BACKGROUND: Patients recovering from decompressive laminectomy without fusion May require assistance with activities of daily living and physical/occupational therapy upon hospital discharge. OBJECTIVE: To examine comorbidities and perioperative characteristics of patients undergoing lumbar decompression for associations with discharge status using a multicenter database. METHODS: A multicenter database was used for this retrospective cohort analysis. Patients admitted from home with degenerative spine disease for lumbar decompression without fusion were included. Thirty-day outcomes and operative characteristics were compared as a function of patient discharge using chi-square and Wilcoxon Rank Sum tests. Multivariable logistic regression was used to determine factors associated with discharge to a nonhome facility. RESULTS: Of the 8627 patients included for analysis, 9.7% were discharged to a nonhome facility. On multivariable analysis, age (85+ vs <65, odds ratio [OR] 13.59), number of levels of decompression (3+ vs 1, OR 1.75), African American race vs Non-Hispanic or Hispanic White (OR 1.87), female vs male gender (OR 1.97), body mass index (BMI) (40+ vs 18.5-24.9, OR 1.74), American Society of Anesthesiologists physical classification status (4 vs 1 or 2, OR 2.35), hypertension (OR 1.29), dependent functional status (OR 3.92), diabetes (OR 1.47), smoking (OR 1.40), hematocrit (<35 vs 35+, OR 1.76), international normalized ratio (=1.3 vs <1.3, OR 2.32), and operative time (3+ h vs <1 h, OR 5.34) were significantly associated with an increased odds of discharge to nonhome facilities. CONCLUSION: Preoperative status and operative course variables can influence discharge disposition in lumbar decompression patients. Identifying specific factors that contribute to a greater likelihood of dismissal to skilled facility or rehabilitation unit can further inform both surgeons and patients during preoperative counseling and disposition planning.
