{"doi":"10.1101/2024.11.22.24317816","title":"Implementing Precision Medicine for Dilated Cardiomyopathy: Insights from The DCM Consortium","abstract":"Background: Clinical genetic evaluation of dilated cardiomyopathy (DCM) is implemented variably or not at all. Identifying needs and barriers to genetic evaluations will enable strategies to enhance precision medicine care. Methods: An online survey was conducted in June 2024 among cardiologist investigators of the DCM Consortium from US advanced heart failure/transplant (HF/TX) programs to collect demographics, training, program characteristics, genetic evaluation practices for DCM, and implementation needs. An in-person discussion followed. Results: Twenty-five cardiologists (28% female, 12% Hispanic, 68% White) participated in the survey and 15 in the discussion; genetics training backgrounds varied greatly. Clinical genetic testing for DCM was conducted by all programs with annual uptake ranging from 5%-70% (median 25%). Thirteen respondents (52%) did not use selection criteria for testing whereas others selected patients based on specific clinical and family history data. Eight (32%) ordered testing by themselves, and the remainder had testing managed mostly by a genetic counselor or others with genetic expertise (16/17; 94%). Six themes were distilled from open-ended responses regarding thoughts for the future and included access to genetics services, navigating uncertainty, knowledge needs, cost concerns, family-based care barriers, and institutional infrastructure limitations. Following an in-person discussion, four areas were identified for focused effort: improved reimbursement for genetic services, genetic counselor integration with HF/TX teams, improved provider education resources, and more research to find missing heritability and to resolve uncertain results. Conclusions: HF/TX programs have implementation challenges in the provision of DCM genetic evaluations; targeted plans to facilitate precision medicine for DCM are needed.","journal":"medRxiv","year":2024,"id":506689,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9044,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":528629,"name":"Hanyu Ni","orcid":"0000-0002-0175-5718","position":1,"is_corresponding":false},{"id":1357797,"name":"P.
