Latest figures reveal that December 2018 was London Ambulance Service’s busiest month on record Frontline ambulance crews in the capital treated almost 101,000 patients – around 7,000 more than the monthly average for last year. Director of Operations Paul Woodrow said: “Demand on our services continues to rise year on year. December is a particularly busy month for us due to Christmas festivities and winter illnesses and injuries. “We plan carefully for periods of increased activity and put more staff on the road and in our control rooms to meet the increased demand. As a result, every day in December 2018 we reached our most seriously ill and injured patients (category 1 calls) in less than seven minutes.
