Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention being examined is the use of a single use compared with a reusable hysteroscope in the context of outpatient diagnostic hysteroscopy procedures.

Participants will be recruited from the outpatient hysteroscopy service prior to or on the day of planned procedure. After screening the medical record ensuring conditions of inclusion and exclusion criteria are met, a member of the research team or clinician will gain informed consent from the participant and complete the enrolment form. Once enrolled in the study and after consent, participants will be randomly allocated 1:1 to have outpatient hysteroscopy using the single use device or conventional outpatient hysteroscopy. The procedure will be performed by a consultant gynaecologist from the Endosurgery Unit or a RANZCOG trainee level 5 or above who has performed at least 10 outpatient hysteroscopies in the preceding 12 months. Hysteroscopy will be performed using either conventional hysteroscopic device or single use device using a vaginoscopic approach where the hysteroscope is passed through the vagina and into the cervical canal using normal saline as distension medium. If a vaginoscopic technique is unsuccessful, local anaesthetic spray to the cervix or injection for intracervical or paracervical block may be administered to allow cervical dilatation for access the cavity. The findings at hysteroscopy are documented with intraoperative photographs. Any additional procedures such as removal of an endometrial polyp, endometrial sampling or an intrauterine device (IUD) insertion may be performed once hysteroscope is complete. Information for any operative procedure, sampling or IUD insertion will not be analysed for the purpose of this study, only the information for the diagnostic hysteroscopy procedure will be assessed. The procedure takes approximately 5-10 minutes.

For patients allocated to have their procedure with a single use hysteroscope, this will be performed with LiNA OperaScope. The LiNA OperaScope is a single-use, battery operated hysteroscopy device with a Liquid-crystal (LCD) display. It comes in a sterilised set with separate instruments available for biopsy and polyp removal available. A recording module can use used alongside the hysteroscope to allow for image capture and video recording of the procedure.

An operative report is documented for every procedure performed. For the purposes of the study, an audit of all reusable and disposable items will be recorded.
Intervention code [1] 330053 0
Diagnosis / Prognosis
Comparator / control treatment
The comparator for the single use device is a reusable outpatient hysteroscope.

If patients are allocated to conventional outpatient hysteroscopy, hysteroscopy will be performed utilising a reusable 3mm scope with a 4mm sheath, reusable camera and light lead which connect to a stack with a recording module. The procedure will be performed as described in the intervention arm.

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once a participant is enrolled in the study, they will be randomised via the RedCap module to either the single use or reusable group. Allocation will be concealed by a computerised central randomisation system in RedCap so that the enrolling clinician will not have access to the randomisation sequence. Once randomised, the clinician performing the hysteroscopy will be advised of the allocation for the participant via email.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be created using a module within RedCap by a member of the study team who will not be performing participant recruitment. This allocation sequence will be utilised within RedCap to allocate participants to either arm of the study once recruited.

Efficacy
Statistical methods / analysis
Procedure success rate will be reported as a proportion of total recruitment numbers (rate). Other demographic data, procedural information, patient and clinician survey data will be reported as univariate analysis using proportions (rates) and continuous variables reported with means (standard deviations).
If clinical equivalence is not demonstrated, no further evaluation will take place. If clinical equivalence is demonstrated, the data from the evaluation will be used to populate a cost-effectiveness model. The base case for the model is a hypothetical small gynaecological unit performing 72 outpatient hysteroscopies per year, six every month. Costs will be calculated from the hospital perspective and include costs of setup, individual procedure costs and any post-procedure device sterilisation required. In addition, for a failed procedure, the cost of an inpatient hysteroscopic procedure will be added. Effectiveness will be modelled using a combined patient and clinician rating of the procedure. The time horizon for the model will be set at one year, no discounting will be required due to the relatively short time horizon. Treeage software will be used to develop and run the model. All model inputs will be varied in sensitivity analysis to address potential for uncertainty.
