Patient Access of Their Radiology Reports Before and After Implementation of 21st Century Cures Act Information-Blocking Provisions at a Large Multicampus Health System.

Background: To implement provisions of the 21st Century Cures Act addressing information blocking, federal regulations mandated that health systems provide patients with immediate access to elements of their electronic health information, including imaging results. Objective: To compare patient access of radiology reports before and after implementation of the information-blocking provisions of the 21st Century Cures Act. Method: This retrospective study included patients who underwent outpatient imaging examinations from January 1, 2021, to December 31, 2022 at three campuses within a large health system. The system implemented policies to comply with Cures Act information-blocking provisions on January 1, 2022. Imaging results were released in patient portals after a 36-hour embargo period before implementation, versus immediately upon report finalization after implementation. Data regarding patient report access in the portal and ordering provider report acknowledgment in the EMR were extracted and compared between periods. Results: The study included reports for 1,188,692 examinations in 388,921 patients (mean age, 58.5±16.6 years; 209,589 women, 179,290 men, 8 nonbinary, 34 missing sex information). A total of 77.5% of reports were accessed by the patient before implementation, versus 80.4% after implementation. Median time from report finalization to report release in the patient portal was 36.0 hours before implementation versus 0.4 hours after implementation. Median time from report release to first patient access in the portal was 8.7 hours before implementation versus 3.0 hours after implementation. Median time from report finalization to first patient access was 45.0 hours before implementation versus 5.5 hours after implementation. A total of 18.5% of reports were first accessed by the patient before the ordering provider before implementation, versus 44.0% after implementation. After implementation, median time from report release to first patient access was 1.8 hours for patients with age <60 years versus 4.3 hours for patients with age ≥60 years. Conclusion: After implementing institutional policies to comply with Cures Act information-blocking provisions, the time for patients to access imaging results decreased, and the proportion of patients who accessed their reports before the ordering provider increased. Clinical Impact: Radiologists should consider mechanisms to ensure timely and appropriate communication of important findings to ordering providers.
