Original ContributionFocused Maternal Ultrasound by Midwives in Rural Zambia
Section snippets
Introduction and Literature
Over the last decade, ultrasound technology has become more compact, interface software has simplified and machine costs have decreased. As a result, the advantages of portable diagnostic imaging can be accessed in an increasing number of clinical settings. One particular area of interest has been the use of ultrasound in resource-scarce settings where access to imaging diagnostics is severely limited (Dean et al., 2007, Kobal et al., 2004, Shah et al., 2008, Spencer and Adler, 2008, Steinmetz
Sites
The study was carried out at three sites in the Kapiri Mposhi District within the Central Province of Zambia: Kapiri District Hospital, Mukonchi Rural Health Center, and Nkole Rural Health Center. In 2008, Kapiri District Hospital assisted 1927 deliveries; Mukonchi had 278 deliveries; and Nkole 126 deliveries. Neither the hospital nor the health centers have the capacity to perform cesarean sections. Patients must be referred to a regional hospital 60 km away in a neighboring district (Kabwe
Ultrasounds recorded
A total of 21 of midwives underwent focused obstetric ultrasound training. The mean number of scans per midwife was 21 (range 1–179). Four hundred and forty-one ultrasound scans were recorded over the 6-month study period (Table 1). Most recorded scans were performed in second and third trimester as this is the time most patients presented to antenatal clinic or to the labor ward. One hundred ninety-one (43%) of the scans were supervised by one of the training physicians, the rest were
Discussion and Summary
There is limited published literature regarding ultrasound as a tool for responding to the high rates of maternal and newborn morbidity and mortality in the developing world. The data from our pilot program indicate that midwives in rural Zambia with no prior ultrasound experience can be trained to use a portable ultrasound machine to perform basic obstetric ultrasound. Not only were they able to learn a new technology, they retained their skills over the 6-month study period and they began to
Conclusion
Midwives in rural Zambia can be taught basic obstetric ultrasound applications, such as identifying number of gestations, locating fetal heart rate and identifying fetal presentation. They are able to retain those skills over a 6-month time period and continued to utilize the ultrasound at a one-year impact assessment. Clinical decision-making was altered in 17% of patients scanned. More data is necessary to assess the long-term sustainability of the skills learned and to determine whether the

(2015). Effect estimates for change in management ranged from 17% in Kimberly et al. (2010) to 87% in Epstein et al. (2018). The quality of the evidence relating to change in diagnosis and change in management was assessed as moderate.

2022, RadiographyCitation Excerpt :It is quite unfortunate that the majority of women in LMICs, especially in sub-Saharan Africa, will go through pregnancy period without the privilege and benefit of a single ultrasound scan.34,42–44 Technological advances have made ultrasound machines now compact and portable, making it possible to provide ultrasound services in an increasing number of clinical settings such as in the primary healthcare centres in rural communities where access to imaging services are scarce.34,37,38,45,46 This study aims to determine the impact of limited obstetrics ultrasound (LOUS) services on women's compliance with ANC visits and facility deliveries in the primary healthcare centres in northern Nigeria.
