[Quality analysis and evaluation of surgery for herniated lumbar disk. I. Methodology]

Area of Science:

• Spine surgery outcomes assessment
• Health services research methodology
• Quality improvement in healthcare

Context:

• Evaluating the quality of lumbar disc surgery is crucial for patient outcomes and healthcare efficiency.
• Existing methods may not comprehensively capture all relevant quality dimensions.
• A standardized, multi-parameter approach is needed for robust surgical quality analysis.

Purpose:

• To develop and present a novel method for analyzing the quality of lumbar disc surgery.
• To integrate multiple quality parameters including scientific and technical quality (STQ), functional outcomes, quality of life, patient satisfaction, and economic costs.
• To establish a systematic procedure for performance evaluation in clinical documentation.

Summary:

• The developed method assesses lumbar disc surgery quality using the Performance Evaluation Procedure (PEP) method for scientific and technical quality (STQ).
• Functional outcomes are measured using modified Spanfort's criteria, and quality of life is assessed via a modified 12-item Short Form health survey.
• Patient satisfaction is gauged through a specifically designed questionnaire, incorporating patient and professional feedback, while costs are analyzed using three distinct economic systems.

Impact:

• Provides a holistic framework for evaluating surgical quality, moving beyond single-metric assessments.
• Facilitates data-driven improvements in lumbar disc surgery protocols and patient care.
• Enables healthcare providers and policymakers to benchmark performance and optimize resource allocation for spinal procedures.
