Incidence of maternal infection and its related outcomes in a public sector hospital in Pakistan.

Background: Maternal infections are responsible for maternal mortality and can lead to adverse pregnancy outcomes such as stillbirth, maternal sepsis, and spontaneous abortion as well as dire outcomes for the neonate. The impact of obstetric infections is largely felt in low- and middle-income countries, with Pakistan being one such country.

Objectives: To assess the frequency of maternal infections, the common sources responsible for their progression and their resulting impact on pregnancy, maternal, and neonatal health outcomes.

Design: An observational cross-sectional study was conducted in a tertiary care, public sector hospital in Pakistan.

Methods: A total of 439 women, either antenatal or postnatal, with symptoms of infection were enrolled. Case report forms were used to collect data on clinical characteristics, type of infection, investigational and diagnostic profile, and pregnancy, maternal, and neonatal outcomes. Frequency and percentages were computed for categorical variables. Comparisons of pregnancy and neonatal outcomes were analyzed by the chi-square test or Fisher's exact through categorization of patients as per the severity of their condition.

Results: The observed frequency of maternal infections was 12% in pregnant or recently pregnant women admitted during the study period. Respiratory tract infection (16.9%) and chorioamnionitis (14.4%) were more prevalent among antenatal women, whereas wound/skin infection (15.5%) and puerperal/genital tract infection (12.3%) were the most common infections observed in postnatal women. Blood transfusion was the most common complication observed in the included women (26.9%). Among the study population, 13.9% had organ dysfunction, primarily cardiovascular (42.6%) and neurological dysfunction (40.9%). Women with severe infection had adverse pregnancy outcomes such as a high number of still births (17.5%). The total number of maternal deaths recorded was 19 (4.32%). Regarding neonatal outcomes, APGAR score, suspicion of infection, and low birth weight were significant across the severity groups. There was no significant difference for neonatal deaths across the three groups.

Conclusion: Infections from various sources contribute significantly toward adverse maternal, pregnancy, and neonatal outcomes. Enforcing infection prevention measures, equipping primary healthcare units with adequate resources and emphasizing antenatal and postnatal care can prevent infections and their related complications. Early detection and management of maternal infections is equally necessary.
