Staff and institutional factors associated with substandard care in the management of postpartum hemorrhage

International audienceObjective: to identify staff and institutional factors associated with substandard care by midwives managing postpartum hemorrhage (PPH). Methods: A multicenter vignette-based study was e-mailed to a random sample of midwives at 145 French maternity units that belonged to 15 randomly selected perinatal networks. Midwives were asked to describe how they would manage two case-vignettes about PPH and to complete a short questionnaire about their individual (e.g., age, experience, and full-vs. parttime practice) and institutional (private or public status and level of care) characteristics. These previously validated case-vignettes described two different scenarios: vignette 1, a typical immediate, severe PPH, and vignette 2, a severe but gradual hemorrhage. Experts consensually defined 14 criteria to judge adherence to guidelines. The number of errors (possible range: 0 to 14) for the 14 criteria quantified PPH guideline adherence, separately for each vignette. Results: 450 midwives from 87 maternity units provided complete responses. Perfect adherence (no error for any of the 14 criteria) was low: 25.1% for vignette 1 and 4.2% for vignette 2. After multivariate analysis, midwives' age remained significantly associated with a greater risk of error in guideline adherence in both vignettes (IRR 1.19 [1.09; 1.29] for vignette 1, and IRR 1.11 [1.05; 1.18] for vignette 2), and the practice of mortality and morbidity reviews in the unit with a lower risk (IRR 0.80 [0.64; 0.99], IRR 0.78 [0.66; 0.93] respectively). Risk-taking scores (IRR 1.41 [1.19; 1.67]) and full-time practice (IRR 0.83 [0.71; 0.97]) were significantly associated with adherence only in vignette 1. Conclusions: Both staff and institutional factors may be associated with substandard care in midwives' PPH management
