We sought to evaluate whether the presence of condition-specific obstetric protocols within a hospital was associated with better maternal and neonatal outcomes.
This was a cohort study of a random sample of deliveries performed at 25 hospitals over 3 years. Condition-specific protocols were collected from all hospitals and categorized independently by 2 authors. Data on maternal and neonatal outcomes, as well as data necessary for risk adjustment were collected. Risk-adjusted outcomes were compared according to whether the patient delivered in a hospital with condition-specific obstetric protocols at the time of delivery.
Hemorrhage-specific protocols were not associated with a lower rate of postpartum hemorrhage or with fewer cases of estimated blood loss >1000 mL. Similarly, in the presence of a shoulder dystocia protocol, there were no differences in the frequency of shoulder dystocia or number of shoulder dystocia maneuvers used. Conversely, preeclampsia-specific protocols were associated with fewer intensive care unit admissions (odds ratio, 0.28; 95% confidence interval, 0.18-0.44) and fewer cases of severe maternal hypertension (odds ratio, 0.86; 95% confidence interval, 0.77-0.96).
The presence of condition-specific obstetric protocols was not consistently shown to be associated with improved risk-adjusted outcomes. Our study would suggest that the presence or absence of a protocol does not matter and regulations to require protocols are not fruitful.
我们试图评估医院内特定情况的产科诊疗方案是否与更好的孕产妇和新生儿结局相关。
这是一项队列研究,对25家医院3年内随机抽取的分娩病例进行研究。从所有医院收集特定情况的诊疗方案,并由两名作者独立分类。收集孕产妇和新生儿结局数据以及风险调整所需的数据。根据患者分娩时是否在设有特定情况产科诊疗方案的医院分娩,对风险调整后的结局进行比较。
针对出血的诊疗方案与较低的产后出血率或估计失血量>1000 mL的病例数减少无关。同样,在有肩难产诊疗方案的情况下,肩难产的发生率或使用的肩难产处理方法数量没有差异。相反,针对子痫前期的诊疗方案与较少的重症监护病房收治率(比值比,0.28;95%置信区间,0.18 - 0.44)和较少的严重孕产妇高血压病例(比值比,0.86;95%置信区间,0.77 - 0.96)相关。
特定情况的产科诊疗方案并非始终显示与改善风险调整后的结局相关。我们的研究表明诊疗方案的有无无关紧要,要求制定诊疗方案的规定并无成效。
