Utility of Electronic Medical Record for Recruitment in Clinical Research: from Rare to Common Disease

Abstract: Background Recruitment for clinical trials is a major challenge. Movement disorders, which do not have associated diagnostic laboratory tests, may be especially prone to inaccuracy in coding. Our objective was to evaluate the accuracy of diagnostic codes such as cervical dystonia (CD) and PD in an electronic medical record. Methods Retrospective chart review was performed to confirm the ICD-9 diagnoses of PD, CD and diabetes mellitus type 2 (DM-2), using published clinical diagnostic criteria (PD, CD) and he… Show more

“…Three were from the UK[20,21,28], six from mainland Europe[12,13,18,2527], eight from the USA[1417,19,2224], and one from Canada[11]. There were 12 PPV estimates and two sensitivity estimates from hospital data[1119], two PPV and 10 sensitivity estimates from mortality data[12,2528], two PPV estimates from primary care data[20], four PPV estimates from prescription data[11,17,21] and seven PPV estimates and two sensitivity estimates from combining datasets from different sources[12,13,2224]. There were no sensitivity estimates from primary care or prescription data.…”
