Could seasonal patterns in ECT use impact service delivery? A nationwide study.
Article in International journal of mental health systems, 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
backgroundThe practice of electroconvulsive therapy (ECT) is constrained by limited resources. Anticipating recurrent peaks in demand is therefore essential for optimizing resource planning within public healthcare systems. This study examined seasonal patterns of ECT utilization in France over an extended period.
methodWe analyzed data from the French national administrative and medical database. Seasonal patterns in monthly ECT utilization time series from 2017 to 2023 were investigated using robust statistical methods.
resultsWe observed a clear seasonal pattern with a 12-month periodicity in monthly ECT utilization, accounting for 16% of the variance in use, with a major peak in December and a mean relative amplitude of 13.1%. Seasonal variation was observed across sex, age and diagnostic subgroups, although it was less pronounced among patients aged 24 years or younger and those with schizophrenia. Across all subgroups, ECT activity consistently peaked at the onset of winter, between November and December.
conclusionThese findings emphasize the need for ECT providers in France to anticipate recurrent winter peaks in activity. Proactive healthcare policies should ensure that medical staffing and equipements ressources are adjusted to accommodate predictable winter peaks in ECT demand.
