ER visits of asthmatic patients and cost of therapy

 Write a literature review comparing the worldwide experience of ER visits of asthmatic patients with the experience of ER visits of asthmatic patients in Saudi Arabia and the cost of therapy. The literature review should utilize several sources in which you can draw arguments that express different opinions. Use academic language and cite the references used in the text with their page number (Smith, 2013, p. 3) even if it is not a direct quote as I would like to go back to the references mentioned. Avoid using direct quotes, instead paraphrase. You can use from the sources attached with the order and any external sources you find useful and interesting.
