Reduction in hospitalizations and emergency psychiatric care due to social distancing measures during the COVID-19 pandemic

Objetivo: Assess the impact of the lockdown measures on hospitalizations and emergency psychiatric care in a capital of a Brazilian state. Methods: Psychiatric hospitalizations and emergency psychiatric attendances carried out between January 7th and May 28th, 2020, were evaluated, covering the periods before and after lockdown due to COVID-19 pandemic in the city of Fortaleza, capital of the state of Ceará, Brazil. The data in the two periods were described and presented in time series graphs. Attendances were also described according to the severity categories. Comparisons were performed using Mann-Whitney U test and test for proportions. Results: The daily average of hospitalizations and of attendances decreased in the evaluated periods from 16.0 to 10.8 (p < 0.001) and 67.9 to 35.0 (p < 0.001), respectively. This absolute reduction was observed in all categories of severity. No difference was observed in the proportion of severe attendances (2.3% vs. 2.8%; p = 0.207). The proportion of mild cases decreased from 18.6% to 10.7% (p < 0.001) and of intermediate severity cases increased from 79.1% to 86.5% (p < 0.001). Conclusion: The findings showed both a decrease in emergency psychiatric attendances and hospitalizations, which can lead to severe impacts in the absence of counterpart mitigation measures by the local mental health system.
