A Program is a plan-of-action that is developed in response to a community need, problem, or issue. There is an intention for change, with goals, objectives, outcomes, and indicators to measure progress towards the desired end. We can think of a Program as the bubble within which many different Services are delivered to the patient in order to meet the Program's goals.
Example: The Memory Clinic Program uses the Services of Cognitive Testing, Family Counselling, Medication Review, Occupational Therapist Assessment, and others in order to reach the goal of providing early diagnosis, the objective of providing holistic care, and the outcome of keeping elderly patients living in their homes for as long as possible.
A Service is an activity or set of activities that are beneficial to the patient, but have not been structured in a way that would allow change to be measured. Services are the activities provided to a patient in order to reach the goals, objectives, and outcomes of a Program.
Example: Gathering information from a patient, assessing their needs, and providing them with the information and resources they need to help them make healthy living choices.
