Values are coefficient (SE). Results are from linear regression models of hospital risk-adjusted 30-day complication rates regressed on the percentage of positive responses on the SAQ scaled to 10% increments (range 1 to 10) and hospital characteristics from the American Hospital Association 2013 annual survey and the American Nurses Credentialing Center.
