Transvaginal Sonography: perception and attitude of Nigerian women

The role of the sonographer - An investigation into the scope of practice for the sonographer internationally

INTRODUCTION

There is global variance in the role of a practicing sonographer. Literature examining global sonographic roles and scope of practice is limited, despite the international applicability of ultrasound imaging. This study aimed to examine the common and divergent features of a practicing sonographer internationally, and their impact upon the development of a global standard of practice.

METHODS

An ethically approved mixed-methods online survey was conducted. The purposive sample included all 75 current elected council members of the ISRRT [International Society of Radiographers and Radiological Technologists], an international professional organisation.

RESULTS

Thirty-six individuals from at least 32 different countries responded, reflecting the sonography profession in all four ISRRT regions. The results suggest that sonographer education requirements differ widely, from on the job training (16%, 6/36) to undergraduate or postgraduate schooling (44%, 16/36). Registration and accreditation bodies were present in the jurisdiction of 41% (14/34) and 35% (12/33) of respondents respectively, though many were voluntary, physician-focused or non-specific to sonographers. Five of 11 (45%) respondents suggested that the sonographer-radiologist relationship is individual-dependent, and not primarily positive or negative. Ten of 28 (36%) suggested that other professionals do not know the role of the sonographer.

CONCLUSION

The majority of ISRRT council member respondents believe that an international scope of practice could benefit and be implemented in their jurisdiction (26/28, 93% and 22/33, 67%). The key advantages noted were standardisation of education and improved professional mobility. However, lack of sonographer education and radiologist acceptance are important potential barriers.

IMPLICATIONS FOR PRACTICE

An international scope of practice could be beneficial and implementable in most ISRRT jurisdictions. Professional mobility and education standardization are the primary advantages. Insufficient sonographer education and physician acceptance are the key potential obstacles.

Mid-trimester cervical length not associated with HIV status among pregnant women in Botswana

Objective

HIV-infected women on antiretroviral therapy have a higher risk of preterm birth than HIV-uninfected women in Botswana. To better understand the mechanism for preterm birth among HIV-infected women, we evaluated whether mid-trimester cervical length differed by HIV status as cervical shortening is associated with an increased risk for preterm birth.

Methods

We conducted a prospective cohort study among pregnant women receiving care at the Scottish Livingstone Hospital in Molepolole, Botswana. Consecutive women referred for routine obstetrical ultrasound were consented and enrolled if between 22w0d and 24w6d by ultrasound biometry. Blinded to maternal HIV status, an obstetrician measured transvaginal cervical length using standardized criteria. Cervical length, as well as the proportion of women with a short cervix (<25mm), were compared among HIV-infected and HIV-uninfected women. The acceptability of transvaginal ultrasound was also evaluated.

Results

Between April 2016 and April 2017, 853 women presenting for obstetric ultrasound were screened, 187 (22%) met eligibility criteria, and 179 (96%) were enrolled. Of those enrolled, 50 (28%) were HIV-infected (86% on antiretroviral therapy), 127 (71%) were HIV-uninfected, and 2 (1%) had unknown HIV status. There was no significant difference in mean cervical length between HIV-infected and HIV-uninfected women (32mm vs 31mm, p = 0.21), or in the proportion with a short cervix (10% vs 14%, p = 0.44). Acceptability data was available for 115 women who underwent a transvaginal ultrasound exam. Of these, 112 of 115 (97%) women deemed the transvaginal scan acceptable.

Conclusions

The increased risk of preterm birth observed among HIV-infected women receiving antiretroviral therapy in Botswana is unlikely associated with mid-trimester cervical shortening. Further research is needed to understand the underlying mechanism for preterm birth among HIV-infected women.

Intimate patient examinations: The awareness, acceptance and practice preference of transvaginal ultrasound scan among women in a South-southern State of Nigeria

Background

Transvaginal ultrasound scan (TVS) is a relatively new routine intimate examination in Nigeria carried out only in fertility clinics, specialist radio-diagnostic centres and a few public hospitals. It is a procedure, which many patients find intrusive and may result in anxiety. The gender of the practitioner and the presence of a third person in the room may influence patient's acceptance to undergo the procedure. Centres offering this service do not routinely ask for the patient's opinion, which negates the patient-centred care principle. The aim of this study is to assess women's awareness, acceptance and practice preference of TVS to get their opinion about the preferred gender of sonologist and presence of a third person during the procedure in comparison to other intimate examinations.

Materials and Methods

It is a questionnaire-based prospective survey involving women referred for various indications to the radiology department of a Navy Hospital in south-southern Nigeria for 1 month.

Results

We recruited 204 women. Although only 20.6% knew about TVS, 98.5% accepted to undergo TVS. Forty-six percent were indifferent about the gender of the sonologist, while 45% and 9% preferred a female and a male, respectively. About 50.3% wanted a third person in the room during the TVS and majority preferred their husbands (44.7%) to a chaperone (35.8%).

Conclusion

The awareness of TVS is low, but it enjoys wide acceptance. Patient's preference for practitioner's gender and chaperone use are variable similar to findings from other intimate examinations, so consent should be sought before the procedure.
