Evaluating the influence of patient traits versus surgical intervention on outcomes across spine surgeries: a latent state-trait analysis.

Key Points

• To analyze how patient traits and surgical interventions influence outcomes in spine surgeries.
• Latent state-trait analysis of the PROMIS-10 instrument was performed.
• Comparative analysis of outcomes across different types of spine surgeries.
• Focus on patient characteristics influencing reported outcomes.
• Outcomes influenced by surgical experiences for patients with high state dependence.
• Patients with high trait dependence showed outcomes driven primarily by innate characteristics.
