National Health Insurance and the antenatal care use: a case in Taiwan.

Many studies have found evidence for the importance of antenatal care on pregnancy outcomes. This paper focuses on the determinants of antenatal care use in Taiwan and provides a comparison of access to care before and after National Health Insurance (NHI) was implemented in 1995. A negative binomial model is applied to data from the 1989 and 1996 Taiwan Maternal and Infant Health Surveys to analyze antenatal care use. The results show that women in some situations had more antenatal care visits than average regardless of NHI implementation. These situations include: having a highly educated husband; gaining more weight than average during pregnancy; experiencing a first pregnancy; carrying twins or triplets; having care provided by a doctor rather than other caregivers; and switching to another health care facility during pregnancy. Regarding societal change, the trend toward delaying pregnancy is causing a change in care use. Additionally, three changes in care patterns after NHI are noteworthy. First, antenatal care visits at maternity clinics increased more than visits at hospitals. Second, before NHI's implementation, women who did blue-collar work or farm work sought care more frequently than housewives, but after NHI began government employees and businesswomen sought care more frequently. Third, antenatal care visits of mothers living in Taiwan's central area increased more than visits of those in the northern area. The expansion of medical care in aboriginal areas and outlying islands may prove to be one of NHI's best achievements.
