Orthopedic office medical records using COSTAR.

Computer stored ambulatory record (COSTAR) is a public domain medical data management system designed to replace traditional, paper-based office medical and financial records. COSTAR is an integrated, modular system that can be implemented incrementally for medical records, accounts receivable, scheduling, and report generation. Combined with medical query language (MQL), COSTAR provides a valuable tool to implement protocols for clinical practice, research, quality assurance, and economic cost performance without redundant data entry.
