As of midnight, Lincoln Fire & Rescue has responded to 3,988 medical emergencies so far this year. That's a 14% increase over the same time last year. I'll be watching this closely as the year unfolds, because it is part of a long-term trend of increasing EMS calls. The growing population of Lincoln is part of the explanation, but my guess is that baby boomers reaching the age where medical needs are greater is bending the curve a bit. There was an 18% increase in the number of citizens over the age of 65 in Lincoln from the 2000 census to the 2010 census--greater than the overall population increase.
