“…The discrepancy in the significant decline in the EQ-5D index from 1- to 2-year follow-ups while the SRS-22r subscores remained relatively similar might relate to reported poor concurrent validity between the two instruments found in the adolescent idiopathic scoliosis population [28]. …”

BackgroundProspective data on health-related quality of life in patients with idiopathic scoliosis treated surgically as adults is needed. We compared preoperative and 1- and 2-year follow-up data in surgically treated adults with idiopathic scoliosis with juvenile or adolescent onset. Results were compared to untreated adults with scoliosis and population normative data.MethodsA comparison of preoperative and 1- and 2-year follow-up data of 75 adults surgically treated for idiopathic scoliosis at a mean age of 28 years (range 18 to 69) from a prospective national register study, as well as a comparison with age- and sex-matched data from 75 untreated adults with less severe scoliosis and 75 adults without scoliosis, was made. Outcome measures were EuroQol-5 dimensions (EQ-5D) and Scoliosis Research Society (SRS)-22r questionnaire.ResultsIn the surgically treated, EQ-5D and SRS-22r scores had statistically significant improvements at both 1- and 2-year follow-ups (all p < 0.015). The effect size of surgery on EQ-5D at 1-year follow-up was large (r = −0.54) and small-medium (r = −0.20) at 2-year follow-up. The effect size of surgery on SRS-22r outcomes was medium-large at 1- and 2-year follow-ups (r = −0.43 and r = −0.42 respectively). At the 2-year follow-up, the EQ-5D score and the SRS-22r subscore were similar to the untreated scoliosis group (p = 0.56 and p = 0.91 respectively), but lower than those in the adults without scoliosis (p < 0.001 for both comparisons).ConclusionsAdults with idiopathic scoliosis experience an increase in health-related quality of life following surgery at 2-year follow-up, approaching the health-related quality of life of untreated individuals with less severe scoliosis, but remain lower than normative population data.

“…The EQ-5D can be used to compare spinal deformity surgery with that for other diseases and to achieve a utility index in the evaluation of cost effectiveness, while SRS-22r generates more specific information that can be used to evaluate the patient’s back-related health over time (Adobor et al 2010). …”

Background and purposeThere have been few prospective reports on quality of life in patients treated surgically for scoliosis. We compared patients with idiopathic, congenital, and neuromuscular scoliosis.MethodsData on 9- to 20-year-old patients were collected from the SweSpine registry. EQ-5D and (for a subset) SRS-22r were assessed preoperatively and after 1 and 2 years.Results211 patients had preoperative data: 168 with idiopathic, 11 with congenital, and 32 with neuromuscular scoliosis. Of the total, 158 patients responded to the 1-year follow-up and 149 responded to the 2-year follow-up. Preoperatively, the mean (SE) EQ-5D index was 0.76 (0.02) in the idiopathic group, 0.74 (0.07) in the congenital group, and 0.10 (0.06) in the neuromuscular group, and the SRS-22r index was 3.8 (0.1) in the idiopathic group, 4.0 (0.3) in the congenital group, and 3.3 (0.2) in the neuromuscular group. The mean EQ-5D increased by 0.06 points at 2 years in the idiopathic group, by 0.16 points in the congenital group, and by 0.15 points in the neuromuscular group. The mean SRS-22r index increased by 0.4 points at 2 years in the idiopathic group, by 0.4 points in the congenital group, and by 0.5 points in the neuromuscular group. The changes were statistically significant, with the exception of the congenital group. The number of patients who sustained at least 1 complication was 13 in the idiopathic group, 2 in the congenital group, and 9 in the neuromuscular group (p = 0.003).InterpretationThe general quality of life in the idiopathic and neuromuscular group improved after surgery.

BackgroundIt is recommended that research in patients with idiopathic scoliosis should focus on short- and long-term patient-centred outcome. The aim of the present study was to evaluate outcome in patients with late-onset juvenile or adolescent idiopathic scoliosis 16 years or more after Boston brace treatment.Methods272 (78%) of 360 patients, 251 (92%) women, responded to follow-up examination at a mean of 24.7 (range 16 - 32) years after Boston brace treatment. Fifty-eight (21%) patients had late-onset juvenile and 214 had adolescent idiopathic scoliosis. All patients had clinical and radiological examination and answered a standardised questionnaire including work status, demographics, General Function Score (GFS) (100 - worst possible) and Oswestry Disability Index (ODI) (100 - worst possible), EuroQol (EQ-5D) (1 - best possible), EQ-VAS (100 - best possible), and Scoliosis Research Society - 22 (SRS - 22) (5 - best possible).ResultsThe mean age at follow-up was 40.4 (31-48) years. The prebrace major curve was in average 33.2 (20 - 57)°. At weaning and at the last follow-up the corresponding values were 28.3 (1 - 58)° and 32.5 (7 - 80)°, respectively. Curve development was similar in patients with late-onset juvenile and adolescent start. The prebrace curve increased > 5° in 31% and decreased > 5° in 26%. Twenty-five patients had surgery. Those who did not attend follow-up (n = 88) had a lower mean curve at weaning: 25.4 (6-53)°. Work status was 76% full-time and 10% part-time. Eighty-seven percent had delivered a baby, 50% had pain in pregnancy. The mean (SD) GFS was 7.4 (10.8), ODI 9.3 (11.0), EQ-5D 0.82 (0.2), EQ-VAS 77.6 (17.8), SRS-22: pain 4.1 (0.8), mental health 4.1 (0.6), self-image 3.7 (0.7), function 4.0 (0.6), satisfaction with treatment 3.7 (1.0). Surgical patients had significantly reduced scores for SRS-physical function and self-image, and patients with curves ≥ 45° had reduced self-image.ConclusionLong-term results were satisfactory in most braced patients and similar in late-onset juvenile and idiopathic adolescent scoliosis.

Repeatability, Reliability, and Concurrent Validity of the Scoliosis Research Society-22 Questionnaire and EuroQol in Patients With Adolescent Idiopathic Scoliosis

Abstract: The SRS-22 outcome instrument has satisfactory repeatability, but CD with EQ-5D suggests that the disease-specific and the generic questionnaire measure different constructs.
