Definitions of terms, processes and a minimum dataset for transperineal prostate biopsies: a standardization approach of the G insburg S tudy G roup for E nhanced P rostate D iagnostics

OBJECTIVES: To define terms and processes and agree on a minimum dataset in relation to transperineal prostate biopsy procedures and enhanced prostate diagnostics. To identify the need for further evaluation and establish a collaborative research practice. PATIENTS AND METHODS: A 19-member multidisciplinary panel rated 66 items for their appropriateness and their definition to be incorporated into the international databank using the Research and Development/University of California Los Angeles Appropriateness Method. The item list was developed from interviews conducted with healthcare professionals from urology, radiology, pathology and engineering. RESULTS: The panel agreed on 56 items that were appropriate to be incorporated into a prospective database. In total, 10 items were uncertain and were omitted. These items were within the categories: definitions (n = 2), imaging (n = 1), surgical protocols (n = 2) and histology (n = 5). CONCLUSIONS: The components of a minimum dataset for transperineal prostate biopsy have been defined. This provides an opportunity for multicentre collaborative data analysis and technique development. The findings of the present study will facilitate prospective studies into the application and outcome of transperineal prostate biopsies.
