Nurse practitioners as attending providers for workers with uncomplicated back injuries: using administrative data to evaluate quality and process of care.
OBJECTIVE
The objectives of this study were 1) to identify quality and process of care indicators available in administrative workers' compensation data and to document their association with work disability outcomes, and 2) to use these indicators to assess whether nurse practitioners (NPs), recently authorized to serve as attending providers for injured workers in Washington State, performed differently than did primary care physicians (PCPs).


METHODS
Quality and process of care indicators for NP and PCP back injury claims from Washington State were compared using direct standardization and logistic regression.


RESULTS
This study found little evidence of differences between NP and PCP claims in case mix or quality of care.


CONCLUSIONS
The process of care indicators that we identified were highly associated with the duration of work disability and have potential for further development to assess and promote quality improvement.
