It’s no game, but it does take special teamwork during the World Series for hospitals to treat the fans. Between the emotions and the libations – Cubs fans may need hospitalization this weekend.

They're flying the ‘W’ -- supporting the Cubs and their fans. The emergency room at Advocate Illinois Masonic Medical Center -- just blocks from Wrigley -- is bracing for a banner weekend after seeing a 20 percent increase in patients during home playoff games.

Registered Nurse Anna Scaccia, emergency department director, Advocate Illinois Masonic Medical Center: “Especially after the bars closed, we did see an increased amount of patients coming in. Falls, injuries, lacerations. It was very significant, hence why we are increasing our employees during that time.”

Scaccia says the hospital will have extra nurses, doctors and public safety officers on duty this weekend, a familiar drill for the team well versed in caring for crowds – from Pride Parade spectators to Wrigleyville bar goers.

Scaccia: “Be aware of your surroundings. Safety is our number one priority. Watch your alcohol intake. Know when to stop and please make sure you have a safe ride home, have a buddy have a partner.”

But with so many fans’ hearts set on a World Series victory – it’s those with weak hearts who need to take extra precautions.

Scaccia: “This could increase their level of anxiety, hence exasperating some of their cardiac issues.”

With every swing of the bat blood pressure and heart rate can surge. It’s something Scaccia has seen herself while working the first aid station inside Wrigley Field.

Scaccia: “We do have emergency room nurses and physicians in the first aid stations at all times. We did have a patient that needed to be transported here. Taking their medication as prescribed per their physician, trying to stay as calm as possible. I know that can be difficult.”

The hospital is already designating extra beds in areas not typically in use during the weekend, something called code triage stand by -- a contingency plan for a large volume of patients.
