An Integrated FMEA-RCA Risk-Management Approach for Deep Vein Thrombosis Prevention in Patients Undergoing Total Knee Arthroplasty.

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: To explore the effectiveness of Failure Mode and Effects Analysis (FMEA) combined with Root Cause Analysis (RCA) in deep vein thrombosis (DVT) risk management for patients undergoing total knee arthroplasty (TKA). Methods: In this prospective, non-randomized, quasi-experimental before-after design study, consecutive patients undergoing primary unilateral TKA were allocated according to admission period to receive either routine DVT risk management or an integrated FMEA-RCA program. Sample size calculation indicated that at least 64 patients per group were required, and 68 were enrolled in each group. Outcomes included RPN values, DVT incidence, length of stay, and HSS knee scores assessed preoperatively and at 6 weeks postoperatively. Results: The RPN values for all eight high-risk failure modes in the DVT prevention process were lower in the intervention group than in the control group (all Bonferroni-adjusted P values < 0.00625). The incidence of DVT was significantly lower in the intervention group than in the control group (5.88% vs 23.53%; χ Conclusion: Combining FMEA with RCA could help identify key nursing control points in DVT prevention for patients undergoing TKA.
