Health professionals' experiences and views on obstetric ultrasound in Tanzania: A cross-sectional study

Background: Obstetric ultrasound is considered important for determining gestational age, identifying single or multiple pregnancies, locating the placenta and fetal anomalies and monitoring fetal growth and pregnancy-related complications in order to improve patient management.Objectives: To explore health professionals' perspectives on different aspects of obstetric ultrasound in Tanzania regarding self-reported skills in performing ultrasound examinations and what could improve access to and utilization of obstetric ultrasound in the clinical setting.Design: Cross-sectional study.Material and Methods: Data was collected between November and December 2017 using a questionnaire based on previous qualitative research results from the CROss Country UltraSound Study (CROCUS Study). Seventeen healthcare facilities in 5 urban and semiurban municipalities in the Dar-es-Salaam region were included, with 636 health professionals participating (physicians, n = 307 and midwives/nurses, n = 329).Results: Most health professionals (82% physicians, 81% midwives/nurses) believed that obstetric ultrasound was decisive in the clinical management of pregnancy. Results indicate proficiency gaps across disciplines: 51% of physicians and 48.8% of midwives/nurses reported no or low-level skills in assessing cervical length. Similarly, deficiencies were observed in evaluating the four-chamber view of the fetal heart (physicians: 51%, midwives/nurses: 61%), aorta, pulmonary artery (physicians: 60.5%, midwives/nurses: 65%) and Doppler assessments (umbilical artery: physicians 60.6%, midwives/nurses 56.1%). Compared to midwives/nurses, physicians were significantly more likely to agree or strongly agree that utilization would improve with more ultrasound machines (odds ratio (OR) 2.13; 95% confidence intervals (CI) 1.26-3.61), better quality of ultrasound machines (OR 2.27; 95% CI 1.10-4.69), more training for health professionals currently performing ultrasound (OR 2.11; 95% CI 1.08-4.17) and more physicians trained in ultrasound (OR 2.51; 95% CI 1.30-4.87).Conclusions: Improving the provision of obstetric ultrasound examinations in Tanzania requires more and better-quality ultrasound machines, enhanced training for health professionals and an increased number of physicians trained in ultrasound use. To further increase the accessibility and utilization of obstetric ultrasound in maternity care in Tanzania, it is essential to provide training for midwives in basic obstetric ultrasound techniques. A study reporting on health professionals' insights and skills regarding pregnancy scans in TanzaniaThis study, conducted in Tanzania, explores health professionals' perspectives on obstetric ultrasound, an important component believed to increase antenatal care attendance in low-income countries. The research was carried out through a cross-sectional study involving 636 health professionals, primarily physicians and midwives/nurses, to assess their self-reported skills in performing obstetric ultrasound examinations and identify factors that could enhance access to and utilization of obstetric ultrasound in clinical settings. The findings highlight that most health professionals view obstetric ultrasound as crucial in managing pregnancy. However, there is a notable discrepancy in the perceived skills between physicians and midwives/nurses, especially in basic obstetric ultrasound examinations. A majority of health professionals reported either no skills or low-level skills in assessing various aspects like cervical length, fetal heart (four-chamber views), aorta, pulmonary artery and Doppler (umbilical artery). The study suggests that improving access and utilization of obstetric ultrasound could be achieved through increased availability of quality ultrasound machines and enhanced training. Physicians expressed a stronger belief in the positive impact of more ultrasound machines, better machine quality, additional training for current ultrasound examiners and more physicians trained in ultrasound. The data underscores the potential for enhancing obstetric ultrasound provision in Tanzania by investing in better technology, providing more training for healthcare professionals and increasing the number of physicians skilled in ultrasound use. Furthermore, the study recommends targeted training for midwives to enhance their proficiency in basic obstetric ultrasound, ultimately contributing to improved accessibility and utilization of obstetric ultrasound in maternity care in Tanzania.
