Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A randomized two-group cross over design will be used to test the hypothesis that using real-time biofeedback to present, interpret, and bring attention to information regarding stress levels will increase participants readiness to change in regard to addressing burnout. To test this hypothesis, the investigators will recruit 80 providers from Federally Qualified Health Centers (FQHC) partner sites to participate in a 6-week cross over design. The study includes two feedback periods: (1) 21 days of immediate information: (2) 21 days delayed information period. Participant conditions will be switched on day 22. All participants will be given a wrist worn sensor developed by Biostrap. Biostrap collects biometrics such as the following: (1) sleep pattern/ quality; (2) steps, activity, calories; (3) heart rate/ Heart Rate Variability (HRV); (4) respiratory rate. Participants will be randomly assigned to one of two groups, and either receive immediate or delayed feedback from the sensor first and will then be crossed-over to receive the opposite type of feedback. While wearing the Biostrap wrist-worn sensor, participants will be asked to complete two daily questions sent via the API. The first question seeks to determine if participants accurately understand their biometric data and will ask "how stressed are you today?" (Scale 1-10). The second question seeks to determine if participants attended to the information regarding their stress level and will ask "did you complete a self-care activity today?" (yes/no). A pre and post assessment will be given before and after completing the six-week wearable protocol. Items will include: (1) 2-item depression screener (Patient Health Questionnaire-revised) (2) 2-item anxiety screener (Generalized Anxiety Disorder Scale- revised) (3) 4-item brief resilient coping scale (4) 22-item burnout assessment (Maslach Burnout Inventory) (5) Self-care/supportive psychosocial programs utilization(e.g., I participate in an employee wellness program through my employer) (yes/no) (6) Basic demographics (e.g., age, sex, race, ethnicity, job category, years in field) (7) Familiarity and self-efficacy using wearable sensors (8) Self- report medication list (pretest only).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Days in Concordance Comparing Immediate Information Period With Delayed Information Period
Time Frame: 6 weeks
The proportion of days in concordance was calculated based on responses to two questions. The first question seeks to determine if participants accurately understand their biometric data and will ask "how stressed are you today?" (Scale 1-10 a score of 6+ was coded as "high stress"). The second question seeks to determine if participants attended to the information regarding their stress level and will ask "did you complete a self-care activity today?" (yes = 1 /no = 0). Concordance was coded when participants either a) reported a high level of stress and engaged in self-care or b) when participants reported low levels of stress and did not engage in self-care. Percentage of days in concordance was calculated for both 21-day feedback periods (immediate versus delayed).
6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Burnout Score From Baseline to Follow-up (Pre/Post Sensor Data Collection)
Time Frame: Baseline - 6 weeks
The investigators measured the change in the burnout score in all participants between baseline and 6 weeks follow-up. Maslach Burnout Inventory - Human Services Survey for Medical Personnel (MBI-HSS-MP) is a 22-item survey that covers 3 areas: Emotional Exhaustion (EE), Depersonalization (DP), and low sense of Personal Accomplishment (PA). Each subscale includes multiple questions with frequency rating choices of Never (0), A few times a year or less, Once a month or less, A few times a month, Once a week, A few times a week, or Every day (6). The total score is calculated by summing the three sub-scales and ranges from 0-132 with high scores reflecting higher symptoms of burnout and low scores reflecting fewer symptoms of burnout.
Baseline - 6 weeks

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Mean in Total Burnout Score of Immediate Then Delayed Arm to Delayed Then Immediate Arm
Time Frame: Baseline - 6 weeks
The investigators measured the mean in the total burnout score of the immediate then delayed arm to the delayed then immediate arm. Maslach Burnout Inventory - Human Services Survey for Medical Personnel (MBI-HSS-MP) is a 22-item survey that covers 3 areas: Emotional Exhaustion (EE), Depersonalization (DP), and low sense of Personal Accomplishment (PA). Each subscale includes multiple questions with frequency rating choices of Never (0), A few times a year or less, Once a month or less, A few times a month, Once a week, A few times a week, or Every day (6). The total score is calculated by summing the three sub-scales and ranges from 0-132 with high scores reflecting higher symptoms of burnout and low scores reflecting fewer symptoms of burnout.
Baseline - 6 weeks
Change in Mean in Total Depression Score of Immediate Then Delayed Arm to Delayed Then Immediate Arm
Time Frame: Baseline - 6 weeks
The investigators compared the mean in total depression score of immediate then delayed arm to delayed then immediate arm. The score is a 2-item depression screener (Patient Health Questionnaire-revised). The range is from 0 to 6. The high scores reflect higher symptoms of depression, and low scores reflect fewer symptoms of depression.
Baseline - 6 weeks
Change in Mean in Total Anxiety Score of Immediate Then Delayed Arm to Delayed Then Immediate Arm
Time Frame: Baseline - 6 weeks
The investigators compared the mean in total anxiety score of immediate then delayed arm to delayed then immediate arm. The score is a 2-item anxiety screener (Generalized Anxiety Disorder Scale- revised). The range is from 0 to 6. The high scores reflect higher symptoms of anxiety, and low scores reflect fewer symptoms of anxiety.
Baseline - 6 weeks
Change in Mean in Total Resilience Score of Immediate Then Delayed Arm to Delayed Then Immediate Arm
Time Frame: Baseline - 6 weeks
The investigators compared the mean in total resilience score of immediate then delayed arm to delayed then immediate arm. The score is a 4-item brief resilient coping scale. The range is from 4 to 20. The high scores reflect higher resilience, and low scores reflect lower resilience.
Baseline - 6 weeks
Change in Mean on Participant Sleep Score Between Immediate Information Period and Delayed Information Period
Time Frame: 6 weeks
The investigators measured the change in the participant sleep efficiency score in all participants between the 2 conditions to compare the difference across the conditions. Sleep efficiency score is measured via the wearable sensor. It is comprised of the following information: sleep duration (end-start), minutes in light sleep, minutes in deep sleep, stages of sleep (e.g. REM), arousal count. The range is from 0 to 100. Higher sleep efficiency scores reflect better quality sleep. Low sleep efficiency scores reflect poor quality of sleep
6 weeks
Change in Mean on Participant Activity Level Score Between Immediate Information Period and Delayed Information Period
Time Frame: 6 weeks
Activity level was measured by number of steps and distance measured by the wearable sensors. Higher scores reflect more activity while lower scores reflect less activity. An average of the daily activity level scores was calculated for each information period. Biostrap company calculated the activity score using the activity distribution over the course of a 24-hour window, emphasizing consistent physical activity of 500 steps per hour during 12 unique hours. There are no scale ranges for this activity score.
6 weeks
Change in Respiratory Rate Between Immediate Information Period and Delayed Information Period
Time Frame: 6 weeks
Respiratory rate was measured as breathing rate per minute and was recorded via the wearable sensor. Higher values reflect faster breathing which is a proxy measure of stress while lower values reflect slower breathing. An average respiratory rate was calculated for each information period.
6 weeks
Change in Participant Heart Rate Variability (HRV) Between Immediate Information Period and Delayed Information Period
Time Frame: 6 weeks
HRV was calculated using root mean square of successive differences (rMSSD) using beats per minute recorded via the wearable sensor. HRV scale is 0-255. Normal scores depend on age and sex. HRV is used as a proxy measure of stress and cardiovascular health. An average HRV was calculated for each information period.
6 weeks
Change in Participant Heart Rate Between Immediate Information Period and Delayed Information Period
Time Frame: 6 weeks
Heart rate is measured as beats per minute and was recorded by the wearable sensor. High values reflect faster pulse while lower values reflect lower pulse. Normal ranges for resting adult heart rate is 60 to 100. Higher heart rate is a proxy measure for stress and anxiety. An average heart rate was calculated for each information period.
