Guideline-based quality indicators for early pregnancy assessment units.

RESEARCH QUESTION: What valid guideline-based quality indicators can measure quality of care in early pregnancy assessment units (EPAU)? DESIGN: The systematic RAND-modified Delphi method was used to develop an indicator set from four evidence-based guidelines. An international expert panel was assembled to extract recommendations from these guidelines to establish quality indicators. RESULTS: A total of 119 recommendations were extracted. Eleven recommendations received a high median score and top five score above the 75th percentile and were selected as key recommendations. The expert panel reassessed 15 high score recommendations and top five score between the 50th and 75th percentile as well as one high score recommendation without consensus. Eight of these 16 recommendations were selected in the second round as key recommendations. The key recommendations were formulated into a set of 19 quality indicators, summarized as follows: women referred to an EPAU could be seen within 24 h and receive a clear explanation on treatment options; designated senior staff members could be responsible for the unit and staff could have had ultrasound training; protocols could be available for daily practice covering all treatment options for miscarriage and ectopic pregnancy; and an EPAU could have access to urine pregnancy testing and serum HCG assays. CONCLUSIONS: Nineteen quality indicators to measure early pregnancy care provided by EPAU were identified.

Early pregnancy care over time: should we promote an early pregnancy assessment unit?

In this observational study, the effect of the introduction of the first Early Pregnancy Assessment Unit (EPAU) in a university hospital in The Netherlands in 2008 on early pregnancy care is analysed. Derivatives of quality of care were measured before and after the establishment of the EPAU, with the aim of reducing unnecessary care. Care within three time periods was measured: 2006, 2009 and 2012. In 2006, 14% of women who had experienced a miscarriage were admitted to the hospital, whereas in 2009 and 2012 no women were admitted. The surgical management rate for miscarriage decreased from 79% (2006) to 6% (2009) and 28% (2012). Karyotyping of couples who had experienced recurrent miscarriage decreased from 100% (2006) to 17% (2009) and 33% (2012). The surgical management rate for ectopic pregnancy decreased from 50% (2006) to 25% (2009) and 29% (2012). The mean total cost per woman treated in 2006 was €1111 (95% CI €808 to 1426), €436 (95% CI €307 to 590) in 2009 and €633 (95% CI €586 to 788) in 2012. We can therefore conclude that an EPAU results in higher quality and cost-effective care, and has a positive effect on early pregnancy care.

Genetics of early miscarriage.

A miscarriage is the most frequent complication of a pregnancy. Poor chromosome preparations, culture failure, or maternal cell contamination may hamper conventional karyotyping. Techniques such as chromosomal comparative genomic hybridization (chromosomal-CGH), array-comparative genomic hybridization (array-CGH), fluorescence in situ hybridization (FISH), multiplex ligation-dependent probe amplification (MLPA) and quantitative fluorescent polymerase chain reaction (QF-PCR) enable us to trace submicroscopic abnormalities. We found the prevalence of chromosome abnormalities in women facing a single sporadic miscarriage to be 45% (95% CI: 38-52; 13 studies, 7012 samples). The prevalence of chromosome abnormalities in women experiencing a subsequent miscarriage after preceding recurrent miscarriage proved to be comparable: 39% (95% CI: 29-50; 6 studies 1359 samples). More chromosome abnormalities are detected by conventional karyotyping compared to FISH or MLPA only (chromosome region specific techniques), and the same amount of abnormalities compared to QF-PCR (chromosome region specific techniques) and chromosomal-CGH and array-CGH (whole genome techniques) only. Molecular techniques could play a role as an additional technique when culture failure or maternal contamination occurs: recent studies show that by using array-CGH, an additional 5% of submicroscopic chromosome variants can be detected. Because of the small sample size as well as the unknown clinical relevance of these molecular aberrations, more and larger studies should be performed of submicroscopic chromosome abnormalities among sporadic miscarriage samples. For recurrent miscarriage samples molecular technique studies are relatively new. It has often been suggested that miscarriages are due to chromosomal abnormalities in more than 50%, but the present review has determined that chromosomal and submicroscopic genetic abnormalities on average are prevalent in maximally half of the miscarriage samples.
