Impact of electronic and blended learning programs for manual perineal support on incidence of obstetric anal sphincter injuries: a prospective interventional study.

ABSTRACT: BACKGROUND:Obstetric anal sphincter injuries (OASIS) are associated with anal incontinence, dyspareunia and perineal pain. Bimanual perineal support technique (bPST) prevents OASIS. The aim of this study was to assess the effect of two different bPST training-methods on OASIS incidence. METHODS:This is a prospective-interventional quality improvement study conducted in two Palestinian maternity units between June 1 2015 and December 31 2016. Women having spontaneous or operative vaginal-delivery at ?24 gestational-weeks or a birthweight of ?1000 g (n?=?1694) were recruited and examined vaginally and rectally immediately after vaginal birth by a trained assessor. Data on baseline OASIS incidence were collected during Phase-1 of the study. Subsequently, birth attendants in both maternity units were trained in bPST using two training modalities. A self-directed electronic-learning (e-learning) using an animated video was launched in phase-2 followed by a blended learning method (the animated e-learning video+ structured face-to-face training) in phase-3. OASIS incidence was monitored during phases-2 and 3. Variations in OASIS incidence between the three phases were assessed using Pearson-?2-test (or Fisher's-Exact-test). The impact of each training-method on OASIS incidence was assessed using logistic-regression analysis. RESULTS:A total of 1694 women were included; 376 in phase-1, 626 in phase-2 and 692 in phase-3. Compared to Phase-1, OASIS incidence was reduced by 45% (12.2 to 6.7%, aOR: 0.56, CI; 0.35-0.91, p?=?0.018) and 74% (12.2 to 3.2%, aOR, 0.29, CI; 0.17-0.50, p?

Project description:ObjectiveTo explore the impact of a training intervention on obstetric anal sphincter injuries' (OASIS) detection rate.DesignProspective quality improvement interventional study.SettingSix secondary and tertiary maternity units in Palestine.PopulationWomen having singleton vaginal births ?23?weeks' gestation or babies weighing ?500?g (n=22 922). Caesarean births (n=5431), multiple gestations (n=443) and vaginal births of unregistered perineum status (n=800) were excluded.InterventionsTraining programme for enhancing OASIS detection was conducted between 31 January and 31 December 2015. International experts delivered 2-day standardisation workshop teaching OASIS diagnosis and repair to each maternity unit. They also provided additional training to three research fellows employed in three of the maternity units. This was followed by 13-week period of data collection (phase 1). Research fellows then delivered training intervention over 15-week interval (phase 2), including theoretical teaching and 'onsite' training in perineal trauma assessment within the six maternity units. Finally, 13-week postintervention observation (phase 3) followed.Primary outcome measureOASIS rates were used as surrogate for OASIS recognition. OASIS rates were compared between different phases and between the two maternity unit groups (research fellow and non-research fellow based) using Pearson's ?² test.ResultsA total 22 922 women were included. Among primiparous women, OASIS rate was higher in phase 2 (2.8%, p<0.001) and phase 3 (3.1%, p<0.001) than phase 1 (0.5%). However, no significant differences were detected in the rates of severe OASIS (third-degree 3c and fourth-degree tears) between phase 1 and 2 (0.5% vs 0.3%), because this would have required at least 103 women with severe OASIS to be included in each phase. Among parous women, OASIS rate was significantly higher in phase 2 (0.6%, p=0.002) but not in phase 3 (0.4%, p=0.071) compared with phase 1 (0.2%). Research fellows' maternity units showed higher OASIS rates among primiparous women in phase 2 (3.6% vs 1.4%, p=0.001) and phase 3 (4.3% vs 0.8%, p<0.001) than non-research fellows' maternity units.ConclusionsThis work is basically an epidemiological study which has identified the prevalence of perineal lacerations and their severity on a large sample of women representative of an entire geographical ethnic region. The quality improvement intervention improved OASIS detection mainly in the research fellows' maternity units. Regular mandatory national programmes in obstetric perineal trauma assessment and management by local champions are essential to mitigate the risk of missing significant degrees of trauma.

Project description:BackgroundThe potential protective effect of mediolateral episiotomy for obstetrical anal sphincter injuries (OASIs) remains controversial during operative vaginal delivery because of the difficulties to take into account the risk factors and clinical conditions at delivery; in addition, little is known about the potential benefits of mediolateral episiotomy on neonatal outcomes. The objectives were to investigate the associations between mediolateral episiotomy and both OASIs and neonatal outcomes, using propensity scores.MethodsWe performed a retrospective population-based observational study from a perinatal registry that includes all births in a French region between 2010 and 2017. All nulliparous women with singleton pregnancy delivering by operative vaginal deliveries at 37 weeks gestational age or later were included. Inverse-probability-of-treatment weighting with propensity scores was used to minimize indication bias. OASIs was defined as third and fourth-degree tears according to Royal College of Obstetricians and Gynecologists. Two neonatal outcomes were studied: condition at birth (5-min Apgar score less than 7 and/or umbilical artery pH less than 7.10), and admission to neonatal intensive care unit.ResultsThe study population consisted of 7589 women; 2880 (38.0%) received mediolateral episiotomy. After applying propensity scores, episiotomy was associated with a lower rate of OASIs in forceps/spatula delivery (2.3 vs 6.8%, Risk Ratio (RR) 0.38, 95% Confidence Interval (CI) 0.28-0.52) and in vacuum delivery (1.3 vs 3.4%, RR 0.27, 95% CI 0.20-0.38) as compared with no episiotomy. Mediolateral episiotomy was associated with better condition at birth in case of forceps/spatula delivery (4.5 vs 8.8%, RR 0.56, 95% CI 0.39-0.81). In cases of fetal distress (40.7%), mediolateral episiotomy was associated with better condition of infant at birth in women who delivered by forceps/spatula (4.2 vs 13.5%, RR 0.52, 95% CI 0.31-0.89). No association was found with neonatal unit admission (RR 0.93, 95% CI 0.50-1.74).ConclusionsUse of mediolateral episiotomy was associated with a lower rate of OASIs during operative vaginal delivery, and in infants it was associated with better condition at birth following forceps/spatula delivery.
