CLAUSTROPHOBIA: A PROXY FOR PSYCHOLOGICAL DISTRESS IN BACK PAIN PATIENTS

Britspine, British Scoliosis Society (BSS), Society for Back Pain Research (SBPR), British Association of Spine Surgeons (BASS)



Abstract

Compare the prevalence of psychological distress in claustrophobic patients compared with a non-affected group, together with determination of presenting disability and overall intervention rates.

Retrospective case notes review.

33 patients (13 males) all requiring MRI scan under sedation for claustrophobia (Group 1) were compared with an age and sex matched cohort that had MRI without sedation (Group 2). Both groups were drawn from the same chronic back clinic. Average age in both groups was 54 years (range 27-79 years). Both groups had standard conservative therapy, together with psychometric evaluation.

Primary: Zung Depression Index (ZDI), Modified Somatic Perception Questionnaire (MSPQ). Secondary: Oswestry Disability Index (ODI), intervention rates (surgery, injections and physiotherapy sessions)

Comparison of means -

22 patients (66.7%) in Group 1 were discharged after their MRI with no intervention compared to 7 patients (21.2%) in Group 2.

Claustrophobic patients with back pain showed higher levels of depression than non-claustrophobic patients, with a greater prevalence of psychological distress. Disability however was the same. The majority of claustrophobic patients had no intervention, with a lower rate than their non-claustrophobic peers. Claustrophobia is a proxy for psychological distress and should be considered in the overall evaluation of chronic back patients.
