COVID-19 and Psychiatric Admissions: A Comparative Study of Pre-pandemic and Post-pandemic Psychosis Admissions in a South Florida Emergency Department

We noticed a subjective increase in psychosis admissions within our emergency department (ED) with the onset of the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to identify trends concerning admissions due to psychosis in the ED before and after the beginning of the COVID-19 pandemic. We analyzed 508 psychiatric admissions through the ED from October 2019 to October 2020, of which 367 cases of psychosis were identified. Statistical analysis was performed using T-tests and Pearson's correlation coefficient. T-testing showed mean psychosis admissions during the pandemic (March 2020 to July 2020) to be greater than admissions occurring during the pre-pandemic period (October 2019 to February 2020) (p = 0.04). Pearson's correlation coefficient identified the relationships between COVID-19 admissions and psychosis admissions during this time as positive (r = 0.5) but did not reach statistical significance (p = 0.06). Therefore, within our time frame, we did see a noted increase in psychosis by 22.9% during the pandemic compared to pre-pandemic times. Current research remains conflicted concerning psychiatric ED admissions during COVID-19, with some stating an increase and others finding a decrease. Our data showed a significant statistical increase in the mean number of psychosis cases when comparing pre-pandemic and pandemic admissions. These findings help add pertinent data to understand how psychosis admissions trended before and during the beginning of the COVID-19 pandemic, specifically in South Miami, Florida. It also provides a foundation for future studies by providing data points concerning mental illness within the vulnerable population of patients served in our community.
