Introduction: Live-in formal caregivers spend consecutive days in patients’ homes, raising questions about their ability to secure adequate sleep while on duty. Few studies have examined sleeping conditions and outcomes for this growing workforce. Methods: We collected weeklong sleep logs and interview data from 32 Filipino caregivers in Los Angeles who provide live-in services at least 3 consecutive days per week. Results: Respondents recorded a total average of 6.4 sleep hours during workdays divided over 2.4 sleep periods. Caregivers rated sleep quality as lower while at work; over 40% indicated excessive daytime sleepiness. Female caregivers reported worse sleep outcomes than their male counterparts. Some variations in sleep outcomes were found by employment arrangements. Conclusion: Live-in caregivers experience frequent sleep interruptions at all hours of the day and night to attend to patients’ needs. The resulting impacts on sleep quality pose risks for both work-related injury and errors in patient care. Am. J. Ind.
