Systematic Review: Effectiveness of Corticosteroid Treatment in Anosmia Patients Post COVID-19

Abstract

This systematic review aims to determine the effectiveness of corticosteroids in treating anosmia in COVID 19 patients. This study used a systematic review approach in gathering data, from scouring through web-based journals into sifting through unrelated studies. The sifting process are levelled with varying degrees of specificity, from the PICO (Population, Intervention, Comparison, Outcome) which were Post COVID-19 patients with anosmia, corticosteroid therapy, placebo treatment, and an outcome in clinical recovery. The papers that fit the PICO criteria then were sifter through inclusion and exclusion criterias such as : it has to be a Randomised Clinical Trial (RCT), there are uses of corticosteroid, and the subjects were post covid patients. There were first searched with keywords of anosmia, COVID-19, corticosteroid through Pubmed (n=5) Google Scholar (n=200), SCOPUS (n=175), EBSCO (n=121), ScienceDirect (n=186). After gathering those papers, it was then judged based on their abstract for inclusion criterias and exclusion criterias. The final studies that were in this systematic review consists of three studies. The end results showed that there were no effectivity of corticosteroids in treating anosmia in post covid patients.
