The impact of the COVID-19 pandemic on infertility patients and endometriosis patients in the Netherlands.

RESEARCH QUESTION: How do infertility patients, endometriosis patients and health-care providers rate virtual care as an alternative to physical consultations during the first lockdown of the coronavirus disease 2019 (COVID-19) pandemic in the Netherlands, and how does this influence quality of life and quality of care? DESIGN: Infertility patients and endometriosis patients from a university hospital and members of national patient organizations, as well as healthcare providers in infertility and endometriosis care, were asked to participate between May and October 2020. The distributed online questionnaires consisted of an appraisal of virtual care and an assessment of fertility-related quality of life (FertiQol) and patient-centredness of endometriosis care (ENDOCARE). RESULTS: Questionnaires were returned by 330 infertility patients, 181 endometriosis patients and 101 healthcare providers. Of these, 75.9% of infertility patients, 64.8% of endometriosis patients and 80% of healthcare providers rated telephone consultations as a good alternative to physical consultations during the COVID-19-pandemic. Only 21.3%, 14.8% and 19.2% of the three groups rated telephone consultations as a good replacement for physical consultations in the future. A total of 76.6% and 35.9% of the infertility and endometriosis patients reported increased levels of stress during the pandemic. Infertility patients scored lower on the FertiQol, while the ENDOCARE results care seem comparable to the reference population. CONCLUSIONS: Virtual care seems to be a good alternative for infertility and endometriosis patients in circumstances where physical consultations are not possible. Self-reported stress is especially high in infertility patients during the COVID-19-pandemic. Healthcare providers should aim to improve their patients' ability to cope.

Safety of oil-based contrast medium for hysterosalpingography: a systematic review.

Recent meta-analyses have shown that a hysterosalpingography (HSG) with oil-based contrast increases pregnancy rates in subfertile women. However, the frequency of complications during or after an HSG with oil-based contrast in subfertile women and/or their offspring is still unclear. This systematic review and meta-analysis, without restrictions on language, publication date or study design, was performed to fill this knowledge gap. The results show that the most frequently reported complication was intravasation of contrast, which occurred in 2.7% with the use of oil-based contrast (31 cohort studies and randomized controlled trials [RCT], 95% CI 1.7-3.8, absolute event rate 664/19,339), compared with 2.0% with the use of water-based contrast (8 cohort studies and RCT, 95% CI 1.2-3.0, absolute event rate 18/1006). In the cohort studies and RCT there were 18 women with an oil embolism (18/19,339 HSG), all without serious lasting consequences. Four cases with serious consequences of an oil embolism were described (retinal oil embolism [n = 1] and cerebral complaints [n = 3]); these reports did not describe the use of adequate fluoroscopy guidance during HSG. In conclusion, the most frequently reported complication after an HSG with oil-based contrast is intravasation occurring in 2.7%. In total four cases with serious consequences of oil embolisms in subfertile women were published.

How long does the fertility-enhancing effect of hysterosalpingography with oil-based contrast last?

RESEARCH QUESTION: Does the fertility-enhancing effect of tubal flushing during hysterosalpingography (HSG) with oil-based contrast change over time? DESIGN: This was a secondary analysis of the H2Oil (long-term follow-up) study, a multicentre randomized controlled trial evaluating the effectiveness of oil-based and water-based contrast during HSG. The main outcome was ongoing pregnancy. Cox proportional hazards models for time to ongoing pregnancy were fitted over 3 years of follow-up. RESULTS: Data on 1107 couples were available; 550 couples had oil-based contrast and 557 water-based contrast at HSG. Ongoing pregnancy rates after 3 years were 77% and 71%, respectively. Median follow-up was 9-10 months (5th-95th percentile: <1 to 36). The hazard ratio for ongoing pregnancy for oil versus water over 3 years of follow-up was 1.26 (95% confidence interval [CI] 1.10-1.45). The scaled Schoenfeld residual plots showed a decrease in hazard ratio that was linear with log-transformed time. After including an interaction with log-transformed time, the hazard ratio immediately after HSG was 1.71 (95% CI 1.27-2.31) and reduced to no effect (hazard ratio of 1) at approximately 2 years. There was no evidence for a change in hazard ratio over time in a subgroup of women who experienced pain during HSG. CONCLUSIONS: The hazard ratio for ongoing pregnancy of oil-based versus water-based contrast was 1.71 immediately after HSG, gradually decreasing and plateauing towards a hazard ratio of 1 (indicating no effect) after approximately 2 years. This supports the hypothesis that oil-based contrast might dislodge debris or mucus plugs from the Fallopian tubes, but this has yet to be definitively proved.
