Calculating PatientSecure Interactions

PatientSecure keeps track of every patient enrollment and every patient authentication scan as discrete events. While each individual scan is tracked and stored, the final outcome of the interaction with the patient is the key data point. There are common situations where multiple scans occur, but they represent only one interaction with PatientSecure.

The purpose of PatientSecure interactions is to determine the final outcome of the interaction with the patient and report on that as opposed to reporting on each individual scan. The reason for looking at the final outcome is so that when compared to a total registration count from the EMR, the utilization equation (below) accurately reflects whether or not PatientSecure was used for each registration. Counting each individual scan in this equation would incorrectly inflate the value.

Example

A registrar attempts to authenticate a patient in PatientSecure with a result of Biometric Didn't Match.

The registrar then enrolls the patient in PatientSecure.

In this situation, there were two scans (a Biometric Didn't Match scan and a Biometric Enrolled scan), but the final outcome of the interaction with the patient is a successful Enrollment.

Definitions

The following terms and definitions are used in this topic:

• Individual scans will be classified as Biometric Matched, Biometric Didn't Match or Biometric Enrolled.

• The final outcome of the interaction with the patient (PatientSecure Interactions) will be classified as Patient Not Found, Patient Found or Patient Enrolled.

• An authentication attempt is a single attempt to identify or verify a patient using a biometric.

  A single authentication attempt will result in either a Biometric Matched or a Biometric Didn't Match.

• Opt-outs are activities without a biometric. For more information on opt-outs, see Patient Opt-Out Tracking.

Scenarios and Results

Scenario	Results	Description
Zero to many Biometric Didn't Match scans followed by a Biometric Matched	Patient Found	Multiple authentication attempts with the same search criteria, are performed on the same machine by the same user, that result in zero to many No Match Found scans and end with a Biometric Matched scan. Each attempt must occur with 5 minutes of the prior authentication attempt in order to be grouped together. When viewing Interaction-based reporting, this is reflected as a single Patient Found. Child re-enrollments and LinkIDs count as authentications.
Zero to many Biometric Didn't Match scans followed by a Biometric Matched Scan	Patient Enrolled	Multiple failed authentications with the same search criteria, are performed on the same machine by the same user, followed by an enrollment with demographics that match the search criteria. The Biometric Enrolled scan must occur within 15 minutes of the last Biometric Didn't Match scan in order to be grouped together.
One to many Biometric Didn't Match scans, without a subsequent Biometric Enrolled scan	Patient Not Found	Multiple failed authentications with the same search criteria, are performed on the same machine by the same user, without being followed by a Biometric Enrolled or Biometric Matched scan. Each authentication attempt must occur with 5 minutes of the prior authentication attempt in order to be grouped together.
One to many Biometric Didn't Match scans followed by an opt-out	Opt-Out	Multiple failed authentications with the same search criteria, are performed on the same machine by the same user, followed by an opt-out with demographics that match the search criteria. The opt-out must occur within 15 minutes of the last Biometric Didn't Match scan in order to be grouped together.

Interactions and Opt-outs

For the File Upload method of calculating utilization, Imprivata PatientSecure includes the ability to decide whether photo-only opt-outs and patient opt-outs will be counted as part of the above equation.

The ability to count patient opt-outs as part of PatientSecure interactions relies on the Opt-out Tracking setting being enabled.

Opt-out Tracking enabled	Opt-out Tracking disabled
Adds Total opt-outs to the equation above: where Total opt-outs= Photo-Only + Patient Opt-outs So that the equation is now: (Patients Found + Patients Not Found + Patients Enrolled + Total Opt-outs) Registrations	The equation remains the same as above: (Patients Found + Patients Not Found + Patients Enrolled + Photo-Only) Registrations
