Impact of ultrasound scanning on pregnant Women's compliance with attendance at antenatal care visits and supervised delivery at primary healthcare centres in northern Nigeria: Initial experiences

Abstract

IntroductionThe world health organisation (WHO) recommends at least one ultrasound scan amidst eight antenatal care visits, however, most pregnant women in low and middle-income countries do not achieve this. This study aims to assess the impact of limited obstetrics ultrasound (LOUS) within primary healthcare centres in northern Nigeria. MethodsA cross sectional study was conducted across selected primary healthcare centres in Bauchi and Kano States (northern Nigeria). The study protocol was approved by the Ministry of Health in each State. Within each State a total of nine primary healthcare centres were randomly selected. Information on all complete antenatal care (ANC) records of women who used the primary healthcare facility for 12 months prior to introduction of ultrasound (January 2016 to December 2016) and 12 months after (January 2018 to December 2018) were collected. Study data were analysed using descriptive (mean, standard deviations) and inferential statistics. Independent sample t-test were used to find out if there was a statistical difference between the pre and post-intervention data on women compliance to ANC visits, facility based delivery, maternal and child mortality. Data were analysed using the Statistical Package for Social Sciences and significance was set at p ≤ 0.05. ResultsThere was a significant increase in the number of ANC visits and supervised facility delivery after introduction of ultrasound services (LOUS) in the primary healthcare centres. The number of ANC visits in Kano State was 2637.6 ± 972.0 before and 3793.0 ± 517.5 after the introduction of ultrasound services. The number of ANC visits in Bauchi State was 1866.6 ± 488.3 before and 2854.0 ± 631.3 after the introduction of ultrasound services. The number of supervised facility deliveries in Kano state was 520.1 ± 128.7 before and 1021.1 ± 217.0 after the introduction of LOUS. The number of supervised facility deliveries for Bauchi state was 553.1 ± 309.9 before and 1056.3 ± 295.4 after introduction of LOUS. A total of 2486 (11.0%) women were referred for further imaging due to equivocal ultrasound findings. A total of 2185 (9.7%) pregnant women were referred for appropriate care due to multiple gestations. ConclusionThis study found that LOUS, in resource scarce settings, has the potential of improving ANC visits, facility delivery rates and reduce maternal and child mortality. It also leads to change in patient management plans resulting in referrals for appropriate care. Implication for practiceTechnological interventions using ultrasound have the potential to motivate pregnant women to attend ANC, give birth in a healthcare facility and thus reduce maternal and child morbidity and mortality. This is in line with the global drive to reduce maternal and child death by 2030 to less than 70 maternal deaths in 100,000 live births and neonatal mortality reduction to 12 in 1000 live births and under 5 mortality reduction to 25 in 1000 live births.
