«The Centre for Management Studies of Instituto Superior Técnico (CEGIST) is pleased to announce the seminar “Skilled Physicians and Insured Patients: The Differential Impact of a New Medical Technology Adoption”, by Revathy Surya Narayana (UT Southwestern Medical Center), as part of CEGIST’s seminar series.
This seminar will take place on 15 June at 3.30 p.m. in a hybrid format:
- in-person session at Alameda Campus, in the Department of Engineering and Management’s Meeting Room;
- online, via Zoom
Whether new medical technology broadens access or concentrates gains is central to health policy.
Este seminário analisa a adoção faseada da ablação por campos pulsados (pulsed-field ablation, PFA), uma tecnologia de ablação cardíaca mais rápida aprovada no final de 2023, em hospitais de um grande mercado de cuidados de saúde dos Estados Unidos.
This seminar examines the staggered adoption of pulsed-field ablation (PFA), a faster cardiac-ablation technology approved in late 2023, across hospitals in a large US healthcare market.
Exploiting within-physician variation among electrophysiologists practicing at multiple hospitals, the study finds that PFA availability raises a physician’s ablation volume by 27% and their ablation procedure-mix share by 4.5 percentage points, with no offsetting decline in other procedures. These gains are sharply concentrated. On the supply side, the entire effect accrues to high-volume specialist physicians, with low-volume physicians showing no response. On the demand side, the additional procedures accrue to Medicare and commercially insured patients, while Medicaid and uninsured volumes are unchanged.
The findings show that new medical technology concentrates productivity gains among already-skilled physicians and already-insured patients, widening disparities on both sides of the market.
CEGIST seminars are free to attend and open to the public.»
