title: Factors associated with emergency department use among the rural elderly.
abstract: BACKGROUND
  Emergency Department (ED) use among the rural elderly may present a different pattern from the urban elderly, thus requiring different policy initiatives. However, ED use among the rural elderly has seldom been studied and is little understood.
  
  
  OBJECTIVE
  To characterize factors associated with having any versus no ED use among the rural elderly.
  
  
  METHODS
  A cross-sectional and observational study of 1,736 Medicare beneficiaries age 65 and older who live in nonmetropolitan areas. The data are from the 2002 to 2005 Medical Expenditure Panel Survey (MEPS). A logistic regression model was estimated that included measures of predisposing characteristics, enabling factors, need variables, and health behavior as suggested by Anderson's behavioral model of health service utilization.
  
  
  RESULTS
  During a 1-year period, 20.8% of the sample had at least 1 ED visit. Being widowed, more educated, enrolled in Medicaid, with fair/poor self-perceived physical health, respiratory diseases, and heart disease were associated with a higher likelihood of having any ED visits. However, residing in the western and southern United States and being enrolled in Medicaid managed care were associated with lower probability of having any ED visits. While Medicaid enrollees who reported excellent, very good, good, or fair physical health were more likely to have at least 1 ED visit than those not on Medicaid, Medicaid enrollees reporting poor physical health may be less likely to have any ED visits.
  
  
  CONCLUSIONS
  Policy makers and hospital administrators should consider these factors when managing the need for emergency care, including developing interventions to provide needed care through alternate means.
