Brief Summary

The split-dose regimen (SpD) has demonstrated its superiority over the day-before regimen (DB) in determining a better colon cleansing and is considered the standard bowel preparation for colonoscopies by the American Society for Gastrointestinal Endoscopy (ASGE) and the European Society of Gastrointestinal Endoscopy (ESGE) guidelines. However its application is still suboptimal due to concerns about patient acceptability, fluid aspiration due to residual gastric contents and challenging viability for early morning colonoscopies. Barriers precluding the prescription of SpD have been explored in few studies mainly in the setting of auditing of current practice, while corrective measure aiming at changing this practice have been prospectively tested in very few, small and selected, cohorts. The present study has the aim of surveying split-dose regimen adoption rate among several endoscopic centres before and after an improvement phase following a plan-do-study-act approach, in order to analyse and correct factors preventing its adoption. A multivariate analysis was planned in order to use collected data to infer factors favouring and limiting split-dose regimen adoption.
