Mortalitet bland covid-19 antikoagulantia användare patienter och icke-antikoagulantia användare : en systematisk översikt

Sammanfattning: Background: Covid-19 is a serious infectious disease that was first discovered in China in 2019. The disease spread very quickly, infecting over 40 million globally and leading to more than a million deaths. The damage caused by the corona infection led to severe thromboembolic conditions that led to death. Therefore, anticoagulants were used in connection with corona to prevent the thromboembolic conditions. But has the use of anticoagulants in covid-19 patients really affected mortality?    Aim: To make a systematic review that explores whether anticoagulant use among COVID-19 patients affect mortality.    Methods: A systematic search was conducted September in 2022 of published studies on PubMed associated with mortality and use of anticoagulants in covid-19 patients. The articles reviewed were selected based on defined PICO and inclusion and exclusion criteria. Types of studies reviewed were cohort and case-control studies.    Results & conclusions:   A total of 20 different studies were studied and based on them it is concluded that anticoagulant treatment associated with lower mortality in severely ill covid-19 patients has been demonstrated. However, bleeding risk was observed in other covid-19 patients due to use of anticoagulants.
