Brief summary

The ENDALGOFIV study of pain assessment during the IVF pathway at Lille University Hospital, conducted from November 2018 to July 2020, showed that endometriosis patients have intense pain, particularly of a neuropathic nature, even before starting their IVF pathway compared to patients without endometriosis, but without an increase in pain scores during the IVF pathway. As a result of this study, a new pain management protocol for all patients undergoing IVF have been implemented in our MPA center. The study will be evaluated the impact of this new management. Main objective To evaluate the effect of the change in pain management protocol in all patients (endometriotic or not) undergoing IVF treatment during the study period by comparing them to the data of the ENDALGOFIV 1 study.

Interventions

Survey will be at different time of the IVF protocol (at the first medical appointment in the medically assisted department, after stimulation, after oocytes retrieval, after embryo transfer, one month after the IVF protocol)

Design outcomes

Primary

MeasureTime frameDescription
Questionnaire douleur Saint Antoine (QDSA)After puncture, before discharge from hospital (assessed up to 24 hours)QDSA for emotional and sensory dimension of pain. It's a word list to describe a pain, patient must specify the type of pain that she usually feels for 8 days by putting a cross for the correct answer (0 to 4: absent, weak, moderate, strong, extremely strong). Scored from 0 to 64

Secondary

MeasureTime frameDescription
EN = numerical scale of painAt baseline and during procedure ( an average up to 6 weeks)from 0 to 10 (0 is no pain and 10 is maximum pain imaginable) compare the evolution of pain during study between the 2 groups endometriosis - non endometriosis
DN4At baseline and during procedure ( an average up to 6 weeks)emotional and sensory dimension of pain, neuropathic pain survey in four questions - score on 7 compare the evolution of pain during study between the 2 groups endometriosis - non endometriosis
HAD,anxiety and depressionAt baseline and during procedure ( an average up to 6 weeks)2 scores on 21 - circle the number that best fits your condition Compare the evolution of pain during study according to the 2 periods (ENDALGOFIV 1 patients and patients who benefited from the new management protocol)
EQ-5D quality of lifeAt baseline and during procedure ( an average up to 6 weeks)overall score on a numeric scale check the box that best describes your health today, 5 themes (mobility, autonomy of the person, common activities, pain / discomfort, anxiety / depression) Compare the evolution of pain during study according to the 2 periods (ENDALGOFIV 1 patients and patients who benefited from the new management protocol)
Questionnaire douleur Saint Antoine (QDSA)At baseline and during procedure ( an average up to 6 weeks)compare the evolution of pain during study between the 2 groups endometriosis - non endometriosis
willingness to go the pain consultation: yes or no answerduring the stimulation period (an average 10 days)measure the impact of the pain on the pregnancy project and on the analgesic management after stimulation between the 2 endometriosis - non-endometriosis groups
willingness to take a antalgic medication during the stimulation: yes or no answerduring the stimulation period (an average 10 days)measure the impact of the pain on the pregnancy project and on the analgesic management after stimulation between the 2 endometriosis - non-endometriosis groups
willingness to take a antalgic medication during the punction: yes or no answerduring the stimulation period (an average 10 days)measure the impact of the pain on the pregnancy project and on the analgesic management after stimulation between the 2 endometriosis - non-endometriosis groups
pain catastrophism scale (PCS)At baseline and during procedure ( an average up to 6 weeks)score between 0 to 52. Compare the evolution of pain during study according to the 2 periods (ENDALGOFIV 1 patients and patients who benefited from the new management protocol)
