Abstract
Background COVID-19 has spread rapidly around the world. The Austrian government implemented
a lockdown on 16 March to contain further spread of the disease. We investigated the
effects of lockdown on acute upper gastrointestinal (GI) bleeding in Austria.
Methods We contacted 98 Austrian hospitals performing emergency endoscopies. The hospitals
were asked to report upper GI endoscopies performed for recent hematemesis, melena,
or both, and exhibiting endoscopically visible signs of bleeding. The study period
was from 3 weeks before (calendar Week 9) to 3 weeks after (Week 14) initiation of
the lockdown.
Results 61 % of Austrian hospitals, and importantly all major state hospitals, responded.
A total of 575 upper GI bleedings occurred during the 3 weeks before and 341 during
the 3 weeks after initiation of lockdown (40.7 % reduction). There was a 54.6 % decline
in nonvariceal bleeding events at Week 14 compared with Week 9 (89 vs. 196), whereas
rates of variceal hemorrhage did not change (15 vs. 17).
Conclusions National lockdown resulted in a dramatic decrease in upper GI bleeding events in
Austrian hospitals.
