Multicentric Retrospective Study of Perinatal Mortality

Study Overview
=================
Brief Summary
-----------------
Background: Perinatal mortality ranges mortality from 22 gestational weeks up to the first 7 days of life and extended mortality goes up to 28 days of life. The perinatal mortality rate is the most sensitive index of the health status of women and their offspring and of the quality of maternal and child health services. Per our knowledge, there is no study that evaluates perinatal mortality in Catalonia, although household data are available from each hospital. Moreover, the official records usually do not match with the household surveys due to lack of clarity on the definitions. Aim: the aim of the study is to compare the WHO perinatal mortality classification following the ICD-PM in comparison with the used classification. Methodology: Multicentric retrospective study. Data from Sant Joan de Déu, Maternitat Clinic and Parc Taulí hospitals.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| International Classification of Disease (10th Revision)- Perinatal Mortalitymaternal condition group | The ICD-PM provides a standardised system for classifying perinatal mortality (including stillbirths) based on time of death (antepartum or intrapartum) into fetal and maternal causes thereby enabling comparisons within and between diverse settings and contexts | through study completion, an average of 1 year | 
| International Classification of Disease (10th Revision)- Perinatal Mortality cause of death | The ICD-PM provides a standardised system for classifying perinatal mortality (including stillbirths) based on time of death (antepartum or intrapartum) into fetal and maternal causes thereby enabling comparisons within and between diverse settings and contexts | through study completion, an average of 1 year |
