With PDA access to updated clinical information, pharmacists can more easily incorporate evidence-based medicine into their patient-care services. Using PDAs, pharmacists can document patient encounters, consult clinical reference tools, conduct health assessments, provide patient education, track outcomes, and perform a growing number of other clinical tasks. Before purchasing PDA applications, pharmacists are advised to obtain a trial version of the software, ask colleagues for their opinions, and consult reliable reviews, if available.
