SAN DIEGO — Patients who experienced greater operative time had double the risk for an extended hospital stay after anterior cervical discectomy and fusion or cervical disc replacement, according to study resulted presented at the Cervical Spine Research Society Annual Meeting.
Aaron J. Greenberg, MD, and colleagues found operative time, abnormal gait and weak narcotic use had a direct influence on length of stay (LOS) after cervical disc replacement (CDR) or anterior cervical discectomy and fusion (ACDF).
“For a 1-hour increase in operating room time, the odds of a longer hospital stay increased by 2.062 times,” Greenberg said, here.
The researchers used data from 1,004 patients in the Bryan/Prestige CDR FDA trial. A total of 518 patients from the investigational arm and 486 patients from the control arm were included in the study. After an initial logistic regression analysis, the researchers found no difference in LOS between patients in the CDR or ACDF groups.
They performed a second initial logistic regression analysis with the CDR and ACDF data combined. Eight independent variables (race, tobacco use, weak narcotic use, arm pain scores, SF-36 mental health scores, preoperative sensory, gait and operative time) were included in the second analysis. Overall, 912 (91%) patients were found to have a 1-day LOS and 92 patients (9%) had a longer than 1-night LOS. Researchers found an abnormal gait increased the odds of a longer LOS by 1.8 and weak narcotic use increased the odds of a longer LOS by 1.7. Greenberg said smoking did not affect LOS in the study. – by Robert Linnehan
