Is preoperative emergency department utilization associated with postoperative healthcare utilization after total joint arthroplasty? A social vulnerability index based analysis.
Article in PloS one, 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
backgroundAs the need for total joint replacement increases with an aging population, there is increased attention to perioperative healthcare utilization. Efforts to mitigate complexity which may lead to deviations from successful surgical outcomes are critical, now more than ever. Analysis of predictive variables associated with increased healthcare utilization postoperatively can aid the effort to decrease emergency department (ED) visits and overall burden to the healthcare system.
methodsA retrospective review was completed of all patients with total knee or total hip arthroplasty between 2017 and 2020 at a single institution. Inclusion criteria were patients who underwent primary, elective total knee or hip arthroplasty and received a minimum of one year follow up. Zip code was used to determine the social vulnerability index (SVI) for each patient. Preoperative ED visits were collected for 90 days and 12 months prior to surgery.
resultsThere were 1,059 patients included, 193 with an ED visit 12 months prior to surgery and 45 with an ED visit 90 days prior to surgery with an average SVI of 0.50. Analysis of the postoperative outcomes demonstrated 104 patients with ED visits within 90 days following the procedure. Comparisons between SVI and all preoperative and postoperative variables demonstrated no statistical significance. Preoperative ED visit within 90 days or 12 months of surgery was associated with increased likelihood of postoperative ED visit within 90 days (p < 0.001, OR 4.64; p < 0.001, OR 3.78). Preoperative ED visit within 90 days or 12 months was also associated with increased risk of readmission (p = 0.008, OR 6.09; p = 0.005, OR 3.80) and revision surgery or reoperation (p = 0.039, OR 3.57; p = 0.041, OR 2.20).
conclusionPreoperative ED visit within 90 days or 12 months prior to surgery is a strong predictor of postoperative ED visit, readmission, and overall perioperative healthcare utilization regardless of socioeconomic factors.
