In this episode Dr. Sachin Pendharkar explores overcrowded or access-limited healthcare systems and suggests that discussions of supply and demand are often inappropriately limited to lack of supply.

After listening to this podcast, listeners will: 

  • Understand that problems with overcrowding and long wait times are not always due to inadequate supply. 
  • Be aware of concepts of demand, supply and capacity and how they relate in healthcare systems. 
  • Recognize how variation can be a barrier to access, even in systems with an adequate supply to meet demand.
