A self-administered questionnaire to measure the painful symptoms of endometriosis: Results of a modified DELPHI survey of patients and physicians

Measurement of changes to the menstrual cycle: A transdisciplinary systematic review evaluating measure quality and utility for clinical trials

Despite the importance of menstruation and the menstrual cycle to health, human rights, and sociocultural and economic wellbeing, the study of menstrual health suffers from a lack of funding, and research remains fractured across many disciplines. We sought to systematically review validated approaches to measure four aspects of changes to the menstrual cycle-bleeding, blood, pain, and perceptions-caused by any source and used within any field. We then evaluated the measure quality and utility for clinical trials of the identified instruments. We searched MEDLINE, Embase, and four instrument databases and included peer-reviewed articles published between 2006 and 2023 that reported on the development or validation of instruments assessing menstrual changes using quantitative or mixed-methods methodology. From a total of 8,490 articles, 8,316 were excluded, yielding 174 articles reporting on 94 instruments. Almost half of articles were from the United States or United Kingdom and over half of instruments were only in English, Spanish, French, or Portuguese. Most instruments measured bleeding parameters, uterine pain, or perceptions, but few assessed characteristics of blood. Nearly 60% of instruments were developed for populations with menstrual or gynecologic disorders or symptoms. Most instruments had fair or good measure quality or clinical trial utility; however, most instruments lacked evidence on responsiveness, question sensitivity and/or transferability, and only three instruments had good scores of both quality and utility. Although we took a novel, transdisciplinary approach, our systematic review found important gaps in the literature and instrument landscape, pointing towards a need to examine the menstrual cycle in a more comprehensive, inclusive, and standardized way. Our findings can inform the development of new or modified instruments, which-if used across the many fields that study menstrual health and within clinical trials-can contribute to a more systemic and holistic understanding of menstruation and the menstrual cycle.

Development and early validation of questionnaires to assess system level factors affecting male partners' attendance at childbirth in LMICs

BACKGROUND

There is evidence that a woman who receives continuous labour support from a chosen companion can have shorter labour duration, is more likely to give birth without medical interventions, and report a satisfying childbirth experience. These outcomes result from the beneficial effects of emotional and practical support from the woman's chosen companion, and care provided by health providers. When a woman's chosen companion is her male partner, in addition to the above benefits, his presence can promote his bonding with the baby, and shared parenthood. However, there may be healthcare system barriers, including organisational, management and individual (staff) factors, that inhibit or restrict women's choice of companion. There are currently no suitable survey tools that can be used to assess the system level factors affecting the implementation of male partners' attendance at childbirth in low- and middle- income countries (LMICs).

METHODS

We designed two questionnaires to help to address that gap: the Male Partners' Attendance at Childbirth-Questionnaire for Heads of Maternity Units (MPAC-QHMUs); and the Male Partners' Attendance at Childbirth-Questionnaire for Maternity Staff (MPAC-QMS). We carried out an extensive review to generate initial items of the two questionnaires. We assessed the content and face validity of the two questionnaires in a three-round modified Delphi study.

RESULTS

The Male Partners' Attendance at Childbirth-Questionnaire for Heads of Maternity Units (MPAC-QHMUs) focused on organisational and management factors. The Male Partners' Attendance at Childbirth-Questionnaire of Maternity Staff (MPAC-QMS) focused on individual staff factors. The final MPAC-QHMUs and MPAC-QMS included items which garnered over 80% content relevance according to the experts' rating. After all three consensus rounds of the Delphi study, 43 items were retained for the MPAC-QHMUs and 61 items were retained for the MPAC-QMS.

CONCLUSIONS

The MPAC-QHMUs and the MPAC-QMS may help understanding of barriers affecting male partners' attendance at childbirth in LMICs in order to devise implementation strategies to enable wider availability and to maximize women's choices during labour and childbirth. The MPAC-QHMUs and the MPAC-QMS as newly-developed questionnaires require further validation of their acceptability and feasibility in different cultural contexts, and languages.

Validation of the Iranian version of the ENDOPAIN-4D questionnaire for measurement of painful symptoms of endometriosis

Endometriosis is one of the leading gynecological disorders in reproductive ages. About two-thirds of women with endometriosis experience chronic pelvic pain. There are different methods for the assessment of pain in endometriosis. One of these questionnaires is endometriosis painful symptoms-4 dimensions (ENDOPAIN-4D) questionnaire, which has not been validated in Iran. Therefore, we decided to conduct a study to determine the psychometric properties of this questionnaire. In this study, we randomly selected 169 women with endometriosis from two educational-medical centres of Al-Zahra and Taleghani in Tabriz, Iran, in 2020. We evaluated the validity of ENDOPAIN-4D in terms of face, content, and structure (through exploratory and confirmatory factor analyses). We used internal consistency assessment and test-retest reliability to determine the questionnaire reliability. In this study, the CVI and CVR for the ENDOPAIN-4D instrument were obtained as 0.99 and 0.98, respectively. In the exploratory factor analysis, we extracted a four-factor structure, and the confirmatory factor analysis gave a good fit for the extracted model. We obtained Cronbach's alpha coefficient as 0.96 and the intra-class correlation coefficient (ICC) (at 95% confidence interval) as 0.94 (0.85 to 0.98). The Persian version of ENDOPAIN-4D has acceptable content validity, construct validity and reliability for the evaluation of pelvic pain and gynaecology in Iranian women with endometriosis.Impact StatementWhat is already known on this subject? There are different methods for the assessment of pain in endometriosis. But there is no specific psychometric instrument to determine the painful symptoms of endometriosis in Iran so far.What do the results of this study add? The Persian version of ENDOPAIN-4D is a valid and reliable instrument for the evaluation of pelvic pain and gynaecology in Iranian women with endometriosis.What are the implications of these findings for clinical practice and/or future research? The validation of the Persian version of the ENDOPAIN-4D questionnaire leads to correct assessment of painful symptoms in Iranian women with endometriosis and will be useful in evaluating the patients' pain intensity and the response to treatment in practice.

A new validated screening method for endometriosis diagnosis based on patient questionnaires

BACKGROUND

The time between symptoms onset and endometriosis diagnosis is usually long. The negative impacts of delayed endometriosis diagnosis can affect patients and health outcomes.

METHODS

We conducted a case-control study using clinical symptoms and epidemiological data extracted from a prospective pre-operative patient questionnaire compared between patients with histologically proven endometriosis and patients with no endometriosis at surgical exploration from 2005 to 2018, in a French referral center. We used the beta coefficients of the significant variables introduced in a multiple regression model to devise a score (score 1), evaluated by the area under the curve (or C-index), with three levels, defined by a score between 1 and ≥ 25: (i) highly specific, identifying correctly the patients without the disease; (ii) highly sensitive, identifying the patients with the disease; and (iii) a level maximizing sensitivity and specificity for the best classification of the whole population. To minimize patient self-evaluation of pain, we devised a second score (score 2) with the same method and levels and scores definition, excluding visual analog scale pain scores, except for dysmenorrhea. These scores were validated on an internal and external population.

FINDINGS

Score 1 had a C-index of 0.81 (95% CI [0.79-0.83]). Results for the three score 1 levels were: ≥ 25: specificity of 91% (95% CI [89-93]); < 11: sensitivity of 91% (95% CI [89-93]); ≥ 18: specificity of 75% (95% CI [72-78]) and sensitivity of 73% (95% CI [70-76]). Score 2 had a C-index of 0.75 (95% CI [73-77]). The three levels of score 2 were: ≥ 24: specificity of 82% (95% CI [80-85]); < 7: sensitivity of 92% (95% CI [90-94]); ≥ 17: specificity of 62% (95% CI [58-65]) and sensitivity of 78% (95% CI [75-81]). The two scores were internally and externally validated.

INTERPRETATION

A score based only on a patient questionnaire could allow identification of a population at high risk of endometriosis. This strategy might help referral to specialized radiologists for a non-surgical endometriosis scan.

FUNDING

None.

Developing consensus on core outcome domains for assessing effectiveness in perioperative pain management: results of the PROMPT/IMI-PainCare Delphi Meeting

ABSTRACT

Postoperative pain management is still insufficient, leading to major deficits, including patient suffering, impaired surgical recovery, long-term opioid intake, and postsurgical chronic pain. Yet, identifying the best treatment options refers to a heterogeneous outcome assessment in clinical trials, not always reflecting relevant pain-related aspects after surgery and therefore hamper evidence synthesis. Establishing a core outcome set for perioperative pain management of acute pain after surgery may overcome such limitations. An international, stepwise consensus process on outcome domains ("what to measure") for pain management after surgery, eg, after total knee arthroplasty, sternotomy, breast surgery, and surgery related to endometriosis, was performed. The process, guided by a steering committee, involved 9 international stakeholder groups and patient representatives. The face-to-face meeting was prepared by systematic literature searches identifying common outcome domains for each of the 4 surgical procedures and included breakout group sessions, world-café formats, plenary panel discussions, and final voting. The panel finally suggested an overall core outcome set for perioperative pain management with 5 core outcome domains: physical function (for a condition-specific measurement), pain intensity at rest, pain intensity during activity, adverse events, and self-efficacy. Innovative aspects of this work were inclusion of the psychological domain self-efficacy, as well as the specific assessment of pain intensity during activity and physical function recommended to be assessed in a condition-specific manner. The IMI-PROMPT core outcome set seeks to improve assessing efficacy and effectiveness of perioperative pain management in any clinical and observational studies as well as in clinical practice.

Patient-Reported Outcome Measures in Endometriosis

Patient Reported Outcome Measures (PROM) evoke measurements that allow capturing patients’ perspectives on their condition. In endometriosis care, physicians’ understanding of the effect of the disease and the treatment on patients is often poor. The use of PROMs in endometriosis clinical practice can facilitate patient-provider communication and the implementation of patient-centered care, improve patients’ quality of life, as well as provide a tool for patients’ self-management of the disease. Today, PROMs are extensively used in research and clinical trials, however they are barely used in clinical practice. The development of digital tools facilitating capturing PROMs can contribute to their use by physicians in routine endometriosis care. However, all PROMs are not adapted to be used in routine care in the context of endometriosis. The objective of this study was to present a catalogue of available PROMs for routine endometriosis care and evaluate them according to selected criteria. To do so, we explored the different PROMs currently in the literature. Consequently, 48 PROM were identified as tools used to evaluate various dimensions of the impact of endometriosis on patients. The selected PROMs were evaluated for their potential to be used as a standard in clinical practice in endometriosis. The selected catalogue of PROMs is the starting point for the integration of digital tools to capture PROMs and the development of patient-centered dashboards to be used by patients and clinicians in endometriosis care and self-management to improve care processes, patient satisfaction, quality of life, and outcomes.

The effect of dydrogesterone on sexual function in endometriosis

Endometriosis is an oestrogen-dependent chronic disease, which is commonly regarded as a disease of reproductive-aged women. We aimed to evaluate the sexual function with Female Sexual Function Index (FSFI) in women with endometriosis who received dydrogesterone for 6 months. A total of 79 women with endometriomas were recruited in the study group and received 10 mg dydrogesterone tablets orally for 6 months. FSFI and visual analog scale (VAS) scores for each patient before and after treatment were recorded. When before treatment VAS scores and after treatment VAS scores (5.7 ± 1.27, 3.97 ± 1.01, respectively) were compared, a significant decrease was observed (p = .001). A significant increase in mean orgasm scores (3.23 ± 0.6 vs. 3.57 ± 0.65, p = .01) and means satisfaction scores (3.85 ± 0.48 vs. 4.10 ± 0.38, p < .001) were observed. In addition, means desire scores were also significantly higher following treatment (p = .01). In conclusion, this study showed that FSFI scores were increased after 6 months of dydrogesterone treatment in patients with endometriosis. Desire, satisfaction, orgasm and pain scores improved significantly, and sexual dysfunction decreased after treatment.Impact statementWhat is already known on this subject? Endometriosis is a chronic inflammatory disease associated with severe dysmenorrhoea, pelvic pain, dyspareunia, painful gastrointestinal symptoms and sub-fertility are among the symptoms. These symptoms can be responsible for a significant decrease in the quality of life scores of the patients. Dydrogesterone is a synthetic progesterone derivative, which suppresses oestrogen levels and ovulation. Dydrogesterone's effect on pain relief in endometriosis patients has already been shown, but it's role on the sexual dysfunction observed in women with endometriosis has not yet been questioned.What do the results of this study add? To the best of our knowledge this is the first study showing the effects of dydrogesterone on sexual function in patients with endometriosis.What are the implications of these findings for clinical practice and/or further research? Dydrogesterone can safely be used in medical treatment of endometriosis not only for pain relief but also patients with additional complaints such as sexual dysfunction can benefit from this treatment. Future studies with larger cohorts and long-term follow-ups are needed to validate our results.

Early identification of women with endometriosis by means of a simple patient-completed questionnaire screening tool: a diagnostic study

OBJECTIVES

To assess the value of a self-completed questionnaire based on patients' verbal descriptors of pelvic painful symptoms to identify women with endometriosis.

DESIGN

Prospective 1:2 nonmatched case-control study.

SETTING

Three French endometriosis referral centers.

PATIENT(S)

Endometriosis cases were women aged 18-45 years with endometriosis confirmed by histology. Controls were as follows: asymptomatic women attending a gynecologic consultation for routine examination; women without evidence of endometriosis consulting for pain/infertility; and population-based controls from the same urban locations.

INTERVENTION(S)

All women completed the 21-item yes/no questionnaire about painful symptoms.

MAIN OUTCOME MEASURE(S)

The area under the receiver operating characteristic curve of the full question set model based on binary logistic regression and the diagnostic accuracy of low- and high-risk classification rules based on selected threshold of the prediction model.

RESULT(S)

We included 105 cases and 197 controls (45 asymptomatic consultation-based controls, 66 women without endometriosis consulting for pain/infertility, and 86 population-based controls). The full question set prediction model, including age, had an area under the receiver operating characteristic curve of 0.92 (95% confidence interval, 0.87-0.95) after internal validation. The high-risk classification rule had a specificity of 98.0% and a positive likelihood ratio of 30.5. The low-risk classification rule had a sensitivity of 98.1% and a negative likelihood ratio of 0.03. For a hypothesized pretest prevalence of 10%, the high- and low-risk prediction rules ascertained endometriosis with posttest probability rates of 77.2% and 0.3%, respectively.

CONCLUSION(S)

A self-completed patient-centered questionnaire can identify women at low or high risk of endometriosis with a high diagnostic accuracy and, thus, may help early identification of women with endometriosis.

Constellations of pain: a qualitative study of the complexity of women's endometriosis-related pain

INTRODUCTION

Prior research into endometriosis-related pain has focused on specific aspects of the pain experience such as cyclical pain, emotional aspects of pain and certain types of pain such as dysmenorrhea and dyspareunia. However, research has paid less attention to the diversity and complexity of women's pain experiences, which can lead to failure to recognise some symptoms as part of endometriosis and poor symptom management.

METHODS

We conducted qualitative semi-structured face-to-face interviews with 20 women in the United Kingdom recruited from an endometriosis self-help group with a diagnosis of endometriosis via laparoscopy. A topic guide framed questions around experiences of pain. Interviews were audio-recorded and transcribed verbatim. Transcripts were analysed using inductive thematic analysis.

RESULTS

Women experienced multiple types of pain that they felt were caused by endometriosis and affected many different parts of the body including bowel, bladder, lungs, kidneys, nerves, upper body, lower limbs and head. These pains consisted of different conceptual categories: type, pattern and intensity. These categories came together to create a complex, interrelated experience for each individual that we termed 'constellations of pain' because each woman had a complex set of pain categories and no two individuals appeared to have the same pain experience.

CONCLUSION

The complexity and diversity of endometriosis-related pain found in this study has implications for improving diagnosis, medical and non-medical pain management and improving the clinical encounter between women and healthcare professionals.

The ENDOPAIN 4D Questionnaire: A New Validated Tool for Assessing Pain in Endometriosis

OBJECTIVES

To study the measurement properties, the responsiveness and the minimal clinically important difference of the ENDOPAIN-4D: a new questionnaire for assessing pain in endometriosis.

METHODS

A prospective, observational, multicentre study was conducted including all women ≥18 years consulting for symptomatic proven endometriosis between 1 January 2017 and 30 June 2018 and volunteering to participate. Each patient had to answer a new self-administered patient-reported outcome (PRO) questionnaires (the ENDOPAIN-4D) at inclusion (T0) and 12 months after medical or surgical treatment (T1). Criteria defined by COSMIN were used to validate the questionnaire's measurement properties. The minimal clinically important difference was estimated by the anchor-based method.

RESULTS

The study included 199 women. The ENDOPAIN-4D score had a four dimensional structure with good internal consistency (measured by Cronbach α): (I) pain-related disability (α = 0.79), (II) painful bowel symptoms (α = 0.80), (III) dyspareunia (α = 0.83), and (IV) painful urinary tract symptoms (α = 0.77). They produced four subscores that can be summed to obtain a single score (α = 0.61). The ENDOPAIN-4D total score ranged from 0 to 94.00 (mean ± SD: 46.7 ± 22). The total score was significantly correlated with the PROs used in endometriosis. Sensitivity to change was good with large effect sizes (ES) (mean of the differences: 36.3 p = 1.8 10-7, ES 0.76). The minimal clinically important difference of the global score was determined to be 10.9.

CONCLUSIONS

The ENDOPAIN-4D questionnaire is easy to use, valid, and effective in assessing patient reported pain symptoms in women treated for endometriosis. This new instrument can be used as the primary outcome for future clinical trials and as a tool for routine patient follow-up.

Dyspareunia in Their Own Words: A Qualitative Description of Endometriosis-Associated Sexual Pain

Introduction

Dyspareunia has been called the neglected symptom of endometriosis and is underexplored in clinical and research contexts. Understanding the physical experience and patient-important aspects of endometriosis-associated sexual pain can help advance valid measurement of this symptom.

Aims

The goal of this research was to characterize the physical experience of endometriosis-associated dyspareunia in the words of people affected by this condition.

Methods

This was a qualitative descriptive study that included participants with current or previous endometriosis-associated dyspareunia recruited from a data registry. Data collection involved semistructured interviews that began with an open-ended question about dyspareunia followed by prompts related to the nature of sexual pain.

Main Outcome Measures

Interviews transcripts were subjected to qualitative content analysis using a priori (pain site, onset, character, radiation, associations, time course, and exacerbating/relieving factors) and emergent themes.

Results

A total of 17 participants completed interviews. Mean participant age was 33.3 years and most were identified as white, college-educated, heterosexual, and partnered. Location, onset, and character were important; interrelated features of endometriosis-associated dyspareunia were: (i) introital pain began with initial penetration and had pulling, burning, and stinging qualities and (ii) pelvic pain was experienced with deep penetration or in certain positions and was described as sharp, stabbing, and cramping. Dyspareunia ranged from mild to severe, had a marked psychosocial impact for some participants, and was managed using a variety of treatments and strategies.

Conclusion

The endometriosis-associated dyspareunia experienced by participants was heterogenous in presentation, severity, and impact. Our findings have implications for the development of valid patient-reported outcome measures of this symptom.

Developing consensus on core outcome domains and measurement instruments for assessing effectiveness in perioperative pain management after sternotomy, breast cancer surgery, total knee arthroplasty, and surgery related to endometriosis : The IMI-PainCare PROMPT protocol for achieving a consensus on core outcome domains

INTRODUCTION

Evidence synthesis of clinical trials requires consistent outcome assessment. For pain management after surgery, inconsistency of effectiveness assessment is still observed. A subproject of IMI-PainCare (Innovative Medicine Initiatives, www.imi-paincare.eu ) aims for identifying core outcome domains and measurement instruments for postoperative pain in four surgical fields (sternotomy, breast cancer surgery, total knee arthroplasty, and surgery related to endometriosis) in order to harmonize outcome assessment for perioperative pain management.

METHODS

A multifaceted process will be performed according to existing guidelines (Core Outcome Measures in Effectiveness Trials (COMET), COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)). In a first step, outcome domains will be identified via systematic literature review and consented on during a 1-day consensus meeting by 10 stakeholder groups, including patient representatives, forming an IMI PROMPT consensus panel. In a second step, outcome measurement instruments regarding the beforehand consented core outcome domains and their psychometric properties will be searched for via systematic literature review and approved by COSMIN checklist for study quality and scale quality separately. In a three-step online survey, the IMI PROMPT consensus panel will vote for most suitable measurement instruments. The process is planned to be conducted between 11/2017 (systematic literature review on common outcome domains) and 3/2022 (final voting on core outcome measurement).

Polymorphisms and endometriosis: a systematic review and meta-analyses

BACKGROUND

Endometriosis is an estrogen-dependent gynecological disorder that affects at least 10% of women of reproductive age. It may lead to infertility and non-specific symptoms such as chronic pelvic pain. Endometriosis screening and diagnosis are difficult and time-consuming. Late diagnosis (with a delay ranging from 3.3 to 10.7 years) is a major problem and may contribute to disease progression and a worse response to treatment once initiated. Efficient screening tests might reduce this diagnostic delay. As endometriosis is presumed to be a complex disease with several genetic and non-genetic pathogenic factors, many researchers have sought to identify polymorphisms that predispose to this condition.

OBJECTIVE AND RATIONALE

We performed a systematic review and meta-analysis of the most regularly reported polymorphisms in order to identify those that might predispose to endometriosis and might thus be of value in screening.

SEARCH METHODS

The MEDLINE database was searched for English-language publications on DNA polymorphisms in endometriosis, with no date restriction. The PubTator text mining tool was used to extract gene names from the selected publications' abstracts. We only selected polymorphisms reported by at least three studies, having applied strict inclusion and exclusion criteria to their control populations. No stratification based on ethnicity was performed. All steps were carried out according to PRISMA guidelines.

OUTCOMES

The initial selection of 395 publications cited 242 different genes. Sixty-two genes (corresponding to 265 different polymorphisms) were cited at least in three publications. After the application of our other selection criteria (an original case-control study of endometriosis, a reported association between endometriosis and at least one polymorphism, data on women of reproductive age and a diagnosis of endometriosis in the cases established by surgery and/or MRI and confirmed by histology), 28 polymorphisms were eligible for meta-analysis. Only five of the 28 polymorphisms were found to be significantly associated with endometriosis: interferon gamma (IFNG) (CA) repeat, glutathione S-transferase mu 1 (GSTM1) null genotype, glutathione S-transferase pi 1 (GSTP1) rs1695 and wingless-type MMTV integration site family member 4 (WNT4) rs16826658 and rs2235529. Six others showed a significant trend towards an association: progesterone receptor (PGR) PROGINS, interCellular adhesion molecule 1 (ICAM1) rs1799969, aryl-hydrocarbon receptor repressor (AHRR) rs2292596, cytochrome family 17 subfamily A polypeptide 1 (CYP17A1) rs743572, CYP2C19 rs4244285 and peroxisome proliferator-activated receptor gamma (PPARG) rs1801282), and 12 showed a significant trend towards the lack of an association: tumor necrosis factor (TNF) rs1799964, interleukin 6 (IL6) rs1800796, transforming growth factor beta 1 (TGFB1) rs1800469, estrogen receptor 1 (ESR1) rs2234693, PGR rs10895068, FSH receptor (FSHR) rs6166, ICAM1 rs5498, CYP1A1 rs4646903, CYP19A1 rs10046, tumor protein 53 (TP53) rs1042522, X-ray repair complementing defective repair in Chinese hamster cells 1 (XRCC1) rs25487 and serpin peptidase inhibitor clade E member 1 (SERPINE1) rs1799889; however, for the 18 polymorphisms identified in the latter two groups, further studies of the potential association with the endometriosis risk are needed. The remaining five of the 28 polymorphisms were not associated with endometriosis: glutathione S-transferase theta 1 (GSTT1) null genotype, vascular endothelial growth factor alpha (VEGFA) rs699947, rs833061, rs2010963 and rs3025039.

WIDER IMPLICATIONS

By carefully taking account of how the control populations were defined, we identified polymorphisms that might be candidates for use in endometriosis screening and polymorphisms not associated with endometriosis. This might constitute the first step towards identifying polymorphism combinations that predispose to endometriosis (IFNG (CA) repeat, GSTM1 null genotype, GSTP1 rs1695, WNT4 rs16826658 and WNT4 rs2235529) in a large cohort of patients with well-defined inclusion criteria. In turn, these results might improve the diagnosis of endometriosis in primary care. Lastly, our present findings may enable a better understanding of endometriosis and improve the management of patients with this disease.

Case-control study to develop and validate a questionnaire for the secondary prevention of endometriosis

Background

Endometriosis is a debilitating gynecologic disease characterized by the implantation of endometrial tissue in ectopic locations, with signs of severe and chronic inflammation. The new knowledge on endometriosis has highlighted the value of secondary prevention through the early diagnosis and treatment of lesions to reduce serious consequences, first of all, infertility and chronic pelvic pain. The purpose of this study is to assess the reliability and validity of the questionnaire, as a tool to precociously identify women with endometriosis, to prevent the progression of symptoms.

Method

We reviewed the literature and selected risk factors, symptoms, and phenotypic traits of the women affected by endometriosis to create the questionnaire divided into 8 modules, with 47 questions. A total of 151 women completed the questionnaires: 51 patients who have endometriosis (the cases) and 100 matched women without endometriosis (the controls). After data collection, bivariate and multivariate analyses were conducted.

Results

We retained four of the significant variables from a step-down logistic regression, namely chronic pelvic pain, dyspareunia with VAS≥3, painful defecation, and acne, to develop a final “predictive” logistic model achieving 90.2% sensitivity and 75% specificity.

Conclusion

Our pilot study demonstrated that the questionnaire provides a powerful tool for the secondary prevention of endometriosis.

A detailed profile of pain in severe endometriosis

Objective:

To investigate the detailed nature of pain symptoms reported by women with endometriosis and those without current gynecological complaint.

Design:

Self-administered cross-sectional study was conducted using a structured questionnaire.

Setting:

Teaching hospital clinic, specialist gynecologist, and family practice patients; endometriosis community support group members; and university staff and students.

Subjects:

A total of 737 women returned completed surveys: women with endometriosis ( n = 529) and with no current gynecological complaint ( n = 208).

Intervention(s):

None.

Main outcome measure(s):

Demographics, experience of pain symptoms: frequency, severity, and characteristics.

Results:

All pain symptoms were significantly more common among women with endometriosis compared with controls. Women with endometriosis all reported experiencing dysmenorrhea to some degree ( N = 527, two missing), although the severity was “slight” for 5%. Dyspareunia was reported by 92% of women with endometriosis, most commonly during intercourse, rather than at the start or post-coital. The other pain symptoms experienced by women with endometriosis, in order of frequency, were lower back pain (93%), pain at ovulation (87%), pelvic pain other than during menses, ovulation, urination or intercourse (79%), dysuria (71%), and rectal pain (67%). The great majority of women with endometriosis reported multiple sources and types of pain. Among women with endometriosis there were clear associations between the severity of dysmenorrhea and the frequency of experiencing dyspareunia and other pain symptoms.

Conclusion:

Pain symptoms in women with endometriosis were generally much more extensive and complex than recognized by most clinicians.
