Note. N = 57 providers with a total of 187 observations across time. Demographic variables including race, sex, age, time employed, and position type were deleted from the model to simplify results as they were nonsignificant and did not affect results. Variance components in the model included random intercepts for both the Poisson and inflated zero portions of the model (Poisson, .61, SE = ..29, p < .05; inflated zero, 1.46, SE = 1.08, p = .18).
