title: Correlates of bacterial pneumonia hospitalizations in elders, Texas border.
abstract: BACKGROUND
  Immunization preventable bacterial pneumonia is an Agency for Healthcare Research and Quality (AHRQ) prevention quality indicator of health care. This study explored associations of individual and county correlates with bacterial pneumonia hospitalization rates for elders residing in 32 Texas counties bordering Mexico.
  
  
  METHODS
  We estimated baseline rates from Texas Health Care Information Collection's hospital discharge data for 1999-2001, and population counts from the 2000 U.S. Census.
  
  
  RESULTS
  The rate among the total Texas border population was 500/10,000, three times the national rate. Elders 75+, males, and Latinos had the highest rates. An increase of 1 primary care physician per 1000 population is associated with a decrease in pneumonia-related hospitalization rates by 33%, while each 10% increase in Latinos is associated with a 0.1% rate increase.
  
  
  CONCLUSIONS
  This baseline bacterial pneumonia hospitalization study demonstrates a systematic approach to estimate county rates, a process that could lead to improved outcomes through effective community interventions. Methodology demonstrates how publicly available hospital discharge data can be used by communities to better measure and improve quality of health care.
