About launched February 9, 2012, as a snapshot of online cesarean rate reporting in the United States. Most recently updated in January 2015 [in progress], the site compiles the most current hospital-level data accessible to the public online, whether reported directly by a state’s department of health or gathered from state hospital association web sites via pull-down menus.

The initial goals of the site were to a) show the quality and inaccessibility of information available to the public, b) to assess whether there is public demand for this information and c) to work toward establishing a precedent for hospital data transparency.

This site's sole source of funding is Google Adsense and occasional paid advertisements.


About the Data

The data found on this site are the most current state-by-state information available to the public online (unless otherwise indicated) as of January 2015. 

This site contains tables of total cesarean rates (total cesarean sections divided by total births) and other delivery method data if available. Unless indicated, the data are not risk-adjusted.

States collect hospital in-patient utilization data. These data contain no clinical information, nor do they have patient or physician identifiers. They answer the question of how many times a particular procedure is performed at a facility during a certain period of time and can help illuminate utilization patterns in larger geographic areas.

Caution should be exercised in employing rates derived by small numbers and from small populations.

Most states do not report these numbers directly on their own sites. Disaggregated utilization data are often shared on outside sites in a “hospital compare” type format which require the user to use pull-down menus to access numbers one-by-one. This may affect the accuracy of the information found on this site; for example, if these sites make a change to a number in their database, the percentage here would no longer be correct.

The data on this site are found on publicly accessible web sites. specifically disclaims responsibility for any analyses, interpretations or conclusions.
