BACKGROUND Supportive care is regularly offered to women with recurrent miscarriages (RMs). Their preferences for supportive care in their next pregnancy have been identified by qualitative research. The aim of this study was to quantify these supportive care preferences and identify womens characteristics that are associated with a higher or lower need for supportive care in women with RM. METHODS A questionnaire study was conducted in women with RMs (≥ 2 miscarriages) in three hospitals in the Netherlands. All women who received diagnostic work-up for RMs from January 2010 to December 2010 were sent a questionnaire. The questionnaire quantified supportive care options identified by a previous qualitative study. We next analysed associations between womens characteristics (age, ethnicity, education level, parity, pregnancy during questionnaire and time passed since last miscarriage) and their feelings about supportive care options to elucidate any differences between groups. RESULTS Two hundred and sixty-six women were asked to participate in the study. In total, 174 women responded (response rate 65%) and 171 questionnaires were analysed. Women with RM preferred the following supportive care options for their next pregnancy: a plan with one doctor who shows understanding, takes them seriously, has knowledge of their obstetric history, listens to them, gives information about RM, shows empathy, informs on progress and enquires about emotional needs. Also, an ultrasound examination during symptoms, directly after a positive pregnancy test and every 2 weeks. Finally, if a miscarriage occurred, most women would prefer to talk to a medical or psychological professional afterwards. The majority of women expressed a low preference for admission to a hospital ward at the same gestational age as previous miscarriages and for bereavement therapy. The median preference, on a scale from 1 to 10, for supportive care was 8.0. Ethnicity, parity and pregnancy at the time of the survey were associated with different preferences, but female age, education level and time passed since the last miscarriage were not. CONCLUSIONS Women with RM preferred a plan for the first trimester that involved one doctor, ultrasounds and the exercise of soft skills, like showing understanding, listening skills, awareness of obstetrical history and respect towards the patient and their miscarriage, by the health care professionals. In the event of a miscarriage, women prefer aftercare. Women from ethnic minorities and women who were not pregnant during the questionnaire investigation were the two patient groups who preferred the most supportive care options. Tailor-made supportive care can now be offered to women with RM.

BACKGROUND At present, it is unclear which treatment strategy is best for couples with unexplained or mild male subfertility. We hypothesized that the prognostic profile influences the effectiveness of assisted conception. We addressed this issue by analysing individual patient data (IPD) from randomized controlled trials (RCTs). METHODS We performed an IPD analysis of published RCTs on treatment strategies for subfertile couples. Eligible studies were identified from Cochrane systematic reviews and we also searched Medline and EMBASE. The authors of RCTs that compared expectant management (EM), intracervical insemination (ICI), intrauterine insemination (IUI), all three with or without controlled ovarian stimulation (COS) and IVF in couples with unexplained or male subfertility, and had reported live birth or ongoing pregnancy as an outcome measure, were invited to share their data. For each individual patient the chance of natural conception was calculated with a validated prognostic model. We constructed prognosis-by-treatment curves and tested whether there was a significant interaction between treatment and prognosis. RESULTS We acquired data from 8 RCTs, including 2550 couples. In three studies (n = 954) the more invasive treatment strategies tended to be less effective in couples with a high chance of natural conception but this difference did not reach statistical significance (P-value for interaction between prognosis and treatment outcome were 0.71, 0.31 and 0.19). In one study (n = 932 couples) the strategies with COS (ICI and IUI) led to higher pregnancy rates than unstimulated strategies (ICI 8% versus 15%, IUI 13% versus 22%), regardless of prognosis (P-value for interaction in all comparisons >0.5), but at the expense of a high twin rate in the COS strategies (ICI 6% versus 23% and IUI 3% versus 30%, respectively). In two studies (n = 373 couples), the more invasive treatment strategies tended to be more effective in couples with a good prognosis but this difference did not reach statistical significance (P-value for interaction: 0.38 and 0.68). In one study (n = 253 couples) the differential effect of prognosis on treatment effect was limited (P-value for interaction 0.52), perhaps because prognosis was incorporated in the inclusion criteria. The only study that compared EM with IVF included 38 couples, too small for a precise estimate. CONCLUSIONS In this IPD analysis of couples with unexplained or male subfertility, we did not find a large differential effect of prognosis on the effectiveness of fertility treatment with IUI, COS or IVF.

In couples with unexplained infertility, no convincing evidence is available that treatment with intra uterine insemination (IUI) with or without ovarian stimulation (OS) or in vitro fertilisation (IVF) improves pregnancy rates compared to expectant management. Expectant management in couples with unexplained infertility leads to live birth rates varying between 10 and 50 % per year, depending on their prognosis, based on female age, duration of subfertility and the outcomes of the fertility workup. Optimal implementation of expectant management in couples with good prospects of natural conception can prevent unnecessary treatments, complications and costs.
