SleepTrackTXT Feasibility and Pilot Study (SleepTrackTXT)

The Sleep Track Text Pilot Trial in Emergency Care Clinicians

Aim 1: To determine if real-time assessments of perceived sleepiness and fatigue using text-messaging impacts an emergency medicine clinician's Attitudes, Perceived Norms, Self-Efficacy, Alertness Habits, Perceived Importance of Fatigue, Knowledge of Sleepiness/Fatigue, and Perceptions of Environmental Constraints regarding behaviors that can improve alertness during shift work.

Aim 2: To determine if text-messaging emergency care workers fatigue-reduction strategies in real-time at the start and during shift work reduces worker perceived sleepiness and fatigue at the end of shift work.

Study Overview

• Status: Completed
• Conditions: Fatigue
• Intervention / Treatment: Behavioral: Text-message assessments only; Behavioral: Text-message interventions for high level fatigue

Detailed Description

More than half (55%) of Emergency Medical Services (EMS) shift workers report severe mental and physical fatigue while at work,(Patterson et al, 2012) 36% report excessive daytime sleepiness,(Pirrallo et al; 2012) and 60% poor sleep quality.(Patterson et al; 2012) Sleepiness or fatigue while on duty can result in injuries to EMS workers and medical errors for patients.(Patterson et al; 2012) The investigators' recent research shows that odds of injury among fatigued EMS workers are 1.9 times higher than non-fatigued workers.(Patterson et al; 2012) Additional data show that other emergency workers (e.g., emergency physicians and nurses) are vulnerable to sleepiness and fatigue while at work.(Fisman et al; 2007; Machi et al; 2012; Thomas et al; 2006; Geiger-Brown et al; 2012).

There are a number of individual and system factors that influence sleepiness and fatigue during shift work for emergency workers. Individual factors include sleep hygiene, medical conditions like obstructive sleep apnea, and other factors.(Schaefer et al; 2012; Simon et al; 2012) System factors include shift length, patient care intensity, and workload. Many factors are modifiable, yet some are more difficult than others to change or control. Reducing shift length and customary patterns of shift work, such as 12-hr and 24-hr shifts, is not feasible for many employers and shift workers in the emergency medicine care setting. In some locations, >80% of EMS workers hold multiple jobs, 40% work more than 16 shifts per month, and many accumulate unsafe amounts of overtime in order to make a livable wage.(Patterson et al, 2010; Patterson et al, 2012; Bauder 2012) Other shift workers in emergency care settings face the same or similar obstacles as do EMS shift workers.

An objective of this research study is to pilot test real-time assessment of emergency care worker sleepiness and fatigue. The investigators seek to determine if text-messaging fatigue-reduction strategies to emergency care workers that report a high-level of sleepiness or fatigue at the start or during their shift reduces perceived sleepiness or fatigue at the end of shift. A long term goal of this research is to determine if this innovative text-messaging tool can be used to reduce the likelihood of fatigue-related injury among emergency care shift workers.

Aim 1: To determine if real-time assessments of perceived sleepiness and fatigue using text-messaging impacts a worker's Attitudes, Perceived Norms, Self-Efficacy, Alertness Habits, Perceived Importance of Fatigue, Knowledge of Sleepiness/Fatigue, and Perceptions of Environmental Constraints regarding behaviors that can improve alertness during shift work.

Rationale: The investigators recognize that emergency care shift workers hold different beliefs and attitudes about the risk of sleepiness and fatigue on duty and are at different stages of adopting risk-reduction behaviors. Behavioral research shows that modifying one or more of these factors can impact future behavior and potentially reduce risk over the long term. Approach: The investigators have developed a list of candidate items that operationalize the Integrative Model of Behavioral Prediction. The investigators will administer these candidate items at baseline and again at the end of the study period to assess impact.

Aim 2: To determine if text-messaging emergency care workers fatigue-reduction strategies in real-time at the start and during shift work reduces worker perceived sleepiness and fatigue at the end of shift work.

Approach: At baseline, the investigators will randomly assign 100 emergency care workers to one of two groups (the control group or intervention group). The control group (n=50 / 50%) will receive standard text-message questions of sleepiness and fatigue at the beginning, during, and end of shift. The other 50% (n=50) will be assigned to our intervention group and receive the same text-message questions as the control group, as well as additional text-messages that include strategies that the investigators hypothesize will lead to a reduction in perceived sleepiness or fatigue at the end of shift work. With 100 EMS workers (50% intervention / 50% control), the investigators have 80% power to detect a difference (effect size of 0.78) in the self-reported fatigue levels reported at the end of shift by the control and intervention groups. The investigators will collect data over a 90-day study period.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Sham Comparator: Control Group; The control group will receive text-message assessments only at the start, during, and end of shift. These queries will attempt to capture the worker's self-reported sleepiness, fatigue, and occurrence of work-related injury during shift work.	Behavioral: Text-message assessments only; Text message assessments only. No intervention for high level fatigue.
Experimental: Intervention Group; The intervention group will receive the same text-message assessments as the control group. In addition, these subjects will receive text-message interventions for high level fatigue for reducing fatigue and sleepiness during shift work if they report a high-level of fatigue or sleepiness at the start or during their shift. These subjects will then receive additional text message queries at the end of their shifts to determine if they adopted a strategy for reducing perceived sleepiness or fatigue.	Behavioral: Text-message interventions for high level fatigue; Intervention messages to promote alertness while on duty at work including activities. Additionally at the end of the shift, participants were queried on their adoption of the suggested activities and perception of the activities' effectiveness.

Environmental Constraints Three Subscale of the SFAB	Degree of importance of personal/work-life barriers that might limit ability to reduce feelings of fatigue and sleepiness while on duty. Scale ranges from 0 (not at all important) to 100 (very important). Higher scores indicate the individual perceives his/her responsibilities unrelated to the organization as factors that inhibit the individual's ability to engage in behaviors that can improve alertness and reduce feelings of sleepiness or fatigue while at work	end of study at 90 day follow up
Habits Subscale of the SFAB	Endorsement of behaviors that may promote improved alertness and reduced feelings of sleepiness or fatigue while at work ranging from 0 (strongly agree) to 100 (strongly disagree). Strongly agree (lower score) is associated with high level of endorsement of behaviors (habits) that promote improved alertness.	end of study at the 90 day follow up
