Electroconvulsive therapy (ECT) and Psychiatric rehospitalization rates: a retrospective study.
Article in BMC psychiatry, 2024. 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
backgroundElectroconvulsive therapy (ECT) induces a generalized seizure under anesthesia with an electrical current for treatment-resistant patients and may be underutilized. To our knowledge, no large-scale, American, nationwide hospital system retrospective study has examined how ECT affects psychiatric rehospitalization chances.
methodsWe analyzed initial inpatient encounters for adults aged > 18 years at HCA Healthcare Behavioral Health Units from 2016 to 2021 with diagnoses of major depressive disorder with/without psychosis, bipolar disorder with/without psychosis, schizoaffective disorder, and schizophrenia. Excluding pregnancy and incarceration cases, we compared psychiatric rehospitalization rates within 365 days for patients receiving ECT versus those with the same diagnoses not receiving ECT. Subgroup analyses were conducted by diagnosis, length of stay, sex, and race. Detailed statistical analyses included bivariate analyses with Fisher's Exact Test and Wilcoxon Rank Sum Test.
resultsWe analyzed 38,109 distinct patients, 637 of which received ECT. The rehospitalization rate was 37.52% for ECT recipients versus 20.71% for non-ECT patients (p < 0.0001). ECT was associated with higher rehospitalization rates, particularly for severe diagnoses like psychosis (87.28%), schizoaffective disorder (3.77%), and schizophrenia (6.59%). ECT patients had significantly longer rehospitalization lengths of stay (mean 14.53 days vs. 6.54 days for non-ECT, p < 0.0001). White patients received ECT more frequently. Females received ECT more often, while males had higher rehospitalization rates.
conclusionsECT was associated with higher psychiatric rehospitalization rates and longer lengths of stay. This suggests ECT is more commonly used for complex, severe cases which may contribute to higher rehospitalization. Stronger social support and hospital and geographic ties among ECT patients may also play a role.
