ABSTRACT

OBJECTIVES: To describe the clinical impact and lessons learned through implementation of a high sensitivity troponin (hsTn) assay.

BACKGROUND: hsTn assays have received regulatory approval for use in the United States, and healthcare facilities are beginning to adopt these new assays. Questions remain about how to implement them and what effect they may have on demand for cardiovascular services.

METHODS: We conducted a mixed-methods implementation science-based investigation of hsTn adoption at a single academic medical center. We designed the investigation based on the Consolidated Framework for Implementation Research, exploring clinicians' perspectives on intervention characteristics, inner setting, individual characteristics, and process of implementation domains. Focus groups were conducted with clinicians from multiple service lines.

RESULTS: Participants reported that the new hsTn assay did not fundamentally change processes of care such as cardiology consultations or inpatient admissions. Implementation was facilitated by leveraging the electronic medical record to provide useful suggestions for hsTn management at the point-of-care. The use of case-based teaching was considered most effective. Areas of ongoing concern included management of high-risk patients, outpatient follow-up, and feasibility of accelerated diagnostic protocols for early discharge from the emergency department. A decrease in the number of hsTn assays ordered was observed; no change was noted for admissions, cardiology consultations, or noninvasive cardiac imaging.

CONCLUSIONS: A comprehensive educational campaign, based on multidisciplinary collaboration can effectively prepare clinicians for implementation of hsTn. New hsTn assays may not have any substantial effect on acute management of patients with cardiac complaints.
