Nonetheless, the European Union has set up a vigilance system to monitor these complications. However, this system is not an exhaustive source of information and does not provide a complete overview of post-ART complications.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>STUDY DESIGN, SIZE, DURATION<\/jats:title>\n                  <jats:p>The study population was identified from the comprehensive French national hospital discharge database. It included women under 46\u2009years of age undergoing an oocyte retrieval in 2019, classified into three population subgroups according to the indication of oocyte retrieval: infertility (IF) , fertility preservation (FP), and oocyte donation (OD) . The study population included 52\u200a098 women who had undergone 65\u200a948 oocyte retrievals in 2019.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>PARTICIPANTS\/MATERIALS, SETTING, METHODS<\/jats:title>\n                  <jats:p>Hospital stays and delivery of antibiotics within 31\u2009days after oocyte retrieval were analyzed. Women and infections were characterized according to various characteristics (age, comorbidities, indication of oocyte retrieval, type of hospital stay, length of hospital stay, type of antibiotherapy, etc.). Multivariate analysis was performed to determine the relation between the occurrence of infection and women\u2019s characteristics, and results are expressed as odds ratios (ORs) and 95% CI. A funnel plot and a box plot were used to compare the infection rate per center with the national average and to detect outliers.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>MAIN RESULTS AND THE ROLE OF CHANCE<\/jats:title>\n                  <jats:p>Infections in the month following the oocyte retrieval represented 6.9% of the procedures in 2019 (n\u2009=\u20094522). Of these infections, 112 were hospitalized (0.2% of oocyte retrievals), and 4410 were non-hospitalized (6.7% of oocyte retrievals). The hospitalized infections were essentially gynecological infections (40.9%) and urinary tract infections (23.5%). In 87.9% of non-hospitalized infections, a single antibiotic therapy was prescribed. Mixed-effect model analysis showed that the risk of infection was significantly higher in women under 30\u2009years of age, in the FP population, in supplementary universal health coverage (CMU-C) beneficiaries, and women with endometriosis. Funnel plot and box plot analysis showed that three ART centers have an infection rate significantly higher than the national average. In the three centers that stand out from all the others, the objective is to return to these centers to understand the possible reasons for this observed rate and to implement corrective measures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>LIMITATIONS, REASONS FOR CAUTION<\/jats:title>\n                  <jats:p>Despite all its advantages, the French national health data system presents some limitations, such as the risk of inappropriate coding. Another limitation of this study is that we cannot confirm an attributable relation between the infection and the ART procedure, even if the delay of 31\u2009days after oocyte retrieval is consistent with the occurrence of a post-retrieval complication. In addition, antibiotics may be prescribed as a \u2018precautionary\u2019 measure in certain situations (women with a susceptibility to infection, complicated procedures), or as antibiotic prophylaxis for embryo transfer.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>WIDER IMPLICATIONS OF THE FINDINGS<\/jats:title>\n                  <jats:p>Despite the limits in identifying post-ART infections in medico-administrative databases, this approach is a promising way to complement the ART vigilance reporting system. This concept developed for infections will also be generalized to other complications with regular feedback to professionals.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>STUDY FUNDING\/COMPETING INTEREST(S)<\/jats:title>\n                  <jats:p>No specific funding was sought for the study.
