Data-Driven Leadership in Internal Medicine Clinics: A DES-DOE Framework for Optimizing Patient Flow and Turnaround Time.
Article in Journal of healthcare leadership, 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
Purpose: Efficient leadership in healthcare requires actionable insights to improve both service quality and patient outcomes. This study aims to enhance outpatient service efficiency by applying a data-driven decision-support framework that integrates Discrete Event Simulation (DES) with Design of Experiments (DOE). The focus is on optimizing patient flow and reducing turnaround time in an internal medicine clinic of a Thai public hospital. Methods: A hybrid DES-DOE model was developed to replicate the clinic's real-world processes and assess the impact of key operational factors. The DES model, built in Arena, captured detailed workflows and resource constraints. A full factorial DOE design evaluated five critical variables: patient arrival patterns, physician availability, consultation start-time delays, pre-appointment blood testing, and proportions of patient categories (eg, cardiovascular, neurological, endocrine). A total of 32 scenarios were tested and analyzed using ANOVA. Results: All five factors significantly influenced turnaround time, with patient category proportions showing the strongest effect. The optimized scenario resulted in a 10.46% reduction in average turnaround time. These findings suggest that targeted, evidence-based adjustments can substantially improve patient throughput and clinic performance. Conclusion: This research provides healthcare leaders with a validated, replicable framework for improving operational efficiency through simulation-based experimentation. It demonstrates how integrating DES and DOE can support strategic planning, workforce management, and service design, ultimately contributing to better patient experiences and more resilient healthcare systems.
