ABSTRACT
STUDY DESIGN:
Retrospective review of a prospective database.OBJECTIVE:
The aim of this study was to evaluate postop clinical recovery among adult spinal deformity (ASD) patients between frailty states undergoing primary procedures SUMMARY OF BACKGROUND DATA. Frailty severity may be an important determinant for impaired recovery after corrective surgery.METHODS:
It included ASD patients with health-related quality of life (HRQLs) at baseline (BL), 1 year (1Y), and 3 years (3Y). Patients stratified by frailty by ASD-frailty index scale 0-1(no frailty <0.3 [NF], mild 0.3-0.5 [MF], severe >0.5 [SF]). Demographics, alignment, and SRS-Schwab modifiers were assessed with χ/paired t tests to compare HRQLs Scoliosis Research Society 22-question Questionnaire (SRS-22), Numeric Rating Scale (NRS) Back/Leg Pain, Oswestry Disability Index (ODI). Area-under-the-curve (AUC) method generated normalized HRQL scores at baseline (BL) and f/u intervals (1Y, 3Y). AUC was calculated for each f/u, and total area was divided by cumulative f/u, generating one number describing recovery (Integrated Health State [IHS]).RESULTS:
A total of 191 patients were included (59 years, 80% females). Breakdown of patients by frailty status 43.6% NF, 40.8% MF, 15.6% SF. SF patients were older (P = 0.003), >body mass index (P = 0.002). MF and SF were significantly (Pâ<â0.001) more malaligned at BL pelvic tilt (NF 21.6°; MF 27.3°; SF 22.1°), pelvic incidence and lumbar lordosis (7.4°, 21.2°, 19.7°), sagittal vertical axis (31âmm, 87âmm, 82âmm). By SRS-Schwab, NF were mostly minor (40%), and MF and SF markedly deformed (64%, 57%). Frailty groups exhibited BL to 3Y improvement in SRS-22, ODI, NRS Back/Leg (Pâ<â0.001). After HRQL normalization, SF had improvement in SRS-22 at year 1 and year 3 (Pâ<â0.001), and NRS Back at 1Y. 3Y IHS showed a significant difference in SRS-22 (NF 1.2 vs. MF 1.32 vs. SF 1.69, Pâ<â0.001) and NRS Back Pain (NF 0.52, MF 0.66, SF 0.6, P = 0.025) between frailty groups. SF had more complications (79%). SF/marked deformity had larger invasiveness score (112) compared to MF/moderate deformity (86.2). Controlling for baseline deformity and invasiveness, SF showed more improvement in SRS-22 IHS (NF 1.21, MF 1.32, SF 1.66, Pâ<â0.001).CONCLUSION:
Although all frailty groups exhibited improved postop disability/pain scores, SF patients recovered better in SRS-22 and NRS Back. Despite SF patients having more complications and larger invasiveness scores, they had overall better patient-reported outcomes, signifying that with frailty severity, patients have more room for improvement postop compared to BL quality of life.
