After the Haiti earthquake of 2010, Sahana was used as a registry of the nearly 700 organizations responding, tracked almost 10,000 requests for assistance and information collected by Project 4636, provided the most accurate and complete registry of the 162 operating hospitals and medical facilities along with bed availability and status, and aggregated 41 data layers from various sources onto one situation map. More than 230 registered users entered data into the system, which was accessed by over 8,600 visitors. The site was used daily by dozens of responding agencies in the first month of the disaster response.
