This research examines how physicians' imaging-ordering strategies affect emergency department efficiency. Using electronic health records and an instrumental variable approach based on random physician assignment, the study finds that discretionary batching of imaging tests increases length of stay by 65% and doubles imaging utilization, ultimately reducing patient flow and safety.

This research tests a new personalised care model for Parkinson’s called Prime Care, offering rapid access to support and tailored interventions based on each patient’s risk of hospital admission. A two-year clinical trial of 214 participants will determine whether this approach improves wellbeing and reduces costly, harmful hospital stays.
