I believe that "drawn a new light" has no particular/different meaning in this case here. I think that "drawn" here means the same as "shown, revealed/demonstrated = brought to light". As for "light", it probably means "a way of looking at (something) or considering a matter = an aspect". So, you can get this idea here: ''The soaring price of health care has shown / revealed a new aspect on an interconnected..." In regards to your second question, "rejigger" means the same as "change, readjust or rearrange (something)". It means that "health plans have been readjusted (in their own ways) so that people would have to spend even more money on their medications at the pharmacy" The expression "up in arms" means the same thing as "very angry or upset about something", "in armed rebellion". So, if a person is up in arms about/over something, they are just very angry about it and are protesting strongly = in this case, ''patients, parents and politicians are very angry over the increasing costs of medications'' Hope that helps!

1. "draw a new light" is a weird expression, and I've never heard it before. I googled it and I didn't find anything either (other than instructional videos on how to draw light bulbs!). I think that the writer is using it incorrectly. He meant to say, "shone new light," which means "to reveal something." 2. "to rejigger" means to reconfigure something; to change it somehow. In your example, it means that health care plans have been changed so that patients have to spend more money on their own medications. "to be up in arms" means that people are extremely angry and are protesting about something. In your example, patients, parents, and politicians are angry about the increasing costs of medications.
