Future impacts of colectomy healthcare pathways on quality of care in bundled payment experiments, a national retrospective cohort in France.
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
objectivesTo perform an ex-ante evaluation of French bundled payment experiments to evaluate the potential effects on hospital readmission and length of stay (LOS), and whether it could be used as a lever for improving quality of care after initial stays for surgery.
designA retrospective cohort analysis was performed using data from the French National Health Data System (SNDS).
settingWe used hospital and ambulatory data for colectomy between 2014 and 2016 (exhaustive French national data). The national database included 42,603 cancer colectomy stays during the study period.
participantsThe inclusion criteria were stays coded in the database with a principal diagnosis of colon cancer and a colectomy procedure excluding total colectomy, identified from the diagnosis related group. All partial colectomies performed in France from the 1st January 2014 to the 30th June 2016 were included, except those that met exclusion criteria, which were: admission to emergency departments, having already undergone a total colectomy (no time limit), or having undergone a partial colectomy in the previous year. Patients who died during the bundled payment period (45 days before the index stay and up to 90 days after) were excluded from the analysis. These criteria were selected and validated by the stakeholders who developed the bundled payment specifications. PRIMARY AND SECONDARY OUTCOME MEASURES: The main outcome was the variation in readmissions as a function of the initial LOS using a segmented regression method, and controlling with variables used by the health authorities. We also produced models by sector (public/private) and practice (Enhanced Recovery After Surgery [ERAS] model or not).
resultsWe obtained a J-shaped curve including two distinct parts, with a breakpoint at five days for patients without major comorbidities. Before the breakpoint, increased LOS was associated with a lower probability of readmission (coefficient = -0.016, 95%CI [-0.011;-0.021], p < 0.01). After the breakpoint, there was a progressive increase in readmissions as LOS increased.
conclusionsOur work suggests that improving the care pathway could reduce readmissions. Hospitals should focus on getting closer to the breakpoint, and care pathway models that reduce LOS, such as ERAS, should be encouraged for colectomy stays.
