Unlike the AASM's earlier practice parameters, which addressed circadian rhythm sleep-wake disorders broadly and offered recommendations for commonly used interventions, the new document builds on that foundation by applying a systematic, evidence-graded approach to evaluate the benefits and potential harms of treatments aimed specifically at shift work disorder. The disorder is characterized by excessive sleepiness, sleep disturbance or insomnia, or both, resulting from circadian misalignment and insufficient sleep, and it is commonly encountered in both primary care and sleep medicine settings. "There is no one-size-fits-all solution for shift work disorder," said lead co-author Kenneth P. Wright, Jr., who holds a doctorate in behavioral neuroscience and psychology and is a professor of distinction in integrative physiology and director of the Sleep and Chronobiology Laboratory at the University of Colorado Boulder.

"Our recommendations reflect the reality that patients have different schedules, symptoms, and constraints, and clinicians need flexible, evidence-based strategies to help them function safely and sleep effectively." That emphasis on individualization runs throughout the guideline, which directs clinicians to tailor treatment to each patient's symptom profile, work schedule, and personal preferences. For adults whose dominant complaint is excessive sleepiness, the guideline suggests the use of armodafinil or modafinil to improve alertness during night shifts, a recommendation supported by moderate-certainty evidence.

Beyond those two wake-promoting medications, the guideline suggests consideration of caffeine alone, bright light combined with caffeine, and strategic naps paired with caffeine, as well as select circadian-based interventions such as scheduled bright light exposure or adjustments to meal timing. For these latter approaches, the certainty of the underlying evidence is low, and the guideline explicitly notes that benefits may vary across individuals. For patients whose primary difficulty lies in initiating or maintaining sleep, the guideline suggests cognitive behavioral therapy for insomnia, melatonin or melatonin receptor agonists, and certain hypnotic agents timed to support sleep in relation to the individual's work schedule.

At the same time, the AASM suggests against the use of some hypnotic agents whose risk-benefit profiles are unfavorable, including some benzodiazepines, reflecting the task force's effort to weigh potential harms alongside expected benefits rather than simply cataloguing available drugs. A third set of recommendations addresses circadian adaptation itself, targeting the underlying misalignment between the body's internal clock and the hours demanded by the job. Here the guideline suggests timed bright light exposure, consistent sleep scheduling when feasible, and light-filtering strategies during the commute home, with the goal of better aligning the endogenous circadian system with required work hours.

These strategies acknowledge that shift work disorder is not merely a matter of poor sleep habits but a physiological mismatch between biological timing and occupational demands. The task force behind the guideline was commissioned by the AASM and composed of experts in sleep and circadian medicine. Its members systematically reviewed the published literature and developed updated recommendations for the management of shift work disorder while taking into consideration the certainty of evidence, the beneficial and harmful effects of each intervention, patient values and preferences, and resource use.

A draft of the guideline was posted for public comment before the AASM board of directors approved the final recommendations, a process designed to incorporate both expert judgment and broader stakeholder input. Throughout the document, the guideline highlights the limited quality of evidence available for many of the interventions it evaluates, a candid acknowledgment that even widely used approaches to shift work disorder rest on comparatively thin empirical foundations. In light of that uncertainty, the guideline underscores the need for shared decision-making between clinicians and patients, in which the strength of the evidence, the likelihood of benefit, and the potential for harm are discussed openly before a treatment plan is chosen.

The authors also call for further research to strengthen the evidence base supporting circadian and behavioral strategies. The guideline was endorsed by the Australasian Sleep Association, the Society of Behavioral Sleep Medicine, the Nurse Practitioner Association of Canada, Sleep Charity, Project Sleep, and the Sleep Health Foundation, signaling broad professional and patient-organization support across multiple countries.
