Scoliosis Society Morbidity, Mortality Database Validated

Complication rates for common spinal surgeries comparable to those in previous research

MONDAY, Dec. 6 (HealthDay News) -- The Scoliosis Research Society's morbidity and mortality database (SRS M and M) is valid for the study of spinal disorders based on its reported major complication rates for three common spine procedures, according to research published in the Nov. 15 issue of Spine.

Justin S. Smith, M.D., Ph.D., of the University of Virginia Medical Center in Charlottesville, and colleagues assessed complication rates for three common spinal surgeries collected for the SRS M and M and compared those results with previous studies. They also investigated the database for instances of pulmonary embolism (PE) and deep venous thrombosis (DVT) from 2004 to 2007.

The reviewers identified 9,692 lumbar microdiscectomies (LDs), 6,735 anterior cervical discectomy and fusions (ACDFs), and 10,329 lumbar stenosis decompressions (LSDs), with overall complication rates of 3.6, 2.4, and 7.0 percent, respectively. The rates were comparable to those of previously published smaller studies. In addition, of the 108,419 cases of PE and DVT identified, the overall rates of PE, DVT, and death due to PE were 1.38, 1.18, and 0.34 per 1,000 cases, respectively.

"Overall major complication rates for LD, ACDF, and LSD based on the SRS M and M database are comparable to those in previously reported smaller series, supporting the validity of this database for study of other less common spinal disorders. In addition, our data provide general benchmarks of clinically evident PE and DVT rates as a basis for ongoing efforts to improve care," the authors write.

One or more of the authors disclosed ties to a commercial party related directly or indirectly to the research.
