Inpatient burden of lung cancer and changes after a hospital performance reform: a real-world study.
Article in Frontiers in oncology, 2025. 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: Lung cancer places a substantial burden on hospital inpatient care, particularly in tertiary cancer centers. Evidence remains limited on how hospital performance-based management reforms are associated with inpatient efficiency and costs among patients with lung cancer. Methods: We conducted a retrospective, real-world study using inpatient administrative data from a tertiary cancer hospital in China between 2016 and 2020. Hospitalizations (admissions) of patients with lung cancer were identified, and patient records were linked to enable secondary patient-level analyses. Length of stay (LOS) and daily hospitalization costs were evaluated as complementary indicators of inpatient efficiency and resource utilization intensity. A hospital performance reform implemented in April 2018 was examined by comparing pre-reform (2016-2017) and post-reform (2019-2020) periods. An interrupted time series analysis (ITSA) was conducted using segmented regression on monthly geometric means of log-transformed outcomes at the hospitalization level. Multivariable patient-level regression analyses were conducted as secondary analyses. Results: A total of 25,331 patients hospitalized with lung cancer were included. After April 2018, LOS declined by approximately 1.6% per month (p < 0.001) relative to the pre-reform trend, while daily hospitalization costs increased by approximately 2.1% per month (p < 0.001) relative to the pre-reform trend. Patient-level analyses were directionally consistent, with the post-reform period associated with a 16.0% shorter LOS and a 31.9% higher daily cost. Sensitivity analyses excluding 2020 and restricting to index admissions yielded similar results. Conclusions: Among patients hospitalized with lung cancer, the hospital performance reform implemented in 2018 was associated with shorter hospitalization duration and higher daily costs. These findings suggest concurrent changes in inpatient efficiency and resource utilization intensity and highlight the importance of using complementary indicators when evaluating hospital management reforms in oncology care.
