Description of intervention(s) / exposure
Women who have undergone elective hysterectomy for benign disease when aged less than 51 years at the Royal Women's Hospital between 01/01/2008 - 31/07/2015 will be contacted to complete a survey. This asks about their experience of relief and regret regarding their hysterectomy as well as demographic data, medical and symptom history, current levels of stress and anxiety and personality trait. The survey will take approximately 30 minutes to complete. This survey has been self constructed with advice from gynaecologists and a psychologist as no pre-existing survey fit for our purpose existed. It does incorporate two validated questionnaires, the DASS-21, to measure depression, anxiety and stress and the 10-item neuroticism subscale of the International Personality Item Pool (IPIP-NEO) to assess the personality trait of neuroticism.

Eligibility
Key inclusion criteria
• All women who have undergone elective hysterectomy for benign disease in a general gynaecology unit at the Royal Women’s Hospital (Gynaecology Units 1, 2 and 3)
• Age <51 at time of surgery (this will include a range of ages for whom fertility is a possible issue and for whom fertility is not an issue and will target a mostly pre-menopausal population. With the exception of prolapse surgery the reasons for which hysterectomy is undertaken and pathologies detected differ in a menopausal group)
• Any type of hysterectomy included (total/subtotal; vaginal/ abdominal/ laparoscopic)
• Hysterectomy performed from 01/01/2008 – 31/07/2015 inclusive (as we want to allow at least 3 years of time from surgery to allow for long-term reflection on the decision)
Minimum age
18 Years
Maximum age
50 Years
Sex
Females
Can healthy volunteers participate?
No
Key exclusion criteria
• Indication for hysterectomy was malignancy or suspected malignancy including endometrial hyperplasia
• Hysterectomy performed as unplanned/emergency procedure
• Caesarean hysterectomy
• Non-English speaking

Statistical methods / analysis
1362 women aged <51 years underwent hysterectomy from 2008 – 2015 inclusive under the three general gynaecology units at the Royal Women’s Hospital. Of the 1362 women 110 were aged <36 at the time of hysterectomy. Once those with diagnoses of endometrial hyperplasia and endometrial cancer are excluded there will approximately 1250 women eligible to participate. The mean age of those eligible to participate in this study is 43 years, with standard deviation of 4.87. Using STATA V15 a sample size of 128 participants is required to detect a 2.5 year difference (half a standard deviation) in mean age between those who do and don’t report regret regarding hysterectomy with power=0.8 and alpha=0.05. While 128 is the minimum number to assess a 2.5 year difference in age in those who regret vs don’t we would also like to be able to assess the associations and interactions of other confounders such as: age, parity, neuroticism, psychological morbidity, history of abuse, indication for hysterectomy, desire for future fertility and symptom resolution following hysterectomy using logistic regression. Using a conservative estimate that 50 observations (or participants) are required per variable examined in the logistic regression [1], a sample size of 450 participants will allow us to examine at least 9 variables for their association and interaction(s) with relief and regret. We therefore aim for a sample size of 450 participants, with 128 minimum for assessment of the primary outcome of age and regret.

At completion of the study analysis will involve comparing categorical outcomes such as presence of previous general and gynaecological conditions using Chi squared tests and comparing continuous variables such as parity and various scales in the questionnaire measures using t-tests. If the data does not have a normal distribution then a non-parametric tests such as the Mann Whitney U test will be used. We will use ordinal logistic regression modelling to assess the effects of age and parity on relief and regret in this cohort. We will use regression modelling to assess the interactions of potential variables of interest associated with relief or regret (such as neuroticism, depression, indication for hysterectomy, fertility plans, experience of abuse and symptom response to surgery). P value of <0.05 will be considered significant.
