Measure your outcomes with pinpoint accuracy using Computer Adaptive Assessments

The AM-PAC™ on PAC-Metrix fully embraces Item Response Theory (IRT) using Computer Adaptive Testing (CAT) logic. This technology provides the most comprehensive assessment available.
  • Since all the questions in the item bank (269 of them) are scaled from most impaired to least impaired, the CAT uses the patient’s answers to move up or down the scale to find the best question to ask next.
  • Given the relative difficulty of performing a task in the item bank, the patient’s answer determines if a more difficult or less difficult question should be asked next. This dynamic selection of questions results in a dramatically reduced set of questions.

Assess based on fewer questions

In this example, the computer-adaptive assessment has scored the basic mobility domain. In only seven questions, a score of 60.54 with a standard error of 1.94 was generated. Using a paper-based short form (generic outpatient version) to score the same assessment would require 18 questions to come to a score of 60.94 with a standard error of 1.68. While the standard error is slightly better with the short form, it requires 11 more questions to achieve this outcome.


Complete assessments quickly!

The chart to the right illustrates the amount of time needed to complete the AM-PAC™ assessment across a sample of 826 patients.

  • Assessments with one domain averaged 2 minutes 15 seconds (7.4 questions)
  • Assessments with two domains averaged 4 minutes 13 seconds (15.7 questions)
  • Assessments with all three domains averaged 5 minutes 37 seconds (24.2 questions)

This patient sample illustrates the relative speed with which the assessments can be completed.

Offer your patients the convenience of home testing

The electronic AM-PAC™ automatically generates a secure patient internet link that allows patients to take the assessments anywhere, even at home. If you are tired of spending your 60 minutes of treatment taking assessments, you can shift this burden outside of treatment time, and let patients complete assessments from the comfort of their own homes.

Streamline documentation and physician reporting

The electronic AM-PAC™ automatically generates a patient assessment report at the end of every assessment. This report summarizes the critical data collected and provides it to you for inclusion in each patient’s medical record or into your electronic medical record. Additional reporting allows you, as therapist, to see how your patients are improving.

Customize the system to meet your unique workflow

PAC-Metrix offers a number of configurable options that allow you to adapt it to your workflow.  Since the AM-PAC™ requires patient participation, different organizations like to manage the patient’s flow through the appointment in different ways to maximize effectiveness.  This is especially important to make sure that the patient answers the questions effectively and questions get answered in a timely manner.

  • Therapists or therapy assistants with laptops can administer assessments with patients
  • Facilities with tablets (such as an iPad) can give patients the assessments during breaks in sessions
  • Some organizations use a computer or laptop in the gym area as a shared resource to administer assessments
  • A dedicated computer can be placed in the waiting area if it is large enough and patients can perform a simple identification process to take their assessments

PAC-Metrix also supports integration from external systems.  Using this integration, patients can be registered and accounts established automatically. Completion of the account creation process requires manual intervention, but with the automation option, this effort is significantly reduced.
