Jb. Pollard et al., USE OF OUTPATIENT PREOPERATIVE EVALUATION TO DECREASE LENGTH OF STAY FOR VASCULAR-SURGERY, Anesthesia and analgesia, 85(6), 1997, pp. 1307-1311
Interventions that decrease perioperative length of stay can result in
considerable cost-savings. This study assesses the impact of same-day
admission using outpatient preoperative evaluation on the lengths of
stay and hospital costs for patients who underwent carotid endarterect
omy (CEA) or lower extremity revascularization (LER). Patient characte
ristics and length of stay were compared for two 1-yr periods before a
nd after outpatient preoperative evaluation had been implemented. Ther
e were no significant differences before and after the initiation of o
utpatient preoperative evaluation in the CEA and LER groups in mean ag
e and ASA physical status distributions. The average preoperative leng
th of stay decreased significantly from 7.0 to 1.9 days in the CEA gro
up and from 9.0 to 2.8 days in the LER group. This reduction in the le
ngth of stay was associated with a cost-savings of $900 per patient an
d did not have an adverse effect on patient outcome. We conclude that
outpatient preoperative evaluation clinics reduce the cost and length
of stay in vascular surgery patients. Implications: We found that outp
atient preoperative evaluation and same-day admission were associated
with a decrease of 4.5 days in the preoperative length of stay for car
otid endarterectomy and lower-extremity revascularization. This was no
t accompanied by increased mortality and led to hospital cost-savings
of approximately $900 per patient.
