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.
In contrast to past studies that health insurance increases healthcare utilization [14], the patients with commercial insurance used less hospitalization services. However, this study was conducted in a country that all citizens are covered by NHI. The patients with extra self-paid commercial insurance might indicates better level of economic situation, and might use less medical services. Logistic regression analysis shows that age, number of chronic diseases and time needed to medical care are main factors affecting hospitalization.
Univariate analysis shows that there is a significant relationship between chronic diseases situations and perceived convenience to emergency visits (P < 0.05). Logistic regression analysis also shows that age, number of chronic diseases and perceived convenience are the main factors for emergency use. Elderly patients above 75 years of age, with more number of chronic diseases and perceive inconvenient had
