In a search to find effective treatments for COVID-19, chloroquine and hydroxychloroquine have gained attention. We aim to provide evidence to support clinical decision-making regarding medication for the treatment of COVID-19 by carrying out a systematic review of the literature. The electronic databases MEDLINE, EMBASE, Global Health, and HMIC were searched up to April 2020. Eligible study outcomes included: extubation or patient recovery. Relevant data were extracted and analysed by narrative synthesis. Our results included six studies in the review of which four studies were of good or fair quality. All eligible studies included were for coronavirus involving the use of either chloroquine or hydroxychloroquine to treat common symptoms such as fever, cough, shortness of breath and fatigue. Outcomes most commonly reported were improved lung function, viral clearance, and hospital discharge. Strong evidence to support the use of chloroquine and hydroxychloroquine in the treatment of COVID-19 is lacking. Fast track trials are riddled with bias and may not conform to rigorous guidelines which may lead to inadequate data being reported. The use of these drugs in combination with other medications may be useful but without knowing which groups they are suited for and when they may cause more harm than good. |
