Medical Overuse in the Iranian Healthcare System: A Systematic Scoping Review and Practical Recommendations for Decreasing Medical Overuse During Unexpected COVID-19 Pandemic Opportunity.

Our review showed, even so, the magnitude of unnecessary overuse of medical services is high but there are only a few interventional studies in clinical and administrative level for finding effective methods for decreasing these unnecessary services. Researchers should be encouraged to conducting interventional studies. We suggest the ministry of health to use the golden opportunity of COVID-19 epidemic for designing Iran national policy and action plan for controlling and preventing unnecessary healthcare services and including a section for "Interventional Research" in the action plan.
