Researchers Use WHOOP to Measure Resident Wellness, Prevent Burnout

Study Aims to Use WHOOP Data to Help Identify Warning Signs of Burnout in Medical Residents

Researchers at Penn State College of Medicine are conducting a study to determine if a wearable device can measure wellness and predict burnout among resident physicians. The results from the clinical trial could be used to develop targeted interventions for depression and burnout in graduate medical education.

Dr. Alexander Hajduczok, a third-year internal medicine resident at Penn State Health Milton S. Hershey Medical Center and principal investigator for the study, said that training to become a physician can be stressful and that interventions are necessary to address the growing rates of burnout and depression in residents and other medical professionals, especially in light of the COVID-19 pandemic.

“Prior studies have shown that depression and burnout in residents can increase medical errors and worsen patient outcomes,” Hajduczok said. “We hope that the data we collect from the study can help us identify stress triggers and develop interventions to help residents cope with those challenges.”

The trial recruited 38 internal medicine residents from the Milton S. Hershey Medical Center and began on July 1. Each participant will wear a WHOOP Strap for one year to measure heart rate, respiratory rate, sleep and other physiologic data. The research team will compare the data collected by the device to subjective assessments of wellness and burnout collected in weekly surveys to see if physiologic trends in the data align with how residents report they feel.

Researchers will particularly evaluate heart rate variability (HRV), the fluctuation in the time intervals between adjacent heartbeats, which can be used as a surrogate measure for physical, mental and emotional stress. According to Hajduczok, when residents are subjected to the high levels of stress of medical training, HRV may decrease. He predicts that trends in HRV will be a key indicator of resident wellness, burnout and depression.

In addition to the subjective measures of wellness and remote monitoring with WHOOP, the researchers will also periodically measure salivary cortisol levels as a secondary objective indicator of stress. Cortisol is a hormone involved in metabolism and immune responses that helps the body respond to stressful stimuli.

Hajduczok said the idea for the study came to him while working nights in the Intensive Care Unit during his second year of residency. He was already wearing WHOOP to measure his performance and recovery while training for national CrossFit competitions. He noticed that decreases in his heart rate variability aligned with stressful times in his physical training as well as his medical training.

A previous study by Dr. Jamie Coleman, a trauma surgeon from Denver, used WHOOP to measure how trauma surgeons’ sleep patterns were affected by being on call. Hajduczok and Coleman have shared ideas on using WHOOP for research purposes.

Hajduczok hopes that the results from the study will lead to an increased understanding of the most difficult and stressful parts of residency so that actions to prevent burnout and depression can be taken. He said that measures to address resident stress could include optimizing and possibly individualizing resident schedules, encouraging healthy behaviors such as self-reflection and exercise, and targeting specifically identified systems-based stressors for change.

“Everyone across the medical education spectrum, from medical students to residents to attendings, experiences stress,” Hajduczok said. “This study is evaluating resident stressors, but the findings could have broader implications for the medical community as a whole.”
