Faecal output will be recorded by nursing staff using a stool chart validated for use in this patient group. The chart will aid in the characterization of faecal frequency, consistency, and weight, which are then summarized into a daily stool score. A score of 15 or more is used to indicate diarrhoea (Whelan, Judd, Preedy, & Taylor, 2008). Patients will be visited once, daily during weekdays and contacted by telephone during weekends to monitor data recording by the nursing staff.
