Abstract
Recent years have witnessed a paradigm shift in relation to the assessment of outcome in spine surgery: multidimensional patient-centred questionnaires have superseded traditional surgeon-based ratings of outcome, and surgical registries have been developed to capitalise on the principle of "strength in numbers." However, the assessment of complications has not enjoyed this same enlightened patient-centred approach. The present study investigated post-surgical complications from the patient's perspective. All German-speaking patients undergoing surgery within our Spine Center in 2005 were asked to complete the patient-orientated Core Measures Outcome Index of the SSE Spine Tango Spine Surgery Registry before and 12 months after surgery; the surgeon completed a Spine Tango surgery form. In the 12-month questionnaire, the patient was asked, "did any complications arise as a consequence of your operation 1 year ago (e.g. problems with wound healing, paralysis, sensory disturbances, etc.)? If so, give details." Patients were also asked about their satisfaction with the operation and the global outcome of surgery. 1,035 patients were sent a 12-month questionnaire; 972 (94%) returned the completed questionnaire. 29% patients answered "yes" to the question about complications. The incidence of patient-rated complications was significantly associated with outcome/satisfaction (P < 0.05), suggesting these complications were not trivial to the patient. The results indicate that, just like outcome, "complications" should be assessed from both the patient's and the surgeon's perspectives, not least to better understand the reasons accounting for dissatisfaction and a poor patient-rated outcome.
