Powerpath ® (validated database for CAP lab) ~ 15000 samples per year (~ 70,000 slides) Validated assays for > 30 analytes, FISH, CISH, mutation/copy number analyses = Millions of data points! In hundreds of Spreadsheets, emails, and other documents 3 | Oncology Translational Labs IMS| Raj Bandaru | 20101024 | Informatics | Business Use Only

  4. Life before the LIMSSpreadsheets, emails... Perl scripts • Samples and data recorded and tracked in Excel Spreadsheets. • Laboratory processes not tracked or in systems not accessible (Ventana system) • Pseudo audit trails (periodic time stamped back up of all data files using local scripts) • Multiple data entry, sample tracking sheets, Ventana staining systems, Aperio image database and Pathologist data entry. • Data transfer and sharing via emailing of spreadsheets • Data uploads to validated systems involved multiple independent and repeated cross checks using non validated scripts. 4 | Oncology Translational Labs IMS| Raj Bandaru | 20101024 | Informatics | Business Use Only

  5. Tough LifeErrors, duplication of effort, redundancy and confusion • Limited sharing/ security/audit trails/back up of the data • Structure of folder / files not defined by the process in the labs • Non transferable/ searchable data (color coding/ formatting of cells) • No controlled vocabulary/ validation of data entries. • Identified several errors and missing data (not entered or accidentally deleted) in 2 years of legacy data. (from spreadsheets prior to 2006). • Very difficult to implement automation, triggers, reminders. © Raj Bandaru 2010 “Black clouds over San Diego Bay” taken with DroidX, Oct. 23rd AM 5 | Oncology Translational Labs IMS| Raj Bandaru | 20101024 | Informatics | Business Use Only

  6. Off the shelf solutionsGaps Primary limitation of off the shelf systems was the need for extensive customization, expensive maintenance contracts/ consultation fees. ... And still require internal support teams. Watson LIMS IHC... FISH... Copy number... RNA profiling.. DNA sequencing...
