By using this website you agree to these Terms. If you do not agree, do not use the site.
SurgCalc provides risk estimates and outcome benchmarks derived from published literature and clinical registries to support clinical reasoning and education. Outputs are population-level statistical estimates — not medical advice, not a diagnosis, not a prescription, and not a treatment directive. Treatment decisions must be made by qualified clinicians who retain full professional responsibility. Use of the site does not create a doctor–patient relationship. If you are a patient, discuss any output with your own physician.
These calculators are not a medical device and have not been evaluated, cleared, or approved by the U.S. Food and Drug Administration or any other regulatory authority.
The site and its outputs are provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy or fitness for a particular purpose. Evidence status, model version, data sources, and limitations are disclosed on each calculator page; you are responsible for confirming a model's applicability to your patient population and clinical context before relying on it.
To the maximum extent permitted by law, SurgCalc and Abigail MD, Inc. are not liable for any direct, indirect, incidental, consequential, or special damages, or for any clinical outcome, arising from use of or reliance on this site or its outputs.
The calculators do not request patient identifiers, and you must not enter them. You are responsible for using the site in compliance with HIPAA, your institution's policies, and all applicable laws.
Site content is © Abigail MD, Inc. You may use the calculators for their intended professional and educational purpose; you may not misrepresent the site or its outputs. The underlying models are described in the peer-reviewed publications cited on each page and on the About page.
These Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-laws rules.
We may update these Terms; continued use after an update constitutes acceptance.
