Description of intervention(s) / exposure
The rate and outcomes of Obstetric Anal Sphincter injury will be observed in relation to the quality of care measures.
Both patients and staff will be participants. Prospectively both participants groups will be complete de-identified questionnaires. Staff complete a one-off questionnaire with patients completing an antenatal and postnatal questionnaire. Retrospectively, de-identified patient data and clinical care information will be collected from medical records from 2017/18 in each recruitment hospital site/ward.

Statistical methods / analysis
We plan to conduct a series of statistical analyses with the aim of answering our primary research questions. This will include descriptive, bivariate and multivariate analysis along with multilevel modelling.

Descriptive statistics will be used to summarise the spread, frequencies or distributions of the variables of interest in our study. Bivariate analysis, testing for associations between variables, will be carried out along with multivariate modelling. Multivariate modelling will take the form of a multilevel or hierarchical model in the first instance; with hospitals as the level two unit and departments as level one. This type of regression will adjust for both hospital and department level covariates. Subject to the results of this modelling, the levels may be changed to have individual patient outcomes as level one or alternatively a single level model utilised. By employing multilevel methods investigators will be able to identify the amount of variation in outcomes attributed to the hospital and department level, as well as what factors contribute to this variation.
