Részletes leírás
The proposed study is a double-blind, placebo-controlled randomized controlled trial (RCT). Participants will be recruited from Mount Sinai Hospital outpatient gynecology clinics. Recruitment, consent, randomization, procedure and post-procedure survey will occur during the same visit.
Two separate randomization schedules will be generated, one for IUD insertion and one for endometrial biopsy, using computer-generated sequences prepared by an independent study coordinator. Randomization will occur via consecutively numbered, opaque, sealed envelopes containing the allocation code. Each participant will be randomly assigned to one of two arms: 1) Intervention (5g of 2.5% lidocaine/2.5% prilocaine cream in a pre-filled vaginal applicator). 2) Placebo (5g of VersaPro cream in a pre-filled vaginal applicator). The research coordinator (who is not involved in direct patient care) will open the allocation envelopes without the presence of the participant or the provider. They will prepare the self-applicators with either 5g of 2.5% lidocaine/2.5% prilocaine cream or 5g of placebo cream to maintain blinding. The patient will be instructed how to self-administer the applicator and dispense all 5g of cream into their vagina in the washroom. A patient education sheet highlighting instructions will also be provided. The patient will wait 10-15 mins and then will be brought into a room for the procedure. Once the procedure begins, pain scores at key intervals will be patient-reported by a 10-point numeric rating scale (NRS) and recorded by a research assistant. A global pain score using a 100mm visual analogue scale (VAS) at 5-minutes following the procedure will also be collected. Post-procedure, there will be a provider-completed questionnaire and a patient satisfaction questionnaire. The provider questionnaire will help describe details of the procedure and complications. The patient satisfaction questionnaire will describe feasibility, acceptability and satisfaction with self-administered cream. The primary outcome will be global pain score at 5-minutes post-procedure, which will be patient-reported by the 100 mm VAS. Secondary outcomes include: pain at specific pain points using a 10-point NRA (baseline after insertion of cream, after insertion of speculum, tenaculum placement, sounding of uterus (IUD only), IUD insertion or endometrial biopsy, and 1-minute post-procedure). Other secondary outcomes include pre- and post-procedure anxiety, procedural characteristics (uterine size, position, IUD type, number of biopsy passes), immediate complication and side effects, procedural difficulty, length of time to complete the procedure, and patient reported feasibility, acceptability, perceived control over pain and satisfaction.

Elsődleges eredményintézkedések
Eredménymérő |
Intézkedés leírása |
Időkeret |
|---|---|---|
|
Global pain score
Időkeret: Completed by patient 5-minutes post procedure.
|
Patient-reported pain measured using the 100-mm Visual Analogue Scale (VAS) 5 minutes following the procedure (endometrial biopsy or IUD insertion).
The VAS ranges from 0 mm (no pain) to 100 mm (worst pain imaginable), with higher scores indicating greater pain (a worse outcome).
|
Completed by patient 5-minutes post procedure.

Pain scores at specific pain points during procedure
Időkeret: During the procedure
|
Pain scores at specific pain points: baseline after insertion of cream, after insertion of the speculum, removal of excess cream with gauze, placement of tenaculum, sounding (IUD only), IUD insertion/endometrial biopsy, and 1-minute post-procedure, which will be patient-reported verbally during the procedure on a scale from 0 (i.e.
no pain) to 10 (worst pain imaginable).
When more than one biopsy pass is required, only pain after the first pass will be recorded.
|
During the procedure
|
|
Anxiety levels
Időkeret: After application of the cream and waiting for 10 minutes but before starting the procedure as well as at 1-minute after the procedure.
|
Patient-reported anxiety before and after the procedure, measured using a 5-point Likert scale ranging from 1 (very anxious) to 5 (very calm).
Higher scores indicate less anxiety (a better outcome).
|
After application of the cream and waiting for 10 minutes but before starting the procedure as well as at 1-minute after the procedure.
|
|
Immediate complications of endometrial biopsy and/or IUD insertion
Időkeret: Completed by the provider immediately after the procedure (within 30 mins post procedure).
|
Provider-reported immediate complications associated with the endometrial biopsy and/or IUD insertion, including difficulty of procedure, vasovagal reaction, vital sign changes, or other procedure-related complications.
This will be assessed by the presence or absence of specific procedure-related complications.
|
Completed by the provider immediately after the procedure (within 30 mins post procedure).
|
|
Difficulty of procedure
Időkeret: Completed by the provider immediately after the procedure (within 30 mins post procedure).
|
The difficulty of the procedure will be assessed with a Likert scale from 1 (least difficult) to 5 (most difficulty), provider reported.
|
Completed by the provider immediately after the procedure (within 30 mins post procedure).
|
|
Length of time for procedure completion
Időkeret: During the procedure
|
Time will be recorded via stopwatch
|
During the procedure
|
|
Patient-reported acceptability, feasibility, and satisfaction with vaginal cream self-administration
Időkeret: Completed by the patient immediately after the procedure (within 30 mins post procedure).
|
Patient-reported acceptability and satisfaction with self-administration will be assessed using a study-specific questionnaire evaluating ease and comfort of self-administration, perceived control, satisfaction with pain control and the self-application process, and willingness to use self-administration for a future gynecologic procedure. Ease of administration, comfort with self-administration, satisfaction with pain control, satisfaction with the self-application process, and likelihood of choosing self-administration again will each be assessed using 5-point Likert scales ranging from 1 to 5, with higher scores indicating greater ease, comfort, satisfaction, or likelihood of future use (a better outcome). Additional acceptability measures, including confidence in correct application, difficulty with application, perceived control, and willingness to choose the same pain-control method in the future, will be reported descriptively based on categorical responses (Yes/No/Unsure) |
Completed by the patient immediately after the procedure (within 30 mins post procedure).
