Effects of implementing a clinical scoring system on the management of infants with RSV bronchiolitis.
Observational study in Wiener klinische Wochenschrift, 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
introductionRespiratory syncytial virus (RSV) is a common pathogen of lower respiratory tract infections in infants 1 month to 1 year of age. Infections with RSV are the most common cause for hospitalization for respiratory infections and present with a high rate of complications. Different scores for severity assessment currently exist but only few of them are well validated. The "Inpatient clinical pathway for evaluation/treatment of children with bronchiolitis" from the Children's Hospital of Philadelphia (CHOP) provides clear and concise guidance for severity grading and inpatient management.
aimIn 2019 we implemented a bronchiolitis scoring system and pathway in accordance with the CHOP pathway in our inpatient setting to assess and monitor children affected by bronchiolitis as well as to plan their discharge. This study investigated the length of stay before and after implementation of the score and the risk of readmission after regular discharge.
methodsData from all admitted infants 1 month to 1 year of age with a discharge diagnosis of acute bronchiolitis due to RSV (ICD 10-GM 2024 J21.0, n = 261) over a period of 9 years were evaluated, 5 winters (2014-2019, n = 140) before (group 1) and 4 winters (2020-2024, n = 121) after (group 2) implementation of the score.
resultsThe study population did not differ before and after implementation of the score with respect to age (group 1: mean age = 99.9 ± 87.3 days vs. group 2: 120.2 ± 85.6 days) and sex. The groups were equally sized with a mean of 28-30 patients per season. The average length of stay was 5.5 ± 3.4 SD days. Although the length of stay before and after implementation decreased on average by 0.4 days the result was not significant (5.6 ± 3.8 SD vs. 5.3 ± 2.8 SD days, p = 0.2). The readmission rate in total was very low (5/261, 1.7%) and only 1 patient had to be readmitted after implementation of the score (4/140, 2.8% vs. 1/121, 0.8%, p = 0.38).
conclusionThis structured clinical bronchiolitis pathway provides concise advice for outpatient as well as inpatient management. The length of stay did not differ before and after implementation. The score is a safe and useful tool for preventing readmission.
