Depression, anxiety, catastrophising, and fear-avoidance beliefs are some of the so-called “yellow flags” that predict a poor outcome in back patients. Many surgeons have difficulty assessing yellow flags, perhaps due to the complexity of existing instruments and time constraints during consultations. We developed a brief tool to allow the systematic evaluation of core flags. Data from 4 questionnaires (ZUNG depression (N=399); Hospital Anxiety and Depression Scale (Anxiety-subscale) (N=308); Pain Catastrophising (N=766); Fear Avoidance Beliefs (N=736)) were analysed to identify the respective single item that best represented the full scale score. The 4 items formed the “Core Yellow Flags Index” (CYFI). 1'768 patients completed CYFI and a Core Outcome Measures Index (COMI) preoperatively, and COMI 3 and 12mo later (FU).Background

Patient-rated measures are the gold standard for assessing spine surgery outcomes, but there is no consensus on the appropriate timing of follow-up. Journals often demand a minimum 2-year follow-up, but the indiscriminate application of this principle may not be warranted. We examined the course of change in patient outcomes up to 5 years postoperatively. The data from 3′334 consecutive patients (1′789 women, 1′545 men; aged 61±15 years) undergoing first-time surgery between 1.1.2005 and 31.12.2010 for differing lumbar degenerative disorders were evaluated. The Core Outcome Measures Index (COMI) was completed by 3′124 (94%) patients preoperatively, 3′164 (95%) at 3 months follow-up, 3′153 (95%) at 1 year, 3′112 (93%) at 2 years, and 2′897 (87%) at 5 years. 2′502 (75%) completed COMI at all five timepoints.Background
Methods
A new approach to the reporting of health outcomes involves assessing the proportion of patients achieving a level of symptoms that they feel they could live with. We evaluated the acceptable level of pain in patients after surgery for lumbar disc herniation (LDH). 12 mo after first-time surgery for LDH, patients completed 0–10 scales for back pain and leg pain and a question: “if you had to spend the rest of your life with the symptoms you have now, how would feel about it?,” answered on a 5-point Likert scale from “very satisfied” to “very dissatisfied”. This was dichotomised and used as the external criterion in receiver operating characteristics (ROC) analysis to derive the cut-off score for pain that best indicated being at least “somewhat satisfied” with the symptom state.Purpose
Methods
We carried out a retrospective review of 155 patients with lumbar spinal stenosis who had been treated surgically and followed up regularly: 77 were evaluated at a mean of 6.5 years (5 to 8) after surgery by two independent observers. The outcome was assessed using the scoring system of Roland and Morris, and the rating system of Prolo, Oklund and Butcher. Instability was determined according to the criteria described by White and Panjabi. A significant decrease in low back pain and disability was seen. An excellent or good outcome was noted in 79% of patients; 9% showed secondary radiological instability. Surgical decompression is a safe and efficient procedure. In the absence of preoperative radiological evidence of instability, fusion is not required.
We have developed criteria to determine the appropriate indications for lumbar laminectomy, using the standard procedure developed at the RAND corporation and the University of California at Los Angeles (RAND-UCLA). A panel of five surgeons and four physicians individually assessed 1000 hypothetical cases of sciatica, back pain only, symptoms of spinal stenosis, spondylolisthesis, miscellaneous indications or the need for repeat laminectomy. For the first round each member of the panel used a scale ranging from 1 (extremely inappropriate) to 9 (extremely appropriate). After discussion and condensation of the results into three categories laminectomy was considered appropriate in 11% of the 1000 theoretical scenarios, equivocal in 26% and inappropriate in 63%. There was some variation between the six categories of malalignment, but full agreement in 64% of the hypothetical cases. We applied these criteria retrospectively to the records of 196 patients who had had surgical treatment for herniated discs in one Swiss University hospital. We found that 48% of the operations were for appropriate indications, 29% for equivocal reasons and that 23% were inappropriate. The RAND-UCLA method is a feasible, useful and coherent approach to the study of the indications for laminectomy and related procedures, providing a number of important insights. Our conclusions now require validation by carefully designed prospective clinical trials, such as those which are used for new medical techniques.
