Development and validity testing of a matrix to evaluate maturity of clinical pathways: a case study in Saskatchewan, Canada.

BACKGROUND: Healthcare systems are transforming into learning health systems that use data-driven and research-informed approaches to achieve continuous improvement. One of these approaches is the use of clinical pathways, which are tools to standardize care for a specific population and improve healthcare quality. Evaluating the maturity of clinical pathways is necessary to inform pathway development teams and health system decision makers about required pathway revisions or implementation supports. In an effort to improve the development, implementation, and sustainability of provincial clinical pathways, we developed a clinical pathways maturity evaluation matrix. To explore the initial content and face validity of the matrix, we used it to evaluate a case pathway within a provincial health authority in Saskatchewan, Canada. METHODS: By using iterative consensus-based processes, we gathered feedback from stakeholders including patient and family partners, policy makers, clinicians, and quality improvement specialists, to rank, retain, or remove enablers and sub-enablers of the draft matrix. We tested the matrix on the Chronic Pain Pathway (CPP) for primary care in a local pilot area and revised the matrix based on feedback from the CPP development team leader. RESULTS: The final matrix contains five enablers (i.e., Design, Ownership and Performer, Infrastructure, Performance Management, and Culture), 20 sub-enablers, and three trajectory definitions for each sub-enabler. Supplemental documents were created for six sub-enablers. The CPP scored 15 out of 40 possible points of maturity. Although the pathway scored highest in the Design enabler (10/12), it requires more attention in several areas, specifically the Ownership and Performer and the Performance Management enablers, each of which scored zero. Additionally, the Infrastructure and Culture enablers scored 2/4 and 3/8 points, respectively. These areas of the CPP are in need of improvement in order to enhance the overall maturity of the CPP. CONCLUSIONS: We developed a clinical pathways maturity matrix to evaluate the various dimensions of clinical pathways' development and implementation. The goals of this initial work were to develop and validate a tool to assess the maturity and readiness of new or existing pathways and to track pathways' revisions and improvements.

The diagnostic value of N-terminal pro-brain natriuretic peptide in differentiating cardioembolic ischemic stroke.

BACKGROUND: There has been debate regarding whether natriuretic peptides can be used as a marker to distinguish cardioembolic (CE) origin of ischemic stroke from other subtypes. Therefore, the aim of this study was to study the value of N-terminal pro B-type natriuretic peptide (NT-proBNP) in differentiating CE from other subtypes of stroke in patients with acute ischemic stroke. METHODS: All 125 consecutive patients with acute ischemic stroke in a 1-year period were included. Admission blood samples of all patients were analyzed for the serum level of NT-proBNP. Patients were evaluated for etiology of stroke by imaging modalities and classified based on Trial of Org 10172 in Acute Stroke Treatment criteria. Medical history and risk factors for vascular diseases were also obtained. Receiver operating characteristic (ROC) analysis was used for estimating the diagnostic performance of NT-proBNP levels. RESULTS: Patients were a mean of 67.5 ± 12.6 years of age, and 60 (48%) were men. The most frequent subtype of stroke (57 patients) was CE (45.6%). Levels of NT-proBNP at admission were significantly higher in the CE group (P = .001). After omitting confounding variables, NT-proBNP levels and age were independent predictors of CE stroke subtype. ROC analysis revealed that the diagnostic performance of NT-proBNP levels (area under the curve), optimum cutoff point and its sensitivity and specificity were 0.882 ± 0.031pg/mL, 342 pg/mL, 93%, and 75%, respectively. CONCLUSIONS: NT-proBNP has an acceptable diagnostic value in distinguishing CE ischemic stroke from other subtypes. It can be used to differentiate the stroke subtype and facilitate the treatment process in these patients.

Developing a patient-oriented realist evaluation for COVID-19 vaccine implementation in Saskatchewan: a methodologic framework.

BACKGROUND: There is an urgent need to inform decision-making and safe delivery of vaccines in a timely manner. Our objective is to describe the methods we used to perform a patient-oriented realist evaluation of COVID-19 vaccination implementation in Saskatchewan, Canada, in order to understand the underlying mechanisms and contexts of vaccination implementation and vaccine uptake. METHODS: This methodology paper describes a patient-oriented, realist, mixed-method evaluation to assess COVID-19 vaccination implementation in Regina, Saskatoon and Prince Albert, Saskatchewan. The study comprised 3 iterative phases guided by Realist And Meta-narrative Evidence Synthesis: Evolving Standards II (RAMESES II). In phase 1 (January-February 2021), we developed the initial program theory, in phase 2 (March-May 2021), we tested and refined the initial program theory, and in phase 3 (June-July 2021), we established the final program theory. Three patient and family partners with different backgrounds and experiences were selected purposively from various locations (urban and rural) in Saskatchewan to engage collaboratively in the evaluation. Data analysis and synthesis occurred at all 3 phases of the project. We analysed qualitative data from phases 2 and 3 using a "retroductive" approach. We used quantitative data to compare outcomes from the 3 sites. INTERPRETATION: This protocol describes how we developed a final program theory for COVID-19 vaccination implementation with patient and family partners to show for whom, under what circumstances, how and why Saskatchewan's COVID-19 vaccination program has led to vaccine uptake. With patient and family partners' engagement, the evaluation findings will be shared with the Saskatchewan Health Authority and provincial government policy-makers and communications departments, published in peer-reviewed journals, presented at provincial or national conferences, and disseminated through any additional media identified by the patient and family partners.
