Authority Mechanisms

Controlled Acts
 
Controlled acts are health care actions that are considered potentially harmful if performed by unqualified persons. The Regulated Health Professions Act sets out the controlled acts that should only be performed by someone with the legal authority to do so.

Dietitians have been granted the legal authority under the Dietetics Act to perform only one controlled act, skin pricking, which falls within the controlled act of performing a procedure below the dermis. This authority allows RDs to take blood samples by skin pricking for the purpose of monitoring capillary blood readings while practicing dietetics: 
Authorized act
 
3.1 In the course of engaging in the practice of dietetics, a member is authorized, subject to the terms, conditions and limitations imposed on his or her certificate of registration, to take blood samples by skin pricking for the purpose of monitoring capillary blood readings. 2009, c. 26, s. 7. 2


Delegation of Controlled Acts

The authority to perform most of the controlled acts can be delegated to another person including a regulated health professional as long as the delegation is made "in accordance with any applicable regulations under the health profession act governing the member's profession" (RHPA S28. (1))
 
Registered Dietitians can be given the authority to order diagnostic procedures and treatments. This authority is transferred through a medical directive. The College of Dietitians of Ontario supports the delegation of controlled acts to Registered Dietitians as long as the dietitian has or acquires the competencies to perform the controlled act safely.
