Hospital admissions (SHK) and bed capacity (SHK). Displays the psychiatric hospital admissions via the pED and bed capacity within the observed hospital in Berlin (SHK) during the Covid-19 period per month in comparison to the pre-Covid-19 period. Numbers in the pre-Covid-19 period (2019) were set to 100% for hospital admissions, i.e. for overall admissions, SUD admissions and SPD admissions (green line) . The bed capacity reached almost 100% in the pre-Covid-19 period (2019, grey line). The graph (blue line) shows that there were less overall admissions in the Covid-19 period, though the difference to the pre-Covid-19 period did not reach statistical significance. However, in the subgroup of SUD (dotted red line) and SPD (orange line) significant decreases in admissions via the pED were found. The yellow line shows a reduced bed capacity during the Covid-19 period
