Changes in the care of patients with cervical spine fractures following health reform in Massachusetts

Abstract

Introduction: There is a substantial concern among spine surgeons that healthcare reform efforts will alter the processes through which spinal care is delivered and decrease overall quality. We used the Statewide Inpatient Dataset for Massachusetts to evaluate changes in hospital processes and quality of care for patients with cervical fractures following the implementation of health reform.

Methods: This was a pre-post retrospective analysis of patients (n=9,387) treated for cervical fractures in Massachusetts between 2003-2006 and 2008-2010. Changes in hospital processes (surgical intervention, length of stay (LOS) and environment of care) and quality of care (mortality, complications, reoperation and failure to rescue (FTR)) were the outcomes of interest. FTR is a quality measure that evaluates a hospital's capacity to avoid mortality following the occurrence of a sentinel complication. Patients treated between 2003 and 2006 were considered the pre-reform group. The post-reform cohort consisted of those treated from 2008 to 2010. Baseline differences between cohorts were evaluated using chi-square or Mann-Whitney U tests. Unadjusted comparisons between the dependent variables and the onset of healthcare reform were performed, followed by regression techniques that adjusted for differences in case-mix and whether a surgical intervention was performed. Multivariable logistic regression was used for categorical variables and negative binomial regression was employed for continuous variables.

Results: The rates of surgical intervention remained unchanged pre- and post-reform (p=0.25). Hospital length of stay (RC: -0.18, 95% CI: -0.22, -0.14) and the FTR rate following surveillance insensitive complications (OR: 0.49, 95% CI: 0.25, 0.94) were significantly reduced following health reform. Post-reform, academic centers experienced a 22% reduction in mortality (95% CI: 0.61, 0.99) a 40% decrease in FTR (95% CI: 0.40, 0.89), a 30% decrease in surveillance insensitive complications (95% CI: 0.51, 0.96) and a 67% reduction in FTR after surveillance insensitive morbidity (95% CI: 0.11, 0.94).

Conclusions: In the period following Massachusetts healthcare reform, significant improvements were noted in hospital process and quality measures around the care of patients with cervical spine fractures. Such findings were particularly robust among academic centers. These results may forecast changes in the delivery of spine surgical care following other health reform initiatives.
