Choosing Wisely: An idea worth sustaining.

Health Serv Res 2021 Dec 2. Epub 2021 Dec 2.

Department of Surgery, North York General Hospital, Toronto, Ontario, Canada.

Objectives: To evaluate the sustainability potential of Choosing Wisely (CW) to address unnecessary medical care at Ontario community hospitals.

Data Sources/study Setting: Ontario community hospitals and their affiliated family health teams (FHTs).

Study Design: A mixed-methods study involving the administration of a validated sustainability survey to CW implementation teams followed by their participation in focus groups.

Data Collection/extraction Methods: Survey data were collected using an Excel file with an embedded, automated scoring system. We collated individual survey scores and generated aggregate team scores. We also performed descriptive statistics for quantitative data (frequencies, means). Qualitative data were triangulated with quantitative assessments to support data interpretations using the meta-matrix method.

Principal Findings: Fifteen CW implementation teams across four Ontario community hospitals and six affiliated primary care FHTs participated. CW priority areas investigated were de-prescribing of proton pump inhibitors (PPIs) and reducing Pre-Op testing and BUN/Urea lab testing. Survey results showed steady improvements in sustainability scores from baseline to final follow-up among most implementation teams: 10% increase for PPI de-prescribing (six FHTs) and 2% increase (three hospital teams); 18% increase in BUN/Urea lab testing (three hospital teams). Regardless of site or CW priority area, common facilitators were fit with existing processes and workflows, leadership support, and optimized team communication; common challenges were lack of awareness and buy-in, leadership engagement or a champion, and lack of fit with existing workflow and culture. All teams identified at least one challenge for which they co-designed and implemented a plan to maximize the sustainability potential of their CW initiative.

Conclusions: Evaluating the sustainability potential of an innovation such as Choosing Wisely is critical to ensuring that they have the best potential for impact. Our work highlights that implementation teams can be empowered to influence implementation efforts and to realize positive outcomes for their health care services and patients.

When should a diagnosis of influenza be considered in adults requiring intensive care unit admission? Results of population-based active surveillance in Toronto.

Crit Care 2011 Jul 28;15(4):R182. Epub 2011 Jul 28.

Mount Sinai Hospital, 600 University Avenue, Toronto, ON M5G 1X5, Canada.

Introduction: There is a paucity of data about the clinical characteristics that help identify patients at high risk of influenza infection upon ICU admission. We aimed to identify predictors of influenza infection in patients admitted to ICUs during the 2007/2008 and 2008/2009 influenza seasons and the second wave of the 2009 H1N1 influenza pandemic as well as to identify populations with increased likelihood of seasonal and pandemic 2009 influenza (pH1N1) infection.

Methods: Six Toronto acute care hospitals participated in active surveillance for laboratory-confirmed influenza requiring ICU admission during periods of influenza activity from 2007 to 2009. Nasopharyngeal swabs were obtained from patients who presented to our hospitals with acute respiratory or cardiac illness or febrile illness without a clear nonrespiratory aetiology. Predictors of influenza were assessed by multivariable logistic regression analysis and the likelihood of influenza in different populations was calculated.

Results: In 5,482 patients, 126 (2.3%) were found to have influenza. Admission temperature ≥38°C (odds ratio (OR) 4.7 for pH1N1, 2.3 for seasonal influenza) and admission diagnosis of pneumonia or respiratory infection (OR 7.3 for pH1N1, 4.2 for seasonal influenza) were independent predictors for influenza. During the peak weeks of influenza seasons, 17% of afebrile patients and 27% of febrile patients with pneumonia or respiratory infection had influenza. During the second wave of the 2009 pandemic, 26% of afebrile patients and 70% of febrile patients with pneumonia or respiratory infection had influenza.

Conclusions: The findings of our study may assist clinicians in decision making regarding optimal management of adult patients admitted to ICUs during future influenza seasons. Influenza testing, empiric antiviral therapy and empiric infection control precautions should be considered in those patients who are admitted during influenza season with a diagnosis of pneumonia or respiratory infection and are either febrile or admitted during weeks of peak influenza activity.

Canadian Association of General Surgeons and American College of Surgeons Evidence Based Reviews in Surgery. 21: the risk of surgical site infection is reduced with perioperative oxygen.

Can J Surg 2007 Jun;50(3):214-6

EBRS, Mount Sinai Hospital, Toronto, Ontario, Canada.

Objective: Does supplemental perioperative oxygen reduce the risk of surgical wound infection after colorectal surgery?

Design: Randomized controlled trial.

Setting: Multicentre trial that included 14 hospitals in Spain.

Patients: 300 patients aged 18-80 years who underwent elective colorectal resection. Patients who had surgery performed laparoscopically or who had minor colon surgery were excluded.

Intervention: Patients were randomly allocated to either 30% or 80% fraction of inspired oxygen (FiO2) intraoperatively and for 6 hours postoperatively. Anesthetic treatment and antibiotic administration were standardized.

Main Outcome Measure: Surgical site infection (SSI) as defined by the Center for Disease Control.

Results: SSI occurred in 35 of 143 patients (24.4%) who were administered 30% FiO2 and in 22 of 148 patients (14.9%) who were administered 80% FiO2 (p = 0.04). The risk of SSI was 39% lower in the 80% group (relative risk [RR], 0.61; 95% confidence interval [CI], 0.38-0.98) versus the 30% FiO2 group.

Conclusions: Patients receiving supplemental oxygen have a significant reduction in risk of surgical site infection.

Hospital preparedness and SARS.

Emerg Infect Dis 2004 May;10(5):771-6

McGill University, Montreal, Quebec, Canada.

On May 23, 2003, Toronto experienced the second phase of a severe acute respiratory syndrome (SARS) outbreak. Ninety cases were confirmed, and >620 potential cases were managed. More than 9,000 persons had contact with confirmed or potential case-patients; many required quarantine. The main hospital involved during the second outbreak was North York General Hospital. We review this hospital's response to, and management of, this outbreak, including such factors as building preparation and engineering, personnel, departmental workload, policies and documentation, infection control, personal protective equipment, training and education, public health, management and administration, follow-up of SARS patients, and psychological and psychosocial management and research. We also make recommendations for other institutions to prepare for future outbreaks, regardless of their origin.
