Background/objective:Guidelines support clopidogrel therapy in medically-treated or percutaneous coronary intervention (PCI) patients after hospitalization for acute coronary syndrome (ACS). However, clopidogrel discontinuation has been associated with increased short-term risks. This study evaluated the risk of adverse outcomes (AOs), defined as death or recurrent ACS, after clopidogrel discontinuation in a managed-care population.Methods:ACS patients (n  =  7625) with ≥1 clopidogrel pharmacy claim from 2001 to 2006 and no AO before discontinuing clopidogrel were identified from administrative claims data. AO occurrences were recorded at 90-day intervals following clopidogrel discontinuation.Results:The mean (SD) duration of clopidogrel therapy for medically-treated, bare metal stent (BMS) and drug eluting stent (DES) patients was 349.2 (393.1) days, 235.6 (383.0) days, and 280.2 (227.1) days, respectively. Among medically-treated patients, Poisson regression analysis showed a 2.19 times higher AO risk (p  90 days of treatment. [ABSTRACT FROM AUTHOR]

Background: Routine primary care data may be a valuable resource for preconception health research and to inform the provision of preconception care., Aim: To review how primary care data could provide information on the prevalence of preconception indicators and examine associations with maternal and offspring health outcomes., Design and Setting: Systematic review of observational studies using UK routine primary care data., Method: Literature searches were conducted in March 2023 using five databases to identify observational studies that used national primary care data from individuals aged 15-49 years. Preconception indicators were defined as medical, behavioural, and social factors that may impact future pregnancies; health outcomes included those that may occur during and after pregnancy., Results: From 5259 screened records, 42 articles were included. The prevalence of 37 preconception indicator measures was described for female patients, ranging from 0.01% for sickle cell disease to >20% for each of advanced maternal age, previous caesarean section (among those with a recorded pregnancy), overweight, obesity, smoking, depression, and anxiety (irrespective of pregnancy). Few studies reported indicators for male patients ( n = 3) or associations with outcomes ( n = 5). Most studies had a low risk of bias, but missing data may limit generalisability of the findings., Conclusion: The findings demonstrated that routinely collected UK primary care data could be used to identify patients' preconception care needs. Linking primary care data with health outcomes collected in other datasets is underutilised, but could help to quantify how optimising preconception health and care could reduce adverse outcomes for mothers and children., (© The Authors.)

Introduction: There is growing scientific and policy recognition that optimising health before a potential pregnancy (preconception health) improves reproductive outcomes and the lifelong health of future children. However, public awareness on this topic is low. We conducted a public consultation to develop language recommendations and identify and prioritise approaches to inform research and improve public awareness of preconception health., Methods: A public consultation was undertaken with people of any gender aged 18-50 years living in the United Kingdom who were not currently expecting a child. Public contributors were recruited through patient and public involvement, community and support groups, an existing cohort study, and an LGBTQ+ charity. An initial round of online group discussions (February/March 2021) explored public contributors' knowledge of preconception health, their recommendations for appropriate language, and ideas about public health approaches. In a subsequent discussion round (May 2021), language recommendations were refined and suggested approaches prioritised. Discussions were summarised based on notes taken by two researchers., Results: Fifty-four people joined the initial discussion round (66% women, 21% men, 13% nonbinary or transgender; 55% aged 18-30 years, 30% 31-40 years, 15% 41-50 years). Of these, 36 people (67%) participated in the subsequent round. Very few had heard the term 'preconception health', understood what it means, or why and for whom it is important. They recommended avoiding unfamiliar terms without further explanation (e.g., preconception health, medical terms), using language that is positive, encouraging and gender-sensitive where possible, and using messages that are specific, nonjudgmental and realistic. The phrases 'health and well-being during the childbearing years', 'health and well-being before pregnancy and parenthood' and 'planning for parenthood' resonated with most public contributors. School-based education, social media campaigns and the National Health Service emerged as priority approaches/settings for raising awareness., Conclusion: This public consultation produced recommendations from a diverse group of people of reproductive age in the United Kingdom to improve language and prioritise approaches that increase public understanding of preconception health in ways that are relevant and appropriate to them. This should begin in schools and will require adaptation of curricula, alongside co-development of public awareness campaigns and guidance for healthcare professionals., Patient or Public Contribution: This public consultation included a diverse group of members of the public. They were not involved in the original design of the project, but following the initial round of online group discussions, they contributed to the interpretation and refinement of the emerging concepts in a subsequent round of group meetings. After the consultation activity, public contributors formed a Public Advisory Group and have subsequently been involved in other studies on the same topic. Two public contributors (E.R. and F.F.) provided critical input in the preparation and revision of this manuscript and are co-authors of the paper., (© 2024 The Author(s).

Introduction: Unplanned pregnancies are associated with increased risks. Despite this, they are currently not routinely detected during antenatal care. This study evaluates the implementation of the London Measure of Unplanned Pregnancy (LMUP) - a validated measure of pregnancy planning - into antenatal care at University College London Hospital, Homerton Hospital, and St Thomas' Hospital, England, 2019-2023., Methods: We conducted a mixed methods evaluation of the pilot. Uptake and acceptability were measured using anonymized data with non-completion of the LMUP as a proxy measure of acceptability overall. We conducted focus groups with midwives, and one-to-one interviews with women, to explore their thoughts of asking, or being asked the LMUP, which we analyzed with a Framework Analysis., Results: Asking the LMUP at antenatal appointments is feasible and acceptable to women and midwives, and the LMUP performed as expected. Advantages of asking the LMUP, highlighted by participants, include providing additional support and personalizing care. Midwives' concerns about judgment were unsubstantiated; women with unplanned pregnancies valued such discussions., Conclusions: These findings support the implementation of the LMUP in routine antenatal care and show how it can provide valuable insights into the circumstances of women's pregnancies. This can be used to help midwives personalize care, and potentially reduce adverse outcomes and subsequent unplanned pregnancy. Integration of the LMUP into the Maternity Services Data Set will establish national data collection of a validated measure of unplanned pregnancy and enable analysis of the prevalence, factors, and implications of unplanned pregnancies across subpopulations and over time to inform implementation., Competing Interests: The authors have each completed and submitted an ICMJE form for Disclosure of Potential Conflicts of Interest.

As the average age of first-time parents continues to rise, there has been a concerted effort by educators, policy makers and several reproductive health groups to improve fertility awareness. This study explored fertility knowledge of lay men and women and healthcare professionals (HCPs) using the same test instrument, providing a new and unique perspective compared with previous studies. Results were obtained from 1082 survey respondents: 347 HCPs, 319 men and 413 women, 105 of whom were trying to conceive (TTC). A total of 35 interviewees were purposively sampled to include 9 HCPs, 13 men and 13 women from the reproductive age range and of varying ethnic and educational backgrounds. Interview data were transcribed and analysed using the framework method. The proportion of HCPs correctly answering the survey knowledge questions was 47.1 (95% CI = 41.7%, 52.5%) compared to 44.4% for women (95% CI = 38.9%, 50.1%); 49.9% (95% CI = 39.0, 59.9%) for women TTC; and 32.5% (95% CI = 27.1%, 37.9%) for men. HCPs were ranked as the most trusted source for seeking fertility information. Overall HCPs did not demonstrate better fertility knowledge than lay participants, with inconsistencies regarding where responsibility lies for providing the right information to patients. HCPs need to improve their knowledge about fertility to help improve patient's fertility awareness.

Background: A longstanding gap in the reproductive health field has been the availability of a screening instrument that can reliably predict a person's likelihood of becoming pregnant. The Desire to Avoid Pregnancy Scale is a new measure; understanding its sensitivity and specificity as a screening tool for pregnancy as well as its predictive ability and how this varies by socio-demographic factors is important to inform its implementation., Methods: This analysis was conducted on a cohort of 994 non-pregnant participants recruited in October 2018 and followed up for one year. The cohort was recruited using social media as well as advertisements in a university, school, abortion clinic and outreach sexual health service. Almost 90% of eligible participants completed follow-up at 12 months; those lost to follow-up were not significantly different on key socio-demographic factors. We used baseline DAP score and a binary variable of whether participants experienced pregnancy during the study to assess the sensitivity, specificity, area under the ROC curve (AUROC) and positive and negative predictive values (PPV and NPV) of the DAP at a range of cut-points. We also examined how the predictive ability of the DAP varied according to socio-demographic factors and by the time frame considered (e.g., pregnancy within 3, 6, 9 and 12 months)., Results: At a cut-point of 2 on the 0-4 range of the DAP scale, the DAP had a sensitivity of 0.78, a specificity of 0.81 and an excellent AUROC of 0.87. In this sample the cumulative incidence of pregnancy was 16% (95%CI 13%, 18%) making the PPV 43% and the NPV 95% at this cut-point. The DAP score was the factor most strongly associated with pregnancy, even after age and number of children were taken into account. The association between baseline DAP score and pregnancy did not differ across time frames., Conclusions: This is the first study to assess the DAP scale as a screening tool and shows that its predictive ability is superior to the limited pre-existing pregnancy prediction tools. Based on our findings, the DAP could be used with a cut-point selected according to the purpose., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Objective: To present the first national-level report card on the state of women's preconception health in England., Design: Cross-sectional population-based study., Setting: Maternity services, England., Population: All pregnant women in England with a first antenatal (booking) appointment recorded in the national Maternity Services Dataset (MSDS) from April 2018 to March 2019 (n = 652 880)., Methods: We analysed the prevalence of 32 preconception indicator measures in the overall population and across socio-demographic subgroups. Ten of these indicators were prioritised for ongoing surveillance based on modifiability, prevalence, data quality and ranking by multidisciplinary UK experts., Results: The three most prevalent indicators were the proportion of the 22.9% of women who smoked 1 year before pregnancy who did not quit smoking before pregnancy (85.0%), those who had not taken folic acid supplementation before pregnancy (72.7%) and previous pregnancy loss (38.9%). Inequalities were observed by age, ethnicity and area-based deprivation level. The ten indicators prioritised were not taking folic acid supplementation before pregnancy, obesity, complex social factors, living in the most deprived areas, smoking around the time of conception, overweight, pre-existing mental health condition, pre-existing physical health condition, previous pregnancy loss and previous obstetric complication., Conclusions: Our findings suggest important opportunities to improve the state of preconception health and reduce socio-demographic inequalities for women in England. In addition to MSDS data, other national data sources that record further and possibly better quality indicators could be explored and linked to build a comprehensive surveillance infrastructure., (© 2023 The Authors.

Study Question: What is the proportion of women who experience natural conception after a livebirth via assisted reproductive technology (ART)?, Summary Answer: Current evidence suggests that natural conception pregnancy may occur in at least one in five women after having a baby via IVF or ICSI., What Is Known Already: It is widely known that some women having babies via ART go on to conceive naturally. This reproductive history is of media interest and often described as 'miracle' pregnancies., Study Design, Size, Duration: A systematic review with meta-analysis was carried out. Ovid Medline, Embase, and PsycINFO were searched until 24 September 2021 for English language, human studies from 1980. Search terms were used for the concepts of natural conception pregnancy, assisted reproduction, and livebirth., Participants/materials, Setting, Methods: The inclusion criterion was studies with an outcome measure of the proportion of women experiencing natural conception pregnancy after an ART livebirth. Quality of studies was assessed using the Critical Appraisal Skills Programme cohort study checklist or AXIS Appraisal tool for cross-sectional studies, and a risk of bias assessment was carried out. No studies were excluded based on quality. Random-effects meta-analyses were adopted to produce a pooled effect estimate of the proportion of natural conception pregnancy after ART livebirth., Main Results and the Role of Chance: A total of 1108 distinct studies were identified, resulting in 54 studies after screening by title and abstract. Eleven studies including 5180 women were selected for this review. The included studies were mostly of moderate quality with a maximum follow-up period ranging from 2 to 15 years. Four studies reported natural conception livebirths which were used as known underestimates of natural conception pregnancies. The pooled estimate for the proportion of women having natural conception pregnancies after ART livebirth was 0.20 (95% CI, 0.17-0.22)., Limitations, Reasons for Caution: The studies varied widely according to methodology, population, cause of subfertility, type and outcome of fertility treatment, and length of follow-up, leading to potential bias relating to confounding, selection bias, and missing data., Wider Implications of the Findings: Current evidence suggests that contrary to widely held views, natural conception pregnancy after ART livebirth is far from rare. National, data-linked studies are needed to provide more accurate estimates of this incidence and analysis of associated factors and trends over time to facilitate tailored counselling of couples considering further ART., Study Funding/competing Interest(s): This work was conducted as part of an academic clinical fellowship awarded to AT by the National Institute for Health Research (NIHR). NIHR has had no input into the study design, data collection, and analysis, nor the writing of this study.

Objective: The physical and mental health of women prior to conception can have a significant impact on pregnancy and child outcomes. Given the rising burden of non-communicable diseases, the aim was to explore the relation between mental health, physical health and health behaviour in women planning a pregnancy., Methods: Cross-sectional analysis of responses from 131 182 women to a preconception health digital education tool, providing data on physical and mental health and health behaviour. Logistic regression was used to explore associations between mental health and physical health variables., Results: Physical health conditions were reported by 13.1% and mental health conditions by 17.8%. There was evidence for an association between self-reported physical and mental health conditions (odds ratio [OR] 2.22, 95% CI 2.14-2.3). Those with a mental health condition were less likely to engage with healthy behaviour at preconception such as folate supplementation (OR 0.89, 95% CI 0.86-0.92) and consumption of the recommended amount of fruit and vegetables (OR 0.77, 95% CI 0.74-0.79). They were more likely to be physically inactive (OR 1.14, 95% CI 1.11-1.18), smoke tobacco (OR 1.72, 95% CI 1.66-1.78) and use illicit substances (OR 2.4, 95% CI 2.25-2.55)., Conclusions: Greater recognition of mental and physical comorbidities is needed and closer integration of physical and mental healthcare in the preconception period, which could support people to optimise their health during this time and improve long-term outcomes., (© 2023 The Authors.

Background: To review the highest level of available evidence, a systematic map identified systematic reviews that evaluated the effectiveness of interventions to improve contraception choice and increase contraception use., Methods: Systematic reviews published since 2000 were identified from searches of nine databases. Data were extracted using a coding tool developed for this systematic map. Methodological quality of included reviews was assessed using AMSTAR 2 criteria., Findings and Conclusion: Fifty systematic reviews reported evaluations of interventions for contraception choice and use addressing three domains (individual, couples, community); Meta-analyses in 11 of the reviews mostly addressed interventions for individuals. We identified 26 reviews covering High Income Countries, 12 reviews covering Low Middle-Income Countries and the rest a mix of both. Most reviews (15) focussed on psychosocial interventions, followed by incentives (6) and m-health interventions (6). The strongest evidence from meta-analyses is for the effectiveness of motivational interviewing, contraceptive counselling, psychosocial interventions, school-based education, and interventions promoting contraceptive access, demand-generation interventions (community and facility based, financial mechanisms and mass media), and mobile phone message interventions. Even in resource constrained settings, community-based interventions can increase contraceptive use. There are gaps in the evidence on interventions for contraception choice and use, and limitations in study designs and lack of representativeness. Most approaches focus on individual women rather than couples or wider socio-cultural influences on contraception and fertility. This review identifies interventions which work to increase contraception choice and use, and these could be implemented in school, healthcare or community settings.
