Fighting fatigue: A conceptual model of driver sleep in the gig economy.

The purpose of this paper was to integrate the sleep science, occupational health, and organizational psychology literature to develop a conceptual model of driver sleep and fatigue in the gig economy. We develop an integrative framework, which proposes that aspects of the on-demand driving context influence driver sleep health and fatigue. Driver outcomes include safety incidents, injuries, health, job attitudes, interpersonal behavior, and performance. In addition, moderators, such as driver demographics and health conditions, can interact with aspects of the driver context. A number of practical implications are provided, addressing the ways in which occupational health researchers, online labor platform companies, and drivers can improve sleep health. This is the first paper to provide a broad understanding of how scientists, through both research and practice, can help improve sleep, a primary issue in the ridesharing industry.

The impact of industry and body part injured on repeat workers' compensation claims.

BACKGROUND: Few studies investigate the influence of body part injured and industry on future workers' compensation claims. METHODS: Using claims incurred from 1 January 2005 to 31 July 2015 (n = 77 494) from the largest workers' compensation insurer in Colorado, we assessed associations between worker characteristics, second claims involving any body part and the same body part. We utilized Cox proportional hazards models to approximate the probability of a second claim. RESULTS: First claims represented 74.9% (n = 58 007) and second claims 25.2% (n = 19 487) of total claims. Sex, age, industry, and body part of the first claim were associated with the probability of second claims and the body part affected. The 5-year probabilities of second claims and same body part second claims were 27.0% (95% confidence interval [CI]: 26.6%-27.5%) and 6.2% (95% CI: 5.9%-6.5%) in males and 26.5% (95% CI: 26.0%-27.0%) and 6.7% (95% CI: 6.5%-7.0%) in females. Most second claims occurred within 3 years. CONCLUSIONS: Most second claims occur within 3 years. Body part and industry-specific injury patterns suggest missed opportunities for prevention.
