"Long lie trauma" patients: retrospective analysis of a patient cohort presenting to a university hospital emergency department

Background Patients discovered recumbent, helpless and incapacitated, awake or unresponsive are referred to as "long lie trauma" (LLT) in the German medical jargon. Yet, a characterization of this cohort is missing. Methods We retrospectively analyzed all LLT patients admitted to the emergency department of the University Hospital Cologne from July 2018 to December 2020. Results A total of 50 LLT patients (median age 76 years, median time on the ground 13.5 h) were identified. The FD was most often attributed to primary cerebral causes in 40% of the cases (20% ischemic stroke, 16% intracranial hemorrhage, 4% epilepsy), intoxication/overdose (12%), and trauma (10%). It was often associated with infection (52%), injury (22%), hypovolemia (66%), acute kidney injury (20%), and severe rhabdomyolysis (creatine kinase >= 5000 U/l, 21%) as well as severe hypothermia < 32 degrees C (20%). Overall, 69% of the patients were admitted to an intensive care unit and in-hospital mortality was 50%. Conclusion The term "long lie trauma" describes a complex clinical situation, in which various conditions lead to an incapacitated state with acute onset, which then causes further adverse health effects. Trauma or tissue damage were no obligatory requirement in this syndrome. Considering the high morbidity and in-hospital mortality, patients should initially be treated in the emergency room by an interdisciplinary team.
