INTRODUCTION Centralized intake is integral to healthcare systems to support timely access to appropriate health services. The aim of this study was to develop key performance indicators (KPIs) to evaluate centralized intake systems for patients with osteoarthritis (OA) and rheumatoid arthritis (RA). METHODS Phase 1 involved stakeholder meetings including(More)
We prove that the resonance counting functions for Schrödinger operators H V = −∆ + V on L 2 (R d), for d ≥ 2 even, with generic, compactly-supported, real-or complex-valued potentials V , have the maximal order of growth d on each sheet Λm, m ∈ Z\{0}, of the logarithmic Riemann surface. We obtain this result by constructing, for each m ∈ Z\{0}, a(More)
RATIONALE, AIMS AND OBJECTIVES Persistently long waiting times for hip and knee total joint arthroplasty (TJA) specialist consultations have been identified as a problem. This study described referral processes and practices, and their impact on the waiting time from referral to consultation for TJA. METHODS A mixed-methods retrospective study(More)
We describe the generic behavior of the resonance counting function for a Schrödinger operator with a bounded, compactly-supported real or complex valued potential in d ≥ 1 dimensions. This note contains a sketch of the proof of our main results [5, 6] that generically the order of growth of the resonance counting function is the maximal value d in the odd(More)
Despite various health system improvements across Alberta, the wait times benchmark was not being met for all patients requiring hip or knee arthroplasty. Alberta Health Services Bone and Joint Clinical Network working groups, in collaboration with other provincial organizations, gained consensus on the development and implementation of a set of provincial(More)
Suppose that (X, g) is a conformally compact (n + 1)-dimensional manifold that is hyperbolic near infinity in the sense that the sectional curvatures of g are identically equal to minus one outside of a compact set K ⊂ X. We prove that the counting function for the resolvent resonances has maximal order of growth (n + 1) generically for such manifolds. This(More)
Performance management tools commonly used in business, such as incentives and the balanced scorecard, can be effectively applied in the public healthcare sector to improve quality of care. The province of Alberta applied these tools with the Institute for Health Improvement Learning Collaborative method to accelerate adoption of a clinical care pathway for(More)
The purpose of this paper is to prove some results about quantum mechanical black box scattering in even dimensions d ≥ 2. We study the scattering matrix and prove some identities which hold for its meromorphic continuation onto Λ, the Riemann surface of the logarithm function. We study the multiplicities of the poles of the continued scattering matrix on(More)
