LOUISVILLE, Ky. (WDRB) -- Ambulances becoming a part of fire department fleets is becoming more common throughout Jefferson County.

Several departments around the city have added some, including Harrod's Creek Fire, Anchorage Middletown Fire, Jeffersontown Fire, and soon, Buechel Fire will add one. The increasing number of ambulances gives hope for a decreasing number for response and wait times in the area. 

"The increase in the number of ambulances on the street at any given time is a good thing for the city," said Mitch Burmeister with Louisville Metro Emergency Services. "We want to make sure that every citizen, within Jefferson County as our focus, gets the best emergency health care that they can."

Louisville Metro Services said 2017 data shows Jefferson County had an average wait time of eight minutes and fifty-two seconds. The national average for a serious call such as a heart attack is about eight minutes. Burmeister said the dispatch center is always extremely busy, and the dispatch system can be very complex, especially when there are more calls than ambulances.

Mike Riordan, St. Matthews Fire Department EMS Chief, said his data shows a decrease in response times in St. Matthews since EMS was added to their department. Riordan said he understands the dispatch center has the most difficult job in emergency services, especially when some of the ambulance do not have location trackers, but hopes the addition of EMS to fire departments helps the entire county.

St. Matthews will be adding a new ambulance to its fleet this weekend, and Buechel will have an ambulance on the streets in the coming months.
