PocketOSler may be the first handheld patient-tracking application that is truly faster than pen and paper. It is a patient tracking applet specifically designed to take full advantage of HanDBase 3.0's capabilities, including on-screen keypads, pop-ups to enable easy and rapid data entry, color-coded forms, alarms, and infrared synchronization and printing. Forms have been designed and tested so that all patient information is reachable within a few clicks. Fields include medications, allergies, events, H&P's, and procedures. PocketOSler also has a built-in age calculator to determine "day of life", as well as an I's and O's calculator to deal with those bedside charts which haven't been totaled up before morning rounds. Companion applets include PocketOSler Labs, which features familiar "stick figure" lab formats, and PocketOSler Devices, which has extensive fields to track how long patients have had virtually every indwelling device (Foley, intracranial bolts, etc.)
