Development of a survey to support assessment of safety learning systems.

BACKGROUND: Patient safety learning systems play a critical role in supporting safety culture in healthcare organisations. A lack of explicit standards leads to inconsistent implementation across organisations, causing uncertainty about their roles and impact. Organisations can address inconsistent implementation by using a self-assessment tool based on agreed-on best practices. Therefore, we aimed to create a survey instrument to assess an organisation's approach to learning from safety events. METHODS: The foundation for this work was a recent systematic review that defined features associated with the performance of a safety learning system. We organised features into themes and rephrased them into questions (items). Face validity was checked, which included independent pre-testing to ensure comprehensibility and parsimony. It also included clinical sensibility testing in which a representative sample of leaders in quality at a large teaching hospital (The Ottawa Hospital) answered two questions to judge each item for clarity and necessity. If more than 20% of respondents judged a question unclear or unnecessary, we modified or removed that question accordingly. Finally, we checked the internal consistency of the questionnaire using Cronbach's alpha. RESULTS: We initially developed a 47-item questionnaire based on a prior systematic review. Pre-testing resulted in the modification of 15 of the questions, 2 were removed and 2 questions were added to ensure comprehensiveness and relevance. Face validity was assessed through yes/no responses, with over 80% of respondents confirming the clarity and 85% the necessity of each question, leading to the retention of all 47 questions. Data collected from the five-point responses (strongly disagree to strongly agree) for each question were used to assess the questionnaire's internal consistency. The Cronbach's alpha was 0.94, indicating a high internal consistency. CONCLUSION: This self-assessment questionnaire is evidence-based and on preliminary testing is deemed valid, comprehensible and reliable. Future work should assess the range of survey responses in a large sample of respondents from different hospitals.

Quality and Patient Safety Metrics: Developing a Structured Program for Improving Patient Care in the Department of Medicine at The Ottawa Hospital.

PROBLEM: Despite increasing recognition of the importance of quality and patient safety in academic medicine, challenges remain with ensuring physician participation in quality assurance and quality improvement efforts, such as lack of compensation and enabling resources. An organizational culture that includes physician leadership and a supportive infrastructure is needed to encourage physician backing of quality and patient safety initiatives. APPROACH: The authors describe the development of a robust quality and patient safety program in the Department of Medicine at The Ottawa Hospital over the past 7 years and highlight how the department changed its organizational culture by prioritizing quality and patient safety and establishing the necessary infrastructure to support this program. Program development was characterized by 4 overarching themes: incentives, administrative structure and physician leadership, training and support, and system enhancements. OUTCOMES: As a result of the program, the department broadly implemented a standardized framework for conducting quality committee meetings and morbidity and mortality rounds and reviewing patient safety incidents and patient experience across its 16 divisions. This has led to 100% departmental compliance on corporate quality assurance metrics each year (e.g., regular multidisciplinary divisional quality committee meetings), along with physician participation in formal quality improvement initiatives that align with larger corporate goals. NEXT STEPS: The authors reflect on lessons learned during the implementation of the program and the essential elements that contributed to its success. Next steps for the program include using a centralized repository of quality and patient safety data, including patient safety incident dashboards, to encourage greater divisional collaboration on quality improvement initiatives and continuous institutional learning over time. Another important avenue will be to create an academic hub for excellence in quality and a formal approach to reward and promote physicians for their quality work.

Test characteristics of point-of-care ultrasonography in patients with acute kidney injury.

BACKGROUND: Acute kidney injury is a common disorder that is associated with significant morbidity and mortality. Point-of-care ultrasonography (PoCUS) is an imaging modality performed at the bedside and is used to assess for obstructive causes of acute kidney injury. Little is known about the test characteristics of PoCUS in patients with acute kidney injury. OBJECTIVE: Our primary objective was to describe the test characteristics of PoCUS for the detection of hydronephrosis in patients presenting with acute kidney injury at our centre. Our secondary objective was to describe the current rate of use of PoCUS for this indication. RESULTS: In total, 7873 patients were identified between June 1, 2019 and April 30, 2021, with 4611 meeting inclusion criteria. Of these, 94 patients (2%) underwent PoCUS, and 65 patients underwent both PoCUS and reference standard, for a total of 124 kidneys included in our diagnostic accuracy analysis. The prevalence of hydronephrosis in our cohort was 33% (95% CI 25-41%). PoCUS had a sensitivity of 85% (95% CI 71-94%) and specificity of 78% (95% CI 68-87%) for the detection of hydronephrosis. CONCLUSION: We describe the test characteristics of PoCUS for the detection of hydronephrosis in a cohort of patients with acute kidney injury. The low uptake of this test presents an opportunity for quality improvement work to increase its use for this indication.
