A UCSF-led deep dive into more than 16,000 contacts to a clinician-staffed abortion and miscarriage hotline finds demand was already surging well before the Supreme Court weighed in on Dobbs. Use of the Miscarriage & Abortion Hotline climbed sharply between mid-2022 and mid-2023, ultimately rising about 210%, and the spike started ahead of the 2022 decision. The pattern points to people increasingly seeking confidential, real-time medical advice outside brick-and-mortar clinics as access tightened across the country.
Study methods and headline numbers
The peer-reviewed study tracked 16,429 unique contacts to the M+A Hotline from June 24, 2021, through June 24, 2023. Researchers counted 4,009 pre-Dobbs contacts and 12,420 post-Dobbs contacts, an overall increase of roughly 210% over the two-year window, according to the authors. The full analysis appears in The Lancet Regional Health – Americas.
Hotline demand climbed before Dobbs
The curve was already bending upward before the Supreme Court ruling. The research team found about a 10% monthly increase in hotline use in states that did not go on to enact abortion bans, while states that later adopted restrictions saw an additional 7% monthly bump. Average monthly contacts in states that eventually imposed bans rose from about 183 before Dobbs to roughly 640 after, compared with an increase from about 125 to 315 in states that did not enact bans, as reported by MedicalXpress.
Researchers: barriers predated the ruling
UCSF associate professor Jennifer Karlin, a senior author on the paper, said the numbers undercut the idea that access problems emerged only after Dobbs. Instead, she said, they highlight mounting barriers that were already pushing people toward alternative routes for care. “Patients are continuing to find ways to access care, even in highly restrictive environments,” Karlin said in the UCSF news release.
UCSF expands clinician hotline support
Karlin has led the UCSF Reproductive Health Hotline (ReproHH) since 2025. The service is a free, confidential clinician-to-clinician line that offers on-demand guidance on contraception, early pregnancy, and abortion care. According to ReproHH, the model shows how academic health systems are trying to plug gaps left by clinic closures and a shifting patchwork of state laws.
What it means nationally
Public health researchers say the hotline data offer a rare look at how patients seek medical support outside traditional health care settings as access grows more fragmented. They note that hotlines are emerging as a crucial safety-net for people navigating complex and sometimes hostile policy landscapes. Related studies and resources are cataloged in national reproductive health research repositories, including ANSIRH, which tracks work on abortion access and restrictions.
California angle
California has moved to bolster these alternative access paths. State initiatives and contracts have helped fund clinician hotlines and related services that support patients both inside and outside California. The California Health Care Access and Information Office describes the state’s Reproductive Health Care Access Initiative, which includes funding streams to expand practical support and hotline capacity, on its program page at HCAI.
The full study is available in The Lancet Regional Health – Americas, and the authors say the findings highlight growing unmet need as reproductive care splinters across the United States. For clinicians and policymakers, the paper casts hotlines as both a critical stopgap for patients and a warning flare that more durable, system-wide access solutions are urgently needed.
