OBJECTIVE: Continuation and maintenance ECT (c-/m-ECT) are effective in the prevention of relapse and recurrence of both affective and psychotic disorders. However, data are scarce concerning the trajectories of severe mental disorders after the end of c-/m-ECT. This prospective study investigates the clinical outcome of patients with versus without modifications of their c-/m-ECT schedules.

METHODS: In the context of the COVID-19 pandemic, ECT capacities were restricted at many clinics in early 2020. All patients receiving c-/m-ECT in March and April 2020 at our department (n = 53, unipolar depression, bipolar disorder, schizophrenia) were followed up for six months to investigate the impact of treatment modifications imposed by the pandemic. Based on individual decisions, c-/m-ECT was either (a) continued without modification, (b) continued with reduced frequency, or (c) discontinued.

RESULTS: Both reduced frequency and discontinuation of c-/m-ECT were associated with significant clinical deterioration as measured by CGI-I (Clinical Global Impression Scale - Global Improvement) during the six-month follow-up when compared to the subgroup of patients without any treatment modification (p = 0.005, p = 0.011). Furthermore, patients with discontinued or reduced c-/m-ECT showed significantly higher rates of rehospitalizations (p = 0.028) and new acute courses of ECT (p = 0.018).

CONCLUSION: Despite the limitations of a heterogeneous and relatively small sample, our study strongly corroborates the effectiveness of c-/m-ECT in a real-world population. Especially, patients with shorter time since index ECT seem to be at high risk for severe clinical deterioration in the case of treatment discontinuation or reduction.
