Useful Resources for Medical Education and Clinical Development • Personal Information Manager (PIM) utilities • PDA-dedicated Web sites (e. g. , Hand. Held. Med) • Programming Environments (Code. Warrior, etc) and the Palm. OS Simulator (POSE) • Document Readers (Teal. Doc, Aportis. Doc, i. Silo, Mobi. Pocket, Hand. Held. Med Reader, Acrobat!) • Database managers (Jfile, Han. DBase) • Web (Clipping) browsers (e. g. Avant. Go) • Patient records (Patient. Tracker, Patient. Keeper, 5 Minute Clinical Consult) • Pharmacopeiae (e. Pocrates q. Rx, Tarrascon, PDR) • Decision Support (e. g. Med. Rules) • Reference Books (e. g. Harrison’s)

Useful Resourcesm for Medical Education Doc Readers Document Readers (use “DOC” PDB files) Teal. Doc, Aportis. Doc, i. Silo, Mobi. Pocket, Hand. Held. Med Reader Document can be prepared with standard programs (e. g. , Word) and converted to PDBs (e. g. , with a Word filter or Make. Doc. W. exe) DOCs can contain internal links and indexing Some DOC readers multifunction (e. g. , i. SILO handling HTML) DOC PDBs can be downloaded from Web sites for loading at synchronization

Useful Resources PDAs: Adobe Acrobat

Did We Have to Program PDA Applications from Scratch? • Processor code crafting (e. g. , C with Code. Warrior) takes plenty of time AND it would tend to be fairly platform specific • Code crafting also takes considerable lead time, SO • Wasn’t there any way to take advantage of existing Web development expertise AND repurpose existing Web content for more portable use on PDAs? • Could essentially the same content be used for different types of PDAs (e. g. , Palm OS and Pocket PC)?

Did We Have to Program PDA Applications from Scratch? NO! • Processor code crafting (e. g. , C with Code. Warrior) takes plenty of time AND it would tend to be fairly platform specific • Code crafting also takes considerable lead time, SO • Wasn’t there any way to take advantage of existing Web development expertise AND repurpose existing Web content for more portable use on PDAs? YES! • Could essentially the same content be used for different types of PDAs (e. g. , Palm OS and Pocket PC)? YES! • Avant. Go was an answer.

Useful Resources for Medical Education - Avant. Go What is it? Client- and server-side software for downloading and “clipping” content from Web servers AND interacting with online databases through Web Uis. Avant. Go can be used with Palm. OS, Pocket PCs, and RIM Blackberry 2 -way wireless email ‘pager’ devices What’s on the Client side? A streamlined, graphics-capable PDA Web browser (offline AND online) and workstation sync software (“Channels Manager”) that downloads Web pages filtered by the Avant. Go Server What’s on the Server side? A modified Apache Web server that maintains a database of userselected URLs and delivers this selected content to Clients at synchronization

Useful Resources for Medical Education - Avant. Go How do I get Avant. Go? The free (“public’) Client software is downloadable from www. avantgo. com. Some PDAs ship with it. Commercial (“Enterprise”) Server and Client software can be purchased from Avant. Go What’s kind of content can the public Avant. Go. Client deliver? Basic text and graphics Web pages, including tables and menus, but NO FRAMES; standard HTML, ASP, and Cold Fusion pages What else is included in the Enterprise Avant. Go client? ECMA 2 compatible Javascript capability (ECMA 3 coming), registered SSL key, ability to deliver PDB and PRC files, XML compatibility in next release

Special HTML Coding for Avant. Go Pages (Not much!)
