Silver","doi":"10.1111/1471-0528.17920","DOIUrl":"10.1111/1471-0528.17920","url":null,"abstract":"<p>One of the most concerning papers in this issue of BJOG is a study from the Netherlands noting an increased percentage of maternal deaths (through one year postpartum) are due to suicide (Lommerse et al, BJOG 2024). The percentage of maternal deaths in the Netherlands due to suicide increased from 18% between 1996 to 2005, to 28% between 20006 to 2020. Indeed, suicide is now the leading cause of maternal death in the Netherlands. Sadly, this problem is not unique to Holland. Suicide is also the most common cause of maternal death in the U.K., France, and the U.S. (Diguisto et al, BMJ. 2022;379:e070621; Knight et al., Oxford: National</p><p>Perinatal Epidemiology Unit, University of Oxford; 2021; Khalifeh et al, Lancet Psychiatry. 2016; 3:233–42; Trost et al, Centers for Disease Control and Prevention, U.S. Department of Health and Human Services; 2024). Further, mortality is merely the tip of the iceberg, accounting for only a small fraction of cases of severe maternal mental health and substance use disorders. Accordingly, improved screening for and treatment of mental health conditions and substance use disorder has the potential to greatly impact maternal morbidity and mortality.</p><p>A theme linking several articles in this issue of BJOG, are the “non-scientific” aspects of medicine. These include implementation science, patient experience, and cost-effectiveness. Moffat and coworkers report on postpartum contraception uptake in the Northeast and North Cumbrian Integrated Care System in England (Moffat et al; BJOG 2024). Data were obtained via online survey, and thus, prone to bias. Nonetheless, only 38.7% of respondents accessed any contraception postpartum, and only 15.5% accessed long-acting reversable contraception. 18.8 % indicated that they could not obtain their preferred method of contraception. These data underscore the need for better implementation strategies. Although we know that contraception is effective, it only works if people can obtain it. Further work should identify barriers (educational, logistical, financial, cultural, etc.) and potential solutions to enhance utilization of contraception and other effective interventions.</p><p>The emotional impact of medical interventions is critically important, but often neglected in research studies. In work by Kwong et al, 2596 people evaluated for ovarian cancer were evaluated for anxiety using the State-trait anxiety inventory (STAI-6) and distress using the Impact of Event Scale – revised (Kwong et al, BJOG 2024). 52.1% of participants reported moderate-severe anxiety and 68.6% had moderate-severe distress. Category of anxiety or distress remained unchanged or worse after 12 months in 76%, despite finding out that they did not have cancer. This study underscores the need to provide mental health support for people being evaluated for cancer, and to consider the duress associated with false positive screening tests.
