[Stillbirth rate and perinatal mortality--criteria for quality of prenatal obstetric care].

AIM
To determine the frequency and structure of stillbirth rate, its relative share compared to PM, the trends for the period of 2007-2012 and their dependence to birth weight of the fetus and newborn.


MATERIAL AND METHODS
The birth rate, stillbirth rate and PM for the period of 2007-2012 have been followed up retrospectively according to data provided by the department of Obstetrics & Gynecology in University hospital "St. George" Plovdiv. The trends of those two indicators have been established, their relationship to and dependence of fetal and newborn birth weight. Representative and correlative analyses have been used.


RESULTS
During the period being analyzed 13 558 deliveries have been registered. 13.4 per thousand (183) of them are stillbirths, and 92.3% (169) died antenatal. After 2010 the birth rate decreases. Stillbirth rate increases from 13 per thousand in 2009 to 20.6 per thousand in 2012. It is mostly due to prematurity, which for the past two years are mostly with extremely low birth weight (57.2%). Antenatal stillbirth rate prevails. Intranatal fetal death is being observed significantly less, but in those cases where it is, the premature with weight 600-999 grams play a major role. Increased stillbirth rate maintains a high PM and constitute more than 2/3 of it.


CONCLUSIONS
Against the backdrop of lower birth rate, the stillbirth rate and PM remain high. In the last 2 years they are presented mainly by premature weighing 600-999 grams. The prevalence of antenatal stillbirth rate means good control of delivery but refers to the prenatal period, which is related to the quality of the obstetric care.
