Clinical features and inpatient rehabilitation outcomes of infection-related myelopathy

Study design: This was a retrospective cohort study. Objectives: The objectives of this study were to determine clinical features of infection-related myelopathy (IRM) and functional outcomes compared with other nontraumatic and traumatic myelopathies. Setting: US academic inpatient rehabilitation unit. Methods: This was a 16-year retrospective review of patients with myelopathy discharged from inpatient rehabilitation between 1 January 1995 and 31 December 2010. Patients comprised three injury groups: IRM, nontraumatic myelopathy (NTM) and traumatic spinal cord injury (TSCI). Information collected includes demographic characteristics, functional data, length of stay, injury completeness and discharge destination. Primary outcome measures were change in Functional Independence Measure (FIM) and daily FIM change. For IRM, data were collected regarding injury characteristics, risk factors, presenting symptoms, neurologic impairment level and treatment. Results: Of the 1601 patients, 40 (2.5%) had IRM, 1105 (69.0%) had NTM and 456 (28.5%) had TSCI. IRM mean (s.d.) age was 58.6 (15.7) years (male gender, 72.5%). The majority in each group had incomplete injuries. IRM had longer lengths of stay ( P
