Slide Presentation from the AHRQ 2007 Annual Conference

CAH Variables

• CAH: CAH binary indicator
  • CAHit=1, if hospital i is in CAH status in year t
  • CAHit=0, if hospital i is in PPS status in year t
• CAHmv: moving average CAH variable
  • To examine the relatively long-term effects of CAH conversion
  • CAHmvit=(CAHit+CAHi(t-1)+CAHi(t-2) )/3
  • E.g. CAHmv=0.33 if the hospital is in the first year of conversion
