Abstract
Background
Recent years have witnessed a paradigm shift in the assessment of outcome in spine surgery, with patient-centred questionnaires replacing traditional surgeon-based assessments. The assessment of “complications” — loosely defined as new/unexpected problems arising as a result of surgery — has not enjoyed this same enlightened approach.
Methods
Patients with lumbar degenerative disorders operated with the goal of pain relief, completed a questionnaire 1 year post-operatively enquiring about complications arising as a consequence of their operation. They rated the bothersomeness of any such complications on a 5-point adjectival scale. Global outcome of surgery and satisfaction were rated on 5-point Likert scales.
Results
Of 2946 (92% compliance) patients completing the questionnaire, 861 (29%) reported complications, most commonly sensory disturbances (37% of those with complications) or ongoing pain (22%), followed by motor problems (9%), pain plus sensory disturbances (8%), and problems with wound healing (6%). The corresponding “bothersomeness” ratings for these were: 1% not at all, 23% slightly, 26% moderately, 31% very, and 19% extremely bothersome. Bothersomeness was significantly correlated with global outcome (Rho=0.51, p<0.0001) and satisfaction (Rho=0.43, p<0.0001). A good global outcome was reported by 80% of patients with no complications and only 58% of those with complications; satisfaction was 88% and 72%, respectively.
Conclusion
Most complications reported by the patient are perceived to be at least moderately bothersome and are hence not inconsequential. Complications and their severity should be assessed from both the patient's and the surgeon's perspective — not least to better understand the reasons for poor outcome and dissatisfaction with treatment.
