  • My research is focused on demand and capacity imbalances in emergency care
    and how this impacts patient outcomes. We recently published a study on how
    hospital bed occupancy impacts patients and the emergency departments:
    Association Between Hospital Bed Occupancy and Outcomes in Emergency Care: A
    Cohort Study in Stockholm Region, Sweden, 2012 to 2016. [1]

    We did not find a significant association between higher bed occupancy and
    increased 30-day mortality, but clear evidence that a higher bed occupancy
    has a negative impact on the workload in the emergency department. As a next
    step we are investigating if demand capacity imbalances (crowding) in the
    emergency departments are associated with increased 30-day mortality,
    increased revisits for discharged patients and increased hospital length of
    stay for admitted patients.
