{"doi":"10.1093/jamia/ocaa245","title":"Assessing the practice of data quality evaluation in a national clinical data research network through a systematic scoping review in the era of real-world data","abstract":"OBJECTIVE: To synthesize data quality (DQ) dimensions and assessment methods of real-world data, especially electronic health records, through a systematic scoping review and to assess the practice of DQ assessment in the national Patient-centered Clinical Research Network (PCORnet). MATERIALS AND METHODS: We started with 3 widely cited DQ literature-2 reviews from Chan et al (2010) and Weiskopf et al (2013a) and 1 DQ framework from Kahn et al (2016)-and expanded our review systematically to cover relevant articles published up to February 2020. We extracted DQ dimensions and assessment methods from these studies, mapped their relationships, and organized a synthesized summarization of existing DQ dimensions and assessment methods. We reviewed the data checks employed by the PCORnet and mapped them to the synthesized DQ dimensions and methods. RESULTS: We analyzed a total of 3 reviews, 20 DQ frameworks, and 226 DQ studies and extracted 14 DQ dimensions and 10 assessment methods. We found that completeness, concordance, and correctness/accuracy were commonly assessed. Element presence, validity check, and conformance were commonly used DQ assessment methods and were the main focuses of the PCORnet data checks. DISCUSSION: Definitions of DQ dimensions and methods were not consistent in the literature, and the DQ assessment practice was not evenly distributed (eg, usability and ease-of-use were rarely discussed). Challenges in DQ assessments, given the complex and heterogeneous nature of real-world data, exist. CONCLUSION: The practice of DQ assessment is still limited in scope. Future work is warranted to generate understandable, executable, and reusable DQ measures.","journal":"Journal of the American Medical Informatics Association","year":2020,"id":55264,"datarank":3.325115653589752,"base_score":4.564348191467836,"endowment":4.564348191467836,"self_citation_contribution":0.6846522287201755,"citation_network_contribution":2.6404634248695764,"self_endowment_contribution":0.6846522287201755,"citer_contribution":2.6404634248695764,"corpus_percentile":93.3240504370697,"corpus_rank":864,"citation_count":95,"citer_count":90,"citers_with_citation_signal":61,"citers_with_endowment":61,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.7691,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":285592,"name":"Tianchen Lyu","orcid":"0000-0002-0981-3847","position":1,"is_corresponding":false},{"id":287216,"name":"Alexander Loiacono","orcid":null,"position":2,"is_corresponding":false},{"id":287217,"name":"Tonatiuh Mendoza Viramontes","orcid":null,"position":3,"is_corresponding":false},{"id":285593,"name":"Gloria Lipori","orcid":"0000-0001-5616-2701","position":4,"is_corresponding":false},{"id":263949,"name":"Yi Guo","orcid":"0000-0003-0587-4105","position":5,"is_corresponding":false},{"id":285007,"name":"Yonghui Wu","orcid":"0000-0002-6780-6135","position":6,"is_corresponding":false},{"id":285001,"name":"Mattia Prosperi","orcid":"0000-0002-9021-5595","position":7,"is_corresponding":false},{"id":263950,"name":"Thomas J.
