In univariate analyses, the probability of outpatient visits with no commercial insurance was higher than that with any other insurance (P < 0.05), and the probability of outpatient visits was higher in patients requiring 31–60 min transportation than that of within 30 min to reach a health facility (P < 0.05). Evaluation from a logistic regression analysis shows that time needed to access healthcare facilities and perceived convenience are not statistically significantly related to outpatient visits. Whereas, the number of chronic diseases are significantly related outpatient visits. It indicates that the more the number of chronic diseases relates to the more usage of outpatient visits, and number of chronic diseases is the most important factor.
