Study flags millions of unnecessary surgeries annually, sparking debate on overuse

The Economist reports that a significant share of the 300+ million annual surgical procedures worldwide may be unnecessary or harmful, citing growing research. The claim is based on expert opinion and observational studies, not a single definitive trial, so the magnitude of overuse remains uncertain. This matters because it could pressure health systems to reform surgical decision-making and reimbursement, potentially affecting medical device and pharma demand.
