Backgrounds: According to Statistics of birth reporting system by Ministry of Health and Welfare, there is a downward trend in the annual number of live births from 2004 to 2014. The proportions of newborns born before 37 weeks has risen from 8.92% in 2004 to 8.95% in 2014, indicating a high proportion of preterm infants, and the birth rates of very low birth weight infants (VLBW) also increased with year. Among newborns of live births from the recent three-year birth reporting data, the rates of premature infants were 8.95% -9.05%, and the rates of VLBW infants were 0.82% -0.86%. The VLBW infants are subject to have high mortality and morbidity rates. Therefore, in addition to prevent preterm births, it is essential to improve newborn survival rate by reducing high mortality rate of VLBW infants. Objectives: The study aimed to identify factors influencing health outcomes of VLBW infants. We adopted information from Longitudinal Health Insurance Database 2010 of Taiwan (LHID2010) and examined the properties of neonatal factors, medical institutions and physicians’ characteristics that may influence health outcomes of VLBW infants. Methods: In this retrospective study, we adopted the information from Longitudinal Health Insurance Database 2010 of Taiwan (LHID2010) and merged the following Registration files: Inpatient Expenditures by Admissions (DD), Details of inpatient orders(DO), Registry for Contracted Medical Facilities (HOSB), Registry for Medical Personnel (PER), Registry for Board-certified Specialists (DOC), and Registry for beneficiaries (ID). The subjects of the study are VLBW infants (birth weight less than 1500 grams) and we tracked health care outcomes after its first hospitalization. We employed multiple regression analyses to detect significant factors. Results: In 350 VLBW infants of the study, 187 were males (53.43%) and 163 were females (46.57%). 344 (98.29%) survived after the study period. The means of the first time and the first year hospital costs were NT 353,444 (SD = 432,968) and NT 652,101 (SD = 498,960), respectively. With respect to characteristics of VLBW infants, that expenses of the first time hospitalization were lower when birth weight were heavier (P
