    ObjectiveInadequate stocking of essential antidotes in hospitals is an internationally documented problem. A concrete and sustainable system-wide solution for easy access to antidotes in emergency departments (EDs) was developed and implemented in Nova Scotia, Canada.MethodsAntidote stocking guidelines and a systemwide antidote management strategy were established. A standardized collection of antidotes housed in highly visible containers in provincial EDs was implemented for timely access. Antidote-specific online administration guidelines were developed. Using the poison centre for surveillance, the antidote program maintained a database of antidote utilization patterns; 11 years of data were available for analysis.Results2/2 (100%) tertiary care, 9/9 (100%) regional EDs, and 21/25 (84%) community EDs in Nova Scotia stock antidote kits, for an overall compliance rate of 32/36 (89%). A total of 678 antidotes (excluding N-acetylcysteine) were used for 520 patients. The distribution of antidote use by hospital type was 99/678 (14.6%) at community hospitals, 379/678 (55.9%) at regional hospitals, and 200/678 (29.5%) at tertiary care hospitals. The five most commonly used antidotes were: naloxone 143/678 (21.1%), fomepizole 111/678 (16.4%), glucagon 94/678 (13.9%), calcium 70/678 (10.3%), and sodium bicarbonate 67/678 (9.9%). Of the 520 patients in whom antidotes were used, death occurred in 3% (15/520), major outcomes in 35% (183/520), and moderate outcomes in 39% (205/520).ConclusionThe Nova Scotia Antidote Program demonstrates that a solution to inadequate antidote stocking is achievable and requires a system-wide approach with ongoing maintenance and surveillance. The frequency and distribution of antidote usage documented in this program supports the need for enhancement of emergency preparedness. The poison centre and hospital pharmacies are crucial to surveillance and maintenance of this program.
