The general composition ofthe patient population Is roughly 76 years of age and the majority female ("53%). During any of the patient admissions, a small number of the patients required ventilation during their admittance to the hospital (SJ4.5%, p=.119). The mean Charlson Comorhidity Score across both the pre and postintervention groups was 0.48 indicating a low number of comorbidities for the population as a whole. Similarly, the mean length of stay (L05) between both intervention periods is the same at 5.55 days (p=.376). The mean total hospital payment between the pre and post-intervention groups differed only slightly, $18,738 and $18,152. respectively (p=.057). The percentage of patients discharged to a nursing home differed by 0.6% between the pre and post-intenlen on groups (limit-16.4%, p=.735), but this difference also was not statistically signicant. The only statistically signicant difference between the two intervention periods is the number of days until readmission (129.1- 147.7. p=.ooo).
