Parkinson disease (PD) patients undergoing lumbar surgery for degenerative conditions have increased length of stay (LOS) and costs when compared to patients without PD, according to a recent study. Researchers examined the Nationwide Inpatient Sample from 2002 to 2011. Patients were included for study based on ICD-9-CM procedural codes for lumbar spine surgery and substratified to degenerative diagnoses. Incidence and baseline patient characteristics were determined. Multivariable analysis was performed to determine independent risk factors increasing incidence of lumbar fusion revision in PD patients. They found:
- PD patients account for 0.9% of all degenerative lumbar procedures.
- At baseline, PD patients are older (70.7 vs 58.9) and more likely to be male (58.6% male).
- Mean LOS was increased in PD patients undergoing lumbar fusion (5.1 days vs 4.0 days) and lumbar fusion revision (6.2 days vs 4.8 days).
- Costs were 7.9% higher for lumbar fusion and 25.2% higher for lumbar fusion revision in PD patients.
- Multivariable analysis indicates that osteoporosis, fluid/electrolyte disorders, blood loss anemia, and insurance status are significant independent predictors of lumbar fusion revision in patients with PD.
