Quality of life and clinical factors in women with endometriosis, the role of dienogest vs EE/dienogest over time: a single-center study

Measurement properties of sexual function assessment questionnaires in women with endometriosis: A systematic review following COSMIN guidelines

INTRODUCTION

Sexual function of patients with endometriosis should be assessed by patient-reported outcome measures (PROMs) that present high reliability and validity. The objective was to study the PROMs used to assess sexual function for patients with endometriosis to improve their selection for research and clinical practice.

MATERIAL AND METHODS

We performed a systematic literature review from January 2000 to September 2023. All studies including women with confirmed endometriosis and assessing sexual quality of life or sexual function or sexual distress were retrieved. Different properties of PROMs used for sexual dysfunction were assessed according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) recommendations. Properties evaluated were: structural validity, internal consistency, cross-cultural validity, reliability, measurement error, criterion validity, construct validity, and responsiveness. This literature review was registered on Prospero as 2018 CRD42018102278.

RESULTS

Seventy-four articles with evaluation of sexual function were included. Of the 25 PROMs assessing sexual function, the Female Sexual Function Index (FSFI) was the most frequently used (34/74 [45.9%] items), followed by the Female Sexual Distress Scale (9/74 [12.2%] items) and the Sexual Activity Questionnaire (SAQ) (8/74 [10.8%] items). The most commonly used measurement properties were "hypothesis testing" and "responsiveness". The PROMs with a high level of evidence for these two measurement properties were the FSFI, the SAQ, the Short Sexual Functioning Scale, the Sexual Satisfaction Scale for Women, Sexual Quality of Life-Female, the Brief Profile of Female Sexual Function, and the Sexual Health Outcomes in Women Questionnaire. The FSFI questionnaire appeared to be more relevant for evaluating medical treatment, and the SAQ for evaluating surgical treatment. Only one instrument was specific to endometriosis (the Subjective Impact of Dyspareunia Inventory [SIDI]).

CONCLUSIONS

In this systematic literature review of sexual function assessment questionnaires in endometriosis, the FSFI and the SAQ questionnaires emerged as having the best measurement properties according to the COSMIN criteria. The FSFI questionnaire appears to be suited for evaluating medical treatment, and the SAQ for surgical treatment. The SIDI is the only specific questionnaire, but its responsiveness remains to be defined.

The Perception of the Quality of Professional Healthcare Assistance for the Management of Endometriosis: Findings from a National Survey in Italy

(1) Background: endometriosis is included in the list of chronic and disabling pathologies. This study aimed to examine patients' points of view about the quality of care for endometriosis during the COVID-19 pandemic; (2) Methods: we conducted a survey on knowledge about endometriosis, management of endometriosis, perceived mental and physical well-being, and perceived changes in the quality of care during the pandemic; (3) Results: out of 1065 participants, 875 were included in the analysis, with an average age of 34. Overall, patients had positive perceptions of care accessibility and cleanliness (95%), but less satisfaction with visit hours (86%). Those with better physical and psychological health were more satisfied with service hours, while those treated at specialised centres were more content with cleanliness. Satisfaction with clarity was linked to specialist treatment, and perceived availability to listen correlated with age, complications, and overall health status; (4) Conclusions: patients' perspectives are crucial for patient education and advocate for specialised interdisciplinary networks to support endometriosis management and patients' well-being. These findings highlight the importance of considering patient viewpoints, particularly in the context of the COVID-19 pandemic's impact on healthcare systems and suggest a need for further research from the patient's perspective.
