Identifying the factors that influence midwives' perineal practice at the time of birth in the United Kingdom.

OBJECTIVE: The Obstetric Anal Sphincter Injuries (OASI) Care Bundle is designed to reduce the incidence of obstetric anal sphincter injuries. However, introducing behavioural change requires an understanding of current practice. This study aims to establish midwives practise at the time of birth, and the factors that influence this. DESIGN: Quantitative research - a national online survey. SETTING: Nationwide - United Kingdom (UK). Participants 563 midwives from across the UK. METHODS: An online survey of midwives' practice. Midwives were invited to participate through the Supervisor of Midwives network. Consent was sought on the landing page. Data analysis using descriptive and inferential statistics, with sub group analyses were used to explore variations in practice. Measurements Number of midwives using "hands on" the perineum and the influences on midwives' perineal practice at the time of birth. FINDINGS: Most midwives preferred to use "hands on" the perineum at the time of birth (61.4%). "Hands on" practise was significantly associated with where midwives worked (p<0.001), risk factors for OASI (p<0.001), and the approach that they were taught in their midwifery training (p
