RESUMEN
STUDY QUESTION: Is a single endometrial scratch prior to the second fresh IVF/ICSI treatment cost-effective compared to no scratch, when evaluated over a 12-month follow-up period? SUMMARY ANSWER: The incremental cost-effectiveness ratio (ICER) for an endometrial scratch was 6524 per additional live birth, but due to uncertainty regarding the increase in live birth rate this has to be interpreted with caution. WHAT IS KNOWN ALREADY: Endometrial scratching is thought to improve the chances of success in couples with previously failed embryo implantation in IVF/ICSI treatment. It has been widely implemented in daily practice, despite the lack of conclusive evidence of its effectiveness and without investigating whether scratching allows for a cost-effective method to reduce the number of IVF/ICSI cycles needed to achieve a live birth. STUDY DESIGN, SIZE, DURATION: This economic evaluation is based on a multicentre randomized controlled trial carried out in the Netherlands (SCRaTCH trial) that compared a single scratch prior to the second IVF/ICSI treatment with no scratch in couples with a failed full first IVF/ICSI cycle. Follow-up was 12 months after randomization.Economic evaluation was performed from a healthcare and societal perspective by taking both direct medical costs and lost productivity costs into account. It was performed for the primary outcome of biochemical pregnancy leading to live birth after 12 months of follow-up as well as the secondary outcome of live birth after the second fresh IVF/ICSI treatment (i.e. the first after randomization). To allow for worldwide interpretation of the data, cost level scenario analysis and sensitivity analysis was performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: From January 2016 until July 2018, 933 women with a failed first IVF/ICSI cycle were included in the trial. Data on treatment and pregnancy were recorded up until 12 months after randomization, and the resulting live birth outcomes (even if after 12 months) were also recorded.Total costs were calculated for the second fresh IVF/ICSI treatment and for the full 12 month period for each participant. We included costs of all treatments, medication, complications and lost productivity costs. Cost-effectiveness analysis was carried out by calculating ICERs for scratch compared to control. Bootstrap resampling was used to estimate the uncertainty around cost and effect differences and ICERs. In the sensitivity and scenario analyses, various unit costs for a single scratch were introduced, amongst them, unit costs as they apply for the United Kingdom (UK). MAIN RESULTS AND THE ROLE OF CHANCE: More live births occurred in the scratch group, but this also came with increased costs over a 12-month period. The estimated chance of a live birth after 12 months of follow-up was 44.1% in the scratch group compared to 39.3% in the control group (risk difference 4.8%, 95% CI -1.6% to +11.2%). The mean costs were on average 283 (95% CI: -299 to 810) higher in the scratch group so that the point average ICER was 5846 per additional live birth. The ICER estimate was surrounded with a high level of uncertainty, as indicated by the fact that the cost-effectiveness acceptability curve (CEAC) showed that there is an 80% chance that endometrial scratching is cost-effective if society is willing to pay â¼17â500 for each additional live birth. LIMITATIONS, REASONS FOR CAUTION: There was a high uncertainty surrounding the effects, mainly in the clinical effect, i.e. the difference in the chance of live birth, which meant that a single straightforward conclusion could not be ascertained as for now. WIDER IMPLICATIONS OF THE FINDINGS: This is the first formal cost-effectiveness analysis of endometrial scratching in women undergoing IVF/ICSI treatment. The results presented in this manuscript cannot provide a clear-cut expenditure for one additional birth, but they do allow for estimating costs per additional live birth in different scenarios once the clinical effectiveness of scratching is known. As the SCRaTCH trial was the only trial with a follow-up of 12 months, it allows for the most complete estimation of costs to date.

RESEARCH QUESTION: To evaluate implementation of the key recommendations of the European Society of Human Reproduction and Embryology (ESHRE) guidelines on endometriosis, and to assess factors influencing diagnostic delay of endometriosis from Dutch gynaecologists' point of view. DESIGN: Questionnaire study among gynaecologists from all hospitals in the Netherlands. The questionnaire consisted of 56 questions relating to implementation of the ESHRE guidelines, organization of endometriosis care and diagnostic delay. RESULTS: Gynaecologists from 67 out of 85 hospitals completed the questionnaire. A total of 99-100% of respondents agree with, and 91-100% adhere to, the diagnosis-related recommendations in the guidelines. Diagnostic delay is estimated at 42 months. Main factors contributing to diagnostic delay according to gynaecologists are lack of knowledge and awareness of endometriosis in both patients and medical professionals, as well as limitations in diagnostics and late referral. Suggested interventions to reduce diagnostic delay are aimed at improving knowledge and awareness in both patients and medical professionals, as well as improving collaborations between medical professionals. CONCLUSIONS: Overall familiarity with, and use of, the 2014 ESHRE guidelines among Dutch gynaecologists is high. Dutch gynaecologists agree with the recommendations relating to diagnosis and adhere to them closely. Diagnostic delay, however, is still considerable; therefore, efforts to reduce diagnostic delay of endometriosis should be aimed at improving knowledge and awareness in both patients and medical professionals, as well as improving collaboration.

BACKGROUND/AIMS: Endometriosis has a long diagnostic delay that is influenced by varying socio-economic and healthcare factors. In the Dutch situation, these factors are not yet identified. The aim of this study is to determine the length of the diagnostic delay of endometriosis in the Netherlands and to identify which variables affect this delay. METHODS: A retrospective study among 139 patients diagnosed with endometriosis in a secondary care hospital with a specialized multidisciplinary endometriosis team. The diagnostic process was evaluated using a questionnaire-guided telephonic interview. RESULTS: The median time interval from the onset of symptoms to diagnosis was 89 months or 7.4 years, divided in 7 months patient delay, 35 months general practitioner (GP) delay and 5 months gynecologist delay. Determinants for a longer diagnostic delay were young age at onset of symptoms, use of oral contraceptives or analgesics prescribed by GP, alternative diagnoses considered by the GP, and cyclic symptoms. Subfertility as presenting symptom resulted in faster diagnosis. CONCLUSION: This study shows that the time interval to the diagnosis of endometriosis is long and mainly consists of the period of time the woman consults her first line medical professional.

This study aimed to investigate the influence of hormonal treatment on the vaginal microbiome during fertility treatments. Bacterial vaginosis (BV) could affect fecundity, particularly in the in vitro fertilization (IVF) population, where negative effects on pregnancy outcomes have been reported. It is hypothesized that the hormone treatment during fertility treatments could influence the abundance of Lactobacilli, with negative effects on the pregnancy results. A total of 53 couples attending a fertility clinic in the Netherlands between July 2019 and August 2022 were included in this prospective cohort study. Vaginal samples were collected at start of treatment, oocyte retrieval or insemination from subjects undergoing intra uterine insemination (IUI) with mild ovarian stimulation, and IVF or intra cytoplasmatic sperm injection (ICSI) with controlled ovarian hyperstimulation. AmpliSens® Florocenosis/Bacterial vaginosis-FRT qPCR and 16S rRNA gene-based amplicon sequencing were performed on all samples. In total, 140 swabs were analyzed, with a median of two swabs per person. 33 (24%) tested qPCR BV positive. Lactobacilli percentage decreased during fertility treatments, leading to changes in the vaginal microbiome. Shannon diversity index was not significantly different. Of the total of 53 persons, nine switched from qPCR BV negative to positive during treatment. The persons switching to qPCR BV positive had already a (not significant) higher Shannon diversity index at start of treatment. If the vaginal microbiome of persons deteriorates during fertility treatments, timing of following treatments, lifestyle modifications, or a freeze all strategy could be of possible benefit.

OBJECTIVE: Hormone replacement therapy is the most effective treatment for postmenopausal flushing. Unfortunately, its use is often contraindicated. A limited amount of uncontrolled data suggests that stellate-ganglion block (SGB) may be useful for the treatment of hot flushes. In the present study, we examined whether previously reported results could be reproduced in women with severe postmenopausal flushing. METHODS: Twenty postmenopausal women with a baseline hot flush score ≥ 15 were treated with SGB in an open, uncontrolled setting. This mean daily hot flush score was calculated as the product of flush frequency and flush severity over a period of 1 week. The response to treatment was evaluated by flush scores and assessment of quality of life at baseline and 4 weeks after SGB. RESULTS: The per-protocol analysis included 19 women. One woman was excluded because of lack of Horner syndrome after SGB. Four weeks after SGB, the mean flush score had decreased by 34 ± 7.4% (95% confidence interval (CI) 18-49%; p < 0.005). Nine women had a decrease in flush score between 40 and 90%, with a mean response of 65 ± 4.9% (95% CI 53-76%). The other ten women were non-responders with a decrease in flush score between 0 and 11%. Quality of life and sleep, both assessed by questionnaire, improved significantly. CONCLUSIONS: The results of this study support the observation that SGB may be a useful therapy for a subset of women with severe postmenopausal flushing. A sham-controlled, single-blinded study is warranted to improve the evidence of efficacy.
