The Impact of the COVID-19 Pandemic on Inpatient Admissions for Psychotic and Affective Disorders: The Experience of a Large Psychiatric Teaching Hospital in Romania.

The COVID-19 pandemic resulted in a global sanitary crisis and, in addition, elicited serious mental health consequences. The utilization of psychiatric hospital-based services acts as an indicator of public mental health. Therefore, this research sought to investigate differences in the numbers and characteristics of inpatient admissions for psychotic and affective disorders at the largest Romanian psychiatric hospital between the period of lockdown (16 March-15 May 2020) and another three corresponding periods: the same year in the pre-lockdown period (16 January-15 March 2020), the immediate post-lockdown period (16 May-15 July 2020), and two years later (16 March-15 May 2022). A retrospective analysis was performed. The study included a total of 6604 patients. Inpatient admissions decreased during lockdown in comparison with the pre-lockdown period and immediate post-lockdown period for psychotic disorders ( p < 0.001 and p < 0.001, respectively) and affective disorders ( p < 0.001 and p < 0.001, respectively). For both psychotic and affective disorders, a decrease in the age of the patients admitted during lockdown, as compared with the pre-lockdown period ( p < 0.05 and p < 0.001, respectively), was observed. The length of the hospital stay for affective disorders was higher immediately post-lockdown in comparison with the lockdown period ( p < 0.001). Collectively, the present findings provide a glimpse of the immediate and long-term consequences of the COVID-19 pandemic and lockdown measures on patients' access to mental healthcare in the form of hospitalization, and these findings could provide the basis for the development of a different approach to times of crisis.
