Purpose
To determine if preoperative Health Related Quality of Life (HRQoL) has declined in the past two decades for patients with Adolescent Idiopathic Scoliosis (AIS), as measured by the Scoliosis Research Society (SRS) questionnaire.
Methods
A retrospective review was conducted on AIS patients that underwent surgery at a single institution between 2002 and 2022. Patients were included if they completed an SRS questionnaire preoperatively. A multivariate linear regression was performed with the SRS domains as the dependent variables. The independent variables were surgery year, gender, race/ethnicity, BMI, Lenke type, and major Cobb angle. A second regression was performed where the SRS scores for AIS patients were dichotomized as being above or below normal based on a threshold set at two standard deviations below the mean SRS scores of a healthy adolescent population. The binary SRS scores were used as the outcome of interest in a second regression.
Results
A total of 1380 patients (79.2% female, mean age 14.9 ± 2.0 years old) were included for analysis. Surgery year had a negative association with Pain (coefficient = − 0.03,
p
< 0.0001), Activity (coefficient = − 0.02,
p
< 0.0001), Mental Health (coefficient = − 0.01,
p
< 0.0001), and Total score (coefficient = − 0.01,
p
< 0.0001), indicating declining HRQoL over time. Similarly, AIS patients became more likely to fall below 2SD of the healthy adolescent means in Pain (OR: 1.061, p < 0.0001), Appearance (OR: 1.023,
p
= 0.0301), Activity (OR: 1.044,
p
= 0.0197), and Total score (OR: 1.06,
p
< 0.0001).
Conclusion
Over the past two decades, patients with surgical AIS have experienced a significant decline in various HRQoL domains preoperatively.
