Neonatal Statistics of Korea in 1996: Collective Results of Live - Births , Neonatal Mortality , and Incidence of Dischage Against Medical Advice at 64 Hospitals

ABSTRACT

PURPOSE: To evaluate the nation-wide results of statistics related to the neonatal period of 1996, we collected data of a total of 64 hospitals in Korea (42 university hos- pitals and 22 general hospitals). METHODS: We obtained the results of 129,175 inboms and 9,379 outborns, and analyzed the statistics of live-births, ig, distribution of live-births by gestational age and birth weight, incidence of pre-term infants and low birth weight infants (LBWI), neonatal mortality, and incidence of discharge against medical advice (DAMA). RESULTS: According to birth weight, incidence of LBWI, normal birth weight, infant and high birth weight infants was 3.6%, 86.6% and 9.8%, respectively in the case of inborn group. But incidence of LBWI was higher in outborn group as compared with the inbom group. According to gestational age, incidence of preterm, term, and post-term was 11.1%, 87.1Yo and 1.8% respectively in the inbom group. The incidence of preterm in outborn group was higher than that of inborn group, because of the influnce of transpor- tation of high risk neonates to 2nd or 3rd levels of neonatal intensive care units (NICU). Overall neonatal mortality per 1,000 live-births was 9.3 in the inborn group amd 37.6% in the outborn group. These data revealed a high neonatal mortality, because the numbers of DAMA cases was also included. The incidence of DAMA was 0.44% and 1.15% in inborn and outborn groups, respectively. The percentage of the DAMA among the numbers of neonatal mortality was 47.2-48.8M in the inborn group. CONCLUSIONS: We obtained the statistics related to live-birth, incidence of prematurity and LBWI, neonatal mortality, and incidence of DAMA in Korea. The data revealed high levels of neonatal mortality (which included the sum of neonatal death and the number of DAMA) and incidence of DAMA in Korea at present. To achieve a low-level of neonatal mortality, more efforts to decrease the incidence of DAMA are needed. Also, a greater facility for NICU and a stronger support system from a nation-wide govemment policy and system of insurance are seen to be necessary.
