Utilization of health services as events: an exploratory study.
The concept of propensity to use ambulatory care is defined as the probability that a utilization occurs in a very small interval of time, given that no utilization has been observed before. With this definition of utilization, survival analysis can be used to assess the effect of a set of predictors on utilization. The results of this analysis are compared with the results of the prediction of utilization by the same set using a logistic regression model and a linear regression model.
