Enhanced profiling period is 1 for period that enhanced profiles were active (beginning October 2005) and 0 previously. Enhanced profiling arm is 1 for facilities randomized to enhanced profiling, and 0 for those randomized to basic profiling. Interaction term is 1 for observations corresponding to programs randomized to enhanced profiling and quarters during enhanced profiling
