Abstract
Objectives: The view that patients low back pain presenting with ‘abnormal’ psychometric and poor DRAM scores predict an unsatisfactory surgical outcome is considered controversial. This prospective study was designed to identify if DRAM Scores (Scores of Distress Risk Assessment Method) is a predictive determinant or a reactive instrument in regard to the outcome of Endoscopic Foraminoplasty.
Design: Pre- and postoperative assessment of disability and DRAM at two years.
Subjects: One hundred and eighty-five patients (86 males and 99 females) underwent an Endoscopic Laser Foraminoplasty between April 1997 and November 1998.
Outcome measures: Oswestry Disability Scale, and the Visual Analogue Pain Scale and the DRAM scores. Patients were categorised by their pre-op DRAM score. Kruskal-Wallis analysis of variance and a regression analysis were performed.
Results: There was significant improvement in disability and pain scores at two years. (p< 0.05). A significant difference in median DRAM between the preoperative and postoperative score at two years was noted.
Conclusion: The DRAM score highlights individuals in distress who may need psychological support and physical treatment for optimum benefit from endoscopic spinal intervention. While the DRAM score predicted the patients’ disability and pain it failed to predict percentage benefit gain in outcome.
