Did government subsidy program improve quality of care for children with complex chronic conditions in children's hospitals? A quasi-experimental study in South Korea.
Article in Clinical and experimental pediatrics, 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: Despite advances in medical technology, the number of children with complex chronic conditions (CCC) is increasing. Pediatric critical care involves high cost and low revenue. To address this issue, the Korean government designated and financially supported Specialized Public Medical Centers for Children (SPMCCs). However, rigorous evidence of their effectiveness remains limited. Purpose: We analyzed 30-day readmission rates to determine whether SPMCC designations contributed to improvements in pediatric critical quality of care and assess the presence of a measurable policy effect on readmission reduction. Methods: We included pediatric patients aged 0-18 years with a principal diagnosis of CCC and received care at SPMCCs between 2015 and 2021 using data from the customized National Health Insurance Service database. We applied an interrupted time series analysis with segmented regression to estimate the immediate level and postintervention slope changes in 30-day readmission rates following SPMCC designation. SPMCCs were classified into first and second designation groups based on the timing of their designation. Results: The 30-day readmission rates increased over time in the first and second designation groups. The first group showed a nonsignificant immediate level change at designation (-2.65 percentage points [pp]) but a significant decline in the postintervention slope of observed rates (-1.72 pp per quarter; P<0.001). Likewise, the adjusted 30-day readmission rates showed a nonsignificant level change (-0.75 pp; P=0.69) and a significant slope decline (-1.84 pp/quarter; P<0.001). The second group showed downward trends in 30-day readmission rates after designation in the observed and adjusted analyses; however, these trends were not statistically significant. Conclusion: The SPMCC designation was associated with a meaningful reduction in the trajectory of 30-day readmissions in the first group, providing evidence of a policy-induced reduction in readmissions. These findings highlight the importance of a sustained government investment in maintaining and expanding improvements and strengthening pediatric critical care services.
