Background: There are a few studies that evaluate preparedness and availability of antidotes in the emergency setting and none have been conducted in Qatar. Published studies show that timely availability of antidotes in the emergency department setting is a common issue. To address this, we conducted a study to evaluate antidote stocking and utilization in Qatar hospital pharmacies and emergency departments. Methods: In order to evaluate the appropriate use and timely administration of antidotes, research assistants prospectively collected data on ED patients. All ED patients who received any key antidote over the 6-month study period were identified through both ED and pharmacy records. In order to evaluate the stocking of the 31 most important antidotes in our main public hospitals, a survey assessing the stocking of these key antidotes was sent to the four general hospitals in Qatar, to determine their availability and whether they are stocked in the ED or only in the main pharmacy. Results: Poison exposure was evaluated in 471 cases. Antidotes were given within 30 minutes in 73% of cases, which included atropine, calcium, dextrose, flumazenil, naloxone, pralidoxime, sodium bicarbonate, thiamine, vitamin K and scorpion and snake antivenoms. Administration occurred later than 60 minutes in 2% of cases, exclusively with N-acetylcysteine and activated charcoal. Atropine, calcium, dextrose, naloxone, pralidoxime (2-PAM), sodium bicarbonate, and anti-venoms were clinically indicated 92% of the times they were ordered. N-acetylcysteine was indicated in only 51.5% of administrations. Significant variation in antidote stocking existed between hospitals, and there was no stocked hydroxocobalamin as antidotes for cyanide poisoning or fomepizole for toxic alcohol poisoning. Conclusion: Antidote stocking varied significantly between hospitals, and antidotes necessary for cyanide and toxic alcohol poisoning were deficient in all public hospitals. The implication of this research indicates the need for the development of national guidelines to standardize the stocking and administration protocols of the antidotes among the country’s public hospitals.
