👉 The laboratory in one of the clinics had serious staffing problems. Due to understaffing, doctors and laboratory technicians worked 12–14 hours a day without proper rest. This led to errors in calculating drug dosages – warfarin – based on laboratory data. One of the patients received a double dose of anticoagulants and was urgently hospitalized with severe bleeding.
