Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Endometriosis, one of the most common diseases of women during their reproductive period., may present a chronic disabling disease with major impact on women's life. Therapeutic options are limited and recurrence of disease symptoms is frequent.

The current study investigates the quality of life and several risk factors for the development of endometriosis as well as satisfaction with medical support in a minimum of 600 women with different stages of endometriosis and the same number of control women matched for age (± 3 years) and nationality. To evaluate specific features of endometriosis-associated pain a second group of 100 women with chronic abdominal/pelvic pain not related to endometriosis is investigated. Recruitment takes place in different university clinics, and districts hospitals in Switzerland, Germany. And Austria. Control women i.e. women without any evidence for endometriosis presenting for annual routine gynaecological controls are collected at the same places.

A composition of different internationally validated questionnaires as well as specific questions on dealing with endometriosis is used to collect information on the quality of life and potential risk factors for endometriosis. Questions on sexuality and partnership are also distributed to women's partners. All diagnosis of endometriosis and classification of ASRM (American Society for Reproductive Medicine) disease stages are based on woman's medical charts.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

With a prevalence of 7-10% endometriosis is one of the most common diseases of women during their reproductive period. There is a broad range of clinical symptoms of endometriosis, which may vary between an incidental asymptomatic finding and a chronic severely painful disease. Symptoms are nearly independent from disease stage and current therapeutic options do not permit to reliably reduce symptoms to an acceptable level. Independent from the therapy chosen, about 20% of women re-develop clinical symptoms in the first year and another 50% within a period of five years.

The currently provided medical support concentrates on surgical and medical i.e. hormonal options. Although it seems evident that endometriosis-associated pain will have a serious impact on the daily life of women attaint and there is a broad literature on the effect of other chronic pain diseases on patients' lives, comparable data for endometriosis are rare. Also, support models to allow women to integrate a chronic endometriosis into their daily life are currently lacking. To provide a reliable basis for the development of better holistic support models, the current study collects data on different aspects of the quality of life in a minimum of 600 women with different stages of endometriosis and a minimum of 600 control women matched for age (± 3 years) and nationality. To evaluate which features of the quality of life are specific for endometriosis a second control group of 100 women with chronic abdominal/pelvic pain not related to endometriosis is investigated. Recruitment takes place in different university clinics, and districts hospitals in Switzerland, Germany and Austria. Control women i.e. women without any evidence for endometriosis presenting for annual routine gynaecological controls are collected at the same places.

A composition of different internationally validated questionnaires as well as specific questions on dealing with endometriosis is used to collect information on the quality of life and potential risk factors for endometriosis. The questionnaire includes basic socio-demographic data, life style parameters, a general as well as gynaeco-obstetric history including detailed questions on the diagnosis, treatment and current symptoms of endometriosis. In addition questionnaires on pain (modified version of the Brief Pain Inventory (BPI), Pain Disability Index (PDI), resources (SOC), stress perception (PSQ20), professional development, satisfaction with medical support, adverse childhood experiences (modified version of the childhood trauma questionnaire (CTQ), daily life, partnership (Partnerschaftsfragebogen, PFB), sexuality (modified version of the Brief Index of Sexual Functioning and Global sexual functioning) and anxiety/depression (PHQ, GAD) have to be completed by study participants. Socio-demographic questions, questions on partnership as well as on the estimated impact of endometriosis on partnership /sexuality were also given to study participants' partners. In addition to the current quality of life potential risk factors for the development of endometriosis e.g. traumatic childhood experiences are evaluated as well as satisfaction with medical support are evaluated.

All diagnosis of endometriosis and classification of ASRM disease stages are based on woman's medical charts.
