Concealing medication in patients food: The Lancet.
Treolar et al, April 2001

A study of medication administration in care homes revealed that the practice of concealing medication in the food or drink of residents is widespread and occurred in 79% of the sample care homes questioned. 94% of care home workers believed that the practice was justified. In 1996, kellett reported the disciplinary action taken by a UK national health service (NHS) trust after a nurse had concealed haloperidol, prescribed by a consultant, in a patient's drink, to provide treatment in an urgent and complex clinical situation. Although the patient later expressed clear gratitude for the action taken, the nurse effectively lost her career, and the consultant was strongly censured. Another more recent report described the administration of clopazine in drink in an intensive psychiatric care unit.
