Chapter 3. Characteristics of Participating Hospitals

2011 User Comparative Database Report

This chapter presents information about the distribution of database hospitals by bed size, teaching status, ownership and control, and geographic region. Although the hospitals that voluntarily submitted data to the database do not constitute a statistically selected sample, the characteristics of these hospitals are fairly consistent with the distribution of hospitals registered with the American Hospital Association (AHA). The characteristics of database hospitals by bed size, teaching status, ownership and control, and geographic region are presented in the following tablesiv and are compared with the distribution of AHA-registered hospitals included in the 2010 AHA Annual Survey of Hospitals.v

Highlights

  • Database hospitals represent a range of bed sizes and geographic regions.
  • Most database hospitals are nonteaching (66 percent) and non-government owned (voluntary/nonprofit or proprietary/investor owned) (80 percent).
  • Overall, the characteristics of the 1,032 database hospitals are fairly consistent with the distribution of hospitals registered with the American Hospital Association.

Bed Size

Table 3-1 shows the distribution of database hospitals and respondents by hospital bed size. Overall, the distribution of database hospitals by bed size is similar to the distribution of AHA-registered U.S. hospitals. Most of the database hospitals (63 percent) have fewer than 200 beds, which is similar to but lower than the percentage of AHA-registered U.S. hospitals (74 percent). 

Teaching Status

As shown in Table 3-2, similar to the distribution of AHA-registered hospitals, most database hospitals were nonteaching. However, there was a smaller percentage of nonteaching hospitals in the database (66 percent) compared with AHA-registered hospitals (76 percent). 

Ownership and Control

As shown in Table 3-3, most database hospitals were non-government owned (80 percent), which is similar to the distribution of AHA-registered U.S. hospitals. 

Geographic Region  

Table 3-4 shows the distribution of database hospitals by AHA-defined geographic regions.vi The largest percentages of database hospitals are from the East North Central region (25 percent) and the South Atlantic/Associated Territories region (18 percent). 


iv To ensure hospital confidentiality, at least 20 hospitals had to be in a particular breakout category before data would be displayed for that category.
v Data for U.S. and U.S. territory AHA-registered hospitals were obtained from the 2004, 2006, or 2010 AHA Annual Survey of Hospitals Database, © 2010 Health Forum, LLC, an affiliate of the American Hospital Association. Hospitals not registered with the AHA were asked to provide information on their hospital's characteristics such as bed size, teaching status, and ownership.
vi States and territories are categorized into AHA-defined regions as follows:

  • New England: CT, MA, ME, NH, RI, VT
  • Mid-Atlantic: NJ, NY, PA
  • South Atlantic/Associated Territories: DC, DE, FL, GA, MD, NC, SC, VA, WV, Puerto Rico, Virgin Islands
  • East North Central: IL, IN, MI, OH, WI
  • East South Central: AL, KY, MS, TN
  • West North Central: IA, KS, MN, MO, ND, NE, SD
  • West South Central: AR, LA, OK, TX
  • Mountain: AZ, CO, ID, MT, NM, NV, UT, WY
  • Pacific/Associated Territories: AK, CA, HI, OR, WA, American Samoa, Guam, Marshall Islands, Northern Mariana Islands
