Patients Now See Test Results Before Doctors Can Explain Them

A federal mandate that took effect five years ago rewired how Americans receive medical information, creating a portal-first era in which a diagnosis can arrive on a smartphone screen before a physician has had the chance to make a single phone call.

The legal trigger was the 21st Century Cures Act's information blocking prohibition, which went into effect on April 5, 2021. Under the Office of the National Coordinator for Health Information Technology's Cures Act Final Rule, healthcare providers became legally required to give patients rapid, free, and full access to test results, medication lists, referral information, and clinical notes, all in electronic format, without delay. Blocking patients from their own records became illegal, enforceable by fines against hospitals and clinicians. On October 6, 2022, the rule expanded further, extending access to all Electronic Health Information beyond the initial dataset.

Patients, it turns out, largely want it this way. A study of 8,000 patients who accessed results through an online portal found that more than 95% wanted to keep receiving them immediately, a figure that held even among those who had received abnormal findings. A March 2023 study co-led by researchers at UT Southwestern Medical Center in Dallas reached a similar conclusion: patients overwhelmingly prefer results as soon as they are available online, even before speaking with their doctor.

But preference and emotional readiness are not the same thing. Research shows that the automatic release of abnormal results through patient portals can produce significant emotional distress. Even normal results generate confusion and stress, given the difficulty many patients face interpreting complex medical terminology. One counterintuitive finding from the research: the anxiety of waiting for results frequently exceeds the distress of actually receiving them, even when the news is bad, making the patient portal, where results can appear without warning at any hour, a particularly charged environment.

Healthcare providers have felt the shift as well. A study at Vanderbilt University Medical Center in Nashville compared unsolicited patient complaints in the year before the information blocking rule took effect with those logged more than a year after. Complaints related to communication, documentation, treatment, and diagnosis totaled 5,473 in the post-implementation period, a rise over the preceding baseline. In mental health settings, the effects were more acute: 55% of providers reported that patients experienced significant distress after accessing their portal, and 69% said patients were asking more questions as a direct result of reading their clinical notes online.

Research published in the Journal of Surgical Research in 2023 by Peter D. Congelosi, Mark A. Eid, and Meredith J. Sorensen of Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, found that clinicians' initial concerns about the rule's effect on patient anxiety and quality of care had somewhat eased over time, but the authors called for deeper investigation into how immediate electronic access has reshaped medical practice.

The complications extend beyond the portal itself. A February 2025 study led by the University of Sydney, published in JAMA Network Open, examined nearly 1,000 posts across Instagram and TikTok about five controversial medical screening tests. Influencers on those platforms were found to be promoting overwhelmingly misleading information about medical tests to an audience of nearly 200 million followers. For patients already interpreting results without clinical guidance, the social media environment adds another layer of potential confusion.

The 21st Century Cures Act established data access as a patient right. The research accumulating in its wake raises a harder question: whether access without adequate interpretive support empowers patients, or whether the gap between receiving a result and understanding it has become one of American healthcare's most consequential blind spots.
