Factors associated with preoperative health-related quality of life in patients undergoing lumbar spine surgery: a multi-ethnic Asian cohort.
To examine sociodemographic, clinical, and healthcare-related factors associated with preoperative health-related quality of life (HRQoL) among patients undergoing surgery for degenerative lumbar spine conditions in a multi-ethnic Asian population.
This cross-sectional study used baseline data from the Spine PROM Surgery Registry, including 1194 patients scheduled for surgery within a Singapore healthcare cluster between 2017 and 2022. HRQoL was measured using the EQ-5D-3L, with utility scores crosswalked to the EQ-5D-5L index using the van Hout crosswalk. Hierarchical linear regression assessed factors associated with HRQoL across three blocks: sociodemographic, clinical, and healthcare/lifestyle. Multivariable logistic regression identified factors associated with reporting problems within each EQ-5D dimension.
Mean age was 58.1 years (SD 16.1); 51.5% were female. Mean EQ-5D-5L index was 0.43 (SD 0.38). Pain/discomfort (93.6%) and usual activities problems (84.3%) were most commonly reported. Lower EQ-5D scores were independently associated with non-outpatient presentation (β = -0.37), non-Chinese ethnicity (e.g., Malay: β = -0.10), secondary education (β = -0.15), and accident/trauma history (β = -0.11). Dimension-level analyses showed secondary education was associated with higher odds of problems in mobility (OR = 2.72), self-care (OR = 1.87), usual activities (OR = 1.80), and anxiety/depression (OR = 1.97). Non-outpatient presentation was associated with markedly higher odds of self-care problems (OR = 2.98).
Patients awaiting lumbar spine surgery appear to have impaired preoperative HRQoL. Although the modest explained variance limits robust risk prediction, preoperative profiles may still help inform clinical discussions and shared decision-making. Non-outpatient presentation may help identify patients who could benefit from enhanced preoperative support, although this requires prospective validation. Differences by ethnicity and education suggest opportunities for culturally tailored counselling. EQ-5D dimension profiles may indicate targets for prehabilitation and provide Singapore-based benchmark data for a lumbar spine surgery cohort for patient-centred care, service benchmarking, and health technology assessment.
