisons. Results Twenty-two distinct risk elements influencing infectious disease management efficacy were identified and stratified by severity and likelihood using FMEA scoring. The five most critical areas demanding urgent action were: (1) fragmented or under-resourced internal structures dedicated to infection control; (2) outdated or non-integrated health information systems lacking real-time surveillance capabilities; (3) inconsistent application of triage and initial screening protocols; (4) variable adherence to standard infection prevention practices across clinical units; and (5) inefficient interdepartmental coordination during the transfer of suspected or confirmed infectious cases. Post-intervention outcomes demonstrated marked improvements: the timeliness of mandatory infectious disease reporting rose from 84.66% to full compliance (100%); case report completeness reached 100%, up from 97.89%; and the median reporting time per case was halved—from 10 minutes to 5 minutes. Statistically significant enhancements were observed across all evaluated compliance indicators (p < 0.001). Conclusion The synergistic application of the Delphi method and FMEA facilitates proactive risk detection, dynamic monitoring, and responsive mitigation—transforming reactive practices into a robust, iterative, closed-loop governance framework that substantially elevates the quality and reliability of infectious disease prevention and control in general hospitals.

Abstract: To address the technical challenge associated with the inability to utilize dredged sediments from existing rivers and lakes, this study focused on dredged ultra-soft soil from coastal areas. Taking into account various factors such as soil moisture content, dosage of curing agent and foaming agents, as well as fiber type, dosage, and size, research was conducted on lightweight solidification technologies suitable for fiber-reinforced high water content ultra-soft soil. The test results indicate: 1) The fiber reinforcement effect significantly improved the brittle failure mode of the solidified lightweight soil, substantially enhancing the structural stability and ductility, with basalt fiber providing the best reinforcement effect. 2) The increase in unconfined compressive strength of solidified lightweight soil ranged from 10.2% to 23.4% under different fiber dosages and lengths. When the fiber length exceeded 20 mm, the increase in strength gradually stabilized. With the increase of fiber dosage, the strength showed a trend of increasing first and then decreasing. 3) The 7d density-strength ratio of fiber-reinforced dredged solidified lightweight soil reached 100.49 kPa/(g·cm-3), representing increases of approximately 56.1%, 33.6%, 38.5%, and 28.0% compared to ordinary subgrade soil, conventional solidified soil, fiber-modified cement soil, and EPS-particle lightweight soil, respectively. The research findings can provide theoretical foundation for ultra-soft soil treatment in activities such as coastal tidal flat development, river dredging, and road subgrade renovation and expansion.
