The impact of the COVID-19 pandemic on hospital admissions in a psychiatric ward in a general hospital in Greece.

The negative consequences of the COVID-19 pandemic and the subsequent restrictive measures on the mental health and well-being of the population and psychiatric patients have been widely recognized. Patients' treatment attendance and engagement with mental health services had been negatively affected by the pandemic, whereas patients were less likely to receive timely outpatient care. The pandemic also impacted the use of inpatient services. The aim of the present study was to explore the variability of attendance and admissions to a general hospital psychiatric ward over a 12-month interval after the onset of the pandemic (March 2020), compared to the respective 12-month pre-pandemic interval. A retrospective, observational pre/post study was performed, involving a general hospital psychiatric ward in Corfu, Northwest Greece, which serves an insular catchment area of approximately 100,000 inhabitants. For data analysis, c- and u-charts of statistical process control charts were employed, using monthly data (March 2019 to February 2021). Overall, a significant decline in attendance rates was observed, mostly accounted for by a 26.5% reduction in voluntary attendance rates (1516 patients prior vs. 1114 patients after the onset of the pandemic). The involuntary commitment of patients did not differ between the two periods (106 prior vs. 100 after the onset of the pandemic). Admission rates did not change significantly between the two periods. Diagnoses that exhibited significant variance in examinations between the two study periods were mood disorders and personality disorders, whereas there was no significant variation in the number of admissions across different diagnoses. Length of hospital stay increased significantly by 13.2% over the first year of the pandemic, from 25.57 days (Md= 13, IQR= 22) during the pre-COVID-19 period to 28.95 days (Md= 22, IQR= 28) during the COVID-19 period. Patients with schizophrenia and related disorders (Mean= 34.25 days, SD= 43.19) and mood disorders (Mean= 26.26, SD= 33.48) had prolonged hospital stays compared to other diagnoses. These findings highlight significant shifts in psychiatric care delivery during the pandemic and underscore the need for targeted interventions to address the evolving demands on mental health services during public health crises.
