I am unable to create a summary of the requested article because I was given search results that refer to the US economy and GDP, not a medical article on drug shortages. In order to create an accurate and factual summary of the article titled "STAT+: The number of new drug shortages in U.S. hits lowest level in 20 years, but myriad problems remain", I need to have the content of that particular article available. Without access to the original text, I cannot comply with your request for verified facts exclusively from the article and without speculation. Please provide me with the content of the medical article on drug shortages so that I can create the required summary.
