Pedometer-measured physical activity among emergency physicians during shifts

      Abstract

      Objective

      Tools to measure physical activity, such as pedometers, have become more prevalent and attracted popular interest in recent years. Despite this trend, research has not yet quantified pedometer-measured physical activity among Emergency Physicians. This study aims to provide the first characterization of physical activity among on-duty Emergency Physicians in terms of step count.

      Methods

      Emergency Physicians wore Empatica E4 research-grade accelerometers while performing routine clinical care in the Emergency Department. A publicly available algorithm was used to estimate the number of steps taken.

      Results

      Fifty-one Emergency Physicians, including thirty-four residents and seventeen attending physicians, contributed over 1500 h of accelerometer data. On average, this cohort took 577 steps per hour (SD: 72.6), totaling 4950 steps per recorded shift (SD: 737.8), which is approximately 2.6 miles (SD: 0.31). Residents walked more than attending physicians (595.9 steps per hour (SD: 99.7) vs 563.0 steps per hour (SD: 89.0), respectively; p = 0.02).

      Conclusion

      The average emergency physician in this cohort walked roughly half the daily recommended number of steps during their recorded shift. Residents walk significantly more than attending physicians.
