Final answer:
In healthcare or psychology, a systemic and unique approach to method and procedure based on principles is known as a model, commonly associated with evidence-based practice, which integrates research, expertise, and patient preferences to ensure effective care.
Step-by-step explanation:
A systemic and unique approach to method, procedure and technique based on certain principles is commonly known as a model. In the context of healthcare or psychology, this term can refer to evidence-based practice, which is a decision-making process that integrates the best available research, clinician expertise, and patient preferences and values. Evidence-based practice is an important approach to delivering high-quality care, using methods and procedures that have been proven to be effective through rigorous research.
The scientific method is a systematic procedure that scientists use to conduct research, which includes observation, forming a hypothesis, testing through experimentation, analyzing results, and drawing conclusions. This is the core of evidence-based practice in medicine and psychology, where treatments and interventions are evaluated for their effectiveness based on scientific evidence.
