Background: Audit is an essential component of healthcare quality improvement. When conducted systematically with predefined standards, it allows institutions to evaluate performance and identify areas for refinement. This audit aimed to evaluate epidemiological characteristics, perioperative parameters, and early complications of spinal deformity surgery at our tertiary spine institute against predefined institutional benchmarks.

Methods: A retrospective audit was performed of patients who underwent deformity correction between 1 January 2019 and 31 December 2020. Institutional standards were predefined through departmental consensus based on contemporary spine literature and institutional performance data. Parameters assessed included operative time, blood loss, hospital stay, and early complications (within 90 days). Descriptive statistics were used.

Results: Seventy-two patients were included. The mean age was 34.92 ± 25.88 years (range 5–80; median 22.5), with 40 males and 32 females. Mean hospital stay was 7.67 ± 4.50 days (range 1–23). Mean blood loss was 911.67 ± 383.34 mL. Mean operative time was 379.03 ± 134.77 minutes. There were 52 scoliosis surgeries (72.2%), 10 kyphosis (13.9%), and 10 kyphoscoliosis (13.9%). Three patients (4.2%) developed early complications: two transient neurological deficits and one pseudomeningocele.

Conclusion: This audit establishes baseline institutional performance data. Perioperative parameters and complication rates were within predefined internal targets. The findings provide a framework for structured quality monitoring and future re-audit.
