BACKGROUND

The impact of fibroids, not encroaching the endometrial cavity, have on the rate of success of IVF is still controversial. Recent meta-analyses suggest a detrimental effect of intramural lesions but not subserosal lesions. However, they also emphasize the need for further evidence. In order to elucidate this, we designed a prospective cohort study to compare the rate of success of IVF in women with and without fibroids.

METHODS

Exposed women were those with asymptomatic intramural or subserosal fibroids with a diameter below 50 mm and who were selected for IVF. Unexposed women were those free of fibroids, who were matched to cases by age and number of previous IVF cycles. All recruited patients underwent hystero-sonography to rule out intra-cavitary lesions.

RESULTS

There were 119 cases and 119 controls recruited. The number of clinical pregnancies in women with and without fibroids was 28 (24%) and 22 (19%), respectively (P= 0.43). The adjusted odds ratio (OR) for pregnancy in affected women was 1.38 [95% confidence interval (CI): 0.73–2.60]. The number of deliveries was 22 (18%) and 16 (13%), respectively (P= 0.38). The adjusted OR was 1.45 (95% CI: 0.71–2.94). Similar results emerged when focusing exclusively on women carrying intramural lesions (n= 80 couples). There was no significant relationship between clinical outcome and either the number or size of the fibroids.

CONCLUSIONS

In asymptomatic patients selected for IVF, small fibroids not encroaching the endometrial cavity did not impact on the rate of success of the procedure.

BACKGROUND

High-quality care for patients faced with infertility should be patient-centred. Few studies have provided in-depth insights into the patient's perspective on care and, to the best of our knowledge, no study has provided a model of the complex concept ‘patient-centred infertility care’. Therefore, a qualitative study aimed at understanding ‘patient-centred infertility care’ from the patient's perspective was conducted.

METHODS

Fourteen focus group discussions were organized with patients (n = 103) from two European countries to find out about patients’ positive and negative experiences with infertility care. Content analysis of the transcripts and analysis of patients’ priority lists were conducted.

RESULTS

The patient-centredness of infertility care depends on 10 detailed dimensions, which can be divided into system and human factors, and there is a two-way interaction between both kinds of factors. System factors, in order of patient's priority, are: provision of information, competence of clinic and staff, coordination and integration, accessibility, continuity and transition and physical comfort. Human factors, in order of patient’s priority, are: attitude of and relationship with staff, communication, patient involvement and privacy and emotional support.

CONCLUSIONS

This study provides a detailed patient's description of the concept ‘patient-centred infertility care’ and an interaction model that aids understanding of the concept. Fertility clinics are encouraged to improve the patient-centredness of their care by taking into account the detailed description of the dimensions of patient-centred infertility care, and by paying attention to both system and human factors and their interaction when setting up ‘patient-centred improvement projects’.

BACKGROUND

Proper use of clinical practice guidelines can decrease variation in care between settings. However, actual use of fertility guidelines is suboptimal and in need of improvement. Hence, a cluster-randomized controlled trial was designed to study the effects of two strategies to implement national Dutch guidelines on comprehensive fertility care.

METHODS

Sixteen fertility clinics participated in the trial. A minimal, professional-oriented implementation strategy of audit and feedback was tested versus a maximal multi-faceted strategy that was both professional and patient oriented. The extent of adherence to guideline recommendations, reflected in quality indicator scores, was the primary outcome measure. To gain an insight into unwanted side effects, patient anxiety and depression scores were gathered as secondary outcomes. Data collection encompassed medical record search, patient and professional questionnaires.

RESULTS

A total of 1499 couples were included at baseline and 1396 at the after-measurement. No overall significant improvement in indicator scores was found for either strategy [odds ratios ranging from 0.23 (95% confidence interval (CI): 0.06–0.95) to 6.66 (95% CI: 0.33–132.8]. Secondary outcomes did not differ significantly for both groups, although selected anxiety scores appeared lower in the maximal intervention group. Process evaluation of the trial revealed positive patient experiences with the intervention material [e.g. an increased understanding of their doctor's treatment policy (61%), an increased ability to ask questions about the treatment (61%)]. Professionals’ appreciation of intervention elements varied, and execution of the multi-faceted strategy appeared incomplete.

DISCUSSION

Absence of an intervention effect may be due to the nature of the strategies, incomplete execution or flaws in study design. Process evaluation data raise the question of whether professionals should be the only stakeholder responsible for guideline implementation. This study therefore contributes to an increased understanding of fertility guideline implementation in general, and the role of patients in particular.

BACKGROUND

The aim of this study was to define determinants of fertility in patients treated conservatively for mucinous borderline ovarian tumours (MBOTs), and to compare outcomes after salpingo-oophorectomy or cystectomy.

METHODS

This was a retrospective cohort study of fertility results in a series of patients treated conservatively for MBOTs and desiring pregnancy. Conservative surgery was defined as preservation of the uterus and ovarian tissue in one or both adnexa(e). Fertility results were compared with patients who had undergone a cystectomy or a (salpingo-)oophorectomy. Only patients with a minimum of 1 year of follow-up were included. Epidemiological, surgical, histological parameters and other prognostic factors for fertility results were investigated.

RESULTS

A group of 31 patients who had been treated conservatively between 1997 and 2004 and who desired pregnancy were investigated. Patients were treated by unilateral salpingo-oophorectomy (USO) (n = 19) or cystectomy (n = 12). The 5-year recurrence-free survival rate was higher in the USO group compared with the cystectomy group (94.7 versus 49.1%, P = 0.041). Among the 31 women, 12 had become pregnant. The 5-year probabilities of pregnancy were comparable between the cystectomy and salpingo-oophorectomy groups (41.8 and 45.9%, respectively, P= 0.66). None of the other factors studied (epidemiological, surgical and histological parameters) were associated with fertility results.

CONCLUSIONS

The use of salpingo-oophorectomy rather than cystectomy should be preferred during conservative surgery for patients with MBOTs because it decreases the risk of recurrence and does not impair fertility.

BACKGROUND

Hysteroscopy is known as the most accurate test for diagnosing intrauterine pathology. To optimize fertility treatment, it is increasingly common to perform hysteroscopy as a routine procedure prior to IVF. However, literature on the reproducibility of screening hysteroscopy is lacking. Therefore, the aim of the study was to assess the intra- and inter-observer agreement in the individual evaluation of the uterine cavity using video recordings of hysteroscopy procedures in asymptomatic patients prior to IVF.

METHODS

Screening hysteroscopies of 123 unselected, asymptomatic, infertile women with an indication for IVF/ICSI treatment were recorded on DVD. After editing, the hysteroscopy performer and three other experienced gynecologists independently assessed all recordings, focusing on the appearance of predefined intrauterine abnormalities (i.e. endometrial polyps, myomas, adhesions or septa). The intra- and inter-observer agreement was calculated and expressed as perfect agreement and coefficient or intraclass correlation coefficient.

RESULTS

In total, 123 hysteroscopy procedures were recorded. After editing and selection, based on the record quality, 107 remained for assessment and analysis. The intraobserver agreement on the appearance of any of the predefined intrauterine abnormalities was substantial ( = 0.707), whereas the interobserver agreement was moderate ( = 0.491). Perfect agreement occurred only in 77.6% of the cases.

CONCLUSIONS

Interobserver agreement among experienced gynecologists appeared to be rather disappointing. The latter may have implications for the diagnostic accuracy of screening hysteroscopy prior to IVF, as well as for its clinical significance in IVF programs.

BACKGROUND

In some couples, not all retrieved oocytes mature, even after prolonged in vitro culture. The underlying mechanisms are not known, although ionophore treatment may alleviate metaphase I (MI) arrest in some mouse strains. We attempted to induce first polar body (PB) extrusion and fertilization using assisted oocyte activation (AOA) after ICSI in maturation-resistant human MI oocytes.

METHODS

Four ICSI patients are described in this retrospective study. A pilot study tested the calcium ionophore ionomycin (10 µM) on donated MI oocytes from patients with a normal number of metaphase II (MII) oocytes. Subsequently, ionomycin was used to induce first PB extrusion in two patients showing maturation-resistant MI oocytes. AOA, by calcium injection and ionomycin exposure, was applied when mature oocytes were available. Oocytes were analysed by polarized microscopy and immunostaining.

RESULTS

Ionomycin induced the first PB extrusion in MI oocytes from patients with a normal number of retrieved MII oocytes, while extended in vitro culture failed to achieve the MII stage. Similarly, ionomycin induced first PB extrusion in one of two patients with recurrent maturation-resistant MI oocytes. Use of ICSI combined with AOA on MII oocytes matured in vitro or in vivo resulted in failed or abnormal fertilization with no further embryo cleavage potential. Highly abnormal spindle and chromosome configurations were observed in MI maturation-resistant oocytes, in contrast to control MI oocytes.

CONCLUSIONS

Ionophore induced first PB extrusion in MI oocytes from patients without maturation arrest but to a lower extent in maturation-resistant MI oocytes. Immunofluorescence staining and confocal analysis revealed, for the first time, highly abnormal spindle/chromosomal structures that may be responsible for this maturation arrest.
