Patients who are admitted to the intensive care unit on weekends are more likely to die in the hospital than patients admitted during the week, according to an analysis of 10 international studies.
Researchers analyzed data from studies in North America, Europe and Asia and compared the time of admission to the ICU with the rate of death among patients.
The findings show no clear link between nighttime admission and death, but patients admitted on the weekend had an 8 percent higher chance of dying compared to those admitted on a weekday, Reuters reports.
The researchers, led by Dr. Rodrigo Cavallazzi of Thomas Jefferson University in Philadelphia, believe that weekend staffing factors — higher doctor-to-patient ratio, staff fatigue and delayed diagnostic tests — could be to blame for the higher death rate.
The study was published in the medical journal Chest.
