Studies have reported higher risks of death and other adverse outcomes in acute stroke patients admitted off-hours; however, little is known about the underlying mechanisms. According to time of admission, our aim was to examine compliance with performance measures for acute stroke care processes, including the effect of a systematic quality improvement program, and to examine 30 days case-fatality.A population-based historical cohort study, including patients admitted to Danish hospitals with a first ever acute stroke (January 1, 2003, to December 31, 2011; N=64 975). Off-hours were weekends and evening and nighttime shifts on weekdays. Compliance with performance measures was compared using general linear modeling, and odds ratios for 30 days case-fatality were obtained using multivariable logistic regression.Patients admitted off-hours had a lower chance of compliance with 8 out of 10 performance measures; however, these differences diminished over time. Unadjusted odds ratio for 30 days case-fatality, for patients admitted off-hours compared with patients admitted on-hours, was 1.15 (95
