ObjectiveTo assess the incidence of diarrhoea in intensive care patients with a length of stay (LOS) greater than 3 days who were receiving any type of enteral tube feeding, and to measure the effect of implementing a bowel management protocol.DesignA 2-year prospective audit, with an intervention after 12 months. Diarrhoea was defined as bowel activity exceeding three stools of any consistency per day, or three or more unformed stools (or 300 mL) per day, for two consecutive days.SettingA tertiary referral intensive care unit (ICU) in a large public hospital.SampleSix hundred fifty-six consecutive patients admitted to ICU with a LOS >3 days.InterventionA bowel management protocol was implemented to address both diarrhoea and constipation.Main Outcome MeasuresNumber of patients who experienced diarrhoea during their ICU stay; number of ICU patient-days on which diarrhoea occurred.ResultsAfter the protocol was implemented, diarrhoea was experienced by 13% fewer patients (p = 0.0002) and occurred on 8% fewer ICU days (p < 0.0001).ConclusionUse of an evidence-based protocol, and improved monitoring and reporting of bowel activity, can decrease the incidence of diarrhoea in ICU patients.
