| Summary: | Abstract Background Evidenced-based practice is a key component of quality care. However, studies in the Philippines have identified gaps between evidence and actual maternity practices. This study aims to describe the practice of evidence-based intrapartum care and its associated factors, as well as exploring the perceptions of healthcare providers in a tertiary hospital in the Philippines. Methods A mixed-methods study was conducted, which consisted of direct observation of intrapartum practices during the second and third stages, as well as semi-structured interviews and focus group discussions with care providers to determine their perceptions and reasoning behind decisions to perform episiotomy or fundal pressure. Univariate and multivariate logistic regression were used to analyse the relationship between observed practices and maternal, neonatal, and environmental factors. Qualitative data were parsed and categorised to identify themes related to the decision-making process. Results A total of 170 deliveries were included. Recommended care, such as prophylactic use of oxytocin and controlled cord traction in the third stage, were applied in almost all the cases. However, harmful practices were also observed, such as intramuscular or intravenous oxytocin use in the second stage (14%) and lack of foetal heart rate monitoring (57%). Of primiparae, 92% received episiotomy and 31% of all deliveries received fundal pressure. Factors associated with the implementation of episiotomy included primipara (adjusted Odds Ratio [aOR] 62.3), duration of the second stage of more than 30 min (aOR 4.6), and assisted vaginal delivery (aOR 15.0). Factors associated with fundal pressure were primipara (aOR 3.0), augmentation with oxytocin (aOR 3.3), and assisted delivery (aOR 4.8). Healthcare providers believe that these practices can prevent laceration. The rate of obstetric anal sphincter injuries (OASIS) was 17%. Associated with OASIS were assisted delivery (aOR 6.0), baby weights of more than 3.5 kg (aOR 7.8), episiotomy (aOR 26.4), and fundal pressure (aOR 6.2). Conclusions Our study found that potentially harmful practices are still conducted that contribute to the occurrence of OASIS. The perception of these practices is divergent with current evidence, and empirical knowledge has more influence. To improve practices the scientific evidence and its underlying basis should be understood among providers.
