IMproved PRactice Outcomes and Value Excellence in Colposcopy (IMPROVE-COLPO)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02185599
Recruitment Status : Completed
First Posted : July 9, 2014
Last Update Posted : March 13, 2020

DySIS Medical Inc.

Brief Summary:

The study will observe and quantify shifts in colposcopy practice and outcome improvements in U.S. community-based cervical screening colposcopy examinations after the introduction of the DySIS colposcope with Advanced Cervical Scan.

The study will collect colposcopy data across multiple sites in two arms; a prospective arm, with DySIS being used for the examination and a retrospective arm, with data retrieved from patient charts.

Condition or disease Intervention/treatment
High Grade Cervical Intraepithelial Neoplasia Device: DySIS

Detailed Description:

Each site will contribute data to both arms; the study will collect data on demographics, disease yield, number of biopsies and treatment decisions. Study subjects will receive standard of care procedures and management.

Prospective data will be collected at colposcopy examinations performed using the DySIS digital colposcope on consecutive patients that have been referred for colposcopy after a positive screening test. Retrospective data on colposcopy examinations performed using a standard colposcope will be collected from patient medical records, to capture standard practice to-date as a control for comparisons. The retrospective data will be collected from consecutive examinations performed by the providers participating in the prospective arm and for the preceding year.
