Diagnostic delays in infective discitis – an unresolved problem
摘要
A retrospective study.
ObjectivesNeurological deficits occur in 1/3 of spinal infection cases. Non-specific symptoms can lead to delays in diagnosis. This study reviews outcomes and the timeliness of diagnosis in patients with spinal infection who sustained subsequent spinal cord impairment.
SettingAll 40 patients admitted to The Princess Royal Spinal Injuries Centre, Sheffield, UK, between 2016–2018 for rehabilitation for spinal cord impairment secondary to spinal infection.
ResultsThe average age was 58.6 years (31–85; SD 13.1) with 24 (60%) being male. 36 (90%) had native infections and 3 (7.5%) were acquired post-operatively (1 (2.5%) unknown). 7 patients had been intravenous drug users (17.5%). 50% (20) had previously sought medical attention for the same symptoms. There were long intervals to suspected diagnosis and to MRI (range 0–30 days). 15 (37.5%) patients deteriorated neurologically following admission to hospital; 8 were taking antibiotics at the time of deterioration. None of the patients had normal C-reactive protein levels at presentation. 7 (17.5%) sustained complete spinal cord impairment. 27 (67.5%) were discharged as wheelchair users.
ConclusionsWhilst the majority of patients responded to rehabilitation interventions, they were left with residual life changing disabilities. Among those requiring rehabilitation, delays in diagnosis appear to frequently occur pre-hospital. This could be attributed to a low index of suspicion in the community. Some deteriorated neurologically despite antibiotics. Close neurological monitoring of those suspected or confirmed to have a diagnosis of spinal infection is appropriate. There should be a low threshold for the use of inflammatory markers when investigating back pain.
