General Software Description

Your pharmacovigilance database contains a wealth of important information about your products. The extensive mining and reporting capability of PV-Analyzer brings this knowledge to your fingertips allowing you to prepare detailed analyses and graphical outputs for both internal and external use.

With PV-Analyzer you can rapidly calculate key statistical measures that are widely used by regulatory authorities such as PRR, ROR, and MGPS and apply smart stratification to examine the database and detect where customizable thresholds have been exceeded.

The application integrates easily with PV-Works, other PV solutions, and various external data sources to increase flexibility in preparing such important metrics.

Benefits of PV-Analyzer solution

  • Industry standard – proven software used by key regulatory authorities to perform signal detection
  • Validated solution – fulfill requirements of internal and external regulatory audit
  • Ensure compliance – implement a structured signal detection procedure and track review of analysis
  • Integrated solution – capable of drug safety, product defect and even technical enquiry data
  • Optimized for business user – empower your product experts to perform signal detection without persistent input from IT

Data Mining

  • Run flexible queries to return results in a grid that can be sorted, filtered, grouped, printed, and exported
  • A three dimensional cube / pivot table which allows users to “slice and dice” data “on the fly”, comparing and sub-setting data at will
  • Examine case data from the perspective of product – sign pairs
  • Apply multiple mathematical functions such as count, sum, average, max / min, standard deviation etc.
  • Built-in “top-n” results function

Statistical Calculation

  • Create frequentist statistics such as PRR, ROR, OE, Chi-Square
  • Create Bayesian statistics such as EBGM, MGPS, IC and confidence intervals
  • Define both nominator and denominator source data sets
  • Aggregate clinical signs into different MedDRA / VeDDRA levels e.g. SOC, PT
  • Group target products into logical subsets e.g. by generic nameor product family
  • Analyze the effects of interacting products
  • Analyze by batch number
  • Stratify case data by any number of factors such as country, date, gender, dosage form as well as user-defined groups e.g. age / weight ranges (or species / breed for veterinary data)
  • Identify potential signals against customisable thresholds
  • Compare results against previous calculations and see visual indication of changing trends
  • Drill down from a statistical result back to PV-Works in order to view the contributing cases
  • Statistical results are stored in the PV-Analyzer database for tracking review comments

Graphical Reporting & Export

  • Graphical presentation of all base data and derived results
  • All grid and cube results can be printed or exported to Excel
  • Export potential signals for workflow managed review and processing
  • Watch-list function to monitor and alert users of specific data situations
  • Advanced report writing tool to support the ad-hoc development of other required outputs


PV-Analyzer includes a wide range of configurable options to give the business users power to explore the safety data without any support from their IT colleagues, e.g.:

  • Define configuration groups using almost any parameter e.g. regions, age groups, breed groups (for veterinary data) and use these either on the cube or in statistical analysis
  • Standardize the names of concomitant medications to overcome spelling variations in the case data
  • Define expected clinical signs per product and sub-set statistical results into labelled / unlabelled groups
  • Define alert thresholds for each product and apply these to statistical results to identify more likely signals


  • Available as cloud based solution
  • On-site deployment scalable from single PC to corporate solution
  • Oracle database on Windows / UNIX / Linux servers
  • Separate database to PV solution to optimize performance
  • Compatible with Citrix, 2X, Windows RDP and other thin client middleware
  • Agile development methodology
