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

To implement provisions of the 21st Century Cures Act that address information blocking, federal regulations mandated that health systems provide patients with immediate access to elements of their electronic health information, including imaging results. The purpose of this study was to compare patient access of radiology reports before and after implementation of the information-blocking provisions of the 21st Century Cures Act. This retrospective study included patients who underwent outpatient imaging examinations from January 1, 2021, through December 31, 2022, at three campuses within a large health system. The system implemented policies to comply with the 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 being released immediately after report finalization after implementation. Data regarding patient report access in the portal and report acknowledgment by the ordering provider in the EMR were extracted and compared between periods. The study included reports for 1,188,692 examinations in 388,921 patients (mean age, 58.5 ± 16.6 [SD] years; 209,589 women, 179,290 men, eight nonbinary individuals, and 34 individuals for whom sex information was missing). A total of 77.5% of reports were accessed by the patient before implementation versus 80.4% after implementation. The median time from report finalization to report release in the patient portal was 36.0 hours before implementation versus 0.4 hours after implementation. The median time from report release to first patient access of the report in the portal was 8.7 hours before implementation versus 3.0 hours after implementation. The median time from report finalization to first patient access was 45.0 hours before implementation versus 5.5 hours after implementation. Before implementation, a total of 18.5% of reports were first accessed by the patient before being accessed by the ordering provider versus 44.0% after implementation. After implementation, the median time from report release to first patient access was 1.8 hours for patients with age younger than 60 years old versus 4.3 hours for patients 60 years old or older. After implementation of institutional policies to comply with 21st Century Cures Act information-blocking provisions, the length of time until patients accessed imaging results decreased, and the proportion of patients who accessed their reports before the ordering provider increased. Radiologists should consider mechanisms to ensure timely and appropriate communication of important findings to ordering providers.
