Reducing Emergency Department (ED) Boarding Time Through Lean Redesign of the ED-to-Inpatient Admission Pathway: A Single-Center Quality-Improvement Study.
Article in Cureus, 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
Background Boarding inflates emergency-to-inpatient throughput time. We implemented a change package, pulling bed decisions upstream, disciplining handoffs, and removing a large diagnostic gate in a tertiary emergency department (ED), and evaluated its operational impact. Methodology We conducted a single-center, pre-post, quality-improvement study of adult ED admissions from January to August 2023. The baseline phase included admissions from January to March 2023, and the post-intervention phase included admissions from April to August 2023 after implementation of the Lean redesign on April 1, 2023. The primary endpoint was patient-level total admission cycle time, which was captured electronically from the electronic health record (EHR) and calculated as the number of minutes from admission order to inpatient bed arrival. Value stream mapping was utilized as a complementary process diagnostic tool to illustrate typical pathway lead times, categorize value-added and non-value-added activities, and determine process efficiencies. Map-based step medians were not considered to be directly interchangeable with aggregate patient-level cycle times, but rather as a diagnostic summary. Results Total admission cycle time as reported by EHRs (baseline, N = 217; post-intervention, N = 218) showed a reduction from 390 to 175 minutes (-215 minutes; 55% relative reduction). Non-value-added time fell from 290 to 90 minutes (-200 minutes; -69%) while value-added time saw a more modest change from 100 to 85 minutes (-15%). The process efficiency rose from 25.6% to 48.6% (+23.0 percentage points; ~+90% relative). Process-map results indicated that there was an improvement in the direction, and that three of the most significant sources of non-value-added time were diagnostic waiting, bed coordination, and transfer delays. Conclusions This single-center, pre-post, quality-improvement study found that a Lean redesign of the ED-to-inpatient admission pathway was linked to a clinically meaningful decrease in the admission cycle time and an increase in process efficiency. The results indicate that there may be value in pursuing earlier bed coordination, risk-based diagnostic gating, and standardizing handoffs as targets for future controlled or multisite evaluation, but not causal evidence.
