Results of the perinatal audit of the Northwestern Federal District

Abstract

Aim. To assess the results of a perinatal audit of the Northwestern Federal District and to identify opportunities for a decrease in perinatal mortality.

Methods. The audit of perinatal loss was conducted in two stages: (1) remote audit — audit of perinatal mortality indicators; (2) medical history audit — audit of cases of perinatal death of a child based on medical documentation. Held the copy of the data from the 925 medical records for 220 cases of perinatal death. The perinatal audit of the Northwestern Federal District used the Nordic-Baltic perinatal death classification. The following statistical me­thods were used for statistical data processing: incidence rate of a trait was determined by using frequency tables, the statistical significance of differences was tested by using contingency tables, the Chi-square criterion, along with the Pearson correlation coefficient. The statistical significance of differences in quantitative indicators was assessed by using Student's t-Test. The significance level was set at p <0.05.

Results. It was found that in the Northwestern Federal District pregnancy losses III category of the Nordic-Baltic classification (gestational age newborn, more than 28 weeks, without congenital malformations and intraute­rine growth restriction) is 27.5%, intranatal losses VI category of the Nordic-Baltic classification (gestational age newborn, more than 28 weeks, without congenital malformations and intrauterine growth restriction) — 7.4%, the loss of newborns VIII–XI category of the Nordic-Baltic classification (gestational age newborn, more than 28 weeks, without congenital malformations and intrauterine growth restriction) — 16.9%. Among children who died during the perinatal period, children of gestational age over 28 weeks significantly predominate (p=0.003). In the nosological structure of stillbirth, most of the diseases are associated with respiratory disorders (85.9%), infectious complications are 14.1%. The main causes of death of newborns in the early neonatal period are respiratory disorders — 40.0% and infectious diseases specific to the perinatal period — 36.0%. The assessment of the sexual prevalence of pregnancy losses did not reveal a statistically significant difference (p=0.29). The assessment of the sexual characteristics of intranatal losses showed that boys significantly predominate (p=0.003).

Conclusion. The perinatal audit revealed that, in the Northwestern Federal District, the level of the mobile reserve of perinatal losses associated with managed causes is 51.8%.
