SESSION TITLE: Late Breaking Pulmonary and Education Topics Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/18/2022 01:30 pm - 02:30 pm PURPOSE: Healthcare professionals working in intensive care units (ICU) report high burnout levels, especially during the COVID-19 pandemic. Residents are particularly at risk for burnout and sleep deprivation, associated with increased medical errors. However, the relationship between sleep, burnout, and psychomotor vigilance has not been extensively studied in residents working in the medical ICU. METHODS: Fifty residents rotating in the ICU at an academic, tertiary care center were recruited for a prospective controlled trial during a consecutive four-week period from August 2021 – May 2022. Study parameters for two weeks in non-ICU rotations were compared with two week during ICU rotation. Residents wore a wearable sleep tracker for two weeks before and during their ICU rotation. ICU rotation dates were randomized based on a fixed annual schedule. Residents ranged in post-graduate training years one through four. Specialties included internal medicine, transitional year, emergency medicine, anesthesia, and medicine/pediatrics combined residency. Data collected included the Oldenburg burnout inventory score, Epworth Sleepiness Scale (ESS), a computer-based psychomotor vigilance test, American Academy of Sleep Medicine sleep diary, and wearable sleep tracker data. Statistical analysis was performed in Excel and R statistical software. RESULTS: Total sleep minutes detected by the wearable sleep-tracker decreased from 402 minutes (95% CI: 377-427) before ICU to 389 minutes (95%CI: 360-418) during ICU (p<0.05). Residents overestimated the amount of sleep they obtained via their validated daily log at 464 (95% CI: 452-476) minutes before ICU and 442 (95% CI: 430-454) minutes during ICU, which reflected a decrease in sleep of 22 minutes (p<0.02). ESS increased significantly from 5.93 (95% CI: 4.89, 7.07) before to 8.33 (95% CI: 7.09,9.58) during ICU (p<0.01). Oldenburg burnout inventory scores significantly increased during ICU by 8.30 (p<0.001). The total score before ICU was 34.50 (95% CI: 32.87-36.15) and after was 42.82 (95% CI: 40.65-44.98). Exhaustion and disengagement sub-scores significantly increased during ICU (3.94, 4.64, respectively;p<0.001). Interestingly, psychomotor vigilance testing scores showed no significant difference during ICU. CONCLUSIONS: ICU rotations are associated with significantly reduced sleep as objectively measured by sleep wearable and decreased self-reported sleep minutes. Residents overestimate the amount of sleep they obtain. Significant worsening of ESS was noted along with increased burnout in residents working in the ICU. Interestingly, the psychomotor testing remains unchanged. Further research is needed in this area to better understand this phenomenon. CLINICAL IMPLICATIONS: Residents may benefit from increased mandatory wellness events or days off to combat burnout and fatigue while in the ICU.
