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). 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. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/13896.

Oculopharyngeal muscular dystrophy - an under-diagnosed disorder?

Oculopharyngeal muscular dystrophy (OPMD) is an autosomal dominant muscle disorder, usually of late onset. OPMD is among the few triplet repeat diseases/ polyalanine (poly(A)) expansion diseases for which the function of the mutated gene is quite well established. The disease is characterised by slowly progressive bilateral ptosis, dysphagia and proximal limb weakness, appearing after the age of 40 years. Prevalence and incidence of OPMD are low, but the disease occurs all over the world. The pedigrees of two Swiss kindred have been previously reported in Switzerland. In the last 2 years, accumulation of newly diagnosed cases in North-West Switzerland have been observed, which suggests that OPMD may be more prevalent than previously thought. Primary care providers, opthalmologists and neurologists that are alert for the almost specific combination of clinical signs, together with the availability of reliable genetic testing may help to recognise currently undiagnosed patients. They can advance knowledge and the characterisation of the OPMD population in Switzerland. Since the number of disorders linked to poly(A) expansions is growing rapidly, the study of OPMD may contribute to the understanding of a large group of other developmental and degenerative diseases. On the basis of a patient with "classical" OPMD, this review summarises the clinical, therapeutic, epidemiological, pathomechanistic and genetic aspects of OPMD, provides practical information about the differential diagnosis of OPMD, and presents a survey of different investigational methods.

Factors influencing the pattern of imported malaria.

BACKGROUND: Data on imported malaria in industrialized areas are known to be incomplete because of underreporting and lack of homogeneity. These facts and the complexity of factors influencing the transmission of malaria render their interpretation difficult. The relevance of various factors is usually not fully considered, although their impact on recommendations for chemoprophylaxis may be important. METHODS: All malaria cases imported from Kenya from 1988 to 1996 that were reported to the Federal Office of Public Health of Switzerland were analyzed. The reciprocal impact on data interpretation with regard to Plasmodium species, chemoprophylaxis, onset of first symptoms after return, male or female sex, seasonal fluctuation, duration of stay, nationality groups, and fatal outcome was analyzed. RESULTS: Multivariate analysis showed a significant impact of Plasmodium species, regular chemoprophylaxis, and long duration of stay on the latency of malaria attacks. African origin and repeated stays were confounders with regard to adherence to chemoprophylaxis. The local situation of malaria transmission and the development of tourist figures were found to influence the evolution of malaria rates. These factors must be analyzed simultaneously to prevent errors in data interpretation. A higher proportion of tertian malaria cases (caused by Plasmodium vivax or Plasmodium ovale) than in previous reports was recorded owing to the impact of chemoprophylaxis and longer outbreak latencies. Seventy-five percent of tertian malaria cases were diagnosed within 6 months after return. CONCLUSIONS: Factors influencing the pattern of imported malaria must be assessed in relation to each other, especially if data from different countries and various chemoprophylaxis regimens are compared. Furthermore, regular malaria chemoprophylaxis with mefloquine given until 4 weeks after return from an endemic area is not adequate to prevent tertian malaria. Regular chemoprophylaxis was found to cause longer latencies for all malaria species.
