Impact of Residents' Mass Resignation in Cardiovascular Surgery: A System Sustainability Perspective.
Article in Interdisciplinary cardiovascular and thoracic surgery, 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
objectivesIn February 2024, a nationwide resident resignation occurred in South Korea that persisted for more than one and a half years and caused unprecedented disruptions in teaching hospitals. This study evaluated the clinical and socioeconomic impact of resident absence on cardiovascular surgery at a tertiary teaching hospital.
methodsWe retrospectively reviewed 681 patients who underwent open-heart or aortic surgery between February 20 and November 30, 2023 (before resident absence) and in 2024 (resident absence). Each year was divided into 3 periods (Q1, Q2, and Q3) for temporal comparison. The primary outcomes were 30-day mortality, failure-to-rescue complications, and failure-to-rescue. Failure-to-rescue was defined as in-hospital mortality after one or more of the following failure-to-rescue complications: acute renal failure, respiratory complications (prolonged ventilation >24 h, pneumonia, or tracheostomy), stroke, reoperation, life-threatening arrhythmia, postoperative myocardial infarction, or culture-positive sepsis. Multivariable logistic regression was performed to identify independent risk factors.
resultsWhen comparing 2023 Q1 with 2024 Q1, surgical volume decreased from 154 to 65 cases (-58%) and did not return to 2023 Q1 baseline. Compared with the 2023 group, the median surgical waiting time of the 2024 group increased from 17 [IQR: 8-28] to 36 [IQR: 20-58] days (P < .001). Resident absence was not a risk factor for 30-day mortality but was an independent risk factor for both failure-to-rescue complications (OR 1.50, 95% CI 1.03-2.19, P = .035) and failure-to-rescue (OR 3.64, 95% CI 1.33-9.98, P = .012).
conclusionsThe nationwide resignation of residents revealed the structural vulnerability of South Korea's healthcare system, which relies heavily on residents' workforce. Surgical capacity decreased, waiting times increased, and rescue outcomes deteriorated. The resident-dependent healthcare system requires reform, with teaching hospitals treating residents primarily as trainees rather than as inexpensive labour.
