Abstract
Background: There is an evidence-practice gap between guidelines for diagnosing pulmonary embolism (PE) and emergency physician practice. This is concerning because computed tomography (CT) scanning is being overused to exclude PE in the emergency department (ED). It is possible that the answer behind this lies within the physician-patient relationship. Past research on shared decision-making strategies have shown to decrease use of hospital resources, and improve patient outcomes.
Objective: The aim of this three-part MSc thesis was to achieve a patient-centered approach to the testing of PE in the ED.
Method: 1) A systematic review on existing shared decision-making models used for testing and/or treatment of medical decisions in the ED was conducted. 2) Qualitative interviews with ED patients being tested for PE identified patient-specific values and preferences which may present as barriers to patient-centered care in the ED. 3) Both the systematic review and patient interviews informed the development of a new shared information tool to be used in the ED.
Results: The systematic review found that shared decision-making interventions in ED patients tested for acute coronary syndrome and clinically-important traumatic brain injuries can potentially reduce hospital admissions and increase discharge rates without negatively affecting health outcomes. The qualitative interviews highlighted four major themes: 1) patient satisfaction comes from addressing their primary concern; 2) preference for imaging over clinical examination; 3) patients expect 100% certainty when given a diagnosis; and 4) patients expect individualized care throughout their entire ED visit. This data led to the formation of a shared information sheet which ensures that testing decisions for low-risk PE patients align with patient-specific values.
Conclusion: By placing the focus on patient-centered care, this study incorporates evidence-based medicine with patient priorities in order to improve patient outcomes in the ED.
