Dangers in the dark: Calling for a safer practice of transvaginal ultrasonography

How Frequently Is Ultrasound Required to Diagnose Polycystic Ovary Syndrome in a Clinical Population?

Background: Polycystic ovary syndrome (PCOS) is a common endocrine condition, affecting up to 20% of reproductive aged women worldwide. Polycystic ovarian morphology (PCOM) may be present, but is not required for diagnosis. Our study seeks to evaluate the utility of ultrasound in diagnosing or excluding PCOS by 2023 International Guidelines Criteria. Materials and Methods: Subjects were patients seen in a tertiary care referral clinic in whom other causes of hyperandrogenism (HA) were ruled out. All underwent complete history, physical, modified Ferriman Gallwey scoring, and serum androgen testing; followed by transvaginal ultrasound (TVUS) to assess ovarian morphology if indicated. PCOM was identified as antral follicle count ≥20 and/or ovarian volume >10 mL in at least one ovary. After clinical classification, PCOS was diagnosed by at least two of three: biochemical/clinical HA, ovulatory dysfunction (OD), and PCOM. Statistics were calculated using Fisher's exact test and chi-square. Results: In total, 454 subjects were included. 299 were classified as group A/B and did not require TVUS for diagnosis. Of 82 subjects with HA alone, 50 (61.0%) were classified as group C after demonstrating PCOM. Fifty-five subjects had OD alone, 37 (67.3%) of which were classified as group D based on PCOM. In total, 137/454, or 30.2% of subjects required TVUS for diagnosis or exclusion of PCOS. Conclusions: TVUS was necessary in less than one-third of subjects, primarily identifying PCOS groups C or D. Selective use of ovarian ultrasonography may reduce the costs and complexity of epidemiological and clinical studies for PCOS.

Regulation of the sonography profession and patient safety: A comparative study between Australia and New Zealand with implications for statutory regulation

INTRODUCTION

The primary aim of statutory regulation in healthcare is patient safety. Few studies examine health professionals' perceptions of statutory regulation and its impact on patient safety. Statutory regulation of sonographers is different in Australia and New Zealand which affords a unique opportunity to compare and contrast regulation and its impact.

METHODS

An interpretive policy analysis investigated how statutory regulation in the sonography profession addresses patient safety in Australia and New Zealand. A framework analysis explored relevant statutory regulatory policy as well as interviews from sonographers.

RESULTS

Four policy documents were included. Thirty-one sonographers in Australia and nine in New Zealand took part in semi-structured interviews. Four themes described statutory regulation and its impact on patient safety: how statutory regulation is implemented in practice to address patient safety; factors contributing to implementation of statutory regulation; impact of statutory regulation on sonographers; and considerations for regulation.

CONCLUSION

Statutory regulation provides a reference point for safe practice but can be non-specific in defining sonographers' roles and outlining strategies that address patient safety. Sonographers' perspectives of how regulation of practice addresses patient safety was mixed. A gap exists in sonographers' understanding of the role of statutory regulation in patient safety.

IMPLICATIONS FOR PRACTICE

Regulatory authorities must consider how to effectively engage and educate both patients and practitioners about their role in patient safety. Practitioners should also take the opportunity to engage in understanding the role of statutory regulation in enhancing patient safety. A broader view of how Fitness-to-Practice in sonography is managed should be considered in light of the findings.

Comparison of transvaginal ultrasound utilization between radiology and point of care ultrasound in first trimester pregnancy

BACKGROUND

Transvaginal (TVUS) and transabdominal ultrasound (TAUS) are both utilized in the evaluation of early pregnancy patients. While many practitioners using point of care ultrasound (POCUS) will generally not pursue TVUS in cases where an intrauterine pregnancy (IUP) is visualized on TAUS, this may not be true in Radiology performed ultrasound.

OBJECTIVES

To evaluate for differences in transvaginal ultrasound (TVUS) utilization between Radiology performed (RP) ultrasound and point of care ultrasound (POCUS) by Emergency Department (ED) physicians in early pregnancy patients. Secondarily, to assess length of stay (LOS) differences and the impact of specialized emergency ultrasound training on TVUS utilization.

METHODS

This was a retrospective study at a single academic ED. Study population was all ED patients who underwent first trimester ultrasound during the one year period of March 1, 2021 to February 28, 2022. Variables evaluated were chief complaint, gestational age, LOS, TAUS and TVUS utilization, ultrasound findings, and ultrasound specialty training of the ED physician.

RESULTS

There were 133 cases of POCUS ultrasound and 254 cases of RP ultrasound. All cases had TAUS imaging performed. Median LOS for patients when POCUS was utilized was 207 min (IQR 151-294) and 258 min (IQR 208-328) for those only using RP ultrasound, p ≤ 0.001. In the POCUS cohort, 38% (95% CI 30%-46%) received TVUS, while 94% received TVUS in the RP cohort (95% CI 90%-96%), p ≤ 0.001. Patients seen by ED faculty with ultrasound specialty training had TVUS 53% of the time (95% CI 41%-65%), while those seen by other ED faculty had TVUS 79% (95% CI 74%-83%) of the time, p = 0.035.

CONCLUSION

POCUS in early pregnancy is associated with a significant reduction in TVUS usage. We suspect that POCUS users elect not to pursue TVUS after an IUP is identified on TAUS, while technicians perform protocol-based TVUS irrespective of TAUS findings. Patients seen by ultrasound trained ED physicians are less likely to receive TVUS.

Liability, risks, and recommendations for ultrasound use in the diagnosis of obstetrics diseases

This literature review will summarize the liability issues, risks, and ultrasound recommendations for diagnosing obstetrics diseases. One liability issue is related to misdiagnosis or failure to detect abnormalities during an ultrasound examination. Ultrasound images can be subjective interpretations, and errors may occur due to factors such as operator skill, equipment limitations, or fetal positioning. Another liability concern is related to the potential adverse effects of ultrasound exposure on both the mother and fetus. While extensive research has shown that diagnostic ultrasound is generally safe when used appropriately, there are still uncertainties regarding long-term effects. Some studies suggest a possible association between prolonged or excessive exposure to ultrasound waves and adverse outcomes such as low birth weight, developmental delays, or hearing impairment. Additionally, obtaining informed consent from patients is crucial in mitigating liability risks. Patients should be informed about the purpose of the ultrasound examination, its benefits, limitations, potential risks (even if minimal), and any alternative diagnostic options available. This ensures that patients know the procedure and can make informed decisions about their healthcare. Proper documentation helps establish a clear record of the care provided and can serve as evidence in any legal disputes.

Exploring the lived experiences of debilitating period pain management in the UK

Background

Five to ten percent of women experience period pains that disrupt their lives yet 4 in 5 women believe that their claims for their dysmenorrhea are not taken seriously. Within the process of seeking support and understanding about their pain, they face various barriers that prevent them from finding the answers they deserve.

Methods

Semi-structured interviews were conducted with 8 women aged 20-28 to discuss their experiences with dysmenorrhea throughout their time since menarche.

Results

Using Scheper-Hughes and Lock understanding of the mindful body, this research explores women's experiences of dysmenorrhea through their physical body (relationship with the body and needing control), the social body (cultural concepts and comparisons to others) and the body politic (medicalisation, the medical team and the transvaginal ultrasound).

Conclusions

The impact of these aspects of their mindful bodies developed arguments showing how different actors had an impact on preventing them obtaining the patient-centred care they required without resistance. More must be done to honour the experience of pain women have regarding their periods, especially by healthcare professionals. There must be consistency in the way women are approached for their dysmenorrhea to prevent discrepancies of support. This must be done with clearer guidance on what is offered to women with dysmenorrhea, especially in the primary care setting.

Australian sonographers' perceptions of patient safety in ultrasound imaging: Part two - translation into practice

Introduction

A lack of patient safety research hampers capacity to improve safety in healthcare.Ultrasound is often considered 'safe' as it does not use ionising radiation, a simplistic view of patient safety. Understanding sonographers' actions towards patient safety is crucial; however, self-reported measures cannot always predict behaviour. This study is part of a PhD exploring patient safety in medical diagnostic ultrasound. The aim of this paper is to explore sonographers' responses to the patient safety concerns identified in Part one of this study. The ultimate aim of the study is to inform the final phase of the doctoral study which will consider the next steps in improving the quality and safety of healthcare experienced by patients.

Methods

A qualitative study using semi-structured, one-on-one interviews. The Theory of Planned Behaviour (TPB) explained how sonographers respond to perceived patient safety risks in practice.

Results

Thirty-one sonographers were interviewed. Based on the seven themes identified in Part one of the study, results showed that incongruences exist between identifying patient safety risks and the actions taken in practice to manage these risks.

Conclusion

The TPB showed that behavioural, normative and control beliefs impact sonographers' responses to perceived patient safety risks in practice and can lead to risk avoidance. Lack of regulation in ultrasound creates a challenge in dealing with Fitness to Practice issues. Collective actions are required to support sonographers in taking appropriate actions to enhance patient safety from multiple stakeholders including accreditation bodies, regulatory authorities, educational institutions and employers.

Australian sonographers' perceptions of patient safety in ultrasound imaging: Part 1 - identifying the main safety concerns, a qualitative study

Introduction

Patient safety has been an undervalued component of quality healthcare but is a challenging area of research.Ultrasound is the most common imaging modality in the world. Research on patient safety in ultrasound is generally focused on bioeffects and safe operation of ultrasound equipment. However, other safety issues exist in practice that warrant consideration.This paper forms the first part of a PhD study exploring patient safety in medical diagnostic ultrasound, beyond the notion of bioeffects.The ultimate aim of the study is to inform the final phase of the research study which will consider the next steps in improving the quality and safety of healthcare experienced by patients.

Methods

A qualitative study using semi-structured, one-on-one interviews. A thematic analysis categorised data into codes and generated final themes.

Results

A heterogeneous mix of 31 sonographers, who reflected the profile of the profession in Australia, were interviewed between September 2019 and January 2020. Seven themes emerged from the analysis. These were bioeffects, physical safety, workload, reporting, professionalism, intimate examinations and infection control.

Conclusion

This study presents a comprehensive analysis of sonographers' perceptions of patient safety in ultrasound imaging, not previously available in the literature. Consistent with the literature, patient safety in ultrasound tends to be viewed in technical terms through the potential for bioeffects of tissue damage or physical harm to the patient. However, other patient safety issues have emerged, and while not as well recognised, have the potential to negatively impact on patient safety.
