About
This 2-arm prospective, randomized, controlled clinical trial compared outcomes of telephone genetic counseling (intervention) versus in-person genetic counseling (control) in an underserved, multilingual patient population referred for cancer genetic counseling at two North Texas safety-net hospitals.
The main question[s] it aims to answer are:
- Is telephone genetic counseling equal to in-person genetic counseling in the patient reported outcomes? Cancer genetics knowledge, attitude towards GT, and informed choice as well as GC-specific empowerment.
- Is telephone genetic counseling-based clinical outcomes the same as in-person genetic counseling for visit completion and testing rates? Participants will be randomized to either in-person or telephone genetic counseling arm and complete standard of care genetic counseling visit process where testing is offered. Both arms will complete a series of surveys to assess the outcomes of interest.
Full description
The overarching goal of this pilot prospective randomized controlled study is to compare patient-reported and clinical operations outcomes between in-person genetic counseling (IPGC - control) and telephone-based genetic counseling (TGC - intervention) in an indigent English or Spanish-speaking population seeking genetic counseling for hereditary cancer syndromes to create a framework for effective and efficient genetic service delivery in these populations nationally. General genetic education and principles will be conveyed through a standard genetic counseling session including a pre-test education video in both the TGC and IPGC arms. The primary project objectives are to compare the following outcomes between the IPGC and TGC study arms. Aim 1: Patient reported outcomes - A. Patient satisfaction with genetic counseling visit; B. Knowledge of basic principles of cancer genetics and implications of genetic testing for personal healthcare and relatives. Secondary objectives for this aim are: 1. Patient ability to make informed choice; and 2. Genetic counseling-specific empowerment outcomes. Aim 2: Clinical outcomes - visit completion rate; Secondary objectives are: 1. Genetic testing completion rate; and 2. Genetic testing cancelation/failure rate. Investigators hypothesize that patients in the TGC arm will not have significant differences in knowledge, satisfaction, informed choice or genetic counseling-specific empowerment compared to the IPGC arm. Investigators also expect significantly increased visit completion rate and lower test completion rate in the TGC arm compared to the IPGC arm, but no significant difference in sample failure rate.
