Abstract

Objectives To determine if a standardised method of leg positioning without stirrups reduces the physical discomfort and sense of vulnerability and increases the sense of control among women undergoing speculum examination as part of a routine gynaecological examination.

Design Randomised clinical trial.

Setting Family medicine outpatient clinic.

Patients 197 adult women undergoing routine gynaecological examination and cervical smear.

Intervention Examination with or without stirrups.

Main outcome measures Women's perceived levels of physical discomfort, sense of vulnerability, and sense of control during the examination, measured on 100 mm visual analogue scales.

Results Women undergoing examination without stirrups had a reduction in mean sense of vulnerability from 23.6 to 13.1 (95% confidence interval of the difference - 16.6 to - 4.4). Mean physical discomfort was reduced from 30.4 to 17.2 (- 19.7 to - 6.8). There was no significant reduction in sense of loss of control.

Conclusion Women should be able to have gynaecological examinations without using stirrups to reduce the stress associated with speculum examinations.

Introduction

Compliance rates with cervical screening vary, and embarrassment and fear of pain during examination have been reported as potential barriers to screening.13 Reducing these barriers may improve screening rates.3 Whereas in countries such as the United Kingdom, Australia, and New Zealand speculum examinations are done without stirrups with the woman in the dorsal or lateral positions, in the United States medical providers are trained to do gynaecological examinations with women in the dorsal lithotomy position in stirrups. We examined the use of an alternative positioning to improve women's experience with speculum examinations at routine gynaecological visits.

Methods

Assignment, masking, and flow—Women aged 3 18 years presenting for a routine gynaecological examination in a family medicine clinic were eligible for inclusion. We excluded women who were pregnant, had vaginal complaints, or were unable to consent for themselves. Participants were enrolled from January to August 2005. Women were randomised into “stirrup” and “no stirrup” groups by assigning study numbers to one of the two groups using an online random number generator and enclosing the assignments in envelopes. The envelopes were opened, revealing the method to be used, after the woman agreed to participate (fig 1). This study was powered to have an 80% chance of detecting a 5 mm difference in sense of vulnerability or discomfort, with an SD of 22 mm (determined by pilot study), on a 100 mm visual analogue scale. We originally intended to include 300 women but we stopped after a planned interim analysis of 200 patients.

Protocol—Patients in the control group were examined with their heels placed in uncovered metal stirrups at 30-45° angles to the examination table. The intervention group were examined with their feet placed on the corners of a fully deployed table extension. All women were draped with a full sized sheet in a standardised manner that maximised coverage of the woman and allowed visualisation of the perineum (fig 2). Medium Graves' plastic speculums and an external light source were used for all examinations.

Provider training—We recruited eight providers from within the clinic: five staff physicians, two resident physicians, and one family nurse practitioner (five men and three women). All providers were taught how to position and cover the women with a combination of individual teaching, still photographs, and a short video.

Outcomes measured—We collected demographic data for each participant. Race, as identified by the women from a list provided, was recorded because it has often been looked at in relation to satisfaction or compliance with cervical smears. Afterwards, women completed a questionnaire regarding the examination. We used 100 mm visual analogue scales to measure physical discomfort, sense of vulnerability, and sense of loss of control. Study identification numbers were used to preserve anonymity of the respondents. We had previously piloted the questionnaire on 25 women. We assessed the quality of smears according to adequacy and the presence or absence of endocervical cells reported in the pathology reports.

Data handling—Two researchers (DAS and DRJ) entered the demographic data and results of the smear tests on a spreadsheet. An independent observer measured and entered the visual analogue scores on a separate spreadsheet in a blinded manner.

Analysis—We used SPSS version 11.0 for analysis. In the preliminary analyses we used χ2 tests for categorical data and t tests for independent samples for continuous data. We tested the hypothesis with the t test for independent samples to determine differences in outcome variables.

Results

We recruited and randomised 204 women. After randomisation, seven women were removed from the study: five did not meet enrolment criteria (three were pregnant and two were adolescents), one woman had labial adhesions that prevented insertion of the speculum, and there was one equipment failure caused by a faulty stirrup. Table 1 shows the baseline characteristics of the remaining women (table 1).

Physical discomfort and sense of vulnerability were both significantly lower in the women examined without stirrups (table 2). Mean sense of vulnerability was 44% lower and mean physical discomfort was 43% lower. Sense of loss of control was not significantly different.

There were no significant differences in the quality of smears between the two groups. Only two smears were inadequate for evaluation (both from the no stirrups group, P = 0.16). Sixteen of the smears from the women examined without stirrups and 15 from the women examined with stirrups did not contain endocervical cells (P = 0.84).

Discussion

Women undergoing gynaecological examination without stirrups report less physical discomfort and a reduced sense of vulnerability than women in stirrups.

Weaknesses of this study

Our outcome variables were broad categories. When answering about physical discomfort, were women measuring pain from speculum insertion, leg position, or both? These outcomes will need to be more precisely defined in future research. Only eight providers from the same practice were involved in this study.

Meaning of this study

Given that over 50 million cervical smears are done each year in the US,4 any reduction in the associated physical and psychological stress should prompt a change in clinical practice provided there are no associated negative implications. Previous studies have provided anecdotal evidence that women prefer examinations done without stirrups.57

The technique without stirrups used in this study is easy to learn, simple to perform, and does not affect the adequacy of examinations. Though Curtis reported that his rate of adequate smears went up when he switched to examination with stirrups,8 our results suggest that examination without stirrups does not affect adequacy, though a larger study would be needed to confirm this.

A sense of vulnerability or defencelessness is one of the reasons why women dislike pelvic examinations.2 Once a woman's feet are placed in stirrups, getting out is neither quick nor easy. Stirrups suspend the feet in the air and greatly reduce the ability to manoeuvre, which may give women a sense of being unable to protect themselves from potential danger. Women undergoing a cervical smear without stirrups are much freer to adjust the position of their feet and hips during the examination. The method we used in this study allows considerable internal or external rotation of the hips and the knees as well as supination of the feet. Each woman can manoeuvre her legs and feet into the position that is most comfortable and relaxing for her.

The level of physical discomfort reported by the stirrup group was similar to that in a previous study done on women presenting with abdominal pain or vaginal bleeding.9 In that study, patients had an average pain score of 33.8 mm on similar a visual analogue scale when they were examined by a woman and 38.8 mm when examined by a man.

Various interventions to reduce the physical and psychological distress associated with speculum examinations have been studied. Alternative positions,10 alternative speculums,11 alternative foot rests,12 self insertion of the speculum,13 and different types of gowns14 have shown varying degrees of improvement in pain, embarrassment, or anxiety. Reduction of physical discomfort and psychological distress are part of the motivation for the recent attempts to validate self collection methods for cervical cancer screening to eliminate the need for smears.1516 Some studies have shown that beliefs about pain during the procedure can influence screening behaviours for some women.13

Respect for patients' preferences and ensuring physical comfort are core dimensions of patient centred care, one of the six domains of quality advocated by the Institute of Medicine.17 Our findings suggest that examination without stirrups represents a more patient centred way to perform speculum examinations.

What is already known on this topic

Speculum examinations to collect cervical smears are the most commonly performed procedures on women

Women dislike undergoing speculum examinations because of fear of pain, embarrassment, or anxiety about feeling vulnerable during the examination

What this study adds

Women feel less vulnerable and experience less discomfort when examination is carried out without stirrups
