Hospital name comes from three sources according to the following precedence:

• Information may be collected and updated as the result of direct communications with hospitals, news items, etc. Such information has highest precedence over other sources.
• Information may be collected or updated directly from a hospital's website or from a system's website.
• Information for hospitals without websites may be taken from their most recent Medicare cost report and/or the Medicare Provider of Services file. (Data for these hospitals are updated quarterly as new versions of these files become available. Data from these sources are only used when information is not available from a website or through direct communications.)

Numbers of staffed beds are taken from a hospital's most recent Medicare cost report (W/S S-3, Part I, column 2). Cost report instructions define staffed beds as, "the number of beds available for use by patients at the end of the cost reporting period. A bed means an adult bed, pediatric bed, birthing room, or newborn bed maintained in a patient care area for lodging patients in acute, long term, or domiciliary areas of the hospital. Beds in labor room, birthing room, postanesthesia, postoperative recovery rooms, outpatient areas, emergency rooms, ancillary departments, nurses' and other staff residences, and other such areas which are regularly maintained and utilized for only a portion of the stay of patients (primarily for special procedures or not for inpatient lodging) are not termed a bed for these purposes." Note that beds by unit are reported elsewhere on the Profile and the Departments reports.

• General Medical/Surgical Beds are the beds used for routine care.
• Special Care Beds include Intensive Care Units, Coronary Care Units, etc.
