RESUMEN
Introduction: Evaluating a learning health system (LHS) encourages continuous system improvement and collaboration within the healthcare system. Although LHS is a widely accepted concept, there is little knowledge about evaluating an LHS. To explore the outputs and outcomes of an LHS model, we evaluated the COVID-19 Evidence Support Team (CEST) in Saskatchewan, Canada, an initiative to rapidly review scientific evidence about COVID-19 for decision-making. By evaluating this program during its formation, we explored how and to what extent the CEST initiative was used by stakeholders. An additional study aim was to understand how CEST could be applied as a functional LHS and the value of similar knowledge-to-action cycles. Methods: Using a formative evaluation design, we conducted qualitative interviews with key informants (KIs) who were involved with COVID-19 response strategies in Saskatchewan. Transcripts were analyzed using reflexive thematic analysis to identify key themes. A program logic model was created to represent the inputs, activities, outputs, and outcomes of the CEST initiative. Results: Interview data from 11 KIs were collated under three overarching categories: (1) outputs, (2) short-term outcomes, and (3) long-term outcomes from the CEST initiative. Overall, participants found the CEST initiative improved speed and access to reliable information, supported and influenced decision-making and public health strategies, leveraged partnerships, increased confidence and reassurance, and challenged misinformation. Themes relating to the long-term outcomes of the initiative included improving coordination, awareness, and using good judgment and planning to integrate CEST sustainably into the health system. Conclusion: This formative evaluation demonstrated that CEST was a valued program and a promising LHS model for Saskatchewan. The future direction involves addressing program recommendations to implement this model as a functional LHS in Saskatchewan.
RESUMEN
OBJECTIVES: Evidence suggests that prehospital point of care ultrasound (POCUS) may change patient management. It serves as an aid in triage, physical examination, diagnosis, and patient disposition. The rate of adoption of POCUS among aeromedical services throughout Canada is unknown. The objective of this study was to describe current POCUS use among Canadian aeromedical services providers. METHODS: This is a cross-sectional observational study. A survey was emailed to directors of government-funded aeromedical services bases in Canada. Data were analyzed using descriptive statistics. RESULTS: The response rate was 82.3% (14/17 aeromedical services directors), representing 41 of 46 individual bases. POCUS is used by aeromedical services in British Columbia, Alberta, Saskatchewan, and Manitoba. New Brunswick, Nova Scotia, Prince Edward Island, and Yukon reported they are planning to introduce POCUS within the next year. Ontario and Newfoundland reported they are not using POCUS and are not planning to introduce it. British Columbia is the only province currently using POCUS on fixed-wing aircraft. Most commonly reported frequency of POCUS use on missions was <25%. Most useful applications are assessment for pneumothorax, abdominal free fluid, and cardiac standstill. The most common barrier to POCUS use is cost of training and maintenance of competence. CONCLUSIONS: Prehospital POCUS is available in Western Canada with one third of the Canadian population having access to aeromedical services using ultrasound. The Maritimes and the Yukon Territory will further extend POCUS use on fixed-wing aircraft. While there are barriers to POCUS use, those bases that have adopted POCUS consider it valuable.
