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 (Preprint)


 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).
 
 
 OBJECTIVE
 This study aims to enhance interprofessional collaboration between physicians, pharmacists, and patients to optimize PPI use, avoid unnecessary treatments and improve therapeutic adherence to indicated therapies, and to analyze hindrances and facilitators to implementing interprofessional Less-is-more strategies in the field.
 
 
 METHODS
 Home-dwelling adults domiciled in Valais and prescribed PPIs in the last 6 months will be invited to participate in this observational study. The studied subpopulation will be constituted of consenting patients whose physicians and pharmacists also voluntarily agree to participate. The process of collecting, pooling, transmitting, evaluating, and protecting data has been validated by the Human Research Ethics Committee of the Canton Vaud.
 
 
 RESULTS
 The Primary Triple Aim outcome measures will be (1) population health: patient’s assessment of their own health, functional status, and disease burden using a monthly questionnaire for 6 months; Behavioral/physiological factors will be investigated using a final questionnaire at 6 months, (2) experience of care: assessment using a final questionnaire for participating patients, pharmacists and physicians, and an analysis of negative/positive experiences via 6 follow-up questionnaires, and (3) Per capita cost: participants’ fluctuating or decreasing PPI intake (number of pills/dosage) and an analysis of participants’ different categories following their medical prescription, in relation to possible bias effects on the overall drug intake of the population studied. Secondary outcomes will be participation rates; patient, physician, and pharmacist follow-up; and evaluations of participants' experiences and their perceived benefits, as well as whether the interprofessional process can be improved.
 
 
 CONCLUSIONS
 This project seeks a deeper understanding of how Less-is-more and smarter-medicine strategies are perceived by patients and health care providers in their daily lives in a very specific context. It will reveal some of the hindrances to and facilitators for efficient cultural change toward a more sustainable health care system. The results will be useful to optimize and scale up further Choosing Wisely approaches.
