Conditional logistic regression was used to estimate the effects of drug use on postpartum haemorrhage and atonic postpartum haemorrhage. Results There was an unexpected non\linear, declining temporal pattern in postpartum haemorrhage and atonic postpartum haemorrhage between 1998 and 2009. Use of antidepressants (mainly selective serotonin reuptake inhibitors) was associated with higher rates of postpartum haemorrhage [adjusted rate ratio (aRR) 1.48, 95% confidence interval (CI) 1.23, 1.77] and atonic postpartum haemorrhage [aRR 1.40, 95% CI 1.13, 1.74]. Thrombocytopenia was also associated with higher rates of postpartum haemorrhage [aRR 1.52, 95% CI 1.16, 2.00]. There were no statistically significant drug interactions. Adjustment for maternal factors and drug use had little effect on temporal trends in postpartum haemorrhage and atonic postpartum haemorrhage. Conclusions Although antidepressant use and thrombocytopenia were associated with higher rates of atonic postpartum haemorrhage, antidepressant and other drug use did not explain temporal trends in postpartum haemorrhage. strong class=”kwd-title” Keywords: Atonic postpartum hemorrhage, temporal trends, etiology, selective serotonin reuptake inhibitors, thrombocytopenia Increases in atonic postpartum haemorrhage (PPH) and severe atonic PPH have been reported in several countries including Australia, Canada, Ireland, Scotland, Norway, Sweden, and the US since the 1990s.1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 These trends are important from a clinical and populace health standpoint, as PPH in high\income countries is a cause of moderate and severe maternal morbidity (and rarely maternal mortality). However, several studies that have investigated changes in various maternal and obstetric factors have not identified any specific cause for the rising rates. Controlling for changes in maternal age, parity, pre\pregnancy weight, multiple pregnancy, previous caesarean delivery, labour induction, labour augmentation, caesarean delivery, and other risk factors has not adequately explained the temporal increases in atonic PPH.1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 However, many of these investigations used large populace\based data sets with inadequate detail on pre\pregnancy weight and labour management. Therefore, it remains unclear whether temporal increases in atonic PPH represent true increases in haemorrhage due to changes in maternal characteristics, obstetric practice or other extraneous factors, or artefacts due to subtle changes in the diagnosis of this difficult to diagnose condition. Nevertheless, the failed attempts at explaining the recent increase in atonic PPH have led to the aetiologic focus shifting from maternal and obstetric factors to potential drug effects and drug interactions.9 The absence of reports of temporal increases in atonic PPH from low\ and middle\income countries (which are less medicalised) also raises the possibility of a drug effect or drug interaction. The use of pharmaceutical agents in pregnancy including selective serotonin reuptake inhibitors (SSRIs), aspirin, and other antiplatelet drugs, non\steroidal anti\inflammatory drugs (NSAIDs), and antihistamines has increased in high\income countries in recent decades,15, 16, 17, 18 and studies have shown increased rates of bleeding associated with the use of some of these agents either singly or in combination.19, 20, 21 Drug interactions and interactions between drugs and specific medical conditions (such as alcoholism, liver disease, and thrombocytopenia) are other potential explanations for increases in rates of atonic PPH. We therefore carried out a population\based study examining the effects of the above\mentioned drugs and medical conditions on rates and temporal trends in PPH. Methods This population\based study was carried out using the linked administrative database of the Qubec Pregnancy Cohort.22 This database is the product of a linkage of the physician claims database (Rgie de l’assurance maladie du Qubec, the RAMQ database), the hospitalisation database (the MED\ECHO database), and the vital statistics database (Institut de la statistique du Qubec, the ISQ database) in Qubec, IC-87114 Canada. The prescription claims component of the RAMQ database included prospectively collected data on prescriptions filled by recipients of social assistance, and workers and their families who did not have access to a private drug insurance plan (in Qubec all citizens are insured for physician visits and hospitalisations, whereas recipients of social assistance and workers and their families who do not have access to a private drug insurance are also insured for outpatient drug costs); 36% of women between 15C45 years in Qubec were included in such coverage.22 The MED\ECHO database recorded acute care hospitalisation data for all Qubec residents. Information on hospitalisations for childbirth, including maternal characteristics, gestational age at delivery, and diagnoses and procedures was included in the database.22 Gestational age in the Qubec Pregnancy Cohort was defined as the duration between the first day of the last menstrual period and delivery, confirmed by ultrasound. The vital statistics database included information on all live births and stillbirths. Pregnancy\related variables in the cohort, such as birth weight, gestational age, and date of delivery, as well as specific International Classification of Diseases (ICD) codes, have been previously validated against patient charts.23, 24 Prescription information in.Testing of the study hypotheses related to aspirin and NSAIDs should be regarded as preliminary, as our data source exclusively recorded medications dispensed by prescription. serotonin reuptake inhibitors) was associated with higher rates of postpartum haemorrhage [modified rate percentage (aRR) 1.48, 95% confidence interval (CI) 1.23, 1.77] and atonic postpartum haemorrhage [aRR 1.40, 95% CI 1.13, 1.74].
