Using Low-Cost Sensors to Assess Fine Particulate Matter Infiltration (PM2.5) during a Wildfire Smoke Episode at a Large Inpatient Healthcare Facility.

Wildfire smoke exposure is associated with a range of acute health outcomes, which can be more severe in individuals with underlying health conditions. Currently, there is limited information on the susceptibility of healthcare facilities to smoke infiltration. As part of a larger study to address this gap, a rehabilitation facility in Vancouver, Canada was outfitted with one outdoor and seven indoor low-cost fine particulate matter (PM2.5) sensors in Air Quality Eggs (EGG) during the summer of 2020. Raw measurements were calibrated using temperature, relative humidity, and dew point derived from the EGG data. The infiltration coefficient was quantified using a distributed lag model. Indoor concentrations during the smoke episode were elevated throughout the building, though non-uniformly. After censoring indoor-only peaks, the average infiltration coefficient (range) during typical days was 0.32 (0.22-0.39), compared with 0.37 (0.31-0.47) during the smoke episode, a 19% increase on average. Indoor PM2.5 concentrations quickly reflected outdoor conditions during and after the smoke episode. It is unclear whether these results will be generalizable to other years due to COVID-related changes to building operations, but some of the safety protocols may offer valuable lessons for future wildfire seasons. For example, points of building entry and exit were reduced from eight to two during the pandemic, which likely helped to protect the building from wildfire smoke infiltration. Overall, these results demonstrate the utility of indoor low-cost sensors in understanding the impacts of extreme smoke events on facilities where highly susceptible individuals are present. Furthermore, they highlight the need to employ interventions that enhance indoor air quality in such facilities during smoke events.

Improving Pediatric Resident Communication During Family-Centered Rounds Using a Novel Simulation-Based Curriculum.

Introduction: While family-centered rounds (FCR) have become increasingly important in pediatrics, there is often no training for residents on appropriate FCR practice. This curriculum was developed to address this identified gap in pediatric trainee education through a combination of didactic presentation, direct observation, and simulated FCR. Methods: Residents participated in a didactic presentation on key components of FCR and tenets of communication with families. A subset of residents participated in a simulated intervention in which they practiced an FCR encounter using a mock patient case and received immediate feedback from a multidisciplinary team. Following the simulation, residents completed follow-up surveys and focus group discussions to assess their experience and comfort. Resident trainees were observed and rated during FCR by trained parent advisors using a novel FCR checklist both before and after participation in the simulation. Results: This curriculum was implemented with 10 pediatric interns (intervention group). These residents demonstrated statistically significant improvements in the areas of greeting family by name and soliciting rounding preferences, enhancing family comfort in participating in FCR, and increasing family engagement in FCR. Compared to controls, intervention group residents had higher ratings on the majority of performance items. Resident-reported self-efficacy in conducting FCR increased following the intervention, and the feedback portion of the intervention was highly valued. Discussion: Simulation-based training is an effective model for teaching residents best practices in FCR with lasting impact on resident communication skills as seen in comparative analysis from before and after the intervention.
