Constipation is a distressing symptom, common in many patient groups and traditionally treated by nurses. Ambiguity concerning limits of the nurse's role in treating constipation exists and guidelines are scarce. Theoretically constipation is largely preventable, but acute episodes arise for a number of reasons and often need prompt treatment. This article describes the development of a local protocol which empowers appropriately trained community nurses to treat adult patients with acute constipation. A flow chart was used to define the guidelines. Implementation of the protocol is briefly discussed in relation to other current local initiatives.
