We piloted large\u2010scale group pre\u2010test GC with up to 50 patients per group and compared this to a traditional one\u2010on\u2010one approach. Patients referred to the British Columbia (BC) Cancer Hereditary Cancer Program were eligible if they had: (a) family history meeting our program's referral criteria; (b) no relevant personal history of cancer; (c) no prior genetic testing in the family; and (d) no living testable relative in BC. Patient\u2010reported outcome measures included: (a) Genetic Counselling Outcome Scale (GCOS) prior to pre\u2010test GC (T1) and at 4\u00a0weeks post\u2010test GC (T2); (b) Satisfaction Survey after pre\u2010test GC; and (c) the Multidimensional Impact of Cancer Risk Assessment (MICRA) for patients undergoing testing (4\u00a0weeks after post\u2010test GC). In total, 391 patients underwent GC, 184 by group and 207 by one\u2010on\u2010one appointments. Between May 2018 and May 2019, 6 pre\u2010test group sessions were conducted (median number of patients per group\u00a0=\u00a028; range 15\u201348). 8% of patients (<jats:italic>n<\/jats:italic>\u00a0=\u00a032) declined large group GC due to personal preference for one\u2010on\u2010one GC. There were no statistically significant differences in MICRA and GCOS survey results when comparing the pre\u2010test large group versus traditional pre\u2010test one\u2010on\u2010one models (based on 3 MICRA subscales: <jats:italic>p<\/jats:italic>\u00a0=\u00a00.063, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.612, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.842; and GCOS <jats:italic>p<\/jats:italic>\u00a0=\u00a00.169). Overall, the large group pre\u2010test counseling approach was more time\u2010efficient with 15\u201348 patient group sessions conducted over a mean duration of 80\u00a0min as compared to 42\u00a0min per patient with the traditional one\u2010on\u2010one GC model. Large\u2010scale group GC was feasible and acceptable to patients and represents a novel streamlined model for GC to enable timely access to cancer genetic services.<\/jats:p>","DOI":"10.1002\/jgc4.1512","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T10:50:51Z","timestamp":1633085451000},"page":"459-469","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Large\u2010scale
