A large inpatient database was used to identify elderly patients who underwent posterior surgery for cervical myelopathy.
Prolonged length of stay (PLOS) was defined as stay beyond 6 days in this study.
Predictive factors for PLOS included alcohol abuse, deep vein thrombosis, myocardial infarction, pneumonia, and others.
PLOS was associated with significantly higher mortality rates and total hospital charges compared to the control group.
