Outpatient hysteroscopy: Suitable for all? A retrospective cohort study of safety, success and acceptability in Australia

Abstract

Background

In Australia, gynaecologists continue to assess and investigate abnormal uterine bleeding with inpatient hysteroscopy despite evidence validating outpatient hysteroscopy services.

Aim

This retrospective cohort study assessed the safety, success and acceptability of office hysteroscopy in a gynae-oncology rapid-access clinic over six years in Sydney, Australia, and included all women without an age or body mass index (BMI) cut-off using a ‘see and treat’ concept.

Methods

A database was created and analysed retrospectively for patients who attended office hysteroscopy service between January 2016 and March 2021 (63 months, 481 eligible). An anonymous modified PAT-32 patient satisfaction questionnaire was also offered to an initial cohort after their procedure to gauge insightful feedback about acceptability.

Results

A total of 92% of patients had successful outpatient hysteroscopic access; 24% of cases required hysteroscopy under general anaesthesia (GA) despite pathology in over 50% of cases; 68% of the total were able to be managed with outpatient hysteroscopy and did not require a follow-up GA hysteroscopy. This paper is also the first of its kind to our knowledge to incorporate patients >65 years, those with a BMI >35 and those with a history of cervical stenosis. This study suggests that age and BMI do not impact the success rate of the procedure.

Conclusion

This study demonstrates that outpatient hysteroscopy is an acceptable, safe procedure that is well tolerated by patients. Considering our rapid-access hysteroscopy service allowed 68% of the patient cohort to avoid hysteroscopy under GA, we estimate conservatively ~$63 million per year in Australia could be saved by performing office hysteroscopies.
