Population Genomic Screening for Three Common Hereditary Conditions : A Cost-Effectiveness Analysis.
Gregory F Guzauskas et al. Ann Intern Med 2023 5

The cost-effectiveness of screening the U.S. population for Centers for Disease Control and Prevention (CDC) Tier 1 genomic conditions is unknown. We estimated the cost-effectiveness of simultaneous genomic screening for Lynch syndrome (LS), hereditary breast and ovarian cancer syndrome (HBOC), and familial hypercholesterolemia (FH). We found that population genomic screening with a restricted panel of high-evidence genes is likely to be cost-effective in U.S. adults younger than 40 years if the testing cost is relatively low and probands have access to preventive interventions.

Offering genetic testing at the point of care may increase uptake
Medical Xpress, May 3, 2023

Genetic testing for hereditary cancers, such as breast, colon, pancreatic, and ovarian cancer, helps at-risk individuals understand their familial risk for these diseases and make informed decisions about next steps in care. But fewer than 20 percent of at-risk patients utilize this testing, and even fewer engage in genetic counseling after referral, often due to clinical workflow challenges or barriers to care. A new study researchers haveidentified a streamlined approach in clinical settings that may help advance these efforts by simplifying the process of identifying hereditary cancer risk and determining subsequent care.

Development and Evaluation of a Telephone Communication Protocol for the Delivery of Personalized Melanoma Genomic Risk to the General Population.
Georgina L Fenton et al. J Genet Couns 2017 12 (2) 370-380

This study aimed to develop an online educational program for using PRS for breast and ovarian cancer risk-assessments and evaluate the impact on genetic healthcare providers’ (GHP) attitudes, confidence, knowledge, and preparedness. The educational program comprised of an online module covering theoretical aspects of PRS, and a facilitated virtual workshop with pre-recorded roleplays and case discussions. Data were collected in pre-and post-education surveys.

Implementing digital systems to facilitate genetic testing for hereditary cancer syndromes: An observational study of four clinical workflows
C Wang et al, Genetics in Medicine, February 10, 2023

This study examined the uptake of genetic counseling and testing following the use of a digital cancer genetic risk assessment program, implemented at 27 health care sites in 10 States using one of four clinical workflows: 1) traditional referral, 2) point-of-care scheduling (POC-S), 3) point-of care counseling/telegenetics (POC-C), and 4) point-of-care testing (POC-T). In 2019, 102,542 patients were screened and 33,113 (32%) were identified as high risk and meeting National Comprehensive Cancer Network (NCCN) genetic testing criteria for Hereditary Breast and Ovarian Cancer, Lynch syndrome or both. Among those identified at high risk, 5147 (16%) proceeded with genetic testing. Genetic counseling uptake was 11% among sites with workflows that included seeing a genetic counselor prior to testing.
