Use of a hospital practice management system to provide initial data for a pediatric immunization registry.
An ongoing challenge in the creation of clinical information systems is the capture of structured clinical information from health care providers while avoiding duplicate data recording. Because immunizations are reimbursable medical procedures, practice management systems that already capture such procedures may be used as a source of clinical data for information systems. We instituted a method for capturing such data on one campus of a multi-institution pediatric immunization registry. We measured the effectiveness of this capture by comparing it to manual audits of selected paper charts over 26 months. Of the immunizations documented by chart audit, 39.69% were captured by the practice management system. Of those not captured, we estimate that a substantial portion were immunizations administered elsewhere and as a result not submitted as a claim through the practice management system. In turn, this was affected by a rate of patient disengagement from primary care of 49%. We discuss the issues associated with using claims data to capture clinical information in the setting of an immunization registry and review possible explanations for this data capture rate.
