Table 6 Output of stepwise OLS regression, modeling the effects of practice, EHR* usage, purpose of prior authorization request, insurance type involved, reporter type, and rurality of the practice location

From: Practice characteristics and prior authorization costs: secondary analysis of data collected by SALT-Net in 9 central New York primary care practices

Variable Beta t p Lower bound (95% CI) Upper bound (95% CI)
Constant 20.017 13.018 <.001 16.995 23.040
Practice X 11.389 6.108 <.001 7.724 15.054
Purpose - OT/PT† −8.716 −4.847 <.001 −12.250 −5.182
Medicaid −6.085 −3.871 <.001 −9.174 −2.995
EHR in use −5.086 −3.085 .002 −8.327 −1.845
  1. Model Parameters: R2 = .154; F = 19.506, p < .001.
  2. Dependent Variable: Time (in minutes) of each Prior Authorization event.
  3. Independent Variables removed from equation: All practice indicator variables aside from one (Practice X); all purposes for PA calls aside from OT/PT; all other insurance types aside from Medicaid; rurality; all reporter types (physician, nurse, clerical, etc.).
