Using a Triple Aim Approach to Implement "Less-is-More Together" and Smarter Medicine Strategies in an Interprofessional Outpatient Setting: Protocol for an Observational Study.

Background: Increased awareness of the world's problematic growing health care expenditure and health care shortages requires sustainable use of available resources. To promote cultural changes in medical mindsets, societies representing medical specialties have developed new Choosing Wisely strategies. The Valais Medical Society and the Valais Pharmacy Association have developed an interprofessional collaboration project entitled "Less-is-more Together-PPI" to analyze and optimize change management practices focusing on the prescription and deprescription of proton pump inhibitors (PPIs).
