Using Emails and Personalized Phone Calls to Increase Affordable Care Act Marketplace Enrollment Among Households Losing Medicaid
NCT05327712 · View on ClinicalTrials.gov ↗
Study Summary
Since its passage in 2010, the Affordable Care Act (ACA) has helped reduce the uninsured rate to record lows, but changes in insurance coverage over time, known as churn, remain a concern. A recent survey found that nearly 25 percent of respondents reported a change in coverage over the previous twelve months. Among the most common reasons for churn is the loss of Medicaid eligibility, placing low-income populations at risk of a coverage gap. To date, little evidence exists on effective strategies states can use to facilitate Medicaid to Marketplace coverage transitions, an issue that has become more pressing amid projections that upwards of 15 million people could lose Medicaid eligibility once the COVID-19 public health emergency expires. To address this gap and to inform Marketplace administrators, during a Special Enrollment Period (SEP) in 2017 in California's ACA Marketplace, we conducted a randomized controlled trial to examine the effect of email reminders, personalized telephone outreach, as well as the combination of the two forms of outreach on ACA enrollment among households who recently lost Medicaid and became eligible for subsidized Marketplace coverage. During the SEP at the end of August 2017, the investigators randomly assigned households to one of four arms based on the last digit of their household identifier: a control group assigned to receive no outreach beyond an initial eligibility determination notice; an email-only group assigned to receive an initial eligibility determination plus email reminders about signing up for marketplace coverage; a phone-only group assigned to receive an initial eligibility determination plus a phone call offering enrollment assistance from a service center representative (SCR); a phone + email group assigned to receive an initial eligibility determination, email reminders about signing up for marketplace coverage and a phone call offering enrollment assistance.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05327712
The ClinicalTrials.gov registry entry for NCT05327712 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 2,173 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Office of Evaluation Sciences, which has 2 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Health Behavior appearing as the primary indexed condition, and to 4 interventions — of which Control group is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05327712 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
