The National Poison Data System (NPDS) is the data warehouse for the nation’s 55 poison centers. Each poison center submits de-identified case data to NPDS after providing necessary poison exposure management and information services to callers. This case information is uploaded to NPDS in near real time, making NPDS one of the few operational systems of its kind. Currently, the time to upload data for all poison centers is 4.87 minutes [4.38, 8.62] (median [25%, 75%]).
